THE STATE OF BUILDING IN OUR NATION

After the accounting exercise that was President Cyril Ramaphosa’s State of the Nation address on 9 February, we are left with many unanswered questions. Rather than a clear, concise plan for the short, medium and long term, or practical solutions to our politically caused energy crisis, we got palliative measures in the form of complicated ministerial portfolios and yet another new ministry headed by a highly paid Minister of Electricity. We also got a declaration of a state of emergency.

For many, the speech was far from reassuring.

So what should we be doing? Where possible, it is time to apply pressure and expand the conversation. Ideally, a crisis such as this one is also an opportunity to “build back better”. Smartening our grid and finding alternative technologies to load-draining

MBA RESPONDS TO SONA

Master Builders South Africa (MBSA) welcomes President Cyril Ramaphosa’s open and determined recognition of the core challenges facing South Africa today, as we push towards recovering an economy that works for all.

MBSA acknowledges the sound approach to addressing the energy crisis, which sustains the five key interventions identified in 2022:

1. Fix Eskom’s coal-fired power stations and improve the availability of existing supply.

2. Enable and accelerate private investment in generation capacity.

3. Accelerate procurement of new capacity from renewables, gas and battery storage.

appliances are strategies that have to form part of any energy solution.

Co-ordinating private-sector investment with a national energy plan is something that should have begun in earnest already. A full energy system approach has the potential to change the assumptions which currently constrain us by causing us to focus exclusively on power generation. What we need are creative consultation, engagement and the generation of as many options as possible to make our individual choices wiser and our collective choices smarter. While we all endure this periodic darkness, our solutions must be made in the light constructive engagement.

The way to protest our current situation is to force new and better conversations that integrate our current, personal energy investments into the smartest evolving solution possible.

4. Unleash businesses and households to invest in rooftop solar.

5. Fundamentally transform the electricity sector to achieve long-term energy security.

Seeking greater engagement with associations and organisations active in SA’s construction and infrastructure sectors is perhaps the most important of MBSA’s 2023 strategy. Likewise, we urge government to get the full advantage of engaging with us, and other strategic private-sector structures, to ensure optimal planning, consultation and co-ordination of the wealth of skills, knowledge and experience these represent.

Partnering across the public and private sectors now will shape our future profoundly and with the urgent need to solve the present crisis being such a shared and common goal, it may also yield an uncommon basis for co-operation and trust.

ALL STATES AFRICA CONCRETE EQUIPMENT–GROUND-FLOOR OPPORTUNITY

Expanding the range of opportunities for contractors is one of the most important undertakings in our current economy. All States Africa Concrete Equipment (ASACE) was established with this principle in mind and owner Sven Schutte has built the company from its early days as a small agency to the wellstocked responsive business it is today on that very idea.

Schutte’s own occupation as a specialist contractor in concrete finishes has imbued his work as the South African representative of All States Concrete Equipment, with an edge for realising quality for cost in the local market. The company’s impressive inventory of specialty concrete flooring

equipment is underpinned by a passion for realising financial, operational and practical solutions for every client, opening the door to a market once reserved for larger players and subcontractors.

“All markets have their own peculiarities and South Africa may have more than some. In the concrete flooring and finishes segment, there’s definitely space in the market for specialist contractors with the granular knowledge and equipment needed for large projects,” he says.

ASACE’s warehouse is continuously stocked with leading global brands, including Ligchine’s range of boom and drive-in

screeds and Betonelli’s innovative power float technologies. The company’s offering of global brands are also fit for local market conditions. “To really benefit from these products in the South African market, it’s essential to be a true partner to our customers,” explains Schutte. “The first step is the most important one: making contact. From there, we work very steadily with our customers, understanding their businesses and goals and developing a solution that’s affordable and will give them not only the technical results, but the best shot for projects that may once have seemed out of reach.”

SOUTH AFRICAN BUILDER MARCH 2023 04 COVER STORY
(Left): All States Africa Concrete Equipment's warehouse is continuously stocked with the equipment you need to confidently deliver on today's opportunities. (Above): These leading brands can be in your hands today, backed up by the training and service needed to keep your customers coming back.

FROM SPECIALTY CONTRACTORS TO CONSTRUCTION COMPANIES

With the right selection of tools and machinery, coupled with the knowledge and support of ASACE, contractors can develop specialty services at competitive rates and build the businesses on results and reputation.

The benefits of owning large screed and power float equipment include the ability to make a complete offering, ruling out the nuisance factors that sometimes develop between contractor and sub-contractor. With ASACE’s network of machinery and skills, the ability to take full control of projects is one step closer.

FLAWLESS FLOORS MINUS THE ISSUES

Schutte’s vision of concrete flooring is the right equipment, tools and focus at every step of the process. A perfectly level and flat floor with the required finish is well within reach.

“A clear example of getting something right the first time is the difference between floor levelness and floor flatness. The expense and structural risks of grinding uneven floors or applying self-levelling screeds, resulting from focusing too much on floor levelness and not enough on flatness, is a prime example of unnecessary and complicated corrective work,” he explains.

RESULTS ARE POSSIBLE TODAY

The benefits of partnering with

ASACE are immediate. Having a single owner per project is a considerable time- and moneysaver. Having control over a budget, fully protected from the unforeseen, comes a very close second. The ability to get all the equipment on site at once frees the team to concentrate on the job at hand, while the on-site storage facility offers immediate convenience and peace of mind. Knowing that the cost of the consumables is limited to their use over a given month secures cash flow as well.

THE TRAINING YOU NEED AND THE SERVICE YOU DESERVE

Apart from equipment, ASACE offers a skilled technical engineering support team based in SA to provide hands-on training, led by its technical director with over 30 years’ hands-on experience in solutions for consistently achieving flat floors.

AN E-MAIL AWAY

Making contact with ASACE is about making the opportunity, not waiting for it.

It all starts here: sales@ allstatesafrica.co.za.

ASACE’S OFFERING

• One-stop, specialised concrete flooring consulting services.

MATERIAL ESCALATION: MINIMISING ADVERSITY

In recent engagements with our members, it has been established that certain baskets of material prices have escalated drastically and have affected the profitability of projects. Statistics SA has reported that the prices of materials used in the local construction sector have increased by 13,2% year-on-year in February 2022 from an annual increase of 14,5% in January 2022.

In the current economic climate, adverse material price impacts are expected and contractors are advised to take steps to mitigate against them. The various factors affecting material prices include rising energy costs, transportation costs, supply and demand, the

crude oil price, exchange rates, import cost s, inflation and raw material costs.

STEPS THAT COULD HELP

Value engineering: The goal of value engineering is to provide the highest construction value at the lowest cost. Encourage the project team to hold a value engineering workshop at the start of the project through a study of alternative design concepts, materials and construction methods without compromising the functional and value objectives of your client.

Prefabrication: Explore the option of prefabrication. The results may show a lower cost to transport some parts from a manufacturing

company than the outlay needed to manufacture from raw materials. An example is a prefabricated wall.

Material wastage: Material wastage contributes to the cost of sales on a project. Implement a lean construction model within the company or consider implementing a bill of materials to support the bill of quantities so that the correct quantities of material are purchased on a project.

Material alternatives: This is part of the value engineering chain. Explore material alternatives and remember to obtain approval from the client or the project manager

SOUTH AFRICAN BUILDER MARCH 2023 06 MBA NEWS
(Above): Alternative building materials can really keep costs down. Membership

when implementing this, especially if the material proposed to be replaced has been included in the project specifications.

BUYING STRATEGY

Implement a buying strategy at the start of a project by buying volatile commodities early and planning ahead. Dealing with the purchase of materials in advance, as opposed to the last minute, allows

the contractor time to shop around and buy bulk materials needed for the project. This provides leverage to negotiate further discounts. However, it is cash flowdependent and the propensity of scope change on any particular project should also be taken into consideration.

Consider negotiating a shared-risk contract strategy with regard to escalation – for example, a prime cost amount for unforeseen escalation which caps the client’s risk to the amount of that prime cost.

