ENERGY EFFICIENT SYSTEMS FROM THE AAAMSA GROUP The building envelope provides the thermal barrier between the indoor and outdoor environment, and its elements are the key determinants of a building’s energy requirements that result from the climate where it is located. The building envelope controls heat gain in summer and heat loss in winter. 1. FENESTRATION Fenestration affects building energy use through four basic mechanisms - thermal heat transfers, solar heat gain, air leakage, and day-lighting. or

2. THERMAL WINDOWS Window technology has evolved over the years choosing the right ‘performance glazing’ (energy efficient glass) allows one to control how much heat enters or escapes from a building.

A new calendar year lies ahead of us which is full of promise for our Industry’s growth. The building regulations together with mandatory material standards will enhance building safety and the use of quality building materials. What is now required is that the National Regulator of Compulsory Specifications implements the required inspections to enforce compliance. In addition, the Construction Industry Development Board is set to publish its Prompt Payment Regulation which will assist with the cash flow of the participants in the Construction Industry. The requirements for the efficient use of energy are here to stay and industry will adapt more and more to meet the required product standards. All the above will be felt throughout our industry from material manufacturers through distributors to the contractors. Every participant will experience the change and growth. All the above is supported by Conformance and Test Certificates by the AAAMSA Group under the individual Association banners. We wish all our readers, members and stakeholders a Prosperous and Healthy 2016 and take this opportunity to thank all for their support and loyalty in the past. We wish all our members well into the future. Hans A Schefferlie Executive Director

The EnTF was awarded the contract to train 90 Certified Energy Managers (CEM) for the Zimbabwe Energy Regulatory Authority (ZERA). In 2015 the first 30 were trained in Harare, to be followed by 30 in Bulawayo in April and the last 30 in Mutane during May 2016.


Non-technical personnel were trained with customised material at the popular Neogesi energy auditing firm. The basics and fundamentals of energy and energy efficiency are taught while the managers review their company’s current systems and processes, so as to develop energy auditing methodologies and systems for their company to trade optimally. The training was highly successful with positive feedback and major improvements in staff skills and company processes.



A proud association with a government department in Limpopo has seen EnTF customising its training to meet the Limpopo Green Strategy implementation requirements. For two years, we have trained and upskilled learners from the province through customised training sessions, practical implementation and mentoring sessions. Currently, we are mentoring the learners while employed in their positions to implement ISO50001:2011 and the related projects. Limpopo Province should be commended for this initiative. The students have in total received 10 ECSA CPD credits and are also working towards their EWSETA credits for Building Energy Auditing (BEAT). These are just a few examples of the customisation you can expect from the Energy Training Foundation.

Sustainably Ingenuous with a Green Code of Practice Green Code Designs is an architectural firm based in Johannesburg with an impressive portfolio and extensive national map. Sean Duarte, co-founder of Green Code Design, tells ‘Architect and Specificator’ that the idea of establishing a firm first came up in the school playground.

My partner, Sean Brunke, and I have been friends since Grade 01 and, barring some divergent life courses into travel and studies, came together again while completing our studies at university. Once we finished our degrees, Sean went to gain work experience here while I went to Zambia to project manage a large construction project. When we both gathered the experience we needed, we felt it was time to start our own firm that matched our beliefs, and Green Code was born in 2011.” Sean Duarte (left) and Sean Brunke

The company specialises in sustainable and contemporary architecture, providing clients in both the residential and commercial space with inventive designs that map back to their focus on green and environmental awareness.

Inspire and design

“We use solar power or natural lighting wherever possible and try to incorporate grey water systems when their installation is both feasible and within budget,” says Sean Duarte. “We believe that part of our role is to educate our clients as much as possible and show them how far they can go, and how much they can benefit, from sustainable methods. The cost of many of these solutions is high so we do what is realistically possible.”


Both partners are committed to ensuring that projects are crafted to fit within budget and to the highest standards. They are also focused on creating architectural solutions that veer away from the expected and instead tap into the South African zeitgeist. “We avoid the European-inspired Tuscan design preferring African contemporary,” explains Sean. “It is important to create something unique that we can be proud of. We don’t want to copy other countries, instead we want to pull from our environment, history and culture and to be a part of developments that embody South Africa.” He believes that South Africans are becoming very aware of the value of sustainable and green architecture and that they also want individuallyflavoured styles as opposed to the typical, cookiecutter ones which dominate the current landscape. “People are more willing to explore new ideas and eco-friendly styles, which is good news all round.”

and leadership skills,” explains Sean Brunke. “We help our clients to tick all of these boxes and assist them in identifying the right sub-contractors so their project is successful and to code.” This service is available to all the firm’s clients and Green Code Design has also been contracted by a number of other firms that require this level of project management. Throughout the process, the team ensures that budgets are met, buildings go up and every aspect is to the highest possible standards.

Managing a construction project to any scale takes significant organisational, time management and leadership skills

Managing the odds

“We have worked with a number of well-known local developers across a broad spectrum creating townhouses, freestanding houses and apartment blocks,” says Sean. “Projects are quite varied some are middle-income flats while others are high income apartments valued at R10 million each.”

“Managing a construction project to any scale takes significant organisational, time management

One of the developers which caught the firm’s attention is MS Development in Johannesburg. The company is edgy and keen to push the boundaries of architecture, something that sits very well with the Green Code ethos.

Green Code Design offers project management services to clients which works perfectly in parallel with the architectural side of the firm.

