foreword

For climates sake!

Traditionally, efforts to improve the sustainability of the clay brick sector have been mostly geared towards adopting more sustainable practices in clay brick production. However, when considering the environmental impacts of clay bricks over their life-cycle, the use-phase has shown to have a greater environmental impact than the production-phase in terms of the building’s energy consumption and greenhouse gas (GHG) emissions over its lifetime.

The Clay Brick Association of South Africa (CBA), EcoMetrix Africa and Partners for Innovation have been commissioned to execute a project funded by the European Union under the SWITCH Africa Green programme entitled: ‘Promoting Inclusive Sustainable Practices in the South African Clay Brick Sector’.

This will enable us to focus on the use-phase of clay bricks focussing on how the clay brick sector can play a bigger role in the sustainable building sector (SBS) and promote the uptake of sustainable building practices (SBPs) in South Africa.

It is envisaged that this project will form the basis for the formulation of an action plan which will detail solutions that can be implemented to overcome barriers to promoting and implementing sustainable business practices in the South African clay brick sector, as well as strengthen the enablers to facilitate sustainable business practices.

The overall objective of the SWITCH Project is in line with the CBA’s vision statement. The CBA is a member-based industry association which creates awareness, shares knowledge and provides support and capacity building related to various aspects of the clay brick value chain in South Africa. Ensuring that clay brick production and use contribute to the sustainable development of the country is an imperative for the CBA. This is demonstrated through the association’s vision statement: ‘To supply society with good quality, durable clay bricks for a sustainable future’.

Mariana Lamont, Excutive Director at The Clay Brick Association of South Africa (CBA).

ed’s letter In celebration of our 25th edition, To Build has some important changes in its presentation, some of which are based on feedback from our highly valued readers.

Gareth Griffiths

In this edition we have a built environment industry feature, in addition to our regular sector and product divisions. This time around, it is the Steel Awards 2018, the South African Institute of Steel Construction’s glittering annual windup and competition of all qualifying projects involving steel construction this past year.

Supporting this, we have up-to-date steel industry commentary, technical articles and a personality profile of a senior steel industry executive, Colin Hautz, CMO for ArcelorMittal.

We cover elements of the 2018 Green Building Convention held in October in Cape Town, once again featuring top drawer international speakers.

Our legal eagle shares his thoughts on the ruling by the Constitutional Court of South Africa that private cultivation and consumption of marijuana is now legal and what impact this could have on building sites or the shop floors of South Africa.

As to the general environment in which the building industry finds itself, 2018 has proved to be a highly challenging year.

There have been overriding issues such as the cost and availability of electricity, rocketing fuel prices, political instability and the worst drought recorded in a decade in areas of South Africa.

Developers are reporting new problems on building sites and in some centres including Cape Town, whole developments are being put on hold due to misdirected activism aimed at planning authorities by way of objections to land use and other departure applications. These actions have had the consequence of stopping work on site indefinitely and leading to layoffs, job losses and even the closures of firms. How can any activism justify these huge blows to the economy? In the Cape Town CBD alone, the Western Cape Development Forum informally estimates that up to R5-billion in construction value alone is threatened, along with up to 4 200 job opportunities lost.

To Build asked the relevant MMC Cape Town for a view on these sector losses, but such view was not forthcoming; instead we were sent a rather broad development policy document which offers little relief to the challenges that the construction industry currently faces.

Kind Regards Gareth Griffiths editor@tobuild.co.za www.tobuild.co.za

Voice of SAIA

Architects responsible for award-winning designs

Corobrik SAIA Awards recognising excellence in design The prestigious Corobrik SAIA Awards programme is run nationally every two years and this year saw the culmination of the cycle begun at the beginning of last year.

The South African Institute of Architects (SAIA) mission is to act as the collective voice serving the interest of its members in pursuit of excellence and responsible design. We aim to uphold the dignity of the architectural profession and contribute meaningfully to the enhancement of society and the environment. The Corobrik SAIA Awards programme supports SAIA’s mission by recognising and promoting excellence in architecture.

The adjudication panel met first over two days in December 2017 to shortlist the projects for in-loco inspections. During these two days, the adjudication criteria were discussed and the exhibition of all 61 entries reviewed. The adjudicators shortlisted 47 projects for inspection.

The adjudication panel viewed some exceptional projects of various scales and complexities. All had one thing in common; clients who were passionate about their projects and thus dedicated to their success.

At the end of the process, the adjudicators conferred 6 Awards for Excellence, 25 Awards of Merit and 5 Commendations.

Looking to the future, the adjudicators and the South African Institute of Architects wish to encourage the submission of more projects of a social and developmental nature in the years to come.

COVER SToRY ALLIANCE

Alliance: A home-grown South African success story Photos by Fourways Airconditioning and Gareth Griffiths Imaging

In 2006, Fourways Airconditioning launched their own airconditioning brand in South Africa, providing a medium-priced, high quality range of products for the local market.

Today, Alliance’s current airconditioning range includes both inverter and non-inverter split units and portable units for the residential market, as well as cassettes, ducted, rooftop units, under ceilings, floor standing units, air curtains and even a recently-launched air-to water generator that literally produces water from air.

After the Energy Usage in Building Regulations (XA2) law came into being in 2011, it became clear to Fourways that this was an opportunity.

They launched a range of top-quality Alliance heat pumps, from small retro-fitted domestic units and pool heat pumps to larger direct heating commercial units, 70°/80° high temp commercial models and commercial swimming pool heat pumps.

Today, backed by nine Fourways Airconditioning branches with warehouses around the country along with technical support, Alliance products have truly become a home-grown South African success story.

Alliance contributes to the “greening” of South Africa

The Agricultural Research Council (ARC) in Stellenbosch is one of those interesting organisations

quietly beavering away, intent on improving the future of agriculture in South Africa. One of their projects involves growing and testing the development of plants in a temperature-controlled environment.

By carefully regulating the interior temperature of glasshouses, ARC conducts studies on plant growth throughout the year, protecting plants from changing external temperatures. In this way, they can determine the best possible conditions for the development of plant growth using statistically comparable conditions.

Greater energy efficiency required

While ARC’s glasshouses had been in existence for a number of years, it became obvious that a more energy-efficient method of controlling the temperature of glasshouses was required. The old rooftop airconditioning units were anything but economical in terms of energy usage.

Louwco Cooling Solutions became the preferred bidder on a tender. Managing Director, Marius Louw, who had had previous dealings with Fourways Airconditioning Cape, asked for assistance. The tender

Alliance inverter units ensure precise temperature control

Sampson Booysen of ARC Stellenbosch with Marius Louw and Andre van Niekerk of Louwco Cooling solutions .

called for inverter-type rooftop units. There was no company in South Africa that had suitable units in stock.

Mfundo Ciko, a Director of Fourways, on a trip to China, had examined units of this type for addition to the Alliance range here. Following his recommendations, an order was placed in May 2018 for 12 x 26kW full inverter Alliance rooftop units and these were delivered in August.

Wasting no time, Louwco Cooling installed these in September and with the help of Fourways Airconditioning, commissioned them at the end of the month. The job included fabricating suitable ducting to conform to the requirements of the new Alliance units.

A key issue in the installation was the accurate maintenance of interior temperatures inside the glasshouses. Due to the fact that the Alliance units are fully inverter, compressor speeds can be varied to ensure precise temperature control.

‘While the old units were running at 18 amperes, the new Alliance units – depending on temperature and capacity of the greenhouse interior – can drop to as little as 8.5 amperes. On average, we thus estimate an energy saving of at least 32% over the old units,’ says Louw.

‘We are grateful for the expert assistance we received from Fourways Airconditioning Cape, in the expediting of the order the prompt delivery and their follow-up on site. We now look forward to hearing from ARC in the longer term about precisely what the energy saving is of these new Alliance units we have installed,’ he adds.

‘Fourways is proud to have its Alliance units contributing to the further “greening” of South Africa – in more ways than one!” says Ciko.

Massive growth in

Fourways’ export sales

S

ales success – followed by subsequent expansion – has been the hallmark of Fourways Airconditioning ever since its start in small Kya-Sands premises back in the early 2000’s.

South Africa provides units and spares when required and also offers technical assistance in any area where it is required. Training of installers in export countries is provided in their regions as well as occasionally in Fourways offices in South Africa.

Three branches have expanded into the current nine since then, ensuring South Africa-wide support for Samsung and Alliance airconditioners. Now Fourways has looked further afield – with ever-continuing success – up into Africa and even across the Indian Ocean to Mauritius.

Director Duncan Mackinnon who is heading up Fourways Airconditioning’s export drive.

Promoting export sales

In charge of export sales is Director Duncan Mackinnon who now spends some 80% of his time pursuing sales there as well as also looking after Fourways KZN part-time.

Eden Island Hotel, Seychelles; Radisson Hotel, Gabon

7 African countries plus Mauritius

Botswana was the first African country that Fourways exported to back in 2002 and since then Malawi, Mozambique, Namibia, Swaziland, Zambia, Angola and Mauritius have all come aboard. In addition, Fourways has also dealt with countries as far afield as Seychelles and Gabon. Fourways now has its own office in Mauritius visiting consulting engineers and end users to ensure that our product is specified. Although Fourways has a bond store in Durban which is used for export purposes, Fourways also does direct deliveries from the factory to various countries. In addition, we also have a bond store in Mauritius.

After-sales service and parts

In order to ensure full back-up of Samsung and Alliance products in export countries, accredited dealers have been appointed who install, repair and maintain. Fourways Gauteng:

Pretoria:

(012) 643-0445

Bloemfontein: 083 381 0074 George:

He comments: “We now have an excellent team aboard handling exports. Graziano (‘Grats’) Wolfaardt has been appointed to pursue sales in a number of adjoining African countries, while back at Fourways Johannesburg, Mandi Hayden is handling the internal processing of orders and spares as well as building an internal sales relationship with export clients. And everyone at Fourways – from the MD and Financial Director to the warehouse staff – are getting 100% behind our export drive. We’ve always operated as a family at Fourways, and the same dedication, loyalty and team effort is now being applied to our export thrust.”

The result: an estimated 100%+ increase in export sales this year!

Already by the end of June this year, Fourways Airconditioning had reached almost the same overall export sales total as was achieved for the whole of 2017.

Says Richard Perry, MD of Fourways Airconditioning South Africa: “Looking at our figures for 2018, it seems we are likely to exceed our total 2017 export sales by over 100% this year, and we greatly appreciate the excellent support we have had from neighbouring countries as well as the hard work done by Duncan and his whole team.”

LEAD STORY APPROACHING NET ZERO

Racing to Zero Photos & WORDS by Gareth Griffiths

The 11th annual Green Building Convention entitled The Race to Zero, took place early in October in Cape Town and once again raised the bar on the delivery of an informative and impactful annual source of reference.

Opening the first convention plenary session, GBCSA President, Faieda Jacobs, made reference to the collaborative relationships that the GBCSA with the four C40 Cities (Tshwane, Johannesburg, Cape Town and Durban) Departments of Public Works and Environmental Affairs, South African Local Government Association NHBRC and the GBCSA look forward to expanding to reach all key public sector stakeholders.

‘Four of South Africa’s major metros are participating in the C40 South Africa Building Programme as part of their commitment to be carbon neutral by 2050. This is a commitment aimed at advancing implementation of the Paris

Agreement. GBCSA supports the open dialogue and information sharing between government stakeholders and agencies, the private sector and civic bodies required to help achieve this necessary goal,’ she said.

Green Building Council SA (GBCSA) CEO, Dorah Modise, went on to explain the significance of the GBCSA celebrating its 400th certification during September 2018.

Simply put, the physical impact of this has meant among other things: • 5 700 000m2 of developed property is now Green Star Africa certified, meaning a significant lowering of their environmental impact.

• the area of certified property covers 800 rugby fields, and that • the equivalent of 530-million litres of potable water has been saved.

‘Since inception, significant progress has been made considering the starting point was a zerobase programme with no awareness mindset for many of the professional roleplayers, although assistance was available from the organised green building movement internationally, notably Australia. Now, the model has been rolled out continent-wide with the certification of African property as far afield as Mauritius. Clearly walking the talk, the GBCSA’s newly fitted office block was recently awarded a 4 Star rating by the Interiors Rating Tool. Now, the implementation of our new Net Zero certification sets the bar at zero impact such as at 78 Corlett Drive in Johannesburg which achieved its Net Zero Energy certification,’ Modise explains.

‘More recently the organisation has identified a great need for the raising of awareness levels among the hundreds of small operators in the SMME sector. Assisted by JP Morgan, plans are afoot to roll something out in this sector shortly,’ she adds.

DRAWDOWN – the lowdown

Inspirational speaker, Paul Hawkin, author of DRAWDOWN and its sequel, REGENERATION, speak of the reality of the global crisis, reinforcing the sobering facts that CO2 levels in the atmosphere are at their highest levels in 400 000 years, as illustrated by the ongoing readings being taken from north Greenland icecap.

As a visitor to the drill site located in an ice-cave, Hawken presented a graphic overview of the reality facing humankind. He is a critic of the sensationalist way that the effects of climate change is being

Paul Hawken

represented in the media, offering the alternative view that society should embrace the changes coming and rather present a solid course of action to humankind.

He is critical of the rather arbitrary nature of the Paris Agreement not to exceed 450ppm of CO2. In reality, a truer estimate is the CO2e level (carbon dioxide equivalent), which is 492ppm already.

Coupled with this, the continued commitment by global super powers to burn remaining underground carbon reserves would lead to a chillingly “game over” scenario as far as the future of the human race on the planet is concerned.

However, Hawkin says this is where humankind needs to take a stand to assess what knowledge

it already has and how this can be harnessed on a coordinated basis. He postulates that there is no single fix for this problem, such as setting arbitrary targets, but rather a basket of measures – some of the changes, that if applied, can mathematically and cumulatively offer a process for carbon removal or sequestration.

Project Drawdown presents itself as the most comprehensive plan ever proposed to reverse global warming, where hundreds of possible solutions to individual causes of global warming were studied and then brainstormed by a fellowship of experts via the Drawdown Fellowship Programme (www.drawdown.org/fellowship-program). The solutions proposed, of which there is a short list of 80, involve both physical and societal interventions which collectively work together to reduce carbon emissions.

‘These initiatives improve lives, create jobs, restore the environment, enhance security, generate resilience and advance human health,’ says Hawken.

In short, Project Drawdown gathers and facilitates a broad coalition of researchers, scientists, graduate students, PhDs, post-docs, policy makers, business leaders and activists to assemble and present the best available information on climate solutions to describe their beneficial financial, social and environmental impact over the next thirty years (www. drawdown.org) Many of the measures identified by the collaborative work of the fellowship programme are extremely simple, such as a stimulated return to an agrarian economy involving the work of women small-scale farmers in certain countries.

The top seven measures within the reach of humanity include, with net CO2 equivalent reduction achievable in gigatonnes per annum by the year 2050: 1. Refrigerant management - 87.74 2. Onshore wind turbines - 84.6 3. Reduce food waste - 70.53 4. Favour a pant rich diet - 66.11 5. Tropical forest restoration - 61.23 6. Educating girls (to same level as boys) - 59.6 7. Family planning - ensure dignity of women and children 59.6 Significantly, three of these items require behavioural change by humans or social changes. volume 8 | issue 3 www.tobuild.co.za

LEAD STORY CYBERTECTURE

Undoing a dangerous way to live Photo-renderings by James Law Cybertecture & Photo by Gareth Griffiths WORDS By Gareth Griffiths

Hong Kong international architect and progressive designer, James Law, wowed the audience at the recent Green Building Convention 2018 with a narrative of how the urbanscape of Hong Kong presents inhabitants with huge challenges with highly expensive single-room accommodation for rental costs of up to 60% of the tenant’s monthly take home pay.

The result of this is single, retired or low-income workers living in “caged” areas that include a bed and very limited storage space, which can be locked up and left during the day. Others simply live on the street. In the words of Law, ‘a very dangerous way to live’.

Law and his co-workers developed and nurtured a concept using disused underground 2.5m concrete stormwater piping, which is easily joined end-to-end to form several square feet of habitable space. Due to the ubiquitous nature of these large and sturdy underground pipes, they are accessible and cheap and can be stacked together to form multiple accommodation units. Inside, the curved surfaces of the pipes receive an exhaustive makeover, giving walk-through spaces that include a living area, food preparation area, bedroom and bathroom – along a 5-metre expanse of pipe. Each OPOD is equipped with smart phone locks for

online access, as well as space-saving furniture that maximises the space inside.

The beauty of the scheme is that units may be assembled completely offsite and delivered in-situ, thus expediting the delivery of affordable rental accommodation to a sector of the housing market in dire need. The total cost of one prefabricated unit is as low as $15 000.

Law calls this innovation ‘cybertecture’. He says it takes four hours to move a fully assembled OPOD onto site in Hong Kong. Finished units can be stacked in disused space under bridges and even on top of ferry terminals, so tight is the space on the island.

To kickstart his project, his company was granted a disused site and 20 OPOD units assembled and stacked on top of each other. Occupants were selected based on criteria that required a rental payment for each unit of $300 per month.

CYBERTECTURE LEAD STORY

A completed OPOD

Depending on personal development criteria, such as obtaining a higher education, each occupant can be refunded $200 per month for the duration of their contract; in Law’s words, ‘to give back’. The latter earned Law a standing ovation at the Green Building Convention.

Avoid what we became

Law quickly points out, however, that such interventions are only necessary because of the very poor track record of building planning and development in Hong Kong, going back decades, which he does ‘not wish on any city in the world’.

‘Cities of the world should avoid what Hong Kong is today,’ he comments.

Having said this, the practice’s Cybertecture Academy has secured local partners in the social housing market in Cape Town in the southern township of Masipumelele. Plans are progressing well to deliver OPOD units to this township; a low-lying, sub-economic habitat that is beset with disasters, including runaway shack fires and winter flooding.

Should this pilot project work, it could provide a viable option for the rapid erection of quality and sturdy dwelling units in South Africa’s inner cities.

Aluminium upcycled – space-age concepts for compact housing

Other notable developments include the ALPOD, a dwelling fabricated from recycled aluminium beverage cans and other storage containers, yielding a living space of up to 42m2.

These space-age looking abodes take only two hours to be relocated from factory to site and lend themselves to highly adaptable on-demand driven architecture. They are attached to and can be moved around the core of a building.

