Audi on Show

Dynamic dealership set to become an East London landmark Audi East London was one of the smallest Audi dealerships for new and used vehicle sales in the country at just under 250m². This changed in March 2013, when its new 4 500m² premises transformed into a fully-fledged Audi terminal dealership.


TT Group Director, Fred Whelpton believes that the uniquely designed building will become a landmark in East London and act as a permanent billboard, attracting new customers who want to experience the full premium Audi purchase and service experience. South African Architect, Amandio Castanheira of Alchemy Architects has been involved with implementing Audi’s brand design in several of the new dealerships. His firm has designed the new Audi Centres for Hatfield, Northcliff, Pinetown, Rivonia and Nelspruit, with several of the new showrooms currently under construction, including Claremont, Bloemfontein and Vereeniging to be completed by December 2013.


DEALERSHIP LAYOUT He adds that, in the conception of the terminal showroom, ‘minimum footprint with maximum efficiency’ is central to the overall design and allows all of the functional areas important to a motor dealership to be stacked one on top of the other on several floors. “The long rectangular shape of the dealership necessitates installing an expansion joint down the middle of the building, which essentially creates two different buildings next to each other acting as one building. The main section consisting of the main new vehicle showroom, offices and service reception and first floor administration conceal a basement housing the workshop and parts store. The other half of the building consists of pre-owned vehicle sales showrooms, the handover bay and coffee bar area.”



SHOWROOM IN MOTION Amandio believes dynamism, asymmetry and transparency remain central principles of Audi’s brand architecture. At first sight a honeycomb aluminium cladding forms a three dimensional façade on the exterior that creates a sense of movement as the sun moves across the sky, creating an interplay of shadows. Stepping inside, the asymmetric curves form a three-dimensional environment and are a defining characteristic of the Audi terminal. Inspired by racing tracks of the 1930s, the central curved wall sets the tone of movement and energy in the interior which extends all around the showroom, morphing into the floor and wrapping around the façade, where it cuts into the glass and creates dynamic tension,” he says. “To heighten the idea of motion, twenty-four new and preowned vehicles are displayed on the dynamically styled curve segments. Accentuating the asymmetrical look, all other operations related to vehicle presentation and to the workshop are arranged at right angles.”

‘UNDER THE SKIN’ EFFICIENCY An energy efficient building, while still catering for a comfortable experience inside the showroom, is a critical element. This has been achieved through innovation in the design, the method of construction, materials used and systems integrated ‘under the skin.’ Some intelligent innovations were integrated to regulate the interior temperature and achieve the optimum climate of 21 degrees Celsius, reducing the need for air-conditioning. “Orientation of the building and careful placement of the showrooms are the first consideration to minimise the amount of sun shining through,” explains Amandio. “The most energy efficient glass available in the country is used to block the Sun’s UV rays, reducing the bulk of the heat gain of normal clear class.” “Another innovation is the triple skin system of the façade. An air gap is created between the outer brick wall and a middle steel wall. As the sun hits the outer steel wall, hot air is contained in the air gap. The hot air builds and starts to rise, escaping through a void at the top. The air movement along the façade cools the building during the day.”

Top Priority Bidvest TopTurf brings gardens back to Durban’s cityscape Bidvest TopTurf, a unique landscaping company in the Bidvest Managed Solutions portfolio, is a multi-disciplinary Green Services company that provides quality horticultural, specialized turf and recreational solutions according to a broad scope of client requirements.


ust recently, the company made news when it completed its second rooftop garden project, one that would render the roof Mr Price Group building in Durban a greener, healthier and literally more fruitful place for staff to relax and get creative. This Durban city rooftop now lends itself as a meeting place for employees in various company divisions who would otherwise not interact with one another and provides a source of food and herbs for the company’s canteen. The decision to turn the Mr Price Group rooftop space into a garden area was encouraged by Bidvest TopTurf’s earlier work on the Priority Zone rooftop garden, a project completed for the Architectural Department of the eThekwini Municipality, a public-private partnership under the management of Drake & Scull, earlier this year.


PRIORITY ZONE Bidvest TopTurf was contracted to design and install a functional, sustainable rooftop garden as an educational platform for the production of fruit, vegetables and herbs using products that are recycled and eco-friendly. The building’s roof leant itself to a rooftop garden project and was poised to attract ever-absent wildlife back to the Durban city centre. Although the rooftop garden installation was initiated as a project for the purposes of cooling the ambient temperature of the building and for utilizing as much ‘wasted’ space as possible in the pursuit of growing vegetables to supplement for Priority Zone’s existing supply of fresh produce to charities and homeless people.



DESIGN MOTIVATION: The design of the Priority Zone rooftop garden was informed by the large number of people on the roof each day, which necessitated rendering the roof highly accessible, whilst using the space to its full potential without losing its aesthetically pleasing appeal. Water run-off was a prominent factor that fed into the project design. Geometric blocks were installed so as to split the weight of the beds, easing the pressure on the roof and the straight pathways, and to aid the flow of any excess water.

WATERPROOFING: The Priority Zone rooftop had existing waterproofing before the garden project commenced, but further drainage under the growing media was necessary. Zip-core drainage, produced by Kaytech for this specific application, as well as for vertical gardens, was applied. The drainage consists of three layers, including a dimpled sheet to encourage water run-off, a plastic mesh that creates an air gap between the dimpled layer and the bidim, which is necessary for the retention of the soil and to keep it from eroding and washing out. This product as proved to be highly effective in this application, with zero pooling occurring during December 2012, a month boasting record rainfall.



ROO F TO P GA R D E N S RAINWATER HARVESTING & IRRIGATION: Rainwater is harvested from the Priority Zone roof, as well as from neighbouring roofs, whose gutters have been tapped into and rainwater flows directly into the 4000L and 6000L tanks before passing through a sieve. The irrigation system employs the use of four key valves to hand water the fruit and vegetables and an automated pop-up irrigation system is in place to keep the lawn watered.

SOLAR & GREENHOUSES: Solar panels were installed by Solar Sun Solutions, who complemented the whole project by feeding heated water to the bathrooms and kitchens. This system not only runs the whole IT system’s power supply, but doubles up as a back-up lighting system should the regular supply trip. The system seamlessly switches over without any dip in the lighting. The greenhouses were installed by Organic Farms Group and are simple, yet functional and take weight and height considerations into account. The greenhouses are growing ‘machines’ and foster a much more regulated growing environment than the rest of the garden. The greenhouse tunnels are also irrigated from the harvested rainwater.



