EDITOR’S commentS
From solar to steel Welcome to the May issue of the SA Roofing magazine.This month, we take a look at the state of grid connect rooftop solar photovoltaics in South Africa, the new Green Building Council SA’s (GBCSA) rating tool for public and education buildings, light steel frame building, and the TotallyConcrete Expo taking place from the 3rd to the 5th of June.
O
n page 24, Stephen Forder, SESSA online editor, offers insight into the state of solar PV in South Africa. Although “grid connected systems are now near to grid parity, where the cost of electricity produced from privately owned rooftop PV modules is equal to, or less than, the cost that the consumer would be paying for electricity from the grid,” an established framework seems to be lacking. The new Green Star SA – Public & Education Building rating tool, as with existing Green Star SA rating tools, is one with which to gauge “the environmental attribute of new or significantly refurbished building developments. The tool assigns a Green Star SA rating to the building as a whole on the basis of its design and rewarding sustainable building design attributes.” Read more about this on page 8. We also offer an update on the recent SteelFuture conference, which “has been hailed globally as an unmitigated success,” and a project feature on the beautiful Waterfall Country Estate home that has been built using the light steel frame method.

Significant endorsement for Light Steel Frame Building at SteelFuture Conference At the recent SteelFuture conference - which has been hailed globally as an unmitigated success - the future of the global steel construction industry was discussed by experts from all around the world. It was unanimous that the sustainability properties of steel, and light steel frame building (LSFB) in particular, are a key factor in the pivotal role that steel will play in the future of construction.
A typical light steel frame structure.
T
he SteelFuture conference was hosted by the Southern African Institute of Steel Construction (SAISC) at the Sandton Conference Centre in March 2013, with Cadex SA as the main sponsor and other supporting sponsors including MiTek, Aveng Trident Steel, Arcelor Mittal, Peddinghaus, Macsteel and Vital Engineering. Maribeth Rizzuto, Director of Education and Sustainable Construction, Steel Framing Alliance, and Managing Director, Cold-Formed Steel Engineers Institute of the USA, a speaker at the conference, said that, going forward, the steel construction industry must respond to the increased focus on safety and sustainability issues while maximizing the return on investment for the owner.

“This has been brought about in the US and other countries primarily due to the increased level of natural disasters that we have seen recently. While LSFB is positioned very well because of its inherent characteristics of consistent high quality, noncombustibility, recycled content and recyclability, we must continue to develop technologies that can deliver LSF assemblies that hasten construction and reduce cost,� Rizzuto said. Rizzutto said that, armed with numerous strategic alliances and the publication of many design and construction standards and guides, LSFB continues to be well-positioned for healthy growth in the US and in South Africa.

Light Steel Frame method is becoming increasingly popular in multi-storey buildings. This is on site at a new head office in Woodmead, Johannesburg for a well-known company. “The building community has become more aware of LSFB’s capabilities, which has led to new and challenging uses for the material once limited to partition and curtain walls. Today, load-bearing applications for LSFB are being used for exciting projects in the hospitality, retail, assisted living, multifamily and mid-rise markets." “It is hardly surprising that in a down economy, developers are implementing strategies to maximize their return on investment while producing award winning projects. In some cases, in densely populated urban areas especially, the only way to go is up - and that is just where the developers of multipurpose, mixed-use projects have gone to fulfill their goals,” Rizzuto said. One such example, said Rizzuto, was in the urban setting of downtown Pittsburgh. Once described as “hell with the lid lifted,” Pittsburgh continues to undergo a rebirth of its central core with visionary projects like Piatt Place, the site of a former four-story department store with three stories of underground parking, which has been converted into what some have referred to as an urban oasis. Owned by Millcraft Industries Inc., this project has been a major force in Pittsburgh’s revitalization that has contributed to putting downtown Pittsburgh on the map as the location for urban living.

This new seven-story mixed-use structure combines 50,000 square feet of retail space, 180,000 square feet of office space and 65 high-end condominiums. “And as valiant strides are being made to focus more attention on sustainability efforts through the reuse of existing building infrastructure, developers have also become extremely creative,” Rizzuto says.
Best choice framing Rizzutto explains that with attributes of high strength-toweight ratio, LSFB was the natural choice for the project. Long-term durability and flexibility in design afforded the owners the opportunity to produce these high-end condominiums at prices acceptable to the market, providing the project managers with a first-class addition to urban life in Pittsburgh. According to Chad Wheatley, Director of Construction for Millcraft, “The time it took to install the three-story structure atop the new steel platform was four-and-a-half months. Cycle-time savings were realized in the exterior envelope, which was also, by and large, completed during the same timeframe as the LSFB framing system was panelized off-site.