Three developments

Currently, Green Code Designs is working on three developments in Athol, Rivonia and Bryanston and has recently completed commercial designs for shopping malls in Boksburg, Alexandra and Johannesburg South. One of the projects they highlight is a highly specced house in the new Waterfall Estate. “We’ve created more than ten houses in the Waterfall area, some in the country estate and others in the village,” adds Sean. “The one we really enjoyed working on spanned 650m2 with the highest spec finishes, a hugely contemporary design and sustainable installations wherever possible.” The practice has also recently worked on a conceptual project through a body called the Drugs and Crime Free Foundation. The group has investors and government support and looks set to move ahead with a R200 million rehabilitation centre

he overall theme of the awards was education. Entrants had to submit online ‘movie’ entries in one of three categories: Built, Future and Adopt. In addition to the three winners, a ‘Best Movie’ winner was named for the best entry; and a People’s Choice award for the entry that received the most online votes. “Architects play a special and pivotal role in the future prosperity of South Africa,” said Evan Lockhart-Barker, MD of Weber Saint-Gobain in his opening address for the event, attended by “Architect & Specificator”. “The awards really promote and celebrate architecture that positively affects the integration of community and environment for the long term benefit of both people and planet.” Andy Hart, of the South African Institute of Architects, added, “It is wonderful to be able to highlight and celebrate a truly good initiative. A total of 38 entries were received which is pretty fantastic.” Unique to the Social Gain Awards is that only digital entries were permitted, and students and professionals competed for the same awards. There was global interest in the awards with 538 unique visits from the US and 487 from Germany recorded on the site. The judges also noted that the awards saw a new wave of up-and-coming architects entering the fold. The judges looked specifically at building projects in one of three areas:

In 5 D Building Information Modelling is transforming the design process of buildings worldwide offering savings on construction costs as well as operational savings in terms of waste, water and energy use. Combining BIM with other developments such advances in data analysis and cloud-based collaboration also open up exciting potential to reshape the way engineers, architects and designers collaborate on future projects.


ather than simply creating a physical model of a building, architects, planners and designers now have the capability to work together and test every aspect of a building in a virtual world, before any work on the building even starts. The advancements in technology allow everyone involved in a project to examine different elements of the build at the same time. For example, to try out different building materials, plot heat emissions and examine how people are likely to move through the space, years before starting the actual construction.


3D modelling is becoming the norm, enabling greater collaboration and real-time improvements to designs. For example, if a column is moved in a building, the ventilation ducting has to be rerouted – 3D modelling highlights this immediately, preventing any disturbance at a later date.

More data is available than ever before about other similar buildings already in use which can be drawn into the design process This new way of modelling doesn’t only affect the appearance and functionality of evelopments but also enhances their environmental sustainability. BIM enables the assessment of everything from heating and air-conditioning systems to the potential for using natural light and ventilation – something that has not been available to assess to its full potential previously. Architects, engineers and designers are increasingly embracing the creative freedom that 3D building modelling offers. This technology was used for the planning and construction of the Chinese National Aquatics Centre (Water Cube) for the Beijing Olympics. It enabled architects to assetmanage every element of the design, down to the smallest door handle or light fitting, predicting the effects of any change made to the building.


Next up is 4D and 5D. 4D modelling aligns the 3D models to time, allowing them tobe controlled and manipulated to show the building as it should appear at any stage during construction.

4D technology played an integral role in the development of Heathrow’s Terminal 5, saving the project £2.5m in the first nine months of use. The technology helped in bringing together the design and the con-

struction team to resolve problems before they escalated – crucial when construction is underway at one of Europe’s busiest airports, with millions of passengers travelling through each year. When it comes to crowded public spaces, such as airports, it is vital to take the flow of movement in the building into consideration when designing the area. This is where Arup has developed MassMotion technology to predict the movement of occupants in different buildings and on roads. Each character has its own artificial intelligence, which enables the prediction of possible behaviour of passengers and pedestrians in real life. All characters are unique and make decisions based on their surroundings, as they move from one environment to the other in real time. For instance, the movements of the economy class and business class travellers differ greatly and can create previously unforeseeable congestion hazards.


5D is the next phase which models costs and enables well-informed financial decisions as a project evolves. Decisions about a change in material can be predicted and unforeseen impacts on other parts of a project anticipated. Advances in computing power and data analysis also mean that more data is available than ever before about other similar buildings already in use which can be drawn into the design process to take into account how occupants already use comparable buildings. It’s an exciting time for the building modelling practice in terms of seeing how the design and building performance evolves in the years to come. Tristram Carfrae, Global Board Director, Arup

Architect and lecturer, Mthembeni Mkhize, has been researching methods to improve on the traditional Nguni housing structure for the past few decades.

I visited Okhahlambeni area, Maphumulo, as a baby and then later in life,” explains Mthembeni, recalling the area that ignited his architectural passion and initial introduction to rondavels. “I wanted to contribute to improving the quality of life of the people living there.”

Offers all the fire resistance qualities that are particularly important in rural landscape settings and rondavel dwellings where open fires are often used for warmth and cooking He spent the next few years researching various traditional housing structures across the globe, visiting places such as Egypt and the US. “In 1994 I visited Arcosanti in Arizona, USA, where there is an urban design experimental project in the mountains overseen by architect, Paolo Soleri. I focused on the innovation of the design and environmental accountability,” he says, explaining that improved thermal designs decrease the need

for electricity, particularly pertinent in modern South Africa. This prompted the development of his latest project, The Meseni Zulu Homestead Laboratory Lessons for Cities, which seeks to improve the longevity of the mud rondavel by adding a brick “jacket” to the outer side. The project involved the construction of seven “show” rondavels in the mountain area of Maphumulo, with the outer brick layer of 2 000 of Corobrik’s clay face bricks added to each rondavel of the homestead.

Burnt apricot

“I opted to use Corobrik’s range of Burnt Apricot facebrick for the single layer of ‘skin’ to cover the mud brick construction,” says Corobrik’s Allin Dangers. The Burnt Apricot facebrick fits the project in terms of affordability, colour and texture and the required durability to ensure a long lifecycle. “It so happens this clay brickwork offers all the fire resistance

qualities that are particularly important in rural landscape settings and rondavel dwellings where open fires are often used for warmth and cooking.”

Soggy bottom

Mthembeni explains that one of problems with the traditional mud bricks is that they lack sustainability. “After the rainy season, the lower layer of the wall gets very muddy and each year, usually in December before Christmas when family is arriving, the community paints the rondavel again. This becomes very expensive.” The facebrick skin protects the rondavel from constant weathering and also negates the need for cement plastering and paint which is not only costly, but lacks longevity. Another important benefit of this construction method is the sense of pride that comes with living in a traditional building that has been enhanced with a facebrick finish. “The homes are set to meet the aspirations of the prospective homeowners to live in aesthetically pleasing houses which are built using quality materials that lend dignity and provide a sense of home,” he adds. Mthembeni says at the heart of the project is his true passion as an architect, which is to provide people with something of which they can be proud.

