Celebrating a triumphant year! 2009 was an interesting year for many a company, Media in Africa included. Companies that have modernised their businesses and understood that this is a time of growing and adapted to the climate, will reap the benefits of surviving the growing pains. Our business was blessed with brand new clients, record invoiced bumper issues, exclusive subject matter and boasts a brand new design. We engaged our readers with world-class content including interviews with world leading architects and prominent figures in the built environment such as Daniel Libeskind (featured in this issue again), Tokyo Sexwale and Mark Pencham (who can proudly lay claim to the DIRCO facility in Pretoria), amongst others. You can rest assured in the fact that we deliver a world-class product every issue! The financial crisis has certainly put many things in perspective and changed consumer behaviour worldwide. Simplicity, recycling, and rustic living have become the flavour de jour in 2009 and this trend will likely continue in 2010. Natural and organic has translated into fashion, food and a way of life. An appreciation of the simple things has not only become an escape from the day to day madness, but holistically and in our subconscious, is paramount to our survival. With this comes a more optimistic view of what lies ahead in 2010 and I feel the excitement of this year brewing everywhere I go. After a much needed rest for all, 2010 will see South Africa venture into a new way of conducting business due to the estimated 400 000 international and African visitors that will put an enormous strain on our current infrastructure. What an exciting opportunity! Ladies and gentleman, let the games begin!

Faster, more versatile
cladding solutions
Upat SA (Pty) Ltd has introduced fischer Fixings’ Advanced Curtain Wall Technique (ACT) to South Africa. This system offers architects, engineers and specifiers an innovative and high-quality system for the fixing of ventilated cladding. The first fischer Undercut Diamond drill rig in Africa has been in operation since September. It was commissioned and installed by Upat SA and it promises to give Fisher ACT clients a faster, more versatile concept when it comes to cladding projects. For façade applications, fischer ACT prescribes the use of ceramic tiles from 10 mm thickness and natural stone panels from 20 mm in thickness. The fischer ACT system allows free positioning of the anchor anywhere on the rear side of the panel, as well as easy placement and replacement of all or individual panels (even soffit panels). Much higher loads are achieved compared to traditional systems, due to the stress-free fixing technology applied in the panels and the anchor positioning that is optimised, providing approximately 50% less bending
within the panel. The aesthetic highlight of ACT’s system is its undercut technology, combined with the FZP anchor range, which ensures that there are no visible fixing elements at joints. The fischer ACT system also provides an environmentally beneficial solution for both new and refurbished products. This system can accommodate thermal and acoustic insulation, moisture and weather protection which results in energy saving in the long term. The technical, financial, aesthetic and environmental advantages of the ACT system, coupled with Upat SA’s strong distribution network, local and international partners, put Upat SA in the ideal position to supply the demand that the fischer ACT System is expected to generate.

Reduce costs with new Dulux Trade’s WEATHERSHIELD paint is specifically designed to take the anguish of paint choice out of the equation when contractors need to choose paint. This smooth exterior paint represents a breakthrough in the exterior paint market, due to its advanced spreading rate of up to 14 m2/l so that more surface gets covered with far less paint, saving both time and money. Dulux Trade R&D executive Tony Pillay, who headed the team that originally formulated this remarkable paint, says that the paint’s in-can structure is what makes it so different from a trade point of view. “The nature of the viscosity or rheology of the paint is that it appears very thick in the can, but the structure has been engineered to allow contractors to load the paint directly from the can, and still the paint spreads like butter when rolled onto a wall. It has superior adhesion to cement-based surfaces and offers the best smooth coating on the market in a two-coat application,” says Pillay. An added bonus is that, while Dulux Trade WEATHERSHIELD delivers lasting quality protection, its excellent sustainability properties and low VOC levels radically reduce any harmful impacts on the environment. Xavier Rijmenans, ICI Dulux Head of Trade Marketing, explains that a person’s choice in paint can have serious implications on the
environment-conscious paint environment. “Huge strides in technology have enabled environmentconscious paint manufacturers to develop ‘greener’ paints, which means today there is no need to have a paint that visually enhances the appearance of a building but impacts negatively on the environment,” says Rijmenans. As a founding member of the Green Building Council of South Africa, Dulux Trade’s commitment to sustainability is genuine and long-standing. Dulux Trade plays a key role in encouraging this country’s construction industry to adopt a greener approach to its buildings. Dulux Trade WEATHERSHIELD is also available in 84 trendy exterior colours, allowing for great flexibility and originality in design. As its name suggests, Dulux Trade WEATHERSHIELD is a premium-quality product that offers an outstanding solution to exterior painting requirements in harsh South African weather conditions.

Practical guide for green retrofitting of buildings The Green Building Council of South Africa (GBCSA), together with international engineering and consulting group Arup, has published a new publication aimed at property owners, managers and consultants who are looking to upgrade and improve their existing building stock. “Existing Buildings Survival Strategies”, which is based on a similar initiative by the Property Council of Australia and Arup Australia, is a practical, user-friendly, step-by-step guide on the process of retrofitting existing buildings to become greener and more efficient. This publication has a major focus on energy efficiency (it has been supported by Eskom), yet it is set to appeal to everyone who wants to maximise value by refreshing building stock which is no longer performing in line with market expectations. This booklet takes local and international case studies and breaks down the six main stages of a retrofit: Stage 1: Determine your baseline Stage 2: Review your building maintenance and operational issues Stage 3: Establish your targets and goals Stage 4: Decide on an appropriate level of refurbishment Stage 5: Select your optimal upgrade initiatives Stage 6: Make your survival strategy happen The publication also includes a particularly useful section that lists two hundred optimal upgrade initiatives, categorised into sections such as management, energy-lighting, electrical and HVAC, materials, waste, water and more. “This is the ideal reference for all those wanting to improve the efficiency and environmental sustainability of their buildings, but who are wondering where to start,” explains Nicola Douglas, CEO of the GBCSA. “We’ve been inundated with requests from property owners and managers for assistance in greening their current buildings, and we’re very excited to be able to offer this resource as a starting point.” According to Arup staff who researched and wrote the guide for the Southern African region, “increasing the useful lifespan, commercial and visual value of existing buildings will not only benefit owners and users; but will act as a catalyst to rejuvenate decaying and unsafe urban environments to the benefit of all community stakeholders.”
Copies of the “Existing Buildings Survival Strategies” guide can be purchased on GBCSA’s website at www.gbcsa.org.za. The GBCSA is planning to launch a series of retrofitting training courses for early 2010, which will be based on the publication.

High-efficacy corrosion inhibitor A study by the American University of Sharjah in United Arab Emirates has singled out BASF’s Rheocrete 222+, a state-of-the-art admixture designed to inhibit the corrosion of steel reinforcement in concrete, as the most effective among common commercially available alternatives. The study, conducted in the second half of 2008, evaluates the effect of three different corrosion inhibitors – a calcium nitrite inhibitor (CNI), a migratory corrosion inhibitor (MCI) and BASF’s Rheocrete 222+. The findings were based on the rate of corrosion in reinforced concrete beams containing these solutions. Accordingly, the rebars in the beam containing Rheocrete 222+ showed the lowest rate of corrosion and the lowest mass loss. Reinforced concrete is used extensively as a construction material. However, corrosion of the steel bars used for reinforcement can occur in the presence of water, oxygen and chloride ions, compromising the integrity of structures and leading to premature failure. While there are

Number 1, 2010
established methods of protection, such as cathodic protection, coatings, addition of inhibitors to the concrete, or a combination of these methods, there are several advantages to using corrosion-inhibiting admixtures. Not only are they easy to dose into the mix and give uniform protection to all steel in the structure, but also quality control is simple compared to other methods (e.g., application of coatings) and no maintenance is required.

“creates architecture”at Cersaie 2009 Renzo Piano’s conference at Cersaie 2009, entitled “Creating architecture”, attracted so many people that the organisers of Cersaie had to refuse admission. A huge number of international journalists attended the press conference preceding the keynote address at 11:00 am and the entire capacity of the Palazzo dei Congressi was filled during the event. All the rooms in the building were used and Renzo Piano’s conference was screened on closed-circuit television in the Architecture Gallery and the Press Office in the exhibition centre. The organisers of Cersaie regretted being unable to accommodate everyone who wanted to attend the event and they have made photos from the event available on their site, www.cersaie.it. Architects are adventurers, says Piano During Renzo Piano’s conference, this famous Genoese architect told the audience that architecture is the profession of an “adventurer”. It is a dangerous profession for those who undertake it but one that offers the opportunity to come into contact with different worlds, people and situations. Continued on page 16

According to Piano, architecture is a profession of art and adventure on various levels: technological, humanistic – because buildings are designed and built for human beings – and the more poetic and imaginative level. When responding to both practical needs, expectations and desires, architecture becomes something extraordinary because buildings not only meet technical and technological criteria, but also celebrates aspirations and desires. Piano displayed images of his various works over the years while he explained his ideas of architecture and how they merge with his vision of life. “My father was a builder so I grew up on his building sites, and the miracle of building is something that stays with you,” said Piano. “These are my roots,” he continued, before stressing the importance of listening. According to Piano, a continuous dialogue is essential, not only with the people involved in the various projects but also with other fields of art and design. One needs to be able to learn from the abilities of others and from other fields of knowledge and expertise. For Piano, artisan skill and science have the same value. Creating architecture also means understanding that all creative effort must improve, transform and describe the world through tools and practical solutions. One of the examples that Piano used was the creation of work from the observation of places and nature – to discover how certain geographies and given topographies or existing materials contain the seeds of clearly defined architectural characteristics. Observing reality and curiosity towards human beings are fundamental qualities of architects. Piano told the audience how he feels the city is the venue for exchange and creative stimuli, the place where everything happens.

Number 1, 2010
The city expresses the idea of openness and tolerance, two qualities that derive from Piano’s life experience. “I graduated just before 1968, a time of great yearning,” he said. This sentiment is reflected in his idea of architecture and in works like the Beaubourg, a place that became an accessible place (a factory) after open dispute with those who wanted it to be a cultural centre that would intimidate potential users. According to Piano, the museum that forms part of Beaubourg, Musée National d'Art Moderne, merges the sacred and profane. Beaubourg is transformed into a part of the city, making it like a collector’s piece. Architecture is creation, art and above all the capacity to transform the world and create languages, starting out from contingent needs. An example of this in today’s world is the realisation that “the Earth is fragile” and how buildings should be constructed with this fact in mind. We need to identify and use materials that respect the environmental balance. Piano stressed that one of these materials is ceramic. “It is ancient, it comes from the earth and returns to the earth, but above all it has characteristics of strength, durability, unlimited colour potential and the capacity to reflect light, making it functionally perfect and extraordinary in various situations,” said Piano. To illustrate this point, Piano referred to the headquarters of the New York Times. White ceramic elements were used to make optimal use of light and the sun’s rays for this building. Piano feels that the challenge is to create buildings that are less “violent” (in terms of energy requirements) and can achieve economies in the use of sources, while not losing contact with human beings and their requirements. In this regard, the architect is part anthropologist, part scientist and part adventurer.