The contractor should also consider negotiating an advance payment on materials which could be used to purchase materials upfront, especially those which are susceptible to price volatility. Consider certain qualifications for quotes and/or contracts based on material price increases.

A proactive stance is required to deal with these aspects. Should you have any further queries in this regard, please contact MBA KZN.

Clay brick is proving to many sceptics in our built environment that sustainable construction is far from the rejection of the materials, methods and systems that have contributed so much to the world. Far from it: sustainability has underpinned research, studies, testing and innovation, revealing the many benefits of this ancient building material and driving its use in increasingly diverse and new ways.

Revitalised with a fresh perspective, clay brick is surprising both committed environmentalists and builders alike with new demand for its products coming from highly diverse markets. From off-grid living enthusiasts to commercial property developers, clay brick is hot property.

CLAY BRICK AT THE CUTTING EDGE

Johannesburg’s Sandton metropole concentrates the energy, wealth, power and diversity of Africa into a mighty, tight space. Forever transforming, its current developments are especially compelling, less for its new buildings than for the significance of what is happening to its older structures.

BlackBrick Sandton is a recently completed conversion which embodies the ethos of sustainability on a scale that integrates sustainability in just about every aspect of modern living. Its façade screams “visibility” – and clay brick was the sustainable solution, achieving far more than this aesthetic demand by bringing its unique mix of thermal properties, adaptive manufacturing

advantages and reliable, lowcarbon proximity of supply to this ambitious project. The manufacturer and supplier of the clay brick product is Federale Stene, a prominent member of the Clay Brick Association of Southern Africa.

FUTURE-FLEXIBLE, SUSTAINABLE STRUCTURES

Transforming old office blocks into a blend of comfortable living spaces, workspaces and community-fostering facilities is the leading trend for sustainable, mixed-use lifestyle developments. Designed on the “vertical village” concept, BlackBrick Sandton’s façade posed serious challenges in terms of both structural demands and those of a future-centric, sustainable vision.

As Mariana Lamont, executive director of the Clay Brick Association of Southern Africa, explains: “Sustainably designed buildings are energy- and resource-efficient and serve the long-term economic, social and environmental needs of

communities. Clay brick masonry demonstrates all these qualities during construction, throughout its long operational life.”

Not only are these bricks made from a highly durable natural material that offers an exceptional lifespan, but the clay from which it is made is also naturally insulating. “Clay bricks are thermal batteries, using energy from the sun to provide natural thermal efficiency, reducing the need for electricityguzzling air-conditioners, heaters and humidifiers,” adds Lamont.

BENEFITS OF BUILDING WITH CLAY BRICKS:

• Durable building material.

• Protection against major weather conditions.

• Aesthetically pleasing.

• Manage insulation well.

• Sustainable green building material.

• Low-maintenance.

• Made from natural raw materials.

• Energy-efficient.

• Low carbon footprint.

R-VALUES THAN JUST GOOD

“DR RAMOKGOPA WAS INVITED TO GIVE AN UPDATE ON THESE PROJECTS THREE YEARS LATER, WHEN HE INDICATED THAT THEY WERE STILL IN THE PLANNING PHASE.”

ADDRESS OF SELLO MOKAWANE, PRESIDENT OF MBA NORTH, ON THE STATE OF THE INDUSTRY

“Time flies, never to be recalled” wrote Virgil – and, true to his words, my first year as MBA North president has come and gone.

It followed 10 years of service on the MBA North Executive Committee and as an officer of the board, I am honoured to have been nominated.

I begin by thanking my colleague, past president Wayne Albertyn, for his sterling service. He stands out as the only president to lead the association through a worldwide

pandemic that resulted in the collapse of numerous established construction companies internationally and locally.

MAJOR CHALLENGES

The year under review is a clear indicator that the construction industry is not yet out of the woods. At the end of September 2022, Statistics SA published the growth rate for the sector as a -2,4% decline. This, coupled with delayed infrastructure projects and “business forums” disturbing sites

in some instances, as well as using violence and extortion, made for particularly challenging conditions in which to operate. President Cyril Ramaphosa again hosted one of his projects of investment summits at the Sandton Convention Centre in Johannesburg. Similarly, this year, various pledges for joint ventures between public and private sectors have been made, although their implementation has been very sluggish.

SOUTH AFRICAN BUILDER MARCH 2023 10 MBA NEWS
(Above): The 67 projects promised by government remain in planning phase.

PUBLIC-SECTOR PROJECTS

In 2020, the Minister of Public Works Patricia de Lille and newly-appointed government infrastructure development projects co-ordinator Dr Kgosientsho Ramokgopa launched an infrastructures Summit with the president in attendance. They presented 67 projects that were to be fast-tracked in partnership with the private sector.

Ramokgopa was invited to give an update on these projects three years later, when he indicated that they were still in the planning phase. Nevertheless, MBA North and MBSA remain positive and willing to help government break ground on these projects in the interests of the industry and our members.

As much as the association acknowledges and remains committed to alleviating the challenges facing main contractors, sub-contractors are also constrained. Therefore, in my remaining year as president, I will be extending the focus of the association to the challenges of sub-contractors, who are the implementers and deliverers of construction work on the ground, such as access to finance and guarantees.

TWO ICONS INSPIRING EMPOWERMENT AND TRANSFORMATION

Following the loss of two stalwarts in the industry – MBA North honorary member and past president Eunice Forbes and Dr Thandi Ndlovu, founding member and past president of SA Women in Construction (SAWIC) – the association will be prioritising the development, empowerment and inclusion of women, in line with

the broader BBBEE targets of the country. As an industry, we are still challenged by slow transformation when it comes to the inclusion and support of females.

In closing, I wish to thank the MBA North office-bearers, the staff under the leadership of executive director Mohau Mphomela and our loyal members, whom we are committed to continue serving in the coming year.

RAISING THE STANDARD: ROOFING AND WATERPROOFING

The launch of the BMI Coverland Roofing Academy has been welcomed by the Master Builders Association (MBA) North and the Professional Roof Repair & Waterproofing Association (PRAWA).

“We’ve been advocating the professionalisation of the roofing and waterproofing industry for some time. The launch of the BMI Coverland Roofing Academy is a very welcome development because it’s the first training provider where individuals can obtain an accredited National Certificate in Waterproofing,” says JJ Conradie, executive chairperson of the PRAWA. “We’re busy compiling the minimum standards in roofing and waterproofing, so this comes at just the right time.”

ESSENTIAL LINK IN CHAIN OF STANDARDS

Leonie Adams, training manager at the BMI Coverland Roofing Academy, says the importance of roofing cannot be overestimated. “If a roof collapses or leaks, it can cause enormous damage and even loss of life,” she says.

She adds that the academy offers a 12-month entry-level course, of which 70% is practical training, as well as courses for both skilled and semi-skilled workers within the construction industry who want to change careers. The National Certificate in Waterproofing is rated NQF Level 2 and is accredited by the Construction SETA.

SPOT THE DIFFERENCE

Adams points out that there is a distinction between approved waterproofing contractors, who have received training in a certain vendor’s products, and certified contractors, who have acquired the required level of all-round skills to be true roofing and waterproofing professionals. Roofing is highly specialised, making training to meet minimum standards essential to ensure that service providers are equipped to deliver the appropriate quality to customers.

The academy recognises prior learning, which can greatly reduce the time needed to obtain the certification.

The BMI Coverland Roofing Academy is situated in Roodepoort, with its headquarters at nearby JBC House.

TRAINING, SPONSORSHIPS AND CERTIFICATION

An exciting development is the launch of Pledge for a Learner to encourage players within the construction industry to sponsor the training of our people in roofing and waterproofing.

“SA’s population is set to reach 82 million by 2035, which means there’s a huge need for housing – and that includes good-quality roofing. This is a niche area of the industry that offers excellent career prospects, but it’s vital that new entrants have the requisite skills to ensure that the customers get the right quality and that the industry can grow sustainably,” says Adams.

