this issue.
In this issue, we turn the spotlight, once again, on the hot topic of steel roofing, with an industry association overview, a comprehensive look at the design of world leading sports
stadia, and a great cover story.
The Southern African Metal Cladding & Roofing Association (SAMCRA) is featured on page 8, where the association’s composition and mandate are covered. The SAMCRA is motivated to “create an infrastructure on which an orderly industry can be built,” to “facilitate the fusion of the ambitions of the metal cladding and roofing industries with the requirements of the specifiers and clients to create a successful and respected industry,” and “to promote the image of the metal roofing and cladding industry and the use of its products.” We look forward to tracking and reporting on the progress of the SAMCRA.
Another highlight in this issue is an article by Professor Kayvani, of Aurecon, who addresses a number of interesting aspects pertaining to the design of world-class stadia, “including technical and commercial considerations to ensuring game-changing sporting facilities.”
Last, but certainly not least, ArcelorMittal SA graces our cover this month and shares accessible and detailed information on the Chromadek® range.
In our April issue of the SA Roofing magazine, you can look forward to more roofing highlights that include, among other features, a focus on waterproofing and associated products, services and projects.

“As construction Health and Safety practitioners, we tend to look mainly for non-compliance legal issues which, in this incident, appear to be many. But we should also be looking deeper into the root causes, such as the issues of designer competencies, construction programmes, selection of contractors, and the competency and extent of authority of construction supervisors,” Michell adds. “A tragic event like this will have repercussions dealing with quality issues in general and the possible long-term safety of the tenants of other completed buildings.”
“The tragic collapse of the mall left two people dead and 29 injured, and placed an undesirable discredit on the entire construction industry,” Michell states, noting that there was no Master Builders SA member involved in the construction of Tongaat Mall.
Phumudzo Maphaha, the Department of Labour’s Manager of Occupational Health & Safety: Construction, has been appointed Presiding Inspector for a Section 32 hearing. Section 32 inquiries are usually appointed by the government against parties whose negligence results in occupational injuries and death of workers.
“According to reports, the developer, when interviewed after the accident, suggested that it was ‘normal’ practice for developments to begin before proper permissions are secured. However, until the findings of the high-level government investigations are published, we can only speculate regarding
the causes of the accident, but there have been reports that suggest that construction continued despite a procedural work stoppage ordered by building inspectors. Eye-witness accounts also suggest that there was no form-work in place below the concrete slab and a site worker, who escaped injury, allegedly stated that there was no scaffolding in place under soft concrete.
Michell says the proposed amendments to the government’s Construction Regulations will require that a client applies for a construction work permit before
work can be commenced. “But the question remains whether the municipal, building and construction regulations and permits now in place will avert a similar incident in future. Because of the additional prescriptive requirements, unscrupulous contractors may be encouraged even more to avoid bureaucratic ‘red tape’ by providing generic documentation that will not address the relevant issues the regulation calls for. The intention of the construction work permit is for relevant baseline risk assessments, and specific health and safety specifications, to be submitted with the application for the construction permit,” Michell adds.

The source of this power is found mainly in the form of temporary electrical installations on a site.
The safety process regarding temporary electrical installations starts with the appointment of a competent person in writing. The responsible person must control all aspects of these installations.
It is the function of this appointed person to install all the temporary installations in terms of the required standards and regulations and to issue the principal contractor with a Certificate of Compliance, commonly known as a COC. This person must also inspect the temporary electrical installations after the installation and then on a regular basis. These inspections should include the testing of the earth leakages that are found in the temporary DB boards. The findings of the inspections must be recorded on a register and be kept on site.
All DB boards must be correctly colour-coded, numbered and have the correct electrical symbolic safety sign on them. The DB must be accessible and the area around the board must be free from rubble and material. The DBs must be fitted with doors that must be kept closed at all times, as well as suitable inside cover plates. All unused slots must be blanked off and all switches and circuit breakers must be identified and functional. The DB must be fitted with an earth leakage unit that is functional, as well as a main switch that must be accessible. Finally, there must be suitable access for the portable electrical tool cables and extension cords for when the doors are closed.
All temporary wiring and extension cords must be properly insulated and all plugs must be fitted correctly. Remember, “Brown is live, blue is not, green and yellow earth the lot.” All cables must be protected from mechanical damages and moisture. Plug points should never be overloaded or exceed the circuit breakers’ rating. All light fittings and lamps must be protected from mechanical damage and moisture.
All electrical machinery and tools on site are also to be checked by a competent appointed inspector, and due to the high risks involved with electrical tools, visual inspections are to be done on a daily basis.
All portable electrical tools and extension cords must be identified and numbered and thereafter recorded on a register. Formal inspections must be conducted monthly and findings of these inspections are to be recorded in a register, which must be kept on site at all times.
Make sure that portable electrical tools are always in good condition. The cable must be insulated with no unsafe connections. Do not use a tool if you are not trained to use it and/or if it is unsafe, especially if the casing is damaged. Make sure that the plug is fitted correctly and that the earth wire is secured. Only if the tool is marked with a ‘Double Insulated’ sign does it not required to be earthed.
Remember, although electricity is a very useful source of power it can be fatal if not used correctly.