Phase 3 of Law’s ALPOD project will include a contemplated delivery by drone onto site, to avoid the impacts of fossil fuel delivery by heavy road vehicles. Although a while from implementation, it does serve to illustrate the incredible foresight of this highly progressive architectural practice.

James Law Cybertecture is a registered Architecture Practice with the Royal Institute of Architects and Hong Kong Institute of Architects.

Next-generation multi-stage pump

Photo by Grundfos

The new generation of the world’s most modular pump range will significantly move the limits for inline multi-stage pumps. The new generation multi-stage pump from the CR range from Grundfos will increase efficiency and maximum working pressure while almost doubling maximum flow to 320m3/h.

The new generation, which will also introduce three extra-large flow sizes, is based on extensive research, development and testing of new hydraulic designs and engineered using state-of-the-art production methods – including a fully automated and flexible production line.

‘The new CR will significantly move the limits for energy efficiency, which is extra-important when you are working with large pumps.

The increase to maximum working pressure and flow will also mean that the new generation can be used even more widely. Engineers working with the new CR will literally have millions of customised solutions available to them’, explains Niren Rohanlal, Lead Business Development Manager at Grundfos, Sub-Saharan Africa.

The new 40 bar standard working pressure is ideally suited for applications like filtration, reverse osmosis and boiler feed. And with its increased 320m3/h flow capacity, the CR will even be able to take on high-flow applications, such as large waterworks which have until now been served by other pump designs. volume 8 | issue 3 www.tobuild.co.za

PROMISING PRODUCTS EDITOR’S CHOICE

Howard SunShield combines UV inhibitors along with a unique blend of carnauba wax, beeswax and orange oil to enhance the natural beauty and depth of grain in indoor or outdoor wood furniture.

This distinctly blended product effectively penetrates and replenishes natural oils in the wood (teak). SunShield should be used regularly, or whenever the furniture looks faded or dry.

SunShield with UV inhibitor is designed to protect both the wood finish and wood colour from sun fade. Some indoor antiques or wood furniture exposed to sunlight through a glass window, both directly and indirectly, can quickly lose colour, fade or lighten. SunShield with UV inhibitor greatly reduces sun damage and stops colour from fading when used regularly. Outdoors, SunShield is designed to condition and keep teak and other tropical hardwood furniture from drying, colour fade, and oxidation due to exposure to the sun. www.vermontsales.co.za

Phinda Homestead

Nicholas Plewman Architects – Phinda Homestead Photos by Nicholas Plewman

This edition of To Build features a Q&A with Nicholas Plewman, founder of Nicholas Plewman Architects, about his practice and a very special project they recently completed.

Tell us about your practice, its genre and approach

I founded Nicholas Plewman Architects several years ago, welding twin passions of design and the wilderness into a serendipitously symbiotic relationship. We simply care that development in the wilderness minimises its impact, appropriately sublimates itself to the bigger picture of sustainability and preferably creates an aesthetic tribute to its environment.

Tell us about your most recent project, Phinda Homestead

Phinda Homestead is built for AndBeyond, the leading African Safari Company, as a sole-use villa on the famous Phinda Game Reserve in northern KwaZulu-Natal. This renowned game reserve is part of the much larger Munyawana Game Reserve.

The idea was to provide a smaller and more intimate, but also even more luxurious, safari experience. Although large enough to volume 8 | issue 3 www.tobuild.co.za

accommodate independent travellers, Phinda Homestead is more likely to be booked for large families or small groups.

Were there any special inputs from anyone else?

Projects of this kind always involve a huge number of contributions, many of which go unheralded.

I would single out the Quantity Surveyor, Braam Alberts, as someone seldom credited but whose unique knowledge of building in remote places and contribution to keeping a relatively complex project on budget, cannot be underestimated.

What was the client’s brief?

Phinda Homestead replaced a previous homestead which had burned down. The client was anxious that the previous, very intimate relationship with the surrounding bush (some of which had also been consumed in the fire) be maintained.

Did you incorporate any ‘green’ innovations or special features?

The property is not fenced and wild animals can come and go. One of the guest highlights of the earlier building was elephants drinking regularly from the swimming pool. We were asked to volume 8 | issue 3 www.tobuild.co.za

Nicholas Plewman Architects’ ethos:

Bisate Gorilla Lodge, Rwanda

Jibali Ridge, Tanzania

Did you model the concept on any international projects?

No, not really. We used a couple of intrinsically vernacular ideas such as a very deep veranda for its obvious climatic good sense, assembled the building around a circular ‘farm reservoir’ and then explored the textures of rural KwaZulu-Natal, including mud walls, rammed earth, reeds and old sleeper timber herringboned to represent the reed mat weaving tradition.

Other projects

Nick tells To Build that his firm has recently been very lucky to have a couple of projects well received internationally. These include: • Bisate Gorilla Lodge in Rwanda for Wilderness

Safaris, which won several hospitality and design awards.

• Jabali Ridge in Ruaha, Tanzania, for Asilia which won ‘Best new hotel design’ at the 2018 ‘We are Africa’ awards.

• Sandibe Lodge in the Okavango Delta for Andbeyond. which won several hospitality awards and a GIFA Merit Award.

• Mombo Camp for Wilderness Safaris, which opened this year and looks set to do well.

Bank HQ design unveiled Renderings by dhk

Capitec Bank has unveiled the design of its new head office in Technopark in Stellenbosch. The business currently operates from multiple buildings in scattered locations in the same business park and has therefore decided to consolidate its offices into one building. The office will be custom-designed and owned by the company, thus increasing operational efficiencies.

Leading South African architecture studio, dhk, designed the building whilst considering Capitec’s current occupancy and planned growth.

The new building will be situated on two vacant and adjacent plots of land on the north-west edge of Technopark and will accommodate up to 21 500m2 of space. A number of key concepts have been considered, namely, the identity of the brand, internal flow and green initiatives such as water saving, energy saving and air quality.

Well known architectural practice, dhk, has designed a single three-storey building with a wide open-plan floor plate that ‘loops’ around a central triple-volume atrium. The loop adopts a fluid curvilinear form that shifts along its length, capitalising on the property’s 360-degree views. The floor plates are connected across the atrium by a series of feature bridges and staircases to promote interactivity between departments. The façade of the building was developed to accentuate the linear volume 8 | issue 3 www.tobuild.co.za

looped form with a simple ribbon of fenestration that responds to the ever-changing orientation of the building.

Looking to the future and considering the dynamic nature of the business, the interior uses best practice in modern workplace design. The building will enable a high level of interaction amongst business units whilst providing flexibility, adaptability and agility. In addition to workstations, the office will include a central canteen, coffee stations and a Capitec Bank branch.

A parking area has also been designed which will be housed in a separate structure.

Director at dhk and lead architect on the project, Peter Stokes, says: ‘Capitec encouraged input from the architects and interior designers to incorporate the latest workplace trends. To future-proof the design of the building, a flexible and agile approach was taken. The flow within the building supports a high degree of interaction and collaboration between business units and the executives.’

According to Derick Henstra, Executive Chairman at dhk: ‘Capitec is one of the most progressive and exciting companies in South Africa. We are

40

delighted to have been the architects chosen to design their new headquarters.’

Simple and sophisticated in its design with light, open spaces, the building will facilitate departmental and executive interactivity and ultimately efficiency. Capitec’s head office is set to be completed in February 2020. * dhk celebrates its 20 years in business this year.

During this time, it has grown into a multi-discipline practice that has embraced the digital world.

To Build congratulates Derick Henstra and cofounders as well as staff on this achievement.

Practice profile: Conduit Interior PHOTOS BY GRANT JOHNSON

Grant Johnson founder of Conduit Interior

Conduit Interior is a professional interior design practice based in Cape Town. Headed up by Grant Johnson, who has 20 years’ commercial interior design experience, the aim is to keep focused and lean – literally, a boutique practice. Each designer has an opportunity to take ownership of a project and see it through every stage, from client brief to project handover.

Johnson tells To Build that he set up Conduit Interior with the intention that the practice would be more hands-on, from start to finish, than traditional large practices. He believes this leads to more successful results where each interior is 100% tailored to each client.

‘We’ve been fortunate enough to work on projects throughout South Africa in Cape Town, Johannesburg, Pretoria, Durban, in the KZN Midlands, as well as projects in Africa (Kenya & Tanzania) and Europe. Our business model is built on relationships and word-of-mouth and part of this is that our clients often ask us to look at their national and international footprint,’ he says.

Conduit Interior’s primary focus is designing office space for corporates.

‘Clients are realising that today’s office spaces form a huge part of their employee value proposition and are vital for staff attraction and retention. Employees are no longer satisfied with run-of-the-mill workspaces; they want to feel like they are part of an organisation that is going places and will job-hop in search of their ideal environment until they find something that engages them fully for a significant part of their lives where they feel at the centre,’ says Johnson.

Project Korbicom

Korbicom is a leading developer of software solutions for the South African and international markets, responsible for business-efficiency products. It strives to attract, retain and support the best developer talent in a very competitive environment. Their new, creative and vibrant environment that fosters innovation was designed by Conduit Interior.

Breakaway spaces are provided for creative workshops and think-tank sessions. Focus rooms are provided as a getaway from the open-plan environment for concentrated work or private phone calls. The multitude of common areas enable free-flowing communication across departments in natural ways as well as supporting company-wide gatherings. The meeting rooms are provided in various sizes and are technology-centric to facilitate discussion and debate with global teams.

The interior inspires team members to want to come to work and spend time in their new and stimulating surroundings, as well as inspiring the most talented of new recruits to join Korbicom and be part of the company.

In the words of the client: ‘Our industry is competitive and cultivating an environment that

Conduit have delivered something truly exceptional – a vibrant, contemporary showpiece as well as a genuine source of improved workforce productivity. Their passion, creativity and dedication made all the difference for us.’

‘Each client has specific needs in terms of physical space. That’s the easy part but looking beyond this and asking the right questions to really understand who they are as a company and the goals that they aspire to, is one of the bigger and most important challenges. The space itself becomes the 3D embodiment of who they are,’ says Johnson.

‘Hence, it’s easy to give a client what they want, but to give them what they don’t yet realise that they need is where a great designer stands apart,’ he adds.

Project Property24

Property24 the South African property website, is passionate about helping people find their perfect home. They required a new head office space that reflected their fresh, energetic, dot.com brand, whilst still maintaining the highest levels of practical functionality for this high-end technology based company.

‘Conduit Interior successfully delivered on this brief by playfully juxtaposing traditional propertyrelated elements against a colourful modern interior, all the time ensuring that the client’s operational brief was met and that best practices were implemented,’ Johnson explains.

The main boardroom was designed as a modern take on a traditional front room, complete with a “Property24” traditional front door, a fireplaceshaped audio-visual unit, glazed vinyls reminiscent of Victorian balustrades and framed internet icons in lieu of family portraits.

The multitude of developer team rooms were each given their own character and identity with brightly painted Bo-Kaap style terrace doors, each with its own unique hand sourced vintage ironmongery. Clusters of street furniture were also incorporated to create non-corporate break out spaces.

Conduit Interior successfully created a space that truly embodies who Property24 is and what they do.

In Property 24’s own words: ‘We proudly have an office space that inspires us to come to work every day.’

Menlyn Maine evolves further Photos by Abland© Leon Swart, renderings by Barloworld

A leading property developer of over 30 years hosted a sod-turning event in September for the development of premium A-grade office space uniquely situated above a planned new Barloworld Motor Retail Toyota dealership.

Menlyn Maine Towers will form the tallest building inside the Menlyn Maine precinct, set to become Africa’s first green city based on new urbanism principles. Menlyn Maine partnered with the Clinton Foundation Climate Positive Development Programme to establish a roadmap towards achieving carbon neutrality in the South African environment.

To become climate positive and achieve net carbon negative outcomes, development partners of the programme can earn climate positive credits by sequestering emissions on-site and abating emissions from surrounding communities.

The mega development was initially planned to comprise a total of 315 000m2 of gross lettable area. Amenities such as restaurants, food shops, fashion outlets, health, banking and entertainment facilities are all within walking distance.

The first of its kind in South Africa

The development of Menlyn Maine Towers by Abland is in partnership with Tadvest, Namib Gate and Barloworld Motor Retail. Located in Pretoria East, the scheme will boast a proposed 4-Star Green Rating with Green Building Council accreditation.

The building area will consist of a 16 000m2 dealership with 12 000m2 premium A-grade office space above, creating 15 floors in total with potential for roof-top or penthouse offices also. The Barloworld Toyota Menlyn dealership is envisaged to trade by August 2019 while the offices are envisaged to trade by mid-February 2020.

‘We are very excited about this project. Not only will it be the first of its kind in South Africa where you have a dealership with premium A-grade offices above it, but it will be an incredibly efficient and green building. Additionally, the support from the Menlyn Maine consortium has been very encouraging and this, coupled with its location and design, makes us very confident in the scheme’s success,’ says Grant Silverman, Marketing and Leasing Director at Abland.

Ideally located along Corobay Avenue in Menlyn, Pretoria, the scheme is situated opposite the popular retail heart of Menlyn Maine, providing occupants of the Towers with access to a range of amenities from hotels and gyms to residential units.

Recent infrastructure upgrades also ensure that motorists have easy access from both the Atterbury and Garsfontein off-ramps from the N1 freeway.

Barloworld Motor Retail has a long relationship with Abland. ‘We are very excited to venture into this new initiative and we are looking forward to welcoming our customers to this new state of the art dealership in the future,’ comments Roland Egger, Chief Executive of Barloworld Motor Retail.

A clear visual distinction entices the look of two separate entities

Designed with a modern eye, the offices will be enveloped by a seamless glass façade created under a unitised system. Strikingly, while the scheme may be

just one building, there will be a clear visual distinction between the dealership and office components, enticing the look of two separate entities.

‘With this building we have designed and created premium commercial office space and a prestigious new home for Menlyn Toyota in an iconic and affordable building seen in the Menlyn and Pretoria context,’ explains Frits Schuite, Director of Boogertman and Partners, the architects behind the design.

‘The dealership will have a double-volume glazed façade showroom facing Corobay Avenue. Prominent individual entrances are provided for the dealership and office building. Activity is created on the glazed façade of the office building by introducing patios on the office floors with matching ventilation openings

on the four parking deck levels, and subtle variances in the tint colour of the thermal performance glass panels used in the unitised glazing system.

‘Facet lines are highlighted at night with LED strip lighting installed in the glazed façade. The office floors are designed to accommodate large single as well as multi-tenanted options with easy access from the ground floor entrance, visitors parking area and the parking floors via four elevators.”

A critical factor in the building is its sustainable energy use. Achieved through double glazing and thermal storage, water harvesting and energy efficient electrical installations, the building will be truly energy efficient. Notably, the dealership will also use water recycling processes allowing up to 75% of water to be reused.

The 7 commandments of property development An independent article by Wynand Tromp, architect

Whether you aspire to be a property developer, or whether you are a seasoned veteran, one thing is for sure: You have, or you will make some serious mistakes along the way.

Property development is no easy venture, and the pitfalls are spread far and wide. Of course it would be, otherwise everyone would do it. They say that in life the higher the risk, the greater the reward, but the idea is to minimise the risk by at least taking care of the things that are within your control. This is important as along the way you’ll find that there are countless obstacles over which you have no control.

1. Know thy neighbour(hood)

More often than anyone wants to admit, property developers simply buy in the wrong neighbourhood.

Albeit admirable, their vision clouds their judgement and they make an offer on a piece of land or a run-down building in a shoddy neighbourhood. By doing this, the project might as well be pronounced dead even before it has begun. If no one wants to live, eat, work or learn in that region, then you should probably not be buying into it. There is the exception of districts undergoing urban renewal but check your city’s Urban Development Framework (UDF) to make sure that the property falls within that zone. If it does, be sure to have the patience to wait for that tide to turn because urban renewal does most certainly not happen overnight.

If you’ve taken the plunge and you now own the property, step number two is to get to know your neighbours. Get them involved. Get them talking.

They have more power than you might think and one or two disgruntled neighbours could make your life very difficult. Such an extended battle could prolong your project timeframe, eating into your profit by the tick of the clock.

Most people tend to be open to a change in their surroundings if they feel they have somehow been involved and considered in the decision-making process.

46

2. Preserve thy riches

Chances are you will love your project more than anyone else. Like a mother will never admit to the flaws in her baby, you will be too subjective to accept the failings in yours. This is a dangerous mindset for a developer to have. You most probably love the property so much that you might underestimate the cost of refurbishing it. You might also overestimate how much you might be able to sell it for, upon completion.

Somehow, you need to stay objective. You need to find a way to not fall head over heels in love with your project. The saying “love is blind” is not just related to relationships. You need to join hands with an architect or other property expert that shares your passion and understands your vision, but one who can still guide you and keep you grounded.

Your architect will be able to assimilate your dreams with reality. He will be able to create design solutions which represent your aspirations without breaking the bank. Most architects understand the notion of “low input, high yield”.

3. Prepare thy path

You need to plan, plan, plan. Every inch of every corner of every aspect. No matter how dreary or tedious this is going to be, there is never a good excuse for ignoring due diligence. This is a critical step. If you are still exploring how to get started in property development, keep in mind that during your initial projects you should consider either calling in a qualified expert to handle this part of the process or you should undertake a property development course.

The money is well spent because you uncover hidden problems and pitfalls well before you commit to the project.

4. Choose thy flock wisely

In nature, a pride of lions will expel an injured or weaker member. The reason for this is that any group is only as strong as its weakest link. As a developer you need to have cognisance of the fact that by aligning yourself with an inadequate professional you could put your entire project in jeopardy. In property development you don’t get three life lines. You get one shot and you unequivocally have to get it right the first time if you want to hit the jackpot.

For you to get it right the first time you need to get skilled professionals on board that can strengthen your weaknesses. These professionals can guide you and advise you through the potholes.

Whether it’s the architect, the quantity surveyor, the town planner, the contractor or the legal advisor, you need to make sure that the team members are the best in their different fields; individuals you can trust.

You don’t necessarily have to appoint the largest and most expensive firms, but rather consider the professionals that will give your project their full attention. Remember that the larger firms put their staff on your projects, whereas the director of the smaller firms will be the one to look after your interests.