“Certification is the cornerstone of any professional industry and soon only certified roofing and waterproofing contractors will be able to issue certificates of compliance,” adds Boitumelo Thipe at MBA North. “The Roofing Academy has a key role to play in helping this important component of our industry offer uniform high standards in line with the rest of the sector.”

RAISING THE RELEVANCE OF ENGINEERING PROFESSIONALS IN SA

2023 is a year of opportunity for the SA Institution of Civil Engineering (SAICE) to actively raise the relevance or value of the engineering professional, as perceived in the public sector, as well as its own relevance as a thought leader in the infrastructure environment and a fair arbiter of infrastructure evaluation. The SAICE will encourage the public sector to regard it as the employer of choice for engineering professionals. These are the sentiments of the institution’s new president, Steven Kaplan.

For his presidential theme for 2023, Kaplan duly explains that his focus will be on showcasing the value and relevance of civil engineering professional –engineers, technologists and technicians – in the built environment.

“I’ve taken up the gauntlet to re-establish the value and relevance of the engineering professional in the public and private sectors. It’s in this country’s best interests for infrastructure development to be led by the experts – the engineering professionals responsible for the foresight and know-how regarding building infrastructure that will leave a positive legacy for generations in the future,” he says.

CONSULTING ENGINEERS SA RESPONDS TO THE SONA

In response to the State of the Nation address, Chris Campbell, CEO of Consulting Engineers SA (CESA), states: “We’re pleased to see that our voice is being heard, with the imminent finalisation of the public procurement bill to address weaknesses identified by the state aimed at improving efficiency, value for money and transparency in our procurement system.”

Campbell says CESA is pleased with the continued focus by government on professionalising the public service, which will be staffed by skilled, committed, ethical people critical to an effective state and ending corruption, patronage and wastage.

He cautions that while the undeniable priority is dealing with

macro infrastructure issues such as energy and water security, “we must simultaneously accelerate the pace of fixing our micro infrastructure delivery systems”.

Campbell believes that there is still much work to be done and in order to achieve this, collaboration is key, as we are united by a common purpose.

PREVENTION OF HEAT-RELATED ILLNESSES

The hot and dry or humid weather conditions commonly found in KwaZulu-Natal can be dangerous for workers if they are not adequately prepared. Prolonged exposure to high temperatures increases the risk of developing heat-related illnesses such as sunburn, heat exhaustion, heat stroke or heat cramps. Symptoms can range from mild to severe and, in extreme cases, can result in death.

PREVENTION IS BETTER THAN CURE

A normal body temperature is 37°C. If it rises to 41°C, heat stress sets in. This is a life-threatening condition that requires prompt and competent treatment.

WHO IS SUSCEPTIBLE TO HEAT-RELATED ILLNESSES?

• New employees – it can take up to two months to acclimatise to the heat in a work environment.

• Older individuals, who tend to be less resilient and often

succumb to excessive heat exposure.

• Anybody exposed to excessive temperatures for an extended period.

• Persons under the influence of alcohol or experiencing the consequences of alcohol intake.

• Foreigners who are not used to the natural climate of the area.

• Anybody who is ill, or whose body has been weakened due to illness.

RECOGNISING THE SYMPTOMS OF HEAT DISORDERS

• Extreme fatigue.

• General weariness.

• Muscle weakness.

• Muscle cramps.

• Nausea and vomiting.

• Mental disturbance, argumentativeness.

• Failure to sweat – this is extremely serious.

TREATING THE SYMPTOMS OF HEAT DISORDERS

If a person displays one or more of the above symptoms, do the following:

• Move the individual to a cool, well-ventilated area.

• Attempt to reduce the core temperature of the body to below 39°C.

• Spray the victim with tepid water to simulate sweat.

• Increase air movement around the body.

• If the person’s temperature does not decrease to below 39°C within five or six minutes, seek emergency medical assistance. Remember, heat stress kills.

The most effective way of reducing core temperature is NOT to immerse the person in ice-cold water, but rather as described above. Ice-cold water could lead to shock, as the body further increases its temperature to counter the cold water. The aim should be to simulate sweating.

MANAGE WISELY

Working in hot weather is manageable if one is prepared for it. Dress appropriately, drink sufficient water, rest in cool, shaded areas and recognise signs of overheating.

MARCH 2023 SOUTH AFRICAN BUILDER 17 INDUSTRY NEWS
(Above): Preparation, sensitivity and caution can ensure continued operations with little or no risk.

As part of its three-decade sustainability journey, AfriSam has over the years championed the use of extenders to reduce clinker content in its composite cements. Through its Vanderbijlpark, Gauteng-based slagment operation, the company has pioneered the use of blast furnace slag, a by-product of the steel industry, to promote more sustainable products in the market.

The use of extenders in AfriSam’s composite cements has resulted in a substantial reduction in its clinker factor without compromising the quality of products. Blast furnace slag remains central to its efforts in this regard.

CLINKER SUBSTITUTION

Since 2008, the South African cement industry has seen a yearon-year reduction in emissions per ton of cement, largely driven by the increased focus on clinker substitution. According to the Association of Cementitious

CEMENT SUBSTITUTION – COMPOSITE REVOLUTION

Material Producers, clinker substitution rose from 12% in 1990 to 23% in 2000 and a substantial 41% in 2009. The industry is pressing for a 60% rise by 2030.

Over the years, AfriSam has accelerated its efforts to substitute clinker through the development of composite (extended) cements. In 2000, it launched Project Green

Cement to increase the use of extenders to promote more sustainable products. The use of extenders, says Hannes Meyer, cementitious executive at AfriSam, has resulted in a substantial 20% reduction in the company’s clinker factor since 1990.

COMPOSITE OPTIONS

Composite cements, he explains, contain not only clinker, but other cementitious materials such as pulverised fly-ash from coalfired power stations and ground granulated blast-furnace slag (GGBS) from steel-making plants.

GGBS has been used in the manufacture of cements since the second half of the 19th century.

SOUTH AFRICAN BUILDER MARCH 2023 18 INDUSTRY NEWS
(Right): The company was the world’s first construction material supplier to carbon-footprint all its production operations, including cement, aggregate and ready-mix. (Below): AfriSam has reduced its carbon emissions by 33% since 1990.

Back then, the practice was to intergrind the blast furnace slag with clinker. However, in the 1950s, AfriSam’s slagment operation pioneered the use of separately ground slag for the construction industry.

The use of this product has grown steadily in SA, with AfriSam among the front-runners. The company’s slagment operation plays a crucial role in the production of its composite cements. Established in 1955, the plant was previously owned by three companies, until AfriSam acquired 100% shares in it in 2004. The raw material is sourced from steel producer ArcelorMittal SA, which is strategically located a few metres away from the plant.

THE BRIGHTEST AND THE BEST Blast furnace slag has good cementitious properties, providing enhanced strength and durability. By evolving its chemical and mechanical activation

methods, AfriSam has achieved a more reactive product, allowing the company to progressively replace more and more clinker while retaining high cementitious quality and strength performance.

“Re-using waste products from other industries reduces the amount of limestone that we have to mine and clinker that we have to produce, thus reducing carbon emissions

from those processes, as well as minimising waste to landfill,” says Meyer. “We’re therefore constantly searching for new extenders and additives to further reduce our carbon footprint and our impact on the environment at large. The end result is less clinker produced per ton of each final product, resulting in less CO2 generated from our operations.”

ROCLA AND TECHNICRETE SUPPLY CONCRETE PRODUCTS

FOR ROAD UPGRADES

The constant increase in the development of lifestyle estates and commercial office parks in areas which were previously open spaces puts increased pressure on existing infrastructure, creating challenging situations that require economically viable engineered solutions. Hazeldean Road, part of the Riverwalk Project near Pretoria East, is currently undergoing upgrades not only to reduce traffic congestion between the Blyde and Silver Lakes residential estates, but to improve stormwater and road infrastructure. Rocla and Technicrete were contracted to supply the supporting stormwater solutions.