Li g ht ste e l f r am e bu i ld i n g
Work around the roof With respect to the residential portion of the project, Rizzutto showed how it incorporated a heavy structural steel frame with a composite metal deck to create a platform over the existing roof. “This platform was necessary to support three stories of residential condominiums built around a beautiful central courtyard on top of the existing building. The additional residential storeys were constructed atop the concrete slab using LSF steel and a lightweight gypsum-concrete topping. “The use of LSF allowed the contractors to minimize the additional weight on the foundation and footing, so the existing structural framing could be used and upgraded to meet building code requirements for the extra loads with minimal additional costs, making the project economically feasible,” Rizzuto said. John Barnard, Southern African Light Steel Frame Building Association (SASFA) director said he was pleased, but not surprised that the LSFB method received such positive attention at the SteelFuture conference. “The advantages of the building method with respect to the demands of future construction challenges are clear,” Barnard said. “Construction is significantly faster with LSFB, because the lightweight steel frame is manufactured to spec in the factory and then assembled and erected very quickly on site.” “Once it is in place, the building can be enclosed and internal finishes, such as tiling and painting, can start much sooner than in a brick and mortar structure. The method also saves time, because it allows different disciplines to work concurrently, as Maribeth Rizzuto alluded to in her Pitttsburgh project description.” “Also, LSFB is significantly more energy efficient than more traditional construction methods – both with regard to ‘embodied energy’ of the materials and components, as well as ‘operational energy’ relating to heating and cooling of the building over its design life,” said Barnard.
SteelFuture and sustainability SAISC engineer, Amanuel Gebremeskel, says that the one concept that is ubiquitous at nearly every forum on the future (and this was certainly the case at Steel Future 2013) is sustainability. He adds that President of the Arizona-based Bjorhovde Group, Reidar Bjorhovde, in his talk at the SteelFuture conference described sustainability as “a broad concept that circumscribes how we should utilize our social, economic and natural resources in such a way that we can ‘satisfy our own needs without compromising the ability of future generations to meet theirs.’”
Maribeth Rizzuto, Director of Education and Sustainable Construction, Steel Framing Alliance, and Managing Director, ColdFormed Steel Engineers Institute of the USA.
Moreover, we must be able to pass these materials and technologies on to future generations without degrading their usefulness. Finally, sustainability requires that our immediate social well-being, and our use of materials and technology, do not compromise the most important public asset that we have – the natural environment. Barnard says that, given Bjorhovde’s definition of sustainability, there is little doubt that the LSFB method will grow strongly in popularity in this country. “It has all the attributes to become a mainstream building method in the near future and beyond,” he concluded.
Bjorhovde went on to explain that first and foremost, sustainability is about keeping us and our children safe from immediate dangers that arise from natural or human-made anomalies. These can range from earthquakes to arson, and can cause tremendous damage to society. Sustainability is also about choosing materials that are economically accessible and flexible to work with.

Rating tool for Public and Education buildings extensively tested The latest green building rating tool launched by the Green Building Council of South Africa (GBCSA), the Green Star SA - Public & Education Building (version 1) Rating Tool, was first put through its paces in an extensive pilot project carried out on a number of public buildings in South Africa and is now freely available in digital format.
Greening public spaces
From a Museum to a University
Funded by the Construction Industry Development Board (cidb), an agency of the National Department of Public works (DPW), this latest tool enables the GBCSA to rate public spaces, such as community centres, libraries, museums, places of worship, indoor sports centres, entertainment, exhibition and convention centres and public transport terminal buildings, regardless of whether these buildings are publicly or privately owned. The rating tool extends to Education buildings, such as schools and tertiary education facilities.
Prior to the launch of this latest tool, the GBCSA put the pilot version of the Public & Education Building rating tool through its paces on a few projects across the country in order to improve and streamline it for the South African market. These projects emanate from both the public and private sector. One such pilot project was the Grahamstown National English Literary Museum (NELM).
As with the other Green Star SA rating tools, the Green Star SA – Public & Education Building rating tool assesses the environmental attributes of new or significantly refurbished building developments. The tool assigns a Green Star SA rating to the building as a whole on the basis of its design and rewarding sustainable building design attributes. “What’s exciting about the Public & Education Building rating tool in particular, is that we are now seeing a move into a much broader range of buildings, where government will play a significant role,” says Brian Wilkinson, CEO of the GBCSA.

Marloes Reinink, sustainable building consultant from Solid Green Consulting, who handled the testing of the Public & Education Building rating tool pilot for this building explains that the first step undertaken was a workshop with the entire team to define the Green Star SA strategy for this project and to assist with the prepation of the relevant documentation. “Because this project was only in its pilot form, there were a number of queries and a lot of communication with the GBCSA - which significantly helped the Technical Consultants that were developing the tool to implement improvements,” says Reinink. “The initial goal was a 4-star Green Star SA rating, However, after the workshop it appeared that the project would be able to target a 5-star Green Star SA rating.”

Some green initiatives at the Grahamstown National English Literary Museum (NELM): • Large ‘green’ roof over the Archives, assisting constant temperature control • Rainwater collected and reused for toilet flushing • Xeriscape garden with endemic landscaping design • Building is not fenced off and outside areas open to the public throughout the day • Education is a focus point, live metering display and educational posters in the entrance of the building Another building that took part in the pilot period was the Nelson Mandela Metropolitan University (NMMU) Business School. Andy Kopelowitz, an engineer from Arup, handled the pilot project for NMMU and explains that going through a pilot process is not vastly different to pursuing a Green Star SA rating under a finalised tool. “There is the constant management of the Green Star SA process during the design stages, and specialist input into specifications and design items to ensure that the intention of the project to meet the Green Star SA requirements is achieved.” “The Green Star SA Accredited Professional (AP) was in regular contact with the GBCSA, raising various queries, most often relating to how compliance with a credit is measured and how certain aspects of the ‘fine print’ in the Technical Manual related to our particular building type.”
Putting the tool through its paces
“The project was required to submit formal comments on the tool to the GBCSA for consideration, and these comments, plus the numerous queries which were submitted as they arose, assist the Council in ensuring that the final version 1 of the tool is succinct and robust.”
Some green initiatives at the Nelson Mandela Metropolitan University (NMMU) Business School: • Rain water is harvested and used for 100% of toilet and urinal flushing, and allowance for irrigation. • Major materials are being sourced locally (concrete and masonry). • A minimum of 70% of waste generated during construction is being sent for recycling or being re-used. • Bicycle facilities are being provided for staff and students. • Topsoil is being preserved for re-introduction on site once construction is completed. • Low-VOC paints, carpets and adhesives have been specified to reduce indoor pollutants.
Green Star tools instrumental in the take-up of green building practices “The ongoing strategic expansion of available rating tools by the GBCSA is being driven by the demand for increased coverage of the property sector and the acknowledgement of unique environmental issues attributed to specific building types,” says Manfred Braune, Technical Executive - GBCSA.
“The purpose of a pilot project is to test the tool and target pilot certification, and this means that we were required to raise any issues with the GBCSA,” says Kopelowitz.

