EDITOR’S COMMENTS

No intermediate scale Welcome to the April 2014 issue of the SA Roofing magazine.

his issue highlights roofing and its supporting components in a variety of ways; from a breathtaking glazed shopping centre, to a unique fishing museum in Maputo that showcases timber trusses and roofing in impressive size, backed by intricate and specialised planning and detail. Big is better with Emporia shopping centre, whose aesthetics and pure scope were architecturally underpinned by the motto, ‘No intermediate scale.’ This project stands testament not only to the workability of the materials employed, but to the sheer size, scale and visual impact of a roof and cladding that seem almost woven into one. This mall even boasts a rooftop terrace of almost 30 000 m2 and the architects describe the structure aptly, even poetically, as: “A sequence of vaults along with a memory from the Pantheon, reemerged in a bronze-ochre tone. Double-bent glass encloses the diagonal slit that cuts through the building. Here the weather of the Öresund Strait, its fast-moving clouds chasing glimpses of sun, becomes present and tangible.” Last, but not least, on our striking cover this month is none other than Braytons Timbers, who supplied the timber structure to the Maputo Fishing Museum, which is featured in their cover story on page 10.

Braytons Timbers not only showcase their workmanship and quality supply, but delve into the details behind the project, including challenging logistics, and special timber treatment – all of which have fed into a remarkable and historic project that promises to stand the test of time. In other news, the SAISC announces the launch of their new digital design tool to aid structural engineers “to design the appropriate structural steel connection at the press of a button.” The tool will be publicly launched in April 2014. We are excited to announce our media partnership with both the Totally Concrete Expo 2014, as well as WoodEX for Africa 2014, to which we will be dedicating our May and June issues respectively, so you can look forward to great concrete and timber roofing in SA Roofing in the coming months. Please don’t hesitate to get in touch with us if you would like to participate in these highly targeted issues. Enjoy the read! Jen

STE E L

Steel construction digitisation tool ushers in new era in connection design The Southern African Institute of Steel Construction has developed a digital tool that enables the structural engineer to design the appropriate structural steel connection at the press of a button.

AISC education director, Spencer Erling, says that this programme will revolutionise the steel construction industry. “Imagine a digital tool on your laptop, tablet or smart phone, that is so intuitive you will be up and running in a minute, and within a few clicks the capacity of the connection is displayed,” Erling says. The entire process is as simple as it gets: 1. Click on the SAISC standard connection you want to use (there are 5 major groups, from which you can choose your particular requirement with sub groups e.g. major group, moment connections, sub group, with a haunch, etc.). 2. Select the member sizes you wish to join (a full database of sections is available to choose from). 3. Select the bolt diameters, number of rows of bolts and the plate thickness. 4. Push the calculate button and instantaneously the capacity of the connection is displayed. But there’s a lot more to this programme, says Erling. “By placing your cursor on the box you are told what the ‘weak link’ in the connection is, allowing you to refine the connection design. This is really a ‘jackpot’ feature of the programme,” he says. Once you know the ‘weak link’ the process is just as simple: 1. Enter all the loads from the analysis (axial, moment and shear) and a design check is performed. 2. Click to see a to-scale sketch of your connection with all stiffeners, dimensions and weld sizes specified, which you will be able to transfer to the construction drawings. 3. Click to open examples, discussions and commentaries relating to your design, so you can refresh your memory at an instant as to what was said in the SAISC Green Book about your particular design. 4. Save and/or print out summary of the connection design and file this in logical paper and/or electronic, traceable manner.

BACKGROUND TO THE CREATION OF THE DIGITAL DESIGN TOOL Connection design is a critical part of the structural steel construction process. The late Bernard (Tommy) Thompson of Dorman Long Africa famously said, “Steel structures do not fail because of inadequate member design; they fail because of inadequate connection design.” SANS10162:2005 sets down the rules for designing steel structures.

SAISC education director, Spencer Erling. To simplify the designer’s life, the SAISC publishes The South African Steel Construction Handbook, popularly known as the Red Book, which turns the code formulae into tables. This ‘Bible’ of the industry also provides guidance and general information to help the steel designer. In 2013, to complement updated versions of the Red Book, the SAISC published a new hard copy version of the Green Book, which brought connection design up to date. The book is notable for its guidance and includes a plethora of simplifications, where appropriate. “Once again, there is a great deal of text to explain ‘what and how,’ but also examples to guide the designer through the maze of formulae and methods,” says Erling. The book has become a desktop companion to those involved in connection design and more than 300 designers have attended the SAISC courses on connection design based on the Green Book. Notwithstanding the simplifications, connection design done by hand can be a laborious task, especially if the designer desires to optimise the efficiency (i.e. cost in Rands and Cents) of connections. “The net result is that too many steel structure designs are issued for construction with inadequate attention paid to the connections and their details. This is a serious concern for the SAISC and the industry and so, after a tremendous effort by the SAISC team, the new digital connection design tool was developed,” Erling says. “A tool of this type has been dreamt about for years and in April 2014 it will be publicly launched and the dream will become a reality,” Erling concluded.