HISTORY
In October 2012 Eben Nel, Director at Global Roofing Solutions, convened a meeting to explore the possibility of forming an association to represent the metal cladding industry in South Africa. This association was to be known as the South African Metal Cladding and Roofing Association, SAMCRA.
The meeting was attended by representatives from thirty nine companies, which included producer mills, roofing profilers, roofing contractors, suppliers of fasteners, ventilators and other ancillary items, together with delegates from allied associations and institutions.
Following the discussion, it was agreed to form a committee that would consolidate the ideas and proposals presented at the meeting, as well as draft a basic structure for the association.
During this process it was realized that for the association to realize its goals it would have to interact with a number of national and professional bodies on a highly technical level and it was decided to approach the Southern African Institute of Steel Construction, SAISC, with the prospect of SAMCRA becoming a sub-association similar to that of SASFA, the Southern African Light Steel Frame Building Association.
Today SAMCRA, with a minor adjustment of its name to the Southern African Metal Cladding and Roofing Association, is proud to be a sub-association of the SAISC.
REGULATION & PROMOTION OF INDUSTRY
Metal cladding in one form or another is utilized in just about every aspect of building and construction. According to Stats SA, metal cladding constitutes 63%, by value, of the total South African roofing market. The metal roofing market in South Africa basically comprises two sectors, formal and informal.
The formal sector is partly regulated by the professionals responsible for the design and national bodies, such as the NHBRC. Unfortunately, identification of the base materials and finished products is not regulated, which provides an opportunity for unscrupulous parties to substitute inferior materials, which initially may look like the specified product, but, after a relatively short period in service, suffer storm damage and/or advanced degradation of the protective coating. In the informal sector, price is paramount with almost no consideration being given to the structural performance and durability of the product.

In order to address this problem, SAMCRA will promote the exclusive use of products that are branded by the producer of the coil. The branding will contain the thickness and grade of the steel core, plus type and thickness of the protective coating. This facility is already available from reputable producer mills. In addition, manufacturers will have to publish performance tables, derived from testing conducted at an approved independent test centre.
SAMCRA is actively involved in the final drafting of a SANS code for roofing, an initiative instigated by the SAISC some time ago. We are also participating in the drafting of other regulatory documentation.
SAMCRA’S MISSION
To create an infrastructure on which an orderly industry can be built, including appropriate standards, testing facilities and a base of knowledgeable people.
To facilitate the fusion of the ambitions of the metal cladding and roofing industries with the requirements of the specifiers and clients to create a successful and respected industry.
To promote the image of the metal roofing and cladding industry and the use of its products.
THE INDUSTRY
In essence, we believe that with the right guidance and initiatives, the cladding industry will not only provide an economic, durable and efficient protective envelope to buildings, but will also become respected for its pursuit of excellence and integrity.
As the association will draw its membership from a broad spectrum of parties involved with the construction industry, including financiers and insurers, coupled with its link to the SAISC, it will provide an extensive pool of knowledge to specifiers and developers. It will also have credible access to specifying authorities and professional associations.
EDUCATION & TRAINING
Education will certainly form a big part of SAMCRA’s initiatives. We plan to hold a number of workshops on various aspects of cladding.
LOOKING AHEAD
Central to the goals of SAMCRA will be the establishment of an accredited testing facility to verify the performance of products, the creation of a successful campaign to have all metal cladding products sold in South Africa branded with the relevant product information, provide information to specifiers, building inspectors and other decision makers and to facilitate training for all with particular focus on artisans, the implementation of a programme to certify roofing contractors and a programme to have ‘roofer’ recognised as a trade.
Founder members of SAMCRA include ArcelorMittal SA, BlueScope Steel, BSI Steel, Clotan Steel, Global Roofing Solutions, Heunis Steel, Macsteel Roofing, Pro Roof Steel Merchants and Safintra.

CHROMADEK®
Consider for a moment what a roof really does. It is not something that we think about often, but what really comes to mind is the protection a roof provides from nature’s elements while adding the finishing touch to a building. When it comes to making a roofing choice, what better way than to finish your home or building with Chromadek® - designed for both form and function. Developed in 1976, this well-known roofing range, Chromadek®, has been refined and enhanced by ArcelorMittal and features 14 versatile colours inspired by nature to complement your choice in building. To give you an idea of what goes into Chromadek®, think of a profiled steel sheet containing a unique corrosion barrier of zinc applied through the process of galvanising. Furthermore, a final coat of colour is applied, sealing the unique identity of Chromadek®, making it the preferred roofing choice. Chromadek® is further enhanced through a range of heat reflective colours that reflects more of the sun’s energy, preventing the coating from absorbing energy.
WHAT MAKES CHROMADEK®’S PAINT SYSTEM UNIQUE?
Significantly, 50% of the sun’s energy is invisible, extending over three light spectra, while 5% of the light spectrum presents itself as invisible ultraviolet light. While 5% might seem very small when translated to coating degradation, this small value becomes significant. About 4% of solar energy is present in the visible region at ground level, implying that a staggering percentage of more than 50% of solar energy is found in the invisible infrared region. This results in a high volume of energy that is absorbed by the coating, which results in fading of the coating. Designed to overcome this, the heat reflective pigments present in heat reflective Chromadek® are chemically inert and highly stable, meaning that heat reflective Chromadek® reflects more of the sun’s energy to prevent the coating from absorbing energy. This effect translates to less heat build-up, longer lifecycles and less fading in comparison to alternative roofing options.