ROO F TO P GA R D E N S The lawn is a purely decorative aspect of the rooftop garden and brings the environment together visually and in a way that engages visitors to the rooftop. One of the first things many visitors do is kick off their shoes and walk on the grass. It’s likely that we drive or walk past lawns every day, but the novel and unusual placement of a rooftop lawn makes it exciting to experience in a tactile way. The lawn was brought in as super-sod/washed-sod and was laid in half-metre squares. Royal Blue grass was selected for its hardy and slow-growing properties. For more information, visit

PLANTS: The garden is broken down into areas, including a succulent garden, which encourages visitors to plant water-wise gardens at home, a vegetable bed, and a herb section. The seating area is centralized, offering visitors a 360Ëš view of the garden. Hanging basket plants include herbs and fragrant flowers and window boxes were planted with creepers, which will grow up and along the walls and across the overhead beams to create a lush and protected look and feel for the courtyard area. Tomatoes, cherry tomatoes and granadillas were planted alongside the creepers and other sun-loving plants included are a mix of leafy vegetables and fruits and low-maintenance succulents. Trees of 2-3 metres high, which were sourced from CJM Growers, were planted above the support pillars, which are able to accommodate their weight.

Moving beyond style and comfort Rayal Roof Tiles SA produces ceramic and porcelain tiles locally

BACKGROUND: Jiangxi Yaxing Industrial Corporation is a group company involved in textiles production, real estate development and sales, building porcelain equipment sales, and installation and industrial trade. Its subsidiaries include Jiangxi Yaxing (SA) Trading (Pty) Ltd. and all of its product offerings are reliable in quality, fresh in colour and elegant in taste, becoming very popular in South Africa, East Europe, and Middle Asia and other regions. With a diversification strategy worldwide and investment support, Jiangxi Yaxing built a ceramic and porcelain production line in Bronkhorstspruit, east of Pretoria, making this the first of its kind on the African continent. The factory investment totals more than R300mil and was built in 2011 with the first production line commissioned in May 2013. The company plans to install a total of four production lines in the next three years with an ultimate planned capacity of more than 1 800 tons per day in ceramic and porcelain manufacturing.


Says Alwyn Cronjé Jnr., National Sales Manager for Rayal, “Market research indicated that although the Tuscan look and feel has dominated roof design for many years, the new generation of South African architects and homeowners are ready for new, innovative and creative ideas that will stretch the imagination beyond style and comfort in roof covering materials and design.” He continues, “This product has proven itself in Europe and the East alike with its quality, fresh colours, porcelain finish and affordability, and is now manufactured by Rayal in South Africa. The product has already brought excitement to smaller roof applications, specifically for the entry-level and low-cost residential markets.” Cronjé Jnr. continues to say that the South African manufactured product gives character to our diverse culture, charm and definition to the sharpness of these smaller roofs.






“Moving beyond Style and Comfort”

FIRING AT 1100o AND OFFERING TWO FINISHES GLAZED MATT TILES The popularity of this type of tile grew rapidly around the world following technology evolution in single firing whereby we obtained high aesthetic value tiles.

GLAZED GLOSS TILES Glazed porcelain tiles appeared in the second half of the 1990s, which contributed to the advancement in the overall quality of porcelain production. These proved superior to the normal single fired tiles which have higher porosity, lower strength and lower firing temperature. A key practical implication is that the low porosity of porcelain tiles makes them frost resistant. In addition, the higher quality body composition and resultant surface enables the use of a minimum amount of glaze (enough to close surface pores).

FIRING AT MORE THAN 1100˚C, OFFERING TWO FINISHES: Nowadays, porcelain tiles are more popular because of their unique advantages. Porcelain tiles are fully vitrified, glazed or unglazed and can be made using a white or coloured ceramic body composed of a mix of light colour clays. They are shaped by pressing a powdered body and then fired in a high-tech controlled environment.

GLAZED MATT AND GLAZED GLOSS TILES: “Glazed porcelain tiles appeared in the second half of the 1990s and these contributed to the advancement of the overall quality of porcelain production today,” says Cronjé. The glazed tile as alternative to the matt finish can be polished to enhance the quality and aesthetics. Cronjé adds, “A key practical implication is that the low porosity of porcelain tiles makes them frost resistant. In addition, the higher quality body composition and resultant surface enables the use of a minimum amount of glaze (enough to close surface pores).”

RAYAL ROOF TILE ADVANTAGES: • No efflorescence • Lightweight, saving up to 40% on transport costs • Cost-effective • High mechanical strength • Very good frost resistance • Can be matt or gloss glazed • Colour fast • Good abrasion resistance The lightweight properties of the Rayal roof tile also helps to minimize transport costs, that have become a significant contributor to overall costs, and its colour fast properties also ensure that maintenance is minimal over time. The under-structure (support structure) can also help reduce design and material cost significantly, making Rayal one of the most optimized roof designs available today.

ITC-SA becomes a Professional Body The Insitute for Timber Construction (ITC-SA) has been awarded Professional Recognition by the Board of the South African Qualifications Authority (SAQA).


his was after a comprehensive process of evaluation by the SAQA Board to confirm that the ITC-SA meets the set Policy and Recognition Criteria as part of the SAQA mandate, and which is, inter alia, to further develop and implement the National Qualifications Framework (NQF) as per Section 13(1)(i) of the NQF Act, Act 67 of 2008. This criteria, with which the ITC-SA had to comply, and which are set as a minimum requirement, were workshopped and developed by SAQA after extensive consultation with various stakeholders, including statutory and non-statutory professional bodies, the Quality Councils (Council on Higher Education, General and Further Education and Training Council (Umalusi) and the Quality Council for Trades and Occupations), as well as providers of education and training. This means that the ITC has now been assigned the authority to formally monitor and regulate construction standards in the timber roof truss industry. Mr. Lyndsay Cotton, Chairperson of the ITC-SA says, “We are thrilled about this recent development. The ITC-SA offers an invaluable service to the built environment and consumers, for


the purpose of regulating the timber roof truss market, and is an organization worthy of accreditation by SAQA, to whom we are grateful for their support and assistance.�

WHAT DOES THIS MEAN AND HOW WILL THE BUILT ENVIRONMENT AND THE CONSUMER AT LARGE BENEFIT FROM THIS? The ITC-SA as a Professional Body, now registered with SAQA, has the authority to confer a professional designation on an individual in the form of a title, status and/or registration number. This professional designation indicates registration of the individual with the ITC-SA, and the right to practice in the particular field of expertise governed by the ITC-SA. For the consumer at large, the recognition of the ITC-SA as a Professional Body will strengthen social responsiveness and accountability within the designations, and will promote pride in association for all professions.



Lyndsay Cotton, Chairperson of the ITC-SA.

