editorial

Imports do more harm than good A local coated steel manufacturer argues the benefits of local sourcing. As the traditional saying goes, “goedkoop is duur koop”, meaning cheap is expensive. This especially applies in the context of cheap imports. Cheap now usually means expensive later. The recent flood of cheap alternatives for galvanised coated steel and aluminium-zinc coated steel is a case in point. More often than not, savings in the short term are cancelled out by increased remediation costs in the long term and, worse still, the crippling of the local steel market and the industries it supports.

Can we afford to ignore the risk? Many major south African client companies are known to have introduced a policy known as best country sourcing. While this doesn’t necessarily mean that they define best as cheapest, inevitably price and availability are the strongest factors. Often this means that imports from China come out tops. Cut-price sheeted roofing materials are typically used in the lower income sectors and low-cost housing projects. Experience has shown that these materials are often of inferior quality, leaving them vulnerable to corrosion or collapse. With severe weather conditions increasingly lashing the country, we ignore the risks

of poor-quality sheet metal at our peril. Not only are lives at stake, but so is public money when it comes to disaster relief – along with the reputation of the entire sheeted roofing industry.

Importing: the flip side of the cut price coin In the south African market, aluminium-zinc and galvanised steel are the most commonly used coated steel products. It would be naïve to say that companies who import cheap coated steel products haven’t taken into account the added cost of import duties and shipping. Despite the duties and costs involved, many companies still claim it is cheaper to import product. However, what these importers fail to consider – from an economic position as much as from a moral consideration – is the long-term impact on the local steel manufacturing industry. The multiplier study undertaken by the south African Institute of steel Construction (sAIsC) showed that every tonne of structural steelwork that is fabricated here creates jobs and economic activity – both in the industry and among the associated industries that supply products and services to them. Taking it a step further, every employee in these

editorial industries spends it on housing, food, and a variety of other things – all providing a livelihood to other South Africans.

Why is local lekker? Buying locally fabricated steel is good for the local economy. Given the energy and expense that both government and the private sector put into creating new jobs and providing incentives for local productivity improvements, any practice that puts these gains at risk – especially for dubious short-term gains – is counter-productive. As Kobus de Beer, industry development executive at the SAISC, has aptly said: “It is time for us to appreciate that we cannot afford to lose our industries, especially those that are not high-tech but provide employment for typical South Africans. It is time for us to appreciate that the world is moving in the direction of increased protectionism, as free trade and globalism have not proved to be all they were cracked up to be, especially from the vantage point of the majority of the population.” (Steel Construction Journal, Vol. 36, No. 6) South African consumers are protected by the Consumer Protection Act – but only for locally sourced products. Buy your steel from abroad and the terms of this Act do not apply, meaning no protection.

Sourcing a quality product Quality products must conform to all the necessary SANS performance requirements. This knowledge should give the client confidence that a quality product is being used – and a legitimate claim if it fails. Considering the hidden costs of importing from the East and the weaker rand, South Africa is actually competitive from a price perspective. Since 2006, the local steel-construction industry has almost doubled its production capacity to meet the growing requirements of large-scale infrastructural projects such as the World Cup stadia, the Gautrain, and road upgrades such as the Gauteng Freeway Improvement Project. With new production facilities, equipment and materials management systems, South Africa is “one of the best-equipped and most productive steel industries in the world,” according to Hennie de Clercq, executive director of the SAISC.

SAFAL Steel’s investment

uses patented aluminium-zinc technology (AZ) under licence to BIEC International Inc. Trade and Industry Minister Rob Davies cited their R1-billion project as a clear demonstration of their “confidence in South Africa as an investment destination and the maturity of our steel industry”. SAFAL Steel’s Cato Ridge facility has a capacity of 150 000 tons a year of both unpainted and painted coated coil, which is sold on to the roofing and general engineering sectors. There are plans to double these volumes in the near future. Of this, 60% of the product will be targeted at the local market and the balance exported – and exporting is the key to price competitiveness. At its opening, their facility had already created 370 jobs, mainly employing people from the local community. With most sub-Saharan countries expecting growth rates of 5% or more to 2015, steel market opportunities will be widespread. Coupled with the R809-billion that the South African government plans to spend on capital expenditure in the next three years, and a predicted medium-term increase in fixed investment in the manufacturing and mining sectors, it is clear that the future of the local steel industry is far from bleak.

What can you do? Whether you are a domestic DIY builder, a contractor, or the client’s representative in a corporate entity, don’t assume this is an issue for someone else’s conscience. Just like using environmentally friendly materials, using economy friendly ones is a process that can and will gain momentum. Be aware that competition for the lowest price can cause contractors to cut corners on materials. It’s in your best interests to ask what materials are being used and check that they are locally produced. Always ensure that the sources you procure from are licensed aluminium-zinc producers.

ed’s letter This edition of TO BUiLD focuses on a very important and urgent topic for both the professional business and the home owner – energy efficiency.

Our feature story in this edition is a fascinating account of how a team of scientists who work in a very beautiful but challenging environment pulled together to save over 20% on costly electricity by implementing both energy tariff-wise and demand reduction measures. Last winter i had the pleasure of visiting the sALT installation in sutherland myself to observe the work done by this truly amazing team. i was also blown away by the awesome scientific infrastructure that south Africa has at its disposal. As a professional photographer, i was reminded just how different the outdoors can be when taking photographs at 5h30 in the morning in a winter blizzard with temperatures hovering around minus 5 degrees at dawn. it’s been a pleasure to share these and other built environment stories with you, the readers. Please keep your fascinating and helpful media releases rolling in. We will feature your genuinely informative news wherever possible. Read on, we are packed with important tips on energy efficiency from the country’s leading authorities on the subject, including Eskom and the academics.

The real deal Clay brick’s durability and record of consistent performance over time ensures its pre-eminence in house construction in South Africa. Clay brick, as a key building material on which the mortgageable housing market of South africa was founded, has a reputation and relationship with South african homeowners that evokes a sense of worth, place and being that modern lightweight alternate building systems such as light steel frame building (lSFB) simply do not have the capacity to emulate.

Clay brick’s sense of worth is founded on its indomitable record of performance over time. The scientific reasons therefore are now better understood through a host of research that reinforces clay brick construction as the deserved benchmark for what many South africans commonly refer to as a “proper” home. Whichever way one looks at the research and

cover story the correlations in the findings in favour of double-skin clay brick walling envelopes – whether it be in respect of structural integrity, built cost, lifecycle cost, natural intrinsic qualities and their contribution to high-quality, healthy habitable space over time – new prefabricated lightweight building systems such as LSFB present a value compromise. In the first instance, the intrinsic properties and qualities of fired clay are unique in providing both thermal and acoustic comfort in a toxin-free environment, while the long-respected structural and aesthetic integrity of clay brick in construction is peerless. The recurring wide devastation of lightweight system built houses in the USA on being subjected to extreme weather events bears unfortunate testimony to this.

Superior quality assures long-term value The simplicity of bricks and mortar in design and construction; the holistic value that home consumers living in clay brick houses rightly take for granted, such as colour-fast hues and textures, solidity and the sense of security they evoke; as well as thermal mass that gives clay brick walls the natural capacity to self-regulate and moderate thermal comfort in South Africa’s unique climates, sets clay brick construction well apart from lightweight walled system technology. Research in the USA into the structural integrity and moisture resistance of different walling envelopes for houses, coupled with eight years of empirical study into the thermal performance of different wall construction types for Australian houses, bears testimony to clay brick’s superior composite offering in house construction. For example, Australian empirical research of buildings located in moderate “real world” climates found that: • lightweight building was the worst-performing in all seasons • insulated cavity brick performs the best • clay brick internal partition walls enhance indoor thermal comfort further – research found that the thermal performance of lightweight external-walled buildings improved by 20% when the internal partition walls were of clay brick. It is clay bricks’ durability and record of consistent performance over time that provides the confidence that all the natural intrinsic qualities and benefits of clay brick construction will continue well past the limited life cycle of less durable lightweight walling systems and thus elevates double-skin clay brick construction’s long-term investment value to a pre-eminent status.

Energy efficiency and low maintenance As for energy efficiency, significant research studies unequivocally affirm double-skin clay brick construction’s propensity to provide superior thermal performance of houses than comparable lightweight walling envelopes, even with higher wall R-values

The brick house Jade 909 is a new display home at Vale about 22 kilometres north-east of the Perth CBD. It is rated a carbon neutral 9-star home under the Building Energy Rating Scheme, a national scheme derived from the Building Code of Australia. It is arguably Australia’s most sustainable house, built from a very modest budget of just over 200 000 Australian dollars.

Corobrick’s Roan Satin clay face brick has a rich, earthy tone and a warm, rustic feel.

(insulation). This showcases clay brick construction’s potential to afford a lower total carbon footprint over a hypothetical 50-year lifecycle. These studies include four thermal modelling studies in both South Africa and Australia, a parametric study, an ongoing eight-year empirical research programme at the University of Newcastle in Australia comparing the thermal performance of building modules comprising different wall construction types under “real world” conditions, and the full Life Cycle Assessment (LCA) by Energetics in Australia. It is the thermal mass of clay brick that brings the “X” factor to the energy-efficiency equation in South Africa’s unique climates, with research showing that uninsulated double-skin cavity brick walling well outperforms insulated lightweight in moderate climatic zones. When insulation is applied between clay brick masonry skins in compliance with the SANS 204 deemed to satisfy standards for masonry buildings, the research demonstrates that clay brick houses provide better payback, outperforming insulated lightweight systems through all seasons in all six major climatic zones. Further to the above energy efficiency, the durability and maintenance-free qualities of face brick help to mitigate the future carbon debt that could be associated with the high maintenance, refurbishment and replacement of less durable lightweight walling. In

addition, double-skin clay brick walling in its different formats affords lower total (embodied, plus heating and cooling energy emissions) greenhouse gas emissions. These are comparable with or lower than insulated timber frame with weatherboard walling over a 50-year lifecycle. Note this argument excludes considerations of carbon sequestration, as such was not an approved parameter in the Kyoto Protocol at the time of the study. This was shown in the Energetics full Life Cycle Assessment of two house designs located in three climatic zones and four orientations – north, south, east and west.

Uniquely sustainable Clay brick used in house construction is the real deal. It is cost-effective, widely accessible and, as a face brick, presents a lowest lifecycle cost opportunity that further elevates clay brick’s pre-eminent status in house construction. Combine the thermal properties of fired clay brick with passive solar design principles and a uniquely sustainable home is at hand. It is as simple as that.

Energy-efficiency retrofit at the SA Astronomical Observatory Words: Gareth Griffiths, BSc Pictures: Gareth Griffiths Imaging

The SAAO implemented energy-saving measures to save 200 000kWh over a monitored 12-month period. In line with TO BUILDâ&#x20AC;&#x2122;s theme of energy-efficiency in this edition, the editor recently investigated a very interesting energy-conservation and demand reduction project in the heart of the Karoo near Sutherland. The South African Astronomical Observatory (SAAO) is based 120km off the n1 and just inside the

border of the northern Cape. This national research facility under the management of the national Research Foundation (nRF) operates 24 telescopes that include the giant Southern African Large Telescope (SALT) on a site located in virgin Karoo territory at an altitude of 1 800m.

Eskom power feeds the SAAO Sutherland complex including the giant SALT facility.

The inside of the giant SALT telescope is chilled from late morning to operating temperature at civil twilight.

The observatories in Sutherland are a very chilly place in winter.

The unique pollution-free and geo-stable environment of the Karoo region is ideally suited to providing high-quality astronomical observations about the universe, as used by research institutions around the globe. Of prime importance to the functioning of SALT (and the other scientific experiments) are: • clarity of the air – no dust or industrial pollution • darkness of the sky – no light pollution • extreme geological stability • reliable services infrastructure, including electricity supply and high-tech internet connectivity as well as clean, unpolluted hydrology of the ground water system to sustain residents on site. It is SAAO policy to minimise its footprint on the environment, the pristine condition of which is of huge importance to its effectiveness as a scientific research unit of the first order. Arising from this sense of duty to the environment and also a need to make operating budget ends meet, a highly commendable effort was put into an energy-conservation programme, using well-established methods. The SAAO Sutherland complex relies heavily on the grid for indoor climate control, since the burning of wood fires and gas is not permissible (in order to preserve air quality for scienctific experiments). Due to the extreme climate, the entire Sutherland SAAO complex is a large user of Eskom power and this is charged at the Ruraflex tariff. Of this, the SALT facility itself consumes a substantial amount of power due to the nature of its operation. With power bills of up to R160 000 in the colder months during 2011, staff electronics engineer Keith Browne, a member of the SAAO Energy-Saving

Committee under the direction of Phil Charles, then-director of SAAO and Darragh O’Donaghue, South African member of the SALT Board, took the initiative of introducing multiple energy-saving measures. The energy-saving project was started in March 2011 and continued through to 2012, by which time a large number of demand-side interventions had been taken. With severe limitations to capital expenditure (capex), typical of many scientific research organisations around the world, Keith Browne addressed the problem by identifying the obvious and easy fixes that did not require great capex, using available resources.