G BCSA The Public & Education Building (version 1) rating tool Technical Manual is available for the first time in digital format and as a free download to GBCSA members and students. Non-members can anticipate paying R700 for the manual. The rating tool and related documents are freely available on the GBCSA website. “Green Star SA establishes a common language for the industry and importantly, recognises and rewards excellence in environmental leadership.
Rating tools have been instrumental in marking the mainstream take-up of green building practices in a number of markets worldwide, and South Africa is following this trend,� concludes Wilkinson. Visit www.gbcsa.org.za for more information on Green Star SA rating tools.

Magnificent Waterfall Country Estate home built with light steel frame method
If there were any doubts that the light steel frame building (LSFB) method is appropriate for upmarket housing in South Africa, then the magnificent new Kevin Els-designed home, built by Ivecon Projects in the new Waterfall Country Estate development north of Johannesburg, will certainly help to finally put those doubts to rest.
T
he spacious double-storey, which has 680m2 under roof and a host of impressive design features – including breathtaking cantilevers, a home theatre, and a glasswalled wine cellar within the hypermodern kitchen – is a testament to the possibilities offered by LSFB. The initial idea to use LSFB came from Els, of the innovative Fourways-based Els & Associates Architectural Studio. “This is a new methodology that has really stuck its head out in South Africa, and when I became aware in early discussions that time was of the essence, I insisted that we investigate LSFB as an option,” he says. Construction is significantly faster with LSFB because the lightweight steel frame is manufactured to spec in the factory and then assembled and erected very quickly on site. Once it is in place, the building can be enclosed and internal finishes, such as tiling and painting, can start much sooner than in a brick and mortar structure. The method also saves time because it allows different disciplines to work concurrently. It is not necessary, for example, to wait for a completed façade before finalising accurate measurements for windows.
14
LSFB can also be used in conjunction with heavy structural steel, which may be required for long spans or cantilevers, or to expose as part of the architectural expression. But time-saving efficiency is only one of the many advantages of the LSFB method – others include environmental sustainability and long-term cost-saving. John Barnard, director of the Southern African Light Steel Frame Building Association (SASFA), explains that LSFB is significantly more energy efficient than more traditional construction methods – both with regard to ‘embodied energy’ of the materials and components, as well as ‘operational energy’ relating to heating and cooling of the building over its design life. 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 an equivalent masonry residential building to comfortable internal temperatures. This means significant cost-saving on heating and air-conditioning in the long term.

Li g ht ste e l f r am e bu i ld i n g
Steel is also a reusable and recyclable material, which means that it reduces the overall carbon footprint of the project and assists in compliance with the SANS 10400-XA:2011 national building regulations. Sven Iversen, founder and director of Ivecon Projects, the construction and project management team involved with the project, has travelled extensively worldwide and says that in Europe, New Zealand and Australia, LSFB is the growing trend.
South African building market catches on to the advantages of the LSFB method.” Iversen says the building industry is continually evolving and that technology is the driving force. “Traditional building methods are no longer the only answer. Ivecon Projects embraces new technologies and is moving toward innovative, energy-efficient methods of construction, fast-tracking construction time which translates into cost savings for our clients,” he says.
“In South Africa, people are simply used to brick and mortar building, but it is only a matter of time before the mainstream

Li g ht ste e l f r am e bu i ld i n g Ivecon Projects recently won the Best Built Home and the Green Design award at the prestigious Century Properties home show.
Because no expansion joints need to be cut, a smooth, waterproof exterior surface is achieved.
From a construction point of view, there are numerous advantages to LSFB. Steel is unequalled in meeting tight construction schedules in any weather conditions, a smaller construction team is required, and because a limited amount of masonry work, if any, is required on site, LSFB ensures a cleaner and safer construction site.
Barnard said that as the market increasingly realises that LSFB can be used for a range of different applications and takes into account the considerable benefits, both practical and financial, of the building method, perceptions about traditional building methods being the only viable alternatives are being questioned. “There are more and more local examples of striking buildings that are being built with LSFB,” he said.
“From an architectural perspective,” says Els, “there are many reasons for the architect to feel comfortable and confident when designing with light steel framing. It is flexible enough to handle complex design elements, giving you freedom of expression in your design methodology. Also, steel has slenderness and grace when required to span distances and cantilevers.”
Barnard added that projects such as this are helping to break the myth that quality structures have to be built using heavy masonry or reinforced concrete. “Prejudices in South Africa against non-traditional building methods such as LSFB are on the wane and the more people see such quality structures being built, and realise the environmental benefits, the more they are opening up to these new methods of construction.”
Els added that allowance must also be made in the design to cater for technical issues such as truss depth – as opposed to concrete slab thickness – as well as bracing methods, external or internal treatments and finishes and cladding, for example.
SASFA, formed in 2006, is a division of the Southern African Institute of Steel Construction (SAISC).
“Although the majority of the bracing elements are handled by the steel frame supplier and engineer, a close relationship between the architect and steel engineer/steel frame supplier should be maintained to enable a range of elements in the design such as ducting, electrical points, plumbing recesses, fixtures and finishes to be incorporated successfully,” he said.

The silky deep-grey exterior of the house was achieved using 60mm thick EPS (expanded polystyrene) lightweight cladding, fixed to a light steel framework. The expanded polystyrene is plastered with a special, colour-impregnated polymer plaster rendering.