WHAT WAS REQUIRED FOR THE ITC-SA TO BE RECOGNISED? The ITC-SA as an applicant Professional Body (and who will represent and/or regulate the timber roof truss industry) was accredited by SAQA after confirmation that the criteria below had been met: • Had to be a legally constituted entity with the necessary human and financial resources to undertake its functions, governed either by a statute, charter or a constitution and be compliant with and adhere to good corporate governance practices; • Must be able to demonstrate protection of public interests in relation to services provided by its members and the associated risks involved; • Must be able to develop, award, monitor and revoke its professional designations in terms of its own rules, legislation and/or international conventions; • Must be able to submit a list of members in the form acceptable to SAQA; • Must have set criteria for promoting and monitoring continuing professional development (CPD) for its members to meet the relevant professional designation requirements; • Must have a published code of conduct and operate a mechanism for the reporting and investigating of members who are alleged to have contravened the code; • Must not apply unfair exclusionary practices in terms of membership admission to the body or when recognising education or training providers; • Must be able to provide information related to career advice on members to SAQA.


THE ITC-SA, IN MEETING THE POLICY AND CRITERIA FOR THE RECOGNITION OF PROFESSIONAL BODIES, WILL NOW, INTER ALIA: • Recognise suitable education and training providers and be involved in the curriculation of learning programs offered by education and training providers; • Set and administer its own Board examinations; • Register its professional designations on the NQF in accordance with the SAQA policy and criteria for registering a professional designation; • Meet the South African requirements, as outlined in the policy and criteria for recognising a Professional Body and registering a professional designation for the purposes of the NQF Act, including the data requirements. Foremost, the ITC-SA (as a main driver) will ensure that perceptions of exclusionary practices do not occur. Fred Wagenaar, the Executive Officer of the ITC-SA, says, “The ITC-SA’s recognition as a professional body by SAQA represents a learning curve for the Institute, and one that has brought with it a natural progression towards its sustained growth.” Cotton concludes, “We have toiled the last couple of years for this recognition and look forward to being able to provide a professional service to our professionally recognised members and consumers at large.”

MiTek roof structure for prestigious Boardwalk Casino Hotel The imposing and very large roof structure for the Port Elizabeth Boardwalk Casino Hotel with its steep roof, numerous dormer windows and turret structures, was provided by the Buco Hardware Buildware Uitenhage, a long established MiTek licensed supplier.


lthough the roof structure was very large with spans of 20m and a roof pitch of 45 degrees, the whole roof was made of pre-fabricated nail-plated timber trusses utilizing MiTek design software and connector plates. In certain instances the roof structure was made up of three tiered trusses stacked on top of each other.




The project duration was just over eight months, including interruptions of about six weeks of rain. A daily delivery of materials ensured uninterrupted continuity, whilst cranes lifted the trusses into position. It is therefore no surprise that Buco Uitenhage completed this project within the allocated time frame. MiTek Industries South Africa (Pty) Ltd is very proud to be associated with the Buco Group and this prestigious project.

FOR MORE INFORMATION, CONTACT: The timber structure with a roof area of over 6500m² required some 168m³ of timber, which would equate to about 81 tons with a further 2.5 tons of nail-plates and hangers making up the supply price of R2.3 million excl. sheeting, erection and VAT.

MiTek Industries South Africa (Pty) Ltd (t) 011 237 8700 (e) (w)

Utilizing the powerful MiTek 20/20 design software, Buco Uitenhage was able to design all aspects of this roof structure including the complex dormers and turret roofs. Final working drawings were exported directly from the software and all designs, as well as the completed roof structure, were checked by the MiTek engineers.

LCP Roofing (Pty) Ltd.

Leaders in Roof Truss Technology A clear vision, backed by definite plans, gives you a tremendous feeling of confidence and personal power. - Brian Tracy

“The vision of a multifunctional team at LCP Roofing has become a reality,” says Andri Pretorius, Managing and Operational Director of LCP Roofing, a Pretoria East-based ITC-SA ‘A’-graded fabricator and erector of timber roof trusses. “With the vision firmly entrenched in our minds, all we needed was to put our clearly defined plan into action and in June 2013 our first multifunctional carpenter and sheeting team sprang into action. I knew it was going to work,” says Pretorius, “but little did I realise just how well.” “The South African construction landscape is largely plagued by poorly trained and inefficient sub-contracting teams and unless these teams are trained and mentored by the very contractors that utilise their services on a daily basis, their true potential will never be realised,” adds Lyndsay Cotton, General Manager of the company. “Unfortunately, it is the client who suffers the consequences of inferior quality of work delivered and we have made it our mission to train and mentor our emerging contractors, something that has been a success as attested to by the growth in skills achieved by these sole proprietor business units.” Cotton adds that the company also needed to grow a skill set from within, so as to achieve the vision of a quality driven product and of service excellence that the industry has come to expect from LCP Roofing.


“I have received more calls complimenting us on our competence and the quality of our work in the last three months since our in-house teams commenced operations, than in the last three years,” says Pretorius. “Now that gives one a tremendous feeling of confidence and personal power.”

TR U S S E S LCP Roofing has invested in a Mercedes Sprinter panel van, as well as a Sprinter 16-seater bus to transport their erectors and sheeters to site and back safely.

THE RIGHT TOOLS FOR THE JOB Empowering an in-house team, means facilitating and enhancing their skill set from all perspectives. LCP Roofing has invested in a Mercedes Sprinter panel van, as well as a Sprinter 16-seater bus to transport their erectors and sheeters to site and back safely, efficiently, and professionally, with a fully outfitted mobile workshop fitted onto a custom-built trailer. Commenting on this investment, Pretorius says, “If we were going to do it, we were going to do it the right way. If we are to expect top class workmanship from our staff, it is imperative that we kit them out to do the best job possible.” Another part of the carefully laid out expansion plan was to reduce their dependence on inefficient generators which guzzle fuel and belch smoke. A generator running all day could easily use R2 000’s worth of fuel in a month, not to mention the noise generated. So, whilst the LCP Roofing team still uses generators to power heavy duty equipment, they have gone ‘cordless.’ “Included in our ‘arsenal’ is the very versatile and excellent range of Bosch 18V cordless tools, which includes four drills, two circular saws, a jigsaw, a reciprocating saw and an angle grinder. Although we are armed with 10 batteries, the carpentry team seldom uses more than 4 batteries during a full day’s work,” says LCP Roofing Site Manager, Wilhelm Kotze, who ensures that the teams are supervised and efficiently managed, adding, “These batteries are then charged overnight back at the factory. Now that we have proved the reliability and versatility of the cordless system, we are investigating installing solar panels to charge the batteries.” “LCP Roofing metal sheeters have also been well equipped and we avoid the use of angle grinders unless absolutely necessary,” says Kotze. “Most sheeting suppliers strongly discourage the use of grinders as the resultant damage to sheeting voids their product warranties. We employ the use of the Makita 4131 metal cutter and after much research, we have imported mechanical snips (also cordless and powered by Makita) from Australia, which have proved invaluable in all the scribing required on a sheeted roof. In competent hands these snips are almost four times faster than an angle grinder and leave a clean and completely burr-free cut.”