“Rocla supplied 1 564 interlocking joint [IJ] pipes of varying sizes, while sister company Technicrete delivered nearly 7km of Figure 7 [semi-mountable] and Figure 10 kerbs,” says Lourens Swanepoel, site agent with Kwa Mhlanga Construction. Technicrete also supplied 3 500m² of Amorflex 180, a flexible heavy paver which is specifically suited for stormwater and drainage applications that were stipulated as a requirement for this project by the engineers.

Rocla’s IJ pipe is for use in stormwater applications. The male/ female-type joint is formed inside the wall of the pipe, which ensures no widening of it. This means that the outside dimensions of the pipe remain constant. The joint itself is used for centering the pipe during laying operations, making the process easier.

For the project, 730 x 450mm IJ pipes, 17 x 675mm IJ pipes, 280 x 750mm IJ pipes, 30 x 825mm IJ pipes, 122 x 900mm IJ pipes, 55 x 1 050mm IJ pipes and 330 x 1 350mm IJ pipes were supplied.

Armorflex 180, an internationally licensed product of Technicrete, is an articulating concrete block system specifically designed for stormwater management and ideally suited to the lining of trapezoidal channels. The Armorflex 180 blocks provide a loose, but sophisticated interlocking design, allowing the surface to remain flexible to movement without the cracking and spalling issues that occur with in-situ cast concrete when exposed to regular stormwater or flooding incidents causing layerwork subsidence.

Figure 7 kerbs from Technicrete are versatile precast ones generally used for edge restraint in the construction of roads, kerbs, gutter systems and rumble strips. Figure 10 kerbs are a light- to medium-

duty bull-nosed edge restraint normally used for pathways which could be accessed by vehicles in an emergency situation or those needing to be guided to remain on the paved paths.

Technicrete precast concrete product solutions have been installed in numerous projects around South Africa for over 50 years and offer a wide range of kerbing to meet any developmental requirement.

Swanepoel says he was impressed with the quality of the products from both Rocla and Technicrete. “It’s on that, after all, that their reputation rests,” he says.

IN SA’S ENERGY LANDSCAPE NEW SAWEA BOARD TO LEAD WIND SECTOR’S ROLE

The SA Wind Energy Association (SAWEA) has announced its new board of governance, following its 11th annual general meeting held in Cape Town on 27 January 2023. As the country accelerates its energy transition and pushes for energy security, those who hold positions on this board will be charged with steering and advocating for wind.

Dhesen Moodley has been elected as the new chairperson of SAWEA and previously served on the board for over a year. Having built a career in the finance and energy sector, he has a deep history in developing, financing and managing independent power projects with exposure to solar PV, CSP, coal, gas and mini-hydro assets. He currently leads a team of over 80 South Africans, managing a portfolio of six solar and two wind assets in which Globeleq is a majority shareholder.

“Although SAWEA has successfully advocated more wind in the country’s energy plan, we’re facing serious challenges. We need to work with government, key stakeholders and business to find solutions to the challenges, primarily hinged on grid access, so that new electricity can be injected into the network as soon as possible,” says Moodley.

“Wind technology is uniquely positioned to support energy security, as it provides cost-competitive generation during the evening peak demand hours and complements the growing fleet of utility, commercial and residential solar PV. It’s time to roll up our sleeves and chip away at loadshedding as a national initiative. The next few years won’t be easy.”

Three new board members, simultaneously voted in, include Nontokozo Nkosi, Titania StefanusZincke and Jose Rodrigues. They and Moodley join existing members Mercia Grimbeek and Mark Tanton.

Board members hold strategic leadership roles in their respective organisations and therefore bring immense experience to the wind energy sector, ensuring that the organisation is well positioned to provide leadership to the broader industry. The board represents a blend of developers, IPPs and OEMs, encompassing the critical role-players in the wind energy value chain.

SAWEA operates as a common-law, voluntary notfor-profit association that represents the SA wind industry. The board is primarily concerned with issues of governance and strategy.

GET YOUR ENERGY PERFORMANCE CERTIFICATES IN ORDER…

The Department of Mineral Resources and Energy (DMRE) extended the 7 December 2022 deadline for the mandatory display and submission of energy performance certificates (EPCs) for buildings by three years, with only a fraction of non-residential buildings having already complied with the requirement. This gave building-owners some reprieve.

“The extension was welcomed by many industry bodies,” says Kagiso Mahlangu, director and head of real estate and conveyancing at corporate law firm CMS South Africa. “As the deadline drew closer, it became apparent that not many people had complied. There was a need to extend it because the intention wasn’t for a lot of building-owners to be fined or imprisoned for noncompliance.”

As the law is currently gazetted, those found not to be in compli -

ance face fines of up to R5 million or prison sentences of up to five years.

Mahlangu cautions that the extension should not, however, be seen as an opportunity for property-owners to keep kicking the can down the road. Instead, they should do everything in their power to get an EPC as soon as possible. Doing so not only puts them on the right side of the law when the deadline does come into play, but allows them to demonstrate to their tenants that they are making an active effort when it comes to promoting energy-efficiency. Remember, the built environment accounts for 40% of global emissions and 28% of energy consumption, making it a crucial sector for tackling the effects of climate change.

So what steps, exactly, should property-owners put in place when it comes to obtaining the certificates? And how can property practitioners help them?

UNDERSTANDING EPCS

Before exploring how nonresidential property-owners can ensure that they are properly certified, it is worth recapping what the certificates are designed to achieve and who is required to have them on display.

In essence, EPCs are designed to show anyone who looks at them how energy-efficient a building is in a way that is convenient and easy to understand. Anyone who has bought a new large appliance over the past few years will be familiar with the concept. The certification requirement applies to offices, entertainment facilities, educational institution buildings and places of public assembly such as indoor sporting facilities and community centres. Buildings also have to be more than two years old and have a net floor area

(Above): The work of upgrading existing buildings is still to be done, with most failing to have met the November 2022 deadline.
NOW

of over 1 000m² for government buildings and 2 000m² for privately owned buildings in order to be impacted by the certification requirement.

Administered by the SA National Energy Development Institute (Sanedi) on behalf of the department, EPCs grade buildings on how much energy they use per square metre. The gradings are on a scale from A-G, with A being the most efficient and G the least.

In order to obtain certification and grading, building-owners must gather information including annual electricity consumption, the net floor area, information on any areas to be excluded and vacancy rates. From there, the onus is on the owner to contract a SA National Accreditation System (SANAS)-accredited inspection body (IB) to audit the information. The IB will, in turn, submit the energy performance value to Sanedi, which inputs it into the National Building Energy Performance Register. From there, a unique number is generated for the EPC and sent back to the IB, which issues the EPC so that it can be displayed in the building.

GET THINGS IN ORDER NOW

As Mahlangu points out, part of the problem with compliance is the fact that the certification process is not a quick one. She therefore urges building-owners to get started on certification as a matter of urgency.

“It’s not a case of simply filling in a form and you’re done,” she says. “There’s information

that needs to be collated, collected and verified before the certificate’s actually issued.”

According to the CMS law firm director, even the fact that the extension was necessary shows that it is better to comply sooner rather than later.

“If the original deadline had stuck, many people would be facing severe penalties in the shape of fines or imprisonment,” she says.

but regard it as a chance to get in line with global building ownership and management standards.

“At the end of the day, these regulations are about ensuring that SA aligns with global practices,” she says. “For example, I was recently in France, where EPC grades are displayed on all property listings.”

While EPCs do not currently have to be included as a condition of sale or rental for building-owners, those with higher ratings will, inevitably, become more attractive, especially as concern for the planet becomes more universal.

“I think the whole intention for EPCs is great for the country and great for the environment,” says Mahlangu. “It will conscientise many owners about how they’re using their building energy and how best to make their buildings more efficient. We’ve got an energy crisis as a country and planet and there needs to be a shift sooner, rather than later.”

For this reason, she hopes that there will not be a further extension to the EPC deadline.

“We need to start ensuring that people are aware of the fact that the way we utilise energy in our buildings has a direct effect on our planet,” says Mahlangu.