HEAT REFLECTIVE CHROMADEK®
As part of the development in green and sustainable building, a prominent feature of heat reflective steel roofing is a lower energy demand. Through the heat reflective pigment embedded in Chromadek®, the benefit of reduced heat transfer can be realised, as less energy is required to lower or regulate the temperature of a building.
While paint fading is part of the predictable lifecycle of a paint system tending toward its natural state, the increased Total Solar Reflectance (TSR) threshold for Chromadek® ensures that the fading will not occur prematurely. A collaborative approach between ArcelorMittal South Africa and its paint suppliers has led to the continuous improvements in paint performance of Chromadek®.
A prime example illustrating the enhancements made to Chromadek® can be seen in the Colour and Gloss retention results after four years of exposure at St Helena Bay on the West Coast, for Traffic Green which represents a popular Chromadek® colour choice.
AN EXCITING NEW DEVELOPMENT, CHROMADEK ULTIM®
While Chromadek® is intended for use in rural, mild chemical and moderate marine conditions where correct application and maintenance will guarantee an exceptional lifespan, an exciting new development in colour coated steel roofing sees the introduction Chromadek Ultim®.
Chromadek Ultim® is both versatile and functional, designed for applications in either marine or heavy industrial conditions, and comprises a Z275 hot-dipped galvanised substrate, pre-primed with a chrome-free primer and finished with a final coat on the top surface, giving a total thickness of 38 - 42 µm. The reverse surface is coated with a 10 µm corrosion resistant chrome free primer and a 10 µm top surface paint system.
Chromadek Ultim® is the ideal choice for coastal applications up to 400m from the high water mark. This ultimately enables colour coated steel roofing to be applied in one of the most demanding environments in South Africa.

The development, undertaken by Billion Group and Abacus Asset Management, started in June last year and is on track for completion in March 2015.
Uitenhage-based steel company, Uitenhage Super Steel, is preparing to put up the mall’s 1,200 ton roof structural support, while Durban-based company Browndeck Roofing is set to lay the 380 tons of roof sheeting – spanning about 70 000m² in area – from April.
Browndeck Roofing owner, Richard van Heerde said the company had shipped in pre-coated steel coil from Malaysia.
“The sheets will be rolled and formed on site,” Van Heerde said. “We will start in early April and hope to be finished during August.”
To lay the roof sheeting, insulation, flashings and 3 000m of gutters, a team of about 20 would fly to Port Elizabeth from the Durban office. They would be supplemented by an additional 40 workers, all dedicated to completing Baywest Mall’s roof, he said.
By mid-2014, about 2 000 workers – from carpenters to bricklayers – will be feverishly working on site.

Basil Read, which has been awarded the tender for developing a R300-million road network around the mall by the SA National Roads Agency Ltd (SANRAL), commenced work in January. Already, principal contractor, Murray & Roberts has commenced with laying the concrete slabs, which form the upper level of the mall. Once complete, about 60 000m³ of concrete will have been thrown.
From February, work on the mall’s roof will commence. About 5 000 tons of reinforcing steel will be used on the centre, as well as a further 1 000 tons of structural steel.
Come October 2014, work on the final stages of the mall will be under way. The landscaping is scheduled to start by the end of that month, while the 250 shops will start being fitted. The mall will boast about 3.5km of shop fronts and a mammoth 35km of electrical cabling.
“Everyone has done a remarkable job on getting the mall started,” said Baywest MD, Gavin Blows. “We are extremely excited to be able to bring what will be a unique shopping experience in South Africa to the Eastern Cape. Before we know it, Baywest will be open for business and changing the way people think about the Eastern Cape.”
Blows said the community’s excitement ahead of the mall’s opening, and the injection of the mall’s development into the local economy by creating 3 000 direct jobs and up to 7 000 indirect and induced jobs, made Baywest an invaluable asset.
The mall forms the first phase of the larger Baywest City precinct, which Blows said would become “the Century City (in Cape Town) of the region.”