There are presently four erector categories and only erectors in category ‘A’ (high risk) may erect roof structures for public buildings, laminated timber structures, spans larger than 10m, scissor trusses greater than 5m, attics, dormers, piggyback trusses, complex industrial and commercial buildings and complex hip systems. With this accreditation, LCP Roofing offers their clients confidence that their structures are erected in a competent and professional manner and, in keeping with the rules of our now professional body, the ITC-SA.

SAFETY The factory and site team representatives have undergone first-aid training and the company currently has six trained individuals across various levels in the company. All production and site staff are issued with all the required safety equipment which includes footwear, headgear, eye and ear protection where necessary, overalls, reflective jackets and harnesses. On the smaller residential projects, safety is managed in-house and larger commercial sites are supervised by appointed external safety inspectors and auditors.

INSPIRED BY TECHNOLOGY, DRIVEN BY QUALITY All timber structures are checked by independent, competent roof inspectors to ensure that the structures are erected according to the design intent. Aside from these legally required inspections, LCP Roofing employs an internal quality policy where all timber structures, tiled roofs and sheeted roofs are checked according to internal quality guidelines and these checks include various aspects to ensure aesthetic acceptability, water-tightness and client acceptance post-roof construction phase.

Insulate for climate and cost control With increasing pressure on South Africa's electricity supply driving up costs, smart homeowners are looking for opportunities to keep their property warm in winter and cool in summer without heaters or air conditioners. The answer to this challenge lies in effective insulation, says Willem Grové, Marketing Manager at Coverland, which substantially increases the energy efficiency of a building.

"By controlling the climate of the home with an effective insulation solution, the necessity to heat or cool using electricity is greatly reduced," he notes. "Simply put, that means saving money by using less electricity and thereby doing your bit to preserve the environment." RadenShield™ Scientific Layering System by Coverland is a super reflective silver aluminium barrier that creates a shield against the sun's harsh radiant heat rays. The Agrémentcertified product range can be used in both galvanised sheet steel cladding and concrete roof tile structures for residential, commercial and industrial use. In addition, all RadenShield™ products act as a barrier against dust invasion and water ingression. Coverland RadenShield™ is manufactured from non-woven polypropylene spun bond membrane that is laminated to highly reflective aluminium sheets, resulting in a product with highperforming insulating properties.


The aluminium foil has two interesting physical properties; it is a good heat reflector and a bad heat radiator. The membrane is UV resistant, non-toxic along with being flame retardant ensuring it complies with SANS Fire Protocol. There are three different types of heat transfer, namely conduction (transfer of heat within materials or between materials in contact), convection (transfer of heat by motion) and thermal radiation (transfer of heat by electro-magnetic waves). Thermal radiation is responsible for between 90% and 93% of radiant heat that is transferred in a downward flow from the roof, and up to 80% of the heat transfer through side walls of the building. In order to be classed as a radiant barrier, RadenShield™ reflects between 95% and 97% of all radiant energy. This results in an emissivity value of between 0.05 and 0.03.



"Using RadenShield™ will result in a cooler home or work environment in summer and will act as a barrier to retain warmth in winter." Grové adds that a building with RadenShield™ installed prevents heat from entering through the roof in summer, keeping the house up to 10°C cooler. "With RadenShield™ one third less heat energy enters the roof," he confirms. It also retains heat during winter, which can save up to R2 500 per annum.* The RadenShield™ Scientific Layering System is easy to install, as it is sturdy enough not to flap around in the wind, yet flexible enough for quick and easy spanning. The unique bonding process prevents delamination and tearing, ensuring a longlasting, firm radiant barrier that doesn't deteriorate under tough conditions.

Radenshield™ Industrial is similar to the double sided product, but slightly thicker with a reinforcing scrim for added strength making it the ideal solution for factories and warehouses. "RadenShield™ ClimaGuard, a DIY solution, can be retrofitted to pitched roofs. This allows the homeowner to easily fit an insulation barrier to the existing roof structure. The result is an opportunity to reduce electricity accounts while benefiting from a comfortable home all year round." Coverland products are available nationwide. *(Scientifically tested by the Monier Technical Centre Germany. Based on a 90m² house at a regulated temperature of 22°C). For more information, visit

Available in three different variants, Grové says RadenShield™ Single-Sided and Double-Sided is designed for residential homes and commercial buildings constructed with pitched roofs.

ften roofing fasteners are the cause of problems on a roof, especially when drive nails have been used to fix roof sheeting to timber purlins. Sometimes the problems already occur during the roofing installation process. When the nails are driven through the roof sheeting, it often leads to ponding, as the rib of the sheeting is dented. This leads to an area where rain and debris collect, which causes premature corrosion. As the nails are driven into the purlins, the timber often splits, especially when the nails are not driven in the centre of the purlin. The result is that the sheeting is not fixed down properly and could be easily blown off in windy conditions. To control the depth to which the nails are driven in is difficult to control especially when unskilled labour is used. If the nails are not driven deep enough, leaking will occur between the washer on the nail and the sheeting. If the nails are over driven, ponding will occur with the same results as described earlier.

Another problem that occurs when drive nails are used is caused by the expansion and contraction of the roof sheeting. As the roof sheet expands when it warms up during the day and contracts at night when it cools down the drive nails are pushed to and fro on a daily basis. The grain of the wooden purlins, which was forced down when the drive nail was hammered in, tends to move back to its original position and this combined process pushes the nail out of the hole. Depending on the length of the roof sheets, this normally occurs between 3 – 5 years. Once the loose drive nails have been detected the nails are usually driven back into the hole, only to work loose again, but this time in a very short space of time. The next process that usually follows is to remove the drive nails and to replace them with longer nails. The same process then repeats itself and is often accompanied with large amounts of sealants; membranes and various kinds of patchwork – all of which are in vain.


If the loose drive nails are not detected timeously, rain will penetrate the roof and run down the drive nails onto and into the timber which will lead to rotting of the purlins.

Corroded drive nails with perished washers. An effective way to solve the problem is by replacing the drive nails with 8mm diameter coach screws. These screws have a coarse thread that will cut a thread into the timber rather than damaging the grain of the wood. As the coach screws are bigger in diameter than the drive nails, they will cut into the timber from the top to the bottom of the existing hole. If the purlin thickness allows it, coach screws longer than the existing drive nails should be used. In order to overcome the problems of ponding and oversized holes in the sheeting caused by the drive nails, saddle washers or curved washers can be used on IBR and corrugated roof sheeting.