Grid connected rooftop solar photovoltaics near grid parity, but an established framework is lacking Words: Stephen Forder, SESSA Online Editor
S
outh Africa has one of the best solar resources in the world, and with photovoltaic modules being the cheapest they have ever been (the landed price has dropped more than 50% in the last 2-3 years), grid connected systems are now near to grid parity, where the cost of electricity produced from privately-owned rooftop PV modules is equal to, or less than, the cost that the consumer would be paying for electricity from the grid. Add to this concerns about security of supply and possible loadshedding caused by Eskom's planned winter maintenance schedule and probable delays in bringing more capacity online from South Africa's new coal-fired behemoth, Medupi, which is beset with labour and construction issues, it is difficult to see why South Africa hasnâ&#x20AC;&#x2122;t grasped the rooftop opportunity a lot earlier.
24
Germany has a far lesser solar resource, yet ordinary citizens now own a significant proportion of the countryâ&#x20AC;&#x2122;s renewable energy generation capacity. Rooftop PV technology is mature and easy to deploy, far easier than building new coal-fired or nuclear power plants, and presents real opportunity for South Africaâ&#x20AC;&#x2122;s energy and socioeconomic aspirations, which are tightly coupled, due to the opportunities for green job growth that a robust distributed, embedded electricity generation programme would foster, particularly in the SME and SMME sectors.
M AY 2 0 1 3
Ph otovo ltai c s
Yet onerous legal requirements in some instances, massive amounts of red tape and the lack of over-arching policy is holding the rooftop agenda back. And if that isn't enough, there is also a financial disincentive for local authorities to facilitate embedded generation with many of them deriving a disproportionate amount of their revenue from electricity sales, which serves to cross-subsidise other essential services. These are all obstacles which urgently need to be overcome.
Despite these obstacles, and a lack of an established framework, however, private entities and individuals are starting to install rooftop PV and are connecting systems to the grid. This practice not only improves their green credentials, but reduces energy costs and enhances the security of their electricity supply. Whilst cost has always been a major obstacle to the adoption of rooftop electricity generation at the smaller scale, the payback time for a grid connected system at the current rate per kWh can now be 5 to 7 years under a suitable consumption profile and tariff conditions and if you can afford the upfront investment, youâ&#x20AC;&#x2122;ll be generating electricity for free after that, probably for a lot longer than the guaranteed 20-25 year life-span of the system. Encouragingly, the major financial institutions are also starting to look at innovative finance schemes in order to get over the initial upfront cost hurdle of installing the necessary equipment. At the larger end of the rooftop scale and more appropriate for commercial installations, Eskom launched a rebate scheme for smaller renewable energy technologies in late 2012, which includes solar PV, with eligible installation sizes ranging from 10kW to a maximum of 1MW generated over the 16-hour daily window (06h00 â&#x20AC;&#x201C; 22h00). The smaller size equates to a solar array peak capacity of around 30kW. It is hoped that, in due course, smaller system sizes will also be included which would allow home owners to avail of the rebate (currently, the systems targeted for the rebate are beyond the needs of your average residential consumer). The rebate is pegged at R1.20 per kWh over a 3-year period, with a disbursement as per SOP rules of 70% on commissioning and 10% at end of years 1, 2 and 3. A Measurement and Verification procedure applies which includes a 2-3 month baseline study to determine the projected energy savings over the 3 years and this is used to calculate the overall rebate amount.

The Sustainable Energy Society of Southern Africa (SESSA) is dedicated to the use of renewable energy and energy efficiency including all solar-based energies, such as solar PV, thermal heating and cooling, wind, biomass and hydro power. It was founded in 1974 and is one of 50 National Sections of the International Solar Energy Society (ISES). The largest, oldest and most comprehensive technical body dealing with the technology and implementation of renewable energy, ISES was founded in 1954 and has representation in more than 100 countries. The inter-disciplinary nature of SESSA attracts the membership of industry, scientists, researchers, developers and the general public and the Society has shown good growth in its solar photovoltaic division in recent years. As other industry bodies are established to represent larger, utility scale technologies, such as large-scale wind farms and solar power stations, SESSA focusses on smaller scale rooftop technologies and has been a key partner, along with Eskom, in the implementation of South Africa's solar water heating programme to date. This stands the organisation in good stead to promote and support the rooftop PV generation agenda from the ground up. SESSA PV division members have been involved in numerous turnkey installations in the commercial, industrial and residential realms.
Grid-connected systems Currently, a grid connected PV system presents the only economically viable opportunity for home owners and other private entities to generate their own electricity. These systems have no storage other than the grid itself. Any excess electricity is fed back into the grid. At night, or during times of intense cloud cover, the building draws on power from the grid. In a net-metering scenario where there is no feed-in tariff, it is wise to size the system to provide less than the buildingâ&#x20AC;&#x2122;s load, as you will not be paid for any excess that you may feed back into the grid.
25
Ph otovo ltai c s
To optimise one’s own consumption rather than generating unpaid feed-back into the grid you should try and synchronize consumption with solar production as much as possible, i.e. shift electricity use as much as possible towards sun-time. Electrical load considerations, other than those which exceed your grid supply capacity, are not important. A 1 kWp grid connected system will cost in the region of R25 000*.
Battery use needs to be monitored and managed carefully, and care should be taken not fully to discharge or overcharge batteries, as this shortens their lifespan and impinges negatively on the system’s efficiency.
Hybrid systems
*These costs are only a rough guide and are always subject to a site visit and proper designs being done for each location.
These systems are grid-connected, but also have some storage capacity. They provide some measure of continuity when the grid goes down at the same time, as there is not sufficient solar input. For example, one may choose to run critical appliances, such as a computer and an internet router during a loadshedding episode, while switching off all other electrical appliances. Batteries are charged by the grid when there isn’t sufficient solar input. The cost depends largely on how much battery storage is incorporated into the system.
Storage is the most expensive component of PV systems. A 1 kWp grid connected system will cost in the region of R60 000*.
Please visit http://sessa.org.za/sessa-membership/member-database to locate a supplier.
Off-grid systems These systems are suited to remote locations where a grid connection is not available. The battery bank is sized to provide a certain number of days of storage and the building draws on this store during the night or during days of intense cloud cover.