Towards the end of the conference, Piano explained how the construction of a building is like “crossing the Far West�: although dangers and unforeseen situations may lie just around the corner, the rewards are worth the challenges you have to face if the final result not only creates something useful but has the ability to change the world.

Luke Meyer The spheroid shape of the GLA occupies 25% less space than a cube of the same volume.
Green building innovation: the London Mayor’s office
City Hall has no front or back side – it is a glass spheroid and it is designed to minimize the surface area that is exposed to direct sunlight. The building comprises of committee rooms, public facilities, a meeting chamber, an office for the Mayor of London and GLA staff. The architects were required to provide 54 cellular offices, with the rest of the space being open-plan.
www.eyefetch.com
The GLA provides natural shading from the most intense sunlight.
Foster and Partners, one of Britain’s leading architect firms, received the brief to design City Hall, a building for the Greater London Authority (GLA), that would be seen as a new landmark for London. The building, which is located on the
City Hall’s spheroid shape The spheroid shape of the building, which was generated as a result of scientific analysis, allows it to occupy approximately 25% less surface space than a cube of the same volume. The goal of the sphere shape is to reduce heat loss as well as solar gain through the building’s skin. The shape and the alignment of the building, coupled with the use of passive environmental control systems, enables City Hall to maximise its energy efficiency due to the fact that it can run on a quarter of the energy that a typical high-specification building would need. Maximising energy efficiency The building leans back towards the south, providing natural shading from the most intense direct sunlight. Energy is saved by the recycling of heat that gets generated by lights and computers and the building is also naturally ventilated by windows in each office. Electrical consumption is further reduced by the use of cold groundwater to air-condition the building. This groundwater is extracted from the water table beneath London through two boreholes and this water is used to firstly air-condition City Hall and then used in toilets to save water. In 2007, photovoltaic solar panels were installed on the roof to provide solar power to the building. This solar power project was funded and implemented by the London Climate Change Agency.

City Hall – some key facts Height of the building: 45 m No. of floors: 10 floors above the ground Gross floor area: Approximately 18 000 m2 Nett lettable floor area: Approximately 12 000 m2 Steelwork: Structural frame – 2 100 tons, Reinforced – 1 950 tons Concrete (core): 13 100 m2 Cladding: 7 300 m2 of triple-glazed, low-emissivity coated clear glass, incorporating shading devices Heat insulation: Average value = 0,7-0,8 W/m_.k Angle of glass front inclination: 31° Diameter of circular glass facade: 45 m Environmental strategy: Windows open for natural ventilation, borehole water cooling, heat recovery, displacement ventilation system Energy consumption: Energy consumption for GLA's environmental systems is less than half levels in DETR good practice office guide. The radical shape of the building minimses the surface area (approx 25% less than an equivalent rectangular building). City Hall is also self-shading and the high-performance façade ensures excellent energy efficiency. Electrical consumption: Greatly reduced due to the use of cold ground water instead of refrigeration to air condition the building. Saving use of mains water, the water is extracted through two bore holes from the water table beneath London and is used to cool the building and is then used for flushing the toilets.

How the building was chosen A competition that combined the best site with a design competition was used to choose the City Hall building. Fifty five potential buildings and sites were submitted and seven of these initial ideas were put forward for public display at the Oxo Tower Wharf in September 1998. Visitors were invited to complete a questionnaire to voice their views on the seven submissions and the results showed that Victoria House and More London Bridge were the most popular. These two front runners were further developed and, in February 1999, former London Minister Nick Raynsford announced that the Government would be moving forward with the London Bridge City scheme, now known as ‘More London’. The Government Office for London (GOL) struck a deal with the CIT group of developers after City Hall proved to be the most popular with the general public and, as a result, the Greater London Authority secured a 25-year lease on City Hall. The Greater London Authority paid an annual rent of £393 per m2 (this was frozen until 2007). Developers expect that the total construction costs for City Hall and related infrastructure amounted to £65 m.

Cersaie 2009:
Design, ideas and ceramic creativity The 27th edition of Cersaie was held in Bologna, Italy, from the 29th of September to the 3rd of October 2009. Over a thousand companies from 34 countries came to display their latest innovations, trends and concepts in the bathroom furnishing and architectural ceramics sectors.

Exhibition space at Cersaie 2009 was sold out and the overall figures confirmed the international importance of this event for exhibitors and visitors alike. 510 exhibitors were from the ceramic tile sector, 380 from the bathroom furnishing sector and a grand total of 83 137 visited this landmark event. Innovative modular solutions Italian ceramic tiles never cease to amaze when it comes to the industry’s ongoing search for different sizes, styles and colours, textures and finishes. We’ve seen elegant finishes that recreate the magic of wood and the allure of mosaic, precious metals such as gold and platinum, gemstones like amethyst, glossy and matt glazed finishes that capture and reflect light with surprising sheens; all produced in a wide range of colours and sizes, from the most traditional to the most innovative modular solutions. The ancient art of ceramics is continually renewed to become a modern furnishing solution by exploring volumes, colours and surfaces that complement contemporary living solutions. New trends in architecture are enhanced by the use of ceramic tiles, which are increasingly being selected early in the design stage as capable of creating furnishing elements and atmospheres with appealing design, optimising available light and enhancing volumes with plays of perspective. Tiles that don’t look like tiles Latest-generation technologies now allow for the production of large-format tiles that bear more resemblance to a “sheet” of material than a “tile”. Tiles are being produced in ever smaller thicknesses, thereby combining highperformance with a focus on sustainable development. Continued on page 22

In amongst this kaleidoscope, we also find the warm tones of precious metals, pure black and white as well as the reds, greens, blues and silver finishes to create ever-new and original colour solutions capable of enhancing materials and stylistic solutions. Lend character to your space Trend-setting and creativity in the ceramic tile industry have given rise to tiles that incorporate timeless elegance into residential, commercial and office spaces, both public and private. Plenty of the collections from Italian ceramic tile producers are inspired by fabric prints, with textures resembling lace or featuring geometric and floral patterns, as well as modern and abstract screen-printed designs that create surfaces with myriad hues that lend character to any interior or exterior space, whether residential or commercial. With materials ranging from porcelain to single- or double-fired tile through to clinker and terracotta, ceramic can reproduce the austere and timeless elegance of natural stone and wood but revisited in a modern vein, as well as nylon, carbon fibre and Gore-Tex; it can create collections inspired by the hi-tech objects that are currently in vogue. Latest-generation Italian ceramic tiles have that extra ingredient to make everything appear more glamorous, fresh and new, whether they are used in sitting rooms, bedrooms, bathrooms, kitchens or gardens, offices or other workplaces, shopping centres or stores, places of worship or cultural spaces, places of entertainment or eateries. Their combinations of styles and trends enable designers to create elegant, sophisticated and functional living solutions that can harmoniously fit into the surrounding environment.

What the experts are saying A conference entitled “Ceramic tile, star of habitats. New trends in design” was held on the 29th of September to discuss where innovations in the ceramic materials industry are heading. During this discussion, Alfonso Panzani, Chairman of the Ceramiche Ricchetti Group, explored the current state and future prospects of the relationship between ceramic materials and architecture, between design and figurative culture, as well as the development of aesthetic tastes and the ability of technologies to respond to demand. Florence-based trend-setting expert Orazio Lo Presti discussed “Cool gestures and actions”, starting out from the increasing interplay between the various forms of expression. Lo Presti argued that developments in art, design and fashion have generated new needs in terms of aesthetic and technological research and he believes the ceramic sector must evolve continuously in order to satisfy requirements of quality as well as choice of products.

Veronica Dal Buono, Researcher at the Faculty of Architecture of Ferrara, discussed the topic of “Ceramic: an expressive material that combines technology, language and communication”. Ceramic materials have been transformed from an everyday surface-covering element into a complex article, an advanced component of building systems that combines aesthetic/functional values with constantly renewed decorative aspects, material research and technological properties thanks to innovations in the industry. Ceramic is a “designed material” and a technological product that is of interest to both the market and to architectural production due to its combinatory flexibility, reproducibility and sustainable productivity, as well as the intrinsic value of the material. In designer Glauco Gresleri’s talk, entitled “From matter to material”, he spoke about architects’ continued use of ceramic materials in a traditional way as finishing products such as wall and floor coverings, in spite of the constant development of tiles in terms of technological and stylistic innovation. As in the case of cement which has evolved from a binding material to take on its own specific expressive qualities, new uses and new forms, architects can now also launch ceramic materials towards the widest range of uses, such as new building and furnishing components. Chair Baglione, who is an architect and architecture historian, posed the question “Ceramic: only a covering material?” Baglione showed how ceramic has been used in the works of some of the key figures in twentieth century architecture – from the Catalan Modernists to the Viennese Secessionists, from Perret and Berlage through to the masters of Italian modern architecture such as Gio Ponti – for highly sophisticated applications reflecting the complex relationship between decoration, ornament and values of the building. The development of the sector and the increase potential uses of ceramic has showed how useful it is to reflect on the expressive potential of this material through a comparison between works of contemporary architecture and historic examples in search of a “continuity” that is proving increasingly essential for authentic innovation.