Saddle washer. It is worth mentioning that not a single one of the major roof sheeting manufacturers recommends or endorses the use of drive nails to fix roof sheeting to timber purlins. Of course, prevention is better than cure and all the problems caused by using drive nails can be overcome if the correct fasteners are used to start off with. Self drilling screws with a Type 17 point are specifically designed to fix roof sheeting to timber purlins. The cut point on the fasteners will drill a hole through the roof sheeting without denting the sheeting. The point will also penetrate the timber, enabling the screw thread to cut into the timber. The coarse thread on the Type 17 screws is purposely designed to offer the highest pull-out values possible. In keeping with SANS 1273 – 2009 specifications, Type 17 screws are available in electroplated Class 2, mechanically plated Class 3 and 4 finishes, as well as stainless steel Class 5. To determine the correct length of Type 17 fastener, add the profile height of the sheeting to the compressed thickness of any insulation between the roof sheeting and the purlin and then add 35mm for penetration into the timber. This will ensure a proper fix with good pull-out values.

Type 17 point.

Type 17 fastener. Type 17 fasteners are installed using electric or cordless screwdrivers with a depth gauge. Using the correct tools for the installation of the screws will ensure that each and every fastener is driven to the correct depth ensuring a watertight and secure fixing. Selecting the right fasteners for a roof will ensure that the life span of the fasteners will match that of the roof sheeting and will reduce maintenance and repair costs of a roof. This will free up some money to pay for that gym contract‌ Article supplied by Reitze Hylkema of Kare Industrial Suppliers.

Protecting the SA Steel

Construction Industry from Imports The Southern African Institute of Steel Construction (SAISC) recently hosted a discussion on the subject of the impact steel imports are having and could potentially have on South Africa’s fabrication industry.


resented by Kobus de Beer, SAISC Industry Development Executive, the presentation highlighted the reasons behind this phenomenon and the possible steps to mitigate its impact. Various issues relating to the impact of these imports and the subsequent need for protection of the steel industry were discussed.

ECONOMY OF STEEL IMPORTS: South Africa is a successful exporter of structural steel, so the industry is reasonably competitive. The country boasts a robust steel fabrication industry, which produces 720 000 tons of steel per year, and employs a total of 111 720 people (72 720 to do fabrication work and 39 000 employed through construction). Furthermore, a medium-sized steel fabrication company can produce up to 6 000 tons of steel per year, and represents employment for approximately 600 people for that year. This equates to 100 decent jobs, permanent and paid to schedule for one year, per 1000 tons of produced steel. The steel industry is also an economic multiplier and statistics show that a R1-billion structural steel project can potentially initiate economic activity in various areas to the value of R1.43billion. The table below gives a breakdown of the spread of the benefits:

Table 1.1 Economic activity in R1-billion structural steel project. COSTS:

Community and social



Wholesale and retail



Transport and storage



All other sectors



Rest to taxman


The general opinion on the state of the local steel fabrication industry in 2012 was that if South Africa was still producing steel for the African market, as well as still exporting, then the steel industry should still be active and prices and quality good. However, a closer look at the impact of imports paints a very different picture. Table 1.2 illustrates the recent structural steelwork projects using imported steel, and the number of local jobs lost due to these imports and why protection is really necessary.

Corruption and price fixing in South Africa have also played a part in increased imports and have undermined South Africa’s credibility as a sound economy with which to do business.

MITIGATION: There is much the steel industry can do to halt the steady flow of imports. A start would be for the local industry to take a holistic approach to client needs and to offer solutions (not just the steelwork), to be both cost- and service-competitive, and equip staff with the necessary skills to provide good service.

Kobus de Beer, SAISC Industry Development Executive. In addition to these ‘decent’ job losses, the country also loses through the impact of imports on the economic multiplier. In other words, if local contractors spend R1-billion per year on imported fabricated steelwork for projects, representing 50 000 tons of steel per annum, it requires R1-billion cash outflow. Furthermore, as shown in table 1.1, local contractors also lose R1.43-billion in economic activity, as well as 25% of taxes (after 14% VAT is earned). What is also alarming is the loss of 5 050 jobs for that year, especially in light of South Africa’s unemployment rate which, according to Financial Mail, Business Day, is currently 25.6%. This equates to 7.4-million people without work (up from 4.6-million in the previous quarter).1 All of these figures show that importing does not make sound economic sense, and the fact that there is a general lack of awareness of the consequences of imports doesn’t help matters much. Most companies are also set up to import, and are lured in by the ‘attractive’ initial prices. Companies tend to follow what their competitors do, and this includes importing. Overall there is also the perception that South Africa is expensive, and that local steel companies do not have capacity, or sufficiently skilled staff.

REASONS FOR INCREASED IMPORTATION: While China’s labour costs two-thirds of the price of South Africa’s, China typically offers their employees benefits which South Africa does not. Some benefits include being able to live on the premises, two meals per day and schooling available on the premises for the labourers’ children to attend. Workshops in China are very similar to South Africa’s, but employees work a six-day week, and while they are owed 14 days’ annual leave, this includes China’s seven public holidays, which means that their annual leave is considerably shorter than South African employees’. Most steel mills in China are governmentsponsored, which reduces their overheads tremendously. The shortage of skills in the local industry, especially in design and draughtsmanship, is of concern. There is limited on-thejob training for engineers and draughtsmen taking place in South Africa anymore and new technology can offer up its own challenges. There is also vast discrepancy in qualification standards between China and South Africa, where in China a supervisor could be a qualified engineer, while in South Africa a supervisor is likely to only be a qualified school-leaver.


The steel industry also needs to be made aware of the disadvantages of imports, such as the displacement of South African jobs, delivery or quality of the steelwork, misunderstandings caused by language barriers, which could potentially have a knock-on effect in that late order changes can be challenging, and there could be legal disputes (which, due to foreign laws, can make it difficult to lay claims), and ultimately, the increased costs of resulting quality assurance and rectification. Ways to build on the state of the local steel fabrication industry include creating awareness, providing training about the steel industry, auditing the origins of imported steelwork and creating a benchmark for accurate cost comparisons. Companies could also build on Eskom’s commitment to localization. In addition, company newsletters highlighting successes (using local steel) and publicising any unused capacity could also be distributed. The SAISC is already taking action to protect the steel industry from imports by taking an aggressive approach in promoting competitiveness amongst South African steel companies to export, and challenge foreign projects. The Institute is also exposing illegal importing activities to the DTI and SARS, and is applying for the implementation of dumping, designation and duties. The SAISC is also continuously generating publicity for the steel industry in the form of articles and interviews. However, even while the SAISC is doing what it can to protect the local steel fabrication industry, in the last three years, well over 100 000 tons of steel were imported, resulting in a loss of 7650 decent jobs – these were well paid permanent jobs, where capital investments in workshops, etc. have already been made, where people were fully equipped and skilled – a sobering reminder, not only of an industry at risk, but of the uncertain livelihoods of many ordinary South Africans. Maintaining existing jobs must surely be our highest priority.

