AAAMSA Group News Desk 45th Annual General Meeting: 18 September 2019

In my report from the 23rd of August 2018, I mentioned the slump in the building industry in the past 10 years. Investor confidence in the South African economy has also diminished with bail-outs of struggling state-owned enterprises (SOE’s) like Eskom, SAA and the SABC. Credit rating agencies have indicated that over the past 5 years government could not stabilise the rising debt to gross domestic product ratio. High unemployment is still a major factor leading to low economic growth. Government together with its municipalities are not spending their budget on infrastructure and development. According to the National Treasury Budget Review published on the 20th of February 2019, most of the spending will be allocated to social development, learning and culture, health and community development. Late or no payments from main contractors to subcontractors has resulted in many companies closing their doors or retrenching staff. We have also seen many of the large building contractors opting for business rescue. All of this has resulted in very little trust in the main contractor which is not always at fault due to non-payments from the clients. We can ill afford at his point in time for any more of the bigger building contractors to go into business rescue. The 30-day payment of invoices was promised by Government but did not come to fruition in all cases with around R6 billon total outstanding invoices. This is not only for the building industry but for all industries. Minister De Lille’s campaign to ensure prompt payments were launched in June of this year and we are looking with anticipation if this will realise. A Governmental hotline for late payments has been launched. These are not the only challenges facing a dwindling building industry. The so-called “construction mafia” has also played a role in projects being delayed and main contractors and sub-contractors forced to pay a ransom for not employing local communities. A lot of talking, and promises are being made but no actions. The above sketches a very negative outlook for the future but we need to stay positive and be smart in how we conduct our business. Our members rely on main contractors and we need to manage our affairs in such a way that there is no confusion when it is time to be paid. Make sure you read your contracts before signing them and that all your paperwork is up to date. On a more positive note, our membership has increased to a total of 1710 members across all Associations. SAGGA and Fenestration still has the bulk numbers but SABISA’s membership is growing rapidly.

Russell Hampson - President AAAMSA Group

Certification has definitely played a role in the increase of our member numbers. The Building Inspectorate relies on these certificates to ensure that building regulations are met, and protects them and the public from non-compliant installations. I would at this time, like to thank all the past office bearers from the 2017-2019 period for all their hard work and participation in the respective Associations. Your contribution to our Associations is greatly appreciated. I would also like to congratulate the new office bearers for the 2019-2021 period, and wish you well for your new term in office. On a sad note, the Association has lost a stalwart and role model with the passing of Annemarie Featherstone on the 11th April 2019. Annemarie served on National Council from 2013 to 2019. Annemarie was well loved and respected in our industry and a true inspiration to us all. RIP. In ending, I would like to again thank Johan, our Executive Director, and his wonderful hard-working team around him, including his office staff and field officers, for their commitment and tireless work they do in promoting and supporting our association. And then finally, and most important, to you our valued membership, thank you for your continued support and faith you place in our association. Thank you.

3D CONSTRUCTION

Design Using Immersive Tech

Rapidly-changing technology such as virtual reality (VR) and augmented reality (AR) is not only having an impact on the architectural industry, but interior design and fit-out as well.

U

sing the Samsung Gear VR headmounted display, clients of Trend group are able to experience a 3D simulation of their project well before construction even commences. Digital tools are deployed to allow clients to understand their projects a lot better.

A powerful concept

Trend Group 3D architectural visualiser, Emily Clark, stresses that immersive design is a powerful concept. “There are a lot of good aspects that can be harnessed. Essentially it entails creating a virtual environment before a project kicks-off, in order to allow a client to visualise what it will look like in the end. It is beneficial in that it minimises risk for both the design and construction teams.”

Essentially, virtual reality entails creating a virtual environment before a project kicks-off, in order to allow a client to visualise what it will look like in the end Construction plans are, by nature, difficult for non-technical people to comprehend. Hence ‘immersing’ clients in a virtual environment gives them a much better understanding of what they sign-off on, thereby defusing any lack of clarity. A broader implication for the technology is how the digital footprint itself is impacting on the way that physical spaces are designed. The fact that any surface can be rendered interactive gives new meaning to the phrase of a ‘blank canvas’. This is a concept that designers are grappling with, especially given the rapid rate of advancement in this field. For example, Matterport’s Cloud 3.0 software makes it possible for anyone to create a 3D model of a real-world place, simply by using a supported camera and the Matterport Capture App. Once a scan

is complete, it is uploaded to the Cloud where powerful software converts it into a 3D model. A related development is 3D printing, which makes it possible to construct a 3D object from a CAD model, layer by layer.