LSFB

Survey reveals dramatic rise in use of light steel frame building method An industry survey by the Southern African Light Steel Frame Building Association (SASFA) has revealed a dramatic increase in the use of the light steel frame building (LSFB) method in South Africa.

Light steel frame building’s acceptance as a building method in South Africa is growing exponentially.

ASFA director, John Barnard, says that, in the main, the survey showed that the mass of steel used in South Africa to profile LSF sections increased by 6% during 2013, compared with the previous year. However, exports declined by 30%, largely due to the establishment of manufacturing capacities in the neighbouring countries, while the local market for LSFB grew by 21%, considerably more than the 7% growth recorded for the building industry (floor area of buildings completed) in South Africa.

A significant 24% of all buildings (residential and non-residential) completed, comprised of ‘Additions and Alterations.’

“As the volume of steel used purely for light steel roof structures remained fairly constant, all the growth came from steel used for complete LSF buildings, almost doubling the previous year’s figure for this sector!” Barnard says.

BUILDING INDUSTRY STATISTICS (STATISTICS SA)

The floor area of all buildings completed in South Africa during 2012/13, including additions and alterations, is reported to be 10 million m² – showing a growth of 7% compared with the performance of the previous year.

Industrial buildings and warehousing formed the major sector in the non-residential market, with 40% of the floor area, followed by office buildings (32%). The latter sector showed massive growth during the past year, more than doubling the floor area completed during the previous year.

New residential buildings (including alterations) made up 68% of the area of all buildings completed, and showed a 3% growth on the previous year. The largest sector in the residential market was Dwellings of more than 80m², followed by Flats and Townhouses.

“Based on building plans approved, we can look forward to a 16% growth in building activity during the next 12 to 18 months, keeping in mind that there is a lag of some nine months between plans approved and buildings completed,” says Barnard.

APRIL 2014

LIGHT STEEL FRAME BUILDING PERFORMANCE SASFA’s annual survey, which aims at quantifying the level of light steel frame building (LSFB) activity in the market, was again carried out during 2013. Barnard explained that, as in the past, SASFA approached the South African manufacturers of light steel framing to determine the volume of thin gauge high strength galvanized steel sheet they had processed during the past year, as a measure of the building activity in the industry. The manufacturers reported throughput of 24 200 tons of high strength galvanized steel sheet, reflecting 6% growth compared with production in the previous year. “Supply into the local market increased by an astounding 21%, while exports from South Africa into SubSaharan Africa declined by 30%. This decline can be ascribed to profiling capacity that is being installed in the neighbouring countries, as well as the increase in local demand,” Barnard says. During 2013, LSF roof trusses used with masonry or in industrial buildings constituted 54% of locally sold LSF. Roof structures covering a total floor area of 1.31 million m² was produced, on par with that during the previous year. “Based on Statssa figures for buildings completed in 2012/13 (excluding low-cost housing), light steel roof trusses captured 13% market share during the period, Barnard says. He adds that based on industry feedback, complete buildings – wall panels with roof structures – covering a total area in excess of 500 000m² were built in LSF in South Africa during 2012/13, which is an 80% increase on the 2012 performance. “This growth in demand is remarkable, as the official building statistics supplied by Statssa indicate a growth of only 7% in total floor area of new buildings completed during 2012/13. This underlines the rapidly growing acceptance of LSFB by architects, engineers, builders and clients,” Barnard says. But LSFB does not only consist of steel. Based on average ratios of wall area to floor area, LSF has in 2013 resulted in a demand for • 0.6 million m² of external cladding (typically fibre cement board) • 0.9 million m² of bulk insulation (typically glasswool) • 1.3 million m² of internal lining or gypsum board • 0.6 million m² of vapour permeable membrane used in external walls. Barnard says the total LSF market (local and export, trusses and complete buildings) is forecast to grow by 15% during 2014, compared with 2013. “The SASFA manufacturing members report good demand for middle- and upper-income housing, schools and classrooms, and roofing structures for low-cost housing projects – including a large affordable housing project in the Cape, which is being built using LSF,” Barnard says. He adds that LSFB is increasingly being used for external (and internal) walling of multistorey offices and commercial buildings, while a growing volume of additions to existing buildings is also reported. In addition, a number of project enquiries from neighbouring countries have been received. “The encouraging fact that the government recently announced that innovative building technologies, such as LSFB, will increasingly be preferred for new schools, clinics and student accommodation, will add additional growth potential,” says Barnard. “In view of all the above, the forecast 15% growth in the use of LSFB in 2014 may, in time, prove to be conservative,” he concluded.