Demand-side measures taken • Optimise the use of off-peak power (at plus/minus 40c/kWh) and minimise the use of peak power (priced at close to R3.78/kWh at current high demand season rates). • Identify and repair energy loss scenarios, leaks and other wastage, hence increasing overall efficiency of the existing facilities – in both scientific, office and living space areas. • Introduce low-energy options and passive energy-saving measures.

Programmes introduced While the energy-efficiency programme at the facility is ongoing, the following measures were undertaken during 2011 and 2012: • For operational reasons, the inside of the giant SALT telescope needs to be chilled from late morning to operating temperature at civil twilight

(sun at 18°C below the horizon) when the giant telescope dome is opened. The chiller unit consumes 170-180kW, so this was set to operate at mostly off-peak times, a large reserve of glycol being cooled to optimal temperature and circulated to maintain low temperature during chillier off-times. Wherever possible, timer switches were installed to switch off non-essential devices during times of high/peak Ruraflex tariffs. The air compressors used at the SALT complex for louvre opening, tracker drive (sensitive brakes), structure air bearings on the system and other functions were overhauled and optimised. The lines from these 55kW machines are frequently subjected to thermal shock and leaks in the joints were detected and repaired as part of an ongoing intervention to ensure optimum efficiency. The operation of the air-handling units for SALT were fine-tuned. Sixteen units in total cool the dome in tandem with the operation of the chiller. Via trial and error observation and measurement, it was possible to reduce the number of these 1.5kW fans from 16 down to 6, operating from 12 noon to 6pm at any time. Solar geysers were installed at the accommodation hostel. This facility permanently accommodates visiting technicians and scientists from across the globe and needs to operate 24/7. Existing geysers and pipes were lagged. Thermal insulation was installed to the working and living areas wherever practical. A total of 19 tonnes of cellulose insulation was pumped into ceiling areas to a depth of 140mm wherever possible. The product used was manufactured from local recycled newsprint, SABS approved, and fitted by Eco-Insulation, the Southern African Association for Energy Efficiency Excellence Award Winner 2008. Houses occupied by permanent staff, the hostel, recreation area, office space and workshop space were all treated in this way. Eco-Insulation is a fire-rated green product and the supplier is a member of the Green Building Council of SA (GBCSA) and the Thermal Insulation Association of SA (TIASA). Seals in non-airtight windows were repaired and roofs were sealed wherever possible to minimise the drafts that cause a loss of heat.

• Subsequently, reducing the contracted Notified Maximum Demand with Eskom has returned capacity to Eskom and reduced the cost of electricity slightly. Additional concepts were investigated, including the use of heat pumps, PV solar panels and wind co-generation, but these were not practical either due to capex required, or environmental conditions. Double-glazing and voltage optimisation for the big equipment are among other high measures that will be implemented once budget is available.

Great energy savings recorded The SALT facility itself was offline due to grid power cuts for much of 2008 and for technical reasons during a great deal of 2009 and 2010, therefore 2007 provided the most reliable baseline consumption data. This was deemed to be suitable since no additions nor significant hardware reconfigurations had been undertaken since that year. This baseline was interpolated to 2012 conditions. Performance highlights of this new programme were: • Average energy saved: 12% per month measured up to August 2012 over the period under review • Average opex (operational expenditure) saved: 20% as of August 2012 • Payback on money invested: 19 months • ROI (return on investment) of 100% after the initial 18 months • Absolute saving over a sample 12-month period during the time under review: 200 000 kWh. As can be seen, the progressive application of energy-efficiency and energy conservation measures by the SAAO have proved to be extremely successful. A return on investment of 100% over just 18 months vs the hard cost of the installed passive measures is extremely rewarding.

Physical energy savings This graph (right) shows monthly savings since March 2011 until August 2012 over the business as usual scenario. Savings of nearly 30% were achieved during July 2012 over the baseline. Average monthly follows at close to 12%. Savings are much more significant in winter, suggesting that heating requirements for the occupied spaces have a greater impact than cooling requirements for the SALT dome conditioning.

Monthly savings as a percentage of projected (“business as usual”) cost

Additional notes: It should be noted that observations made at the SAAO in Sutherland were based on electricity supply figures supplied by Eskom. Weather conditions are extremely variable in Sutherland and may explain certain anomalies in the recorded monthly figures. The average temperature at the site is 6°C. During 2009, the basis for Eskom’s electricity charges changed from a flat tariff to the Ruraflex system, punitively loading the usage of energy during peak periods: 7–10am and 6–8pm.

The author acknowledges and is grateful for the role played by former director of the SAAO, Prof P Whitelock, for allowing access to the Sutherland facility and its key staff in the preparation of this article.

Aurecon scoops four award-winning projects This year marked the 45th south African Property Owners Association (sAPOA) convention. At the event the winners of the 2013 sAPOA Awards for innovative Excellence in Property Development was announced. sAPOA honours those property innovators, developers, owners and built environment professionals who, through the quality of their products, have contributed significantly to the enhancement of the industry (sapoaawards.co.za). “The panel of expert judges had their work cut out for them with the exceptional scope and quality of the submissions. Economic viability, the meeting of both investor and user needs, as well as architectural appeal and functionality were all considered,” explains Pieter Engelbrecht, Chairman: sAPOA Awards Committee. This year global engineering company Aurecon was part of the project teams of no fewer than four sAPOA award-winning projects: • The 1 3248 m2 Ellerines Furnishers Distribution Centre in Port Elizabeth, by Growthpoint Properties, in the industrial Developments category. • Lakeside Office Park Block 3 in Centurion, with refurbishment of the building undertaken by Growthpoint Properties, won the sAPOA 2013 Overall Green Award. • In order to cater for demand and to increase their output of engineering graduates, the University of Pretoria’s Engineering iii building and the new 550m2 foyer at the Aula Theatre took pole position in the Mixed-use category.

• One of 11 Presidential Legacy Projects as identified by the Truth and Reconciliation Commission Freedom Park recently completed Phase ii and achieved top honours in the heritage Development category. This was a joint venture between Aurecon and BEE partner Leslie Madinga Associates. “We are extremely proud to have been involved in these four stellar projects and privileged to partner with leading property developers and project teams. it is extremely gratifying that our innovative solutions for our clients have been honoured at the highest level,” comments Ermis Marques, Aurecon’s industry leader for property.

Aurecon gets high praise at the Fulton Awards Presented by the Concrete society of southern Africa (CssA) every two years, the Fulton Awards honour excellence and innovation in concrete construction and are indicative of top-achieving engineering design.

Floating in front of a wall Nowadays the bathroom is a personal refuge, a place of quiet and relaxation, with design and convenience playing an ever-greater role in this trend. The sanitary technology that creates these private wellness oases is generally concealed behind the wall. Flush plates are the only thing you get to see of a concealed sanitary installation and the cistern itself in your bathroom. Much effort goes into designing units that are both functional and attractive. The Geberit sigma50 flush plate captivates with a flawless design and floating lightness, says Geberit sa. Its sigma50 flush plate is one of the most popular and has now been reinterpreted and modernised. The dualflush arches towards the user with a discrete sweeping line while the diamond polish at the edges lends a special elegance. The flush plate itself is now rimless and looks even lighter and more elegant than before – the sigma50 seems to float in front of the wall. Versatile and exquisite with a wide range of surfaces and colours, the Geberit sigma50 flush plate offers numerous options for designing sophisticated bathrooms. The new design includes a new colour, umbra, echoing the trend for natural colour palettes in the bathroom. other finishes include white, black, pergamon, green satinised, smoked glass, white grains and stainless steel. The ever-popular customisable option is still available to add a personal touch to your bathroom design. Geberit positions itself as a pioneer and a leading company and is well known for its water-saving, advanced plumbing and sanitary technologies.

Cementing Zambian relations Backed by the government, Zambia’s National construction council (Ncc) has introduced a training programme to train SMe operators how to build urban roads using concrete block paving (cBP). Pave Zambia is a project involving the upgrading of some 2 000km of gravel roads across Zambia and cBP has an integral role to play in that programme. In addition to boosting infrastructure, the programme also creates opportunities for the local workforce. Lafarge cement Zambia PLc is conducting training using experts from South africa and France. One such expert is former construction Manufacturers’

association director and independent paving consultant John cairns, who gave a one-day seminar in Lusaka for government officials, engineers and potential paving contractors on all aspects of cBP. The Zambian government has also imported cBP production machinery from china which is being sold or leased to independent manufacturers. The cement for the project will be supplied by Lafarge cement and aggregates will be sourced locally in each province. The Zambian construction industry grew by 15.3% between 2000 and 2010 and its annual growth forecast over the next two years is 12%.

MLB Architects MLB strives for timeless architecture with simplicity as their key approach.

Wembley Square, Cape Town

THE architectural practice MLB was established in January 1987 by Xico Meirelles. He was joined a year later by Quinton Lawson, a friend and fellow architecture student from Natal University. Izak Burger joined the firm as a student in 1989 and became a partner in 1998. Three further partners – Klaus Neumann, Herman Joubert and René Grubert – were added during 2007. MLB has studios in Cape Town and a branch office in Sandton. MLB believes in timeless architecture based on contextually appropriate design. In that regard their style takes the following factors into full consideration: • brief & budget • site conditions & planning rights • sense of place & urban context • climate & sustainability • local skills & materials • cultural concerns & heritage. Although each architect at MLB remains an individual – and indeed their buildings look different – they all strive towards a timeless architecture free of fashion trends. “Simplicity is probably the key to our approach,” says partner Herman Joubert.

The Vanrhynsdorp Correctional Facility project According to René Grubert, the partner in charge of the project, the experience of working on this project has been significant. “The Vanrhynsdorp Correctional Facility has been an extremely challenging and eye-opening project due to the unusual end-user/occupants of the facility and the enormous scale and budget of the project. “Every detail is designed in such a way that it is safe and secure in an exceptionally abrasive and aggressive environment which includes limited maintenance, destructive occupants and extreme climatic conditions. Every space had to be thought through in terms of security, hiding places for contraband, safety of inmates as well as wardens while still creating good architecture.” That is certainly a tall order. “Our biggest challenge has probably been to create interesting and welcoming spaces in a facility which is at its a core a cold, closed, locked institution stigmatised by apartheid-era cruelty,” adds René. “I think we have done well in helping the Department of Correctional Services with changing the image

of what used to be called prisons into correctional facilities which are more in line with South Africa’s current national constitution”, he concludes. Hence the firm’s architectural ethos is focused fully on service excellence, based on: • good skills & experience • effective leadership & collaborative teamwork • the ongoing drive to achieve high-quality architecture.

Wembley Square project A significant MLB project in recent times in the Cape Town cityscape is the Wembley Square development by Faircape. Wembley Square was previously an inner city industrial area at the periphery of the city centre and at the edge of the devastated District 6. In the past decade the area has become one of the centres of urban renewal in Cape Town. Surrounded by residential dwellings and doublestorey warehouses, a new urban scale was introduced via the development of an eight-storey and a six-storey urban city block which clearly defines the street edges. The development created a new centre for the neighbourhood and has become an urban destination with its parking, public spaces, restaurants, retail shops and wellness facilities at street level and sectional title apartments, a gym and offices above. A second phase was added in 2011, extending the mixed-use precinct into the next city block, adding a further 16 000m2 of AAA-grade offices on eight floors and retail space at ground level. Wesley Street, the central road of the development, was converted into an urban square with attractive landscaping connecting the new quarter to the surrounding urban fabric. The public square is the main pedestrian access to the buildings, and in combination with its multifunctional hall, they become a platform for urban activities throughout the day. MLB’s approach to the architecture responded to the context of the rationalist face brick architecture of the warehouses in the area and the historical landmark of the Cape Town Archives.

quantity surveying

ASAQS Awards Since 1908, the year that the ASAQS was inaugurated, the quantity surveying profession has benefited by having a governing institution and the organisation has grown. THE Association of South African Quantity Surveyors (ASAQS) provides an environment in which professionals can learn, grow and work together to advance the techniques and science of quantity surveying. From its earliest beginnings, the ASAQS has grown to include quantity surveying professionals from every area of the construction industry – from private practice, government and quasi-government to construction companies.