5. Appoint thy a reliable builder

If a development project is seen as an engine, the contractor could be considered to be the oil. The wrong oil would be catastrophic for that engine. As a developer it is of vital importance for you to appoint the right contractor and the right contractor is almost never the most affordable one.

As with the architect or the project manager, trying to save on costs by appointing the more affordable contractor could lead to vast expenditure later down the line. It all comes down to profit margin but trying to cut your expenses by appointing the more affordable contractor is not the way to go.

Rather spend a little more and have the peace of mind that your contractor won’t walk off site midway through, leaving you with an unfinished building and in the dreadful position to have to go out on tender again. This will reduce your profit exponentially and could even turn your profit into a loss.

6. Contemplate thy grounds carefully

The chances of you finding a site that is not included in some or other municipal bylaw zone is zero to

none. Any site located within an urban settlement has prescribed restrictive conditions which any developer has to adhere to. You need to check these restrictions before purchasing the site.

Your dream of a high-rise is most likely not going to be realised on a site where a height restriction of two or three floors is applicable. You need to ensure that your vision conforms with whatever the legal or regulatory complications of the site is.

Your chosen architect will be able to advise you about these conditions. If you have a close relationship with your architect, ask him or her to accompany you during your search for possible development land. Most architects are enthusiastic and appreciate being included from the very beginning. This is in fact where a project kicks-off. If the architect knows the site as well as you they will be in a better position to translate your vision into a viable project.

7. Focus thy attention on thy laws

The importance of the legalities around property acquisitions and development are too often underrated. Although it might seem unrelated to a degree, this aspect can severely affect the process when things go wrong. It’s good to remember that everyone is happy-go-lucky until someone is not happy anymore.

It’s at this point where you need to have sufficient paperwork in place to cover you against possible claims.

It might be a tedious and costly process but be sure to involve a legal export from the outset to take care of your option agreements, building contracts, pre-lease agreements and joint venture agreements, to name a few.

Align yourself with the right professionals

In conclusion, property development is a thrilling and exciting venture, but things can go horribly wrong. As a property developer following these basic directives could safeguard you to a certain extent. The most important thing about these guidelines is that you shouldn’t attempt to do this on your own. It’s impossible for one person to know everything, so by aligning yourself with the right professionals sooner rather than later, is your key to success.

The sooner you get the correct professionals involved, the better your chances of making it big.

The power of the group is nowhere more visible than with property development. volume 8 | issue 3 www.tobuild.co.za

Opinion: The right healthcare for Africa WORDS BY Laura Swanepoel, WSP in Africa Photo by © Production Multimédia du CHUM

Eliminating barriers and ultimately increasing access to quality health services for all, is a key pillar that requires significant focus if the aspirations laid out in the Agenda 2063 are to be achieved. It is also crucial if a prosperous future of inclusive and sustainable growth, where all African people have a high standard of living, quality of life, sound health and well-being, is to be realised.

‘There is no doubt that improving access to healthcare in Africa is a massive task. However, when it comes to the development of new facilities, part of the challenge stems from the many remote and rural areas that require these services, as well as the high costs generally associated with such projects,’ says Laura Swanepoel, Head of Healthcare, Building Services, WSP in Africa.

Swanepoel suggests that learning from global trends and adapting these to suit African conditions may be the key to building successful networks of healthcare infrastructure and medical facilities across the continent.

‘What the global trends teach us is that when building healthcare facilities, we must view these projects more holistically; considering not just design and delivery, but also whether the development is future-ready,’ adds Swanepoel.

Swanepoel shares her views on adoption and design principles that are making waves globally, and what these mean for future-ready healthcare in Africa.

Digitally driven healthcare services

Technological advances and the digitalisation of the healthcare industry are changing hospital design and planning; not to mention defining new approaches to patient care and administration.

Patients armed with information about their conditions are already informed consumers of clinical care, rather than passive recipients. It is therefore believed that patients will increasingly want to access services on smartphones and mobile devices.

WSP suggests that healthcare industries are being disrupted by widespread adoption of digital technologies, including increased connectivity, cloud computing, Internet of Things (IoT), Big Data and analytics-driven insights, collaboration tools and continued advancements in robotics and artificial intelligence (AI).

Globally and in Africa, there is already evidence of the effectiveness of wearable technology being used by medical professionals and medical aid volume 8 | issue 3 www.tobuild.co.za

2018/10/21 8:16 PM

Professions ENGINEERS providers to, for instance, advance patient care or customise insurance cover. Taking this a step further, WSP is seeing AI-powered systems at the forefront of patient care which can analyse data from sensors to provide continual or on-demand monitoring of conditions.

Adopting these kinds of technology opens new conversations around tele-medicine in that machines can now be used to screen all symptoms and provide preliminary diagnosis to deduce 90% of primary medical issues. In instances where health issues can’t be diagnosed, patients can be referred to a secondary facility in more urban areas.

With the addition of collaboration tools such as video conferencing, advanced high-tech solutions such as immersive telepresence, or consumer applications such as Skype or WhatsApp - doctors and specialists housed together in technologically enabled hubs will be able to reach, diagnose and treat patients wherever they are. Drones can then be used to disperse and deliver medicine and emergency medical supplies and any prescription, emergency or after-care can, for example, be administered by qualified nurses onsite at the clinic or medical centre.

Swanepoel believes that adoption of such technology trends offers immense opportunity to expand the reach of healthcare services, even to remote and rural Africa.

High performance building design

Globally there is also a continuous drive for efficiency and cost reduction, as well as increasing need for resilience to climate change and future energy and water scarcity. There is also a growing understanding that the environment in which patients are treated and cared for is a significant contributing factor to the healing process. Patient-centric design is therefore a key ingredient in a successful healthcare facility.

‘If we look at healthcare centres being built worldwide, there are a number of innovative architectural elements and sustainable design principles being incorporated. In Africa, there are some Government-led and private hospital group projects that are adopting these principles to create world-class hospitals,’ says Swanepoel.

‘In the commercial property space, building for efficiency, sustainability and climate change resistance has already been proven to boast significant return on investment. Added to this, in remote corners of Africa there are limitations on basic service infrastructure, including water and power, to contend with. As such, there is much

50

evidence to support the value of incorporating sustainability best practice and renewable energy solutions to improve the quality of hospital design.

Moving away from the principle of big concrete blocks that have a surgical and clinical feel, to instead create well-designed, functional spaces that are patient-centric, is both economically and sustainably sound,’ she adds.

New approach to delivering healthcare to rural Africa

Swanepoel believes there is definite scope in Africa but that high-tech and high-performance hospitals that deliver state-of-the-art care shouldn’t be the sole focus.

‘In Africa, there are many remote and rural areas that are well populated, but where access to healthcare is severely limited or entirely lacking.

In such cases, it may be better to adopt a more decentralised approach to healthcare that delivers services to a larger number of smaller facilities.’

One growing European trend is the move away from traditional mega hospitals towards more day clinics, which are smaller and more specialised.

‘This approach offers significant opportunities in Africa where more medical centres can be built with the aim of providing highly efficient delivery of core healthcare services for people living in remote areas,’ says Swanepoel.

Key to the success of such an approach will depend on prioritising spending on specialised medical centres and finding the most cost-effective and efficient manner to roll out day clinics in a networked series, across wider geographic areas.

Swanepoel indicates that there are already examples in Africa of prefabricated solutions for day clinics.

‘Such solutions include high performing, insulated, fire resistant, modular wall systems. These are easy to assemble and fully kitted to ensure they meet all the necessary hygiene requirements for the health codes. With these prefabricated solutions we can come up with a standardised design, as well as blueprints for any ancillary buildings, which can significantly assist in managing development cost, delivery and quality assurance,’ she explains.

‘There are many lessons to be found in studying global trends in healthcare infrastructure. Adopting a nuanced approach to the medical and hospital facilities we are building in Africa will make a massive, positive impact on the delivery of health services that are suited to the communities they will serve,’ Swanepoel concludes.

Blame bad attitudes

By Professor Amanda Gouws, published under a Creative Commons Licence per The Conversation, Africa

A leading academic argues that female professionals should not be held to blame for leaving fields like engineering. Rather, the blame should be laid at the door of the bad attitudes they experience.

There are reasons why feminists use the slogan ‘the personal is political’, especially when men make arguments using the age-old idea that ‘biology is destiny’.

Manglin Pillay, the CEO of the South African Institution of Civil Engineering, recently resorted to these types of arguments about the dearth of women in engineering.

Citing research, Pillay essentially argued that women were better suited to care for children than to work in the Science Technology Engineering and Maths (STEM) field. He said this explains the underrepresentation of women in the engineering field.

He wrote that: ‘The fact that more men occupy high-profile executive posts is tremendous not because of gender but because of appetite for workload and extreme performance requirements at that level.’

He further noted that women do not occupy high positions in the engineering fields because they: ‘…choose to have the flexibility to dedicate themselves to more important enterprises like family and raising of children…’

The article caused an uproar. Pillay has since apologised for his sexism after an outcry from many women, including the Minister of Science and Technology, Mmamoloko Kubayi-Ngubane, also a woman.

Regardless of the apology, we need to understand what kinds of attitudes inform Pillay’s thinking. He is not alone in this thinking and an apology doesn’t mean that attitudes have changed.

And there is a chance that Pillay misused the research as experts in the field come to different conclusions.

Pillay’s arguments boiled down to blaming women for the fact that there are so few of them in engineering field.

This is nonsense.

The results of a study on the experiences women

52

face as engineers in the workplace in the US sheds light on factors that explain the situation. The study, published in Frontiers in Psychology in 2017, involved a sample of 1 464 women engineers who had left the field. It showed that their decision to leave jobs in the engineering field were related to a number of key factors.

Firstly, poor and unfair working conditions. This included inequitable compensation as well as inflexible work environments that make work-family balance difficult. Secondly, dissatisfaction with effective use of their math and science skills, and lastly the lack of recognition at work and adequate opportunities for advancement.

These findings show that work-life balance and the glass ceiling for women are indeed the problems – not a lack of ambition or a biological need to mother children.

The problem therefore is not with women, but with the workplace and fairness in the family. If companies attend to these problems, women will stay and progress.

The numbers tell a story

While reproductive rights apply to both men and women, pregnancy is often viewed only as a woman’s “problem”. It’s left to women to fight for maternity leave, often against incredible odds, given that many companies see it as a costly imposition.

Labour legislation in South Africa now provides for paid maternity leave; six weeks paid leave and a total of four months unpaid. But many companies adhere only to the prescribed minimum, and also often make it difficult for women to take this leave.

But research shows that companies that take a more generous approach reap the rewards.

Take the US experience. The 100 best companies in the US listed by Working Mother magazine shows that companies that offer up to 16 weeks of paid maternity leave have a much higher retention rate of women. And they have lower staff turnover.

ENGINEERING Professions

Accenture, a company that has doubled its maternity leave to 16 weeks, saw 40% fewer women leave the company within a year after the increase. KPMG increased its maternity leave from 8 to 18 weeks and its retention rate of women also increased. KPMG states that it is cheaper to pay an additional 10 weeks of leave and coaching for new parents than paying for a new staff member which is the equivalent of 78 weeks’ salary.

There is therefore a business case to be made for maternity leave. Young couples now look at what companies offer when it comes to childcare arrangements and those with good maternity leave policies are more attractive.

Flexitime is another important way of keeping women in certain professions and making it easier for them to combine childcare responsibilities with work. FORBES magazine calls flexible working conditions a non-negotiable for engineers.

How to retain women

Amanda Gouws is Professor of Political Science and SARChi Chair in Gender Politics at Stellenbosch University and receives funding from the National Research Foundation. She holds a PhD from the University of Illinois in Urbana-Champaign in the USA. Her fields of specialisation are South African Politics and Gender Politics and Political Behaviour. Her co-authored book with James Gibson from Washington University St Louis, Overcoming Intolerance in South Africa: Experiments in Democratic Persuasion (Cambridge University Press, 2003) was awarded the Alexander George Book Award for best book in Political Psychology in 2003. In 2004 she received the Rector’s Award for Excellence in Research.

She has published widely on issues in South African Politics and Gender Politics. In 2012 she received the award for Distinguished Women in Science from the Department of Science and Technology. She is a member of the Association of the Academy of Science of South Africa (ASSAF). She was a Commissioner with the South African Commission for Gender Equality until June 2014. Her edited book with Daiva Stasiulis “Gender and Multiculturalism: North/ South Perspectives appeared with Routledge in 2014. Her edited book with Joy Watson “Nasty Women Talk Back” that is an engagement with the global marches against Trump’s election as US President will appear in August 2018 with Imbali Press.

Important lessons can be learnt from successful companies that have achieved high retention rates of women and increased staff morale and productivity.

Apart from increasing paid maternity leave, these companies have successfully developed policies that support women when they return to work. They have done this by developing values that recognise the long-term gain of having women stay and move up the management ladder. But these values have to be modelled at the top management level, such as the position in which Pillay is an incumbent.

What shouldn’t be happening in 2018 is that men in Pillay’s position continue to send the message to women engineers that they can’t measure up because they are women.

Dune rehabilitation shapes up Photos by City of Cape Town

During summer months under prevailing south-easter wind conditions, a massive wall of beach sand traditionally advances up the Hout Bay Valley, engulfing bus shelters, municipal infrastructure and threatening to close Princess Street by covering it with sand.

As can be seen from the satellite image the mass of sand beyond the beach is large and very mobile.

Human development over the decades has put the physical environment at odds with property owners, residents and road users.

The Hout Bay Dune Rehabilitation Project is managed by the City of Cape Town’s Coastal Management Branch and covers approximately 70 000m2 of re-profiled, netted and planted dune, which has significantly reduced the accumulation of sand on City infrastructure and private properties.

According to Councillor Brett Herron, the City of Cape Town’s Mayoral Committee Member for Transport and Urban Development, the Hout Bay Dune Rehabilitation Project is in good shape.

Herron recently planted a Milkwood tree on the site which forms part of the successful Hout Bay Dune Rehabilitation Project.

Milkwood trees such as Sideroxylon Inerme were key elements in the stabilisation of dune fields along the coast, by nature itself. These and other vegetation binds the soil and provides food and shelter for many creatures. However, they volume 8 | issue 3 www.tobuild.co.za

The re-profiled dune comprises three areas, namely the fore-dune, buffer-dune and back-dune. Suitable dune vegetation has been planted according to the requirements for each dune area.

According to Herron, the Hout Bay Dune Rehabilitation Project is a fascinating initiative that looks at how we can manage the movement and migration of dunes. The profiling, wind netting and planting of dune-specific vegetation has assisted in restricting the movement of sand which has been a problem in this area for many years.

‘I am very pleased to see and hear about the success of this project; we are making progress possible to improve the lives of our residents and ensure the accessibility to the City’s infrastructure’, he said.

Stimulating employment

‘Another exciting aspect of this project is that it has also created employment opportunities for 10 workers who were selected from the local subcouncil’s jobseekers database. Through this project, local residents have been upskilled and have learned

56

about plant propagation and maintenance, sand management, wind net installation and maintenance, watering and team work,’ Herron explained.

Private sector involvement

Now that the project has been established, the City is compiling a Hout Bay Dune Maintenance Tender which will seek to appoint a contractor to maintain the Hout Bay Dune Rehabilitation Project for the next three years, i.e. to the end of June 2021.

During the first three-year maintenance period, the City’s Coastal Management Branch will assess and plan the maintenance requirements forward in perpetuity and how this is best undertaken. If the maintenance is discontinued, the project will fail and the City’s infrastructure will once again be impacted by wind-blown sand from the mobile dune system.

‘The project has made great progress and therefore we need to ensure that the good work continues on site and that local employment opportunities are available’ Herron concludes.

Concourt throws site safety a curved ball Photos by Gareth Griffiths Imaging, Matteo Paganelli/Unsplash and www.lawyersites.net

On 18 September 2018 the Constitutional Court of South Africa passed a landmark judgement in which it ruled that the personal use of marijuana is no longer a criminal offence.

In the ruling, Deputy Chief Justice Raymond Zondo delivered a unanimous judgment that the ban on private possession, consumption and private cultivation of dagga at home was unconstitutional.

Hence, Parliament was given two years to change sections of both the Drug Trafficking Act and the Medicine Controls Act after these sections were found constitutionally invalid. In the meantime, this means that individuals are now allowed to smoke marijuana privately in their own home and can privately cultivate their own marijuana plants.

According to the Citizen (29 September 2018) the South African Medical Association (SAMA) has expressed reservations about changes to the law.

SAMA said support structures were needed to curb the drug’s negative effects on society and to assist addicts. It is to make a submission to Parliament in this regard.

SAMA president, Mzukisi Grootboom, said the ruling ‘comes as the country faces a big problem of abuse of alcohol and illegal drugs.’ It is claimed by the SA Society of Psychiatrists’ (SASOP), however, that 9% of those who tried marijuana would become addicted to it, increasing to one in six when use started during adolescence.

Potential impact of the ruling on the construction industry In the light of this, Advocate of the High Court of SA, Bryan Hack and Member of the Cape Bar who has also served two terms as Acting Judge in the High Court, Cape Town Bench, muses over the potential impacts of this ruling on the construction industry.

‘I have over many years said (purely in jest of course) that Cape Town traffic moves much slower than its counterpart in Gauteng because Cape Town

drivers start their day with a drag of the medicinal weed. Generally, I have so intoned when I have sat behind a car at a traffic light which simply does not move when the light turns green. My jest might now become a reality.

‘I am of course discussing the recent Constitutional Court decision to declare the use of marijuana under certain circumstances to no longer be unlawful. This is not the place to discuss the ramifications and practical implementation and effect of the ruling. In brief, the court order will require Parliament to change the provisions of Section 4(b) and (5 (b) and part 111 of Schedule 2 of the Drugs and Drug Trafficking Act 140 of 1992 as well as section 22A(9) (a) (i) and Schedule 7 of the Medicines and Related Substances Control Act 101 of 1965. But, what I want to address is the fact that employers will now be confronted with the excuse for poor working performance because of the private use of a morning “spliff” which is perfectly lawful. Yes and no?

‘In the building industry, site safety has always been a major concern. The presence of any person on a site whose cognitive abilities are impaired because of using intoxicating substances is a danger and risk. Previously, when it came to marijuana, an

employer could simply rely on the fact that its use was illegal and therefore being under the influence or merely having evidence that it had been consumed was a crime and steps could accordingly be taken against anyone on site or at the workplace.