Starting off with a base model

However, it is essential for immersive design to be integrated effectively into both visualising an environment and creating a physical space. The first step in the immersive design process is a space plan. As an office-design specialist, Trend Group has an existing build envelope available as a 3D model that it deploys as a base. It is here that materials and textures can be assigned, for example, and pulled through into a VR realm.

Construction plans are, by nature, difficult for non-technical people to comprehend. Hence ‘immersing’ clients in a virtual environment gives them a much better understanding of what they sign-off on, thereby defusing any lack of clarity Once construction commences, a project is documented further by means of photographs. Even if Trend Group begins with a 3D model, this is still documented fully, with the photographs used as a means of comparison, and also to determine construction progress. “We are always looking for new technologies and ways of working, and incorporating these into our own best practice,” Emily emphasises. Immersive design complements the design process intuitively, as it helps designers visualise in 3D. While this trend is more prevalent internationally at the moment, many local companies are starting to catch on.

erticArt was the material of choice when The Trinity Session, a creative production team, embarked on the curation of a sculpted representation of a crosssection through earth, showing the strata formed by tectonic plates shifting and colliding, to form the intricate patterns of geological formations.

An earthy, robust medium

Marcus Neustetter, a director of The Trinity Session, explains that this ambitious project called for an earthy, robust medium. Chryso VerticArt, a cementitious mortar which is designed for application to vertical surfaces, presented the ideal material.

A zero to 48 hour carving window ensured that the artists had sufficient time to perfect the application and sculpting processes necessary to create the required 3D effect The chemical makeup of VerticArt allows for a vertically applied maximum thickness of 150mm, making it ideal for relief three-dimensional artwork. VerticArt was applied in various thicknesses and then carved and textured using palette knives, trowels, chisels, straight edges and wire brushes, to the exact creative brief. A zero to 48 hour carving window ensured that the artists had sufficient time to perfect the application and sculpting processes

necessary to create the required 3D effect.

A realistic artistic rendition

The mural was intentionally not pigmented, resulting in a very realistic artistic rendition of a crosssection through the crust of the earth. This is further enhanced with focused lighting, giving the effect of an upwards journey though geological eons as visitors ascend the staircase. This project used 4,5 tonnes of VerticArt, covering 140m2, scaling a height of 15 metres (three storeys). It required the specialised skills of eight individual artists, in conjunction with the Chrysotechnical team and took seven weeks to complete. The scale, innovative material, product methodology and conceptual approach ensured that the programme was not just a financial prospect for the materials supplier and the artistic curating team, but rather an opportunity for upliftment and growth for many of the artists, including emerging creative talent. Neville Wearne, Chryso Southern Africa’s project manager for concrete aesthetics, says that VerticArt was developed to allow artists to create reliefs and textures, which can be sculpted and carved.

UPLIFTMENT

Rural School Gets a Redesign A school for farm community children has opened its doors on the outskirts of Worcester. The new Botha’s Halte Primary School is the result of a private-public partnership that harnessed top level educational, commercial and design skills and experience to make the much-needed rural facility a reality.

T

he Botha’s Halte Primary School design was undertaken by architectural firm Meyer & Associates, a practice with an extensive range of national education sector projects under its belt.

The Botha’s Halte school design applied ecological and sustainability principles, while respecting the cultural heritage of the area According to architect Tiaan Meyer, the Botha’s Halte school design applied ecological and sustainability principles, while respecting the cultural heritage of the area. “These considerations influ-

enced the architectural form of the buildings but are also made visible throughout the complex and as such form part of the teaching and educational processes, therefore a didactic approach has been followed in the architectural design of the buildings,” he says.