QS student gold medal The ASAQS annually awards a gold medal to the best quantity surveying graduate nationwide and also announces a runner-up in that category. The winner of the ASAQS Gold Medal for best quantity surveying student was announced during the Green Vision 20/20 Conference dinner in June. Executive director of the ASAQS Larry Feinberg said that choosing an eventual winner was an extremely tough decision to make as finalists Andrew Johnson (Nelson Mandela Metropolitan University), Riané Reyneke (University of Pretoria) and Elana Malherbe (University of the Free State) were all worthy candidates to receive the gold medal for best QS student studying at a university. He then announced that Elana Malherbe was selected as winner. Elana matriculated from Pearson High School in PE with seven A symbols and was Volksblad Matric of the Year in 2008. She won the Bell John prize for most versatile student in 2010 and the Free State prize for best student in Building Contract Law in 2011. In 2012 Elana won the Dean’s prize for prestigious academic performance. Her involvement over the past three years as a caregiver to mentally handicapped children and adults at the Beudene & Bays Village Children’s Home is testament of her compassion for those less fortunate than herself. She is employed by Dill & Saunders Quantity Surveyors in Nelspruit.

Gold medallist Elana Malherbe of the UFS with executive director of the ASAQS Larry Feinberg.

Further awards Riané Reyneke of UP was the runner-up. B Tech student Graham Stuart of NMMU was winner of the gold medal for a student studying at a university of technology. At the the same event, Life Membership of the ASAQS was awarded to Dr Corné de Leeuw in recognition for his contribution to the quantity surveying profession in South Africa. A special gold medal was awarded to Corné to commemorate this achievement and also to mark his 56 years of service to the ASAQS .

QS student starts his long journey Brendan Ardagh is one of over 60 students enrolled in their first year of Construction Management studies at UCT. He aims to complete his B-degree with an Honours in Quantity Surveying and enter the profession.

QS student Brendan Ardagh at work.

How is the course going thus far? I am enjoying the course greatly. What has been very enjoyable and instructive has been the time already spent doing practical work. We worked at a volunteer build in Witsands where we helped with the laying out of gardens. Of the four first-semester courses we have done, the micro-economics half-course has been the most challenging, but very informative. Next semester comes macro-economics. My other courses are statistics, engineering drawing and construction technology. What are your impressions of the industry? I have become part of a close-knit working community. A number of my fellow students have family ties in the industry, for example a father, a sibling or an uncle in the construction industry. It is a specialist industry but does allow scope for working in different professional fields, as well as becoming involved in development projects. When will you get taught about the business end of quantity surveying? The first-year content is quite generic to the industry, with some of the classes being mixed with other B-degree faculty students. Although we are only

starting the long journey along our career paths, we’re already being exposed to industry inputs and wisdom by way of after-hours presentations by professionals who work in the industry. Will you be getting your hands dirty this academic year? There is a requirement that each student complete four weeks of training within the industry. This could be in a professional practice environment or on site. I’ve been offered an opportunity to work with the Rawson Property Group, which is involved in construction and development projects in Cape Town. I’m looking forward to this and expect to be spending a number of days on site and also in the office.

Registering as a landscape architect

To practice as a landscape architect is to be professionally registered as such by the governing body, the South African Council for the Landscape Architectural Profession. ILASA 2009 Presidential award-winning project – Thesen Islands by Chris Mulder Architects.

THE South African Council for the Landscape Architectural Profession (SACLAP) was established as a statutory council in terms of Section 2 of the South African Council for the Landscape Architectural Profession Act, Act 45 of 2000. The Council evolved out of the Board of Control for Landscape rchitects (BOCLASA), which functioned under the Council of Architects in terms of the Architectural Act, Act 73 of 1970. In subsection 18. (2) of the Landscape Architectural Profession Act, Act no 25, 2000 it states that “a person may not practice in any of the categories contemplated in subsection 18. (1) unless he or she is registered in that category”.

The role of the Council SACLAP is governed by a Council consisting of professionally registered members, representatives from the civil service and representatives of the general public, allowing for suitable diversity of interests. SACLAP strives to establish, direct, sustain and ensure a high level of professional responsibilities and ethical conduct within the art and science of landscape architecture with honesty, dignity and integrity in the broad interest of public health, safety and welfare of the community.

Industry body Another body, the Institute for Landscape Architecture in South Africa (ILASA) is a voluntary organisation registered with SACLAP. ILASA has three regional bodies: one in the Western Cape (ILASA Cape), one in KZN (ILASA KZN) and one in Gauteng (GSLA), that represent members countrywide. ILASA strives to advance the profession of landscape architecture and uphold high standards of professional service to its members and furthermore to represent the profession of landscape architecture in any matter which may affect the interests of the members of the Institute. ILASA’s Facebook page, ILASA, clearly illustrates the interactive role it plays between its member companies and the public.

Office greening A high-performing office environment requires its own green belt. A TYPICAL performance-driven organisation focuses firstly on the selection, development and retention of the right people. One of the next steps would be to create an efficient and productive environment which enables them to optimise their abilities. Compelling evidence has emerged from many studies to prove that plants form an integral part of this high-performance environment. These studies, conducted by experts in their field at universities in the Netherlands, USA and the UK, put forward convincing evidence of a direct correlation between the presence of indoor plants in the workplace and improved productivity. With precious little of the annual budget set aside for this, office plants get scant regard from management despite their presence being an essential consideration in the modern business environment. Virginia Lohr, Caroline Pearson-Mims and Georgia Goodwin of the department of Horticulture and Landscape Architecture, Washington State University, found that both active and passive interaction with plants can change human behaviours, attitude and physiological responses. During their research, participants with similar abilities undertook computer tests, some in rooms populated with plants and others without. The reaction time of the participants occupying rooms with indoor plants was found to be 12% higher. In addition to the improved productivity, those participants surrounded by plants were shown to have lower blood pressure, a significant indication of lower stress levels. The report references studies in Germany as far back as the 1960s. These asserted that employee morale improved, absenteeism decreased and worker efficiency increased when plants are added to office spaces. While the observations might have been speculative at the time, the report by Dr Virginia Lohr and her colleagues confirmed that indoor plants can, in addition to reducing stress in the workplace, improve productivity on tasks requiring concentration and quick reactions. Many factors must operate in unison if an organisation is to operate at the highest level.

The inclusion of indoor plants is a controllable item and therefore it makes little sense to ignore the opportunity of ensuring an improved physical and mental environment and a high level of organisational output.

Incremental launch solution for major Pietermaritzburg bridge Incrementally launched bridges offer lower first costs due to reduced equipment and smaller work crews as well as lower maintenance costs than any other segmental concrete bridge construction method. THE Chota Motala Road interchange straddles the N3 freeway as a major access route to the Pietermaritzburg CBD. It had been operating at above capacity for quite some time, evidenced by long delays in traffic on the Chota Motala Road (R33). Of even more concern was the dangerous situation created by the backing up of traffic on the off-ramps from the freeway, resulting in through traffic on the N3 suddenly being confronted by stationary traffic in the slow lane. After evaluating several interchange upgrade options, authorities settled on a concrete bridge over the N3 which would create a much-needed third layer of traffic at this busy interchange. The South African National Road Agency Limited (SANRAL) and Msunduzi Municipality appointed a joint venture consisting of engineering consultants Aurecon and Iliso for the detailed design of the upgraded interchange, with Aurecon responsible for all bridge work. The main determining factor in the conceptual design for the bridge was the client’s requirement that any new bridge over the N3 had to be constructed without disrupting or endangering the heavy traffic on the N3 freeway. It was for this reason that Aurecon proposed the construction of an incrementally launched bridge. “The incremental launch technique was considered ideal for this situation,” comments Aurecon project manager Hennie Niehaus. “With very little risk of disrupting traffic at any stage during construction, it met the client’s requirements in every respect.”

Choice of concrete Reinforced concrete was deemed to be the logical choice of construction material for the Chota Motala bridge as it offered the lowest initial construction cost and lowest lifecycle maintenance costs. The only alternative was a launched composite deck involving the launch of an open steel box girder over the whole length of the bridge and casting a concrete slab on it at a later stage. However, this option was not considered further because it is generally more expensive than a concrete bridge deck, has much higher maintenance costs, and the construction of the concrete top slab would have posed a safety risk to traffic on the N3, negating the main advantage of the launch bridge. The bridge was designed as a 220m long deck consisting of a single-cell pre-stressed concrete box girder with a total of seven spans varying in length between 25.15m and 36.05m, arranged symmetrically around the centre. The deck is supported on six piers, of which four are founded on piled foundations and two are founded on spread foundations.

Design challenges “The bridge has some unique design features, in particular addressing the geometry of the deck, which was particularly complex with the horizontal alignment being a 175m diameter circular curve and the vertical alignment also circular. The resulting three-dimensional circle in the space of the bridge made the launching process extremely complicated,” says Niehaus.

Incrementally launched structures Aurecon used a complex in-house mathematical computer program to calculate the launch path. A close correlation was found with a more traditional threedimensional drafting method and the tolerances on the temporary works were within 1mm to ensure that the bridge reached the correct position at the far end. “Apart from the geometric challenges, the most complicated part of the design was the post-tensioning elements,” adds Niehaus. “The bridge incorporates both concentric and draped post-tensioned cables, each fulfilling a different role during and after construction. Concentric cables limit deflections and cracking of the deck during the launching of the bridge. It is vital to limit deflections so that the launching nose is high enough to move over the temporary bearings on the next pier. The concentric cables are also used to stress the segments together once they are in position to create a continuous deck,” he explains. Another interesting feature of the design concept is the provision of access to the bridge bearings for maintenance and replacement purposes. To enable this, a recess was left in the bridge diaphragms, the deck soffit and the top of the piers.

An incrementally launched construction method involves construction of the bridge superstructure section by section on one side of the space to be spanned and then launching them sequentially into their final position. The basic idea of the incremental launching method is to prefabricate approximately 15–30m long units of the bridge under factory conditions behind an abutment and to launch the increasing bridge by sliding it, typically, on Teflon bearings into the final position without the aid of scaffolding. Incrementally launched bridges grant the owners lower first cost (due to reduced equipment and smaller work crews) and lower maintenance cost (due to additional pre-stress for launching) than any other segmental concrete bridge construction method*. Donald Bailey, a civil servant working in the British War Office during World War II, conceptualised a bold new idea for rapid bridge construction. During WWII, mostly sappers of the Allied regiments used the incremental method in launching Bailey bridges across various obstacles to enable the advance of Allied forces and restore a level of infrastructure to war-ravaged landscapes and cities.

Exceptional aesthetics

US Federal Highway Administration

Over and above its interesting design, the bridge has also achieved exceptional aesthetics. The project team, with very close input from SANRAL and the Msunduzi Municipality, took a decision that the webs and bottom slab of the bridge should be more rounded than usual and that aesthetic lighting as well as “golf tee”-shaped piers be made part of the bridge. The result is a bridge which is as elegant as it is structurally sound.

The value of innovation The cost was less than R10 000 per square metre of deck, which compares extremely favourably with similar recently constructed bridges, despite the design complexity. “Combined with the expected low maintenance cost during the lifetime of the bridge,” says Niehaus, “we believe our objective of providing the client with exceptional value for their investment has been achieved.”