Man has used asbestos for centuries, as it has good sound absorption, thermal and a high tensile strength properties, coupled with resistance to fire and
chemical damage. As asbestos is abundant and is easily mined, it was therefore a cost-effective ingredient in numerous building materials. Despite these positives, asbestos is a dangerous mineral which can cause serious illness, such as malignant lung cancer, mesothelioma, and asbestosis. The longer a person is exposed to and inhales asbestos fibre, the greater the risk of developing one of these illnesses.
South Africa is one of the many countries that has banned asbestos, but the mineral still leaves behind a deadly legacy.
Many of these asbestos products would have experienced varying levels of 'wear and tear' over the years which could lead to structural breakdown, thereby releasing asbestos fibres into the environment.
OVER-SHEETING:
Over-sheeting is an environmentally sound way to deal with roof panels that contain asbestos.
The added benefits of over-sheeting a roof are numerous, especially when you consider the cost savings for heating and cooling. The extra layer automatically increases your ‘R’ Value, providing insulation to heat lost and ingress. Over-sheeting allows you to give your building a facelift without the need to remove your existing roof.
Over-sheeting, in conjunction with the encapsulation of the raw asbestos carrying board, contains the asbestos roof without the need for expensive and potentially hazardous removal, coupled with the environmentally sensitive dumping of the material.
WHAT ARE THE BENEFITS OF OVER-SHEETING COMPARED TO STRIP AND RE-SHEETING?
1. MINIMAL DISRUPTION TO BUSINESS OPERATIONThe existing roof remains in-situ whilst the new environmentally sound and energy efficient roof is installed, allowing for normal day-to-day business operation in the building below. (Depending on the condition of the existing roof sheeting).

2. UPGRADING THE ROOF TO AN ENERGY EFFICIENT ROOF SOLUTION Upgrading or increasing the roof insulation creates a thermal barrier to the elements, reducing the rising on-going operational costs of heating and cooling.
3. SAVE THE RISING COSTS OF STRIPPING AND DISPOSAL OF THE ASBESTOS ROOFNo requirements to strip off the existing asbestos roof sheeting, therefore saving transportation costs and associated carbon emissions, along with the rising costs of disposal.
4. SAVE ON LABOUR COSTS AND TIME No requirements to remove the existing asbestos roof sheets, therefore over-sheeting saves time to install the new over-roofing system.
5. IMPROVED HEALTH AND SAFETY ON ROOF INSTALLATION The existing asbestos roof remains in place and can provide a platform to install the new over-sheeting system. By not disturbing the existing roof sheets, you minimise the opportunity for potentially hazardous particles to become airborne.
6. INCREASED ROOF INTEGRITYInstalling the innovative Ashgrid Bar & Bracket grid system, fixed through the trough of the existing roof sheet into the structure, provides additional lateral restraint.
7. UPGRADING AND ENHANCING THE APPEARANCE OF YOUR BUILDING Along with the opportunity to upgrade the performance of your roof system to save you money every day, over-sheeting allows you to enhance the appearance of your building at a relatively low price.
INSTALLATION OF AN OVER-SHEETING ROOF SYSTEM:
Existing asbestos roof in readiness for over-sheeting can provide a safe working platform to work off during installation of the new roof. MRC’s specially formulated lacquer is sprayed or brushed on to encapsulate the existing roof sheet.
MRC uses the innovative Ashgrid Bar & Bracket system to create the correct space for the installation of insulation to suit the required U-Value. Brackets are supplied from 60mm to 300mm in 20mm increments.
The Bar & Bracket grid system is installed in the troughs of the existing asbestos roof sheet with the brackets fixed through the existing roof sheet into the hot rolled angle purlin, throughout the roof area.
NB* The bracket centres are determined by the local wind and new roof loads.
Generally glasswool or mineral fibre insulation (Class A – non-combustible & A1 – spread of fire, the best in both cases) are installed to suit the roof specification. The insulation aids to keep the heat or cool air out and the cool and the heat within the building, therefore reducing the building’s operational costs.
The roof sheet can be supplied in a range of profiles, materials, finishes and colours to suit the aesthetics, budget, and project requirements.
MRC high quality fasteners are used throughout the roof system and installed in the correct positions to suit the specified roof system and the project loads.

• Design flexibility• Environmentally sustainable• Lightweight• Efficient build time• Consistency of quality • Cost-effective solution
As its name suggests, a light-steel frame (LSF) building consists of a framework of structural wall frames manufactured from cold-formed, light-gauge, aluminum zinc steel or galvanized steel sections.
This framework is then cladded on the exterior in single-skin brick or a layer of fibre cement board, and on the interior using plasterboard or fibre cement board.
Electrical and plumbing services and insulation are installed in the convenient wall cavity created by the light steel frame. The roof structure consists of a framework of lightweight, aluminum zinc steel or galvanized steel trusses, cladded in similar coated steel.
Because the basic structure of a light-steel frame building is pre-fabricated, one can expect a consistent quality and an assembly speed that far surpasses that of traditional building techniques.
With the mass of a light-steel frame wall amounting to less than 10% of a double-skin plastered brick wall, it follows that transport costs are also substantially lower.

There is also far less material wastage on site and associated costs of hauling them away on completion of the project. With these factors translating into an average cost saving of around 20%, light-steel frame building is an option that’s well worth considering for both new and retrofit low-rise builds – including the affordable housing market.