The stove has a chimney taking the fumes out the rondavel which means no chance of suffocation “As architects we look to create a product that will influence society at large, that can be used by millions of people and that improves quality of life.” Corobrik, Allin Dangers, Tel: (031) 560-3111, * Easy navigation through the site * Comprehensive archive * Free to users * No registration * Searchability Architect & Specificator is the official journal of the following organisations:

A Nod to the Past The Open Door restaurant at Constantia Uitsig Wine Estate has launched in Cape Town’s southern suburbs. Local restaurateurs Neil Grant and Barry Engelbrecht have transformed the space formerly occupied by The River Café - situated at the entrance to the estate - into an exciting destination dining spot.


rant and Engelbrecht also own the successful Cape Town eateries, Bocca and Burrata. Inhouse Brand Architects have successfully worked with the duo in the past and created the interiors for both Bocca and Burrata. The challenge this time was different, though: a far larger dining area, the introduction of a new culinary style as well as the logistics of dealing with a building that is a local heritage site.

Cultural landscape

Originally built between 1917 and 1918 as a primary school for children from the neighbouring farm areas, the building is an important part of the cultural landscape of Cape Town and could not undergo major changes to its exterior. The wellloved historic facade therefore remains, while the building’s interior has been thoroughly overhauled and given a more contemporary spin. The restaurant floor has been opened up entirely; walls that previously separated the main dining room and bar from the rest of the restaurant space have been removed, bathrooms have been moved to former administrative office space, and a striking new central bar and dining area created. The tasting room, which previously shared space with the restaurant, has been relocated to a different area on the estate and has thus opened up an additional room for the establishment. Similarly, the outside areas have been optimised through enclosing the courtyard in glass as well as the addition of a wooden deck to the side of the building. The result is a fresh space that can seat up to 180 diners at capacity. As opposed to the distinctive contemporary Italian fare for which Bocca and Burrata are celebrated, Open Door will offer a different kind of dining experience that places an emphasis on leisurely meals in a relaxed, informal environment.


The entrance to the establishment has been repositioned so that diners enter through the open space of the courtyard. Immediately creating a sense of openness, the lobby area is sheathed in glass with wooden beams covering the ceiling in an irregular fashion – signalling the relaxed ambience of the restaurant and lending an air of warmth and depth. This is continued into the main area of the restaurant

through the use of dark wood and a moodier colour that suggests elegance and sophistication, and elevates the space. Alongside the bar, the open kitchen draws visitors into the hustle and bustle of the space. Further idiosyncratic quirks such as the reclaimed doors and doorframes, which hang from the ceiling in the old tasting room, as well as the school memorabilia that is scattered throughout, are design aspects that enliven the atmosphere and serve to acknowledge the building’s history.

Emphasis on Training The glass and aluminium industry in the Western Cape is not immune to the pressures being exerted on the global economy. “Architect & Specificator” catches up with AAAMSA regional chairman, Regan Huisman, and SAGGA’s Renzo Schincariol to find out what 2016 holds in store.

Renzo Schincariol, Western Cape chairman SAGGA


espite the tight financial climate in the aluminium and glass markets in the Western Cape, both men remain upbeat about the future. “We have seen a good start to 2016 and early indictations are that it will pick up as we go,” says Regan. No-one is out of the woods yet but there is a definite improvement from last year.”

Made concerted efforts to ensure that inspectors know what to ask for and when to query an installation There is no doubt that 2015 took its toll on the industry at large, adds Renzo. “Businesses do not have a lot of cash to play around with. Everyone, to a certain degree, is still in survival mode. Because of the weak Rand and the general economic situation, we are fast getting to the point where our industry just cannot swallow the increases

anymore. Which is why price hikes are a definite in the coming months.” Explains Regan, “There were a lot of tenders out there, but they were all fixed around pricing. The right price was the deciding factor in who won the contract. Whether it was the right company for the job was inconsequential.” But, he says, with the ongoing weakening of the rand, the aluminium and glass industries are going to have to look at their pricing models in depth this year if they want to survive this particular storm. Aluminium has seen increases of around 15% and glass 10% just due to the weakening exchange rate. “A machine that would have cost R1,3 million a few months ago to import is now just under R2 million.”

Delivering value through education

With markets and industries under pressure, it is


more important than ever to offer reliable, consistent and value-added service. Therefore, training for the industry will remain a focus in the Western Cape for several years to come.

says Regan. “But we now want to step this up a notch and take it to the next level (competent persons category 1) as there are only a handful out there at present.”

“We have made major inroads with our glazing certification programme that sets about introducing standards and ensuring quality control in our industry,” Regan comments. “We believe there is room for an industry training facility where these, and other courses could be presented, but right now the cost of setting up such a facility is extensive, so this is still in the pipeline.

It’s not an easy process as it requires mentorship and practical experience. But, explains Renzo, glass is dangerous and not to be fooled with. Improved training and heightened competency should be welcomed.

“However, training the industry at large, over and above manufacturers, producers and installers, has paid off. It’s not just about setting the standard for our own people, but also our clients. Giving architects and designers insight into the glass and aluminium industry is just as important, as is the training of building inspectors who need to understand the requirements and the standards. “For several years, more and more businesses have opened their doors even when they are not owned or run by manufacturing or installation experts. With building inspectors informed of standards such as the glazing certificate programme, there has been a definite move towards enforcing these requirements. Both Sagga and Aaaamsa have made concerted efforts to ensure that inspectors know what to ask for and when to query an installation,” says Renzo.