Although this technique has been in use for approximately 50 years – the first post-tensioned concrete bridge constructed by launching is believed to be over the Caroní River in Venezuela in 1963 – this type of structure continues to be demanding of both design and construction. In London, the controversial Hungerford Millennium Bridge, with spans of 45m, was also constructed in this way. An incrementally launched bridge construction method offers the following benefits: • minimal disturbance of the surrounding natural or built environment • smaller and concentrated on-site space required for prelaunch fabrication of the bridge sections • greater safety factor for the workforce as work on such bridges is generally done at ground level. * Source: University of California, Berkeley

Smart insulation An award-winning cellulose fibre ceiling insulation was recently installed under the roof, covering a large area of classrooms at the Durbanville Preparatory School. SOLVING the school’s problem of excessive and expensive electricity consumption by air conditioners lay in reducing reliance on active temperature control interventions during seasonal temperature extremes. This also prepared for possible load shedding – a very real possibility given the cutbacks on Eskom’s planned infrastructure upgrade spend this year as the grid nears capacity. The Durbanville school case history file is typical of many public infrastructure buildings in South Africa. Originally built during times of cheap power supply, scant attention was given to thermal/energy-efficient building under tight construction budgets. Increasingly being specified within the built environment, Eco-Insulation is ideally suited to working public buildings due to:

• Minimum consideration of construction schedules. “A turnkey service in all sense of the word – delivery on time and on budget,” says Richard Ellis, general manager of Eco-Insulation and principal installer in the Cape Town area. • Convenience. The Eco-Insulation team worked in the background at the Durbanville Preparatory School while classes were being held. • Minimal impact. There is minimum disruption to roof infrastructure as single tiles or roof sheets are removed to facilitate access, thus minimising potential for damage. Delivery of the product in situ is via a simple pneumatic hose. From there the product flows over the surface of the ceiling and very efficiently and evenly distributes itself, sealing off the area by close to 100%. The hose

is fed from a pump that is operated from outside the building. Once installed it mats together and does not migrate around the roof space. Ellis explains that decisions for retrofitting of energy-efficient measures are currently driven by the occupants/tenants/users of the building, since they are the most immediately affected by energy cost increases. They are also the most affected by disruptions of any kind. An important part of his company’s service is the removal and approved disposal of any existing non-performing insulation product from the roof space. They have an approved method of removing and disposal of noxious glass fibre material, which traditionally presents a huge headache for property owners due to the fact that many established municipal waste facilities will not accept hazardous waste. “The insulation industry needs to provide easy, cost-effective solutions to retrofitting, and argue the

case better for passive temperature control,” explains Ellis. “In our case, Eco-Insulation is definitely the more cost-effective solution. As far as housing projects are concerned, our promise is energy efficiency, on time and on budget. We save the project manager and ultimately the property owner money – and we are SABS–approved.” Indeed, it seems as if this company has produced the energy efficiency goods. They are recipients of the Company of the Year Excellence Award by the Southern African Association for Energy Effiency (www.saee.org.za).

insulation

Save with insulation Increased energy usage is a natural consequence of economic growth and improving living standards in emerging countries. South Africa’s mounting energy crisis means we all need to think of innovative ways to save electricity in homes, factories and offices. Did you know that one of the most effective ways to save energy is to insulate the building? BUILDINGS typically account for 40% of all energy consumed in countries, yet the potential to save energy is huge. By using thermal insulation and energy-saving techniques it is possible to save up to 78% of a building’’s energy consumption for heating and cooling. Thermal insulation provides a high resistance to the flow of heat through the envelope of the building and this limits the impact of the outside temperature variations, helping to maintain a stable and comfortable living environment . Better insulation of buildings is among the most effective ways to reduce the consumption of fossil fuels used in the production of electricity, thus reducing greenhouse gas emissions.

Thermal resistance All bulk insulation materials have a thermal resistance R-value, which is a measure of their effectiveness.

The thermal resistance R-value is the ability of the insulation to resist the transfer of heat and is the most important factor when selecting thermal insulation. The R-value is determined by dividing the thickness of the material in metres by its thermal conductivity (k in W/m² ºC) The lower the thermal conductivity and the thicker the product, the higher the R-value. The Energy Efficiency Standard For Buildings (SANS 204) has been published by the SABS and will soon be legislated and incorporated into the National Building Regulations (SANS 10400). New buildings will have to comply with the minimum performance parameters, which means that insulation will have to be installed to achieve the deemed to satify R-value stipulated in SANS 204. As an example of this efficiency, over their useful life Isover’s glasswool insulation products save more than 100 times the energy consumed and CO2 emitted in their manufacture, transport and disposal.

insulation How much energy is lost? A typical uninsulated South African home loses energy as follows: • ceilings: up to 25% • windows: up to 10% • walls: up to 35% (depending on the type of construction) • floors: up to 15% • air gaps: up to 15% Buildings, including homes, typically use up to 40% of a country’s electricity. By efficiently insulating your building you can help reduce the consumption of fossil fuels used to produce electricity and thus help reduce greenhouse gas emissions. The majority of heat loss in an average house is through the walls and roof/ceiling spaces. Insulation is often considered a luxury and overlooked when building a home. However, to properly insulate the ceiling in a typical home costs less than 1% of the total per square metre building costs, and is one of the few building materials that will save you money for the lifespan of your home. A regular home loses up to 25% of its energy through the ceiling in winter and gains a similar amount in summer.

Geysers A recent study showed that it takes a 3kw, 150-litre geyser two hours to heat water. With a geyser blanket the heat will be retained for six hours, reducing the number of heating cycles, which is an easy and highly effective way of saving electricity. You don’t have to worry about turning your geyser on and off after fitting the Geyser Pack. Once installed, it passively saves money and electricity for the occupant.

Walls Do you need to insulate inside the wall? When building it is important to determine if SANS 204 requires insulation in the walls for your climatic region because up to 35% of the energy used to heat and cool a home is lost through a building’s walls, depending on the type of construction. Climatic Zone 1 Required R-value for 50mm cavity wall

Check SANS 204 Part 1 to check which geographical region your building falls under. Then, according to your region, insulation is installed according to the R-values in the table below.

Preperation: Plastered walls must first be primed and painted. On metal surfaces remove protective coating or residue. Ensure that the tile surface is dry and free from dirt and dust.

You will need:

Measuring tape

Measure the appropriate width required to seal the abutment. Make sure that the paper break line is positioned where the tile and wall meet.

Measure the length of the wall to be sealed. Cut EasyFlash and connection strip to length.

9367 GRAPHIC IMPRINT  0861 774 681

Fold EasyFlash along the release paper break line and place along abutment (do not remove release paper).

Scissors

Ladder

Staple gun

Use your ladder to access the roof space. Start the installation by measuring the distance from the area where your roof meets the outside wall (wall plate) to the top of the ridge (apex). Add 300 mm to this for the overlap that you will later make at the apex (See figure 1). Measure the total distance that you need to cover and divide this by 750 mm (width of your ClimaGuard roll) to determine the number of lengths you will need. If you have a concrete tile roof, you can simply count the number of spaces between the trusses as they should all be about 760 mm between rafter centres. Once you have calculated how many lengths you will need, you are ready to move on to the cutting stage. Use a large even area on the ground to cut the required number of lengths that you will need from your 20 m ClimaGuard rolls (See figure 2). When you have done this, roll each length into smaller easy to handle rolls and return to the roof space.

Position EasyFlash on the roof, then remove the release paper against the wall. Stick EasyFlash on the wall first ensuring a straight line along the wall.

Firmly press EasyFlash onto the wall to ensure proper contact. Now remove the release paper from the tile side and stick EasyFlash onto the clean tile surface.

Apply a connection strip which must be fastened securely with non-corrosive screws to the upper edge of EasyFlash. Apply Coverfill between the wall and connection strip.

Available from your local Coverland Depot or at Builders Warehouse. Interested in becoming an installer? Contact info.sa@monier.com www.coverland.co.za

MOENIER ROOFING _fcp.indd 1

Starting at the bottom of the rafter (wall plate) and working upwards to the top (apex), staple ClimaGuard to the insides of the rafters and the undersides of the cross battens that holds your roofing cover in place (See figure 3). You should have 300 mm extra on top which must be used for an overlap before the opposite length is installed. If you have to join two lengths, ensure that you have at least 100 mm overlap.

DIY climate and cost control The rising price of electricity is turning up the heat for many households across SA. With the introduction of RadenShield ClimaGuard, Coverland Roofing is giving homeowners the opportunity to control the climate and energy cost of their homes.

WITH summer around the corner, arguably a bigger problem faced by many households is that of excessive heat in the home. “Air conditioning causes just as much of a spike in electricity consumption as heating does – and the cost is continually going up. An insulated home uses considerably less power while remaining comfortable.” According to Coverland marketing manager Willem Grové, Radenshield™ Scientific Layering System by Coverland is a super reflective silver aluminium barrier that creates a shield against the sun’s harsh radiant heat rays. Radenshield™ is manufactured from non-woven polypropylene spunbond membrane that is laminated to highly reflective aluminium sheets, resulting in a product with high-performing insulating properties. The aluminium foil has two interesting physical properties: it is a good heat reflector and a bad heat radiator. What does this mean for you? Climaguard reflects the heat rays from the sun entering the roof, but doesn’t transfer the heat into the roof. But how do I fit this product? Must I remove the tiles from my roof? The beauty of Radenshield Climaguard as a DIY product is that can be retrofitted to an existing roof without removing the tiles. All you need is a ladder, scissors or a Stanley knife, measuring tape, a staple gun and some Radenshield Climaguard, of course. In essence Radenshield Climaguard is stapled

to the inside of the rafters in the roof cavity. Easy instructions on the pack inform you how to measure, cut and attach Climaguard to the rafters. Just be careful while working in the roof not to step on your ceiling boards, as this could cause damage and potential injury. A building with RadenShield™ installed prevents heat from entering through the roof in summer, keeping the house up to 10°C cooler. “With RadenShield, one third less heat energy enters the roof,” Grové confirms. It also retains heat during winter, which can save up to R2 500 per annum.* Noting that the price of electricity continues to increase, he says every homeowner should consider methods of reducing their usage. “The trick is really to avoid any impact on your way of life. You still want a pleasantly warm home in winter and a cool one in summer. Good insulation is one way of achieving this,” he concludes. *Scientifically tested by the Monier Technical Centre in Germany, based on a 90m² house at a regulated temperature of 22°C.

Fit-for-purpose flooring solutions The right choice of flooring is of critical importance in the healthcare sector. HEALTHCARE facilities pose significant challenges for facilities managers across South Africa when specifying a floor covering material that strikes the correct balance between hygiene, performance and design. Hygiene and cleanliness are critical to the safe operation of a healthcare building. The floor is the surface where most bacteria gather. If floors are not correctly specified or properly cleaned, the spread of disease and onset risk of contamination among patients can have devastating consequences. As a result, seamless resin materials are increasingly being used in these settings to provide an eyecatching, clean surface which is strong enough to bear superimposed loads. Not only hardwearing and durable, resin materials are easily cleaned and maintained. The material delivers a non-porous, watertight, impervious finish that does not support microbial growth or allow moisture to accumulate in joints and crevices. Resin material can be laid to coves to provide a hygienic transition between the floor and wall, helping to prevent the spread of bacteria and infection. Resin

can also be graded to meet varying slip-resistance requirements, ensuring a safe environment for staff and patients alike by reducing the risk of slips and aggravated trips. For floors that receive heavy foot and wheeled traffic, exposure to harmful chemicals, pathogens and bacteria as well as cost and colour, resin flooring is emerging as a new trend to meet these wear and tear challenges.

Healthcare applications In a recent case history involving the laying of seamless resin material, a leading manufacturer of resin-based floor and wall coatings, Flowcrete South Africa, played a key role in the construction of a medical research facility at the KwaZulu-Natal Research Institute for Tuberculosis and HIV, located at the Nelson Mandela School of Medicine. The schoolâ&#x20AC;&#x2122;s unique tower building is spread across eight storeys and represents a total footprint of 4 000m2. A total of 1 000m2 of refurbishment flooring across levels six and seven of the facility received

This product is non-tainting and non-dusting and delivers an attractive easily cleaned surface that is ideal for use in laboratories and other sterile environments. The material was supplied in three custom colourways – beige, red and orange – all of which were hand-picked by the architect and colour-matched by the supplier. Work at the site also included the installation of a water-based epoxy wall coating system, Flowseal EPW, in the same custom beige colour across both floors to deliver a seamless, chemical-resistant and hygienic finish.

A moisture problem, originated in part by the vinyl composition tile (VCT) installed throughout the facility, had caused bubbling and delaminating floor issues that needed to be corrected immediately. Flowfresh SLB, a seamless, self-levelling and chemical-resistant polyurethane concrete system, was installed across 7 000ft2 of the facility’s hallways and surgery rooms in a decorative flake finish. Tony Crowell, MD of Flowcrete North America Inc, says: “Like any of our Flowfresh products, Flowfresh SLB contains Polygiene®, an innovative antimicrobial additive that reduces the generation of bacterial population on the surface of the floor by up to 99%. One of its advantages is that the additive remains active 24 hours a day, 7 days a week, for maximum hygiene performance over the lifetime of the floor. The product also offers excellent resistance to moisture vapour transmission, eliminating the passage of water vapour to the surface, which ultimately prevents delaminating of the floor system.” Coated and sealed using Peran STC and Flowseal UV, the low-odour product system delivered a durable and robust finish to the floor and provides chemical and abrasion resistance and a UV-stable formula to retain the colour integrity of the floor finish.