Choosing a
ceramic covering for your façades According to Gail.com, there are two main things to consider when choosing a ceramic covering for your façades: aesthetic detail and technical performance. Your ceramic cover needs to be able to resist pollution, bad weather conditions and discoloration from the sun. Ideally, the covering should also be easy to maintain. The water absorption rate of ceramic tiles, which reflects the density of the body of the tile, is one of the factors used to classify ceramic tiles. In South Africa, the coverings of façades should have a water absorption rate of less than 6% (in colder regions that are subjected to temperatures below 0°C, the water absorption rate should be lower than 3% to provide a better resistance to freezing). It is common for ceramic wall tiles to have a glazed or matte surface, which is normally less durable than floor tiles (Mohawkflooring.com). These semi-gloss and glazed tiles have a low slip resistance, which make them ideal for walls and countertops. Sources: www.gail.com.br; www.mohawkflooring.com

Thin-bed tile adhesives reduce cement use by
70%
Wacker Polymers has recently revealed a study that shows how modern thin-bed tile application techniques using ceramic tile adhesives with VINNAPAS® polymer additives can reduce the use of cement in tile applications by an astounding 70%. Wacker Polymers undertook comparative studies on a tiled house of 65 m2 to illustrate this appealing statistic.
The ceramic tile adhesive is 10 mm thick and weighs approximately 10 kg per m2 in traditional thick-bed applications. The new thin bed technique is able to reduce the ceramic tile adhesive thickness to 4,5 mm, bringing the weight per m2 down to a mere 3 kg. These reductions add up to a total mortar saving of 455 kg over the entire house. The actual savings of using these techniques would be even greater than the comparative study shows, due to the fact that the study was based on conservative data. Normally, the thickness of traditional tiling mortar is 20 mm-30 mm, while the thickness of a thin-bed tile adhesive is 2 mm-4 mm. “Thin-bed mortars also offer significant advantages, in terms of less material usage, reduced application time, and safer and more durable installations of consistently higher quality,” says Dimitrios Moussios, Marketing and Business Development Manager of Wacker Chemicals Middle East. “All of this adds up to better construction, with reduced labour and material costs, thereby affording artisans the possibility of better margins while still making it possible to pass significant cost savings on to the customer. This means that artisans using thin-bed techniques and products containing VINNAPAS® polymer additives have a significant competitive advantage.” Using tile adhesive that contains these polymer additives provides good workability, particularly in the fresh mortar stages, making it easy to apply and press the tile into the adhesive, with good wetting power, long open time to adjust the tile position, good anti-sagging properties and good water retention for full hydration of the cement. VINNAPAS® also offers good adhesion on a wide range of substrates in hardened mortar, including concrete, plaster, wood, old tiles, PVC; good tensile adhesion strength after any storage conditions and high deformability, even under extreme climatic conditions.
Specialists in metal finishes
Product test in the Burghausen applications lab: a lab technician checks the adhesion and processing properties of special tile adhesives that are modified with dispersible polymer powders. For critical applications such as tile-on-tile bonding, the adhesives are fine-tuned to the tiles and substrate by modification with VINNAPAS®.
Dimitrios Moussios, Marketing & Business Development manager from Wacker Middle East, demonstrates the deformation behaviour and sheer force between tiles and substrates for flexible and rigid tile adhesives, and how VINNAPAS® contributes toward the long-term durability, functionality of the mortar.

Multipurpose primer for walls and surfaces A.Shak, a leading building industry chemical manufacturer in South Africa, has introduced two innovative and highly effective products to the market. Bonding ceramic tiles to smooth surfaces and transforming outdated tiles and melamine cupboards with paint is now simple and easy. Bonding ceramic tiles to concrete, vinyl and existing tiles TILELOC is a water-resistant additive to assist the bonding of ceramic tiles to smooth surfaces. This product was designed specifically to use on smooth surfaces such as off shutter concrete, power-floated floors, existing ceramic tiles and vinyl and it can be used as an additive to waterproof screeds as well as a bonding agent where a very thin screed is required. This additive can be used when re-plastering over an enamel paint surface or added to cement-based tile adhesives or grouts where waterproofing is essential, for example in a shower cubicle or where dampness is expected. Application to smooth surfaces A scratch coat needs to be applied when bonding to smooth surfaces. Two-thirds of this scratch coat consists of river sand, one third consists of cement and sufficient TILELOC to make a loose mixture. When applying the scratch coat to the surface, a block brush should be used. Wait for the scratch coat to become tacky before applying the tiles or screed (bonding will be better on rougher surfaces). *Note: If TILELOC is added to tile grouting, the surface must be cleaned thoroughly before the grout sets. TILELOC should not be added to white grout as it will form a yellowish colour.
Paint over ceramic tiles with TILEPRIME – compatible with PVA and enamel.
Use TILEOC to bond ceramic tiles to smooth surfaces.
Transform your walls and surfaces TILEPRIME allows you to transform outdated ceramic tiles and melamine cupboards with paint. This multipurpose primer for ceramic wall tiles and melamine surfaces is compatible with both PVA and enamel paints and it does not contain solvents, ensuring there are no strong or unpleasant odours during or after application. Applying the primer Ensure that the surface is clean and dry. The surface to be primed should be free of all dirt, grease and mould. Chips and defects in the surface should be filled with the appropriate filler before priming. TILEPRIME is applied by either brush or roller and it should be left for 24 hours before painting. If enamel paint is used, the solvent in the paint will temporarily soften the TILEPRIME – be careful not to damage the painted surface until it has re-hardened. Wash brushes and rollers with water. *Note: The painting of kitchen worktops is not recommended. A.SHAK Tel: 011 822 2320 E-mail: sales@ashak.co.za Website: www.ashak.co.za

Redefining in South Africa
International fashions in sanitaryware, baths and tiles.
Lighting specialists designed lighting for each product on display.
Italtile recently launched a showroom concept that radically redefines bathroom showrooms and display in South Africa. “The Italtile Pretoria showroom extension came about as a result of investigation into the premium tile and sanitaryware market in South Africa,” explains Sergio Galli, one of the Directors of Italtile Retail (Pty) Ltd. He believes the current model is one-dimensional and focused on either tiles or sanitaryware, with ineffectual and limited choice in terms of a complete bathroom solution. Italtile has capitalised on this opportunity with the launch of a unique 1 000 m2 Bath-Shop, extending the Pretoria showroom to a massive 2 100 m2. With complete bathroom solutions under one roof, it enhances the specifier’s shopping experience by opening up a whole new dimension of choice. The space has created a unique environment that brings together the latest showroom display trends and international fashions in sanitaryware, baths, tiles, taps and bathroom accessories. The showroom design emulates the main building structure by making use of a circular platform with multi-level walls that allows for ease of movement around the showroom, at the same time creating an axis for the display area. Each range is tastefully styled for visual enhancement, as well as design, product and layout inspiration for prospective clients. With such an array and assortment of product on display, lighting for the entire showroom plays a critical role. Lighting designers and lighting specialists designed lighting not only for each product and each display, but also to showcase the space and create the right ambience. Sergio Galli comments further on their investment and commitment: “Italtile is committed to remaining at the forefront of product styling, fashions and trends, thus proving that, as the longest-standing retailer in this market, we are best suited to meet the customers’ needs. And with an investment and commitment of this nature, we can reassure our customers that we will remain a beacon of trust and consistency while many competitors have come and gone.” Italtile has also launched a less expensive range that still includes all the cutting-edge features that customers want from their tiles, while also fitting a wider range of pockets.

Locally produced tiles that exceed international standards.
Wise tiling specification key to success Using tiles as cladding is a very popular way to change and enhance the look of new and existing walls, both interior and exterior, as they not only provide a hard wearing, long lasting and low maintenance finish, but they can also provide a diverse range of aesthetic finishes by laying tiles in different patterns, using different tiles, or using panels of tiles and different materials such as textured wall coatings. Glazed ceramic and porcelain tiles in a wide range of colours and textures.
Johnson Tiles, a division of Norcros SA, remains at the forefront of introducing cutting-edge technology in order to produce tiles of an international standard here on local shores. Outstanding compliance For the first time, locally produced tiles comply with or exceed both SABS 1440-1996 and the European EN 177 technical standards. Johnson Tiles takes great pride in being the first company in South Africa to locally manufacture both glazed porcelain tiles, and tiles with a PEI 5 rating. Historically, porcelain tiles were imported because the technology and skill did not exist in South Africa until it was developed by Johnson Tiles, hence the company has great pride in this locally developed product. All-important selection When selecting tiles it is important to verify that the tile selected is suitable for the application, preferably against a written supplier’s specification. Factors such as water absorption, irreversible moisture expansion, MOR and PEI ratings, chemical resistance and overall stability of the product need to meet the requirements of the service conditions.

Choosing the incorrect type of tile for the service conditions can be disastrous. Careful consideration must be given to the expected performance of the tile in terms of traffic requirements, resistance to scratching and abrasion, physical strength, and porosity, particularly in external or wet environments. Johnson Tiles glazed ceramic floor tiles are available in 330 x 330 mm, 400 x 400 mm and 500 x 500 mm format, while the glazed porcelain tiles are available in a 400 x 400 mm format. The tiles are deliberately designed to be attractive to a wide segment of the market, suitable for both domestic and commercial applications. Both the glazed ceramic and glazed porcelain tiles are available in a wide range of colours and textures, and can be purchased at selected tile merchants throughout South Africa.

New silicone sealant – the for stains on exterior façades Take a look at buildings in the busy cities of South Africa and you will see obvious stains around joint-sealant perimeters on many prestigious structures. Stains on aluminium composite panels, glass and natural stone are often a result of hydrophobic oils and plasticisers in silicone sealants that tend to run down with rain, streak on non-porous substrates, or get absorbed by capillary absorption on porous substrates. Even though silicone sealants can result in ugly stains around joints, they are still used in exterior façades due to their superior durability properties. Today, Silicone and Technical Products, the distributor of GE sealants for South Africa, is capable of providing you with a non-bleeding, neutral cure silicone sealant, GE SCS9000, to solve aesthetic problems associated with conventional neutral or acetoxy cure silicone sealants.