Covering Africa one day at a time Braytons Timbers supplies prestigious Maputo Fishing Museum project

stablished in 1976, Braytons Timbers serves the local construction industry by supplying top quality prefabricated roof trusses and allied roofing materials. A family business headed by Bradley and Clayton Tiley, who, along with a highly skilled staff of designers and estimators in timber truss design, share more than 60 yearsâ&#x20AC;&#x2122; combined experience in the roof truss business, Braytons Timbers has extended its offering across borders by supplying the timber structure to the Maputo Fishing Museum project and erecting the structure as well.

MAPUTO PROJECT DETAILS: The Maputo Fishing Museum project was awarded to a contracting company named Texeira Duarte (www.teixeiraduarte.pt), an international construction company with offices in Maputo in Mozambique, who were commissioned by the fishing ministry in Mozambique to build the structure in the harbour at the Maputo port. The design was done by engineers in Maputo, and Braytons Timbers was commissioned to source all the material that was required to manufacture the curved laminated beams that were used for the trusses, as well as to assemble the trusses and all the components that were needed on the site. Braytons Timbers also supplied the timber uprights that carry the roof structure.

Braytons Timbers was one of only two companies that responded to the initial enquiry that was sent to a number of South African truss plants, and was very excited about the possibility of doing such a prestigious timber structure. The company promptly responded to this call, which impressed the client, who quickly made arrangements to meet with the team at their Johannesburg office. Once plans, planning, materials, time span and pricing were agreed upon, the project was set in motion.

GRADED AND TREATED TIMBER: The lead time for this project was a few months, because the timber that was specified by the engineers was all SA Pine Grade 7 and it had to be H3 (Hazard Class) treated. The timber sections were large, so they had to be procured from a timber mill that was able to supply the timber in the large dimensions to Grade 7 specifications, as well as be prepared to re-dry all the timber again once it had been treated to H3 (also specified, as the structure is exposed to the elements). Certificates for the grading and the treatment of the timber had to be secured from the mill, so that the client could be assured that they were getting the correctly treated timber, avoiding the fungus, rot, and insect infestation that can come with untreated or incorrectly treated timber, for a particular environment, over time.

SPECIAL STEEL FOR FIXINGS: All the steel components for this project had to be in stainless steel to avoid any rusting of the components, which will have to stand the test of time in the harbour, a highly corrosive environment. All the bolts, nuts, steel plates and connector brackets, etc. are of stainless steel and the task of collecting all these components in stainless steel proved time consuming.

RED TAPE: Braytons Timbers was issued with an import permit from the contractor in Mozambique that detailed all the timber that could be imported into the country. The department of agriculture in South Africa was issued a copy of the import permit, after which they had to inspect the timber on Braytons Timbersâ&#x20AC;&#x2122; premises and issue a certificate that stated that the timber complied with the requirements on the import permit before it could be sent over the border into Mozambique. Each load that was sent to the project had to be inspected and certified by the departmentâ&#x20AC;&#x2122;s inspector â&#x20AC;&#x201C; another lengthy process.

MANUFACTURE: A special laminating bed had to be made for the curved beams to be pressed in, so that the beams were made to the exact radius that was required for the design. Following this, a special jig had to be made up from steel for the truss components to be fastened together, as they were made in five sections (so that they could be transported). The jig ensured that once the trusses were all made, they were exactly the same, and once fastened together with the custom-made stainless steel plates, the trusses had a clear span of just under 40m. With a cantilever on either side, this takes the length of the trusses to 40m, with the only supports being on either end of the truss. Braytons Timbers had to rent an additional building to accommodate the 40m trusses, while assembling the parts for the Maputo Fishing Museum Project, as they had little space in their factory with all the other timber stock, as well as daily production operations.

APRIL 2014

COV E R STO RY ROOF SHEETING:

GRATITUDE:

Safintra Roofing in Durban had to send their mill to the site to roll the sheets on site, as the sheets were about 40m long. They had to get a temporary import permit to get the truck with the mill on it over the border and back again. These permits were issued incorrectly by the Mozambican authorities, resulting in the truck standing at the border for days before it was released into Mozambique and back to South Africa.

Braytons Timbers' management would like to offer a word of thanks to the following parties involved in the Maputo Fishing Museum Project:

COMMUNICATION:

To Braytons Timbers staff, who were so professional in dealing with this whole project; TDO Roofing for erecting the whole timber structure and for site supervision throughout the project; Kaiden Projects for fitting the sheeting on the project; and Safintra Durban for sending the mill to the site in Maputo and rolling the 40m roof sheeting on site.