Mapei introduces in situ waterproofing system Mapei South Africaâ&#x20AC;&#x2122;s latest product offering to the local market is the Purtop in situ membrane waterproofing system. For the past five years, the Mapei technical service team has been introducing the local construction industry to the benefits of the advanced building technology additives, sealants, adhesives and concrete performance chemicals that are available from the international Mapei Group. Offering market-leading performance and handling advantages, Mapeiâ&#x20AC;&#x2122;s 1400 products are recognised throughout Europe, America and the Far East.
Purtop being applied to prepared surface.
T
wo grades of Purtop are being offered: Purtop 400M and Purtop 1000. The 400M grade is a two-component solvent-free product that is applied by spraying with a high pressure, bi-mixer type pump to form a hybrid polyurethane membrane. The membrane is suitable for applications such as the immediate on-site waterproofing of decks on bridges and viaducts. It has extremely good resistance to alkalis, dilute acids and detergents, combined with excellent tensile (14 N/mm2 in terms of DIN 53504) and tear strength (55 N/mm2 according to ISO 34-1), while its rapid set allows light foot traffic within 20 minutes. Purtop 1000 is a two-component, solvent-free product that is spray-applied to form a pure polyurea membrane. Suitable for continuous exposure to water, the membrane is used to waterproof storage tanks, basins and water works in general. The product also has extremely good resistance to alkalis, dilute acids and detergents, combined with exceptional tensile strength (25 N/mm2 in terms of DIN 53504) and tear strength (96 N/mm2 according to ISO 34-1). Due to its quick set, light foot traffic is possible within 10 minutes. Both Purtop products may be used on new and old structures to form a continuous waterproof coating with an excellent bond to a wide variety of materials. The membrane adapts to any shape of substrate without cracking.
28
Ideally, the membranes should be formed on a surface that has been well-prepared by sanding or shot-blasting. In keeping with Mapeiâ&#x20AC;&#x2122;s total solution approach, a range of primers for different substrates is available, as well as preparation systems for less than ideal surfaces. These include cavity repair grouts and epoxy primers to speed up work when residual moisture levels in the substrate are higher than recommended, and rust prevention epoxy primers for steel. Mapei South Africa is confident that Purtop 400M and Purtop 1000 will add to their track record for setting new performance benchmarks for speciality chemicals in the local construction industry.

a.b.e. supplies Dow Corning sealants for rebirth of Lusaka iconic skyscraper Dow Corning structural glazing sealants, distributed in South Africa by a.b.e. Construction Chemicals, were chosen by applicator, Preplan, as preferred products to be used on the facades of one of the most notable Zambian building projects in recent years: the refurbishment of Lusaka’s Society House.
An artist’s impression of what the refurbished Society House in Lusaka will look like after its current refurbishment programme.
S
amantha Ferreira, Product Brand Manager for Silicones, Sealants and Specialist Adhesives at a.b.e., says the firedamaged 20-storey Society House – for years an iconic highrise structure in the Zambian capital – is being reconstructed to feature a 4-star, 160-room Holiday Inn with conference facilities, a shopping mall, A-grade offices, and 1 100 car parking garage.
A South African consortium of architects Louis Karol, quantity surveyors Turner & Townsend, property agents Pam Golding Properties, and electro-mechanical engineers BWK Monamodi, together with a Zambian consortium are handling the R680 million refurbishment of the Lusaka landmark which was gutted by fire in the 1990s. Dow Corning’s Quality Bond Technical Distributor, a.b.e. Construction Chemicals, is supplying its Approved Quality Bond applicator, Preplan, with four Dow Corning products for the structurally glazed facades of Society House: • Dow Corning 993 structural sealants which Preplan is using at its factory for the glazing of the curtain wall panels; • Dow Corning 895 which is being used on-site when required for replacement glass;
30
• Dow Corning 813C, which Preplan is using in its factory for joint seals to extrusions and also on-site for capping fixing anchors, flashing and termination points on structure; and • Dow Corning 1200 OS UV Traceable Prime, which is being used in conjunction with the DC 993 and DC 895 on the frames prior to applying the silicone. DC 993 is a two-component, neutral curing silicone formulation specifically developed for the structural bonding of glass, metal and other building components. It has an exceptionally high level of mechanical properties and can be used in impact-resistant window systems. DC 993, available in black and white, allows for maximum energy efficiency in construction as it provides total vision glass without thermal bridges, and is resistant to ozone and UV radiation. DC 895 is a one-part, moisture-cured structural silicone formulation. DC 813C is a low modulus sealant particularly suitable for weather seals, expansion and perimeter joints in buildings (both internally and externally). It offers durable adhesion to porous and non-porous surfaces, such as concrete, masonry, brick, PVC-U, wood and glazed surfaces.
M AY 2 0 1 3
for safety and durability. Quality Bond applicators, furthermore, have to be audited annually to have their certification renewed,” Ferreira states.
Ferreira says the reputation of Dow Corning silicone sealants, already for many decades the top quality standard for structural glazing, has been further enhanced by the company’s Quality Bond proven applicator programme, which offers specifiers and developers added peace of mind.
Dow Corning also markets and promotes the services of Quality Bond members among specifiers worldwide and offers its respected technical expertise to ensure that projects are carried out according to the company’s strict quality control system. Laboratory testing on substrates to check adhesion, compatibility and staining enable Dow Corning to make formal recommendations for the product selection and use.
Dow Corning sealants have been supplied by a.b.e. for diverse structural glazing applications including towering skyscrapers, such as the Bank of Mauritius in Port Louis, 15 Alice Lane Towers in Sandton, ICC in Durban, Protea Place office tower in Sandton, and the Vodaworld staircase in Midrand. More recently, Dow Corning sealants have also been specified for Portside which – at 139m – will, on completion, be the tallest office block in the Cape Town CBD, and a new Allan Gray high-rise development on the Cape Town Foreshore. Preplan has also chosen Dow Corning products for the facades of the new high-rise headquarters for the Reserve Bank of Mozambique. “Apart from its proven track record, the growing popularity of the structural silicone sealants can also be linked to the Quality Bond Programme introduced by Dow Corning. With inadequate application, even the finest sealants can fail, but now specifiers and developers are assured that Dow Corning sealants applied by Quality Bond applicators meet the company’s most stringent rules of compliance.
“The provision of blueprint reviews, design calculations for structural and weathersealing joints, project audits, training and the ‘Level Three’ warranty all contribute to the total peace of mind package now offered to specifiers,” Ferreira adds. a.b.e. Construction Chemicals is the sole Southern African technical distributor for the Dow Corning range of structural glazing sealants, insulating glass units, instant glaze (hot melt silicone), and sealants for expansion joints on highways, airport aprons and bridges. The latter have, for example, been used on national highways and Gautrain viaducts. Dow Corning’s self-levelling silicone joint sealants can be used in conjunction with a.b.e.’s renowned flooring and concrete repair systems, and have successfully been applied on major airport runways. a.b.e. Construction Chemicals is part of the Chryso Southern Africa Group.