GETTING IN LINE WITH GLOBAL STANDARDS

“When one considers greenhouse gas emissions for SA, buildings represent the major share of those emissions, making them lowhanging fruit when it comes to ensuring that the country meets its emission targets.”

WORLD-FIRST COLLABORATION EMPOWERS CONSTRUCTION PROJECT MANAGEMENT IN SA

In a world-first collaboration, the SA Council for the Project & Construction Management Professions (SACPCMP) and the Project Management Institute (PMI) have come together to offer construction-specific learning and development to those registered under the SACPCMP. The partnership will boost the international currency of South African construction professionals.

“This is the first time ever that a regulator has collaborated with the PMI to create an opportunity for its industry professionals to improve the global currency of their registration,” says SACPCMP registrar Butcher Matutle. “The collaboration between the two entities will open the door for

international recognition for SACPCMP registered persons, who’ll benefit from undertaking learning and development that’s not only constructionfocused, but also recognised internationally.”

The PMI has launched a suite of online courses and microcredentials to address the unique challenges faced by construction professionals. The courses aim to improve project management skills in the construction industry and lead to Construction Professional in Built Environment Projects (PMI-CP) certification.

WASTEFUL EXPENDITURE IN THE CONSTRUCTION SECTOR

“Annually, wasteful expenditure in the construction sector

globally amounts to $1,6 trillion,” says George Asamani, the PMI’s Sub-Saharan African MD. “These courses are designed to help construction professionals improve margins in the industry often plagued by cost overruns and project delays and are the PMI’s first industryspecific solution designed for construction professionals.”

The collaboration between the two entities supports the mandate of the SACPCMP, which seeks to support learning and continuing professional development in the construction sector. It is also a path for those registered under the council to engage in globally recognised learning that could enhance their international appeal as professionals.

GLOBAL RECOGNITION FOR SA PROFESSIONALS

“We’re excited by the multilevelled benefits offered through this collaboration,” says Matutle. “SACPCMP professionals will be able to access this courseware at a preferential rate and continue to develop themselves in line with international best practices, while maintaining their registration requirements.”

He adds that SACPCMP applicants who need to develop their knowledge base to meet professional registration requirements will have the opportunity to do so through the collaboration. “Applicants can now select specific courses or modules that address pinpoint areas they may need to develop. The longterm benefit of this will not only be a fully competent construction industry, but the development of additional career pathways for the built environment.”

PMI-CP comprises seven courses, three of which offer microcredentials. Each course explores a specific area of construction project management. The certification was developed in collaboration with construction industry leaders and consultations with project managers who face the twin challenges of balancing technology and talent.

ADAPT TO THRIVE –TRANSFORMING SA CONSTRUCTION

“As with many sectors, the construction industry is seeing change. Adapting to change is key and demands different skills sets.

to complete projects successfully. The PMI believes that people and their skills are critical to improving project performance,” says Asamani. “This partnership between the SACPCMP and the PMI, with each partner striving for excellence in their respective specialties, will create a solid platform for the construction industry to deliver better outcomes.”

SA is no stranger to the difficulties facing the construction industry. However, to meet the demand for R812,5 billion worth of planned infrastructure projects over the next three years, proactive steps must be taken.

“If the SA construction industry is to leverage the massive infrastructure opportunity, it must accelerate the upskilling of construction professionals. The

PMI is positioned to equip the sector with the competencies needed and, through the collaboration with the SACPCMP, we’ve built a platform to ensure that the industry’s strengthened by professionals who can adequately address the complex nature presented by the construction sector,” says Matutle.

The agreement was officially signed by Asamani, the SACPCMP’s president Isaac Nkosi and Matutle in Gauteng on 14 November 2022. Tunde OjoAromokudu, president of the PMI SA Chapter, was also present at the signing. The agreement will facilitate access for SACPCMP registered professionals and applicants to the PMI’s CP courses and certification at a reduced rate.

DIGITISING FOR AN OPTIMISED,

ENVIRONMENTALLY FRIENDLY GRID

Schneider Electric

The ripple effect of South Africa’s load-shedding is well publicised, impacting the entire user life-cycle, from large conglomerates to our own homes. Sadly, loadshedding has the potential to impact not only the productivity and income of consumers, but also the very system that provides us with power.

Equipment kept in sub-stations and distribution centres, new or old, is not designed to withstand an onslaught of surges, continued

interruptions and on/off switching multiple times a day.

One example is medium voltage (MV) switchgear that has been designed, in optimal circumstances, to last up to 40 years. However, as mentioned, no equipment can handle the extraordinary circumstances that come with load-shedding, which means that switchgear and other equipment simply stops working well before its projected end of life.

In the case of gas-insulated switchgear, the way SF6 is collected and recycled at its end of life is a major priority. Furthermore, with pure air-insulated switchgear now becoming available, there is a compelling case for replacing faulty equipment with SF6-free options.

SF6-free MV switchgear is a viable choice not only for

the environment, but also for operational safety. Additionally, it offers ease of maintenance, end-of-life treatment, functionality and performance, as well as environmental compliance.

Pure air switchgear is natively connectable, which means that new equipment can be added with minimum disruption. SF6free switchgear is also designed in such a way that it does not require operator retraining, thus mitigating downtime. And, importantly, if there is a gas leak, the pure air will simply escape into the atmosphere, causing no environmental impact.

MAINTAINING A STABLE GRID

One of the main responsibilities of utilities is to maintain voltage limits to ensure safe, stable and optimised usage. Voltage control is traditionally performed by transformers using on-load tap changers and capacitor banks that inject reactive power into the grid at the MV sub-station level.

The grid operator then fixes a set point and prepares scenarios and ranges based on seasonal load curves, as an example.

However, as we add more distributed energy resources to the grid, effective energy mix management becomes critical. It is paramount – as renewable resources are added – that this is managed intelligently, keeping a close eye on, for example, loads during peak and off-peak times. This will enable management of a stable grid comprised of fossil and renewable energy resources.

Several new digital solutions can be deployed to address this challenge:

Next-generation remote terminal units allow users to remotely control the sub-station and to accurately track operating parameters to ensure stable operations during load-shedding, for example.

New smart sensors can easily be installed on new and existing switchgear and can be connected to the cloud or on-premise

systems, as required. They allow for predictive maintenance and endof-life management, which are key in reducing long-term costs.

Digital twin environments allow for virtual modelling of networks, providing insights into equipment performance within the set parameters.

SF6-FREE AND DIGITAL TECHNOLOGIES –A POWERFUL FORCE

Modern, digital technology allows us to untangle the complexity of modern electricity networks and the increasing levels of renewables and DERs coming into the fold.

Coupled with connected SF6-free switchgear, we are one step closer to finding a sustainable solution to the impact of greenhouse gas emissions on the environment.

RE-USE VS RENOVATION – NEW PERSPECTIVES

Land is a limited resource, but demand for construction keeps rising. That situation, paired with the push for greater sustainability, presents a challenge – but the answer may lie in buildings that already exist. With adaptive re-use, construction firms can create new spaces without building an entirely new structure.

WHAT IS ADAPTIVE RE-USE?

Adaptive re-use, also called architectural re-use or building reuse, is the practice of repurposing an old building for a new use. Unlike conventional renovation, it does not refresh a property so it can keep serving its current

or old role. Instead, it gives buildings a different purpose, essentially creating a new property without complete demolition or construction from scratch

The US government owns an estimated 45 000 under-utilised buildings and many more commercial properties sit abandoned, taking up city lots without contributing to the economy. This vast availability of unused, ageing structures provides ample opportunity to minimise waste and urban sprawl while simultaneously meeting a city’s current infrastructure needs.

Old churches can become restaurants, abandoned industrial complexes can become low-

income housing and historic government buildings can become museums. By re-imagining these structures, construction firms can address multiple problems facing America’s infrastructure in a single project.

BENEFITS OF ADAPTIVE RE-USE

The most direct benefit of adaptive re-use for construction companies is that it is costeffective. It often takes less time and money to renovate an existing space than to design and construct a new one of the same size. That is particularly helpful for firms facing significant backlogs after recent demand spikes.