New year, new goals and a new prognosis for the
building industry
Last year saw the crippling effect of the global recession severely impact the South African building industry. Despite huge developments and projects being built, many companies and firms were hit hard. But we have begun a new year, with new goals, outlooks and forecasts.
Investec.com notes that signs of recovery in the building and construction sector started to emerge towards the end of 2009 and many key indicators show that we are at the turning point, on our way back to heady growth rates. Walls&Roofs takes a look at what this much anticipated year will hold. Commercial public and non-residential building soars Dirk Meyer, Managing Director of Corobrik (Pty) Ltd, gave his prognosis for the building industry in 2010. According to Meyer, the building construction industry has been marked by diminished activity in a number of sectors, most notably the private residential sector. Commercial public, non-residential and private building activity, on the other hand, has been robust, providing many opportunities for industry products. The turning points in our economy In his article, Meyer writes about the South African Chamber of Commerce and Industry’s Business Confidence Index recording a lower turning point in May 2009, which has subsequently recorded 4 months of increasing
040 WALL S & R OOF S
Number 1, 2010
Pr ojects business confidence levels. Similarly, the South African Reserve Bank’s composite leading indicator for the building industry also recorded a lower turning point in May 2009. Omigpi.com reports that things in South Africa have started to improve and South Africa will show positive GDP growth early next year, but it will take some time before we get back to the type of growth rates we saw in 2006 and 2007. According to Meyer, these turning points are pointing to an upturn during the first quarter of 2010, as they anticipate upturns in building activity levels 6-9 months in advance. The SA property market and building industry The prime lending rate has dropped from 15,5% in December 2008 down to 10,5% towards the end of 2009, which Meyer believes may have bolstered the FNB Property Barometer. This barometer surveys a sample of estate agents in the major cities of South Africa to report what type of demand they are experiencing. The FNB Property Barometer of the second quarter of 2009 stated that much of the evidence in the property market shows that the demand for residential property will be a slow and moderate strengthening at best, with much depending on the global economic recovery’s positive impact on the South African economy. This barometer also showed that buy-to-let property buying isn’t yet showing signs of recovery, making up only 11% of total buying in the first and second quarters of 2009. John Loos, Property Strategist at First National Bank, says this doesn’t paint a pretty picture for the building industry, but we have to be patient. “Recovery has been in place since earlier this year (2009). Although some of the figures aren’t looking good, recovery is in process and volumes have been going up,” says Loos. According to Loos, the housing and property aspects covered in the FNB Property Barometer are a prognosis for what the building industry can expect. “The building and construction numbers will improve towards the second half of 2010. We have reached the turning points; we are on our way up. But this also means that there will be a considerable lag before the recovery filters through to the building industry,” says Loos. “The commercial sector of construction is just starting to experience the lag and I anticipate that the commercial side will take even more strain before they go into recovery. Like I said – it looks gloomy now, but things are turning up and we need to be patient.”
Although downscaling due to financial pressure is the foremost reason for selling property (34% of people, from all income brackets quoted financial pressure as their no.1 reason for selling), there are also areas of improvement when it comes to reasons for South Africans to sell their properties. Selling in order to emigrate dropped from a peak of 20% in total sellers in the third quarter of 2008 to 8% by the middle of 2009. Despite the buy-to-let buying not recovering just yet, estate agents report an increase in the number of show days and increased levels of successful sales of existing and new houses. Building activity will continue to rise In his prognosis for the building industry in 2010, Meyer also writes about the anticipated moderate recovery in building activity for 2010 which will sprout from the renewed activity levels in residential developments and from a rise in Public Sector projects. Omigpi.com reports that building completions across office, retail and industrial segments are coming off record highs and that building plans passed are stabilising in all three sectors. According to Meyer, the influx of residential and non-residential projects from the Public Sector following the general elections in April 2009 is starting to materialise. Total building activity is also expected to increase due to a further rise in Public Sector projects that will be awarded in 2010. 2010, the FIFA World Cup and building Although the level of building activity is not expected to recover to the highs experienced in the first half of 2007, Meyer believes that there is a generally positive expected for 2010, continuing into 2011. The major cities of South Africa, which are hosting 2010 FIFA World Cup games, are busy with upgrading their highways, walkways, infrastructure and public spaces. R17,4-billion has been made available to the different provinces for use in construction and revamping stadiums (Mediaclub. com). By 2010, our country will have better public transport, better roads, better sports facilities and more housing developments than we could have imagined 10 years ago. Omigpi.com’s view remains unchanged, namely that even though South Africa wasn’t as severely impacted by the financial crisis (compared to those countries with banking exposure to toxic assets), we have been in the worst recession since the 90s. But things are looking up, turning around and moving forward. Patience and perseverance on behalf of the building industry will start to pay off this year, with many projects, developments and positive foresights guiding the way to a greater South Africa.

Pro j ects Façade Solutions for the Moses Mabhida Stadium in Durban.
Moses Mabhida Stadium’s façade: a technical triumph Newly-built and renovated stadiums in South Africa will play host to an estimated 3,5-million people during the World Cup. Located in KwaZulu-Natal in the beautiful city of Durban, one stadium in particular, the Moses Mabhida Stadium, has enjoyed the expert attention of a team of engineers and specialist contractors for the design and installation of its magnificent façade. Façade Solutions and Linda Ness Associates successfully implemented an innovative façade solution to a technically challenging design. Unique design The stadium bowl façade is a uniquely designed system which embodies the visual simplicity and transparency of the iconic stadium structure, in accordance with the stadium architect’s conceptual desires. Peaking at 40 m high, 20 000 m2 of perforated powder-coated aluminium standing seam sheeting follow an extraordinary geometry defined by the external surface of the bowl structure. Each bay of steel box support beams presents a warped surface of variation as the wall of cladding rakes outwards from the vertical to an angle of 28° off vertical. A solid foundation The solidity of the primary reinforced concrete framework ends 17 m off the podium, and hangs on to pinned steelwork columns that support the curving compression ring. This implies that above 17 m, the structures are required to rack and sway in sympathy with the imposing service behaviour of the stadium arch and its suspended tensile fabric roof structure. Seamless integration The aluminium extruded façade fins make the upward transition from

With uniquely designed components, the completed system accommodates the magnitude of wind speeds associated with coastal position, varying warp geometry, and inservice racking and swaying. Thorough groundwork A pivotal feature of the system was the concept, design development, and testing of the unique grade 316 and 2101 duplex stainless steel ‘ball bracket’. In parallel to this was the concept development, prototyping and testing of the injection moulded nylon ball girt brackets, with stainless steel inserts and fixing bolts. From concept development to full non-linear analyses of the aluminium fin components carried out with Femap with NX Nastran finite element analysis software, the design team were constantly aware of the performance complexity demanded of the 14 000 m of extrusions. Success is in the detail Precise 3D geometry definition was required to develop and shop detail the fins, which weighed in at some 300 tons. Survey methodology was
implemented to enable bracket setting out, swivel, alignment and fixing in situ, at over 2 000 different positions. This façade took 12 months to develop, design, manufacture and erect, proving that South Africa is indeed a world-class destination for prestigious sporting events.

The winning projects
Seven Fountains Primary School 460 primary school children were evicted from their farm school in Shayamoya Township in January 2004. Temporary accommodation was found for the children and in 2005 East Coast Architects were approached to design the new school. With no recreational facilities, the brief was to design a new KwaZuluNatal Department of Education ‘standard’ primary school to accommodate 1000 learners. R12-million was allocated to each school and the basic facilities were specified. The architects were charged with providing a model for emulation while meeting the departmental standards of accommodation, budget and size. By engaging with the community throughout the decision-making process and challenging the standard plans and typologies, they came up with a well-resolved plan. The building skillfully mediates the natural fall of the site and the curvilinear and orthogonal layout of the township while interacting with playgrounds and sports fields that are accessible to the school and its community. A Kokstad-based main contractor was employed to ensure that as many local people as possible would be employed to work on the contract – many of these employees were parents of learners who would be attending the new school. Fifteen local women, all mothers of learners, were also employed to manufacture 16 000 sun-dried adobe bricks which were later used to build a classroom. Careful consideration was given to the positioning and size of windows and chalkboards to ensure that the use of artificial lighting is minimized. The harsh climate conditions of the area prompted the architects to use a passive solar design to level the thermal variation curve and create warm winter and cool summer teaching environments. Twenty percent of the site was allocated to the permaculture gardens which will contribute to the school’s feeding scheme. Rainwater harvesting and storage, as well as grey water recycling for the flush toilets, help the school to reduce its water usage. Timeball Square The brief for Timeball Square in Durban called for the design of a device which would give visual structure and orientation to the area being redeveloped. CNN Architects also had to incorporate an information kiosk and public ablutions in conjunction with the open-air theatre around the artificial canal. The harbour site historically contained a timeball, which prompted the architects to re-interpret this design in a contemporary fashion, with the needle taking its inspiration from traditional bangles on the base. It revalidates vestiges of the destroyed stone wall built by political prisoners of the Bambatha Rebellion and concealed ablution facilities, which are naturally ventilated, are concealed behind this wall. What was required for Timeball Square was a work of public architecture, one in which art and architecture blur. The structure, detailing and materials make strong references to both history and location.

Wall coatings
at the Moses Mabhida Stadium in Durban
Cemcrete’s high-quality cement-based wall coating, called CemCote, has been specified for certain wall areas at the prestigious Moses Mabhida Stadium. Cemcrete, the manufacturer of a wide range of cement products in South Africa, is proud to be involved with this 2010 FIFA Soccer World Cup stadium in Durban which is now nearing completion in time for the tournament. Joanne Bendall, Cemcrete’s director and brand manager, says that CemCote is increasingly specified for large-scale projects in South Africa. “We are delighted CemCote has been used in the Moses Mabhida Stadium. This has now added to our growing list of prestigious projects that Cemcrete has been involved with, which includes high-profile venues such as the Cradle of Humankind.” Cemcote is a finely ground mixture of white Portland cement, pigments and chemicals that is mixed on site to provide a colourful, textured and waterproof coating to the wall. This durable coating sets rock hard and one of the features that has made it popular is the fact that it is unaffected by rainwater and UV light. CemCote is recommended for use as a two-coat finish, suitable for both interior and exterior surfaces of houses, factories, outbuildings and boundary walls.
www.durban.gov.za
The main purpose of CemCote is to provide a tough, economical coating for direct application to off-shutter concrete, cement plaster, cement wash, fairface brickwork, and natural stone. When applied to off-shutter concrete, CemCote will improve the uniformity of colour. Pricing and coverage Regional pricing of this multipurpose wall coating differs due to delivery costs to the branches, but guideline prices are R195 excl VAT for 5 kg container; and R730 excl VAT for the 25 kg version (these prices are quoted ex-Johannesburg warehouse and do not include application). CemCote’s coverage depends on the suction of the surface it is applied to but it is approximately 25 m2 – 50 m2 per 25 kg bag per 2 coats. A new flooring product, called CreteCote, has also been launched (more information on this new product by CemCrete will be made available in a future issue of FLOORS in Africa).

Specifically designed awnings to accommodate the variants of dimensions at Bedford Square.
Creating space for the DIRCO The new Department of International Relations and Cooperation’s premises in Soutpansberg Road, Pretoria, selected Aluglass to provide a solution for the DIRCO’s need for multi-function conference and VIP rooms. Variflex was used to meet the DIRCO’s need to provide a single integrated partition solution that could allow the flexible subdivision of meeting rooms. With the Variflex system, rooms can be subdivided so that two meetings can be held adjacent to one another in complete privacy. Walls are sturdy once locked into place, and when the full-sized room is required, the elements are easily moved on an overhead track and positioned neatly to one side or into a cupboard or niche. For large conferences, the full use of the room is then available, requiring no unattractive, not to mention unsafe, floor track. Locally produced Although the entire Variflex system is produced locally by Aluglass, there is a licence agreement with Dorma Hüppe in Germany, one of the world’s leading acoustic partitioning contractors, where technical backup and international design standards are available. For functional styles that combine feature products and reliable service, Aluglass have solutions that will lend any space a luxury feel.
Bedford Square Aluglass has also recently created customised awnings for Bedford Square. This upmarket Mediterranean-themed complex provides prestigious residential, business, recreational and retail facilities in the east of Johannesburg and they needed a specific awning solution to accommodate the variants of the dimensions in which the buildings were built. This unique project led Aluglass to create a tensile fabric that was specifically designed to be able to fit over the existing gutter system. The awnings that Aluglass made for Bedford Square are rectangular canopies, in Ferrari Soltis Stretch fabric. There are 12 canopies in various sizes in the region of 4 m x 4 m by 1,5 m high. Aluglass tackles every project with a team of highly skilled workers that use their industry knowledge and product expertise to customise products to meet the goals of architects and builders. Other projects that Aluglass have been involved in include the SABC, Crystal Towers, International Convention Centre Durban, Sun City, Durban Exhibition Centre, Sandton Convention Centre, Gaborone Convention Centre and Cape Town International Convention Centre and many more.