Blending ito the landscape

The external colours of the buildings are recessively dark, to blend into the landscape, with only minimal bright accents. However, the historical components remain in their original white. “To the one side, the Anna Zaal reflects the link with the lime washed building traditions of the past, and on the other, the tower represents a symbol of a green and increasingly ecologically sustainable future,” concludes Tiaan.

ALTERNATIVE ENERGY

A Big Win for Commercial Landlords

W

hile the cost of installation has been prohibitively high in the past, SolarSaver has removed the need for capital investment through a rentto-own model and is currently installing systems countrywide. Businesses pay only for the greener, less expensive energy produced.

Passing cost savings on to tenants

“Forward-thinking landlords, retailers and property developers are catching up with international counterparts in seeing the potential to use solar installations to help attract and retain tenants. Solar installations allow landlords to pass utility cost savings to their tenants, in addition to providing them with an attractive, eco-friendly offering. Tenants are increasingly conscious of their carbon footprints and greener buildings regularly attract higher rentals,” says Lance Green of SolarSaver.

Solar installations make particular sense for retailers as they require energy consistently during the day, seven days a week, with demand usually peaking at midday “Retail malls or commercial properties with lots of under-used roof space are ideal for solar power generation. These installations make particular sense for retailers as they require energy consistently during the day, seven days a week, with demand usually peaking at midday. This mirrors daylight hours when the supplementary energy produced by grid-tied solar installations is available.”

system at Lifestyle Mall in Rustenburg last year. Since then, the system has produced 387 840kWh of electricity, supplementing roughly 20% of the mall’s power needs. Similar installations have been completed in Cape Town, Johannesburg, Durban and Windhoek. A new 1 megawatt (1MW) installation was completed at 17 200 square metre Mtuba Mall in northern Kwa-Zulu Natal in July this year. The anticipated solar output from that system is 1 528 200 kWh per year, which will go a long way to reducing the property’s utility costs.

Gearing up to go off grid

Shopping malls also need consistent electricity supplies to do business, and while grid-tied solar does not offer protection against load-shedding, adding batteries to the installation is the logical next step for many of these businesses. “Retailers like Mtuba Mall are taking a long-term view. Installing a solar solution means they get the immediate cost-saving benefits, as well as the potential to link batteries to the system that is already in place to allaw for going off grid in the future,” concludes Lance.

CHALLENGING ENVIRONMENTS

Building in SA’s Current Economic Climate New brick shades and 100 million bricks a year from a new R800 million plant – just some of what’s keeping Corobrik busy in 2019

B

uilding is a tough industry to be part of in SA in 2019, but that hasn’t stopped Corobrik from forging ahead with new shades of bricks and a new plant. ‘Architect & Specificator’ met up with Dirk Meyer, chief executive officer at Corobrik, for an industry checkup and news on latest developments. Dirk begins by acknowledging the challenging environment, something we cannot avoid.

Dirk Meyer

“The building industry is in the doldrums, at the moment,” he tells us. “For instance, only nineteen of our top forty customers from three years ago are still in business”.

Ten years ago the average brick weighed 3kg, now we have it down to 2.2kg

Such a dramatic reduction in customer numbers makes it difficult for suppliers to stay in the game. But, Corobrik has relied on its experience, expertise and quality product and staff commitment to meet the challenge.

Keep it lean in tough times

“From a business point of view we’ve kept pretty lean, because we know what the building industry is like. We’ve been through all the cycles of the SA building industry over many years and we’ve always survived.” Many businesses will give themselves a big tick for surviving the down cycles. That’s not good enough for Corobrik. “We’ve come out of every downturn stronger than we were before,” Dirk points out. “We’ve set ourselves up to be successful in the current South Africa.” One of the keys to that success is the company’s empowerment credentials and staff ownership programme, which has given staff a reason to build the business. “Our staff trust holds 26 percent of the share equity of Corobrik,” Dirk says. The Corobrik Staff Trust, established in 2008, is unique in that it is unencumbered of debt, so the trust owns the shares outright, and every employee with more than one year’s service becomes a beneficiary. Many of the staff members have been with the company for more than 20 years. Dirk started in 1986 as a marketing intern. “The staff trust has changed the behaviour of the business. Staff are shareholders so they understand the business imperative, and are motivated,” Dirk says. Corobrik also has other BEE shareholders who, together with the staff trust, hold in total nearly 50 percent. The company has a BEE level 4 ranking, which Dirk says they are looking to improve. He says the trust, BEE ownership and credentials show the company is truly South African. “For any builder and developer it is a good story – they know we are focused on and committed to South Africa.” With BEE sorted, staff empowered and a challenging business environment negotiated, the focus moves to the future.

building standards such as Australian, EU and American, so our quality and standards are measured against the best in the world.”