Alternative ways needed to discipline employees who arrive at work under the influence ‘It is no longer a crime to be under the influence of the chemical substances in marijuana which may impair the user’s cognitive abilities. Alternative ways will be needed to prevent or discipline employees who arrive at work under the influence.

‘It might very well be that the legislature will provide guidelines and parameters for what is going to be regarded as lawful and what not. I am referring to provisions regarding the quantity of marijuana that can legally be possessed or precisely what will be defined as “private” use. Until such legislation is enacted, however, employers will be well advised to amend disciplinary procedures and rules to ensure that the same sanctions apply to being under the influence of marijuana or its use at the work place as is the case for alcohol.

‘I think it is reasonable to say that in most instances it will not be difficult to determine that the work place is not a “private” place. But to avoid confusion, it should be expressly written into an

‘Furthermore, where circumstances justify it, with reference to safety and risk in the workplace, that provisions should also be included for drug testing.

Such tests must comply with the Employment Equity Act No 55 of 1998.

‘In simple terms, there must be clear guidelines in place that prohibit employees from using the now lawful substances in the workplace.’

QUANTITY SURVEYORS Professions

International CM standards to be adopted in SA? The online mouthpiece of the Association of South African Quantity Surveyors (ASAQS), the Weekend Property and Consruction News, reports that the association is working with a growing group of professional and not-for-profit organisations from around the world to develop and implement standards for benchmarking, measuring and reporting construction project costs.

The International Construction Measurement Standards (ICMS) is a new, high-level international standard that aims to provide greater global consistency in classifying, defining, measuring, analysing and presenting construction costs ASAQS EduTech Director, Karl Trusler, represents the ASAQS in the ICMS coalition. He says that a global standard in cost reporting will benefit South African quantity surveyors, developers and other professionals in the built environment in a number of ways.

Level playing fields

‘When there is global consistency in how the construction costs of a project are represented, investors and clients are able to compare apples with apples,’ explains Trusler. ‘Through the introduction of a standardised cost reporting template, the ICMS is succeeding in creating a common language for the global built environment.’

‘Regardless of where they are based, clients can use the ICMS as a guideline to determine where in the world they should develop their projects to achieve the best returns thanks to the consistency and benchmarking it provides. It has the potential to level the playing field globally,’ adds Trusler.

The way that construction project cost reporting has been presented to clients, developers and investors in the past can vary from country to country and even within countries. Adoption of the ICMS means that construction costs will be presented in the same way whether at a project, regional, state, national or international level.

‘The stand-out benefit is that real comparisons of construction projects can be made and these comparisons will guide more informed decision making. An increasing number of local quantity surveyors are becoming involved in projects across

our borders. To become and remain globally relevant, they should seek to do their reporting in an internationally standardised way. The ICMS speaks to this need,’ says Trusler.

Universal standard usage mooted in SA

ASAQS’ representative to the coalition, Trusler, is tasked with staying informed and connected on global developments related to the ICMS and providing feedback and suggestions from members to the coalition. When asked how widely the ICMS has been adopted in South Africa, Trusler explains that it is still very new and has not yet become the status quo.

‘Like any initiative in the built environment, there are early adopters, but the majority of South African professionals in the built environment are waiting to see what the uptake will be. While the larger multidisciplinary practices may adopt the ICMS quicker, the majority of smaller practices in South Africa would be more cautious. Basically, all practices make use of some form of a cost reporting system so to become ICMS compliant, they would need to align their reports to the ICMS cost reporting template.’

The ASAQS plans to encourage the adoption of the ICMS through education.

‘When people are informed and grasp the value of a concept, they become motivated, and before long through their own initiatives the concept gains momentum. Across the globe, the ICMS is beginning to gain momentum through the efforts of local organisations. Lobbying at government level is a priority because government adoption will go a long way towards cementing the ICMS as the national standard within countries,’ Trusler concludes.

Breaching the 4th Industrial Revolution Photos by Centurion Systems

Since the advent of the so-called Industrial Revolution around 1760, mechanised industry and widespread production have become the heart and soul of many an economy, including that of South Africa. Urban development is at an all-time high, with more and more industrial hubs being established in major cities and metropoles and pumping new life into communities, whether through shopping and entertainment facilities, job creation or infrastructure.

Networked society

We are now in the midst of what Spanish sociologist, Manuel Castells, termed “the networked society”; a new paradigm that sees society’s major economic activities centre on a degree of connectedness made possible by the deployment of Information and Communication Technologies (ICTs), of which mobile telephony is one example.

Some refer to it as the 4th Industrial Revolution.

According to Wikipedia, The Fourth Industrial Revolution (4IR) is the fourth major industrial era since the initial Industrial Revolution of the 18th century. It is characterised by a fusion of technologies that is blurring the lines between the physical, digital and biological spheres, collectively referred to as cyber-physical systems.

It is marked by emerging technology breakthroughs in a number of fields, including robotics, artificial intelligence, nanotechnology, quantum computing, biotechnology, the Internet of Things, the Industrial Internet of Things (IIoT),

64

fifth-generation wireless technologies (5G), additive manufacturing/3D printing and fully autonomous vehicles.

Klaus Schwab, the Executive Chairman of the World Economic Forum, has associated it with the “second machine age” in terms of the effects of digitisation and artificial intelligence (AI) on the global economy.

‘The underlying basis for 4IR lies in advances in communication and connectivity rather than technology. These technologies have great potential to continue to connect billions of more people to the web, drastically improve the efficiency of business and organisations and help regenerate the natural environment through better asset management,’ he says (ref: ‘The Fourth Industrial Revolution’ Klaus Schwab, Crown Publishing 2017).

Applications in automation and security

A leading South African access automation leader has used this technology to great effect as a sophisticated and robust security tool. Centurion Systems’ G-ULTRA wireless solution uses the GSM protocol to communicate with users’ mobile phones. It can be configured to send status notifications related to gate motors, electric fences, alarms systems, fluid levels and much more. The onboard outputs can also be used to remotely activate a vast array of electric appliances, from gate motors to lighting. Centurion’s new G-REMOTE mobile app, launched earlier this year to massive acclaim, greatly simplifies remote monitoring and control with single-touch activations and push notifications. The app is available for download from the Apple App Store and Google Play Store.

Case study: World-class climate control used Photos by Fourways Airconditioning

Over almost a quarter of a century, Atterbury has become renowned for its elegant architectural designs and high standards with regard to construction. So when it came to the building of its own head office at Club 2 building in Menlyn Pretoria, it was no surprise that very high criteria were set for the HVAC system.

With Atterbury’s own engineers working in conjunction with consulting engineers Axell, the HVAC design was done and the project put out to tender. The brief was that the systems needed to be reliable, energy-efficient and stylish. Installers Ar Azul Projects won the contract having specified Samsung’s DVM-S systems supplied by Fourways Airconditioning Pretoria. Fourways then came onboard, working closely with Ar Azul Projects.

‘Because of the very high standards required by Atterbury,’ states Fourways, ‘the original design underwent a number of revisions which we worked on along with Ar Azul Projects and Axell. For most of the 2000m² office space, which is also occupied by other tenants, Samsung’s attractive new 360° cassettes were specified. As they are available ex stock in black, they perfectly match the black racks mounted below the ceilings which carry electrical and internet cabling, aircon piping, drain pipes, etc.’

Six Samsung DVM-S heat recovery outdoor units were installed, along with some splits. 71 indoor units were used, mainly 360° cassettes, as well as Mini Cassettes and hideaway units.

Pretoria to be the best in the market in terms of speed of delivery and stockholding. They deliver stock in batches precisely when needed instead of everything all at once. And they’ve worked closely with us to provide technical advice whenever necessary,’ comment Ar Azul Projects.

Completed in October 2017, the Club 2 aircon installation was put to the test during Pretoria’s hot summer. When quizzed if there had been any comebacks from client, Ar Azul Projects’ technician remarked with a smile: ‘We had to set some controllers at 24 degrees instead of 23, but that was about all.’

Completed within a tight deadline, the Samsung DVM Club 2 HVAC project has proven to perfectly align with the high standards of excellence required

by Atterbury Holdings.

Minding the gap Photos by ROCA

A leading sanitaryware manufacturer demonstrates a toilet innovation now available in South Africa. The toilet offers a clean rim with no gap in which bacteria can thrive.

Helping to maximise hygiene levels in the bathroom or washroom, Roca has introduced its innovative CleanRim technology to the South African market.

‘With the CleanRim The Gap toilet there is simply nowhere for germs or bacteria to gather, while the toilet’s hidden fixations and sleek modern design combine to create an uncluttered, streamlined finish in any bathroom setting,’ says Kyle Turner from Luximo, the South African distributors of Roca products.

Easy cleaning

Thanks to the innovative rimless design, the CleanRim toilets can be cleaned quickly and thoroughly for optimum hygiene.

‘It can often be difficult to clean thoroughly under the rim of a standard toilet as the toilet brush and cleaning agent do not reach everywhere. The CleanRim rimless pan design deals with this issue, making all parts of the toilet pan easily accessible for easy cleaning and best-in-market sanitisation. volume 8 | issue 3 www.tobuild.co.za

“It can often be difficult to clean thoroughly under the rim of a standard toilet as the toilet brush and cleaning agent do not reach everywhere.”

When it is flushed, the total interior of the bowl is rinsed because of the splash-free flow of water in the toilet that reaches right up to the level directly below the rim,’ explains Turner.

Water management

While less water is used than with a standard single or dual-flush toilet, the innovative new toilet always produces a powerful flushing performance thanks to pioneering technology neatly hidden behind the scenes. This allows the flushing volume to be reduced and still produce outstanding flushing results that are also water-efficient – using just 4 litres for a full flush and 2 litres for half a flush.

The toilet comes with the option of soft-close or standard seats and covers and is available in floorstanding or wall-hung models. With the wall-hung toilet, not only is the pan itself simple to clean thanks to its rimless design, but the floor beneath and area surrounding the toilet can also be wiped clean with ease.

Designed by Antonio Bullo, Roca’s new toilet features modern and stylish lines and is the latest product in Roca’s popular collection of basins, toilets, furniture and baths.

The Gap collection offers a wide choice of basins, toilets, bidets, furniture and baths to appeal to each individual need and allows the desired bathroom space to be perfectly tailored to each taste and requirement. There are also three bidets available to perfectly complement all toilets, including floor standing, back-to-wall and wall-hung – all of which can also be installed with a soft- close or standard cover.

Roca’s specialist designer, Antonio Bullo, is a renowned industrial designer based in Venice and specialising in ceramics. He has won four gold medals at the Faenza International Ceramic Competition and two Design Plus awards at ISH Frankfurt.

BUILDING SYSTEMS DOORS & WINDOWS

Energy efficiency in windows Photos by Swartland

Choosing the most energy-efficient windows can end up saving you a small fortune over the long term, explains a spokesperson from a well-known window and door manufacturer that produces products in both wood and aluminium.

‘Windows are the thinnest point between the interior and exterior of your home. This is why it is so important to choose energy-efficient windows, such as those we produce, for your project,’ Cobus Lourens from Swartland tells To Build

SANS 10400 speaks

However, aside from the obvious financial benefit, installing energy-efficient windows is a legal necessity.

‘In South Africa, the SANS 10400 National Building Regulations have been amended in the form of the XA appendices to further enforce and regulate energy efficient practices in the built environment, with the long-term benefit of reducing overall energy consumption and CO2 emissions. By law, the windows you choose must be

74

SANS 10400-XA-compliant as a new build without compliant windows will not pass the building regulations and will be deemed unfit and hence, illegal,’ explains Lourens.

Swartland continuously tests its products to ensure that they are compliant with the National Building Regulations.

‘All Swartland’s windows are SANS 613 certified and compliant. They have all been tested for deflection, structural strength, water-resistance, air-tightness, operating forces and the best possible energy efficiency,’ Lourens adds.

Fenestration and energy efficiency

There is a lot of jargon involved in fenestration and energy efficiency, however, there are two terms that you will hear over and over again which will help

volume 8 | issue 3 www.tobuild.co.za

063-098_Building Systems.indd 74

2018/10/21 8:31 PM

DOORS & WINDOWS BUILDING SYSTEMS you make a good decision – these are R-values and U-values. Lourens offers a simple explanation for both: • R-value measures a window’s resistance to heat flow and as such, the higher the R-value, the better.

• U-value measures how well the window prevents heat from escaping a building. The lower the U-value, the more efficient the window.

The material you choose makes a difference

It is imperative to look at what the window frame is made from, says Lourens.

‘There are a variety of materials currently on the market, including vinyl, steel, aluminium and wood. Each material boasts its own set of positive and negative aspects, but the two most popular materials for energy-efficient window frames are without a doubt wood and aluminium.’

Here, Lourens outlines the pros and cons of each of these materials: • Timber windows, such as Swartland’s timber window frames, offer the best insulation value and the highest cradle-to-grave environmentallyfriendly credentials. The rich and warm aesthetics of timber also makes them visually attractive.

However, they do require a little more upkeep than other materials.

• Aluminium windows, such as Swartland’s KENZO range, may not be the top-performing material in terms of heat transfer and loss, however, with slight adjustments in your glass choice you can still create a good energy-saving window.

Aluminium is a strong material that requires hardly any maintenance. Also, since aluminium is so strong, you can make window frames with exceptionally thin profiles, allowing for maximum glazing and views to the outdoors.

The implications of SANS 10400 XA –

by AAAMSA

According to regulations, to contribute to the reduction of greenhouse gases, buildings and extensions to buildings for which plans and specifications are to be drawn and submitted in terms of the Act must be designed and constructed so that they: • are capable of using energy efficiently while fulfilling user needs in relation to vertical transport, if any • thermal comfort, lighting and hot water, or • have a building envelope and services which facilitate the efficient use of energy appropriate to their function and use, internal environment and geographical location.

Compliance with Regulation XA vests with the person registered in a professional category of registration in terms of one of the Councils of the professions identified in the Council for the Built Environment Act, 2000 (sub regulation A2(1)(g)) who must in terms of AZ4 comply with the requirements of the National Building Regulations. The above was published in Government Gazette #31084 dated 30 May 2008 effective 1 October 2008.

From the above it is abundantly clear that fenestration manufacturers and contractors are not responsible for compliance with Regulation XA and must follow the design as given by the appropriate registered professionals.

However, according to the Association of Architectural Aluminium Manufacturers of South Africa (AAAMSA), a worst case whole glazing element performance values calculation by a competent professional may be deviated from in the event that the fenestration contractor/ manufacturer can provide certification issued by the South African Fenestration and Insulation Energy Rating Authority (SAFIERA) under the AAAMSA Group. This certification will confirm the performance in respect of thermal as well as mechanical performance of the specified products.

This SAFIERA Certificate therefore provides confirmation that products comply with the requirements of SANS10400-N: Glazing and SANS 10400-XA: Energy Usage.

New electricity generator can benefit the poor Photos by City of Cape Town & Gareth Griffiths

To Build reports here on the launch of an innovative waste-to-energy converter, fueled by organic waste including agricultural waste, plant material, food waste and other organic materials. When fermented, these waste products produce usable methane and other by-products of fermentation which are combustible.

According to Cape Town Mayor, Patricia de Lille, Cape Town is a world leader in inclusive climate action that brings new opportunities to address inequality. Speaking at a press tour of the gas-toelectricity generator production facility she said: ‘I recently returned from San Francisco where leading cities from across the globe, including the City of Cape Town, signed an equity pledge to commit local governments to ensure climate action is used to achieve development, improve living conditions, reduce poverty and boost economic growth. Cape Town is one of 30 cities representing close to 100 million people across the world that has signed

an equity pledge that commits cities to inclusive climate action.’

The CEO of Sustain Power, Tobias Hobach, participated in the City’s funded master class and pre-incubation workshop series in 2017.

The City supports the South Africa Renewable Energy Business Incubator1 (Sarebi) to run these programmes to encourage local entrepreneurs to innovate and create jobs in the industry.

De Lille was speaking at Sustain Power’s premises in Epping where it is manufacturing containerised generators that convert biogas and landfill gas into electricity for heating or cooling.

‘It is encouraging to see that within a year Sustain Power is manufacturing their 500Kw BioGas CHP generators from their facility in Cape Town. The company has become the only local manufacturer of gas-to-power gensets in the country. This is a first for the South African economy and the energy sector,’ she said.

An encouraging sign is also the inter-disciplinary cooperation where the renewable energy company innovatively partnered with a Cape Town-based company, Unique Group, that in the past provided saturation dive support vessels to the fossil fuel industry but are now using their skills to produce infrastructure for clean energy.

But why does the City of Cape Town focus on providing support to the renewable energy sector?

According to De Lille, Sustain Power and many other companies supported by the incubation programmes show that climate change is not solely an environmental issue, but can be inextricably linked to eradicating poverty by growing the economy and jobs.

In addition, this particular business addresses four of twelve of the key metrics on the City of Cape Town’s Mayor’s Portfolio of Urban Sustainability.

Cape Town Mayor, Patricia de Lille, with the Sustain Power team on-site

1. It develops viable enterprises in the clean energy sector for the future sustainability of the City and its communities.

2. The generators burn and consume methane, thereby reducing the release of greenhouse gas into the atmosphere.

3. The company creates a way to convert landfill gas to electricity and heat, making it a resourceefficient energy source.

4. The new business creates economic opportunities and jobs.

According to the Mayor’s office, gas-to-power, wind and solar are all options the City is exploring.

Earlier this year the City announced a R12.7-million agreement with the US Trade and Development Agency to study the possibility of using natural gas.

Surely a crowning achievement for the City’s outgoing Mayor Patricia de Lille and her team!

The Square Shopping Centre Photos by Sika

Dawood Vawda, a well-known entrepreneur in the North-West of KZN has opened the Square Shopping Centre in Ladysmith, where his third Mica franchise will also be located. As the owner/developer of the Square Shopping Centre, he had a vested interested in the overall project and ensured premium products were used, both in the construction and finishing touches.

Sika has recently launched a brand-new tile adhesive range, including a porcelain adhesive product suitable for applying the porcelain tile finish to both walls and floors in the centre. Their regional manager, Mervyn Naidoo, was on site to offer sound advice on correct applications and products for the specified requirements. This is the largest tile adhesive project for Sika SA to date, completing a total of 11 880m² of floor and wall tile area in the mall.