Sun louvre solutions for the new International airport
An artist’s impression of the new King Shaka International Airport on KwaZulu-Natal.
The R7,0-billion King Shaka is South Africa’s latest airport which will be completed before the flood of soccer fans comes to South Africa in June 2010. According to MediaClubSouthAfrica.com, KwaZulu-Natal is the second fastest growing province in commercial and industrial terms, contributing approximately 17% to GDP, but it hasn’t been able to keep up with the commercial hub of Gauteng, partly due to its inferior airport facilities. Durban International is expected to reach capacity by 2015 and King Shaka has been designed to expand in stages, making it the large, international airport that KwaZulu-Natal needs to reach its full potential. Hunter Douglas SA, a specialist company fabricating aluminium cladding, sun louvres and ceilings for the architectural industry, provided a range of solutions for the construction of this project. “Hunter Douglas was in a unique position to provide a variety of products and specialist services
for the King Shaka airport,” says Luigi Zito, General Manager of Hunter Douglas SA at the head office in Randburg. “The project involved design and installation of various Hunter Douglas products for this public facility of international stature.” Hunter Douglas products used at King Shaka airport: • External Sun Louvres • 132S • 70S • Filigree • Aerofoil 300 AF • 300 Aerowing • Celoscreen
The sun louvres had to conform to stringent engineering specifications to meet the needs of the architects and engineers on the project.

Hunter Douglas had to conform to stringent engineering specifications due to the fact that they had to satisfy the needs of architects and engineers, both on the public side of the project as well as the air side. During the planning of the project, Hunter Douglas had to overcome hurdles and provide innovative solutions to meet the needs of those engineers and architects working on building this huge airport. “Working on such a large project means that everyone has different specifications that can’t easily be modified,” explains Zito. “The engineers of King Shaka needed the airofoils to withstand a high wind load. Hunter Douglas was able to adjust the fixings and spans of sun louvres, without changing the actual spec, so that the required outcome could be achieved.” Over 3 000 m2 of Hunter Douglas Sun Louvres were supplied and fitted, of which Aerofoils and the 110 HC were used extensively. The 110HC Sun Louvre system is made of extruded aluminium panels and the product has a robust and high-tech appearance which proved to be ideal for the King Shaka airport. The chief architect of the project, Fred Burkett from Osmond Lange Durban, says that the Hunter Douglas products were chosen for their aesthetic features as well as the low maintenance that the product requires. “We really liked the look of the product,” says Burkett. “Aluminium is also a maintenance-free product, which was ideal for the King Shaka airport.” The King Shaka airport is being built by a consortium of engineering firms, architects and contractors called the Illembe building joint venture. Keith Willoughby, the project director of Illembe, says that even though there are many different companies working together, the project is going as planned. “Overall, King Shaka is on target for completion as per the

Why choose
roller shutters for shop fronts?
Roller shutters can be used where other security barriers sometimes can’t due to either space or logistical constraints. They don’t require wall space as they roll up in their own frame into an overhead bulkhead, affording interior designers and shop owners more floor area to use for merchandising, decorating or the flow of traffic. What’s more, they can serve as both a front door / back door and a security barrier. This two-in-one package makes considerable cost savings possible. All-important style and function “In terms of aesthetic design, roller shutters have come a long way, but their basic purpose is still to keep criminals out,” explains Kevin Bonner, Roll-Up Serranda’s marketing and sales executive. He adds that goodquality shutters combine style and function very well. From solid steel panels to perforated patterns in both steel and aluminium, there is a wide choice of designs available, and the shutters can be powder-coated to suit the building’s finishes or left as plain galvanized steel. Specific requirements such as air circulation, high visibility or no visibility at all, protection against extreme conditions such as fire, excessive winds or crowds of people can also be accommodated in the roller shutter design. Enhanced security When opened and rolled up into the bulkhead or ceiling, roller shutters are invisible, meaning customers and employees don’t feel locked in or claustrophobic. The doors are effortless to operate, especially when automated, and can be quickly closed in dangerous situations such as shopping mall invasions by armed robbers. Both steel and aluminium roller shutters display considerable strength and are robust enough for frequent-use duty cycles. Built-in safety features make the doors virtually impossible to prise open once locked into place.

Number 1, 2010
More than 4 000 m² of walling with 6m spans between columns and heights of up to 10 m were designed and manufactured in Vela’s factory in Isando and installed by Browndeck, who are specialist lightweight contractors. “We believe that these dimensions make these walls among the largest ever constructed in lightweight steel in this country,” says Brent Harris, Managing Director of Vela. Cost effective and efficient According to Grinaker-LTA contracts director John McLaughlin, weight was a critical consideration for this project due to the fact that they needed to build on top of a parking area, and Vela’s solution was an ideal match for the needs of the project. “We considered alternate solutions and Vela’s was the most cost-effective given the special requirements and the fast-track nature of the contract. We are satisfied with the results,” says McLaughlin. Four types of structural walls were erected on the Eastgate project: Acoustic Walls; Screen Walls; Feature Cavity Walls and Standard Walls.

More commercial projects in the near future The new food-court and restaurant area at the Eastgate shopping centre was the company’s first commercial project for Grinaker-LTA and its success has led to a second project - supplying Grinaker-LTA with 560 m² of lightweight walling for the new Heineken Brewery in Kliprivier. Vela has developed a notable reputation for its innovation in lightweight steel manufacture. Vela’s wall panels are used in the full gamut of housing from low-cost to upmarket and in commercial situations like Eastgate. The company’s lightweight ‘U’-Truss roof trusses have also become increasingly popular within the building industry. “Not only are our trusses lighter and thus proportionally less expensive, but they can also be flat-packed and delivered to the site, saving significantly on transport costs. Importantly, the ease of assembly and erection has made them the preferred truss system for erectors,” concludes Harris.
Primary steel frame being erected prior to fixing of lightweight steel.
All of the wall types included structural lightweight steel frames, various types of board cladding, skim plaster and internal insulation giving them their required characteristics. Vela contract manager Wayne Cumming says Vela’s design and manufacturing process followed a fixed procedure. “All our designs were signed off by an external engineer and our subsequent working drawings then approved by Grinaker’s engineers before production at our factory commenced,” says Cumming. “Once the primary structural steel frame was erected by other contractors, its dimensions were accurately measured to ensure the perfect fit for the Vela panels, which were rolled and pre-assembled in the factory and delivered to site on a just-in-time basis.” Advantages of the lightweight steel walling system: Speed of erection: Vela’s lightweight steel structures are erected in a short time-frame, which translates into significant cost savings due to a shorter programme and lower P&Gs. Weight reduction: The lightweight Vela system ensures significant cost savings in foundation design. More usable interior space: Due to the thinner wall profile, the usable interior space, with the same stand coverage, is larger than if conventional materials were used. Energy saving: Light steel frame walls provide excellent insulating properties leading to savings in energy. Also, adding to the environmental and sustainable benefit is the fact that the steel is recyclable and there is minimal waste removed from site. Easier installation of services: Service holes are pre-punched in Vela’s wall panels for services to run horizontally or vertically without the need for “chasing” walls.

The tile is fixed in the conventional manner to the timber structure, primarily for new roof application. It is also used for re-roofing over existing sheet metal roofs by first fixing timber purlins to the existing roof in preparation to accommodate the sheet. As with all the roof sheets, start laying from the prevailing weather side, using the male rib first.
The roofing profile is available in a variety of thickness and in various colour.
Before starting work ensure that: • The purlins for your cladding are true ie. in the same plane (level and flat) • The minimum roof slope is not less than 7,5˚; and • The overhangs of sheets from the top and bottom purlins don’t exceed 150 mm, whilst also overhanging at least 50 mm into gutters. Make any necessary adjustments before you start laying sheets because they will be difficult or impossible to rectify later. • Make sure you start with the male rib facing towards the direction you want After fixing the first sheet in position, align the following sheets using: • The long edge of the previous sheet; • A measurement from the end of the sheet to the fascia or purlin at the gutter. It is important that you keep the gutter-end of all sheets in a straight line. Fix the sheet by either: a) fixing each sheet completely before proceeding to lay the next; or b) fixing the sheet sufficiently to ensure it can’t move, complete laying all sheets, then return to place all the intermediate fasteners later. Check alignment occasionally. Storage and handling Ensure that the product remains dry and clear of the ground. If the product is stacked or bundled and it becomes wet, separate the sheets, wipe them with a clean cloth and dry thoroughly. Avoid damage to the material by handling it carefully – don’t drag materials over rough surfaces or each other and protect it from swarf. Optimum product life of Versatile will be achieved if all external walls are washed regularly. Areas not cleaned by natural rainfall should be washed every six months.