SOUTH AFRICAN BUILDER MARCH 2023 30 FEATURE
(Above): The original Detroit Fire Department.

This approach to architecture is also far more environmentally friendly than building from scratch. Because these projects take less time, fossil fuel-powered heavy equipment runs less frequently and emits less greenhouse gas. With much of the structure already existing, firms also add minimal embodied carbon to the property and avoiding demolition creates less waste.

Re-using existing architecture also reduces urban sprawl, as it provides new space for businesses without taking up new lots. Bring -

ing historic buildings back to life can also preserve the community’s heritage and improve an area’s aesthetics, improving spirits and the quality of life in the area.

TYPES OF ADAPTIVE RE-USE

There are many different types of adaptive re-use, too. This variety of approaches further expands the possibilities of what construction firms can do with old buildings. Here are five of the most exciting and beneficial of these strategies:

1. Renovation

The most familiar type of adaptive re-use for most professionals is renovation. In this approach, construction teams repair, rebuild or refurnish much of the inside of a building, but leave the exterior largely unchanged.

It is important to note that renovation in this context differs from the conventional sense of the word. Instead of refurbishing a property to make it better for the same purpose, it does so to give it a new use.

An excellent example is the Detroit Foundation Hotel, which repurposed the original headquarters for the Detroit Fire Department.

While the exterior still looks like an old fire station, the inside is almost entirely new, featuring more modern amenities and restructured layouts to accommodate the new business. Not all renovation projects are so dramatic, but adaptive renovations are typically more involved than simple refurbishment.

2. Historic preservation

Historic preservation is a similar, but distinct approach to adaptive re-use. In these projects, the primary goal is to preserve or restore the building’s history. Like renovation, it often deals more with the interior than the exterior, but it keeps much of the original interior’s aesthetic and integrity.

Changes in this type of re-use often include upgrades to meet current building codes. As green building becomes an increasingly important trend, some projects also implement more energyefficient infrastructure to help historic properties reduce their carbon footprints.

This approach is ideal for museums, as the building itself can become an art or history installation. Even though the property serves a different purpose now, it holds onto its roots to preserve its community significance.

3. Façadism

If an old building is in particularly poor repair or has little historical significance, firms may opt for façadism. This type of adaptive

(Above): Repurposed and better than new, the magnificent façade of the Detroit Foundation Hotel.
“BRINGING HISTORIC BUILDINGS BACK TO LIFE CAN ALSO PRESERVE THE COMMUNITY’S HERITAGE AND IMPROVE AN AREA’S AESTHETICS, IMPROVING SPIRITS AND THE QUALITY OF LIFE IN THE AREA.”

FEATURE

re-use demolishes and rebuilds most of the structure, while keeping the street-facing side intact.

Keeping the façade while changing the rest of the building is a more involved, but practical approach to architectural re-use. Some teams may find it easier to integrate modern systems into a new structure than install them via minimally invasive fixes.

4. Integration

Most approaches to re-use focus on internal changes to historic buildings while preserving their exterior. Integration takes a more dramatic direction by leaving the entire original structure in place while building new infrastructure around it.

The Union of Romanian Architects Building in Bucharest is a great example. When the union sought to convert the old secret police headquarters into its own office, it could not demolish it because of its protected historical status. Instead of changing the structure, it added a modern office space on top of it, giving it new life while preserving the entire original building.

5. Infrastructure adaptive re-use

Adaptive re-use can revive structures apart from buildings, too. Infrastructure re-use takes outdated or crumbling infrastructure like highways, railroads or industrial plants and turns it into new public works like parks.

The High Line in New York City is one of the most famous examples. The site used to be an elevated railway, but fell into disrepair after rising truck usage

rendered the rail unnecessary. In the early 2000s, architects turned it into a park with walking tracks, viewing balconies and an openair market, letting the structure serve the community again.

With so much ageing infrastructure in the USA, this type of re-use is an increasingly attractive option. It also provides needed green spaces or safe community gathering points without clearing existing lots.

MAKE THE MOST OF A BUILDING BY RE-USING OLD ARCHITECTURE

Old buildings do not have to fall into under-use and new ones do not need to involve extensive demolition or urban sprawl. Adaptive re-use lets construction firms join the past and present to preserve architectural history, while meeting the future’s needs. Leaning into this trend will also help the sector become more cost-effective and sustainable.

THE STATE OF OUR NATION

In many increasing ways, the momentum of nation-building and economic growth takes place despite our politics. On 9 February, President Cyril Ramaphosa chose a deeply impersonal approach in delivering his State of the Nation Address (SONA ), as if to distance himself from the very challenges politics has created.

We know that there are no shortcuts, especially at foundation level. So as we assess what we are being told, it is vital that we channel our inevitable frustration into a viable path forward, bearing in mind that working together always yields infinitely more value than retreating into a defensive stance.

THE GOOD AND THE BAD

“What we’ve achieved as a nation over the past year, despite our challenges, reminds us that the promise of South Africa is alive,” began Ramaphosa. “Today our economy’s larger than it was before the pandemic.” These things are true – though not thanks to government, but in spite of it. Think of all those performing artists whose designated relief funds never reached their bank accounts. Think of all the privatesector high-risk investments that created those jobs. These accomplishments are decidedly ours, not the state’s.

“Our country has, for many months, endured a debilitating electricity shortage that’s caused immense damage to our economy,” lamented Ramaphosa.

The point is not to allocate blame; that is well enough understood. The point is to take very seriously what we – South African citizens, organisations and companies –continuously achieve, despite the many odds.

WHAT IS THE PLAN?

“We’re not presenting new plans, nor are we outlining here the full programme of government. Rather, we’re concentrating on those issues that concern South Africans the most: load-shedding, unemployment, poverty and the rising cost of living, as well as crime and corruption. Our most immediate priority is to restore energy security,” said Ramaphosa.

While it was good to hear these admissions, we must remain cautious of their function. Graft is so entrenched that it can seem pointless to even address the power crisis without first addressing the crisis of those in power.

The official plan outlined five key interventions:

1. Fix Eskom’s coal-fired power stations and improve the availability of existing supply.

2. Enable and accelerate private investment in generation capacity.

3. Accelerate procurement of new capacity from renewables, gas and battery storage.

4. Unleash businesses and households to invest in rooftop solar.

5. Fundamentally transform the electricity sector to achieve long-term energy security.

optimising the skills, technologies, financial instruments and market opportunities to expedite the utilisation of 21st-century technology. The 2023 SONA ignored the very interventions spelt out in our much-vaunted Just Transition Plan presented last year by then Eskom CEO André de Ruyter.

WE DO HAVE POWER

It is a coincidence that our urgent need to tackle carbon emissions dovetails so exquisitely with the socalled Fourth Industrial Revolution. We are no longer constrained by yesterday’s electricity supply chain. The technologies to create, optimise, distribute and manage a variety of grid-types, while feeding into a national grid, need the involvement of all primary sectors, including the financial one. Supporting the co-ordination of builders, bankers, designers and engineers is surely the best way to open the doors of opportunity for every South African. Which is not to say that none of this has been done already – it is merely to say that the context has changed radically over the past six months.

A MIXED RESPONSE

Reaction to the 2023 SONA from the construction sector has been mixed. In its statement, the SA Institution of Civil Engineering remains concerned about public-sector accountability. “We understand that there is no easy fix for government to improve the country’s economy and infrastructure status. We need to increase the investment in infrastructure from 13,7% of GDP in 2020 to at least 30% by 2030. We need to reduce habitual

underspending of infrastructure budgets by those public-service providers who are not held accountable, [resulting in] service delivery failures, poor governance, weak institutional capacity and instability,” it stated.

The Engineering Council of SA has offered to give as much assistance as required by deploying engineers to work with the management teams at power stations. “We have deep skills and expertise right here in SA – we just need to use them,” it noted.

Action Plan and look to the new minister to drive new-generation capacity onto the grid with haste,” stated Niveshen Govender, the association’s CEO.