“From a place to see your favourite athletes pitting their skills against competitors, to a modern Roman Colosseum where the public gather, clutching smart phones, for a multimedia and multi-sensorial experience!”
In this article, Professor Kayvani explores some of the key aspects of designing world-leading sports stadia, including technical and commercial considerations to ensuring game-changing sporting facilities.
DESIGNING WITH LEGACY IN MIND
While a world-class stadium project is often driven by a short-term need to stage an important event, such as the FIFA World Cup™ or the Olympics, far more attention is now being paid to maximising the sustainable legacy of these structures, bearing in mind the huge investment and upkeep they require. Successful world-leading stadium design means thinking beyond the obvious and certainly beyond the main prestige event. While first and foremost, we have to meet the client’s brief to accommodate the global event, the outlay is often in the hundreds of millions of dollars and a true legacy design involves maximising the stadium’s usage.
In fact it is generally better to start the concept stage of design from a legacy point of view – what will happen after the main event? – while also ensuring the stadium will meet immediate objectives. For instance, there is the urban development potential that must be evaluated: urban stadia are anchor projects with the power to transform a precinct or renew it.
An impressive current example of this is the Perth Arena, an entertainment and sporting arena in the city centre of Perth, and the centrepiece for the redevelopment of the Northern part of the central business district.
CREATING ICONIC ARCHITECTURE
While it’s generally accepted that stadia are often status symbols for a city, region or nation, the drivers vary on a case-by-case basis. For example, while the Beijing Olympics projects were strongly influenced by iconography and the big event itself, the Sydney and London Olympics sports facilities were more driven by legacy planning.
In terms of status, a building that accommodates tens of thousands of people is inevitably a large structure and a dominant feature on the landscape. This presents an opportunity for iconic architecture expressing how a region and the nation want to project themselves.
Aurecon collaborates closely with the owners, architects, contractors, and the rest of the project team to achieve iconic structures in an economically and environmentally responsible manner.
Furthermore, Aurecon believes stadia should become impressive status symbols – not just in their architecture, but also in their engagement with the fans and the public – and remain so for decades to come.

SUMMITING THE ROOFTOP CHALLENGE
A stadium’s roof is often a demanding structure to design and build, requiring a significant architectural and structural engineering effort.
Collaboration is key: architectural expression and beauty must meet engineering requirements of strength, serviceability, and durability.
The structural engineer, in particular, needs to take a very proactive, yet collaborative approach to achieve the overall architectural vision within budget and in a buildable form.
There is no absolute right or wrong roof form. What is architecturally stunning with the right functional geometry is one thing, and what works efficiently is another. However, great holistic design outcomes are often achieved when key aspects of structural efficiency, architectural expression, and functionality are carefully considered in an integrated fashion.
For example, the decision on the variations in height, depth and profile of the roof is as much about achieving structural efficiency as it is about architectural expression and aesthetic proportions, and also maintaining the view of the field and scoreboard from the upper tiers.
These days we design stadium roofs in an excitingly diverse array of structural forms, ranging from the rather conventional cantilevered and long-span systems to the more exotic shells, cable nets, and ‘tensegrity’ roofs.
The choice of appropriate construction materials and their correct application is particularly important. Long-span structures are generally fabricated from steel, because of the high strength-to-weight ratio, ease of use and cost effectiveness of this material.
The search for lightweight, durable cladding materials has resulted in the increasing use of high-tech tensile membrane systems.
The decision on whether to incorporate a fixed or a retractable roof requires the holistic evaluation of the value in weather protection versus turf health, and the impact of shadow effects on spectator viewing and TV broadcast quality – all factors that have implications on cost, risk, functionality and potential return on investment for the project.
Elaborate roof designs need careful assessment of wind loads on the structure, while the overall design has to ensure that spectators are comfortably shielded from wind.
Aurecon’s capabilities in building and analysing simulated models enable us to overcome the unknowns in an unconventional design and ensure that project objectives are fully met.
In essence, we can test the building and de-risk it before it is built, without compromising its technical integrity.

ANSWERING THE NATURAL TURF TREND
To sustain healthy, natural grass means designing for lengthy periods of exposure to sunlight, which creates a roof opening optimisation conflict. Too small an opening, while shadier for the spectators, leads to a significant expenditure for annual turf repairs. Too small a roof results in disgruntled, wet spectators during rainy spells.
One form of a solution is the roof of the Forsyth Barr stadium in Dunedin, New Zealand. Membranes of Ethylene tetrafluoroethylene (ETFE), a fluorine-based plastic, were used to create air-inflated pillows as the roof cladding material in what has become the world’s first fully enclosed grassed stadium.
Aurecon used advanced modelling and simulation techniques to verify that the adequate air ventilation and sunlight exposure can be maintained for grass health within the fully covered stadium. The solution was subsequently recognised with a Merit Award in the 2013 Association of Consulting Engineers New Zealand Innovate NZ Awards of Excellence.
Melbourne’s 55 000-seat Etihad Stadium is one of Australia’s leading multi-purpose venues catering for major sport and entertainment events.
Its natural turf is maintained in a healthy condition through the stadium’s fully retractable roof that takes only eight minutes to close.
As part of the turf management process, localised grow lights are utilised, particularly on the higher wear areas over the pitch. This combined strategy has delivered high quality grass despite the busy event schedule of this world class stadium over many years.