New writing walls
launched in the South African market
Vitrex has developed a new product, vitreous enamelled steel Writing Walls, by using the company’s architectural cladding panels to create large writing surfaces. Writing Walls are a first for South Africa and the product can be custom-made by Vitrex at its Jet Park factory to suit specific room layouts and wall sizes. Besides the fact that these walls can be customised to suit your space, they also offer the advantage of greatly increased writing surfaces compared to traditional writing boards. “The writing walls can be supplied with graphics and screening options and they are ideal for meeting rooms, boardrooms, computer rooms, laboratories and ‘think tanks’,” says Cristian Cottino, Sales and Marketing Director of Vitrex. Ideal solution for advertising agencies and meeting rooms The first installation of a Vitrex writing wall was recently completed by the company at the Sandton premises of a leading advertising agency. Designed by Design Inline, five white Vitraclad Heavy Gauge panels make up the 5m long writing wall which is 2m high. Vitrex subsequently also secured a contract for a 5,6m long and 2,4m high writing wall for the Venue Operations Centre meeting room at the 2010 Soccer World Cup Moses Mabhida Stadium in Durban. Five Vitraclad panels in a Light Gauge construction, fitted to bespoke support elements, will make up the writing wall specified by the Architects, Ibhola Lethu Consortium. In both instances, the colour of the enamel surface of the panels was a standard White. The new Vitrex Writing Wall in Sandton, Johannesburg.
Why Vitreous Enamel is the better choice According to Cottino, the alternative painted steel surfaces, often categorized alongside vitreous enamel (VE) steel by a number of other manufacturers under the generic banner of “magnetic surfaces”, and the high pressure density laminate writing surfaces, also referred to as a “nonmagnetic” - although cheaper in the short term – cannot match VE steel, in terms of material construction, properties and ultimate performance. A VE steel writing surface is created when an inorganic coating of glass, oxides and minerals is fused to an enamelling quality steel base at temperatures of around 820OC. Cottino says a VE surface is the ideal writing surface, particularly in high-use applications, because of the following advantages: • Ease of cleaning: VE surfaces can be cleaned very easily with a damp cloth and mild alkaline soap. • Ghosting: Over time, VE white board surfaces do not exhibit what is known as “ghosting”. Ghosting occurs when pen marks cannot be com- pletely removed, even with the use of chemicals and vigorous cleaning, as the ink itself has been partially absorbed into the surface, due to the porous nature of the alternative writing surfaces. • Extreme surface hardness: VE surface hardness is similar to glass. On the MOH scale, VE has a rating of approximately 6,9 which allows the surface to resist mechanical abrasion and prevent scratching. • Resistance to chemicals: Solvents, acids and alkalis do not affect the enamel surface. When a permanent marker has been used in error this can simply be cleaned with commercially available White Board cleaner. In instances where graffiti has been applied or paint may have fallen on the board, these marks can easily be cleaned off with thinners and then washed using a detergent and water; enamel uniquely can be cleaned with thinners without any damage to the surface or finish. • Colour fastness: Enamel colours are unique in appearance, fade- proof and resistant to ultra-violet light. Lines, designs and logos can be incorporated permanently into the surface. • Hygienic: Due to the absence of pores, the smooth, hard enamel surface eliminates the absorption of dirt and grease, reduces the presence and growth of bacteria and mould, and creates a more hygienic and healthy environment. VE writing surfaces are ideal for application in hospitals, clinics and laboratories. “Vitrex has been manufacturing writing surfaces for over 50 years and we guarantee our VE writing surfaces in respect of normal usage, against fading, deterioration or failure of component vitreous enamelled parts for 20 years,” Cottino concluded.

South African architect wins World Building of the Year Award
Peter Rich, an architect from Johannesburg, Gauteng, won the World Building of the Year Award at the 2009 World Architecture Festival. This festival took place on 4-6 November in Barcelona and Rich won the award for the Mapungubwe Interpretation Centre in South Africa, a building on the site of an ancient civilization. The jury of the competition, chaired by Rafael Viñoly, also included Kengo Kuma, Farshid Moussavi, Suha Ozkan and structural engineer Tim Macfarlane. The panel had a tough task in deciding on an overall winner this year due to the different types of projects that were submitted. Besides Rich’s winning Mapungubwe Interpretation Centre, jurors were also impressed with a number of schemes – such as the redevelopment of Father Duffy Square in New York by Choi Ropiha, Perkins Eastman, PSKB Architects and WOHA´s Bras Basah Mass Rapid Transit Station in Singapore. It was only after a lively debate in the final analysis of the competition that the jury agreed on Rich’s project to be the most architecturally and aesthetically powerful project. “It carries both weight and a message of complexity to the outside world,” commented one of the judges, Suha Ozkan. The jury concluded that the way in which the Mapungubwe Interpretation Centre related to the land and made graceful virtues of the challenging issues of sustainability, politics and social improvement made it a highly deserving winner. New, refreshing and environmentally aware Peter Rich believes the jury found that there was depth in all the issues which brought the Interpretation Centre about. “The building was something that was rough and hand-crafted, it was made to convey meaning. In today’s architecture, there is so much slickness and style – the jury of the World Architecture Awards found it refreshing to find something authentic that grew out of a context. The building is new, fresh and devoid of fashion or style,” says Rich.

Rich also believes that the jury had a difficult task in deciding an ultimate winner because one couldn’t simply decide between the competing projects. “It was pretty humbling to win the award because many of the projects were so competent in their situation,” says Rich before adding that the environmental aspects of the building were definitely one of the factors that set the Interpretation Centre apart from other projects. “The building process had an 80% less carbon footprint than conventional buildings. Virtually no cement or steel was used, it didn’t involve transport, no carbon emissions, etc. The Interpretation Centre is rooted in earthiness and the green aspects were genuinely embedded in the project – it wasn’t just a piece of fancy footwork to give the building a green label,” says Rich. Rich believes that winning the World Architecture Award will help create more interest in the South African architecture industry. “There’s suddenly a lot of curiosity and interest in Africa and South Africa and this award just affirms that interest. Hopefully, it will also raise the bar and bring more work to architects in South Africa.” Mapungubwe Interpretation Centre The Mapungubwe National Park celebrates the site of an ancient civilisation within the context of a natural setting. The source of materials and design for the Interpretation Centre was inspired by the complex landscape and indigenous fauna and flora of this region. Dramatic geological events that resulted in the Limpopo River changing its course from flowing into the Atlantic Ocean to discharging in the Indian Ocean formed a mesa. The Interpretation Centre is set on the side of this mesa and the building is visually contained by two hollow cairns. Timbrel vaulting was used to construct enlarged wave forms that expose the arched edges of their thin shells, creating an analogy of the archaeological revelation of past cultures. The building evokes an abundance of experiences, highlighting the complex social interactions of the various cultures that have walked the site. Steel screens that echo the network of branches of indigenous trees help to temper the sharp southern light. The inside space of the building is spacious and cavernous, articulated by the exposed tiles that were made by locals of the area. The building is naturally ventilated and cooled by mass and evaporative cooling. Light that reflects from the outside ponds gets filtered through fused coloured glass and reflected on the inside forms of the vaults. The agenda of the Interpretation Centre is to evoke an understanding of the area’s history as well as the fragility of the local ecology and these goals are manifested in the construction process. Unemployed people from the area were trained to manufacture stabilised earth tiles and they were also involved in building the vaulting of the building. Besides the World Architecture Award, Mapungubwe Interpretation Centre also won the Holcim Award for Sustainable Construction (Acknowledgement Prize, 2008) and it was short-listed for the David Alsop Sustainability Award (Institute of Structural Engineers – Structural Awards, 2009).

Ceiling solutions for King Shaka International Airport South African specialists in ceiling and partition systems, Capco, supplied the new King Shaka International Airport in Durban with over 25 000 m2 of their products. Barry Gould, Managing Director of Capco, says that the products were specified due to their ease of use and high quality. “When taking on such a large project, it’s important for customers to know that the products they are buying are going to last and that they will be relatively easy to install,” says Gould. “The result is a highly functional, aesthetically appealing system for the new King Shaka International Airport.” Another feature that also drew the Airports Company of South Africa (ACSA) and Bambanani Joint Venture to Capco’s products is the special curved design capability of the ceiling systems. Although the ceiling systems are developed to satisfy the requirements of the designer, the systems also cater to the practical onsite problems faced by the installer. “The ceiling contractor’s expertise and the nature of the product allowed them to install the durable systems with ease,” says Gould. The specific products that were used include CKM’s metal tray ceiling tiles and suspended ceiling grid, as well as Daiken’s mineral fibre acoustic ceiling tiles. A notable feature of the metal tray ceilings that were used was the “island” design where independent islands appear to float. A special ceiling tee closer was designed by Gould to finish off the surrounding edges. CKM’s leading international ceiling systems include: • Exposed Tee Grid Systems – Made from galvanized mild steel and finished with special pre-painted steel capping. Production lines are fully automated and computerised to produce superb quality and precision. • Metal Tray Ceilings – Available in galvanized steel or aluminium epoxy-coated metal trays using either an exposed tee grid or con cealed clip-in framework.
Ceiling systems that cater to the practical on-site problems faced by the installer.
Unique features of Daiken mineral fibre acoustic ceiling tiles: • Outstanding fire resistance. Not only are these tiles non-combustible, but they are also less likely to emit toxic gas and smoke, or to melt, break or become deformed under normal fire conditions. • Effective thermal insulation. Daiken mineral fibre acoustic ceiling tiles offer thermal insulation more than six times that of gypsum board. This superior thermal insulation characteristic ensures that room comfort is maintained at all times, greatly saving cooling and heating expenses. • Superior sound absorption. Create a comfortable and quiet environ- ment with ceiling tiles that can absorb sound. • Relative humidity resistance. Daiken mineral fibre acoustic ceiling tiles are guaranteed to resist visible sagging of up to 50ºC and 99% relative humidity (guaranteed by Capco for 10 years). • Easy installation and maintenance. These tiles can be installed using standard exposed tee Suspension Systems and they can be easily removed for maintenance. • Asbestos-free. Daiken mineral fibre acoustic tiles are asbestos-free. Use of asbestos, which can have adverse effects on the human body and the environment, is eliminated. Daiken’s commitment to the environment In 1952, Daiken began working on the development of the “Daiken Board” wood fibre board that effectively utilizes wood waste. Since that time, Daiken has been able to introduce various products and systems that are friendly to our planet, such as the mineral fibre board called Excel-Tone MR ceiling tiles with excellent thermal insulation properties for energysaving construction methods, which is made from mineral fiber and volcanic silicate, previously untapped sources of raw material. Daiken products are focused on developing products and systems from an environmental standpoint, fully minimizing waste generation in manufacturing processes and waste output. As a result of this, the Daiken Okayama plant and other primary production plants have earned ISO 14001 certification. Why choose Capco for your projects? Management at Capco have over 35 years of experience and their expertise has given Capco the ability to translate special design specifications of architects, designers and customers into functional products that meet strict design criteria. Capco offers systems that provide unique aesthetic and design options. The ceiling and partition systems are considered to be top-quality products and Capco develops long-term relationships with its customers.
The tiles are non-combustable and they are able to provide effective thermal insulation.

A short portrait of the Libeskind
Villa
The aspect of the Libeskind Villa is reminiscent of a crystal growing out of the ground. Dynamic lines reinforce its powerful charisma, while the interplay of sunlight and clouds lend its outer surfaces a fascinating vitality. The interior of the building is impressively characterised by openness and transparency, and offers extraordinary spatial experiences. However, the component elements of its environmentally friendly building services engineering remain hidden to observers. The RHEINZINK reception building, designed by Daniel Libeskind, is a clear expression of design and sustainability. The villa stands for aesthetics, exclusivity, first-class materials, innovative energy management and sustainable construction. And, as a part of the ‘Signature Series’, the designer-living concept by Berlin-based proportion GmbH, it is also representative of a new type of residential architecture. In collaboration with prominent international architects, this enterprise plans residential sculptures that are characterised by unusual contemporary architecture and that are built in a strictly limited series around the globe. The first construction of this new architectural concept was designed by Daniel Libeskind. Together, acute and obtuse angles, canted and vertical walls, interlaced construction elements, flowing transitions of inner space and a balcony with elaborate visual and sun protection create a unique ambience embedded in unmistakeable architecture. Metal roofing and facade panels enwrap the structure to create an impressive, integrated work of art.