"The next step for transparent OLEDs is industrial series production, and we'll be tackling that in 2014," remarked Ulrich Eisele, responsible for the OLED sector at Osram. OLEDs have no visible conducting path and feature secure encapsulation, until now a major deficiency with the transparent light source.

OLEDs in this way unite the photometric benefits of both direct and indirect lighting. Panels and the luminaire itself were developed at the Osram location of Regensburg in Germany. Federal Ministry of Education and Research project called GENESIS is a scaling down to manufacture-compliant processes and substrate sizes. Glass substrates sourced from SaintGobain are used based on the new Silverduct technology, and these enable lower cost production compared to earlier processes.
Luminous semiconductors Technically speaking, OLEDs, as with LEDs, are semiconductors that convert electric current to light. While LEDs emit point light from a tiny luminous chip, OLED panels are luminous Brilliant and clear: OLEDs are expected to be the primary choice for transparent, surfaces produced by vaporizing various organic wide-area light sources in the future. plastics onto a substrate material. The luminous layer of an OLED is approximately 400 New is also the possibility of defining a specific light distribution nanometres thick, corresponding to one hundredth of a human side with the transparent OLEDs featuring distribution on both hair. OLEDs according to base material appear reflective, sides: in the one direction the light merely has a decorative neutral white or transparent in switched-off state function as it is weaker, but in the other it can be used functionally, for purposes of illumination.

well positioned to play a leading role in providing reliable and independent electricity to support the country’s growing economy and to combat the affects of rising utility costs.
M AY 2 0 1 3
ART Solar’s KZN manufacturing plant, with the latest equipment from Swiss manufacturer – Meyer Burger Swiss Solar Systems – is geared to produce about 250 000 PV modules or approximately 75 MW/year. These modules can be 48, 60 or 72 cell modules, with a glass-backsheet or with a glass-glass construction. Every module manufactured at ART Solar meets the exact specifications of each customer. These requirements include the percentage of local content necessary, as well as aesthetic needs. “With the investment in solar PV modules, users are able to generate electricity and benefit from cost savings in the long term. An advantage for the local market is that funding for renewable energy projects is available. South Africa will also benefit from noting the faults and successes of solar power projects implemented around the world,” says Mark Walsh, managing director, ART Solar. “PV technology is a reliable and proven source of electricity because of its environmentally friendly and cost efficient features.” “The sun is the only resource needed to power PV panels and the silicon used in the manufacture of PV cells is an abundant and non-toxic material. PV modules produce no noise, no harmful emissions and no polluting gases. These modules can be recycled, which means materials used during manufacture are re-used.” “Other important features include easy installation and low maintenance requirements. ART Solar offers a 25-year guarantee for its modules, which have an estimated 40 year service life. All modules are manufactured according to stringent quality, environmental and safety specifications.” The company’s commitment to meeting the exact requirements of the African market is evident in the development of PV modules specifically for local climate conditions. Special encapsulants are used to prevent delamination and yellowing in high insolation conditions and ensure extended service life of modules at elevated temperatures. PV panels are designed for large scale power plants, mines and rural electrification, as well as industrial and residential roofing. Modules with enhanced aesthetics are manufactured for residential and commercial installations. This environmentally-friendly system can also be integrated into roofs and facades to reduce the energy buildings consume. ART Solar provides extensive technical skills training for the production team and installers to ensure absolute reliability of every module and hence a sustainable local business, with local employees.

Mapei helps waterproof synagogue roof with durable Mapelastic Foundation Building contractors, M-Proofing Roofing & Waterproofing recently used a product from Mapei, the industry leader in the supply of building and construction materials and locally represented by Mapei South Africa, to waterproof almost 180m² of new roofing at the Mikvah at the Great Park Synagogue in Houghton, Johannesburg.
“Julian Michaels Architects required a non-bituminous roof covering, as rainwater from the roof is collected to be used in the ritual washing ceremonies in the Mikvah. We recommended Mapelastic Foundation, which waterproofs concrete surfaces that are subject to both positive and negative and higher and lower water pressures,” explains Paul Nieuwoudt, Product Manager for Building Systems, Mapei South Africa. Two-component Mapelastic Foundation is ideal for waterproofing manholes, concrete retaining walls, underground car parks, cellars, sunken swimming pools and sunken elevator wells where resistance against water pressure is needed. It forms an impermeable, cementitious, elastic membrane that is flexible, durable and moves with its substrate, maintaining advanced water resistance.
The project was completed within three days in May 2012.
About Mapei South Africa: Mapei South Africa is part of the Mapei Group, an Italianbased multinational that is a leading manufacturer of chemical and adhesive products for the construction industry. As part of the multinational group, Mapei South Africa passes numerous benefits onto its client base by having access to knowledgeable technical experts, research capabilities and product specialists. Mapei South Africa distributes its products throughout sub-Saharan Africa.
“It was the contractor’s first experience with our products and the performance, ease of use and outcome were so impressive that he has since specified Mapei products for three future projects,” says Nieuwoudt.