Installation issues should not impede the deployment of solar PV systems Roof-mounted solar photovoltaic (PV) panels can change the power dynamic of South Africa by supplying efficient, green energy for almost any use. They are, however, a new option for many South African companies, many of which may now be reasonably wary of installing them following Carte Blanche's exposé of the poor installations of rooftop solar geysers that resulted in unserviceable solutions. By Bernhard Suchland, Managing Director at Schletter South Africa


In the case of the Carte Blanche exposé in June this year, there were numerous installation problems that resulted in leaky pipes, brackets that weren’t attached to roofs and internal, structural damage to homes.

Installation is as crucial as getting the right product. Solar solutions will fare better in the long term if they are easier to install and are suitable for a wide range of structures, since solar panels can actually be mounted to commercial and residential roofs, carports, car parkades and even vertically to building façades, depending on the building’s orientation.

At this early stage of solar deployment in South Africa, considering Eskom’s preferential rebate programmes and the Department of Energy’s programmes to deploy alternative energy plants, it is crucial for the industry not to gain a bad reputation that would take years, if not decades, to rectify.

n the case uncovered by Carte Blanche, the problem lies not so much with the quality of the products used, but rather with the installation process.

The industry is divided into companies that supply the solar panels, those that provide the mounting systems and those that install the systems.




With the maturity of the offshore solar PV industry, many of the current suppliers are from abroad, but they are investing in a South African solar PV industry by establishing local manufacturing, working with local manufacturers, and training local installers. The benefit of this approach is that decades of experience are passed on very quickly to local businesses, which means they can quickly rival the quality of their international counterparts. The solar mounting equipment manufactured locally can be as good as that produced in Germany for example, because it can be done according to ISO 9001:2000. The ISO standard specifies requirements for a quality management system.

As government is learning through issues such as the solar geyser tender, it is important to find suppliers with good quality systems that are installed by professionals. This does not have to be at the cost of local businesses, local manufacturing and BBBEE. Local businesses with good reputations and years of experience have invested in these systems. They range from local electricians to construction services, materials and infrastructure investment groups, engineering businesses and even architects.

Another standard, DIN 18.800 (DIN essentially being Germanyâ&#x20AC;&#x2122;s equivalent of ISO), governs the quality of welds used to manufacture the mounting brackets and platforms. Tests are also conducted on the designs of the solutions to ensure they can withstand atmospheric, particularly wind, conditions by using sophisticated and expensive wind tunnels. If the manufacturing processes, the quality of the materials used, and the certification of qualified installers are tallied, the net result should be systems that are guaranteed for more than a decade, which should be the minimum time these solutions should take to be productive. The challenge is to find the right solution and to ask the right questions about quality.

The SolTech glass roof tile Stylish, strong and effective SolTech’s glass roof tile is designed as a part of SolTech Energy’s solar energy system and also does the job of a traditional roof tile, protecting the building. The tile is manufactured from highly transparent glass with low iron oxide content and has a double bend, a design feature that enables SolTech tiles to be fitted together with various complementary products made for traditional concrete tiles, such as specific fittings, seals, gaskets, etc.

APPEARANCE: The low level of iron oxide gives the glass tile a light silver or grey tone, influenced by the colour of the underlying material (absorber) and the sky when installed. The surface of the SolTech tile is smooth and corresponds to that of glazed tiles.

AESTHETIC SOLAR ENERGY WITH SOLTECH SIGMA AND SOLTECH POWER: SolTech Sigma and Power represents an efficient, tidy and simple solar energy system for residential, as well as commercial applications. With SolTech’s thermal and electricity generating absorbers, which are specially developed for the SolTech glass roof tile, installation is simple and overall system efficiency is higher. SolTech’s specially developed liquid-based and electricity generating absorber modules that harvest energy from the sun are installed underneath the glass roof tiles. The modules are patented and have integrated carrying batten for maximized absorber surface. The modules are interconnected on the roof to form a complete solar energy system. Generated thermal solar energy ends up in a specific storage tank that is connected to the building’s central heating system, or connected to the grid if electricity generating and configured in such way that all the energy the sun provides is used first. When not sufficient for the overall energy needs, the central heating system and/or normal electricity supply provides the difference.



FLEXIBILITY: The thermal system can be integrated with all currently known heating systems, such as district heating, geothermal heating, air-towater heat pumps, pellets, wood, oil or electric boiler. The greatest amount of energy from the sun is naturally generated during summer when the sun shines the most. On wintery days during late autumn and spring when energy is needed the most, a considerable amount of thermal energy and or electricity is generated. The reason for this is the systemâ&#x20AC;&#x2122;s overall effectiveness in combination with the use of a large absorption area of the roof. For more information, visit




McDonald’s sees value of Light Steel Frame Building McDonald’s South Africa is changing the way it builds its restaurants and has embarked on rolling out sustainable light steel frame building (LSFB) restaurants across the country. This is according to Greg Solomon, McDonald’s South Africa’s managing director.

McDonald’s opened its first steel frame restaurant in Goodwood, Cape Town on 29 June 2013, making it the first LSF informal ‘eating-out’ restaurant of this kind in South Africa.


cDonald’s opened its first steel frame restaurant in Goodwood, Cape Town on 29 June 2013, making it the first LSF informal ‘eating-out’ restaurant of this kind in South Africa.

On top of this, McDonald’s was able to cut back the construction period required, opening the outlet four months earlier than if more traditional building methods had been used.

“We will continue to improve, evolve and pioneer,” says Solomon. “The new restaurants are built using light steel frames (LSF), energy efficient cladding and insulation systems. This decision stems from our philosophy to support sustainable building methods as far as design, energy efficiency and the optimal use of natural light are concerned,” he says.

One of the main advantages of LSFB is that McDonald’s restaurants built in this fashion will cool down and warm up faster than with conventional buildings, increasing the comfort levels of its customers.

By using LSFB on this building, material wastage was reduced by 30%, transport costs by 80% and the carbon footprint was significantly reduced.


John Barnard, Southern African Light Steel Frame Building Association (SASFA) director, says "LSFB is definitely much more energy efficient than more traditional construction methods – both with regard to the embodied energy of the materials and components, as well as operational energy relating to heating and cooling of the building over its design life."