As the prototype of the Libeskind Villa was realised as a reception building rather than a residential property, RHEINZINK GmbH & Co. KG has made use-specific adaptations to certain parts. The imposing entrance hall serves as a reception area and foyer. From here, an open stairway in folded-plate construction leads to the upper floor and its numerous conference rooms. The ground floor also houses a further conference room, in addition to utility and services rooms and – oriented towards the entrance – a room for plant security. The architectural highlight of the Libeskind Villa is the Grand Room; a room with heights of up to seven metres that, thanks to its generously dimensioned window areas and dramatically exaggerated ceiling construction, radiates an imposing dynamism. The Grand Room is accessible from the foyer and offers a spacious venue for events and exhibitions. RHEINZINK informs visitors about the company and its history and presents its products and technologies in the impressive ambience of this room. Materials and technologies The Libeskind Villa was built as a timber-frame construction employing sustainable building methods. In addition to the use of wood, as a renewable raw material, all parts of the building employ materials which, like RHEINZINK, possess an ECO product declaration from the Bauen und Wohnen e.V. institute in accordance with ISO 14025, Type 3, or which have been awarded certificates as environmental innovations. The roof and facade panels from RHEINZINK are part the innovative energy concept and contain a solar heating system that remains completely invisible from outside the building. In combination with a geothermal energy absorber and heat pump technology, this system provides an
impressively creative and simultaneously sustainable heating system. A new form of mineral wool with extremely low thermal conductivity of 0,32 W/m²/Kwas employed for insulation purposes. An intelligent climatic floor construction provides the basis for heating, cooling and waste heat recovery. Rainwater from the RHEINZINK roofing elements are collected in a tank and used for flushing the toilets. Fittings such as windows, doors, washbasins, taps and sanitary installations are manufactured from highest-quality materials, while state-of-the-art electrical and lighting systems combine intelligent building services engineering with comfort, safety and aesthetics. The performance of the various hidden heating, cooling and ventilation systems of the building can be monitored on an interactive display screen installed in the Grand Room at any time. The data is recorded over a period of three years and provides detailed information on the efficiency of these systems. The Libeskind Villa has a floor space of around 200 m² (ground floor: approx. 200 m², upper floor: approx. 115 m²) and its construction was completed in a period of only six months. The extraordinary architecture, the craftsmanship in its construction, the use of highest-quality materials and the environmentally aware energy concept set totally new standards with regard to design, craftsmanship and sustainability.

Payback to costing –
what do your improvements cost? Climate change, electricity cuts and energy problems are forcing South Africans to innovate and take on more initial investments in their projects to reap the benefits later on. When deciding to make changes to a building for the sake of energy-saving improvements, you want to be able to justify the costs. More often than not, a green venture will require more initial capital investments. Walls & Roofs investigates the payback period to costing and how you can determine what your investments will be saving you in the long run. The payback period The payback period focuses on recovering the costs of your investment, projects or ideas and according to Valuebasedmanagement.net, a payback period can be calculated as follows: PP = (The costs of project/investment) / Annual cash inflows This concept holds that if all other things are constant, the better investment is the one with a shorter payback.

period calculation: A project costs R400 000, the expected returns of the project is R80 000 every year. The payback period would be R400 000 / R80 000 = 5 years. According to WBDG.org, Life-cycle cost analysis (LCCA) takes all costs of acquiring, owning and disposing of a building or building system into account and it is especially useful to compare product alternatives that fulfil the same performance requirements, but differ with respect to initial costs and operating costs. The purpose of an LCCA is to select designs that will provide the lowest cost of ownership. These calculations help with selecting the option that maximises net savings but LCCA shouldn’t be taken into account with budget allocation considerations. A life-cycle cost analysis should be done at the beginning of the design phase of buildings so that the effects can be quantified and expressed in monetary amounts.
Some of the features of the Strey residence that required initial, large capital investments include solar underfloor heating, grey water recycling with an on-site filter and more (an in-depth look at the house is on p.12-13 of the July/August 2009 edition of Walls & Roofs). Although the Strey pair didn’t have exact payback period calculations, they estimate that all the modifications made to the house to optimise heating, cooling, energy efficiency and water usage costs around 10% 15% of the price of the house and it will have paid for itself within five to eight years, but with the new electricity price increases the payback period will come down to two or three years. There will be six hot water cylinders that are heated by the sun, a 20 000 litre rain water harvesting tank for interior use, 1 000 litre grey water tank with fat trap filters for irrigation purposes and day/night motion sensors to switch lights off automatically when nobody is using the area, in order to save electricity. At the moment, water is still cheap for South Africans – we turn open a tap and water comes out, we don’t think about where the water is coming from, but water isn’t going to be available or cheap forever. Many communities already have run out of water. Sedgeway’s water supply, for example, is at a critical level and they will need to receive water from George. The sooner you make these types of changes to your home, the less hard you will get hit by energy hikes and water restrictions,” says Strey. Friedrich Strey, owner of Strey Architects, advises people to look into building a house that is 10% smaller than what you initially intended. The money from the 10% cut back can be used to put proper insulation in your
Green feature paybacks Jóhann Strey and Friedrich Strey, from Pretoria-based Strey Architects, are busy building their new work space and Friedrich’s family home in Southdowns residential estate in Irene. These architects have focused on green minded designs for the Strey residence since the beginning of this project. “Building your home to save energy is initially expensive and the problem is that South Africans want the biggest homes for the least amount of money,” says Jóhann Strey. “As architects, we believe that we have to set an example and show people that putting money into your home to reduce energy costs in the long run and increase future savings, is possible – it can and should be done.” Although the initial investments are more, running and operating costs will be much cheaper in the long run.

home’s floors, walls and roofs. One can also use double glazed windows and solar heating, which will save approximately 50% on electricity costs. (For more information on how to save electricity in your house, visit www.streyarchitects.co.za) On the WBDG.org website, the WBDG Cost-Effective Committee writes that it is impossible to summarise cost-effectiveness by a single parameter. Every owner wants a cost-effective building, but this interpretation is influenced by an individual’s interest and objectives. • Is it the lowest first-cost structure that meets the program? • Is it the design with the lowest operating and maintenance costs? • Is it the building with the longest life span? • Is it the facility in which users are most productive? • Is it the building that offers the greatest return on investment?
Using figures and numbers instead of guessing The main advantage of doing a life-cycle cost analysis is that it lets you make an informed, logical choice that is based on facts and figures (as opposed to assumptions). Although carrying out a life-cycle cost analysis might be time-consuming, it is worth the effort when you are able to see what your initial investments and wise building decisions will be costing you in the long run.

Concrete’s role in the
durability of buildings As global concern about environmental preservation continues, appreciating concrete as a building material is proving to be increasingly important. Although concrete is the most commonly used building material in the world, much of what it can offer as a sustainable material is overlooked, according to Daniel van der Merwe, architect at the Cement & Concrete Institute (C&CI). “Materials specification must play a critical role to reduce the embodied energy in a building. Materials manufacture also needs to be factored in terms of measurable emissions, energy and finite material consumption. Buildings must now be constructed with a longer lifespan in mind, with the emphasis on durability and retrofitting rather than demolition,” says Van der Merwe. The cement and concrete industry is proving their commitment to responsible manufacturing by managing to boost their production while decreasing the use of raw finite materials. “Cement producers have already reached 50% of the set target of the Department of Minerals and Energy which calls for a 15% reduction of energy consumption by 2015. Through the use of alternative fuels and resources, including hazardous waste and scrapped tyres as a fuel source, further reductions are possible.” The fitting of bag house filters, or electrostatic precipitators, is further reducing particulate emissions. Chemical admixtures are also helping to reduce the cement and water content in concrete mixes. “New permeable concrete pavers, soil erosion blocks and embankmentstabilising blocks save water and prevent stormwater run-offs and flooding; and self-compacting concrete in sustainable developments allows for architectural achievements previously regarded as impossible,”

Concrete buildings offer unparalleled durability
says Van der Merwe before explaining how new research is producing exciting data on the re-absorption of carbon dioxide by hardened concrete. “A Danish study has found that 50% of the volume of concrete will be ‘carbonated’ over 70 years of any building’s service life. This sponge effect makes concrete a greener choice than previously thought. And it emphasises how global sustainability can be achieved with concrete,” says Van der Merwe.

Why we are paying more attention to
operating and maintenance costs Cristian Cottino, Sales and Marketing Director at Vitrex, believes there is a growing appreciation of the necessity to correctly account for operating and maintenance costs in payback period calculations amongst individuals and industry practitioners. Whether this is being done purely for financial reasons or to secure large projects is not important, as this paradigm shift is needed to ensure less waste and more efficient building. “We have seen an increasing awareness and interest on the part of owners, designers and end-users in assessing the impact of operating and maintenance costs on the payback period of a project, as essentially this determines the point at which returns can be expected on what could be a substantial investment,” says Cottino. The trend has not only been noted globally, but is also becoming increasingly evident on various construction projects in Southern Africa. Cottino believes that the reasons for this include: Responsibility for operating and maintenance costs continues after construction: The number of projects, particularly large-scale projects, where the contract is awarded on a ‘design, build and operate’ basis is growing. Examples of such projects would be the Gautrain Rapid Rail System (15-year maintenance period), the Singapore Sports Hub in Singapore, a new sports venue incorporating a major stadium and ancillary sport facilities within a retail and office environment (25-year maintenance period) and the Northbridge Vehicular Tunnel in Perth Australia (25-year maintenance period). Responsibility for operating and maintenance costs is shared The increasing number of Public Private Partnerships (PPPs) which see Government or large corporations forming a partnership with a professional team of architects, project managers, quantity surveyors and a main contractor to share not only the initial costs and risks amongst partners but also to shoulder the future costs of operating and maintaining the facilities. The attraction of such a venture rests in the fact that the partners will obviously be able to share in the expected profits generated by their investment, after the payback period. A recent example of this type of contract is the complex built in Gaborone (Botswana) for the Botswana Diamond Valuing Company (BDVC), where Debswana's entire production of diamonds from the Jwaneng, Orapa, Letlhakane and Damtshaa mines is sorted and valued.