Rein Snoeck Henkemans, a key player and expert in the residential and commercial solar sector, was hopeful that a pragmatic response in support of broadening access to ready solutions was on the cards. “The inescapable fact of the matter is that we need a working solution today, not in a couple of years from now. We’ve experienced close to 1 000 hours of load-shedding this year alone. If this trend continues, it’s impossible to know or even guess how much it will cost the average person or business-owner in the long term,” he said.

The SA Wind Energy Association was more upbeat in its response. “This isn’t the first time that our president has prioritised SA’s protracted energy shortfall in his SONA , resulting in significant reform which has helped to liberalise the energy sector. We once again hope that the changes proposed will accelerate the implementation of the Energy

However, Snoeck Henkemans did find one remark in the SONA heartening. “The address gave us at least one flickering ray of hope. The president promised to implement a tax incentive for solar, which may prove to be a sizable step in the right direction. Currently, we have no information on the conditions or extent of the incentive, but if this proves to be substantial enough, we could enter a golden age for solar which would significantly benefit business and households,” he said.

PARKS BOULEVARD BUILDING MARKS 7-UP FOR CONCOR AT OXFORD PARKS

Concor continues to notch up successes at the Oxford Parks precinct, where it has been making rapid progress on 5 Parks Boulevard since July. This is the seventh building that the company will have built in this popular mixeduse development and it is being constructed to a high Green Star rating. Contributing to this rating will be environmentally responsible bulk concrete with a low CO2 footprint supplied by AfriSam.

LOW CARBON CEMENT AT HEART OF GREEN CERTIFICATION

After beginning construction this July, Concor is well on track to topping out another elegant office block in the Oxford Parks precinct, using environmentally responsible ready-mix with a low CO2 footprint from AfriSam.

The modern 5 Parks Boulevard building is one of Intraprop’s latest projects in this fast-growing mixeduse development in Rosebank, Johannesburg. Such has been Concor’s success that the building is its seventh contract there.

“Like our previous Oxford Parks projects, this building is designed to achieve a high Green Star rating by the Green Buildings Council SA,” says Martin Muller, contract manager at Concor.

SCOPE OF WORK

The office block will comprise four basement levels and five office levels, offering about 7 300m² of gross leasable area. The design includes a triple-volume atrium in the reception area to make the most of natural light and reduce energy. This feature extends from the ground floor through to the second floor. Further utilising the natural light is a double-volume area on the third and fourth floors.

“The structure’s based on conventional reinforced concrete slabs from the basements to the roof, with a lift core to accommodate three lifts down to the lowest basement,” says Muller. “As the bulk concrete supplier, AfriSam’s providing 150-250m3 of ready-mix concrete for each slab.”

He highlights that, as a Green Star-rated building, the concrete mix designs are required to reduce the overall CO2 footprint of the structure. This has been achieved by using more fly-ash in the mixes, thereby reducing cement levels by 30%. He notes that the quality and consistency of AfriSam’s mixes have allowed Concor to reduce the cycle time of each slab pour from the normal 11 days to nine or 10 days.

THE ART OF FAST-TRACKING

“On a fast-track project like this one, the mixes enable us to speed up our cycle times, as we can de-stress the slab and recycle formwork to the next level more quickly,” he explains.

Quality assurance on the concrete is done both by AfriSam and Concor. After every concrete slab pour, concrete cubes are cast. They are then crushed to test their strength after seven days, 14 days and 28 days. While 25MPa strength concrete is used for the slabs, higher strengths from 35-60MPa are used for the columns and verticals.

The anchor tenant plans to occupy the third and fourth levels of 5 Parks Boulevard.

TWO HILLBROW ICONS

Augy Da Costa’s journey as a property developer spans 15 years and includes successfully refurbishing two buildings in one of the most densely crowded suburbs in Gauteng – Hillbrow. Originally a mechanical engineer, with the aid of TUHF, Da Costa found success by refurbishing previously run-down spaces into vibrant hubs for retail and residential tenants.

HOLLYWOOD HEIGHTS

The transformation of the first of his ventures, Hollywood Heights on the corner of Pretoria and Claim Streets, began when he purchased the ramshackle building in 2005. The first addition was a bakery spanning 850m², which performed well. From 2009-2012,

Hollywood Heights received a new lease on life when Da Costa, with a loan from TUHF, refurbished the building, converting its existing office space into 196 residential apartments.

Today, there are 14 studio apartments, 56 bachelor apartments, 84 one-bedroomed and 42 two-bedroomed apartments. Each unit is affordable, with rentals ranging from R2 800-R5 800. Hollywood Heights also caters to a variety of retail tenants, including

McDonald’s, African Bank, Capitec, Nedbank, Western Union/Travelex, Hollywood Bets, a barber shop, Cyber Café and a coin-operated laundromat.

The building has a unique feature that lends itself further to constructing a new family – a school of its own. ‘’The school has eight classrooms and caters for Grades 00-R, with its own secure playground which the children of tenants can use under supervision,” he explains.

CUMBERLAND COURT

Five years later, Da Costa followed Hollywood Heights with another

building which he and TUHF revitalised – Cumberland Court, on the corner of Pretoria and Klein Streets. This residential complex underwent a significant refurbishment, involving some apartments being converted into two bedrooms and the construction of an eight-storey tower that could accommodate eight additional one-bedroomed apartments. Cumberland Court now contains 54 one-bedroomed apartments and six two-bedroomed apartments, along with one bachelor’s apartment. Rentals cost R4 750 for a one-bedroomed unit and R5 900 for a two-bedroomed one.

As refurbishing the buildings was capital-intensive, Da Costa credits his partnership with TUHF for making it possible. “The ‘Big Five’ banks’ loan period was eight years, whereas TUHF offered a 15-year loan, which certainly helped with my cash flow,” he explains.

SAFETY, SECURITY AND AMENITIES

Contributing to the success of both properties is their close proximity to public transport, the city centre and accessible wifi for a flat monthly fee. Residents can also bring their own DStv decoders and use the existing infrastructure. Both buildings are served by comprehensive security, with Hollywood Heights watched by 10 security guards

and 160 surveillance cameras and Cumberland Court served by three security guards and 50 cameras. Additionally, all units have intercoms and the buildings feature biometric access.

Both Hollywood Heights and Cumberland Court cater to a wide range of tenants, from students and single, young professionals to new families. Many of the tenants work in the food and restaurant industry. Easy access to restaurants and a Super Spar also makes it an attractive place for families and single people to call home.

CHALLENGES AND OPPORTUNITIES

As with all projects, there were challenges to overcome. “Up until April of 2020, when the pandemic began, I hadn’t known the meaning of the word ‘vacant’. I’d never had any vacancy whatsoever for all those years,” says Da Costa.

While Covid-19 changed that for a while, today both buildings have largely recovered, with Hollywood Heights and Cumberland Court currently having a 96% and 98% occupancy rate respectively. This is a notable achievement, as one of the major challenges

property-owners have faced –which was amplified during the peak of the coronavirus – has been the devastating impact of high unemployment and its knock-on effect on occupancy rates, as people struggle to make ends meet. For Da Costa, the difficult economy has caused him to put his plans for his next developments on hold until the economy improves.

Those next plans (again with the aid of TUHF) are to continue refurbishing properties in Hillbrow – a market he now understands very well.

WHY SUSTAINABLE BUILDING MATTERS

In the current economic climate, many consumers are becoming more risk-averse and careful about where they spend their money. Trends show that sustainable brands are preferred over the rest.

SUSTAINABILITY GOES BEYOND GREEN

Contrary to popular belief, a sustainable brand is one that has successfully integrated environmental, economic and social issues. It is not just about being green. In fact, most companies that people think of as being sustainable only fufil onethird of the requirements. Being a truly sustainable brand, such as Swartland, involves manufacturing sustainable products in a sustainable way, as well as integrating sustainable economic and social pillars into the business operations.