But we now want to step this up a notch and take it to the next level (competent persons category 1) as there are only a handful out there at present “It’s all about well-trained manufacturers and installers who are able to deliver an improved service to a set industry standard. Our call for more regulation is simply to ensure everyone is on the same playing field while ongoing investment in training ensures that we are able to deliver on what we promise. “ Regan Huisman, Western Cape chairman AAAMSA, Tel: (021) 905-2170, Email:, Renzo Schincariol, Western Cape chairman SAGGA, Tel: (021) 556-3036, Email:,

Regan concurs saying that for far too long, there has been little or no acccountability with the buck being passed around when things go wrong.

Competency and experience

Another key focus area is that of competent persons. “This applies not only to new people entering this industry but also to the old-hands. In 2015, we encouraged the old and the new guard to sit for the competent person training course. Several people have completed the initial training (category 2),” Architect & Specificator

KLIP-TITE - ONLY FROM GRS Developed through continuous in-house testing of Klip-Lok 700, it was evident that failures occurred due to deflection of the pan during high wind loads causing the sheets to disengage. The following improvements were thus developed: • Transverse stiffeners were introduced in the pan, to achieve a balanced system design. • Transverse stiffeners reduce the deflection of the pan, increasing the wind uplift resistance. • The ultimate wind-uplift resistance of Klip-Tite exceeds expectations. • Klip-Tite has retained the superb properties normally associated with Klip-Lok 700. • Transverse stiffeners are a first in the South African sheeting market.

First Multi-Storey, Concrete Block Development

ach block houses twenty five 35m² apartments comprising two bedrooms, kitchen/lounge, bathroom and balcony. Moreover, insulated roofing and solar heating are included to meet conservation requirements and reduce the cost of living for the occupants. In addition to the hollow-core concrete flooring slabs, Echo Group company, Topfloor provided precast staircases, as well as high-strength concrete blocks, modular precast concrete doorframes and windows and poly-fibre balcony railings.

Time-saving advantages

According to Power Group, director Johnny Moore, precast hollow-core slabs were an integral part of the structural design criteria and saved months in construction time.

One of the precast staircases supplied by Topfloor

Over 16 000m² of prestressed hollow-core concrete flooring slabs for the construction of Lange Formal Township, signifies the Western Cape’s first multi-storey, loadbearing reinforced concrete block-masonry development. Eighteen low-income rental apartment blocks are being built by main contractor, the Power Construction Group, which formed an integral part of the project’s architectural and engineering development teams.

“No shuttering was required nor curing time for wet concrete which meant that other services could begin work as soon as the slabs were installed. Further time-savers were the smooth soffits and rough finishes on the upper sides of the slabs. This enabled the soffits to be painted without the need for skimming and made screed bonding on the top sides hassle-free. All of these time-saving advantages meant substantial cost savings for the client. “Topfloor was involved in the primary as well as secondary planning stages and helped resolve details such as the staircase/slab interfaces and pull-up bars for the reinforcing of the walkway balustrades,” adds Johnny.

Seismic codes

The Lange buildings have been designed to comply with seismic codes which meant that Topfloor had to provide pre-cut openings for seismic-stress connections. In addition, the company supplied cut-outs for plumbing ducts. Another advantage of using hollow-core flooring is its superior thermal and sound insulation properties. The professional team which initiated Lange’s design concept was led by Dieter Boessow of Architect Associates. Together with Power Construction’s project engineers and consulting engineers, Aurecon, and independent construction consultant, Günter Koch, they succeeded in setting a new standard and establishing a new trend in cost-effective economic housing delivery in the Western Cape.

Towering Glass Transformation

Two tower buildings in the Cape Town city centre have gone from drab to fab thanks to an innovative team of experts. “Architect & Specificator” speaks to David Elliott of World of Windows, the company responsible for the retrofit of the glass façade on the buildings which have brought massive change to the Foreshore.


o-one would blame Capetonions for not remembering what the buildings at Merriman Square USED TO look like. Brown and boring would probably be the most apt description for the 12 and 23-storeys on Hertzog Boulevard close to the Civic Centre and Artscape. Covered in brown stone chips and decorated with red granite columns, they were as old fashioned as could be – eyesores so to speak. Now covered in shiny brand-new glass, the transformation is astonishing. Property-owners Redefine employed a highly skilled team of design consultants and contractors to transform the buildings. With a multi-million Rand budget, refurbishments meant upgrading the two towers to AAA-Grade and constructing a parking garage between them. The challenge, however, for the external envelope of the building was to modernise it without having to evacuate tenants or disturb them during the construction period.

By cladding the building in a unitised curtain wall system, major benefits have been achieved for the property owners including reducing the air conditioning costs by about 30%

Enter World of Windows, headquartered in Cape Town, with three decades of designing, manufacturing and installing aluminum windows, doors, shopfronts and curtain walls, behind it. With their host of technical expertise, superior project management and state of the art manufacturing


facilities including a SABS accredited powder-coating plant, the company was ideally positioned for the contract. “Refurbishing the façade of over 22 000 square metres of fully occupied building is, however, no easy task but we were up for the challenge and tendered for the contract that we managed to scoop.” Working with contractors Murray and Roberts as well as Pure Consulting, the façade engineers, it was clear that a bespoke solution was required.

Apart from the other benefits of installing from the top down, it ensured the building was immediately waterproofed and reduced scaffolding costs significantly “The engineers designed an innovative and original system for the retro-glazing of the façade – a unitised horizontal rail system,” says David. “Working from the top down, this saw the entire outer façade of the two buildings completely refurbished with minimum disturbance to the occupants, who occupied the building throughout the process.” The tenant co-ordination, removal of the old windows and installation of the new cills, was co-ordinated and managed by project managers, BFH De Jager, and Murray & Roberts respectively.