Number 1, 2010
Increased awareness of clients: Clients are more aware and more knowledgeable about assessing the viability of a project from an investment perspective. They understand that there is a need to accurately account for the real impact of operating and maintenance costs on their bottom line. Rising costs: Increasing costs of maintaining and refurbishing existing facilities, not only in terms of labour, equipment and materials, but also in terms of lost productivity and optimum utilisation of the facilities have lead people to be more concerned with the payback period and operating and maintenance costs. Increased accountability of designers: Designers increasingly need to account for the sustainability aspects and requirements of a project. Designers are not only tasked with accounting for the energy input at the design and building stages of a project in terms of the work to be carried out as well as materials used in the process, but also in terms of the future energy “footprint” of the building or facilities. Questions are asked regarding the life span of a product, how long before certain elements and finishes need to be refurbished or replaced, what type of chemicals are required to clean a specific surface and how harmful or toxic to the environment these chemicals are, how frequently we will need to clean and what are the corresponding labour and material costs are, and these types of aspects need to be taken into consideration by the designers. “Irrespective of the reasons for the trend, the fact that there is an increasing drive to account for operating and maintenance costs and a necessity to assess their potential impact on the payback period, in other words on the financial viability of a project, at an early design stage, is something that should be welcomed as we strive not only to maximise the returns for the investors, but at the same time we look at minimising waste and ensuring a more efficient use of our ever-reducing resources,” says Cottino.

technology for CSIR develops quick builds of
improved quality low-income housing
Even though South Africa is making huge progress to provide subsidised, low-income houses, a backlog of some 2,1-million homes is still a reality in our country. The Council for Scientific and Industrial Research (CSIR) has been collaborating to develop a technology that could be a solution for the low-income housing sector. According to Dr Sibusiso Sibisi, CSIR President and CEO, the technology being developed will allow houses to be built much faster, without increasing the costs of these homes. “Using innovative design and construction technology, CSIR researchers have developed a demonstration house with significantly improved performance and sustainability. If built according to CSIR specifications, and on large scale, such houses will be constructed much faster and at similar costs than when using conventional methods,” says Sibisi. This CSIR research project is supported by the Department of Science and Technology and a demonstration house was built according to the regulations of the National Home Builders Registration Council. The completed house has also been accredited by the internationally acknowledged body that provides assurance through technical approvals of non-standardised or unconventional products - Agrément South Africa. Changing the styles and adding flexibility Two other houses, which are both the standard 40 m2 size and design of subsidised low-income houses, have also been built on the CSIR campus in Pretoria. The one house is a replica of a properly built subsidised lowincome house and the other’s interior and exterior finishing is according to suburban style, illustrating the difference in appearance and experience when inside the house. The CSIR’s experimental house is the same size as the other two houses, but it has an optimised design with the added advantage that it can be extended easily by homeowners. “The house was constructed combining technologies and materials in an innovative way to improve living conditions and the durability of the home,” says Hans Ittmann, Executive Director of CSIR Built Environment. The CSIR also adapted a technology that it developed for roads to form the foundation slab of the house. Some contractors in the low-income market do not lay foundations to standard and this technology will eliminate
Using innovative design and construction technology, CSIR researchers have developed a low-income demonstration house. While being the same size as a government-subsidised unit (40 m2), it has significantly improved performance and sustainability.

cracked walls resulting from sub-standard foundations. "Local labour can be used to construct such foundations, which is based on ultra-thin, continuously-reinforced concrete technology," explains Ittmann. Building houses piece by piece “We used a modular, design-to-fit approach similar to a Lego set where pieces have to fit together correctly to form the bigger unit," says Llewellyn van Wyk, senior researcher at the CSIR. One of the major differences of the CSIR houses compared to current low-income houses is the design of the bathroom and kitchen area, and the use of a waste outlet manifold that is pre-manufactured, quality-tested and installed on site. The houses built according to the CSIR specifications and technology reduce the extent of the plumbing installation substantially while ensuring that the installation is done to the required standard. “Standard low-income houses have no ceilings and thus no insulation, which results in incredible variations in temperatures," explains Van Wyk. By adding an insulation material that doubles up as a ceiling, the CSIR was able to dramatically improve the thermal performance of the houses. The CSIR low-income housing initiative is a research project-in-progress. Recent additions to this project include a solar-powered geyser on top of the roof and a photo-voltaic panel above the front door for powering lights inside the house. Local authorities will have demonstration units constructed in the Buffalo City Municipality in the Eastern Cape and at Kleinmond in the Western Cape.

From cement to soapmaking PPC has invested R200 000 in the Calabash Trust, a non-profit organisation in Port Elizabeth that started a soapmaking project a year ago. Using a hands-on approach, the soapmaking team has been trained to produce high-quality glycerine soap and the Trust has since become a lifeline for 16 families living in Kwadesi and Joe Slovo townships. A local hotel in Port Elizabeth, the Summerstrand Hotel, is the Trust’s first client and they came on board after helping the Trust with their marketing, sales and product development. “After identifying a niche for high-end soap in the hospitality market, PPC made our dream a reality, helping us deal with the 70% poverty rate that Port Elizabeth’s township areas face,” explains Marion Gate, the Director and Co-founder of Calabash Trust. According to Francie Shonhiwa, the Corporate Social Investment manager at PPC, PPC looks for skills development initiatives when it aligns itself with projects such as the Calabash Trust because skills development is a key ingredient in helping communities in South Africa. “PPC will continue to fund the Calabash Trust and provide the support required to ensure that the initiative flourishes,” says Shonhiwa.

Timber Frame Builders Association
launches first training facility
The Timber Frame Builders Association’s (TFBA) first training facility was launched on 7 October 2009. The TFBA aims to build a national pool of qualified timber frame contractors by promoting a uniform level of timber construction knowledge throughout the country. Training programmes offered are approved by the South African Qualifications Authority (SAQA) and the goal is to ensure that the quality of workmanship by contractors will conform to the standards required by the Code of Practice for Timber Buildings in the National Buildings Regulations. "The timber frame construction system, which is rapidly gaining ground in South Africa, is vastly different from the traditional brick-and-mortar method, hence the need for proper training in this specialist field," explains Leon Bekker, national president of the TFBA. "The hands-on training to be provided will enable timber frame builders and the industry workforce to construct structurally sound, comfortable and safe structures, carrying forward the TFBA’s unblemished construction track record of nearly three decades." The curriculum includes both practical and theoretical components. It currently consists of seven modules covering all aspects of timber frame construction. The training courses, which are aimed both at those wanting to enter the field of timber frame construction as well as apprentices already employed in the industry, vary in length from five to thirty days. Trainees who successfully complete a course will receive an industry-recognised, SAQA-accredited certificate. The TFBA hopes also to introduce a learnership programme once the initial courses are underway. For more information, contact the TFBA, to which full acknowledgement and thanks are given.

Design an “icon
to earth’s wellbeing” competition
The human race is placing a huge strain on our planet and people from across the globe are trying to make a difference by changing the way we go about our daily lives. Designers influence, entice and determine the direction of a concept before it is brought to life and CaesarStone is calling on young designers to create an icon that addresses the earth’s sustainability and life in all its diversity. The winning student and his or her lecturer will be walking away with a trip to Israel worth R50 000. The task at hand is to design an “icon to earth’s wellbeing” on the most appropriate site in your home city. The icon can be anything – a building, artwork, statue or space and the site should preferably be in a place where it will have maximum interaction with people. Contestants must also motivate how this icon can be duplicated and placed in cities around the world, without losing its context and meaning. Earth is the contestant’s client and a fictional organisation called Sustainable Earth Alliance (SEA) is the facilitator. SEA, which is based on the Earth Council Alliance (ECA), is facilitating the earth’s needs and SEA is going to be looking for an architect or interior designer that can capture Earth’s message and entice a predestined reaction to it. The icon’s goal is to draw awareness to the Earth’s mortality. Submission formats for students and closing dates Students are required to submit 3 x A2 matt laminated drawings with accompanying disc in both high res and low res, in either jpeg or pdf format. 1 of the 3 matt laminated drawings must include a detailed drawing of how CaesarStone can be used in the design.

Thermal insulation standard SANS 1281-4 amended An important new edition of SANS 1381-4 has recently been published and it is believed this amendment, Materials for thermal insulation of buildings Part 4: Reflective foil laminates (rolls, sheets and sections), play an important role in how buildings are designed. Des Schnetler from SABS TC 1021, expanded (cellular) plastics and thermal insulation, believes that this edition of the reflective foil standard is long overdue. “The much needed and very overdue amendment of the reflective foil standard SANS 1381, Part 4: Reflective foil laminates (Rolls, sheets and sections) has been published by the SABS. Major changes from the previous publication in 1985 are the fire performance and resistance to accelerated aging of reflective foil laminates,” says Schnetler. “With the introduction of energy efficiency standards imminent by legislation to intervene and reduce peak electricity demand usage, thermal insulation and standards for thermal insulation, like this one, will play an integral part in the future design of a building.” According to Schnetler, the previous standard prescribed the surface fire index classification of thermal insulation materials to be determined

in accordance with SANS 10177, Part 3 Surface fire index of finishing materials. All reflective foil laminates will now have to be re-tested so as to comply with the requirements of SANS 428: Fire performance classification of thermal insulated building envelope systems. “Fire performance requirements for thermal insulation products can only be based on a fire test of the complete system for the respective use and application. In addition, the accelerated aging test will ensure products will last for 15 years as required by SANS 10400 The Application of the National Building Regulations,” explains Schnetler.

Construction company weathers
economic storm
Very few construction companies remained untouched by the financial hurricane that swept the globe, flattened some pillars of the economy, ripped the roofs off others and shook the shutters of everyone else left standing over the past year. The global economic climate tested the resilience of companies to maintain focus and of management to stay calm. The construction industry depends on growth and when that comes to a halt, things can get ugly. The Chief Executive Officer of NMC (Pty) Ltd., Shaun Webber, summed up the situation: “There were three aspects that affected construction companies globally. One was finding new work; the second was that delivery; and the third was that cash – clients stopped paying. We were no different. NMC lost a great deal of confirmed business.” NMC, a 30-year-old, privately owned construction company, put a diverse construction portfolio in place to help weather the storm. NMC shifted its focus from being a niche industrial contractor to becoming a construction company whose portfolio embraced civil engineering,
fenestration, flooring, construction and, even more significantly, enterprise development. According to Webber, deciding to diversify the NMC portfolio was a difficult strategic decision to make. “Why diversify when you can actually make more money doing what you were doing? But we knew that – the industry being cyclical – the cycle would come again,” says Webber. By the third quarter of 2009, NMC had retrieved more than 75 per cent of its lost business. “We had weathered the storm.” Although NMC managed to pull back much of its lost business, the economic catastrophe called for more innovations and strategic shifts by this company. NMC also decided to expand its geographic footprint into other parts of Africa and to establish the NMC Business School. The board of directors also decided to involve the entire company in a newly implemented series of feedback sessions that took place five times per year. According to Webber, the real strength of NMC is in its people, its clients and the solid, open relationships between them that the company culture endorses. “I’m very optimistic,” says Webber. “We will see through the next 12 months, and we’re poised for good growth; the potential – as a group – is set to take off. We will remain ‘the greatest little construction company’ because we want to continue to be extremely good at what we do: delivery par excellence and looking after those people who enjoy working with, and for, us.” For more information, visit www.nmc.co.za, to which full acknowledgement and thanks are given.