SikaCeram-200 Porcelain tile adhesive was used for all floor tiles throughout the mall as well as the walls in the passages leading to the bathroom areas. It is a single component, pre-packed tile adhesive mortar, combining cement with selected grades of sand and synthetic polymers. It is easily mixed with water to produce a smooth, thixotropic tile adhesive for thin- or thick-bed application.

In addition to the interior finishes, the project also required waterproofing of the outside walkways and entrance. Cemflex (250lt), an acrylic based emulsion was the simple solution was chosen for its ease of application and efficacy. It improves the water resistance and adhesion of Portland cement-based composites, is watertight and has good abrasion resistance, ideal for the general wear and tear of foot traffic.

For minor patch repairs incorporated into the screed mix, Sika Latex® was the product chosen and is a synthetic rubber emulsion. The product is suitable for use in tropical and hot climates. It is known to have extremely good adhesion, reduced shrinkage, greater flexibility and excellent water resistance.

Sikalastic-560, one component, liquid applied waterproofing membrane, was specified to waterproof the flat roofs of the power station room.

Sikalastic-560 provides excellent adhesion on both

80

porous and non-porous substrates as well as on bituminous products, and since it is a completely seamless, fully bonded system, the risk of leaks due to overlap failures is negated. Combining the high performance of polyurethane dispersion with the familiar properties of an acrylic, co-elastic technology offers an unsurpassed performance compared to conventional acrylic dispersion; higher elastic and crack-bridging properties, faster drying times, higher UV resistance resulting in better colour stability and durability, as well as being environmentally-friendly with very low odour and Volatile Organic Compounds (VOC).

Sikaflex®PRO 3i, a one part moisture curing, elastic joint sealant was used to for the expansion joints of the floor in the interior section of the mall.

The product is a multipurpose floor joint sealant suitable for movement and connection joints in floors, joints in contact with potable water and indoor and outdoor applications for pedestrian and traffic area.

Glass-fibre reinforced gratings Photos by Vitaglass

A specialised manufacturer is reinforcing the trend toward maintenancefree, glass-fibre reinforced gratings.

Over the past few years a local engineering services company has seen a significant growth in demand for their Vitaglass range of glass-fibre reinforced products. This indicates a growing preference for maintenance-free construction materials in mining, industrial and construction projects.

According to Glen Pringle, Technical Director at Vital Engineering, the Vitaglass range fits extremely well into their product portfolio. Depending on the consulting engineer’s specifications, there is usually a requirement for glass-fibre reinforced grating hand railings and solid flooring.

‘The material offers clear advantages in terms of price, weight and zero maintenance requirements - without compromising on design or safety specifications,’ Pringle points out.

‘The inherent advantages of glass-fibre reinforced products are plentiful. It possesses good load-bearing strength at approximately half the weight and its corrosion-resistant and fire-retardant properties make this product particularly suitable in harsh or highly corrosive conditions, or in situations where potential sparking or fire could be a risk (such as in underground mining or at sea on an oil rig),’ he adds.

Another significant advantage is that component theft for the purpose of reselling (such as with copper) is eliminated in many instances. The company’s products may be produced in a wide variety of colours which can be applied for safety purposes such as colour-coded emergency walkways, but also for architectural and aesthetic considerations. An example of the latter is the

82

property development sector, where sun diffusers and burglar bars can be specified by the architects concerned and produced in colours which complement the building design.

Pringle emphasises that fibre reinforced products (gratings, hand railings, sections) are not a form of plastic and should not be perceived as such. They are a saturated glass-fibre reinforced resin product.

Although fibreglass is not recyclable, the production process is relatively clean and it is viewed as an environmentally-friendly product suited for applications in so-called ‘green’ buildings where a reduced carbon footprint is the objective.

From a manufacturing perspective, glass-fibre reinforced gratings can be either moulded or pultruded, a continuous process of manufacture featuring constant cross-sectioning of the material that results in a stronger material. Structural strength can also be improved by a ‘ribbed’ design for greater load-bearing properties at a lighter weight.

The material properties can further be adjusted by additives resulting in fire retardance, UV resistance, and differing composite characteristics.

To date, the suppliers glass fibre reinforced gratings have been used in a wide variety of projects and sectors, including mining (including mineral sands processing plants as well as underground and above-ground walkways, conveyer belts and more), petrochemical and power generation, to the food and beverage (breweries and wineries), architectural, aquaculture, maritime and offshore oil and gas sectors, to name but a few.

Durable gratings Photos by Andrew Mentis

Enhanced corrosion resistance is a priority for many specifiers and users of industrial floor gratings.

Rectagrid RS40 (40/40) floor grating by Andrew Mentis is manufactured in a world-class facility at Elandsfontein, Johannesburg, using a pressure locking system pioneered by Andrew Mentis.

Quality control during the manufacturing process ensures that close tolerances are maintained and that the round transversal bar fits tightly through the pierced bearer bar.

‘Our manufacturing process produces unquestionable locking characteristics, guaranteeing the structural integrity of the product and giving the customer absolute peace of mind,’ says Lance Quinlan, National Technical Sales Consultant at Andrew Mentis.

Rectagrid RS40 (40/40) is formed through a process of compressive pressure locking of bearer bars and transversals to form an exact pitch of 40mm x 40mm.

Quinlan says that to be considered “good”, floor grating elements need to meet certain nonnegotiable criteria.

‘The transversals must be positively and permanently locked to the bearer bars. There should be no cracks or crevices at intersections which could harbour corrosion and the locking method at the intersections should be designed to use the full depth of the bearer bar when calculating loads,’ he explains. ‘Finally, the grating panels should be flat, square and untwisted.’

84

Quinlan says that because the intersection locking is so positive and strong, it is not necessary to band the grating.

‘For that reason, we went a stage further and arranged for the panels to leave the rolling mill finished on half pitch all round. This means we can now lay panels adjacent to each other to maintain a perfectly patterned floor with no banding. This is known as the “open ended system”. However, if customers require banded grating, we have the facilities to accommodate this,’ he comments.

‘Rectagrid RS80 (80/40) is identical to RS40 (40/40) grating except that we simply omit every second bearer bar, giving an 80mm pitch bearer bar. However, it still has a 40mm pitch transversal.

Because RS80 (80/40) has only half the number of bearer bars, the permissible load it can carry is only 50% that of RS40 (40/04),’ he explains.

Manufactured locally from raw materials supplied

by Mittal, Rectagrid is a highly engineered product that has been successfully tested in the field.

German-based manufacturer, Miele, recently launched its new SmartLine range at a special evening for clients and media in Cape Town. To Build was there in force to check out the new range.

Popular chef, Sarah Graham of Sarah Graham’s Food Safari fame, expertly demonstrated the versatility of cooking on a sleek integrated range with a selection of recipes designed to test both the gas and induction cooking aspects of the system.

According to Mercia de Jager, Brand Manager at Miele, the heart and soul of the new appliance constellation is in many cases likely to be the 60cmwide induction hob with a countertop extractor, complemented with further modules that dock on either side.

‘With this basis to choose from, creativity knows no bounds, not least because two or more extractors can be integrated into a run of units,’ she says.

The epitome of sleek design, all SmartLine modules have a depth of 52cm; their frameless glass ceramic screen permits flush or surfacemounted installation and the touch controls

dubbed, SmartSelect, only become visible on the black ceramic screen when the appliance is in operation.

‘This underlines the aesthetic appearance and makes for congruency in design which makes SmartLine the ideal proposition in open-plan kitchens,’ says De Jager.

Induction cooking

According to Sarah Graham, who uses Miele’s products in her own kitchen: ‘The company has paid attention to a chef’s needs and has made cleaning as simple as possible for the user. A simple wipe during cooking removes all residue or splatter and does not interfere with the cooking settings. The smooth glass ceramic surface is particularly easy to clean, not least thanks to induction technology that does not heat up the glass screen itself and thereby prevents food from burning on to it. Indeed, SmartSelect controls feature a function that prevents any inadvertent changes to settings while cleaning the units.’

De Jager says that removable parts, such as the griddle, trivets on gas units and the stainless-steel grease filter box, are all dishwasher-proof.

However, it is the attached stainless-steel

induction griddle that really impresses. A source of safe heat and touchable, demonstrated when Sarah griddle cooked lamb steaks, is equally easy to clean.

Filtration

A huge plus of this range is the fact that extraction can be done via a horizontal extraction unit which sucks cooking vapours down and into a filtration unit inside the closet. Hence, no more bumping of the cook’s head compared to using a conventional hooded extraction unit. In addition, when using gas, a simple magnetic attachment between gas hob and extractor vent prevents flammables from being sucked down across the flame. Filters needs to be changed infrequently, about every three years, says Miele head of marketing, Liam Gawne.

All about choice

‘Customers can customise their hob ensemble and choose freely from induction hob, Teppan Yaki, gas ring, induction wok and countertop extractor.

Together, they form a cooking centre which, when mounted on a free standing unit, helps to breaks down the boundaries between kitchen and living space,’ adds De Jager. volume 8 | issue 3 www.tobuild.co.za

It’s all about the clip

Saflok 410 Clip

Photos by Safintra

Concealed fix roofing is the most sought after roofing system on the market, not only for its proven functionality even at very low slopes, but also for its durability and sustainability.

At the heart of the system’s performance is the design of the clip holding down the sheet and the integrity of the interface between clip and sheet.

The closer the sheet-to-clip interface and the stronger the clip holding it onto the substructure, the stronger the entire system.

Stronger clips needed for increasingly turbulent weather

Globally, weather patterns have become more violent and South Africa is no exception. With this in mind, Safintra South Africa has invested considerable resources in the engineering, design and manufacturing of stronger clips for its widely used Saflok system. In 2017, the company launched the re-engineered Saflok 700 clip and now unveils its new Saflok 410 Clip.

The new Saflok 410 clip has delivered outstanding results in wind uplift tests, making it the strongest clip on the South African market.

Central to all product innovations in concealed fix roofing is the ability of the clip to withstand the forces exerted by wind, the most common reason for system failure. Contrary to common understanding, it is not because the wind gets caught underneath the sheet and forces it off, but rather that a strong suction (negative pressure) is created over the outer surface of the roof sheet when the wind blows over the roof sheeting. This negative pressure lifts the sheet up and can succeed in physically forcing it off the clip.

Eaves and overhangs

Eaves and exposed overhangs are particularly vulnerable; at this point the roof endures a

combination of negative suction above the roof plus positive pressure caused by wind blowing up underneath the eave. The combination of these forces works together to try and disengage the sheet from the clip. For this reason, purlin spacings on the overhangs are reduced to increase the holddown intervals required to cater for the doubled wind forces it endures.

The most common failure point for a roof clip is the ‘Goose Neck’ which takes on the most pressure when high wind conditions are experienced, especially on the gables and eaves. It is essential for the clip to have a very sturdy Goose Neck for it to withstand increased wind loads. The new Saflok 410 clip has deeper embossing for rigidity to allow for greater hold-down capabilities.

Purlins

A tail has been added to the 410 clips to allow for an additional fastening point onto the purlin.

This increases its hold-down capabilities and also strengthens the anchor which engages with the centre rib of the sheets. The tail minimises rotation on the anchor of the clip, giving it more rigidity. It also ensures that the anchor will maintain its linear integrity during installation, preventing the clip from distortion.

The Saflok system has performed outstandingly on millions of square meters of roofing in Southern Africa and is setting the bar even higher to stay ahead of changes in climate conditions.

BUILDING SYSTEMS STEEL FEATURE

Cladding employ only the most skilled Photo by Gareth Griffiths Imaging WORDS By Dennis White

The South African Metal Cladding and Roofing Association caution the building industry to match the contractor used to the task at hand.

Whilst metal cladding is used on all types of buildings, from residential to industrial and everything in-between, the skills required to install a weatherproof envelope vary considerably with application.

When it comes to residential applications, aesthetics and attention to detail are paramount as the cladding is mostly viewed from a short distance.

Any imperfection, be it mechanical damage (dent or ragged edge), misalignment or badly installed flashing become all too obvious. Imperfections are less obvious on cladding with a matt and textured finish when compared with the conventional 30% gloss-coloured cladding. Hips, valleys and dormer windows are a common feature. Roof slopes range from 2° to 30° or more. In this application you need to employ only the most skilled roofer. Unfortunately, the installation is regularly undertaken by the builder or truss maker with shortcomings in the design and fitting of flashing invariably having to be patched with paint on membranes which are both unsightly (quickly fade to a different colour to that of the cladding) and expensive to maintain.

Mind the mortar

Another problem is the damage inflicted when plastering chimneys, behind parapets, etc. Metal cladding and mortar are not compatible; this type of damage can negate any warranty on the coating. The key is to complete these actions before the cladding is installed, failing which the cladding needs to be

Holdsport Warehouse, Chartwell Roofing, Kliplok 406, Clean COLORBOND® African White/Armour Grey

protected with a waterproof cover and duckboards.

Industrial applications require a contractor skilled in working at height with long lengths of both roof and side cladding. The fitting of bullnosed and pre-curved cladding require special skills as do the installation of insulating materials and in-plane rooflights.

Although most commercial applications are basically the same as industrial, some architectural features may require the specialist skills for residential applications.

Concealed-fix systems

Whilst the skills to install the generic pierced-fix corrugated and box rib cladding systems are universal, there are unique variations between the requirements for the different concealed-fix systems.

It is vitally important to confirm that a cladding contractor has received the necessary specialist training from the cladding profiler (manufacturer) to ensure optimum performance of a system.

Most reputable profilers provide a list of approved contractors for the installation of their systems.

As the industry is rife with unscrupulous contractors, we strongly recommend that you establish bona fide approval directly from the profiler, particularly if a performance warranty is required.

Honouring heritage approval In 2014 Lead Architects undertook a development masterplan of the Albini Mission situated in Ntshongweni in KZN for the Catholic Archdiocese.

Renowned construction company F Verbaan, roofing contractor GWR Roofing together with Use-it, suppliers of Rambrick bricks, have all become key contributors in the rebuilding and restoration of this AMAFA* site.

The 80-year-old church is receiving a restoration that is honouring its aesthetic appeal but enjoying a modern and rapid reconstruction approach following extensive community engagement and heritage approval.

The Ntshongweni mission station was born of a promise made by Fr Wagner in 1939 when he was serving for France in the Second World War. His promise was to achieve something significant as a thanksgiving for sparing his life should he survive the war. Following his release from service he returned to Ntshongweni in 1943 and true to his word, established a mission station with himself as the permanent priest to the original Albini Church which was built in 1938. He also established the Ntshongweni boarding school.

In 1970 Fr Wagner passed away but his legacy was continued by Fr J Codognes. The Mission was further developed to include a school and boarding

establishment. Today, key contributors such as Lead Architects, Verbaan Construction and GWR Roofing have the privilege of continuing this legacy by expanding Albini Church and preserving its aesthetic properties.

Planting the seed

Amanda Lead of Lead Architects is responsible for creating and designing the extension of the Albini Church. Morrissey Engineers and RMI Quantity Surveyors formed part of the professional team for this project.

‘A bigger church was required for this growing parish which currently only seats 90 people and is used mainly by the mission residents’, Lead reports. ‘The aim is to increase the space to hold a capacity of 450 people, which is indicative of the communities’ needs.’

Of the three concepts that were proposed by

Bringing it to reality

Responsible for converting the architectural vision to reality is local builder Verbaan Construction.

Purchasing manager Warren Verbaan explains: ‘Special consideration has to be given to the building to ensure that the original structure in its existing state is maintained and that existing fittings and finishes are restored.’

Materials that are considered structurally compromised are being replaced with the same or similar to those historically used. Special Rambricks which are manufactured using a compressed clay method are being used for the construction of this heritage site.

It was also agreed that community members will be involved in the building process. Other special considerations such as custom-made window frames built to maintain the unique original window shapes were also one of the challenges the teams faced. In the absence of lintels, these lightweight steel frames were also designed to support the Rambricks.

The church site requires utmost care to ensure that Lead Architects, Verbaan Construction and GWR Roofing complies with the original 1938 architectural and aesthetic appeal of the building.

Work on the site is progressing rapidly and completion of the current phase of the project was expected to be September 2018.

The cherry on top

The roof construction project is divided into two sections; a new section which comprises a steel structure with loose rafters bolted to the steel IPE, and the roof of the remains of the original church which comprises of prefabricated trusses.

‘Due to AMAFA specifications the roof installation has been challenging. The original building is not square nor is it level, even the original wall plate heights vary significantly,’ says Andrew Gove, industry roofing specialist and director at GWR Roofing.

‘Rafter-bearing trusses had to be designed and installed to counter these inconsistencies, as well as tie into a perfectly level and square new building, all the while maintaining a smooth transition between old and new with special consideration to the raked ceilings inside the church’, Gove adds.

Global Roofing Solutions generously supplied the roof sheeting coil at cost price, rolled the Victorianprofiled sheeting and delivered it all to site free of charge.

In addition to erecting the Albini Church roof and in line with its vision of creating growth and training opportunities, GWR Roofing assisted the Institute of Timber Construction by opening the site to an ITC training initiative that recently had inspectors from the National Home Builder Registration Council (NHBRC) learn the details of erecting and inspecting the installation of a timber roof structure.

Being a work-in-progress site, Naidoo was able showcase GWR Roofing’s work to explain the ITC good practice and standards to which GWR Roofing is held accountable. Bracing, installation of roof trusses and structure stability were topics that formed part of this practical training outing to the Albini church site.

The development and building teams agree that this project has been both challenging and stimulating. *Amafa is the Provincial heritage conservation agency for KwaZulu Natal, as appointed by the Premier of KZN.

Lead, the client has proceeded with the option that preserves as much of the original church structure as possible in the centre of the site. Part of the original building needed to be demolished to make way for the large extension, however, the footprint of the original building will be evident in the internal flooring, as different textured flooring. This forms a large enough space for priests to meet in an area that is considered to have historical and religious importance.

According to Lead, the most challenging aspect of the design was scale; adding a vast amount of space without dwarfing the existing church. The design and construction of the roof was the main contributor in eliminating this challenge. Consistent eave heights and manipulating the roof pitch ‘played the volume down’.

‘This is the main reason that the construction of the roof was so important to the success of the project. We are fortunate to have had such experienced contractors working on it – it looks incredible,’ says Lead.