“McDonalds coming soon.” None of the locals could know how very soon it was going to be! "A recent research project carried out by the CSIR indicated that an LSF building will require less than half of the energy needed to heat and cool a masonry residential building to comfortable internal temperatures,” Barnard says.

5 days later on 23 March.

The Silverline Group, a SASFA member, built the McDonald’s LSF building in Goodwood, Cape Town. After careful planning, they started on site in mid-March 2013. Project manager and co-owner of the Silverline Group franchise, Robbie Meyer, who had previous experience with LSFB in the USA, knew the benefit of detailed planning and meticulous design and he was able to optimize the light steel structure to save costs and speed up construction. After casting the concrete for the foundations and then the lower floor, the wall frames and floor joists were erected and the first floor was completed in four weeks. The wall cladding was then installed: fibre cement board on the outside, with glass-wool insulation in the wall cavities, followed by 15mm fire resistant gypsum board on the inside. While internal walls were being clad, steel sheeting was installed on the first floor to act as shuttering for the in-situ cast lightweight concrete floor.

7 April: External cladding is progressing on schedule.




14 May: Shell of the building almost completed, ready for finishing. Silverline completed the entire shell of the building, including internal walls and exterior painting in a mere two months. Road works and the installation of kitchen equipment took a further month, to give a total construction period of only three months! “A comparable double-storey building using traditional construction methods would have taken at least seven months, says Charl van Zyl, managing director of the Silverline Group. “Moreover, the project ran very smoothly indeed. We actually enjoyed the process!” At the official opening of the building McDonald’s said that they were astounded by the speed of construction, and were very satisfied with the quality of the finishes. Even before this project was fully completed, Silverline Group started the next McDonald’s outlet in Silver Lakes, Pretoria, using a similar floor plan and structure. They are again planning to finish the project in two months, and may even shave a further week off the construction time! Barnard says that the speed of construction, while still maintaining quality, is one of the biggest factors in the meteoric growth of the LSFB method in South Africa. “The lightweight steel frame goes up quickly and once it is in place you can enclose the building.


That means that internal finishes, such as partitions, ceiling grids, tiling and painting, as well as the installation of services, can start sooner,” Barnard says. He adds that the method also saves time because it allows different disciplines to work concurrently. “It is not necessary to wait for a completed façade before finalising accurate measurements for windows, for example. Window apertures can be agreed upon with the glass and aluminium contractor, even before the light steel frame walling is installed, since the system is extremely accurate. With lightweight steel one can work to a tolerance of +-5mm,” Barnard explains. McDonald’s has invested in many sustainability measures in its restaurants over the past two years, which have included building design, making sure that natural solar light and heat complement a minimum air-conditioning design, which is part of a programme Solomon refers to as ‘Project Green and Growing.’ This visionary programme targets a 20% saving in water consumption, a 20% saving on electricity consumption, 20% saving on costs and 20% saving on construction time as the brand continues on its strong growth path. “It is our responsibility to lead in this way as a big corporate, and we understand the importance of sustainable business practices to minimise our impact on the environment. We are very excited to roll out these new LSF restaurants,” he concluded.

Springtime sealing

Butyl Tape does much, much moreâ&#x20AC;Ś Butyl Tape in the roofing industry has mostly been associated with being a lap seal. This is unfortunate, as Butyl Tape, in various widths and thicknesses has a multitude of sealing uses, not only for roofing, but for guttering, flashings, ventilation, as well as repairing and sealing sections of leaking roofing sheets without having to lift up or replace the offending sheets.

Lap Seal

Skylights Seal

Ventilation Seal

HOW TO REPAIR A ROOFING SHEET WITHOUT REMOVING OR LIFTING: Make sure the surface is free from moisture, oil and anything that could prevent the Butyl Tape from bonding. Apply the tape over the joins and press into place. Make sure the tape is secure and that there are no areas where the tape is lifting or out of place.


Butyl Tape needs no mixing or curing and the longer it remains on the sheeting, the better it sticks. One can therefore paint it immediately with most conventional painting methods and look forward to a roof that will be sealed for many years to come.

Longspan Gutters

The benefits of seamless aluminium gutters Gutters from Longspan Gutters are roll-formed on site to precise lengths through gutter machines that are housed in mobile factory units.


he roll-forming process is fast, efficient and hassle-free and the resultant product is guaranteed not to fade, leak or rust. The aluminium coating formulation has been selected to provide optimum qualities of film hardness, flexibility, light-fastness and resistance to weathering and chalking.


Longspan Gutters incorporate the use of environmentally friendly, recyclable aluminium products in the manufacture, distribution and installation of their water-efficient rainwater products and any waste material generated from work sites is carefully removed and disposed of through environmentally responsible practices. Aluminium is 100% recyclable.

Due to atmospheric conditions, aluminium gutters are expected to expand and contract, which may cause the silicone sealant to shift over time. Should minor leaks occur at corner mitres, end caps or butt-joins, it is advisable to contact the supplier for a quote on removing and re-applying the silicone sealant.


Clean out debris from gutters and downpipes regularly by using a hosepipe with water, wipe surfaces clean with a soft cloth and a light soapy solution, then wipe dry.

Eco-Insulation Cracks the Nod Launched in 2006, the Eco-Insulation brand is gaining momentum and recognition.


oming from right across the country, the Eco-Insulation mailbox and consumer activist sites, including Hello Peter, have been receiving positive comments from satisfied clients in both the domestic retrofit market and the housing development market. Launched in 2006 as a human-friendlier alternative to many of the popular insulations at that time, Eco-Insulation has made serious inroads into meeting the needs of the client looking for eco-friendly, safe to handle, safe to live with and energy efficient insulation. Official bodies or industry associations have also taken note of Eco-Insulation’s efforts, starting with the SA Productivity Award the company received in the Western Cape shortly after its inception, due in large to the urgent sense of purpose and importance that the company attached to qualifying for SABS certifications. Thereafter came the excellence accolade the company received during 2008 when it was granted the ‘Energy Efficiency Company of the Year Excellence Award’ by the Southern African Energy Efficiency Association. More recently, the company received its PCC (Product Compliance Certificate) from the Thermal Insulation Association of SA, essential when specifying insulation for a project in accordance with SANS 10400-XA. Eco-Insulation’s general manager explains, “The PCC can be used along with the SANS 1381-6; 2011 certificate when confirming compliance for customers who demand assurance that the use of our product will be acceptable to risk managers and underwriters, as well as to green building energy saving compliance requirements.

Eco-Insulation in situ – a recently completed retrofit.