The black brick contains some iron, so is slightly heavier than the beige counterpart, and was inadvertently named by enthusiastic buyers.

This is important for specifiers, architects and consumers who have some security in that they are getting superior value.

“We didn’t know what to call the black brick, so ran a competition and got some good names and ideas. In the interim, customers came in asking for the black brick, so now it is known as the black brick,” he explains.

“We’ll never be cost leaders or the absolute cheapest in the market, but our value added element such as the reduced environmental impact and carbon emissions are substantial.”

Long-term view

“Our competitive advantage is that we take our business seriously, but not ourselves too seriously and we try and innovate and keep at the leading edge all the time. We have a culture where people can think and innovate and are encouraged to make continuous improvement.”

“Our strategy is we don’t believe in revolution but in perpetual evolution. We are always trying to improve our products, service levels to customers, and reduce our impact on the environment,” he shares.

One of the best examples of this is the weight of a brick.

Colours aside, the humble brick has a heritage many other products would envy – it’s been around forever and has stood the test of time. Enduring popularity hasn’t stopped Corobrik from looking to improve the brick, beyond the addition of modern shades.

Colours aside, the humble brick has a heritage many other products would envy, it’s been around forever and has stood the test of time “Although the industry is in a torrid state we’ve taken a long-term view and are busy building a new factory in Driefontein, just west of Carletonville.” The factory represents a two-year R800 million investment, will employ around 60 people and will be one of the most modern factories in the world. “We’ve used the latest tech and our customers can expect a brick of improved quality, at a competitive cost and reduced load on the environment. “Our new kilns use about 60 percent of the gas per brick relative to our old kilns. So there is a massive reduction in carbon load,” he claims, “The new factory is quite automated and uses more sophisticated technology. We are upskilling some of our existing employees to work in Driefontein, giving preference to BEE candidates.”

100 million bricks per year

The economies of scale are impressive. The factory’s output will be around 100 million bricks a year compared to an average of around 40 – 50 million a year. “We export product and come up against various

“Ten years ago the average brick weighed 3kg, now we have it down to 2.2kg.”

Benefits

It may not seem that significant until you add up the benefits. “You can dig a smaller hole in the ground which means there’s less environmental impact. There’s less machinery involved and fewer tonnes of clay and less gas to burn the brick. Plus you can get more bricks per tonne on a truck.” All of which reduces the carbon footprint considerably. And if you are on wheelbarrow duty, a lot less load on the back!

Conclusion

We started off our conversation with a look at the dismal state of the SA building industry. The question many ask is what now? “I think it is important in all the turmoil to focus on the intent and direction. Someone once said to me when you sweep a room clean there is a lot of dust in the air, but the room is clean. This is what we are seeing now in South Africa. We are encouraged by the direction of events and in due course believe the results will follow.” Dirk isn’t expecting 20 or 30 percent growth numbers, but as he points out there will always be a market and there are so many people who need quality, safe and secure housing. “I think the recovery will be slow and steady. But when it gains momentum it will become exponential,” he concludes. Corobrik Dirk Meyer Tel: (011) 871-8600 Email: info@corobrik.co.za www.corobrik.co.za

Cape Building to Improve Lives The Conradie Better Living Model project is aimed at improving the lives of Western Cape residents. Mark Schonrock, property development manager at Concor, says the new housing model is a real game-changer.

The project is located on the 22 hectare site of the former Conradie Hospital near Pinelands,” Mark says. This residentially-led, mixed-use neighbourhood development will prioritise integration, sustainability and affordability.