Delivering despite challenges

According to David unitised curtain walls, the term used to describe the glass and aluminum coverings installed on the two buildings, are by their nature designed to be installed from the bottom up. “Which is why Pure Consulting had to find an innovative solution to save scaffold costs and minimise the impact on the building occupants. This meant working from the top down,” explains David. The bespoke solution was designed by Pure Consulting’s engineers from scratch and was implemented for the first time on the Merriman Square buildings thanks to the contribution in design development from World of Windows. The innovative groundbreaking system not only saw the construction sequence reversed but also saved substantially on the budget. “Our job was to deliver on the design,” says David as they were responsible for the overall delivery of the façades on the buildings. “At tender stage, the key innovation was the optimisation of the unit size for glass stock sheets, thus making larger and fewer units that improved both the logistics and labour Architect & Specificator

required on site. By offering this revised façade modulation, we were able to be more competitive.” By cladding the building in a unitized curtain wall system, major benefits have been achieved for the property owners including reducing the air conditioning costs by about 30%.“Glass and aluminum are fast becoming the smart choice for modern buildings,” says David. “In this case they have not only transformed the look and feel of the buildings, but also positively contributed to the city skyline.

Logistics makes perfect

“From the very beginning, we decided to keep it as simple as possible and not bring complexity into the construction process,” he adds. “We manufactured all the units locally at our Cape Town factory which were then transported to the site, keeping to four or five storeys at a time. Each completed floor was handed over one by one to the main contractors for interior refurbishment. “The first step was installing the scaffolding and

two car lifts to allow us to move up and down the buildings. This took about six weeks before we could commence with the refurbishment. This allowed us to custom design and manufacture everything being used on the contract, from the trolleys moving the glass to the brackets holding it all in place.”

An extremely labour-intensive 18-month process with 60 crew working on site at any given time Once on site, Dave’s team first removed the existing granite from the building which was undertaken floor by floor as they moved down. The new arctic blue glass façade was created by coring holes to fix the dead load brackets and wind load pins into the concrete of the existing building, with alustruts that in turn hold the gutter rails. The unitized doubleglazed panels were then clipped and shuffled into place horizontally creating a weather and airtight seal. The panels are 1600 x 1 750mm in size. According to project manager, Stephen Young, one floor consisted of 220 panels weighing an average of 120kg per panel. “It’s really a very simplistic system but one that has to be installed correctly. There was no room for error. Safety was obviously a top priority though the build, easier said than done in a city renowned for high wind speeds.” Apart from the other benefits of installing from the top down, it ensured the building was immediately waterproofed and reduced scaffolding costs significantly. Once the outer façade of a floor was completed, it was handed over to the main contractors who then refurbished the old windows from the interior taking out the frames and installing new windowsills and blinds. This work was done at night so as not to disturb the tenants of the building. “As the outer refurbishments were all carried out during the day, we used coring instead of rotary hammers to keep the noise levels down, while keeping to our goal throughout the project of handing

over one floor to the main contractors every seven days,” says Stephen.

A welcome change

Along with the new glass façade, a series of fins was installed to create patterns on the buildings giving a dramatic effect. These decorative fins create abstract visuals of Cape Town landmarks such as Table Mountain, the Peninsula, Robben Island and Devils Peak. Fitted on the edges with LED lights, the shapes come to life at night. World of Windows was also responsible for covering the newly-constructed parking garage between the two tower buildings in an aluminum louvre system. “It was an extremely labour-intensive 18-month process with 60 crew working on site at any given time,” says Stephen. The choice of glass is central to the radical transformation of the two buildings, David concludes. “Through the optimum use of glass, a dated and tired-looking building has been changed into a slick and modern site with classic lines. A great addition to Cape Town’s Foreshore.” World of Windows, David Elliot, Tel: (021) 551-3235 Email:

Fit for Purpose We may be at the foot of Africa but that does not mean we can be fobbed off with international products that are unsuitable for our needs and our climate. “Architect & Specificator” talks to Geoffrey Green, marketing manager at Mapei South Africa, about this very thing.


n Italian-based multinational company, Mapei has some interesting plans afoot for 2016, not least of which is introducing new solutions that deliver directly to the demands of the South African market. The company currently has around 300 line items as part of their local offering with two new products being put on the shelves over the past few months. Each of these has been specifically selected for use in South Africa.

Some of our clients are delighted with the service while others are not keen to have us on site “If our sales or technical teams see an opportunity, we will identify the right products, specify, test and bring them in if suitable. We can and will provide a solution that works,” Geoffrey assures us. The manually-applied Purtop HA is one of the new Mapei solutions and extends the in-situ polyuria membrane waterproofing system. With a twocomponent, solvent-free formulation, this product has been designed to be applied by hand and forms a tough, elastic waterproofing membrane ideally suited to small to medium-sized flat roofs and terraces. “Waterproofing in our country is, obviously, a ma-

jor concern,” says Geoffrey. “Purtop HA adheres to many types of substrate and the final product is resistant to alkalis, dilute acids and detergents with superb tensile and tear strength.” Another product that stands out from the Mapei crowd is based on the well-known Mapelastic twocomponent cementitious mortar that has been on the market for more than 20 years. The Mapelastic Guard has been created from cementitious binders, special additives and synthetic polymers in water dispersion and is specifically designed to protect large concrete structures against aggressive atmospheric agents, moisture and salt solutions. This product can be trowelled on or it can be applied to large areas using rending equipment and spraying through a skimming lance. It is as robust and easy to use as possible, allowing for really seamless application and protection.

Supporting the specifier

“We carry out thorough technical evaluations to help our clients identify potential issues so they end up selecting products that are suited to their building requirements,” adds Geoffrey. “Our staff are trained to deal with specifiers and we focus on doing presentations and meeting with people so as to ensure they have the information they need to make informed choices.”

Architect & Specificator

January/February 2016



For Geoffrey, these relationships with specifiers and architects are essential to the growth of the business. “The last thing an architect needs is to go to site and uncover a problem they have to spend time fixing - it’s a hassle and costly. Our support guys are on hand from the beginning to help address and prevent any challenges.” At Mapei SA, the technical team can specify a solution off a plan and put forward recommendations alongside costs, budgets and requirements. This team is also on site continuously as part of the service offering from the company, thereby ensuring that products are being applied correctly and that quality is maintained.