Down under A flooring installation in Sydney demonstrated Flowcrete’s ability to deliver style and substance underfoot at the city’s landmark Concord Repatriation General Hospital. More than 200m2 of Kristalina resin

flooring system was installed at the newly constructed Medical Education building. The hospital was seeking a slip-resistant, decorative and hygienic flooring system that would achieve a uniform finish and represent the standards and quality of the hospital itself. The system was formulated in a special blend of coloured aggregates to deliver an attractive multi-toned grey finish. Following on from the installation of the Kristalina system, the entire surface was coated with a water-based polyurethane sealer in a satin finish. Kristalina material is solvent-free and low in volatile organic compounds (VOC) emissions, delivering a wealth of lifecycle cost and efficiency savings.

Global reach Flowcrete South Africa is part of the Flowcrete Group Ltd, a leading Kuala Lumpur-headquartered manufacturer of resin-based floor and wall coatings, including seamless epoxy terrazzo, fast-cure MMA and hardwearing polyurethane finishes as well as cementitious sub-floor screeds. The group has been in the market for more than 30 years and has manufacturing facilities across the globe.

The natural choice for green living With increasing numbers of consumers making eco-friendly choices about how they live and the impact they have on the environment, bamboo is the natural choice for green living. WHEN it comes to choosing flooring for your home or business, bamboo is the cost-effective and eco-friendly alternative to hardwood flooring. Bamboo flooring is an innovative solution for customers looking for similar physical and aesthetic attributes as hardwood but want a product that does not diminish natural resources. Bamboo flooring is a healthier and more sustainable choice that does not sacrifice strength, durability, style or quality. Bamboo Warehouse’s premium, solid bamboo flooring is as beautiful as it is beneficial to you and the environment. Strong, durable, naturally elegant and stylish as well as “green”, it’s perfect for high-traffic areas and bustling family homes. Bamboo flooring is naturally an effective insulator – warm in winter and cool in summer – and is also anti-bacterial and hypoallergenic. Due to its density, bamboo absorbs sound, minimising the “tap-tap” sound experienced with

laminate flooring. It also resists insects and is famous for its strength, beautiful colours and various grains. Not all bamboo suppliers are the same and not all bamboo is equal in quality, strength and green standards. Our A-grade bamboo flooring is imported from the world’s leading manufacturer, where the bamboo is specifically farmed for commercial use and is therefore ecologically sustainable. When it comes to choosing bamboo, make an informed choice to ensure the product you are purchasing is authentic, of premium quality, sourced from a green-certified bamboo manufacturer and that the supplier has the experience and expertise to install the product. Bamboo Warehouse is South Africa’s leading importer, supplier and installer of bamboo with offices in Gauteng, KwaZulu-Natal and Cape Town. Whether you are looking for bamboo for a commercial or residential property, our dedicated team of experts and experienced installers can provide an end-to-end solution. We also import, supply and install composite bamboo decking, a wide range of poles for pergolas and pre-wired rolled bamboo fencing. Bamboo Warehouse also supplies and installs a wide range of premium solid bamboo countertops and furniture boards which come in a variety of thickness and grain, ideal for kitchens, bathrooms and custom-made bamboo furniture. When it comes to quality, experience, expertise and innovation, Bamboo Warehouse is the obvious choice for all your bamboo needs.

windows

Aluminium windows: the smart solution Durability, design, quality and superior finishes make aluminium window products the choice material for building. ALUMINIUM windows are manufactured in various styles such as projecting top-hung and side-hung, or vertical and horizontal sliding windows. They can be used for residential, commercial or industrial applications and are available in standard and nonstandard sizes. All windows are factory glazed with glazing gaskets and beading. The growth of aluminium within the housing and commercial segment of the market is contributed to a number of points: • The ease of handling aluminium profiles • Design features are virtually unlimited and allow for creative expression that is not always easily obtained in wood and steel • The aesthetically pleasing appearance of aluminium profiles are highly sought after by all sectors of the building industry • Finishings, whether anodised or powder-coated, are applied with consistency • Aluminium is forgiving against external elements such as heat, wind, rain and salt spray, rendering a long-lasting quality look and feel and is suitable for coastal conditions • Overall finishings of aluminium such as glazing rubbers and hardware seal against wind, rain and dust and are among the best in the window openings industry.

Energy-efficient properties

carbon footprint. Hardware and the use of 4mm and 5mm glass versus 3mm and 4mm also have some energy advantage properties. Current demand in South Africa hasn’t allowed for thermal, doubled-glazed units that have energy-saving properties as known in other parts of the world. This hasn’t been embraced in the domestic housing market and is limited to government buildings such as airports and hospitals. The changeover would be relatively easy as extruding profiles for this purpose is within the manufacturers’ capabilities. Duro has increased awareness to consumers of the possible use of energy-saving glass. These products are not only more readily available but also technically far superior to previously made performance glass. “The real benefacor is the consumer,” says Barry Sacks, national contracts manager for Duro. “The durability, design, quality and superior finishes have all contributed to making aluminium products the choice material for building. Coupled to the low maintenance aluminium offers in all regions this has made aluminium windows value for money and a firm favourite among consumers.”

Energy-saving devices for homes With SA homes consuming a whopping 17% on average, peaking at 35% of Eskom power, it’s no wonder there has been major growth in multiple devices designed to help homeowners take control of the problem of rising power costs and electricity supply shortages.

www.sxc.hu

IN ADDITION, the cost of electricity in South Africa has risen by close to 24% year-on-year since 2010. It’s hitting all households in the pocket – hard. But as the old adage goes, you can’t manage something you can’t measure, so a few innovative suppliers of electronic goods have risen to the occasion with some nifty smart devices. One such device is the Efergy monitor, an easy to use yet sophisticated computerised panel. The savings vary from user to user but they can be considerable. The manufacturer reckons up to 20% savings if you use an Efergy monitor and change the way you use the electrical appliances around your home. The ecotouch energy management system allows you to check your home electricity consumption and also turn on/off your appliances remotely, using a wireless energy monitor. The new dot matrix screen allows you to check your home energy consumption both graphically and numerically. The basic model, the e2, couldn’t really be much seasier to install. Simply put the clamp onto the live mains cable in your fuse box and put the display on your coffee table! Then program the display for your own requirements and that’s it. To calculate the cost, just enter your tariff details from a recent bill onto the display. Efergy monitors are accurate to within 10%, at least. In most cases they are accurate to within 5%. Most of this variation is due to fluctuations in your electricity supply. Monitors show power information (kW), cost information, and carbon emissions (CO2). The information is displayed in three different modes: instant, history and average. Both the transmitter and the receivers work with 1.5v alkaline batteries and in addition the monitors can be powered by a DC adaptor to save on the use of batteries.

Efergy, a UK company, has appointed Ellies, a big name on the local electrical equipment supply horizon, as their South African distributor.

Public display of power savings

www.sxc.hu

A new innovation suggests that users may bring their inhouse electrical and other energy savings efforts to the attention of all occupants by displaying the building’s performance with a special “auto-play” dashboard solution.

DISPLAY options include the number of trees a user has saved for a set period, what the carbon emissions are and how consumption compares to a previous month. Parameters can be selected to showcase positive performance but also give warning of increased pressure on your system, allowing an awareness of excessive use. By positioning screens in public areas or on staff computers, the dashboard loops through a sequence of displays continuously and provides an option of

selecting the information that the user wishes to share with staff and the public, thereby creating more awareness and visibility of energy performance.

Comprehensive energy management Energy Cybernetics, the company that provides the system, offers comprehensive energy management reporting and dashboard solutions based on data collected, validated and processed through its locally developed PowerWatch energy management system.

Get green in the kitchen Words: Sam Bartlett

Protecting the planet and its resources has never been more important or relevant, and both businesses and domestic consumers need to step up to the plate. NOT only is being eco-friendly good for the planet, it also makes exceptionally good financial sense, says Danny Bryer, director of sales, marketing and revenue for the Protea Hospitality Group. Energy-saving devices are also becoming more affordable, says Bryer – the man who watches the bottom line for a company in an industry that by its very nature is a large consumer of power and water. But there is much businesses and the consumer can do to work greener in the kitchen, such as retrofitting green hot water systems, recycling of waste and installing LED lighting. Office buildings or commercial premises’ geysers that run purely on electricity are not only massively expensive, they’re also large consumers of power, says Bryer. “A solution that is being rolled out in our hotels uses the hot air expelled from the air-conditioning system to heat water. It is incredibly efficient and if one considers that in an average household a geyser constitutes almost half of the electricity usage, the savings are immediately apparent. Extrapolate those figures into the commercial or industrial space and one is talking about saving millions of rands.” With Eskom’s integrated demand management (IDM) systen, it makes financial sense both in the short and long term. In the short term companies are repaid a portion of their conversion outlay and in the long term the power savings add up to large amounts of money. “For example a 200-room Cape Town hotel offering conferencing facilities has a bar, restaurant and pool entertainment area with retrofitted LED lighting only in its public spaces. It’s a property with a lot of mood lighting

100

so the conversion costs ran to more than R300 000. Eskom then paid a 50% rebate so our electricity bills have dropped by more than R10 000 per month.”

Cooking with gas Bryer says switching kitchens over to gas and formalising recycling systems go a long way towards creating a greener environment. “As little as 10 years ago, companies may have wanted to ‘go green’ but the costs were prohibitive. We’re now in an era when alternative energy or low energy technology development is moving at such a fast pace that it is becoming more and more affordable for companies to do the right thing. “We’ve already reached the tipping point when the green alternative is the model that’ll actually save money. Internationally, many recycling industries are becoming cash cows. There are net savings to be made in energy-efficient water heating and cooling systems. Furthermore, in the not-too-distant future companies that apply energy-efficient measures will be able to claim carbon offset credits and reflect on the bottom line,” he adds. “Green isn’t just a fashionable word anymore. It’s something everybody can do. We just need the collective will to get it off the ground,” concludes Bryer.

Taps sparkle in major KZN projects Cobra Watertech’s water-saving Cobratron range of electronic taps and versatile Taryn range of taps and mixers have found favour with developers and architects in KwaZulu-Natal. THIS range was specified in no fewer than five highprofile property makeovers recently. Two Durban retail icons – the old Davenport Centre in Glenwood and Musgrave Centre in Musgrave – recently underwent extensive renovations, to the tune of R21 million and R160 million respectively. In the public restroom facilities of both centres, the existing taps were replaced with modern touch electronic stop taps and new spouts while the urinals and toilets received electronic urinal and toilet flush valves. Cobratron was also used in upgrades to Tsogo Sun’s Drakensburg Sun Hotel in the Central Drakensberg and the Cabana Beach Hotel in Umhlanga as well as the revitalisation of John Conradie House at the new Langeler Towers development in Durban.

Water-saving properties The concealed Cobratron electronic metering stop tap with soft-touch activation features a pressurecompensating, 6-litre per minute flow restrictor (maximum flow). This ensures maximum water efficiency and conforms to the Green Building Council of South Africa’s requirements. The touch-free electronic urinal and toilet flush valves meanwhile use motion sensors to detect a person’s proximity to the toilet or urinal and automatically flush the unit when the person walks away. By delivering just the right amount of water necessary, the flush valves radically reduce water wastage.

Right taps in the right place The company’s Taryn range offers the perfect look for the revamped guest bathrooms at both the Drakensburg Sun and Cabana Beach hotels. Taryn taps and mixers feature 35mm temperature and flow control cartridges, anti-lime aerators and either standard or minimalist handles. The products in this

106

range are especially designed for local conditions and incorporate quality compression-type head parts. “It was a great experience working with the Cobra team as they responded swiftly and knowledgeably to all queries raised during the project,” says Paolo Falconer of Falconer Design, who worked on both hotel projects. The final project, which will be completed in November this year, involves a substantial upgrade to The Association for the Aged’s (TAFTA) John Conradie House, which provides accommodation for elderly people in Addington, Durban. Cobra’s Xena and Capstan taps and mixers were specified for the project. The Xena range is contemporary with its clean-cut “star” handle design, while the Capstan collection is more classical with its traditional styling. Both ranges offer superior performance and are finished in high-quality chrome.