Braytons Timbers had a challenge with the communication with the client, as all the drawings were issued in Portuguese (these drawings were translated into English by Tony De Oliviera of TDO Roofing, who was commissioned to erect the structure) and there was only one engineer that worked with Braytons Timbers from the construction company that could understand and speak English, so all communication was done through him. After all the challenges and frustrations for Braytons Timbers, the roof erector and the client, the construction company has impressed their client (the Fishing Ministry in Mozambique) to such an extent that they have approved phase 2 of this project and Braytons Timbers has been approached to manufacture, supply and erect this second phase. Talks are under way and the engineer has already met with Braytons Timbersâ&#x20AC;&#x2122; staff in Johannesburg to go through the drawings and to finalise all arrangements.

PAST PROJECTS & EXPERIENCE: Braytons Timbers has been involved with many roof structures, ranging from the simple gable-to-gable roof structures commonly used on schools in rural areas, to more complex roof structures, such as that of the 12 000m2 community health centres (mini hospitals) for the Department of Health, which have complex mechanical services, including theatre equipment, oxygen supply, general HVAC, and fire sprinklers, etc., which need to be specially accommodated by the timber trusses and structures surrounding and supporting them. The expertise and skill of Braytons Timbers’ staff has enabled the company to be involved with the design and manufacture of roof structures ranging from 50m2 to 13 000m2 . These structures include community halls, clinics, schools, welfare and pension offices, housing developments, magistrates courts, hospitals, prisons, police stations, churches and chapels, community health centres and various other buildings. Some of the projects with which Braytons Timbers has been involved include the Majuba Power Station near Volksrust, Kokstad Hospital, Newcastle Private Hospital (now a Mediclinic), Rheingold Centre in Newcastle, Bradlows Office & Stores in Ladysmith, the Old Magistrates Court in Pietermaritzburg, new residences at the University of KwaZulu-Natal in Pietermaritzburg, Ebotse Golf Estate in Rynfield, Benoni, Itshelejuba Hospital on the N2 near Pongola, private houses in prestigious developments, such as the Sakabula estates in Pietermaritzburg, Silverstream Estates in Silverlakes Pretoria, Southdowns Country Estate in Centurion, Waterkloof Lane Estate in Waterkloof Pretoria, the Stewards in Benoni, executive office blocks and houses in Silverwood Estate in Silverlakes Pretoria, the extensions for new rooms at the Zulu Nyala Safari Game Lodge in Hluhluwe, the Diamond Events Centre at the Zulu Nyala Country Manor in Fourways, Johannesburg, the Hunt Road Secondary School in Hunt Road, Berea, Durban to name just a few.

Braytons Timbers is proud to have the SATAS mark (Certificate number 056) on all its products, including the SANS 1900 on mono planer timber trusses. Braytons Timbers is audited by SATAS no fewer than seven times a year, so standards are kept at a consistently high level. Braytons Timbers’ plant has been developed to cater for the wide area the company serves, supplying trusses to the erectors who are fitting the trusses and coverings for us, which means that large orders can be supplied simultaneously and with ease.

WATE R PROO F I N G

Waterproofing and roofing in South Africa today Since South Africa's new democratic dispensation, stricter labour laws, more protection for consumers and far stricter reliance on compliance from a legislative point of view, as well as from a financial control and reporting stance, have forced the industry to revisit the way it does business. Industry insight from Paul Koning, President of the Waterproofing Federation Southern Africa (WFSA).

Image by Remzi Kuskan - https://www.flickr.com/photos/remzifotografie/6862297965/

THE IMAGE OF WATERPROOFING AND ROOFING, THE CHALLENGES IT FACES AND REASONS FOR THESE: The industry has evolved significantly over the years, with new waterproofing materials and systems continually being introduced. A great challenge in the industry is that few make the effort to address waterproofing as a very important element of building when it comes to design and implementation of specifications formulated by the right people. The various waterproofing associations and institutes have a range of expertise from experienced people in the industry who can offer the input of local and international manufacturers to assist in the compilation of the best specifications to suit the circumstances. This, of course, only covers one side of the industry – the new works market. Usually this market can be regarded as being reasonably stable and controlled to a degree by professionals who are responsible to their clients. A larger problem in the industry, however, is the ignorance of householders, property owners and building maintenance managers, etc., who have problems with roofs, whether flat or pitched, and do not know where to start to get them ‘fixed.’ Getting the names of contractors from the Yellow Pages or from the internet is not necessarily the best way. Many people get caught out because they are enticed by the blurb and false claims presented by unethical companies and enter into dubious contracts with them.