The core of the development is between 3 500 and 3 600 housing units, of which about 1 760 will be grant-funded

to Cape Town’s CBD, for families earning between R3 500 and R22 500 per month. Sports facilities, a community hall and schools for 1 600 learners are on the plans, as well as up to 60 000m² of commercial space and 15 000m² of retail space. A three-star or four-star business hotel, with 160 rooms and 500m² of conferencing facilities is also planned. The town planning scheme will incorporate substantial green belt areas with recreational facilities.

Easy access

An important benefit of the site is its proximity to public transport. It is within walking distance of both the Mutual and Thornton railway stations.

Concor Construction has been tasked with executing the full development of the project. This includes all town planning, detailed designs, sales and marketing, funding, construction and handover to end-users. The multi-million rand initiative is being developed as a partnership between the Western Cape Government, the City of Cape Town and the private sector.

There is also the potential for expanding other public transport modes, such as the MyCiti bus service. It is hoped that good access to public transport will make residents less reliant on private vehicles. The site will also have interconnected footpaths and cycling infrastructure as part of an integrated non-motorised transport plan for the area.

SECURITY

Smart Buildings Under Threat Almost two in ten (26.5%) computers used to control smart building automation systems were subject to some kind of malicious attack in the first half of 2019 according to an overview of smart building threats conducted by Kaspersky. This study shows that while it is unclear if such systems were deliberately targeted, they often become a destination for various generic threats. Despite not being sophisticated, many of these threats may pose significant danger to everyday smart building operations.

S

mart building automation systems typically consist of sensors and controllers used to monitor and automate the operation of elevators, ventilation, climate controls, electricity and water supplies, fire alarms, video surveillance, access controls and many other critical information and security systems. These systems are generally managed and controlled via generic workstations, which are often connected to the Internet. A successful attack against such a workstation can easily result in the failure of one or several critically important smart building systems.

While these figures are relatively low in comparison to the wider threat landscape, their impact should not be underestimated. Imagine if credentials from a highly secured building are stolen by a generic piece of malware and then sold on the black market. Or a sophisticated building’s life support system is frozen because essential processes have been encrypted by yet another ransomware strain. The list of possible scenarios is endless. In order to protect a smart building from the risks of cyberattack, Kaspersky advises that all computers are protected with a reliable security solution.

Converting Older Buildings Into Housing is a Hot Topic for Fire Safety

SAFETY

The City of Johannesburg has announced an ambitious plan to convert 500 dilapidated buildings into affordable accommodation over a two-year period to stem a critical housing shortage. However, repurposing or adapting older buildings poses unique challenges in terms of firesafety requirements, according to ASP Fire CEO, Michael van Niekerk.

T

he fire engineering specialist has been contracted by the City of Johannesburg to undertake a detailed survey of older buildings that it can target in this regard, including Brixton and Newtown. The company is also involved in a project to ensure the regulatory compliance of one of the oldest buildings in the city, believed to have been built in the 1830s. Interestingly, Michael points out that buildings constructed in the early part of the latter century were actually built very well. Construction methods were robust and, to a large degree, over-specified. This was largely due to the fact that the quantity of steel and concrete used was far in excess of modern requirements, where advances in materials science have meant that safety margins can be calculated precisely.

Escape routs

While the structure of older buildings may be sound, the challenge lies in the increased number of occupants as their purpose changes, as this means ensuring there are sufficient escape routes in place. Sometimes this will involve adding external staircases. “Even a historic building has to be made safe for occupation, and here the onus falls squarely on the owner. If it cannot be modesafe, then the number of inhabitants has to be limited accordingly,� Michael explains. Other factors that have to be taken into account are adequate fire-alarm systems, sprinklers, and fire doors to compartmentalise areas from smoke and fire to allow occupants to evacuate safely and rapidly in the event of an emergency. Emergency lighting also has to be factored in, especially as many of these older buildings have poor wiring. Apart from older buildings having a problematic internal layout, they are crowded together in the heart of Johannesburg, and often do not have an adequate safe distance from each other as a result. This increases the likelihood of a fire propagating in one building spreading to the next.

Crowded

Also related to fire safety is the issue of an adequate

water supply. Multi-storey office or commercial buildings converted to residential use are densely populated, which increases the stress on an already constrained water supply for firefighting purposes.