Wood innovations showcased The platform was set to showcase South Africa’s most inventive and progressive timber innovations at this year’s Institute of Timber Frame Building (ITFB) Annual Awards. To receive an ITFB Award is one of the industry’s most prominent tributes to excellence in timber design and construction. ACCORDING to ITFB president Werner Slabbert the concept of the awards was introduced in 1996 to recognise individual builders’ craftsmanship and attention to detail. “Each year builders win either a gold, silver or bronze certificate in a variety of categories to commemorate their outstanding workmanship on a particular project. A parallel award is presented to the architect or designer of the award entry”, he explains. The award categories cover: • structures larger than 120m2 and structures larger than 220m2 (category 1) • structures smaller than 120m2 (category 2) • alterations and additions (category 3) • decks, boardwalks, gazebos, etc. (category 4) • commercial buildings (category 5).

inter alia through awareness projects such as awards, the importance of quality treated structural timber against insect attack, fungal attack and biological decay throughout South Africa. Such treatment is essential in order to maintain the high value and beauty of each structure. Consequently Lonza Wood Protection, a major supplier of wood preservation chemicals in South Africa and co-sponsor of the ITFB Awards, was proudly associated with the recognition and tribute to the industry’s pioneers and by its presence highlighted the importance of the topic of timber preservation.

Award winners This year’s award winners were:

Left: House de Kock showcases an interesting use of support/decorative columns for the decks and entrance roof, which were wet-work constructed and then tiled to add another dimension to this timber-frame house. There’s a big focus on natural lighting through large windows throughout the house. Water conservation was achieved by directing roof water into a water tank to provide cold water taps in the bathrooms and kitchen. Right: The site environment for House Van Zyl proved challenging. The front poles were up to 8.5 metres and the back end of the lower floor was at ground level. Additional challenges were that the soil was hard clay with large rocks, which meant digging even deeper foundation holes for the engineer’s approval. Far right: House Wagner is located in the serene seaside village of Palm Beach on the lower KZN South Coast. The CCA-treated cladding adds natural warmth to this beautiful home. One of the challenges was not to disturb the root systems of the large protected indigenous trees on the site and to consider the branches when reaching roof height in construction.

sourced from sustainably managed plantations plays a very important role through the carbon cycle in lowering the carbon footprint of buildings. The reason is that as trees grow they absorb carbon dioxide (CO²), creating a carbon sink that produces O² and is released into the atmosphere, so sawn timber and treated poles are at best carbon neutral and in some cases even net carbon negative. “Our support of the ITFB Awards therefore falls in line with our strategy to not only promote the use of quality treated timber but also to support the recognition and awarding of excellence in timber design and construction. “As a co-sponsor with Buco and Timber iQ, we were most impressed with the quality of entries and winners in each of the categories judged this year. We would like to congratulate the ITFB organisers and judges on a professional event that did the timber frame and great wood products industry proud. Our congratulations also go to each winner and to all the entrants who supported the ITFB Awards through their commitment to uphold and promote timber innovaton,” concluded Busse. Added ITFB president Werner Slabbert: “We would like to extend our gratitude to Lonza Wood Protection for their continued support of our annual building awards project. Our longstanding relationship with Lonza in promoting the use of quality treated wood from established suppliers for all forms of timber building is an important aspect of our role as the ITFB.”

health & safety

Evolving construction regulations Regarding project health and safety, a paradigm shift is called for on behalf of all stakeholders.

Professor John Smallwood is head of the Department of Construction Management and programme director of the MSc Built Environment Programme at Nelson Mandela Metropolitan University.

THE need to professionalise construction health and safety (H&S) was identified in the Construction Industry Development Board’s (CIDB) Construction Health & Safety in South Africa Status & Recommendations report, which was released on 11 June 2009. This need was based upon anecdotal evidence and research findings that many construction H&S practitioners were not “professionals” and lacked the requisite competencies. Thereafter, in 2010, the Council for the Built Environment (CBE) mandated the South African Council for the Project and Construction Management Professions (SACPCMP) to manage the registration process. After establishing a task team the SACPCMP identified three categories of registration: construction H&S agent, construction H&S manager, and construction H&S officer. The registration of construction H&S agents started in June 2013 and the other two categories will commence on 1 August. The advent of H&S officers courtesy of the 2003 Construction Regulations was intended to remedy the lack of attention to H&S and the industry’s poor H&S performance. However, H&S is a line function responsibility and H&S officers fulfilling a staff function are unlikely to have the same effect as a committed site manager in terms of H&S. In addition, research has shown that it is not only the staff function standing of H&S officers that

128

marginalise their credibility on site, but also the nature of their qualifications and the lack of constuction management and construction H&S competencies. In essence site managers and contract managers should be qualified in the discipline of construction management and thus possess the necessary construction H&S competencies. The 2013 Construction Regulations, which will be implemented shortly, will effectively require the appointment of a professional construction manager who ultimately will be responsible for H&S on site.

Designing for constructability With respect to clients, the 2013 Construction Regulations will require clients to apply for a permit before commencing with a project, which should formalise the requirement for qualified H&S professionals among other H&S specifications, as they will need to be included with the applications for the permit. Research indicates that a large percentage of such specifications are not project specific, do not schedule “residual” risk i.e. risk remaining after “raw” risk has been mitigated by design amendments, and are largely a regurgitation of the Construction Regulations and the Occupational Health & Safety (OH&S) Act. This leads to a further issue, namely that the designer-related requirements will be more focused. Research also indicates the majority of designers do not “design for construction H&S”, a prerequisite being design hazard identification and risk assessments (HIRAs) and thus do not fulfill their requirements in terms of the current Regulation 9 and/or Section 10 of the OH&S Act. This is an indictment of the design disciplines considering that the Construction Regulations and OH&S Act have been in existence for 10 and 20 years respectively. Furthermore, should Department of Labour OH&S inspectors interrogate the design process, which to date they have not done, would designers be able to prove through a documented process that they did fulfill the requirements? In general, unlikely! Design HIRAs in turn amplify the need for focused constructability reviews in terms of

health & safety H&S, “designing for H&S” being one of 16 “design for constructability” principles. The design disciplines will now, finally, have to make the requisite paradigm shift from “H&S is the contractor’s problem” to “designing for H&S can mitigate hazards and risk” and the consequences thereof.

Collaboration between stakeholders How should the challenges be resolved? Firstly, a paradigm shift on the part of all stakeholders concerned is required. Contractors must realise that H&S is a line function responsibility despite the staff function requirement in the form of part or full-time H&S officers. Contractors will have to engender registration of their “construction managers” with the SACPCMP. H&S officers will have to be “more than an appointment”, and dedicated courses and programmes will need to be evolved. Clients will have to assess the construction H&S competencies of construction H&S agents and designers who need to assist them in terms of their responsibilities in terms of the Construction Regulations. Construction H&S agents will have to be competent in terms of construction. This may require their undertaking of dedicated courses and possibly post-graduate studies.

Designers will have to document their “designing for construction H&S” endeavours to prove the fulfillment of their obligations in terms of the Construction Regulations. Even then, Department of Labour (DoL) and other accident investigations may determine “design to have been the trigger for a series of events” that culminated in a fatal or non-fatal accident. The aforementioned amplify the need for “designing for construction H&S” to be included in architectural, engineering, interior, and landscape architecture designer/technician education. After 10 years of the 2003 Construction Regulations, the question is whether the leadership in designer tertiary education exists. Subsequent to 2003, design-related councils and voluntary associations should have developed extensive “designing for construction H&S” practice notes and guidelines, and presented continuing professional development (CPD).

Electronic life safety at UCT THE recently constructed New Engineering Building (NEB) at the University of Cape Town is an outstanding showcase of integrating innovative sustainable green building technology with human life safety systems. It was designed by SAOTA architectural practice and the principal contractor for the R150-million NEB project was Filcon Projects. Solution Station were the consulting engineers, while rational design consultant Keith Fletcher and Associates attended to the planning of building life safety aspects. Supporting the design and installation of electronic life safety and security systems for the building was FireSpec Systems, a specialised business delivering end-to-end life safety and electronic security solutions to a diverse range of commercial and industrial customers requiring protection of their people, property and assets. All round the building is a showcase of system integration. According to Cecil Meyer, FireSpec

Real desktop for real bacteria Your office desk could be dirtier than a toilet seat but don’t panic – here’s the solution.

ACCORDING to a local office workstation manufacturing company, studies show that diseasecausing microbes lurk in the most unexpected places, such as office furnishings and accessories. The average desk surface has up to 20 961 germs per 6.5cm2 and is home to 400 times more bacteria than an office toilet seat. Desks and other office surfaces are also primary habitats for bacteria that cause colds and flu. And not only do desks carry germs – they are also a breeding ground as people keep touching them and spreading even more germs. With employees eating and drinking at their workstations, the office environment turns into a bacterial minefield. What’s worse is that cleaning staff are reticent to clean desks, as they are nervous about moving people’s papers and files around. On average, only 64% of people clean their desks once a month and while wiping desks down with a disinfectant can reduce the spread of microbes, one cannot sterilise work surfaces all day.

Antibacterial coating Office furniture manufacturing company Angel Shack has found a way to counteract this by launching a desktop with an antibacterial coating for work surfaces, computer workstations, boardroom components, writing tables, office cubicle system components, cabinetry such as doors and drawer fronts, and other customised applications. The furniture company uses nano flash technology on its lacquered wood products, whereby antimicrobial chemicals physically rupture the microbe. When bacteria settle onto the protected surface, the antibacterial shield transmits positive nano charges to the germs. This inhibits the metabolic processes of the microbe cells, actively deterring bacterial growth and development. The silver ion technology provides a continuous protective antimicrobial surface where 99.9% of the bacteria are removed, thereby inhibiting the growth of bacteria. This means that microbes cannot adapt or reproduce resistant organisms.

The antibacterial coating is also safe for the user and the environment. All desks and accessories are produced without volatile organic compounds, thereby reducing indoor air pollution. The coating does not leak, migrate to a userâ&#x20AC;&#x2122;s hands or wear off when the surface is cleaned. â&#x20AC;&#x153;We see this as a major breakthrough which actively inhibits bacteria and promotes a much more hygienic environment, making it ideal not only for offices, but also hospitals, clinics, frail care, kitchens and food preparation areas,â&#x20AC;? concludes Hilton Anthony, MD of Angel Shack.

Short on skills South Africa could face an artisan crisis in the construction industry in the near future if drastic steps are not taken to implement skills development in the sector, says the MBA in the Western Cape. “IN THE next few years, the country is going to be running out of skilled bricklayers, carpenters, plumbers, electricians, plasterers and even painters. This means that soon our limited building industry skills base will disappear,” says John Matthews, chairman of the Master Builders Association Educational Trust and vice-president of the Master Builders Association of the Western Cape (MBAWC). “I think that we underestimate the magnitude of the problem, not just in the Western Cape but within the country as a whole.”

Recruiting young talent To rectify the situation and promote the skilled artisan aspect of the construction industry as a viable career path, the MBAWC has developed a DVD presentation that will be shown at schools around the Western Cape. One such school that has developed an enviable reputation in helping learners make the correct choice of future employment is Bergvliet High School, in Cape Town’s southern suburbs. Stephen Price, headmaster of Bergvliet High, believes “children need to know what career opportunities are out there. Without more school leavers entering this sector, it is going to cause a problem. We don’t want to have a lack of these skills in our country as they are vital to our economy.” Rob Johnson, executive director of the MBAWC, explains that the presentation aims to communicate to youngsters that they don’t necessarily have to go to university in order to enter the employment market – there are other options. “The MBAWC offers an apprenticeship programme, at no cost to the learner, which equips learners with the valuable skills they will need to succeed together with an internationally recognised trade certificate – at the same time enabling them to earn while they learn.”

John Matthews, vice-president of the Master Builders Association Western Cape.

Developing skills for growth Johnson says that some 50% of all the training done for the building industry nationwide takes place in the Western Cape, which has a proud tradition of producing skilled people who have worked on major projects all over southern Africa. It is noteworthy that many of the successful businessmen and women in the construction arena started in the hard skills sector and worked their way up and that certain trades such as plumbing, carpentry and joinery, tiling and roofing lend themselves to artisans who go on to become entrepreneurs. “We want school leavers to realise that the opportunities in the industry are endless and that one can get to the top without having to be an academic,” concludes Johnson. While business has been criticised for not participating in skills development by Minister of Higher Education Blade Nzimande, who has requested that they partner with government in producing a skilled workforce, the Master Builders Association seems to be showcasing just what the construction industry can do if they set their minds to it.

Flour silo becomes functional space at the Old Biscuit Mill

historical building, the marks of an evolution of the building through a new generation.” To maximise daylight inside the building a translucent internal wall system was designed to allow light to penetrate throughout the building. More natural light minimises energy usage in daytime and is thus more energy efficient.