They subsequently pay the price. A ten-year guarantee given by a company that has no landline telephone, does not offer a physical address, and demands a huge up-front deposit, for example, should be warning enough. The local waterproofing associations and institutes try their best to steer consumers away from the ‘bakkie and brush brigade.’ Nobody wants a flat roof, because, it is said, they always leak. Why they leak is because not enough attention is paid to the detailing at design stage. The importance of the waterproofing element of a building, as well as the application of waterproofing are not understood. The approach of not investing enough in the waterproofing, because, for the most part, it cannot be seen, is common. However, the consequences of a badly designed flat roof can be horrific, and, not only costly to fix on a completed building, but very inconvenient and not always possible to completely repair. The right approach to waterproofing is just as important on domestic dwellings, but unfortunately is very rarely a reality and there are often no waterproofing details provided on the 1:100 drawings. A house is one of, if not the largest, investment the ‘man in the street’ will enter into in his life and he expects everything to be perfect. A leaking balcony or flat roof is anything but perfect.

The industry also faces both economic and legislative challenges on a daily basis, the Health and Safety and the Consumer Protection Act, to mention a couple. Because the industry is cyclical in nature, it is always difficult to get well-trained labour and to retain it. When there is no work, the labour force will move into a different industry that guarantees work for twelve months of the year. Still, over the last 20 years, the industry has proven resilient, despite the numerous challenges and the cyclical nature of the building industry, which goes hand in hand with economic uncertainties. Another serious problem is that waterproofing companies spring up all the time, but their knowledge and expertise are highly questionable. Consumers have to deal with these unscrupulous operators who give the industry a bad reputation. However, there are waterproofing and roofing industry umbrella bodies that are working hard to maintain a positive image, improve standards, quality and ethics in the industry. Success has been achieved over the years through the efforts of the Waterproofing Federation of Southern Africa (WFSA).

WHAT HAS BEEN ACHIEVED? 1. Waterproofing is now a recognised trade with the South African Qualifications Authority (SAQA) skills register. 2. CETA, unfortunately, has not provided the required learning material, although regularly requested to do so. However, a Western Cape company (HP Plum & Co.), at their own expense, wrote the training material for waterproofers and had it approved by CETA. This same company also set up a CETA-approved training school and offers training courses for waterproofers. 3. The SANS 10400 National Building Regulations (deemed to satisfy regulations) have been thoroughly revised. 4. Currently the SANS 10021, The Waterproofing of Buildings standard is being revised and updated. 5. In the Western Cape there are regular waterproofing workshops, often sponsored by major manufacturers and suppliers of waterproofing materials who realise the importance of training.

IS THERE ANYTHING THAT CAN BE DONE TO IMPROVE THE SITUATION? Skills development training has been widely regarded as critical, and many manufacturers and suppliers of the recognised waterproofing systems offer training programmes to waterproofing contractors. Some contractors have their own in-house training courses. Qualified training for waterproofers is available now, albeit currently only in the Western Cape. The waterproofing industry must work together to create a positive image, to continue to improve standards, quality and ethics in the industry. In the property market, the adage is “position, position, position,” whereas in waterproofing, it is “supervision, supervision, supervision.” Unfortunately, in many cases the problems are caused because the waterproofing job was not supervised properly by a competent and knowledgeable contracts manager on a daily basis.

With leaks in existing buildings, often the interpretation of the problem is totally incorrect, because the person inspecting the job is not experienced enough, has had no training, and has very little knowledge of construction. The developer, or the client, the contractor and specialist waterproofing contractor must all work together to achieve a properly waterproofed building. Price should never be the only deciding factor when it comes to waterproofing. Guarantees must also not be a deciding factor either. One always hears it said that waterproofing guarantees are not worth the paper they are written on. It is more the understanding of guarantees that is misunderstood and the credibility of the waterproofing contractor that is the problem. A guarantee only covers the workmanship that the system has been laid in accordance with the manufacturer’s instructions and to industry standards, with a warranty on the material against it being faulty; it is not that the building will not leak, and if the waterproofing is covered, it is up to the client to expose the waterproofing to prove bad workmanship or that the material is faulty.

CONCLUSION: In conclusion, to be more confident that you will have a waterproofed building, the following steps should be considered: Design and detail the waterproofing correctly at design stage, taking into account interfaces with other building elements. Only appoint an experienced and knowledgeable specialist waterproofing contractor who understands buildings and methods of construction. For re-waterproofing, such a company should be able to diagnose the causes of the problems correctly. The company must employ qualified waterproofers and also be financially sound and capable of handling the size of the job. The company should be a good standing member of one of the recognised waterproofing associations or institutes who are members of WFSA. A condition of the appointment must also be that there will be a qualified foreman on site all day and that the work will be supervised on a daily basis by a senior and experienced contracts manager/director of the company. The main contractor and sub-trades, such as bricklayers, plumbers, electricians, air-conditioning and irrigation contractors, etc. must be educated and understand the purposes of waterproofing and also, as important, the dampproof courses and damp-proof membranes, as the consequences for their disregard can be horrific. Consider carefully in the programme when the waterproofing should be laid to avoid having many trades working on top of the waterproofing causing undisclosed damage. Do not accept a quotation or tender on price and guarantees alone. Paul Koning President WFSA