39kg mirror with Mirrorfix-MS adhesive

Mirror-specific adhesives for large installations Photos by Den Braven

A high-quality mirror-specific adhesive was specified for the bonding of the mirrors at the ballet classroom at Curro Woodhill College in Pretoria recently.

Aluminium Window Specialists (AWS cc) who installed the nine floor-to-wall mirrors, each weighing 39kg, chose Den Braven Mirrorfix -MS because of its high strength and instant tack properties It is designed specifically for bonding mirrors as its composition means it will not erode the silver backing of a mirror. Based on hybrid technology, the cured adhesive forms a durable elastic rubber between the mirror and substrate to ensure the long-term successful bonding of any mirror onto most backgrounds. The elastic rubber formation of the adhesive ensures that the bond will not be broken due to differential movement that takes place between the mirror and the background onto which it is bonded.

The project was a joint venture between AWS, Den Braven Sealants and Glass Specifics who were confident that Mirrorfix-MS would instantly fix the heavy mirrors in place and were on site to assist Aluminium Window Specialists

How to apply the product

Mirrorfix-MS is applied using a professional applicator gun held at a 90° angle to the mirror, with the “v� of the nozzle facing upwards to maximise the area of contact. Extrusion of the adhesive is started 10mm away from the edge of the mirror and applied in

100

vertical strips (not blobs) 100mm apart. The vertical adhesive strip application allows for circulation of air behind the mirror to ensure the adhesive obtains full cure. Lift the mirror into place and push firmly against the mirror surface to ensure adequate bonding of the adhesive and the substrate.

Application tip

Blobs of adhesive applied to any substrate are not recommended as the blob cures from the outside inwards. If insufficient air passage is prevented, the blob may never fully cure in the centre. Horizontal adhesive stripes are also not recommended due to moisture and dust settlement which over time could erode the adhesive bond.

Mirrorfix-MS is suitable for use on wood, stone, concrete, plasterboard, tiles, steel, aluminium and good paintwork. It is free of isocyanates, solvents and silicones, is environmentally-friendly and conforms to Green Building Council of South Africa standards.

Promoting inclusive sustainable practices in micro-enterprises photoS by Gareth Griffiths Imaging AND CBA

The Clay Brick Association of South Africa (CBA), EcoMetrix Africa (EMA) and Partners for Innovation (PfI) have been commissioned to execute a three-year project co-sponsored by the European Union (EU) under the SWITCH Africa Green programme.

The CBA is a member-based industry association that creates awareness, shares knowledge and provides support and capacity-building related to the clay brick supply chain in South Africa.

‘The Switch Africa Green Project involves several integrated industry initiatives,’ reports CBA Executive Director, Mariana Lamont. ‘Knowledge is key to managing both environmental and socioeconomic sustainability. Our project plan includes

research, education and an exchange of ideas between formal and informal brick producers, as well as improving awareness of green building practices in the construction industry, government and home-owners.’

The formal clay brick sector is well regulated in terms of legislation and oversight and the CBA has driven numerous environmental awareness initiatives over the past 10 years. However, very little

“We face many challenges, particularly in funding materials and fuel, but we remain in business as we have a loyal following of customers who want our product over the cement block. These are mostly people that build their own houses” - Daniel Scheepers, informal clay brick producer, Phuthaditjaba.”

is known about the informal sector. This sub-sector – in excess of 2 000 micro-enterprises located in primarily rural areas – is not officially regulated or monitored.

The CBA has recognised a real need to better understand the informal sector and the challenges they face and is engaging with informal brickmakers to survey their practices and attitudes with regard to sustainability.

Findings

Fostering sustainable brickmaking micro-enterprises

Next steps

The informal sector plays a small but important role in supplying affordable, durable construction materials to local communities. Their operations consist of very small, traditional and, labour-intensive businesses using methods that use local natural resources inefficiently, which get depleted.

However, one Switch Africa Green Project initiative is to undertake education interventions that will reduce coal and water consumption, air pollution and waste. This will minimise the impact on communities by decreasing greenhouse gas emissions and nurturing local biodiversity.

The project team have been assisted by local Clay Brick Association members who are helping to identify informal brickmaking belts, provide interpreters and then test samples gathered in the field.

Initial findings are that there is almost no knowledge about sustainable consumption and production (SCP) practices and patterns. A common concern is sourcing and paying for fuel which is a major cost.

Education on energy efficient production methods, will not only improve resource use and air quality, it will also reduce cost so informal brickmakers are keen to learn.

Moving forward the CBA project team will develop a comprehensive database for future communication with the sector. They plan to develop information toolkits and training materials based on locallyrelevant best practices to raise awareness and build capacity.

Education materials will be a critical element in implementing a basic brick-making course designed to give the informal brick makers with the skills needed to produce more sustainably and profitably.

These informal entrepreneurs will in turn create jobs and provide their communities with a building material that offers superior insulation and lifespan, maximum fire ratings and low long-term operating costs.

Clay bricks and pavers have a lifespan of more than 200 years. When demolishing existing structures and walls on a construction site, contractors can reclaim clay masonry to use in new building projects or to sell on.

Given their attractive appearance and durability – bricks are good insulators, pest resistant and fireproof – it is not surprising that clay masonry remains a popular construction material.

IC

The weathered look that old bricks provide is almost impossible to reproduce artificially. Thus, recycled bricks are in great demand for certain types of architecture, or to replace pavers or bricks in historic buildings. Damaged bricks can be chipped and used in landscaping or crushed to replace aggregate or sand.

Recycling keeps bulky bricks out of landfill and saves waste handling and transport. Recycled clay bricks provide low-income communities with inexpensive, good quality building materials.

There are limitless ways in which the bricks can be recycled. As a builder or contractor, recycling the bricks isn’t just an economic opportunity; it also reduces the new building’s carbon footprint and earns green building credentials.

HIGH PERFORMANCE PRODUCTS MATERIALS

Zeitz MOCAA heritage protected PHOTO BY GARETH GRIFFITHS IMAGING

Over three years, a complete repurposing of the former V&A grain silo was undertaken to keep its external appearance on par with the works of art to be placed inside and to maintain the original building’s heritage status.

Sika’s high performance products were specified

by Engineers Sutherland and Associates alongside VDMMA Architects (Van Der Merwe Miszewski Architects) in the major refurbishment of the Zeitz Museum.

Sikagard-706W Thixo was applied to the old concrete of the silos as a protective coating and water-repellent impregnation (hydrophobic treatment). This is used for absorbent substrates, such as concrete subjected to heavy stress due to freeze and thaw cycles and de-icing salts, as well as chloride attack in marine environments.

The external façade of the old silos was covered in Sika FerroGard-903 as a corrosion inhibitor. To blend repairs to look like the original silo facade and maintain the integrity of the original structure, Sika Ferrogard-903 was used because of its clear product characteristics.

The structure was initially treated with Sika FerroGard-903 forming a protective monomolecular layer on the reinforcing steel. Used in conjunction with other Sika products in the concrete repair and protection system, Sika FerroGard-903 decreases the corrosion rate so that the service life of aesthetically valuable fair-faced concrete can be increased by up to 15 years.

All new concrete barriers in the main building area were grouted sturdily in place with SikaGrout-212 to provide adjustable consistency, rapid strength development and high final strengths. It expands by gas generation whilst in the plastic state of curing, ensuring a low maintenance system and reducing future costs.

For the sealing of all external joints of the structure’s precast concrete façade, Sikaflex AT-

The treated exterior silo walls

Façade was used as the most effective solution to seal the joints.

SikaTop-Armatec-110 EpoCem, a sprayable cement-based anti-corrosion coating for reinforcing steel, was used for new concrete work against old concrete on the entire external structure where large volume repairs were necessary on newly completed areas .

Sikadur-31 CF Normal was used for doweling on site of the rebar. This solvent-free, moisture tolerant, thixotropic, structural adhesive and repair mortar is based on epoxy resins and special fillers. It is designed for use at temperatures between +10°C and +30°C and provides good adhesion to most construction materials.

The roof of the main museum building was coated in Sikalastic-8800, a two-part, elastic, fast curing polyurethane membrane offering good chemical and abrasion resistance, as well as a waterproofing system.

The entire face of the square building in front of the silos was coated with Sikalastic-152 as a two coat system at a 3mm thickness. The engineer was looking for an earthy, more natural look for the finish and consequently a final coat was applied, including a stipple finish incorporating river sand to achieve this effect.

The staircase and landings (surface area 3000m²) were coated with Sikafloor-263 SL, Sikafloor-264, with Sikafloor 66ZA matt used as a top coat to provide a clear finish.

The main timber floor of the museum was coated with Sikafloor Comfort Tough a self-smoothing elastic polyurethane flooring to approximately 3800m². volume 8 | issue 3 www.tobuild.co.za

Construction industry player shares expertise Photos by AfriSam

As part of its commitment to social and economic upliftment, a South African construction materials leader has put its Centre for Product Excellence (CPE) at the service of small players in the concrete product manufacturing (CPM) sector to empower small business – with great results.

While the ranks of CPMs include a number of large and well-resourced companies, there are still many small and medium-sized enterprises (SMEs) in this industry that need support to become sustainable.

These operations often lack the in-house expertise and experience to fully optimise their production costs, often leaving them uncompetitive.

To help build a sustainable construction industry through empowering SMEs with the necessary knowledge and advice, AfriSam’s CPE offers its technical skills and facilities at no charge to its SME customers. This support is offered across the country. In tough economic times especially, this can often give the customer the necessary edge it needs to survive and thrive.

Advice on best practice

Working with its customer Opehst BCM, a new business near Rustenburg, the CPE team was able

to advise on the best cement and the most efficient process to make bricks, blocks and palisade walling with chrome slag instead of stone aggregate.

Using AfriSam’s High Strength cement (42.5R) to achieve high early strength, Opehst has been able to produce good quality products at low cost. It has entered the market with a competitive offering of products whose quality conforms to South African Bureau of Standards (SABS) requirements.

At Smartcrete in Centurion, the CPE was able to help improve the casting rate so a customer could keep up with growing demand without overly raising its cost base. Through the use of AfriSam’s Rapid Hard cement (52.5R), as well as a superplasticiser admixture and accelerator combination, Smartcrete successfully ramped up the output of its concrete tables, windowsills, wall caps, wall copings, stairs, treads, water channels and spouts.

High performance coatings for harsh environments

Combatting corrosion

By Kansai Plascon

Industries operating in harsh environments must constantly battle corrosion which can be caused by many factors – chemical, heat, abrasion, wear and tear and oxidisation, among others. Left untreated, corrosion causes untold disruption and damage.

Finding a lasting solution to corrosion helps avoid costly unscheduled downtime and improves safety in industrial operations.

A renowned coatings supplier leads the warfare against corrosion with their high-performance products that provide resistance to corrosion in the most aggressive environments across a range of industrial applications.

“Durability and fast application turnaround time are the key benefits.”

Kansai Plascon’s approach to fighting corrosion embraces the wisdom of the age-old maxim “prevention is better than cure”; it is more cost-

effective to prepare a surface correctly and avoid giving corrosion a chance to occur, than to try and rectify corrosion-induced damage after the fact.

Backed by extensive experience in the industrial coatings arena spannning nearly 130 years, Kansai Plascon’s anti-corrosion solutions provide longterm protection against surface deterioration caused by heat, abrasion, fire, chemicals and other harsh conditions. Durability and fast application turnaround time are the key benefits.

Working across multiple sectors, the company’s products are designed for highly-specialised applications. They offer internal and external corrosion protection solutions, including highperformance corrosion protection coatings, chemical and abrasion resistant coatings, fire protection coatings and tank and pipe linings across the food and beverage, mining and metal processing, infrastructure and oil and gas industries. volume 8 | issue 3 www.tobuild.co.za

COPPER MATERIALS

Copper in architecture and interior design Photos by the CDA

Whether you are involved in a new build, adding space to an existing property or simply refreshing a property’s appearance, copper and copper alloys, the most ancient of metals, can give you cutting-edge performance, individuality and colour. So says Levine Warries, Centre Director of the Copper Development Association Africa (CDAA).

The usual grade of copper used for engineering, architectural and plumbing applications is phosphorusdeoxidised copper. It has a minimum copper content of 99.9% with a small addition of phosphorus, which allows this grade of copper to be welded and brazed.

Its thermal conductivity, corrosion, heat and UV light resistance, ease of joining, high ductility, malleability, toughness and 100% recyclability (two-thirds of the copper ever mined is still in use

but still very much in use in many modern-day applications. Formed by mixing various compositions of metals in the molten state, alloys are used to expand properties for specific uses. Alloys of copper give designers and architects more choices in terms of application and colour,’ says Warries.

Brasses are alloys of copper and zinc and have a variety of attractive colours, ranging from red and yellow to gold and silver. With the addition of

Copper applications

today) make copper the standard material for these applications. Electrical grade copper also has a greater than 99.9% copper content and is readily available in many forms.

‘Copper is one of very few metals that has a particular colour, meaning it is not simply silvergrey. Bright copper is reddish-pink, whilst oxidised copper is dark brown. Additionally, when exposed to the elements, copper undergoes a change in colour, known as patination, transitioning from a reddish-pink to a blue-green,’ Warries explains.

Copper alloys

‘No metal is more suited to alloying than copper, a practice dating back to the beginning of civilisation

1% manganese, brass will patinate to a chocolatebrown colour. Nickel silvers may be considered to be special brasses and although they contain no silver content they resemble silver in appearance.

Tin and phosphor bronzes are reddish-brown in colour, whilst aluminium bronzes have an attractive golden colour which will darken slightly over time.

Depending on the copper content of copper-nickels, the colour of these alloys ranges from slightly pinksilver to completely silver in colour, resembling the appearance of stainless steel.

With over 450 approved alloys to choose from, offering a wide range of properties and attributes, it is easy to select an appropriate alloy for the application and fabrication route required. In fact, there will volume 8 | issue 3 www.tobuild.co.za

MATERIALS COPPER usually be several that meet particular design and architectural requirements. Today, copper and copper alloys are available in sheets, meshes and expanded metal which give an air of transparency.

Copper in the home

‘The majority of us take for granted the lighting, heating, communications, running water, domestic appliances and entertainment systems in today’s homes. All of these are reliant on copper components.

In addition, copper and brass are widely used in both utility and decorative items such as cookware, door fittings and furniture. Copper also supports renewable energy and plays an essential role in solar thermal heating and cooling systems, wind turbines and photovoltaic panels that are increasingly incorporated into 21st century homes,’ Warries explains.

Copper plumbing systems ensure the long-lasting trouble-free and safe delivery of water for drinking, washing and heating. They are used in buildings of all types, from hotels and offices, to private houses and apartments. These buildings also remain secure thanks to locks and keys made from copper alloy components that ensure reliability, strength and freedom from corrosion.

Its excellent durability means that a copper component can often outlive the product or application of which it is a part. In buildings, copper cladding, a copper roof or copper guttering and downpipes can last for hundreds of years. Over time, copper used in outdoor applications will weather and oxidise and take on its familiar green patina.

Manufacturers also now have factory methods that can apply oxidised or patinated surfaces straight away.

Science has demonstrated the naturally antimicrobial properties of copper in the fight against potentially life-threatening infections. Bacteria and viruses, including those from the influenza family such as H5N1 (bird flu) and H1N1 (swine flu), are rapidly inactivated on contact with copper. This inherent property has seen the use of antimicrobial copper surfaces dramatically increase in hospitals and food preparation areas. Copper piping also helps limit the spread of Legionnaires’ disease as well as combatting gastro-intestinal infections by reducing the risk of water being contaminated by the Escherichia coli or Listeria bacteria and has applications in hospitals and clinics.

The future – breathable buildings?

With its pores and sweat glands, human skin might be one of world’s best natural air conditioners. Biologist turned architect, Doris Kim Sung, proposed in her TED

118

Hospital applications

talk last October that building skins should be more similar to human skin. Considering that 30 to 40% of all primary energy consumed worldwide goes toward heating and cooling buildings, Sung’s sustainable design concept could be a more passive method for ventilating buildings.

The material she has in mind is a thermobimetal strip — two thin pieces of copper and steel sandwiched together. These two metals expand and contract when heated and cooled. When it is hot the metal bends one way, conversely when it is cold, it bends the other. This means that when direct sunlight hits the bimetal strips, they would bend inwards and close together to shade the building, then when the building gets too hot, the metal could bend in such way that opens up “pores” to release heat.

‘It is unlikely that we will get to the point where we can truly be rid of air conditioning, especially in certain parts of the world, but this application would reduce the amount of air conditioning or heating used just by making buildings more cleverly designed,’ concludes Warries.

MATERIALS INSULATION

Insulation a key component for energy saving Rendering by Saint-Gobain ISOVER

File artists impression of Isover House

Building methodologies have changed radically in the last 50 years and with the growing demand for energy and buildings typically accounting for 40% of all energy consumed in countries, insulation has become a very important consideration when planning a construction project.

Regulations and legislation

It has become such an important factor, that the South African building regulations (SANS10400-XA) prescribe that all new homes must have a certain level of insulation in their roofs to meet specific performance requirements based on certain climatic zones. Rising costs have also forced a need to conserve energy and reduce electricity usage.

Legislation is in the process of being upgraded and it is particularly important that professionals in the industry keep abreast of the new guidelines that will be published soon.

Stringent guidelines, however, also call for the use of innovative products. With ISOVER’s worldclass thermal and acoustic insulation solutions, contractors can support the design of energyefficient construction which provides comfort for users, while protecting the environment.

Saint-Gobain ISOVER manufactures insulation materials from glasswool, mineral wool and expanded polystyrene.

Glasswool is the most effective, environmentally friendly and safest insulation product to use as it is inherently non-combustible and meets the requirements for optimal thermal and acoustic insulation performance. It holds a fire rating of A/A1/1, which means it will not contribute to flame spread and can be used in any class of building

occupancy. Apart from being an exceptional thermal insulator, other benefits of glasswool insulation include: • Acoustic insulation properties • Environmentally-friendly, made from up to 80% recycled glass • Isover glasswool is proudly made in South-Africa • High R-Value per standard thickness, which means products outperform the competitors’ Glasswool insulation products are manufactured for application in multiple areas. Glasswool is most commonly known for insulation in ceilings of residential buildings, but Isover also manufactures products for the following applications: • Cavity wall and dry wall insulation • HVAC and air-conditioning system insulations • Pipe insulation • Over purlin roof insulation in commercial buildings • Suspended ceilings • Industrial roof insulation • Higher temperature insulations • Top-up roof insulation • High performance sound proofing.