Kristof Basson Architects

The Old Biscuit Mill, Woodstock’s renowned creative retail space, recently welcomed a R10-million, sixstorey transformation of its iconic silo. The tower was previously the functional mainstay of the original flour mill, a storage space for grain, but after a complex renovation by owners Indigo Properties, it is now the home of the Cape Town Creative Academy (CTCA), Cocoa Fair chocolate factory and Luke Dale-Roberts’ penthouse restaurant, The Pot Luck Club. Architect Kristof Basson, who was responsible for the 2005 redevelopment of the Old Biscuit Mill, was once again appointed to redesign the silo. As with the previous Old Biscuit Mill development, Basson felt strongly that the historical elements and style should be retained as far as possible but did not shy away from introducing contemporary elements – as evidenced in the sleek glass and steel lift and the new canopy that has been installed as a weather measure for the weekly Neighbourgoods Market. Says Basson; “All new work on the building has been done in different materials to differentiate between the new and the original structure. It is our vision that each intervention should not be hidden, but should be seen as an added layer to the

The demolition of the existing internal concrete walls of the silo was a complex challenge focused on preventing the external walls from collapsing. As the first concrete blocks were cut out and lowered to the ground by crane, it was discovered that there was less than half the amount of steel reinforcing in the concrete than was originally estimated. Experienced structural engineers Kantey & Templer Consulting Engineers (K&T) were on hand to stabilise the site. Chris von Geusau, MD of K&T says, “The old reinforced concrete silo structure was some 70 years old and we needed to secure it with internal steel bracing struts to demolish the internal concrete walls. The new structure was then built up floor by floor, using steel beams with precast concrete flooring, all lifted over the top walls by crane. “The type of structure afforded the project architect an industrial look of steel and concrete that suited the intended aesthetics of the new space. The steel and concrete roof over the silo is supported by steel portal frames anchored to the side walls. The project took on a life of its own with a positive spirit amongst all those involved to achieve something different that would attract the attention of all those who visit the venue.” concludes Geusau. Lyle Raatz from GR Building & Steel adds, “When we were appointed to this project, we knew we were delving into the unknown but it was made extremely challenging in that we had to accommodate live businesses at the bottom of the silo and on either side, so everything demanded a very high level of communication and planning. It will forever be one of those projects that we can be proud of.” Barry Harlen, director of the Indigo Property Group concludes, “It was a tough project but one that has been well worth the effort. The end result is a space like no other – the bird’s eye view of Woodstock from the restaurant is a new perspective on Cape Town and the Creative Academy represents a new perspective on design through their focus on trans-disciplinary tertiary education. All in all, an exciting addition to the tenant mix and great company for the silo’s resident chocolatiers.”

Cbp used in Shovagakula paving project Precast concrete block pavers (CBP) and kerbing are being used to construct safe, attractive and durable pavements in Olievenhoutbosch Ext 36, a suburb of Centurion, for both pedestrians and cyclists. KNOWN as the City of Tshwane’s Shovagakula (Easy) Paving Project, it is being run over three years in several phases and aims to encourage the use of bicycles in place of cars for travel within Olievenhoutbosch. Phase 1, which was begun in April and completed by the middle of June, involved the construction

of pavements 2.2m wide and 1 600m long using 50mm bevelled pavers as well as Figure 10 and 12 concrete kerbing supplied by Concrete Manufacturers Association (CMA) member MVA Bricks. Construction involved compacting in situ material to 90-93%, adding and compacting a 150mm layer of G5 mixed with 4% of cement, and topping that with 20mm

of river sand. Once the pavers were laid, they were covered with plaster sand to fill the joints between the pavers. The surface was then swept and compacted to form an attractive and hard-wearing surface. The terracotta-coloured pavements were edged with a header course of charcoal pavers which were also used for decoration strips at every 5m.

Advantages of pavers Interlocking pavers solve a number of problems of cast concrete pavements. They are appropriate for any paving application including patios, pool decks, driveways and walkways. Because pavers are individual units or “bricks,” the natural joints between each paver will “give” with pressure, expansion and contraction, eliminating the cracking inherent to conventional asphalt and concrete pavement. One of the biggest advantages of pavers is that if a repair ever does become necessary, pavers are manufactured to be uniform and can therefore easily be replaced without leaving ugly patches or scars.

Skills training The main contractor on Phase 1 was MK Brick and Earthworks, owned and run by Nathaniel Kgobe. Kgobe says 35 people were deployed for the execution of Phase 1, 28 of whom were unskilled members of the local community. “We trained them in all aspects of CBP surfacing including the preparation of the sub-base, the actual laying of pavers and the installation of kerbing, and they have acquired skills which they can use on other projects of this nature.”

cement & concrete Energy management With competition increasing in Africa’s cement and concrete industry it’s becoming ever more important to keep down costs in order to stay competitive while maintaining profit margins. With electricity consumption being one of the most significant costs incurred in the cement, concrete and construction industry, strategic energy management practices provide a viable solution to manage energy costs and safeguard margins. In the past six months alone, market share of imported cement, primarily from Pakistan, has grown by 0.6% in Africa. One of the highlights of the energy management session was a presentation from Egmont Ottermann, group energy manager at PPC, who offered insights into industrial energy efficiency improvement for energy-intensive users. Ottermann likened the situation the industry is now facing to that of a “perfect storm” involving the triple challenges of: • energy • debt • carbon. He explained that while energy costs in the past were predictable and manageable through technology improvements and efficiency, the expected increases in energy costs are likely to outstrip the industry’s ability to adapt while doing business as usual. He added that most energy efficiency in the industry is achieved through changes in how energy is managed in an industrial facility, rather than through installation of new technologies, a point he demonstrated graphically. Energy management systems, said Ottermann, provide a framework for understanding significant energy uses with action plans for continually improved energy performance and a structure and organisational framework to sustain energy performance improve-ments over time and change of personnel. “Action plans require training, design, procurement, communication and organisational change. But is top management really committed, and will they support the system?” he asked.

Benefits To illustrate the principles mentioned, he used a recent example within the PPC Group – that of the programme rolled out at PPC De Hoek. The facility completed its first audit in February

Building our country one stone at a time The Aggregate and Sand Producers Association of Southern Africa (Aspasa) is a voluntary producers’ association that helps to improve the quality of aggregates produced by its member companies for construction projects around the country. THE role Aspasa plays is critical considering that almost every man-made structure relies on aggregates for strength and stability. In fact, construction aggregates are the primary ingredients of all concrete structures and foundations (80% of concrete is aggregate), as well as being the single most important ingredient used to build our roads (94% of a road is aggregate). “Aggregates and sands used in construction projects are naturally occurring minerals that are mined by a specialised sector of the mining industry in South Africa, mainly from quarries. Government strictly regulates sand and aggregate quarries due to the importance of obtaining a reliable supply of quality materials. It also aims to ensure that the minerals and materials are removed in a manner that is sustainable and protects the rights of workers, as well as the environment and surrounding communities,” explains Aspasa director Nico Pienaar.

Responsible association “As a private sector association representing producers in the industry, we uphold these aims. In addition we strive to create an economically viable industry with good interaction between all parties involved, from the industry as well as the relevant government departments and other stake holders,” says Nico. “Our focus remains largely on creating an environment that is fair and equitable and gives our members space to manoeuvre and to make a good living. On the other hand, we expect members to comply with all relevant legislation, as well uphold the strictest standards in quality, health, safety and environmental issues. Annual audits are in place to assist members to achieve set requirements and also to ensure that they comply with the relevant legislation.

156

“In addition to this Aspasa supports the adoption of a proactive strategy to foster change and to encourage black economic empowerment and transformation in a sustainable and economically sensible manner,” Nico concludes. For this reason Aspasa subscribes to the aims of the broad-based black-economic empowerment charter for the mining industry – in particular, the pillars of transformation related to: • human resources development • employment equity • encouraging greater community participation and development • promoting greater procurement from HDSA companies • encouraging greater HDSA ownership and • participation in and facilitating of beneficiation.

Benchmarking water & energy usage The Green Building Council of South Africa (GBCSA) has launched a pilot Energy and Water Benchmarking tool which allows property owners to see how their building’s consumption measures up to industry norms.

Reducing consumption The pilot tool incorporates a 10-point rating scale that is based on the relative performance of buildings with respect to their peers. It contains formulas that allow a building’s consumption to be normalised according to the methodology developed, taking occupancy and regional climatic differences into account. “This tool will be of use to our customers in assessing and reducing their consumption of electricity and water. Eskom manages office accommodation of about 1 million m2 and will certainly be using the tool to track and reduce our own consumption too. We look forward to seeing the trends and findings which emerge from usage of the tool,” says Eskom senior general manager Andrew Etzinger.

Tool development The development process for this tool involved surveying the performance of almost 350 office buildings located throughout South Africa and analysing and benchmarking the data. Building owners need to have at least one year’s worth of energy or water data to input into the benchmarking tool in order to assess performance. ww.sxc.hu

A significant database UNTIL now the GBCSA has focused on the certification and rating of new buildings to ensure a more sustainable built environment going forward. However, new buildings only account for about 1%-2% of the average property portfolio and to truly minimise the impact of buildings on the environment, existing buildings must be considered.

Tenants also benefit The tool could also prove useful to prospective tenants as the ratings assigned to a building will give a good indication of consumption and efficiency within a building. GBCSA technical executive Manfred Braune says, “This tool is powerful in assisting property owners to decide which properties to retrofit or sell, as well as being a useful marketing tool for star performers in a portfolio.”

Braune notes that the number of buildings surveyed means that this is probably South Africa’s most significant survey and database of its kind. Approximately 10 property owners with sizeable portfolios throughout South Africa submitted data, which was gathered over a year, and then further analysed. The benchmarking tool is a key input to the GBCSA’s Existing Building Performance rating tool, which is currently under development.

Holistic energy management: the ultimate goal Words: Rip Wyma, Pr Eng ENERGY efficiency has become a significant item on the South African corporate agenda. Some building projects are implementing Green Star energy ratings while many are just beginning to take steps to reduce energy demand and others have not yet begun. There are many methods available to the organisation to begin energy consumption reduction. However, these should ideally not be implemented in isolation without a “big picture” view of an organisation’s overall energy usage patterns. Improving energy efficiency is a journey, and it pays to remember each of the steps taken should work towards the ultimate goal – holistic, integrated and allencompassing energy management solutions. The drive towards improving energy efficiency is due largely to the increasing cost of energy. Cost-saving is also augmented by increasing social and environmental awareness, as well as by legal requirements. These currently include the need for all Johannesburg Stock Exchange (JSE)-listed companies to include sustainability and carbon reductions in corporate reporting. However, there are several other laws in the pipeline around energy consumption and carbon emissions, and organisations are beginning to gear themselves towards meeting these criteria as well.

Simple steps for quick gains Increasing pressures are leading large corporates particularly to examine initiatives for improved energy efficiency. Green Star energy-rated buildings are one way to achieve this, with additional benefits to cost savings on energy promoting a green image. However, such buildings are expensive to construct and are best suited to greenfields developments, an option which is not always feasible. For most organisations, energy efficiency involves optimising energy consumption in existing buildings. This includes areas such as heating, ventilation and air-conditioning (HVAC), geysers,boilers and lighting. Lighting is one area where quick gains can be made. This is often the first area that facilities managers look at when aiming to improve energy efficiency. LED lights offer up to six times reduction

164

in consumption vs CFLs, while CFLs offer a six times reduction vs incandescents. Lighting is also often left on unnecessarily, particularly after hours, wasting significant quantities of energy. Central air conditioning systems are often not optimised for efficiency during commissioning, and lack of routine maintenance often causes them to run inefficiently. They are also often left to run unnecessarily after hours, wasting power. It is possible that the days of console units all over the building are numbered with huge amounts of cool air available on an annual cycle, as long the system is designed for an AHU (an air handling unit, a return air fan with full damper control). However, by simply ensuring that heating and cooling are optimally tuned and well maintained and that these units and lighting are switched off when not needed, organisations can save up to 30% on their energy bills.

Integrated approach However, if these manual initiatives are left to human error they will often fail. Energy audits need to be conducted to identify areas for each individual building where improvements can be made, and automated controls should be put into place for areas like lighting and air-conditioning to ensure compliance. However, carbon footprint is not just about kilowatt hours of electricity usage, but includes water consumption, fuel consumption, transport, travel and more. Meeting the challenge of reducing carbon footprint all around requires an integrated approach to energy management that gives organisations a complete picture of energy consumption across all areas as well as carbon footprint.