ENSURING MULTI-USE FUNCTIONALITY
Increasingly, stadia must be adaptable, high performing buildings that achieve multi-use functionality.
The trend is for physical flexibility, which means designing to be able to shrink capacity using modular and demountable construction.
Upper tiers and even upper structures can be removable. While this appears straightforward structurally, one of the challenges is that building services also need to be modular and demountable.
An elegantly simple solution in some arena-type venues, such as the Perth Arena in Australia, is to have curtains that can close off the back tiers seating to create a cosier ambience during smaller events.
The vibrations induced by crowds’ synchronised motions need to be carefully studied in the design of the seating tiers. These days we use sophisticated analytical tools to predict the expected level of accelerations at every seat on the tier to ensure the acceptable thresholds are not breached in lively sports and concert events.
HIGH-TECH THINKING
Technology and fan engagement will be the key in the future. Whether it is through additional in-game augmented reality content delivered directly to spectators’ smart phone applications, enhanced pre- and post-match family orientated entertainment produced by in-house production teams, or unique rewards for attending matches, such as special food and beverage incentives, the final end game is to draw fans away from their living rooms and into the stadium.
A key trend in leading stadia is high-tech with WiFi that will allow fans to use their own smart phones. Technology is racing ahead and soon the use of multiple cameras and more sophisticated broadcasting technology will enable fans to select and track the activities of their sports idols on their smart phones.
In addition, advances in computer technology are quite literally breathtaking and will mean modelling techniques, such as Building Information Modelling (BIM), Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are becoming ‘business-as-usual,’ extending the boundaries of structural form and architectural expression ever more rapidly.
These techniques are, at the same time, ensuring safety and promote time and cost savings.
Increasing attention is being given to sustainability aided by the strength of our modelling capabilities. This will be reflected in stadia consuming less area and tonnage of material, on-site power generation with photovoltaic arrays on the roof, grey water reuse, thermal storage, and a stronger focus on carbon neutrality.
MEETING TIGHT TIME AND BUDGET CONSTRAINTS
We are always very aware of the need to deliver on time, on budget and manage the risks to the client in doing so.
The fact that a stadium is an unusual building and an increasingly complex form with many components means the risk of exceeding time and budget is often very significant.
Effective management of the planning of design and construction is vital. A project team is required to have an in-depth understanding of how the decisions they make impact on cost and programme and how factors, such as supply chain and the need for any specialist skills impact on project delivery.
CREATING FAN COMFORT
The current stadium design buzzword is ‘Fan First.’
We have a role to play in delivering stadium projects that encourage fans to leave their comfortable couch and big screen TV, and look forward to having a great time in the stadium. This means considering what makes the experience at the stadium as good as it can be for the fans.
The key word here is ‘comfort.’ Today, not only is shading a given, but increasingly air conditioning and cooling have to be provided.
We have been developing concepts, such as the installation of cooling pipes in the concourse slabs and displacement air-conditioning delivered via plenums under seating platforms throughout the stadium as a sustainable way of achieving a comfortable environment.
Even the layout of the premium seats is influenced by the need to facilitate delivery of food and refreshments, so that well-heeled fans do not to miss any action by having to leave their seats for refreshments.
We’re also seeing a big push in parts of the world for localised produce and gourmet food to be sold in and around the venues, rather than your standard pie and chips. These creature comforts, integrated with an in-seat food and beverage service smart phone application, provide a unique stadium-only experience that cannot be replicated at home.

The new product is Armodillo, a multi-functional polymer-bitumen membrane that offers waterproofing, drainage and the protection of foundation walls in a
single product application.
a.b.e., part of the Chryso Southern Africa Group, signed an agreement with Index in 1996 and recently celebrated the sale of 2 million rolls of the Index bitumen waterproofing membranes in South Africa.
Lance Anderson, a.b.e.’s Brand Manager: Waterproofing, says, “Index’s new Armodillo Polyester membranes, which incorporate anti-root protection, can solve the problems of waterproofing, mechanical protection, and drainage – all in one product.”
“Armodillo’s upper face is armoured with impact-resistant, elastic polymer-bitumen ‘dimples’ or bubbles – similar to the
protective plates of an Armadillo’s shell – that protect the membrane from perforation when buried, and at the same time form an efficient drainage network that allows any water to quickly drain to the perimeter drains, stopping hazardous pooling. If the dimples are torched, they become adhesive, making it possible to bond insulating panels, non-woven fabrics and other materials onto the membrane.”
“The lower face of Armodillo membranes is covered with Flamina, a plastic film that can be easily torched. The bubbles on the Armodillo membranes keep the installer’s hands away from the torch, making installation much safer and easier. Index Armodillo can be installed by bonding the next membrane onto the 70mm indented selvage of the previous membrane, ensuring that no raised, uneven, problematic laps are created,” Anderson adds.

“Interbuild Africa has undergone extensive rebranding,” says Gary Corin, Managing Director of Specialised Exhibitions Montgomery. “This transformation includes extensive changes to the show’s format, all aimed at delivering an event that provides our exhibitors with maximum return on their investment, while bringing our visitors a show that is highly relevant in exhibitor and information content,” he says.
Some of the major features planned for 2014 include a skills development competition, free-to-attend seminars, a glass conference and a building conference in partnership with some of the industry’s major associations.