Full house for exhibitions at Coatings for Africa 2013 All exhibition space has been sold out for the Coatings for Africa symposium and exhibition to be held at Gallagher Estate from May 21 to 23 this year.
J
ointly presented by SAPMA and the Oil and Colour Chemists’ Association (OCCA), with the backing of the Department of Trade and Industries (DTI), Coatings for Africa 2013 will be the most influential and authoritative coatings event yet staged on the African continent, says Danny Grady, Chairman of the Local Organising Committee (LOC). The format of Coatings for Africa 2013 will be changed to accommodate a greater commercial element beyond its traditional technology transfer platform. It has also been decided to introduce a special reduced entrance fee for visitors who only wish to visit the 116 exhibition stands and not be part of the audience for the wide range of papers to be presented at the symposium. The entrance fee to visit the exhibition stands will be R100 per person per day on May 22 and 23. This year there will also be a special Business Presentation Arena where exhibitors and corporate companies will have the opportunity to showcase their services and products in a 15-minute presentation time slot followed by a five minute allowance for questions and answers. "CfA 2013 promises to be the most important calendar event ever for the African coatings industry. For many players the local market has been seen as saturated, so now, with the support of the DTI, it is a good time to step up their involvement in Africa", Grady adds. The DTI’s Ngwako Clement Manoko, Head of Communication and Marketing, has stated that his department viewed Coatings for Africa as "one of the initiatives where the stakeholders and role players in the industry can share ideas and showcase South Africa’s capacity in the sector.” Normally held every two years, Coatings for Africa was previously staged at a Drakensberg resort, but because of its growth and the need for a more accessible, centralised location, the venue this year will be Gallagher Estate in Midrand, Gauteng.

M7 air-operated tools ensure simplicity
for industrial and DIY projects
A range of internationally recognised Mighty Seven (M7) pneumatic air tools are available in the local market through Dowson and Dobson Industrial - a leading supplier of a comprehensive range of world class industrial products and after sales service solutions.
T
aiwan-based M7 has been recognised as a global leader in the manufacture and supply of pneumatic air tools for more than 20 years. Dowson and Dobson director Terry O'Kelly points out that the company stocks a wide range of M7 air-operated tools, including impact wrenches, ratchets, air die grinders, angle grinders, sanders, drills, screwdrivers and hammers. "M7 air tools are more cost effective than their electric counterparts, in addition to having a higher power-to-weight ratio. This is a result of the use of modern light weight material in the manufacturing process.The primary advantage of the M7 range of air tools is that they are not powered by electric motors, making them lighter and more manoeuvrable than electric tools. M7 air tools also reduce costs related to energy consumption, which is a major advantage in South Africa, where electricity prices have risen substantially in recent years," he explains. M7 air tools have proven to be popular in industrial projects for a number of years, and O'Kelly highlights the fact that they are gaining popularity in DIY applications too. "The portability and versatility of these tools has made them particularly popular in local manufacturing applications for five years. The range is now becoming more popular in DIY projects too, thanks to a small capital outlay that provides substantial overhead savings."
40
O'Kelly notes that the M7 brand is synonymous with quality. "M7 tools are reliable, efficient and tough enough to simplify even the most challenging jobs. What's more, all M7 products have international ISO and CE certification, thereby providing the user with complete peace-of-mind." As part of its exclusive partner support package, M7 supplies a complete set of maintenance manuals and training videos to authorised service partners such as Dowson and Dobson. O'Kelly adds: "In order to meet the immediate requirements of its clients, M7 offers e-learning through its website to give its marketing partners access to 24 hour on-line service and support." According to O'Kelly, the research and development at M7 is committed to technological advancement, in order to provide customers with more ergonomic, comfortable and efficient tools and equipment. "To meet international quality standards, M7 has invested a substantial amount of time and capital into developing a complete quality control process, ensuring that every product bearing the M7 brand meets or exceeds customer expectations in every way."

Looking to the future, O'Kelly is optimistic of the future outlook for Dowson and Dobson. "The South African economy is showing positive signs of recovery, which opens up the possibility of growth in both the industrial and DIY sectors of the economy. Having established a reputation as a tried and trusted brand in South Africa for five years, I believe that the M7 range of air tools will assist Dowson and Dobson in gaining market share in 2013 and beyond," he concludes.
About Dowson and Dobson Industrial Dowson and Dobson Industrial has been associated with high-quality products and excellent service since the original company was established in 1906. Operating throughout South Africa from offices in Johannesburg, Cape Town, Durban, Richards Bay and Port Elizabeth, the company today supplies industrial products to customers throughout Africa.

a.b.e. Construction Chemicals
opens new dustless powder plant As part of its sustainable development programme, the Chryso Southern Africa Group has built a new plant for the dustless manufacture of cementitious powdered products at the Boksburg premises of a.b.e. Construction Chemicals, which is part of the Group.
a.b.e. Construction Chemicals’ new Boksburg plant for the ‘green’ manufacture of dustless cementitious powdered products.
T
he new state-of-the-art powder plant, which started operating at the end of November last year, replaces a 30-year-old production facility that required modernisation and is, unlike its predecessor, almost fully automated.
“There is only a minimum degree of manual labour involved as certain compounds and pigments have to be added manually as they are not stored in silos. a.b.e. has also substantially reduced the need for staff to manually lift heavy bags of product, thereby reducing occupational health and safety hazards.”
Mario Marais, a.b.e. Construction Chemicals GM: Operations, says many of the products a.b.e. supplies to the construction and hardware retailing sectors were first produced more than 70 years ago. “Over the years, the need to produce the products with meticulous care to achieve top quality has remained unchanged, but globally there is today a far greater emphasis on respecting the environment and the safety of the company’s staff.
As a result of the increased automation and new equipment, the plant’s production capacity will now be double – or even higher than double – that of previous output levels, without the need for an increase in staff numbers.
“Dust levels are a major concern at powder plants so, as a safety precaution, extractor fans were installed in the new factory and all a.b.e. employees working in the plant now have to wear respiratory masks. As the dust levels were very high, additional safety measures were required and a new dust-free ribbon blade blender was installed and dust-free modifications made to the plant’s other ribbon blade blender and two plough blenders. To prevent the escape of dust, the plant’s conveyor belts had to be enclosed and the plough blenders, sealed. The new bagging unit is also enclosed.”
Marais says the investment in the new powder plant, coupled with the upgrading of the company’s Isipingo plant – where a.b.e. bitumen-based products are manufactured – form part of the Chryso Southern Africa Group’s continuing commitment to investing future growth and sustainable development.
Marais says as a further commitment to staff safety and producing dust-free products for customers, the plant’s plough blenders are fitted with atomisers that convert liquid to a fine vapour-like spray. To reduce manual input, the new plant’s nine silos are fitted with Programmable Logic Controllers (PLCs). The silos (of which three are brand new, and the others extensively refurbished) release the exact required amounts of raw materials on to the enclosed conveyor belts linked to the hoppers where the products are batched.
42
a.b.e.’s new powder plant is located behind the present factory in Boksburg and future plans include the conversion of the old powder plant to a liquid production facility.
“The plant is another example of the Group’s major emphasis on supplying dustless products. a.b.e. is now the only company in its sector supplying dustless mortars, grouts, plaster and self-levelling products in Africa. The ‘dustless’ concept has been devised and patented by the Parex Group, a subsidiary of the Chryso Southern Africa Group’s holding company, the Materis Group in France.” “We regard these exclusive rights to manufacture and distribute dustless products as a major advantage over competitors in the ‘green age’ the industrial sector is now experiencing,” Marais adds.