It is relevant to point out that certain other popular brands of insulation on the South African market are neither certified to the SANS 1381, nor do they possess a PCC, nor are they listed on the TIASA Fire Register. Hence, in the event of an incident such customers may not be covered through their insurance when using these products.” However, the proof of Eco-Insulation’s claims is very much in the reaction of its customers. “Many thanks for an extremely well-executed and professional service from your Installation team. We would like to ask that you extend our thanks to them, and also our appreciation of the exceptional professionalism on-site, and their timeous, neat and professional installation. They are gold in your hands. Thanks again.” – A satisfied retrofit client, July 2013. Eco-Insulation sees its success as being attributable to its dual focus on quality and on people. “Our dedication to quality is demonstrated by the awards we have received and our commitment to people and the environment that they live in is demonstrated by the time and trouble that they take in saying thank you and by the recognition we have received in the field of our contributions to sustainable living and energy efficiency.

Becker Travsmart Single Cable Lifeline Becker Mining South Africa has extended its range of Tractel personal protection equipment to now include the new Travsmart lifeline system, which is designed for safe and reliable use by up to five workers at one time. “Travsmart is a single cable lifeline which facilitates automatic travel through intermediate and turn anchors, with no need for manual intervention. A user can pass right or left of the lifeline, without the having to unhook the system when changing sides. This is a key feature for enhanced safety during installations, cleaning or maintenance,” says Charlotte Megannon, product manager for Becker Mining South Africa. “The flexibility of this system means it can be easily installed in all configurations, with inclinations of up to 15°. Travsmart can be mounted on traditional and low strength structures, including under ceilings, on walls, under an inclined surface, on the ground or on a post. “This lifeline cable system, which is quick to set up without the need for heavy assembly tools, eliminates the risks of an incorrectly crimped cable end. Intermediate supports can be easily changed if necessary and in the event of a fall, components are replaced, without having to disassemble the entire the lifeline.”

Becker Mining South Africa has extended its range of Tractel personal protection equipment to now include the new Travsmart lifeline system, which is designed for safe and reliable use by up to five workers at one time.

Travsmart consists of a slider, which is an opening-type anchor point that slides on the lifeline cable and can be positioned and removed anywhere along the lifeline. For user convenience, this device can be opened with one hand only. This positive-locking safety slider prevents an unintentional release from the lifeline. Self-blocking end pieces ensure the lifeline cable is always under tension (100 kg). Other components include galvanised or stainless steel cable (5 strands x 19 wires, or 7 strands x 19 wires) with a cable thimble, INRS shock absorbers, as well as intermediate and angle supports. Becker Mining South Africa’s range of Tractel equipment, which includes lifting and pulling equipment, as well as personal protection systems, meets stringent international safety and quality specifications. The company offers a test, repair and maintenance service to ensure all equipment operates in perfect condition.




Scaw Metals welcomes proposed curb in local scrap industry Scaw Metals Group, a leading manufacturer of steel products in South Africa, welcomes the proposed curb on scrap exports by the South African government.


conomic Development Minister, Ebrahim Patel published a draft policy directive in the Government Gazette earlier this year, which proposed measures to further curtail the export of scrap metal and ensure a steady supply at a price that supports local industry and the state’s infrastructure plans.

Mr Khumalo said that the South African scrap market was saturated by exporters. “Hence local producers have to purchase scrap at a high price to keep it in the country. This legislation will allow less scrap to leave the country and more of it to stay in the country.

Scaw’s scrap metal processing plant in Union Junction, Germiston in Gauteng, has the largest scrap shredder in Africa. Its Executive Chairman, Ufikile Khumalo, believes that the proposed plan will not only benefit his company but the entire local industry. The proposed scrap export legislation should make better quality scrap available to local consumers, thereby reducing preparation costs and waste losses, which will, in turn, improve efficiencies.

He added that it is likely that if the legislation is implemented local producers would be able to get their hands on raw material at a lower price.

“The ability to keep the best quality of scrap in the country will only benefit the industry and players like us. As steel is one of the few truly 100% recyclable metals in the world, we are able to reuse and reproduce the same material of the same quality again and again,” he said.


“South Africa doesn’t need to import finished steel into the country from India and China,” he said. The lower the price of scrap and the final steel products, the more local refineries and organisations can buy and sell additional steel products. This will increase productivity levels in the local industry. “By improving productivity the number of local buyers and sellers will increase, hence boosting job creation in the country,” said Mr Khumalo.

CHIETA hails new ‘significant’ partnership with coatings sector The Chemical Industry Education and Training Authority (CHIETA) has hailed its partnership with the SA Paint Manufacturing Association (SAPMA) to develop skills in the coatings sector as a “significant contribution to the industry.”


n a press statement, Ayesha Itzkin, Acting CEO of the CHIETA, says, “CHIETA is confident that this partnership will prove successful and make a significant contribution to the industry as it is one of the key principles underpinning the National Industrial Policy (NIP) framework, and the five successive iterations of the Industrial Policy Action Plan.” In terms of the partnership, SAPMA with the CHIETA recently opened the Coatings Centre of Excellence in Springs and began registering students for the various courses on offer. The Centre is targeting to train approximately 200 students in technical training and handle a further 100 paint application learnerships during 2013. The Centre’s first intake of paint applicators took place on July 1 this year in Springs and the students are currently undergoing training incorporating practical paint application in the course, NQF level 2 – 6 Technical Training and Business Training for the Retail Sector, which is also open to non-technical students. Training at the Centre of Excellence will be expanded in 2014 to include waterproofing, spraypainting, corrosion and powder coatings. SAPMA’s training arm, the SA Paint Industry Training Institute (SAPITI), has over 25 years’ experience in providing essential technical skills training for the surface coatings industry. Its training courses include 11 distance learning modules based on the British Coatings Federation distance learning modules in terms of content methodology and assessment. BCF qualifications are recognised internationally. These training modules, now accredited by the CHIETA, have been used by over 7 000 students since the introduction of the modules over two decades ago. For example, in 2002 the Nelson Mandela Metropolitan University in Port Elizabeth also introduced a paint technology course which uses five of these modules in its qualification towards the National Diploma Polymer Technology (Surface Coatings). “The coatings industry passionately supports the training of our workforce and the new Centre of Excellence is a superb example of the relationship development and cooperation between the Government and the private sector,” comments Deryck Spence, Executive Director of SAPMA.


Mahlatse Xinzi, Regional Skills Advisor: Gauteng Central Region of the CHIETA, spelt out how members of the coatings industry could access government financial incentives by submitting Work Skills Development Programmes at the recent SAPMA annual general meeting.The CHIETA has hailed its new skills development partnership with SAPMA as a ‘significant contribution’ to the welfare of the industry.