Lifting Machinery and Lifting Tackle Safety in Construction By Neels Nortje, Health & Safety Manager, Master Builders Association KwaZulu-Natal

LIFTING MACHINERY

LIFTING TACKLE

Lifting machinery, such as tower cranes, mobile cranes, gantry cranes, teleporters and hoists must be designed and constructed in accordance with generally accepted technical standards. Lifting machinery and all its components must be thoroughly examined and subjected to a performance test, also known as a load test. This load test must be performed as prescribed by the standards to which the lifting machinery was manufactured. The load test must be carried out by a competent person that has been certified by the Engineering Council of South Africa as a Lifting Machine Inspector (LMI). The whole installation must be subjected to this performance test before it is put into use, every time it is dismantled and re-erected and thereafter at intervals not exceeding 12 months.

Just like lifting machinery, lifting tackle, such as chains, chain slings, ropes, straps, shackles and hooks must also be subjected to a load test. The load test must be done by a competent person. In addition to the load testing, all lifting tackle must be inspected by a competent person that has been appointed in writing at intervals not exceeding three months. The results of the load tests as well as the three-monthly inspections must be recorded in a register and such register must be kept up to date and on the site were the tackle is being used.

In addition to load testing, lifting machinery and all components that form an integral part of the lifting machinery must be examined by a competent Lifting Machine Inspector (LMI) every six months. The findings of the inspections, as well as the load test results, must be recorded in a register and this register must be kept on the site or premises where the machinery is used.

Now that we understand the difference between lifting machinery and lifting tackle and know at what interval they must be tested and inspected, letâ&#x20AC;&#x2122;s have a closer look at some of the lifting operations that are used in the construction industry. We will look at what dangers are involved with these operations, as well as illustrate what is required to achieve ultimate safety.

All lifting machinery must be clearly marked with the Maximum Mass Load (MML) which it is designed to carry safely. If the mass load varies with the conditions of use, then a table showing the maximum mass load for each position shall be posted where it is visible to the operator. Lifting machinery such as tower cranes must have a brake or device capable of holding the maximum mass load should the power supply fail to automatically prevent the uncontrolled downward movement of the load. It must also be fitted with suitable limiting devices to prevent overloading. Lifting machinery may only be operated by a person who is specifically trained for the particular type of lifting machine for which he or she has been appointed to operate. Operators of lifting machinery must receive annual medical tests and be declared fit to operate the type of machinery for which they are appointed to operate.

Lifting tackle could be identified and colour coded in accordance with the three-monthly inspections. This will make it easy for supervisors, operators and workers to see if the most currently inspected tackle is used on site.

TOWER CRANE Tower cranes are specialized machinery and form an integral and important part of many construction sites. A crane risk assessment must be conducted by an appointed competent person. Make sure that the crane is erected and used only as per the safe work procedures of the risk assessment. If not, the crane could be very dangerous and could even collapse. It is the responsibility of the appointed operator to conduct visual inspections of the tower craneâ&#x20AC;&#x2122;s structure whilst ascending and descending the craneâ&#x20AC;&#x2122;s access ladder. The operator must record the findings of these inspections in a register and keep it on the crane. If any visible defects are noticed, they must be reported to the site supervisor or manager immediately.

Tyre condition and pressure must be checked on a regular basis, while the all wheel nuts are fitted. Lights must be operational and it is important that headlights and taillights are in good condition. Inspect all grease nipples and all joints must be greased. There are to be no oil leaks. If any, report it to the supervisor immediately. Hydraulic pipes must be in good condition and attachments must be in working order with no leaks. Do not operate the mobile crane if you see any hydraulic leaks. Battery condition must be inspected: Batteries must be secured, terminals secured and no corrosion present. The boom must be in good condition with no visible damage. If this is not the case, degradation and defects must be reported. Cable and sheaves must be greased, and they are to have no visible damage or corrosion. Any defects must be reported. Brakes must be checked to be in good working order. By-pass valves must be fitted correctly, securely mounted, functional and no leaks must be present. A deflection chart must be fitted, in good condition and visible to the operator. Outriggers' condition must be inspected and foot plates must be fitted correctly when used for lifting. Do not use the mobile crane unless a risk assessment has been performed by a competent person on the outriggers and ground conditions on which the outriggers are going to be placed. Care must be taken of the crane’s electrical supply by making sure all the electrical cables are secured and that the DB is closed and protected and sign-posted with warning notices stating their presence. This will ensure good electrical safety when working with or around tower cranes. Bare wires or open, live DBs can be very dangerous. They can electrocute workers or be susceptible to rain and water damage, creating a very dangerous environment. Crane hooks must be pop marked and if the hook has opened beyond the safe limit, it must be replaced. All hooks must be fitted with safety latches and they must be functional. Make sure the MML is displayed and that the limit devices for both the mass and wind overloads are operational at all times. Make sure the condition of the crane’s access components have been checked. This will include the ladder, backrests and landing platforms. It is highly recommended that all crane access ladders be fitted with appropriate fall arrest systems. This will ensure ultimate safety for the operator. Make sure the cabin has been well constructed, is not damaged and is free from rust. Check the windscreen to make sure it is intact, ensuring that visibility from the cabin is never impaired. The hooter and siren must be in working order. Strobe lights or aviation lights are to be fitted to cranes that might be hazardous to aircraft.