Apart from older buildings having a problematic internal layout, they are crowded together in the heart of Johannesburg, and often do not have an adequate safe distance from each other as a result In addition, the buildings themselves have to have an adequate distribution system in terms of pumps and tanks. A cost-effective alternative in this regard is to adopt the industrial-park model, whereby a single pump set and tanks can service a range of buildings. It would be beneficial for the whole of the CBD if adequate, guaranteed fire water supplies could be available for each building.

CONCRETE VS ASPHALT

Creating Attractive Parking Areas Concrete offers several major advantages when it comes to the construction of parking areas, says The Concrete Institute’s Managing Director, Bryan Perrie.

B

ryan says, in the first place, maintenance costs of concrete parking areas are minimal with only some joint sealing and cleaning usually required annually. “Asphalt parking surfaces, on the other hand, need to be treated every few years and totally resurfaced at least every 10 years. Such maintenance work can be very disruptive to the operations of a commercial shopping complex or office block,” he states.

Expensive maintenance

Studies in the USA have shown that over a typical 20 year life of a parking area, concrete requires very little maintenance expense while maintenance for an asphalt lot ends up as much as 80% of the initial construction cost. On a Florida, USA, project, an asphalt parking lot, in fact, ended up costing twice as much after 20 years than a similar concrete facility. Lighting of the parking areas also can be reduced through the use of light-coloured concrete surfaces. It has been estimated that three out of 10 light fixtures can be eliminated without losing the level of lighting in a parking lot when using light concrete surfaces. “With crime a constant problem in our country, the lighter concrete parking lots create safer storage of cars while reducing energy costs,” Bryan explains. The lighter coloured concrete also lowers tem-

peratures in parking areas during the hot South African summers, and by eliminating the ‘heat island effect’ can even lower cooling costs for adjacent buildings. Concrete parking areas particularly those with brushed finishes are more skid-resistant and allow for easy installation of rumble strips. Concrete pavements do not rut or develop potholes when carrying heavy loads.

Asphalt parking surfaces need to be treated every few years and totally resurfaced at least every 10 years. Environmental benefits

“The environmental aspects of concrete parking lots should also not be overlooked,” Bryan states. “The run-off is low in toxicity and cooler than from asphalt surfaces. Moreover, permeable interlocking concrete pavements substantially reduce run-off which overseas is now increasingly enforced through legislation. What’s more, to add to the sustainability point of view, the concrete mix used for parking lots can include recycled materials such as slag, fly ash, and recycled concrete.” The practical considerations of laying the parking area also favour concrete: concrete pavements are built in one layer, usually on a sub-grade of compacted earth. Asphalt pavements, on the other hand, require an additional gravel or crushed stone base. “Then there’s the question of appearance. The selection of concrete to pave a parking area offers the designer unlimited choices of texture, pattern, and colour for aesthetic appeal and the parking areas can be blended with adjacent greenbelts or equipped with water features. Large parking areas can be made more interesting through the use of colour, and colour can also be used to

They serve as attractive welcome mats for offices, sports stadia, airports, shopping centres and demonstrate quality to visitors, even before they walk through the front doors,” Bryan concludes.

Corrugated sheeting was repurposed as an external skin

Earthmoving Equipment and a Head Office in One How do you design a world-class showroom for earthmoving equipment while also accommodating a corporate head office in the same structure? This was the challenge posed to Paragon Group by developer Eris Property Group for the new corporate head office and showroom for Barloworld Equipment.

Given the micro location of the site, we knew that we needed to provide a truly distinctive structure that required out-of-the-box thinking to push the boundaries of what is possible. Paragon Group was approached to assist us in realising this vision,” Eris Property Group Development, Aashen Lalloo comments.

A bubble design

“It was a unique project in that we had to design an office environment and integrate it with a building big enough to accommodate large earthmoving equipment,” Paragon Group Project Architectural Technologist, David Cloete comments. Thus, the showroom typology eventually focused


on a ‘bubble’ design that essentially mimics the curved shape of an excavator tread, a signature Caterpillar machine. While the shape provided the volume and extent that such a showroom required, it naturally posed a lot of structural challenges. “Our idea of maximising grid distances and using steel as the main structural framework enabled us to maintain the integrity of the ‘bubble’ design,” David explains. Another important design decision taken early on was that the 4 500m² project would consist of two elongated buildings, namely a double-storey ‘north’ building, and a three-storey ‘south’ building, linked by an enclosed, glazed bridge. The buildings sit lightly on a landscaped podium that floats above

An important benefit provided by the ‘bubble’ shape is that the canopy of the top edge has a cantilever of about 3.5m, which not only gives excellent shading in summer, but is exposed in winter, which heats the internal space naturally. a semi-basement parking level.