ABSA bank reports there was a 9.53% house price increase last year, which marks the greatest gain South Africa has seen since the onset of the global financial crisis in 2008. With the economy on the cusp of significant growth, the time is right to build relationships that will enable stakeholders to perfect their project delivery. The comprehensive TotallyConcrete programme includes a seminar wholly dedicated to finance and investment for real estate construction, housing, and socioeconomic development featuring future-proofed solutions for sustainable, commercially viable housing. Dan Brown, International Property Executive from Century Property Developments, will address the growth in the housing market during this seminar. The industrial, commercial and residential projects now cropping up across the continent are setting the pace and raising the bar for the African construction industry. A unique skill set and a crystal-clear picture of where the industry is headed is required to surmount the challenges that come with industry growth and change, and the TotallyConcrete Expo is set to provide a quintessential platform to launch the African built environment of tomorrow.

a.b.e. starts local production of
acclaimed underground waterproofing system a.b.e. Construction Chemicals has started the local manufacture of duraproof krystalkote, an internationally renowned cementitious waterproofing system, which protects and waterproof concrete structures through a process of crystallisation.
a.be. Construction Chemicals has started the local production of duraproof krystalkote, a waterproofing ideally suited for underground concrete structures such as parking basements. a.b.e. is part of the Chryso Southern Africa Group and has for decades produced acclaimed waterproofing products for the local commercial, industrial and residential markets. Lance Anderson, a.b.e. Brand Manager: Waterproofing, says environmentally-friendly duraproof krystalkote will now be produced at the company’s factory in Boksburg following a ‘black box’ agreement with Green Label Singapore. “In terms of the new agreement, the active ingredients of the waterproofing system will be shipped to us from Singapore, and a.b.e. will then add the non-active ingredients here at our plant.” duraproof krystalkote formed part of a wide range of ecowaterproofing products launched by a.b.e. two years ago. The product was then known as matryx k11 and imported as a completed product from Singapore. “duraproof krystalkote is the ideal waterproofing system for underground concrete structures, such as parking basements and other areas with negative hydrostatic pressure. The product’s active chemicals react with moisture in the concrete to form crystals in the pores and capillary tracts of the
46
concrete, thereby waterproofing the structure against water and other liquid penetration from any direction.” “It is suitable for any interior or exterior below grade surfaces to protect against concrete decay and waterborne corrosive salts. duraproof krystalkote can be used for negative waterproofing of concrete structures as well as horizontal structural slabs, and also provides strong resistance to impact and abrasion,” Anderson adds. He says the product can be applied dry shake form to waterproof concrete slabs during the curing stage, or concrete can be poured on a layer of duraproof krystalkote powder to add waterproof barriers to the concrete by virtually becoming part of the concrete mix. Areas of application of the product include basements, wet areas, tunnels, underground garages, planter boxes, and protection against rising damp on ground slabs. “It is available as a single component and is easy to apply,” Anderson states.

Advanced MSA EVOTECH harness improves worker comfort and safety Industrial operations can ensure the safety of employees working at height, by making use of advanced fall protection solutions, such as the EVOTECH industrial harness, which is available in the local market through the African division of MSA.
M
SA is a global leader in the development, manufacture and supply of sophisticated products that protect people's health and safety, and MSA Africa product manager for fall protection, Emmanuel Manaka points out that the company's EVOTECH full body industrial harness offers the latest design features that improve comfort, ease of use, durability and user safety. "Comfort is an essential aspect for workers that are suspended at height for prolonged periods, and the MSA EVOTECH harness comes standard with breathable padding complete with moisture wicking material to keep the user cooler, especially in the harsh African climate," he explains. Manaka highlights the fact that the MSA EVOTECH harness also boasts a sub-pelvic strap with patented variable width webbing, which provides 50 percent more surface area for improved weight distribution and comfort. "What's more, the elimination of a binding edge on the shoulder padding prevents neck chafing, while a patent-pending leg strap design keeps leg straps in place for increased mobility and comfort, and leg strap padding offers additional comfort during work positioning." Another distinct advantage of the MSA EVOTECH harness is its ease of use. Manaka adds, "Colour contrasting thigh and torso straps allow for simplified donning, while single hand torso buckles simplify harness adjustment. A built-in RFID chip ensures that the harness can be easily tracked and inspected at any time, while a three-position back D-ring allows for easy lanyard connection." According to Manaka, the MSA EVOTECH harness is highly durable, due to the fact that it is abrasion resistant, and repellent to hazards such as dirt, grease and moisture. "An added benefit is web finials that prevent fraying on web ends, and a covered label pack that protects labels from environment." With focus on added safety, Manaka notes that the MSA EVOTECH harness also has reflective webbing integrated into harness webbing, in order to increase visibility in low light environments. "The MSA EVOTECH harness is available in three different sizes to fit a wide range of body types and sizes, and comes standard in four different harness versions to ensure that the correct protection is being provided for a specific job," he concludes. The MSA EVOTECH harness meets EN 361:2002, EN 358:1999 and EN 1497:2007 quality approvals, and is ideally suited to numerous industries, including; oil and gas, mining, petrochemical and construction.