Their remit is to develop better products that respect the environment and support the industry “Through our site presence, we offer clients an additional layer of security and assurance,” Geoffrey comments. “Product amounts need to be blended and mixed perfectly or they may fail, so our technical advisors ensure that this is done right, every time. Some of our clients are delighted with the service while others are not keen to have us on site. In this case, we’ve introduced monthly training sessions to teach clients about the products, how to mix them and the implications if ratios are incorrect.” The company is placing an emphasis on product

and application training in 2016, along with deeper relationship building and client support. “We must ensure that the right solutions are sold for the right jobs at the right price, and that our clients are satisfied with how the work has gone which is why we always go out to a site and check before we specify our products.

A sustainable future

“Another focus for us is sustainability when it comes to product development and design. The R&D department and laboratory from a technology, innovation and investment perspective are constantly relooking at our products and finding ways to improve them. Their remit is to develop better products that respect the environment and support the industry. “In the same vein, Mapei sees South Africa as a strong investment opportunity and is playing a role in driving our economy and supporting our growth. They can see what the country offers and understand the value of Africa so it is going to be very interesting to see what lies ahead, both for the international and local Mapei brand,” Geoffrey concludes.

Volume and Reach The National Housing Corporation of Tanzania (NHC) is a public body entrusted with the undertaking of a variety of projects in service of the people of Tanzania. Included in this mandate are property management, planning, as well as the construction and provision of houses and other buildings. South African brick- and block-making machinery company, Hydraform International is playing a pivotal role in supporting their work.


ccording to Nazlie Dickson of Hydraform, “The NHC has developed a five-year strategic plan to build and deliver a minimum of 15 000 houses for sale and lease across the country. This directive will be achieved through a spectrum of approaches that include public-private partnerships (PPPs) as well as various alternative building technologies and materials for the construction of quality affordable housing units and homes for low-income earners.”

A prominent advantage is that local raw materials are used to make the bricks and blocks on site, which renders mass scale housing delivery a viable and replicable undertaking Currently, more than 20 of the projects, with units ranging from 50 to 200, are being constructed under the auspices of the NHC in Tanzania using Hydraform technology.

Training on site

“As part of this partnership, we delivered the machines and provided training to the NHC engineers and project managers, who have subsequently reported cost savings of between 15 and 30% using our technology compared with using conventional building methods,” comments Nazlie. “A prominent advantage of the Hydraform system, according to the NHC representatives, is that local raw materials are used to make the bricks and blocks on site, which renders mass scale housing delivery a viable and replicable undertaking.” These projects cover almost 500 houses, and over 20 building sites across the country. While the volume and reach of these projects is vast, they create opportunity for employment as well as learning. “Training people to use our machinery correctly and effectively is an essential part of what we do and rounds off our product offering,” Nazlie concludes.

Big Opportunities Abound “There are a number of factors that contribute to buildings becoming obsolete,” according to Ken Reynolds, Regional Executive in Gauteng for Property Finance at Nedbank Corporate and Investment Banking (NCIB). “These include an increased reliance on IT in the workplace, the same is true for air-conditioning systems which have evolved over the years. Many older buildings are simply not equipped for these needs and therefore lose their appeal and relevance.”


nother trend is the shift from closed to open plan work spaces. “In the past, an average office building would have allocated up to 30m² per staff member. With the move to open plan workspaces, this allocation has reduced significantly to about 10m² per employee. There’s also insufficient common areas and parking spaces. In the industrial building segment, structures that comprise harmful materials and low clearances have become undesirable. It is also increasingly prevalent to separate employees from the potentially harmful materials used in the production processes. In addition, the change in industrial activity from heavy to light engineering, as well as greater demand for warehousing and distribution, has seen a shift in the type of facility that companies require.

Brownfields projects, which involve refurbishing existing buildings, have the advantage of already having all the facilities in place such as water and electricity, as well as approval for services and zoning

Ken Reynolds, Regional Executive in Gauteng for Property Finance at Nedbank Corporate and Investment Banking (NCIB)

In premier locations like Sandton, buildings once considered A Grade that have become functionally obsolete as newer, more advanced structures are built around them, are ripe for development in order to earn a better return. “In a given area, C or D grade buildings still incur the same or higher overhead costs such as rates and taxes, levies and maintenance, as P or A grade structures. As such, in an area like Sandton, where premier spaces have traditionally been in demand and can command a premium, it makes sense for developers or owners to upgrade or redevelop these older buildings.”

Start from scratch

Another question many developers face is whether to renovate or refurbish an existing building, or to rather knock it down and start again.

But Ken says it’s critical for developers and owners, to conduct thorough feasibility studies and market research before deciding what to do with an existing building that has become obsolete.

Know your area

“For example, due to the change in the nature of the demand in Braamfontein, Johannesburg, from commercial to residential, many office buildings in the area have been refurbished into residential accommodation. Another example is in industrial areas such as Isando, where developers are splitting up huge buildings into multiple, smaller spaces to cater for the fact that businesses are requiring less and often different space from their previous requirements.”

“Brownfields projects, which involve refurbishing existing buildings, have the advantage of already having all the facilities in place such as water and electricity, as well as approval for services and zoning,” adds Ken. However, in some cases where the floor area ratio or clearance heights are unsuitable, it may be better to start from scratch. “With this in mind, the biggest mistake developers make is underestimating the problems that they are going to find once redevelopment starts,” he concludes. “Therefore, should the decision be to refurbish a building following a thorough feasibility study, additional contingency costs need to be factored in especially for unforeseen challenges such as elevators that require replacement, massive plumbing, or electrical work that needs to be conducted.” Nedbank, Ken Reynolds

First Dedicated Training Centre The Association of South African Quantity Surveyors (ASAQS) has established its first in-house Training Centre to meet the growing demand for tuition by both qualified members and new entrants to the profession.


he EduTech Training Centre was officially opened in October last year at its operational base, the ASAQS head offices in Thornhill Office Park in Midrand.

Speaking at the function, Larry Feinberg, ASAQS executive director, said, “The new EduTech Training Centre will be able to accommodate 30 students per course, double our previous capacity, in fullyequipped bespoke facilities.

CPD points

“We also intend establishing a special Information Resource Centre at the training centre, with reference material and publications to further help both established and future quantity surveyors with studies or research work.” Karl Trusler, Director of EduTech, which provides both educational and technical support to ASAQS

members, says one of the major priorities of EduTech is to provide training to existing ASAQS members to enable them to earn mandatory Continuing Professional Development (CPD).