A single high-rise building was not feasible due to factors such as height and bulk restrictions on the industrial site, as well as its close proximity to OR Tambo International Airport building blocks, while adhering to the prevailing restrictions. David points to material selection as another deciding factor. “We pushed the boundaries of what the industrial aesthetic had to offer in terms of materials.” Here standard corrugated sheeting, prevalent in Isando as a roofing material, was repurposed aesthetically as an external skin.

Performance glass

Perhaps the most important element of the design is the façade, which gives the main view onto the showroom. A flush-glazed unitised façade with performance-glass specification was opted for. An important benefit provided by the ‘bubble’

shape is that the canopy of the top edge has a cantilever of about 3.5m, which not only gives excellent shading in summer, but is exposed in winter, which heats the internal space naturally. Another challenge was the clay-type soil conditions, which are not ideal for a building foundation. Given the design complexities, a grid layout was key. The engineers devised a connected raft foundation between the columns in order to ensure the building’s structural integrity, and to cater for any external movement. The project broke ground at the end of 2018, with the showroom building nearing completion. The head office building is scheduled for completion by year end.

the site-wide requirements under the sustainable precincts tool, which was developed to influence and incentivise developers to consider good design, community and environmental outcomes. Credits within the tool, under the categories governance, liveability, economic prosperity and environment are intended to assist in site selection, site analysis and site layout and include benchmarks for engaging with stakeholders in site planning. Site-wide green infrastructure, in terms of both hard and soft works, is also encouraged. As part of the precinct’s ongoing sustainable

management initiatives, a community users’ guide was developed to give occupants the tools and knowledge to efficiently operate all service and management systems. The Guide describes all green initiatives that have been implemented with the intention of enhancing environmental performance and minimising environmental impact and harm during Sandton Gate’s operational lifespan. This includes ensuring that all future alterations, additions and programme changes are consistent with the vision of the users’ guide and the health of the environment.

Community management

Annelide Sherratt, senior sustainable building consultant at Solid Green Consulting, observed that the mixed-use project received its certification just in time for the GBCSA Convention 2019, which was themed ‘Beyond: Shaping Cities of Tomorrow’.

A community users’ guide was developed to give occupants the tools and knowledge to efficiently operate all service and management systems “This development is a precedent study of what it means to go beyond certifying buildings to apply sustainability at a precinct scale. The project has also gone beyond the limits of the precinct boundary and has committed to the upliftment and upgrading of the Braamfontein Spruit and park adjacent to the site, which will be managed together with the surrounding community.”

Accessibility and non-motorised transport

The precinct plan has been strategically designed to incorporate adequate non-motorised transport (NMT) facilities. An extensive network of walkways will be provided between the residential, commercial and business components, with a shared pedestrian and cycle path along Minerva Avenue to promote the integration of non-motorised transport. Raised pedestrian crossings and universal access design at the internal intersections will supplement the connectivity for NMT users between the various land-uses. In addition, Minerva Road will have a cul-de-sac at either end to restrict through-traffic and provide a safe pedestrian/ cyclist environment. Current and future public transport connectivity includes access to the Gautrain Bus Route S4 Randburg-to-Sandton, Gautrain train and bus routes from Sandton Gautrain Station and the Rea Vaya BRT system, where a trunk route and additional three BRT stations are planned for the vicinity.

The synthetic gypsum used in MetaCote, by contrast, is sourced as a by-product from phosphate fertiliser manufacture. “Synthetic gypsum is also more ecofriendly as a binder, when compared with cement,” he explains. “The production of one ton of gypsum binder generates one tonne less CO2 emissions and avoids the depletion of a further 1,5 tonnes of natural resources when compared with cement.” OMV Gavin Coulson Tel: (018) 484-4388 www.omv.co.za