MOBILE CRANE The fundamental advantage of a mobile crane is its ease of transportation and its flexibility in handling different types of loads or cargo quickly. This makes a mobile crane very useful and an ideal solution for work on a construction site. Here are the items one needs to check before using a mobile crane: Inspect the rear view mirrors, windscreen, windscreen wipers and indicators to make sure that they are fitted correctly, are in good condition and are operational. Hooters must also be checked, so as to ensure that they are in working order.

BANKS MAN A banks man is a skilled person who directs the operation of the crane and is in charge of the crane movements from the point of loading and unloading at ground level. The banks man directs the crane operator and controls all operations via hand signals. All signals made by the banks man or rigger must be noted and adhered to for safety and to ensure order is maintained on site.

GANTRY CRANE Gantry cranes are used to lift and move items around a working area. This makes them ideally suited for work in a factory, plant or machine shop. The gantry crane must always be in good working condition, load tested and inspected. The gantry crane’s logbook must be kept up to date and available in the yard where it is used. The operator must be trained and appointed in writing. Make sure the MML is clearly displayed on the crane, as well as the crawler beams. The operator must observe and adhere to the hand signals, given by the rigger or slinger, at all times. Where gantry cranes are in use, the area must be marked with warning notices. Signage such as ‘crane overhead’ must be strategically placed and in good condition as to ensure safety to those working in the area. Make sure the hooks are throat pop marked, with the safety latch fitted and functional. Make sure load limiting switches are fitted and fully operational. Finally, lifting machinery and lifting tackle must only be used as per the requirements of the Occupational Health and Safety Act and Regulations, as well as the manufacturers’ operating instructions.

Waterproofing Federation Southern Africa The Waterproofing Federation Southern Africa (WFSA) has been in existence for over 27 years, having been formed as a national body representing regional associations active in the waterproofing industry.

ounder members include Waterproofing and Roofing Association Cape (previously Waterproofing Association Cape), Waterproofing Association Gauteng (previously Waterproofing Association of South Africa – Transvaal), Waterproofing Association KwaZulu-Natal (previously Waterproofing Federation of South Africa – Natal). This grouping was later joined by the Waterproofing Association – Eastern Cape. Unfortunately, due to the lack of any driving force, the Waterproofing Association KwaZulu-Natal and the Waterproofing Association Eastern Cape are no longer active. WFSA is trying very hard to re-establish associations in these regions. The current members of the National Body, WFSA, are The Waterproofing Association Gauteng (WAG) the Waterproofing and Roofing Association Cape (WARAC) the Professional Waterproofing Association (PWA) and the Roofing and Waterproofing Institute (RAWI).

THE AIMS AND OBJECTIVES OF WFSA ARE: 1. To promote, to support, to protect and to further the common interests of Clients, Specifying Authorities, Manufacturers, Contractors and Suppliers of waterproofing materials and methods of installation. 2. To represent Members in their individual and collective capacities. 3. To represent the interests of all Members in collaboration with other affiliated Trade Organizations, e.g. concerning wage rates or conditions governing employment of operatives engaged in the Industry as outlined under ‘1’ above. 4. To represent the interests of Members in relation to Conditions of Contract with Government Departments, Local Authorities, Professional Societies and the like in order to obtain fair and equitable treatment. 5. To confer with and, as thought fit, to collaborate with any Association or Federation of Associations or any other body having the interests of Sub-contractors in the Building Trade as their objective, and/or to enter Membership of such Associations or Federations. 6. To regulate and to maintain the highest standards of workmanship and materials and to encourage, assist and extend the spreading of knowledge and information concerning the Waterproofing Industry. 7. To establish standards of good application and product specifications for the Waterproofing Industry in Southern Africa. 8. To co-ordinate efforts between all Members of the Waterproofing Industry.