Monitoring standards

As there was mounting concern about the varying standards of QS-relevant training provided by other training providers, and no controlling body to monitor standards, EduTech will introduce ‘training-for-trainers’ courses, and also supply tuition on mentoring for companies or QS professionals employing students as part of the Assessment of Professional Competence programme.

Intelligent Design Assa Abloy recently received Environmental Product Declaration (EPD) certificates for its range of concealed Cam-Motion door closers (DC860) and guide rails (G462). Explains Assa Abloy SA’s, Quintin Boukan, “EPDs form the basis for the data for building assessment on an ecological level which is currently laid down in the new European Standard project: Sustainability of buildings.” The declaration also includes details on: Resource consumption and environmental emissions throughout the entire manufacturing process; to what extent a product contributes to the greenhouse effect; the technical properties which are required for assessing the performance of the building products in the building such as durability, heat and sound insulation

or the influence on the quality of the indoor air. The EPD certificate is issued by the German Institute Construction and Environment (IBU), created out of an initiative by manufacturers who decided to support the demand for more sustainability in the construction sector. The closer range optimises the thermal efficiency of the door opening. The intelligent setting adjustment and installation features ensure easy fitment to both heavy and lightweight doors. A modular design and compact size (54mm high x 40mm wide x 40mm deep) and 2kg weight further simplifies planning. The G462 concealed guide rails are integrated with the door frame and perfectly complement the DC860 door closer range. In addition to providing reliable, automatic closing of doors,

the guide rails also electromechanically secure fire and smoke protection barriers. This versatile system allows the DC860 concealed Cam-Motion door closers with different guide rail designs to be used for almost any application. The comprehensive guide rail range enables the required functions to be used in both single-leaf and doubleleaf doors. A coordinator system used in double-leaf door models ensures that the doors are safely closed in the correct order, first the inactive leaf followed by the active leaf and also makes it possible for both leaves to remain permanently open.

While wet concrete might look the same and be delivered in the right consistency, it may have different end characteristics that are completely unsuitable for the job at hand. If corners are cut to save costs and win a tender, it is the end-user who pays the price for poor quality. Fly-by-night operators most commonly substitute quality cement with inferior product, add excessive extenders, use low quality, illegally obtained sand and aggregates or add too much water to the mix to make it easily pourable.

Solar Petals The smartflower is an invention and product of the Austrian business firm, Lisec’s smartflower energy technology and is the first all-in-one autonomous energy source in the world. In the morning, the smartflower orients its large 18m² solar module surfaces to the rising sun automatically and immediately begins to generate electric currents. It is fitted with a 2-axis solar tracker, so the ‘petals’ follow the sun over the course of the day.

The capacity of a smartflower is about 3 400 – 6 200kWh per year depending on the region; thus one station generates the entire average power consumption of a household in central Europe. Depending on the product, the generated electric current can either be supplied to a power net or directly stored and used locally. According to the manufacturer, the (storage) system reaches a degree of private use of up to 100 % (for com-

parison: a rooftop installation attains an average of only 30 %) and holds the power supply steadier than with a static rooftop installation. Smartflowers are intended for private households, but also for communes, shopping centres, companies and hotels. Each smartflower consists of twelve petals. At first glance, one such petal does not appear to be anything spectacular. But Andreas Winter, MD of Glass Forum (the glass-processing branch of the Lisec Group) elaborates, “Each petal is 2.1 metres long and has a diameter of 1.2 metres. The petals consist of two millimeters thin white glass. Each piece of glass is given a C-cut, after which it is tempered. This combination is exactly why this production technology is unparalleled.” Lisec currently produces about 1 200 such glass petals in the Glass Forum every year. Lisec,

Large construction projects such as Wilge have hundreds of workers operating high above ground on the building structures, which they gain access to via numerous means including; cranes, cherry pickers, lifts and scaffolding. As a result, there is always the inherent risk of a fall or entrapment. Skyriders marketing manager Mike Zinn indicates that highly-skilled and experienced Skyriders team of four

A roof overhang over the north-facing windows of the I-CAT office block shades the building during summer and partially during winter

Sustainable Campus Pretoria building contractors, J.C. van der Linde & Venter Projects, has completed a multi-million rand contract for the construction of new ‘green’ corporate offices and a warehouse for I-CAT Environmental Solutions. The new sustainable I-CAT campus, in the N4 Gateway Park in Pretoria, was designed by Earthworld Architects and Interiors. The architects concentrated on maximum sustainability in the design of the campus. For example: a rainwater harvesting system, incorporating a 50 000 litres reservoir, sunk beneath part of the structural pergola-covered courtyard outside the main building. The reservoir will collect all the rainwater from the combined roof area, which covers almost 1 500 square metres. This water will be filtered and reused to flush toilets and for landscaping purposes.

Water and glass processing go hand-inhand and therefore, measures should be put in place to help better utilise water when it comes to polishing, beveling and drilling of glass. For this reason, Bohle Glass Equipment (Pty) Ltd has introduced a range of sedimentation devices designed specifically to not just save water and the environment, but also to save on costs by eliminating the need to replace the water in the machinery tanks weekly.