SUSTAINABLE MANUFACTURING

Sustainability requires thinking in terms of the cradle-to-grave theory, rather than simply focusing on the end product. It is also important to consider whether

the product is manufactured from sustainable materials in an ecologically beneficial manner. For example, Swartland’s windows are SANS 613-certified and compliant. They have all been tested for deflection, structural strength, water-resistance, air-tightness, operating forces and the best possible energy-efficiency. More than that, they are made from sustainable materials, including timber sourced from sustainable FSC- and FLEGT-certified mills, or aluminium that is 100% recyclable.

Swartland also manufactures its windows in a sustainable manner – the best wood cuts are used to create the finest windows and doors. Other grade cuts are used for wood laminate products, while the timber which is not used in production is utilised as fuel for the boilers that kiln-dry it. Any leftover shavings or sawdust are sold on to local farmers for chicken bedding. ”Virtually nothing is wasted,” says Cobus Lourens, the company’s national sales manager: Ready 2 Fit.

Swartland’s products are also manufactured to last a long time, thus minimising their overall carbon footprint. “Whether it’s windows, doors, timber mouldings or insulation, all our offerings provide best-in-class quality and longevity,” he adds.

ETHICAL BUSINESS PRACTICES AND PRO-SOCIAL BEHAVIOURS

Sustainability is also about ethical practices and dealings. In Swartland’s many years of operating in an environmentally responsible and sustainable way, it has found that cutting costs in the present becomes less important than the real cost in the future to both communities and the environment, says Lourens.

A SIGNIFICANT STEP IN THE RIGHT DIRECTION

According to the Electrical Installation Regulations (EIR), as contained in the OHS Act, only registered electricians may do certain work: inspecting installations and issuing Certificates of Compliance (CoCs), such as for purposes of transfer when a property has been sold; undertaking maintenance and alterations; installing solar PV systems; erecting electric fence systems; issuing new CoCs when geysers are replaced and connecting generators to the main supply, to name a few.

In the wrong hands, electricity is dangerous, particularly if the work is done on the infrastructure – the power network – which can impact other units in the estate. It is simple: obey the law and only use an electrical contractor who can prove that they are registered –ideally an ECA member, who also has the back-up of an association which has been around for nearly 75 years. Duly qualified and registered ECA members are listed in the “Find a member” section on the ECA’s website.

COVER

While reputable electrical contractors have public liability insurance cover as a matter of course, it is unlikely that unregistered electricians have that kind of protection. Work done by ECA members in good standing is also covered by a

Workmanship Guarantee to the value of R20 000.

SOLAR PV

There is more to compliance than just making sure that the electrician is registered; owners, managers and bodies corporate must also ascertain whether an electrician is qualified to undertake the work they have been employed to do. Some work, such as solar PV installations, may only be done by an installation electrician or a master installation electrician, who will also issue a CoC for the PV system.

When any alterations have been done to an electrical installation, a supplementary CoC for the alteration must be issued.

GEYSERS

When a hot water cylinder (geyser) is replaced – usually as the result of an insurance claim – it must be remembered that this is an alteration to the installation and it is incumbent on the user to obtain a supplementary CoC for the new geyser.

GENERATORS

With load-shedding, many property- and business-owners are installing generators. In such cases, the electrical machinery regulations become applicable, along with the EIR. In short, when portable generators interface with fixed electrical installations, this must be done by a registered electrical contractor and a CoC issued. Failure to do so will invalidate any insurance claims in the event of fire or an accident.

FORCE FOR CHANGE

ELECTRIC FENCES

Only persons registered at DoEL as electric fence system installers may issue CoCs for electric fence systems. When there is maintenance work to be done on these fences, it is best to use an EFSI or an ECA member.

CERTIFICATES OF COMPLIANCE

Only registered electrical contractors may issue a CoC for a new installation or for an existing property for purposes of transfer.

The Association for Residential Communities, estate managers, trustees, bodies corporate, homeowners and sectional title-owners will soon be able to access the information they need to ensure compliance with the law and the safety of people, pets and property. A draft specification is being compiled by our technical and legal experts and, once complete and approved, it will also be shared on the ECA’s website in a downloadable format.

ARE CONTRACTORS READY FOR INCREASED SOLAR DEMAND?

Consumers are taking another serious look at solar energy after Eskom and the National Energy Regulator of SA recently announced an 18,65% tariff hike scheduled for April 2023, with another 12,47% increase on the horizon for 2024.

“A price increase of this magnitude amidst ongoing stage 6 loadshedding has considerably buckled consumers’ confidence in the

national energy provider. As grid deterioration outpaces repairs and consumers look cautiously to their shrinking wallets, the question becomes: can we afford not to make the change to solar?” asks Rein Snoeck Henkemans, MD of Alumo Energy.

NOT JUST FAILURE OF SUPPLY

The price of electricity has risen by 653% since the start of the energy crisis in 2007 – nearly three times greater than tariff hikes experienced in the two decades which preceded it. This comes even as increases in income per capita have stagnated in recent years.

Given these meteoric price hikes, consumers may soon find themselves choosing between paying their electricity bill or buying food, unless they take substantial steps or preventive measures, warns Snoeck Henkemans.

SOUTH AFRICAN BUILDER MARCH 2023 44 QUICK-BUILD
(Right): Rent-to-own options are taking the South African solar market by storm. Price hikes and load-shedding are two of the more obvious drivers of residential solar power investment. (Above): Rein Snoeck Henkemans, MD at Alumo Energy.

“Crucially, home-owners and small businesses don’t have to be forever beholden to Eskom, as alternative power generation solutions such as solar are becoming increasingly accessible and affordable,” he says.

SOLAR IS NOW LESS EXPENSIVE THAN ON-GRID ENERGY

Currently, the average household consumes about 30kWh of electricity per day, or roughly R3 000 per month. Under the new tariff, the same household could pay around R3 560 per month.

Under the 18,65% tariff increase, solar will be less expensive than grid energy and will help free households from ongoing loadshedding issues.

“Solar energy is SA’s most abundant natural resource. We

have the opportunity to get most households 80-90% off the grid, with the option of using grid energy on days with exceptionally low sunlight availability,” explains Snoeck Henkemans.

NEW SCHEMES OPEN NEW DOORS FOR MANY

Rent-to-own options also make solar considerably more affordable. Under Alumo’s Silver R2 844 per month rent-to-own solar scheme with a one-time R16 647 initiation fee, the average household could purchase a Sunsynk 5kW inverter, two Greenrich 5kWh batteries and 12 solar panels with a three-year workmanship guarantee for less than the monthly cost of Eskom electricity.

This system has the capacity to run two fridges or freezers, a computer,

two TV sets, two microwaves, 15 LED lights, a kettle and a CCTV system for six concurrent hours on a single charge.

UNDERSTANDING MULTIPLE SOLUTIONS

Each household has different energy needs, which means that each one requires a unique solar solution. To find out what solar system will work best for you, based on your current electricity bill, try Alumo’s easy-to-use solar calculator here.

“The simple fact is that, if financed through a home loan or purchased through a rent-tobuy option, solar’s less expensive than Eskom direct or municipalsupplied electricity. Technological advancements and widespread adoption have made solar more inexpensive and reliable than ever before, finally providing the average consumer with a viable and cost-effective alternative to grid energy,” says Snoeck Henkemans.

An eco-friendly foam roof and solar-electric system make the house a model of sustainability.

The glass walls open on three sides for a novel take on the indooroutdoor living concept. Inside, a 30m heated indoor swimming pool is capped by a 21m² projection wall perfect for screening films.

STAR OF NATURE AND SCREEN

The home’s three large bedrooms each have their own en-suite bathroom with Boffi fixtures. The primary suite is currently equipped with a giant glass bed frame and features a five-star resort-inspired

bath with a soaking tub, floating vanities and a rain shower.

Situated on 27ha of desert, the home provides seclusion and oneness with nature.

With cameos in numerous film projects and more extensive coverage on Netflix’s The World’s Most Amazing Vacation Rentals, the home has been available as both a film location and a luxury Airbnb stay with a per-night price of $2 500 (about R44 600).