TS Interbuild Africa 2014:
Africa’s most iconic building exhibition has undergone a complete renovation
MARCH 2014
Interbuild Africa is one of the largest building and building services exhibitions in Africa. With a history spanning over four decades, it has also become one of the most well-known events of its kind in Africa.
42
As Africa’s definitive building and building services exhibition, Interbuild Africa provides exhibitors with an unparalleled opportunity to seize the local market. As one of the longest standing and leading exhibitions in the building sector, Interbuild Africa provides exhibitors with an unrivalled platform to meet new and existing customers, launch new products and services and build up an enviable list of new sales leads.
The focus across Interbuild Africa 2014 is around the latest industry developments and the extensive range of products
available in the local building and building services arena. Interbuild Africa and co-located shows – Glass Expo Africa, Plumbdrain Africa, EcoAfribuild, Woodpro Africa, Current Africa and Hardex Africa – constitute the biggest building and building services exhibition in Africa. The combined shows will provide some much needed support to the local building industry by creating an enabling environment for business networking, product and equipment purchases and business development.
“This year Interbuild Africa will focus on solidifying support from some of the leading associations and institutes in the industry,” says Corin. “This will ensure that Interbuild Africa delivers an event which is relevant, valuable and, most importantly, meets the expectations of exhibitors and visitors.”
Interbuild Africa 2014 will showcase the latest innovations, products and developments that exhibitors across the building and building services industry have to offer, including all aspects of interior and exterior building design and products across residential, commercial and industrial development. For exhibitors, Interbuild Africa is an excellent results-driven opportunity to reach the greatest number of decision-makers.
“Riding high on the success of the 2012 show, which welcomed more than 9 000 visitors, we are taking Interbuild Africa 2014 to the next level and building the best show that the industry has ever seen,” says Corin. “We are upping the standard this year and look forward to exceeding everyone’s expectations at a show that will not only deliver an excellent return on investment for our exhibitors, but also provide a first-rate experience for all our visitors,” he concluded.
Interbuild Africa 2014 will take place from 20-23 August 2014 at the Johannesburg Expo Centre in Nasrec. For further information or to book your stand, visit www.interbuild.co.za.

Sika AG is a globally active specialty chemicals company, which has its South African Head Office in Durban, along with branches in all major South African cities.
Bolstered by a late European winter, Sika AG's sales picked up momentum in the 4th quarter of 2013. Total sales grew 9.4% in European currencies in the 2013 financial year. Adjusted for exchange rates, sales were 6.5% higher at CHF 5.14 billion. This positive development is largely due to organic growth. The rapid integration of acquisitions also helped to drive growth momentum.
5.9% of the overall sales increase reported in the 2013 financial year was attributable to organic growth, to which all regions contributed. Acquisition-related sales growth came to 3.5%. The strong Swiss franc produced a negative currency effect of 2.9%. This resulted in 6.5% sales growth in Swiss francs. In light of the demanding conditions prevailing in numerous markets, the results achieved bear testimony to the strength and robustness of Sika's growth strategy.
The region EMEA (Europe, Middle East, Africa) reported 8.5% growth for 2013. This positive trend was driven primarily by organic growth in Eastern Europe, Africa, the Middle East and the UK, as well as by acquisitions.
Business in the region North America picked up considerably toward the end of the year, resulting in a 2.3% increase in sales for 2013. While the residential real estate market recovered, any positive impact on the rest of the construction industry remained modest.
Latin America posted the strongest growth of all regions in 2013. Year-on-year, sales were 15.1% higher, with every country and target market recording increases.
With above-average growth, the region Asia/Pacific also saw sales rise by 12.5%. The OECD countries reported increases in the single-digit percentage range, while China, India, Indonesia, Thailand, Malaysia and Vietnam all posted double-digit growth rates.
The accelerated build-up of business in the emerging markets produced sales growth of 17.2% in local currencies and 11.8% in Swiss francs. The proportion of sales generated by the emerging markets increased to 38% (previous year: 37%).
Through investments in emerging markets, the launch of new products, and the acquired companies, Sika is poised to continue its growth strategy in the current year 2014. That being said, the significant currency movements witnessed in the past few months and the process of integrating the newly acquired companies present a challenge in terms of sales growth and costs items.

Deon Landmann, Education, Training and Transformation Manager of MBA North, says the Association has arranged for the
specialist consultancy, mPower Ratings, a SANAS and IRBA Accredited Verification Agency, to present the affordable half-day seminars as long as there is demand in 2014.
“The Revised B-BBEE Codes of Good Practice have produced a substantial amount of confusion among companies, including MBA North members. The revision has, therefore, sparked off an increase in training offered by the private sector – sometimes at exorbitant prices. MBA North has arranged for mPower Ratings to present the half-day seminars at a venue to be arranged with the agency. The provisional date for the first course is March 10, 2014.”
“The Amended Codes were gazetted on October 1 this year and grant entities a 12-month period in which to use the old Codes, after which the Amended Codes have to be implemented. The Amended Codes are in many respects substantially more challenging than the old ones, an indication of government’s resolve and determination to make transformation more effective.”
“October 2014 is not too far away and MBA North strongly suggests that its members familiarise themselves with the new requirements as soon as possible,” Landmann adds.
Among the revisions in the Codes is the discounting of BEE status level for companies that fail to achieve a stipulated threshold, and the overall black compliance targets to be broken down into sub-targets for different ethnic groups and weighted in accordance with equitable representation as per the Employment Equity Act. “But these are just two of a myriad of changes, some of which are not straightforward and are still being studied and interpreted even by authorities on the subject.”
More information about the training arranged by MBA North can be obtained from Sarah Mnyandu on 011 805 6611 or [email protected].