Architect & Specificator

The contractors had to install solar water heaters that convert solar radiation into thermal energy, and solar powered heat pumps as part of Earthworld’s focus on sustainability. Earthworld Architects and Interiors’ Rudie Botha says, “In summer, the building is ventilated nocturnally and during the early hours of the morning, which allows the temperature inside to drop. When heat builds up inside later in the day, the windows at the top of the building automatically open to allow hot built-up air to escape. Interior temperature is furthermore controlled by an automatic air conditioning system, driven by solar power. “On the north-facing windows, a roof overhang shades the building completely during summer and partially during winter. Vertical fins on the east-facing windows deflect early morning radiation during the summer and the afternoon sun on south facing windows. The use of

windows on the facebrick façade, which faces east and west, was restricted: also for thermal reasons. “The new I-CAT campus incorporates a solar photovoltaic system on the roof of the office building to generate electricity, making the complex largely independent of the national electricity grid.” Pieter Venter, J.C. van der Linde & Venter Projects Tel: (012) 803-0392,

Productivity and wellbeing Redefine Properties’ “green over” of The Towers, nearing completion in Cape Town’s CBD has significantly improved energy efficiency at this property. The Towers, formerly known as the Standard Bank Centre, is likely to get an initial 3-Star Green Star SA rating from the Green Building Council of SA on completion when it is certified. In terms of the existing building rating tool, further annual assessments will follow which will allow asset management to improve the rating further as time proceeds. Daryl Sher, development manager of Redefine Properties, says it has been challenging to make changes to an existing building that would have only managed to get a 1-star rating for energy efficiency, while it was still occupied by tenants. The Towers has remained operational throughout the upgrade, and forms part of the Green Star SA Existing Building Performance pilot programme. The refurbishment of The Towers includes a new flushed glazed system on its external facades that will reduce cooling demand by approximately 30%. Redefine is also investigating the installation of photovoltaic solar panels on the tower roofs, to save energy. The common areas of the building have been fitted with energy-efficient lighting using timer controls and the lights in these areas will be automatically switched off when not in use. Daryl says green buildings are more attractive to tenants and investors because of their triple-bottom line commitments to building efficiency, social sustainability and environmental sustainability. “Businesses are looking for buildings that will complement

The South African branch of Easigrass forms a unique brand within Durban-based Van Dyck Carpets’ portfolio. Commenting on the decision to use Easigrass, Zimbali’s Evan Harrington, says: “We wanted to investigate the use of artificial grass due to the difficulties our landscaping team was experiencing in getting grass to grow lushly within

the shaded areas surrounding our main swimming pool. Mehran Zarrebini, head of Easigrass SA, said they are seeing more hotels and upmarket estates opting for Easigrass over lawn, particularly in the common areas such as pools and children’s play areas. “There are infinite cost-saving benefits because the grass does not need to be cut or tended to in any way. Common areas at hotels and estates are used often, and lawn tends to get worn away

quickly, whereas Easigrass will retain its fresh look for years.” In addition to Fairmont Zimbali, Easigrass Durban has installed the product at a number of high-profile hotels and resorts including; Elangeni Hotel (poolside area landscaped), Umhlanga Sands Hotel and Cabana Beach Hotel (multi-sports’ court areas) and the Oysterbox (outdoor massage cabanas).

After the Wining and Dining While there are still some responsible players in the window and door market, a recent influx of new manufacturers has resulted in compromised quality in favour of lower prices, warns MD and founder of Origin Aluminium, Grant Kalil. “There is unfortunately a trend in South Africa to take the market leaders’ products in any industry, jump on a plane to China and buy from whoever can copy it at the cheapest price. What our local industry does not realise, is that the Chinese manufacturers are masters in these negotiations and once the wining and dining is done, it’s often the consumer who suffers. When the 3rd or 4th container lands, the wall thickness of the aluminium has been reduced to as low as 0.8mm, unbeknown to the SA manufacturer. This reduction in effect halves the strength of the product that has a test certificate to verify the safety of the product. Origin’s suppliers, both local and

For example in China they produced ten 3D printed buildings in 24 hours. Other areas of technology such as BIM (Building Information Modelling) in particular can facilitate greater use of 3D printing in construction.

The aluminium foil or white laminate is glued to the fibreglass base using a specially produced water-based adhesive, ensuring no solvent fumes are released.

“At the heart of BIM is a CAD-driven, 3D design model that enables you to visualise assets in three dimensions. Many working in construction see BIM as a way to deliver projects faster and at a lower cost; similar expectations to those connected with 3D printing. As with 3D printing, the crucial thing here is to demonstrate the capabilities of BIM to encourage the construction sector’s uptake of the technology.”

Ferdie Nell

A Russian in Namibia When a Russian billionaire with a passion for nature and wildlife recently purchased almost 30 000ha of land in Namibia, it resulted in the construction of the luxury Marula Game Ranch. RBL Architects specified several of Sika’s high performance waterproofing products for the lodge’s one million-litre swimming pool. NMC Construction Namibia was awarded the contract to apply Sika Waterbars, SikaSwell S-2, SikaPrimer-3N and Sikasil-Pool. The waterproofing process commenced with the application of SikaSwell S-2 to the 60m of construction joints on the floor of the pool. Sika Waterbar Type O-20 was used as a centrally-placed waterbar in all the expansion joints. Manufactured from virgin thermoplastic PVC for easy,

on-site welding, internationally-tested Sika-Waterbars are used to seal construction and expansion joints in all water retaining structures. Sika Waterbar Type DR-20 was placed in the external wall joints of the pool while the 135m pool perimeter, between the wall and floor, was sealed with SikaSwell S-2. All expansion joints were subsequently primed with SikaPrimer-3N, a one component, epoxypolyurethane solvent-based primer for porous substrates. To complete the waterproofing process, Sikasil-Pool, a one-part, neutral curing silicone sealant especially designed for swimming pools and any permanently wet areas, was applied to the joints.

retrofitted building in the country to receive a 6-star GBCSA rating, a benchmark in sustainability and green building design.

Cobra Watertech’s commitment to the preservation of the country’s natural resources through the design and installation of water- and energy-saving tap and plumbingware ensured it played a vital role in the recent refurbishment of WWF South Africa’s Braamfontein office, which received a 6-star Green Star rating from the Green Building Council of South Africa (GBCSA). WWF-SA considers its refurbished building in Braamfontein, also the first

“We did not build our new office, we reconstructed it. We re-used and recycled everything that we could possibly salvage from this old structure. The WWF Braamfontein building ultimately disproves the notion that green buildings are expensive,” says Dr Morné du Plessis, CEO of WWF South Africa. As part of the refurbishment, the kitchen, bathrooms and restroom for people with disabilities were overhauled. Products from Cobra’s Capstan and medical ranges were specified for these rooms including metering taps and spouts; stoptaps; sink mixers; a shower arm and pulsating shower rose; and bottle trap.