MATERIALS STEEL AWARDS

National steel awards impress industry PhotoS by Subiaco

The Southern African Institute of Steel Construction (SAISC) Steel Awards 2018 once again proved that steel is asserting its rightful place in the nation’s built environment. The overall winning project, Time Square Arena, was also the winner in the Tubular Steel as well as Commercial categories.

The Time Square development is located within the bespoke Menlyn Maine precinct, Pretoria and is a Sun International project.

The external box gutter of the Arena was originally planned in concrete, however, looking at the complexity of building scaffolding, supporting of a concrete gutter and fixing re-bar at >15m high levels and weight limitations, it was decided to re-design the concrete gutter to a steel lattice curved box gutter approximately 4m high, with internal 3mm plate formed gutter.

The above were fabricated as complete units from column to column and lifted into position using a 220-ton crane. For the remainder of the Arena roof, the only possible way of spanning 100m was to use a dome-type steer with a compression ring in the centre.

Detailing was done in Tekla and collaboration with the engineers to determine lifting sizes and weights to ensure the steel contractor could erect the steelwork using most economical equipment.

The 3D modelling was important in providing details such as sheeting and cladding, and to model the lifting procedure and method statement.

House Matthews, in Fourways, with a brief by the new owner of the partially constructed site for the architect to ensure that steel remained the dominant element in the design, creating strong features yet also a light quality due to the slabs and walls sitting within the webs of the I-beams. Externally, the use of steel is dominant and aggressive with massive beams and columns. In the interior, steel is forever present, but subtle and discreet where the beams form part of the floor finish, the soffit and the walls.

Old Rissik Street Post Office building, a fascinating project of restoration to a building which is over 100 years old and had been fire-damaged. The designer, Paradign Architects, effectively conceptualised a steel building within the shell of an earlier generation building. Says architect James Wylie: ‘The fire was devastating, but it’s given us a real opportunity to essentially insert a new building into an old building.

We talk about recycling; this is the ultimate recycling of a building and giving it a new life. I actually studied this building when I did my (student) thesis, so the project has been very rewarding on a personal level,’.

The fabricator/steel contractor/erector was MPW Steel Construction.

Light Steel Framing category (LSF)

Gateway West – Mall of Africa – this is heralded as a landmark project that shows much of what can be achieved using LSF, albeit it a low tonnage.

‘The spherically curved and twisted façade walls give expression to the architect’s design through light steel framing, at a much lower cost than would have been the case had reinforced concrete been used,’ read the citation. The steel erector/cladding contractor was Ohlhorst (Pty) Ltd. ‘Despite the enormous difficulties out there, our industry continues to produce outstanding work, demonstrating its capability and expertise. This year we had 74 entries, reflecting steel as the material of choice. Steel structures of all types are on display due to the all-round efficiency and sustainability of the material - it’s no wonder steel is being used more and more!’

The compression ring was built completely as a bolted assembly, standing over 6m tall in the workshop. After pre-assembly in the workshop, it was dismantled and sent to site in loose elements.

It had to be installed central to the Arena and at the correct level to ensure roof truss fit. To achieve this, a central scaffold tower was designed by Form Scaffolding in conjunction with WSP and the main contractor.

Main roof trusses were installed in segments supported by temporary designed columns to limit truss lifting weights and limit crane loadings on the slab.

A remarkable achievement of this Arena installation is that it took only two-and-a-half months to install all the roofing and infill steelwork after the compression ring was installed and levelled on the central scaffold support tower.

Over decades, ZINCALUME® steel has become a household name within the building industry. When specifying premium high performance metallic coated roofing and cladding materials, this original and trusted brand remains the roofing material of choice for specifiers, says Arno Hanekom, the BlueScope Steel Regional Manager for Africa and the Indian Ocean Islands.

124

The product’s 55% Al-Zn technology is licensed internationally by BIEC International Inc, a BlueScope subsidiary. In the mid 2000’s, the acrylic surface resin applied to coils of the product at the factory was upgraded, yielding significant advances in performance and formability.

The choice of roofing material influences the amount of solar energy that enters a building, affecting climate control and building comfort. To mitigate against heat, ZINCALUME® steel has an attractive, shiny appearance designed to limit solar absorption. All roofing products are subject to weathering, however, BlueScope’s product will stay brighter for much longer than alternatives, providing approximately twice the thermal performance of other commonly used materials such as weathered galvanised steel and fibre cement and asbestos.

‘ZINCALUME® steel delivers strong thermal performance throughout its life. It’s also very easy to form and work with,’ says Hanekom. ‘It stays brighter for longer. Due to its lightweight nature, it is the architect’s dream material for curves and

shapes and has been formed into a variety of curved surfaces. A good example of this is the roof over the departures terminal at Cape Town International Airport which is shaped like an aircraft wing.

Above: ZINCALUME® has been used extensively throughout South Africa. Clotan Steel expertly formed ZINCALUME into its Craft Lock profile in use at the Secunda Mall, as specified by architectural firm, LP Architects. The double-story mall was completed late in 2013.

The corrosion-resisting benefits of the product are considerable and a special AZ 200 (both sides coated with 200g/m2 of Al-Zn coating) version is available for use within the 5km distance of the sea or in areas where there is a strong industrial fallout.

The product’s lifetime in service is reported as being four times longer than conventional galvanised products.

‘Hence a special corporate warranty of performance can apply when product is fitted in an approved way,’ adds Hanekom.

‘If the good name of your practice is on the line, why risk your reputation by using generic Al/Zn coated steel when you can enjoy peace of mind by using genuine ZINCALUME® steel?’ asks Hanekom.

Steel industry leader: Colin Hautz Photo by ArcelorMittal South Africa

Colin Hautz is the Chief Marketing Officer at ArcelorMittal South Africa.

To Build asked him about his views on the industry and his executive job at the steel major.

How long have you worked for the company and what did you do prior to joining them?

I joined ArcelorMittal South Africa just over a year ago, after 14 years in corporate roles in the ArcelorMittal Group in Continuous Improvement, Group Marketing and Corporate Strategy. Prior to ArcelorMittal, I worked for Accenture and General Electric Plastics.

What are the challenges, in your view, that the building sector faces with regard to the use of steel as a building material?

To my mind the challenges fall into three broad categories; that steel is under-recognised for its present importance as a building material, is underappreciated in terms of the benefits that it can offer the construction industry and is held back by the innate conservatism of the building sector.

Starting with the conservatism of the building sector, this is fundamentally a desirable trait; if buildings or infrastructure fail, the consequences are often dire. The tragic example of the collapse of the Motardi Bridge in Italy is fresh in all our minds. It is good that the industry is risk-averse, but that should not be a reason not to spread new, proven building methods, whether proven inside South Africa or elsewhere in the world. Steel-based building concepts are pushing the boundaries of imagination and meeting the increasing requirements of green credentials and the circular economy.

Steel’s structural role in construction is often over-looked and under-recognised because it has until now been hidden within a mass of concrete.

However, that does not diminish the reality that, globally, construction is the single largest market for steel and more than half of all the steel

126

produced annually goes into construction. The speed of urbanisation globally is clearly visible because of steel enabling faster, higher and lighter construction.

The fact that steel is mostly used in combination with concrete means that performance expectations are generally set by that combination and the performance benefits that steel itself offers go under-appreciated.

STEEL MATERIALS

For example, steel provides design freedom in terms of shape, space and finish to create beautiful and unique structures that meet the latest environmental performance standards. Or the speed of construction can be increased with fewer materials delivered to a job site, reducing the impact on the neighbourhood. But most crucially, there are the economic benefits. The adept use of steel solutions can maximise the available floorspace within a building by removing columns and increase the flexibility of how that space can be used. The thickness of floors can be reduced to create more usable volume or, if the building is tall enough, another floor. Apart from increasing the rent-generating capacity of a building, steel-based solutions can reduce the total cost of ownership of a new building by up to 15%.

What is important about being a local player with a production capability?

South Africa is an amazing country with an abundance of natural resources, including the raw materials to make steel. By transforming South

“Not only is it important for South Africa to utilise its own resources and create value within the country, but many innovative steel-based solutions can be implemented faster and more cost-effectively than traditional construction methods.”

Do you see steel as having a crucial role in building the nation?

Of course; not only is it important for South Africa to use its own resources and create value within the country, but many innovative steel-based solutions can be implemented faster and more costeffectively than traditional construction methods.

Not only can more be built with available funding, but those projects can be completed and deliver impact on the economy sooner.

Where does ArcelorMittal South Africa source its technology?

As part of the larger ArcelorMittal Group, ArcelorMittal South Africa is able to draw on the Global R&D and technology departments, either to support ArcelorMittal South Africa in its own developments or to transfer solutions which have been developed elsewhere in the Group.

Any there any new products on the horizon?

We have recently introduced some new products for the roofing and cladding sector, including a matte and a wrinkle finish for colour-coated product, namely Chromadek®.

Also, aligning with international best practice, at the start of this year ArcelorMittal South Africa converted its full range of reinforcing bar to conform to the BS4449:2005 Grade 500 specification. This Grade 500 rebar surpasses the SANS standards and can be used in any construction where 450MPa rebar has been specified. volume 8 | issue 3 www.tobuild.co.za

African iron ore into steel within the country we keep the value-addition within the local economy, supporting both a stronger manufacturing sector and investment in the nation’s infrastructure.

On top of that, construction materials are heavy so it is predominantly a local industry. Not only is there the cost of transporting materials, but the environmental impact of transportation is becoming more important, especially given the increasing regulations around carbon emissions.

Technical note: About TCT in coated steel

By Dennis White, South African Metal Cladding and Roofing Association (SAMCRA)

There is a certain mystique surrounding the thickness of coated metal cladding. To begin with all coated coil producer mills refer to the thickness of their products as being ‘nominal’ with a permissible variation (tolerance). Tolerances are normally quoted as plus and minus; however, some mills will produce coil with only a plus or minus tolerance. Locally the tolerance for material up to and including 0.50mm is ±0.02mm, between 0.51-0.58mm ±0.03mm and 0.59-0.80mm ±0.05mm.

Another variant is whether the thickness is total coated thickness, excluding paint (TCT) or base metal thickness, i.e. the thickness of the steel core (BMT). Currently the thickness of locally produced coil is TCT. Following discussion during the writing of SANS 10237 (the new cladding code to replace the former SABS 0237) and the revised version of SANS 10400-L, it was agreed to change to BMT when these codes are published soon. During the transition period coil will be branded with both TCT & BMT thicknesses. Future span tables for cladding profiles will be based on BMT. For clarification on branding refer to the article entitled “Are you getting what you specified” on our website.

About the various types of protective coatings, two systems of measurement are used: 1. Mass per unit area for metallic coatings 2. Dry Film Thickness (DFT) for painted coatings.

Metallic coatings have an alpha-numeric designation, the alpha defines the type of coating for example Z for galvanized and AZ for 55% aluminium zinc alloy. The numeric portion defines the mass in g/m² for example a Z275 coating indicates a combined total (both surfaces) of 275g of zinc per 1m² of material. This translates into a thickness of approximately 19m per surface.

Painted coatings are measured in terms of the DFT of the total coating system (i.e. primer plus top coat) measured in m.

The transmission line industry in South Africa Photo by Gareth Griffiths Imaging

A state of the industry paper written by industry expert, Gary Whalley1, was sent to the editor by the Power Line Association of South Africa (POLASA) sketches the enormous pressure that this vital segment of steel construction is facing. POLASA is a key member of the Southern African Institute of Steel Construction. The paper asks whether the industry is “a sinking ship?” We publish highlights from the full paper, which is extensive.

The South African local transmission line industry finds itself in extremely choppy waters. No new high voltage transmission line projects have been launched into the market since late 2016.

Eskom, as the sole provider of high voltage transmission line infrastructure, faces a severe cash crisis which calls into question its ability, or desire, to launch necessary new capex projects to market when it is struggling to address its operating cash needs. While there is a need for additional infrastructure to evacuate power from its new power stations and reinforce the network’s capability to supply remote demand areas, its regulated grid code requires an N-1 grid capability not yet addressed.

The local South African transmission industry, having largely delivered on Eskom’s projects, finds itself in distress, experiencing significant job and capacity losses through business down-scaling, distress or business exits from the sector.

Is the local industry doomed to failure or will a concerted South Africa-first approach between stakeholders create a sustainable industry able to under-pin South Africa’s grid requirements as a first priority?

The paper is an attempt by POLASA to table the significant issues that must be addressed and resolved by stakeholders to avoid further job losses, loss of manufacturing capability and the destruction of a local industry which would result in South Africa becoming a price-taker for critical and necessary transmission line infrastructure.

Despite its niche nature, with peculiar skills and unique operating environment, this industry plays a vital and critical role in enabling Eskom to meet its mandate of delivering critical transmission infrastructure, to integrate electricity generation with its broader electricity distribution, to underpin the growth and development of the nation.

Framework

In a consistent manner Eskom has, from 2006 onwards, exhorted the local transmission line industry to invest in and increase its capacity to deliver on its requirement to build 1 000km of transmission lines per year. In keeping with Eskom’s social mandate, local industry was encouraged to incubate smaller contractors to further enhance and develop capacity, as well as ensure that safety of the industry remained a non-negotiable imperative.

POLASA’s mission reflects Eskom’s position, seeking to establish and support a “viable and sustainable power line industry”. In a concerted and earnest response, the local industry increased capacity over the period from 2006 to 2018 through: • capital investment in specialist equipment and new technologies • extensive recruitment and training of personnel • incubation of smaller contractors to increase capacity • concentrating on localisation of manufacturing, skills and expenditure for the benefit of the areas of operation and the country • transformation of local companies to address the imperative of BBBEE, and • the establishment of POLASA in 2013.

The demand for transmission line infrastructure peaked in a bubble of work released by Eskom to the market in 2011 when 1 700km of lines were put out on enquiry. A concerted effort by local industry saw it win and execute 40% of these projects or about 680km through 2011 and 2012. The balance of contracts were awarded to five multinational companies who struggled to deliver the 1 000km through 2011, 2012 and 2013.

By 2013, the local industry faced a “burning platform”, with some 5 000 jobs jeopardised and a complete interruption of work for 12 months due to a lack of projects being put into the market by Eskom. POLASA published its “Burning Platform” industry paper as a platform to engage stakeholders on the crisis in the industry. Inherent risks in the roll-out of transmission infrastructure were then identified. Eventually, four of the five multinationals involved in the industry left South Africa, some

vowing not to return due to inherently difficult operating environment.

“Sinking Ship?” or “Sinking Ship!”

Despite extensive engagements with stakeholders from 2013, another peak in demand arose in 2015 when Eskom launched some 2 200km of transmission line enquiries to market.

Despite the intensely difficult operating conditions, the local industry has risen to Eskom’s needs. To date, of the 1 300km of this tranche of work which is completed, 92% or about 1 200km has been built by local companies. Of Eskom’s Shareholder Compact kilometres, local industry delivered 95% in 2016/2017 and 100% in 2017/2018. The local industry certainly has not been without fault in its delivery of these kilometres, struggling to deliver work contractually on time and within contracted cost.

The majority of the 900km left to build are in the hands of multinational companies that continue to struggle to deliver transmission line infrastructure in South Africa. In certain instances, Eskom has been obliged to remove contracted work from these companies due to non-performance arising from parent companies being in business rescue in their home countries, either at or around the time of contract award from Eskom.

In the interim, the local industry is confronted by the crisis of no new work coming to market for over 18 months. Unless serious interventions are made, over 6 000 jobs will be lost at a time when the country can ill-afford additional unemployment.

Local companies, large contractors, smaller incubator contractors or secondary suppliers are in financial distress and are downsizing or exiting the industry. The inherent risks identified in 2013 remain unchanged and have in fact been exacerbated by the socio-political environment in the country.

Without intervention it is highly likely that the local capacity to deliver on new transmission infrastructure will be destroyed.

Custom stainless steel balustrades at Discovery in Sandton

Saving lives one balustrade at a time Photos by Steel Studio

A leading manufacturer informs readers what they are doing to change the balustrade industry to ensure the safety of the consumer.

It’s no secret that for many years the South African National Standards have been clear about balustrade safety regulations. Not only that, but in 2011 changes were made to the SANS in regard to balustrades that impacted the way balustrade contractors were expected to manufacture and install their products to ensure the safety of the consumer.

In today’s uncertain economy, the consumer is looking at where they can save. Consequently, by looking at the bottom line only and not taking safety and quality into account, consumers become easy targets for unscrupulous contractors. What’s more, the consumer doesn’t expect a contractor to install an inferior quality product and risk the consumer’s safety just to make a quick buck.

As a result of this unprincipled behaviour, and far too many accidents that have caused injuries and even death, Steel Studio has launched their “saving lives one balustrade at a time” campaign.

This campaign includes a series of educational and informational emails that equip the consumer with knowledge and guidelines on what to ask for when buying a balustrade system.

Industry accreditation In addition to the campaign, Steel Studio has also joined industry associations like AAAMSA and SASSDA to act in getting their members to become accredited manufacturers and installers and as a result, produce systems that are safe and compliant with SANS. What Steel Studio is doing to ensure the safety and quality of their products Conscious designing and testing of balustrades Every balustrade system is designed and tested in consultation with a professional structural engineer. On completion of a balustrade project, the customer receives a Form 3 ‘Declaration by a competent person appointed to design a component or an element of a system, from the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977)’.

Without this Form 3, you are not guaranteed a safe balustrade installation.

Steel Studio testing performance of chemical anchors fixed into concrete

Testing of chemical anchors Chemical anchors are used to fix balustrades to concrete or other surfaces. All undergo comprehensive tests in consultation with the anchor manufacturers and professional structural engineers to ensure their suitability for the application intended.

There is no price to your safety. By ensuring that your balustrade contractor complies with SANS, you are guaranteed a system that will protect those that use the building. The material guarantees alone will save you future maintenance or replacement costs on inferior installations.

To join thousands of other homeowners and building professionals with a common interest in safety, the company offers a subscription to a newsletter to receive updates on its “Saving lives one balustrade at a time” campaign.

Glass with the SABS logo

Certified balustrade materials All raw materials used for balustrade manufacturing is locally sourced. Stainless steel is sourced locally and the correct grade of stainless steel for the application is guaranteed by means of certification from the local mills. Toughened safety glass is sourced locally and is SABS approved.