Eskom saves a shedload Pictures: Gareth Griffiths Imaging and Selected Energy

Partnerships between Eskom and South Africa’s business owners and householders – energy efficiency campaigns, technology exchanges and rebate programmes – have reaped demand savings of 589 MW over the past 12 months. All these initiatives are designed to identify and promote increasingly efficient ways to achieve lowering the demand for energy, maintaining the balance between supply and demand on the national power grid, inculcating financially savvy energy usage, and reducing energy costs for electricity users in all sectors of the South African economy – from private homes, guest houses, residential estates, factories, manufacturing plants and mines to retail chains, car dealerships, financial institutions, commercial properties, office parks and farms. Broadly speaking for the purposes of this article, Eskom’s integrated demand management interventions are split into the two sections, namely business and residential.

Business sector Eskom’s four rebate programmes – the Standard Product, Standard Offer, ESCo Model and Performance Contracting – make a huge contribution

166

towards offsetting the capital outlay to implement energy-efficiency retrofits by businesses across the board in the commercial, industrial and agricultural sectors. Since 2005, demand savings of 1 031 MW have been achieved in these sectors as a result of energy-efficiency projects funded through the rebate programmes. Placing this into an “easy-to-comprehend” context, 1 031 MW would be enough to power nearly 6 800 average-sized office buildings, or nearly 14 averagesized towns, such as Rustenburg in the North West Province. • Standard Product is aimed at small- to mediumsized businesses and provides funding for the fitting or retrofitting of off-the-shelf products such as energy-efficient lighting systems, solar water heating systems, heat pumps, and energy- and water-saving shower heads.

issue 9 www.tobuild.co.za

energy • Standard Offer supports funding for energyefficient lighting systems, building management systems, hot water systems, industrial and commercial solar water heating systems, and process optimisation systems. • The ESCo Model offers funding for the implementation of large retrofit projects and is aimed at Energy Services Companies (ESCos) that specialise in identifying opportunities for achieving reductions in electricity consumption and formalising projects as a basis for establishing a four-way partnership between Eskom, the business owner, an ESCo and a measurement and verification expert. • Performance Contracting supports verified bulk energy savings across multiple sites and technologies by contracting with a single project developer.

Residential sector Saving energy is imperative in the residential sector where homes – from flats, townhouses and cluster houses to stand-alone houses and residential estates – use 17% of South Africa’s electricity, a demand for energy that increases to peak at 35% between 5:30 pm and 7:30 pm, a huge jump that puts severe strain on the power supply during the two most critical hours of the four-hour evening peak. To date, most energy savings in the sector have been achieved through the implementation of two nationwide technology exchange initiatives: the CFL Exchange and the Switch and Save Residential Mass Roll-Out programmes. In the case of the CFL Exchange programme – the biggest residential energy efficiency roll-out of its kind in the world – Eskom-accredited installers go doorto-door in neighbourhoods in towns and cities across South Africa to replace energy-intensive incandescent light bulbs with CFLs (compact fluorescent lamps). Since 2005, demand savings of 2 287 MW have been achieved as a result of the installation of more than 55 million CFLs in homes nationwide. Once again, to put this into context, 2 287 MW is enough to power more than 3.8 million 600W fridges – more than a third of all fridges in the residential sector if we assume there is one fridge at work in each of the estimated 11 million households in South Africa. The Switch and Save Residential Mass RollOut, Eskom’s second large-scale energy-efficiency programme in the residential sector, provides

homeowners with a range of free energy-saving products – the “energy-efficiency basics” that assist to optimise energy usage in the home while at the same time contributing to reducing demand for electricity in the sector. These products include CFLs, LEDs (light emitting diodes), energy- and water-saving shower heads, and geyser and pool pump timers. Between inception in 2012 and March 2013, a relatively short period of time, the Switch and Save Residential Mass Roll-out Programme reduced strain on the national power grid by 213 MW. Eskom’s third big energy-efficiency initiative in the residential sector is rebate programmes that support the homeowner with funding to replace energyintensive electrical element geysers with either highpressure solar water heating systems or heat pumps. The solar programme has been running since 2008 and the heat pump programme since 2011. More than 330 000 solar claims have been received and nearly 11 016 heat pumps have been rebated to date. Going forward, the solar programme will be implemented by Eskom under the umbrella of the government-led and -branded National Solar Water Heating Programme.

Into the future Andrew Etzinger, senior general manager of the Integrated Demand Management (IDM) department at Eskom, says, “Eskom’s energy-efficiency campaigns, technology exchanges and rebate programmes have been successful in lowering electricity usage in South Africa and as a result assisting householders to reduce monthly energy costs and business owners to lower costs and improve bottom line earnings. “Since 2005, demand savings of 3 587 MW have been achieved as a result of all of Eskom’s energyefficiency programmes and projects in the residential, commercial, industrial and agricultural sectors. This success propels Eskom to keep on identifying and developing new energy-saving mechanisms and initiatives as a measure to establish financially smart energy usage as a business norm and a way of life for society as a whole.”

New exterior cladding system from Weber ETICS (external thermal insulation composite system) is a thermally insulating, protective and decorative exterior cladding system which consists of a series of engineered EPS panels and a waterproof membrane, together with a reinforcing cement base coat and a mineral or polymeric finish plaster, all of which combine to exceed the R-values set out in SANS 204.

Property owners may have little control over the increasing cost of energy, but they can meaningfully reduce the amount of energy required to control the climate in homes and offices. Correctly installed, Weber ETICS will reduce energy wastage and increase the level of comfort by reducing heating/cooling bills.

Plan ahead for an energy-efficient home or office

Installation methodology

In today’s economic climate the importance of a properly insulated home or office cannot be overstated. With further energy-related price increases on the horizon on top of the already unaffordable price of energy, the insulation properties of Weber’s ETICS system will prove to be ever more telling.

168

Weber ETICS can be fixed to the existing or new substrate – brick, block or LSF (lightweight steel frame) – using Weber-engineered EPS panels with specialised fixings. Weber base coat with mesh reinforcement is applied to the EPS and once cured a final decorative render is applied to complete the system.

Weber’s decorative render is available in a variety of colours, sizes and textures all ready-mixed and matched to the client’s specification. Weber’s decorative renders are applied by trowel and are highly waterproof and durable.

Save in the long run While ETICS can be costly to install, it boasts various advantages such as improved air tightness of the building and also substantially increases the thermal performance of the building. The savings achieved far exceed the initial cost of installation. If ETICS is applied in conjunction with an LSF structure, further reductions in heavy design loads on the edge of slabs can be achieved, which in turn

can reduce the need for “up-stand” beams. This is an important factor to take into account when determining the savings that can be achieved using Weber ETICS, as it only weighs 60kg/m2 as opposed to double brick work that weighs approximately 450kg/m2. Savings are also achieved on installation time when using Weber ETICS and this can drastically reduce the build time: • lightweight • speed of erection • minimal wastage • increased GLA (gross leasable area) • increased thermal performance • reduced heavy design loads on structure • no need for painting • render comes tinted in colour specified by client • 10-year guarantee on Weber’s ETIC system • saving on scaffolding • no craning of materials required • flexibility in design.

Piping for a big game estate development A specialist developer of game lodges, elite estates, game reserves and commercial property in South Africa and eastern Africa recently collaborated with a leading infrastructure and pipe system supplier on the bushveld development Leadwood Big Game Estate.

WITH over 35 years of experience in the property development industry, Jordan Properties wanted to create a development that would bring African wildlife to the public. Leadwood Big Game Estate, an innovative and pioneering development in the Hoedspruit area, is 984 hectares in size and offers a 32-bed lodge as well as 94 one-hectare free-hold stands for an exclusive primary residence or holiday home. Jordan Properties places a large emphasis on conservation and sustainable development, and Marley Pipe Systems’ matching integrity for sustainability and innovation made them the preferred piping supplier for this elite estate project. Marley Infrastructure, a division of Marley Pipe Systems, initially supplied over 9 500m of high-density polyethylene (HDPE) piping to Leadwood Big Game Estate. HDPE pressure pipes were ideal to create the infrastructure for the water supply in this development, having taken flow, pressure, bending, and various other factors into the design considerations of the pipes to ensure the provision of a long-term, sustainable, and environmentally-friendly solution. Ian Nortier, area manager for Marley Infrastructure in the north-east explains, “Supplying the material for

the Leadwood Big Game Estate development has once again proven that Marley Pipe Systems’ involvement in these one-of-a-kind-projects plays an essential part in meeting our customers’ expectations for their envisaged developments – not only by supplying highquality products, but also by ensuring that they receive technical backup and after-sales service of the highest standards that will last for the duration of the project.” Says Patrick Jordan, general manager for the Leadwood Development Company and Jordan Properties, “The high-quality products from Marley form the backbone and supply structure for the entire water system in Leadwood Big Game Estate and we have received only good feedback about Marley’s products from contractors.” The Leadwood Big Game Estate development is currently on sale with approximately 50% sold out and a total of 70 stands serviced with both water and electricity.

Product compliance certification for thermal insulation Thermal insulation products make an important contribution to energy conservation and saving energy resources. The broad range of thermal insulation products on the market has a scope of application as various as their characteristics. THE Thermal Insulation Association of Southern Africa (TIASA) has established the TIASA Product Compliance Certificate (PCC), giving TIASA membermanufacturers the opportunity to convince users and consumers of the quality of their products. This meaningful certification gives the manufacturer a market advantage against his competitors. The TIASA Product Compliance Certificate for thermal insulation products shows not only that the manufacturer fulfills the legal requirements of the National Building Regulations but also that all characteristics given in the designation standard of the product are tested and surveyed by neutral, independent and competent bodies. This improves the confidence of users and consumers throughout South Africa and Africa.

Additional assurance for users The TIASA PCC is the result of a stringent compliance with testing in accordance with South African National Standards (SANS) and the voluntary SABS Certification scheme (SABS Mark of Approval) or Agrément Certification. The TIASA PCC provides users with the clear and simple message that the product complies with SANS and the National Building Regulations (NBR). The TIASA PCC for thermal insulation products will assist users to differentiate between products conforming to the legally required minimum requirements of the NBR and SANS compared to products that have not been tested and are non-compliant. Furthermore certain TIASA manufacturers operate a product-related factory production control system taking into account the elements of the EN ISO 9000 series.

Testing and assessment Only thermal insulation products that were successfully tested by an accredited South African National Accreditation System (SANAS) testing laboratory

178

and are in full compliance with the relevant product standards are certified by TIASA.

Certificates and registrations Designers, project managers and contractors are advised that all compliance certificates are listed on a register on the TIASA website (www.tiasa.org.za) under “Technical Information” sub-section “Technical Publications”. The TIASA PCC register reflects: • the certified/registered type of insulation and the manufacturer • the registration number of the certificate/ registration • the period of validity of the certificate/registration. Note: Products which are non-compliant and certificates which are expired or suspended are not listed.

Embracing the thermal insulation marketplace TIASA promotes the benefits of insulation. Although providing a service to all industries, its initial focus is the development of its products and services for the building and construction industry with specific attention paid to sustainable energy-efficient affordable homes. It is the only organisation that embraces the entire thermal insulation marketplace, including manufacturers, distributors, contractors, specifiers, designers, architects, energy service companies, national and local government, utilities as well as end users in the domestic sector.

A walkabout in Woodstock A walk through the rejuvenating design quarter of Woodstock reveals many interesting showrooms, shops and studios. Pictures: Gareth Griffiths Imaging

Derrick Baard of Purespace Design believes that local sourcing and design is the way to go for interiors and furniture. His showroom reflects a vivid interest in and commitment to the subject.

182

APART from the renovation of the Silo at the Old Biscuit Mill (see page 143) in Albert Road, there is a great deal of evidence that Cape Town is indeed emerging as the Design Capital of the World 2014, both in word and deed. In one studio/showroom, design entrepreneur Derrick Baard shows his eye-catching designs of locally made interior décor items and furniture. “I would have to say indigenous timber is preferable over and above locally grown timber, since not all locally grown timber is good for local conditions,” he says. “You see, some locally grown species are invasive. Indigenous timber using local labour is probably the best route to follow from a sustainable and economical point of view. The only way indigenous forests will survive is if value is given to the resource for what it is, enabling it to exist in its own environment and being mowed down for short-term gain, or to make way for agriculture or similar.” “We need to provide local labour in order to support our local manufacturing sector. If products purely come down to price, we’re in trouble. There’s no point in getting something made at half the price and losing thousands of local jobs. If you destroy local manufacture you destroy the whole value chain in the long term. It’s just not sustainable,” he adds. Indeed, Derrick’s creations are a masterful expression of indigenous design thinking, from paper-clad vases made by indigenous communities in Gauteng to classic furniture made from African iroko wood cultivated in Knysna. Derrick’s studio, Purespace, has undertaken many a memorable interior design project, including the Fossil retail chain and L’Ormarins Motor Museum of classic and collectable cars owned by the Rupert family.