Deryck Spence, executive director of SAPMA, says this is only one of many potential opportunities various departments of government could utilise to train the
unemployed and reduce joblessness in South Africa.
SAPMA has suggested to the consultants entrusted with the redeployment of Medupi workers that SAPMA and its training arm, the SA Paint Industry Training Institute (SAPITI) could develop a special curriculum, covering one day of theoretical and four days of practical training, for ex-Medupi workers.
“The course, although basic, will nevertheless be comprehensive enough to help successful students gain employment in the paint contracting sector after which they could strive to attain full qualification and expand experience and training to entrepreneur status and starting their own businesses,” Spence explained.
SAPMA has offered to provide special cut-price training and accommodation for a ‘trial team’ of 10 Medupi candidates facing redeployment who would then afterwards become promoters of the training available at the Centre of Excellence to work colleagues and potential candidates.
A delegation of the Construction Industry Development Board (CIDB) also recently visited the Centre of Excellence training facility and was, according to Spence, exceptionally impressed and motivated to assist in the future growth of the Centre.
“The delegation met the residents of an Ekurhuleni informal settlement who attended a free course in basic paint application provided by SAPMA. The CIDB executives were touched by the passion and determination of these jobless disadvantaged people, of which five were women, to learn new skills to earn a living.
“With SAPMA’s help, the eight students have already found contractual employment and their success has inspired SAPMA to consider compiling a list of Centre of Excellence-trained paint contractors for use by the public and relevant organisations seeking qualified painters.”
But Spence says the Centre of Excellence critically needs support from governmental bodies, as well as the coatings sector to become viable this year. “Despite the fact that the Department of Trade & Industry has called for a strong
working relationship between the private sector and the government in terms of its National Industrial Policy Framework and the five facets of the government’s Industrial Policy Action plan, there has so far been no tangible support from state departments to the SAPMA training on offer. SAPMA has, for example, invited the Department of Labour, the Department of Public Works, and the Department of Correctional Services to send students to the Centre of Excellence. To date, we have had no reply,” Spence adds.
SAPMA offers to turn redeployed Medupi workers
into budding paint contractors
A CIDB delegation met the residents of an Ekurhuleni informal settlement, such as Ntebo Nqozwana (pictured), who attended a
free course in basic paint application provided by SAPMA at the new Centre of Excellence in Springs.
The new training facilities for aspiring paint contractors at the SA Paint Manufacturing Association (SAPMA) Centre of Excellence in Springs could provide essential training for the hundreds of workers who will be jobless
after the completion of the Medupi Power Station.

The courses will all be presented at SAPMA’s new training facility, The Coatings Industry Centre of Excellence, in Springs, but in-house training options, as well as
formalised training in selected Cape Town, Durban and Port Elizabeth venues will also be available for some of the courses.
SAPITI WILL, DURING THE FIRST HALF OF THE YEAR, OFFER TRAINING IN:
• Paint Technology Qualification• Raw Material Preparation Skills Programme (CHIETA
Accredited NQF 2 level)• Decorative Retail Theory Programme• Applicator Skills Programme
In the field of technical training, SAPITI will offer Surface Coatings Technology Part 1 – for staff working in a QC lab, technical sales reps and raw material supplier reps. This course includes subjects such as Basic Technology, Application and Evaluation.
Also on offer will be Surface Coatings Technology Part 2 for staff whose careers are focussed on product development or formulation, technical support, trouble-shooting and problem solving. Here, the curriculum includes Surface coatings Technology Part 1, Pigments, Modifiers, Solvents and Binders, Convertible Binders, and Formulating Principles, formulation including project management.
The Paint Technology Qualification course offers industry-specific training modules and technical qualification for staff following a technical and sales career (sales reps NQF 4 to 6). The course started in Johannesburg and Durban in February and will be offered in Cape Town and Port Elizabeth in May. It includes 11 elective modules.
Raw Material Preparation Skills (CHIETA NQF 2) is ideal for plant operators, assessor trainees, supervisor trainees, labelling and packaging staff, and raw material warehouse staff, among others. Contact SAPMA for dates of this training for this five-day course starting in Johannesburg from March 4 which can also be presented in-house.
The Decorative Retail Programme (NQF 2) started in Johannesburg at the beginning of this year and the five-day course could also be offered in other cities depending on demand. It is ideal for sales and DIY personnel, owners and supervisors of applicator firms, and non-technical staff wanting to learn more about preparation of surfaces and application of paint.
In-house training is also available for Applicator Skills Programme (NQF 2). This course offers theoretical and practical training sessions followed by workplace training.
The SAPITI training programme for the second half of the year will be announced later.