Superstellar

Stellar Stuff Photos by OKHA

Stellar comes from the Latin for “star” and is epitomised in a leading designer/manufacture’s range of Stellar and Super Stellar candleholders by designer Adam Court , which draw on both cosmic and cultural references.

Why Stellar? Available through OKHA with offices in London and Gardens in Cape Town, the manufacturers claim that stars are the result of a heated compression of inter relational forces; the force of gravity compresses atoms in interstellar gas until the fusion reaction begins and a new form is born. The same description can be applied to many elements, including human nature; where the often fascinating and unpredictable results of bringing opposing elements and forces together give life to a new entity, form or perspective.

For designer, Court, the Stellar and Super Stellar candleholders are imbibed with “the emotional evocation of starlight, movement, combustion and constellation”. He has also used a name which will remind people of the tragic and sensual women of

140

Tennessee William’s “A streetcar named Desire” and Dicken’s “Great Expectations” applying “the dynamics of opposing forces; two intersecting planes colliding to create new perspectives and alternative dimensions”.

The blue and green Stellar have undergone a rigorous process of oxidization and patination to attain their depth of colour. Both are made of mild steel whilst the golden Super Stellar are of solid polished brass.

‘All weigh more than they visually imply; these are not trinkets to fulfil a passing fancy like so many things in the age of consumerism, but rather they achieve a level of design integrity and value placing them in the very small and desirable category of objet d’art,’ explains Court.

SERVICES PLUMBING & RETICULATION

Solving waste water treatment problems By supplying over 3 000 Quick4 Infiltrator Chambers for the new Charlestown Housing Project in Newcastle, KwaZulu-Natal, a plumbing and reticulation specialist was able to completely eliminate the need for a conventional French drain soakaway system.

Manufactured from recycled plastic waste, Kaytech’s eco-friendly Infiltrator Chambers deliver a high level of performance on every front – from ease of transportation, handling and installation, to system reliability. Infiltrator Chamber Systems promote effluent infiltration into the soil with 100% efficiency while requiring as little as 50% less space compared to French drain systems.

The Charlestown housing project was designed to comprise 1 200 units when complete, with an on-site sewage treatment plant planned for a later stage. As a temporary measure for the 500-unit phase one already under construction, MNA (Makhaotse, Narasimulu & Associates) Consulting required a French drain system to be installed downstream of an adequately sized septic tank.

The problem, however, was the prohibitive costs of transporting tons of stone for the conventional stone and pipe French drain system. With the feasibility of the whole project reliant on an effective alternative being found, the engineer approached Kaytech for a possible solution.

After being informed by Kaytech representative, Yugeshnee Naidoo, that the Quick4 Infiltrator Chamber System was not only a direct replacement for old fashioned French drain soakaways, but is also a significantly more economical alternative, the engineer readily conducted a series of percolation tests and gathered geotechnical information on the area allocated for the French drain system. Using this data in conjunction with the allocated wastage

142

litres per unit, Kaytech and the engineer designed a complete Infiltrator Chamber System. To allow for reductions in behaviour of the in situ material, the design incorporated factors as per the specified design codes.

In early February 2018, contractor, Pilcon Projects, commenced excavations and within four months had installed 3 079 Infiltrator Chambers, effectively covering a distance of 3 757m.

Installation was very simple with the Infiltrator Chambers clipped together in rows in 0.9m-wide trenches. A 2.5m centre-to-centre spacing between each row simplified excavations and placement of chambers in the multiple rows. To ensure efficiency of the drain, each row of chambers was closed with an end cap, maintaining the void and preventing contamination from surrounding material. A total of 112 end caps were installed.

With a proven track record exceeding 30 years, tried and tested Infiltrator Chambers provide numerous benefits, including quick and easy installation, flexibility as well as chemical resistance and UV stability.

Compared to conventional stone and pipe soakaways, Infiltrator Chambers require no heavy installation equipment, no stone, less labour and occupy a smaller footprint, minimising site disruption as well as reducing on-site clean-up time. The arch design of each chamber can support axle loads up to 70kN. Due to this far more economical and construction-friendly solution designed by Kaytech and the consultant, costs for the Newcastle Municipality were significantly reduced.

GREEN BUILDING CASE STUDY

Visualisation of 570 Broome, New York, USA

Reaching higher ground Renderings by builtd

As urban areas become more crowded and populations increase, so too do greenhouse gas emissions. These directly impact on public health and contribute to negative phenomena, including global warming and acid rain.

According to recent findings from the United States Environmental Protection Agency, ‘Since 1990, gross US greenhouse gas emissions have increased by about 2%’ and, whilst figures have been slowly decreasing in the last few years, emission levels remain unacceptably high. Of the total figure (6,511 million metric tons of CO2 equivalent), transport alone makes up 28% of the total output . Much of this is concentrated in densely populated towns and cities.

The gradual rise in popularity of Green Buildings over the last decade reflects an ever-increasing awareness amongst business, industry and the consumer of ecological issues and concerns, particularly pollution levels and the effects on national wellbeing.

As such, architects, designers and contractors are actively exploring more environmentally-friendly solutions for future construction and retrofit projects.

On the face of it

One area in which extensive research has been carried out is on structural facades and cladding, the

144

building’s first point of contact for elements and manmade emissions.

It was against this backdrop that Neolith® was approached by architectural firm builtd which was looking to build a 25-storey commercial condo tower at 570 Broome (Soho, Manhattan), in close proximity to New York’s highly-congested Holland Tunnel.

The client specifically wanted to construct a durable building which could withstand both physical damage and natural and man-made atmospheric deterioration, such as UV-rays and car exhaust fumes. The client also wanted to specify a low-maintenance surface which would not stain over time. These were all performance properties inherent in Neolith’s composition.

Façade

Neolith had already been specified as the material of choice for the 570 Broome facade when its partnership with photocatalytic treatment manufacturer solutions, PURETi, was announced in spring 2017.

volume 8 | issue 3 www.tobuild.co.za

143-149_Green Building.indd 144

2018/10/21 9:04 PM

CASE STUDY GREEN BUILDING

Essentially, the application of PURETi’s waterbased, photocatalytic preventative maintenance solution on Neolith slabs enhances its surface, transforming them into self-cleaning air purifiers.

Furthermore, this ingenious technology has the ability to reduce air pollution by destroying nitrous oxides (NOx) and volatile organic compounds (VOCs) that come into contact with the treated stone, only using the energy from natural sunlight.

Taking the initiative, Neolith’s US team suggested that this innovation would be perfectly suited for the skyscraper, given both the initial design brief and its location in a high-congestion area.

‘The initial selection of the Neolith panels was for their lightness and aesthetic qualities, but once we found out it came with this element, we were like, of course! It’s a huge plus that PURETi-treated slabs also limits the amount of maintenance required. Instead of using chemicals and power-washing the façade, the material is hydrophilic so it cleans itself,’ explains builtd’s principal architect, Tahir Demircioglu.

On a grand scale

A total of 2 000m2 of PURETi treated Neolith Jura Limestone (a custom colour produced especially for the project) is being used for the façade on all sides and for framing the three-storey high expanses of glazing on the front of the building. These require sensitive and careful installation using lightweight aluminium frames which provide both strength and flexibility.

Because the project is being constructed in a heavily built-up area with unpredictable weather conditions, a number of regulations need to be met, particularly in regard to New York City’s stringent fire and combustibility code.

Sheet resistance tests have also been carried out to guarantee the durability of the PURETi application on Neolith surfaces.

Construction of 570 Broome is set to complete at the end of 2018.

The game changer

Commenting on the significance of the project, Neolith’s Mar Esteve Cortes explains: ‘This project marks an important milestone in the partnership between Neolith and PURETi. 570 Broome is the first project in which the treated slabs have been specified on such a large scale. It’s truly awe-inspiring.’

‘There can be no doubt that this is a game changer in the way that we approach urban planning and construction. We cannot wait to see how it makes a positive impact on the lives of both 570 Broome’s residents and New York City citizens in general. Hopefully, this example will encourage other architects and specifiers globally to consider greener façade options for future high-rise projects,’ she adds.

OPINION GREEN BUILDING

Shifting the date Retrofitting existing buildings, industries and datacentres and upgrading electricity production with renewables alone would move the Earth Overshoot Day back by 21 days, suggests a leading technology-focused group.

Earth Overshoot Day (EOD) marks the date in the year by when humanity will have consumed more from the planet, including food, fibres, timber and absorption capacity for carbon dioxide from fossil fuel burning than the planet’s ecosystems can renew in the entire year.

The company, a leader in digital transformation of energy management and automation, believes that adoption of energy-efficient and renewable technologies such as its IoT -enabled EcoStruxure platform, could move the date back by 21 days through retrofitting of existing building, industry and datacentre infrastructure and upgrading electricity production alone.

To demonstrate how this can be done and to promote new approaches to sustainable business thinking, the company has partnered with Global Footprint Network (GFN) to demonstrate how existing technologies can help to move the date of EOD. GFN is the international research organisation that is changing how the world manages its natural resources and responds to climate change.

CO2 savings through energy efficiency and renewable electricity

Believing EOD is reversible, the company has calculated that if 100% of existing building, industry and datacentre infrastructure was equipped with active energy efficiency technologies that are readily available and the electric grid was upgraded with renewable capacities, the world could move the date back by at least 21 days.

‘Operating on a planet with finite resources requires creativity and innovation,’ says Xavier Houot, Schneider Electric’s SVP Global Environment. ‘We team-up with our customers and partners to unlock the potential to retrofit existing infrastructure, adopting circular business

models, and we measure how much this helps save resources and CO2.’

Schneider’s EcoStruxure is an enabler

Central to the company’s strategy is EcoStruxure, an eco-designed, IoT-enabled, plug-and-play, open and interoperable architecture and platform, aimed at all power-consuming sectors, including homes, buildings, data centres, infrastructure and industries.

EcoStruxure Building is just one example of the platform in action. The technology can deliver up to 50% energy efficiency while reducing energy costs by 30%. It works on three key levels: Connected products: In buildings, connected 1. sensors and meters improve the efficiency of networked lighting, heating and air conditioning, increase security and optimise the use of space in the building; 2.

Edge control: This layer gives users the capability to manage the data from IoT-connected products on-site, with day-to-day optimisation of energy consumption through remote access and advanced automation; Apps, analytics and services: Visualised reporting 3. on energy consumption through interactive dashboards, detection and diagnosis of faults, performance analysis and asset monitoring enable the detection of additional energy-efficiency opportunities and the transition from curative to predictive maintenance.

‘Their business case is aligned with moving humanity out of ecological overshoot’, says Global Footprint Network CEO, Mathis Wackernagel.

‘Leading companies are rising to the challenge of managing natural resources differently, measuring them accurately and developing more efficient products and processes, reducing overall use.’ www.overshootday.org volume 8 | issue 3 www.tobuild.co.za

GREEN BUILDING RECYCLING

Collective accountability needed Photos by Interwaste, WORDS By Kate Stubbs, Director Business Development and Marketing at Interwaste

Initiatives such as Clean-up and Recycle SA Week are a great measure to raise awareness about the waste-to-landfill versus recycling conundrum South Africa faces. However, the message needs to be far clearer; that Government, corporate South Africa and individual citizens all have a role to play and a strong focus should be placed on driving collective accountability if we are to reduce landfilling and increase recycling of waste in the country.

The status quo

Looking at the current state of waste management in the country, it is clear that landfilling remains the most common method of solid waste disposal in which South Africa is lagging far behind other developed and developing economies in terms of recycling. In fact, a report on eNCA television news indicates that the country is only recycling 10% of the 108 million tons of waste generated annually.

It is also estimated that last year R17-billion of waste was disposed of to landfill that could have been rerouted back into the economy by means of recycling, repurposing and reusing.

These statistics are startling; but what is perhaps more shocking is the knowledge that without immediate interventions to change how we manage recyclable versus disposable waste, the country will be facing a massive waste management crisis. For example, without drastic change to divert waste from landfill, it is estimated

148

Johannesburg will run out of landfill space in less than 10-years.

If we are to change the current status quo around recycling we need to understand that such an initiative will require buy-in, involvement, collaboration and participation at all levels of society. The willingness to change behaviours is often the hardest thing to secure, but it can be done.

While a complete culture change towards recycling and waste management won’t be achieved overnight, if we look at the water crisis, particularly in the Western Cape, there are two key lessons: 1. Behaviour change can certainly be achieved when faced with a looming crisis, but perhaps more importantly 2. How the environmental impacts can be slowed and reversed if we proactively change behaviour – and before the situation becomes critical.

RECYCLING GREEN BUILDING

Legislation has a leading role to play

Over the past several years, new legislation has been developed to support more environmentallyfriendly and sustainable waste management processes; to improve the disposal of waste to landfill and, more importantly, to encourage the waste industry to seek alternative solutions.

One of the most significant developments has been the prohibition of certain waste streams from landfill disposal as from 2013, with additional waste streams falling into this prohibition on an annual basis. It is imperative that local industry stakeholders are aware of this legislation and take the necessary steps to comply. Critically, these prohibitions represent an opportunity to seek alternative and more sustainable waste management solutions and create a more efficient waste economy in South Africa.

The National Government has also put policies in place to support the implementation of the new legislation and overall to divert certain waste from ending up at landfill sites. An example of this is the National Waste Management Strategy launched by the national Department of Environmental Affairs to promote waste minimisation, re-use, recycling and recovery of waste, among other things. Government is therefore trying to establish a more uniform way to ensure all public and private sector entities and citizens recycle all their reusable products as far as possible and contribute to national recycling initiatives and programmes.

Another programme that will lend great support to the National Waste Management Strategy is the initiative launched by the City of Johannesburg in July this year making it legally compulsory to separate at source. This is a prime example of the types of policies, structures and systems that cities and local municipalities across the country are going to need to begin instituting and implementing in support of and to adhere to national legislation.

And, although the logistics of the City of Johannesburg’s programme are still being finalised and will be rolled out in a staged approach, the ideal is that every household and public and private sector entity will take its fair share of accountability. This means ensuring that they separate their waste at their residence or office building, using colour-coded plastic bags for different materials which will make it easier for the waste management company responsible for the collections to ensure that all the waste is appropriately recycled or disposed of.

SA retail brands make their pledges

Other initiatives that shouldn’t go unnoticed are the efforts and commitments already being made by private companies to adjust some of their business practices, including leading retail chains.

Proactive waste management offers employment opportunities

While recycling offers many environmental benefits, its ability to also create jobs cannot be emphasised enough. In fact, the waste picker sector is on the increase and plays a key role in South Africa’s recycling strategy. Waste pickers are reported to make between R290 and R770 from the waste they collect, demonstrating the potential of waste in creating an income stream for individuals.

As recycling becomes more of a national priority, it presents more opportunities for waste pickers to work as one-man-bands to support their families, or potentially to organise themselves into small businesses. With this in mind, if given the correct resources, the waste pickers can also become more empowered and hopefully employ other members of the community, further contributing to combatting unemployment.

Waste management can no longer be approached with a linear view and we need to be thinking ahead, adopting an all-encompassing view with innovative and best practice for recycling and waste reform. Succeeding in this will take significant buy-in from Government, corporate South Africa and individual citizens as every sphere of society has a shared interest and therefore an important role to play in adopting positive behaviours to reduce their waste, practice separating and recycling at source and contributing to the overall sustainable waste management aims of the country.

Students shine at SAISC Awards Three university students, all Cape Town based, received honours at the glittering SA Institute of Steel Construction SA banquet held in the Mother City. Simultaneous banquets were held in both other major centres.

The Cape Town version of the Steel Awards was sponsored by Aveng. To Build reviews the projects of two of the award winners.

Stefan Löffel - Minimising impact of fires in informal settlements

Informal settlements are residential areas which form an iconic part of the South African landscape.

They can be defined as an assortment of informal dwellings which have been illegally constructed on land that has not been formally surveyed or proclaimed for residential purposes by the appropriate authorities.

Residents within informal settlements often live in densely populated dwellings which are frequently constructed from combustible materials. Many of the residents within these communities suffer from abject poverty and cannot afford safe energy

sources required for daily activities such as cooking, cleaning and heating and this increases the risk of a fire breaking out within their dwelling.

From 2003 to 2015 there has been an approximate increase of 65% in the number of fires reported in informal settlements throughout South Africa.

When considering the high fire-related burn mortality rate, increasing number of people living in informal dwellings and the government’s struggle to provide formal housing at the rate at which it is required, as well as the practicality of current interventions, it becomes evident that there is a massive need to address the issue of improving the fire safety within informal settlements to limit the effect within the community in the event of a fire.

Currently, there is limited research being conducted in terms of containing and suppressing

informal settlement fires and how to minimise the impact of such fires within communities. Annually, a substantial amount of money is allocated towards fighting such fires in informal settlements. However, with a lack of understanding of how fire spreads throughout these communities, sometimes the money is not being spent as effectively as it ought to be. There is no formal research which quantifies the performance and practicality of suppression products and construction systems in informal settlement fires.

To this end, the Fire Engineering Research Unit at Stellenbosch University (FireSUN) is conducting research to quantify the performance and practicality of various existing suppression products and construction systems in the event of a fully developed informal settlement fire. The goal will be achieved by means of experimental testing and will hopefully assist in improving the fire safety in informal settlements throughout South Africa.

Adam Oodally - The ‘Serpent ‘inspired

by Kirstenbosch’s Boomslang

According to Oodally: ‘The design of our pedestrian bridge – The Serpent – was inspired by Kirstenbosch’s Tree Canopy walkway. Our group of designers aimed

for a light and transparent design that adequately fit into the lush green environment surrounding the University of Cape Town.’

Called “the Serpent”, the design constitutes steel columns in the form of trees spread along the span of the deck. Besides the aesthetics, this design eliminates structural challenges such as torsion or punching shear. The deck is made of a thin concrete slab wide enough to allow for cyclists and pedestrians. Large spans between the steel columns were achieved by using a vertical curvature along the bridge. The name of the bridge roots itself from the overall shape that it takes whilst meandering through the trees on the site. The walkway merges with the existing pedestrian and cyclist routes but also allows for the use of wheelchairs.

‘The Serpent is a masterpiece that combines functionality, aesthetics and simplicity,’ Oodally adds.

And the judges seemed to agree.