Through its member associations and institutes, membership includes waterproofing and roofing contractors, and all the major manufacturers and suppliers of waterproofing and roofing materials in South Africa and independent specialized waterproofing consultants. In addition, affiliate members represent Institutes of Architects, Training Colleges and Universities. WFSA, being the official spokesperson for the waterproofing industry, sat on the Standards Generating Board (SGB) for the Construction Education Training Authority (CETA) and established waterproofing as a registered trade, having a Skills Register through the South African Qualifications Authority (SAQA). CETA was not active in writing the required learning material for waterproofers; however, a Western Cape roofing company, HP Plum & Co. took it on themselves to write CETA-approved learning material and established a training facility – currently the only facility in South Africa offering a CETA-approved waterproofer training course. WFSA is also represented on the South African Bureau of Standards (SABS) committee for waterproofing and, driven by Paul Koning, WFSA’s President, has written and proposed amendments to the SANS 10400-L: The National Building Regulations - Part L: Roofs waterproofing section. Currently the SANS 10021: The Waterproofing of Buildings Standard is being revised. It is strongly recommended that when appointing a specialist waterproofing contractor, the company should be a member of an official association or institute, either WAG, WARAC, PWA or RAWI. The WFSA website, www.waterproofingfederation.co.za is currently being addressed and will contain links to the member associations. Visitors to the website are able to access information about the members, their codes of practice, forthcoming events, and other interesting information relating to waterproofing.

In his recent State of the Nation Address, president Jacob Zuma said, “In 2012 we unveiled the National Infrastructure Plan, led by the President through the Presidential Infrastructure Coordinating Commission. We have subsequently invested one trillion rand in public infrastructure over the past five years. Many of the projects are completed or are nearing completion.” He declined to present the programme of action for the current financial year, stating “that programme will be presented by the new government after the elections.” “While the construction industry is grateful for the contribution the government has made, it is disappointed that there are no plans, as yet, for it to continue in this vein,” says Rob Johnson, Executive Director of the Master Builders Association of the Western Cape (MBAWC), a registered trade association for employers in the building industry. He continues, “The industry is still recovering from the effects of the global recession and needs to have some measure of reassurance that the government, regardless of whether it remains in the hands of the ANC or is taken over by another party, will continue to support it. Government is in the best position to deliver a consistent workload to the construction sector and thereby reduce the effects of economic cycles. Our industry has the capacity to absorb large numbers of unemployed people, and thus enable the development of skills, if a steady workflow can come from government.”

“In terms of training and skills development, we commend the government’s achievements, particularly the increase in the number of enrolments at tertiary level, the much-improved matric pass rate and interventions aimed at bettering maths and science. We also applaud their efforts to make further education more accessible both through the National Student Financial Aid Scheme and the construction of additional FET Colleges,” says Johnson. “We will continue to support government’s efforts through our artisan, skills and bursary programmes. However, these can never be on the scale required to service the industry as a whole,” adds the Executive Director. “It is our hope that the party elected on the 7th of May 2014 will continue to build on the foundations laid by the current government,” concludes Johnson.

he main idea of our winning competition entry was to hide inward-looking retail behind a wreath of residential and commercial buildings. The whole shopping complex would thereby eventually become integrated into the fabric of the city. It is a huge development, of which only the corner building with the Amber Entrance has yet been completed. Looking from Hyllie Station Square, this entrance will be the only part of the Emporia shopping centre that remains visible when the

development is completely built out. The idea of lining the streets with mixed-use buildings demanded a strong form that could attract visitors from Station Square to come in and shop. A sequence of vaults from a previous competition proposal, along with a memory from the Pantheon, reemerged in a bronze-ochre tone. Double-bent glass encloses the diagonal slit that cuts through the building. Here the weather of the ร resund Strait, its fast-moving clouds chasing glimpses of sun, becomes present and tangible.

APRIL 2014

A RC H ITE CTU R E Image by: Tord-Rikard Söderström The diagonal entrance from Hyllie Station Square leads deep into the block. Inside, retail is organized around a three-storey figure eight. Shops are grouped together around boldly coloured atria, each with a different theme. On the north side of the complex, a ramp leads into a rainbow-coloured parking garage (for 2500 cars) with direct access to the figure eight. To the east is a surface parking lot (for 500 cars) right outside the supermarket. The rooftop park is designed as a bit of cultivated nature. Its vegetation (sedum, prairie grass, and trees) and its sun-facing, wind-sheltered patios are accessible from both inside and outside the building. The hills that provide protection from the wind are actually hiding mechanical rooms. In the future the roof will be developed with outdoor dining and a spa facility – like amusement parks, shopping centres need to offer new attractions at regular intervals. Emporia can expand upward and to the west, but not in any of the other directions. The freestanding residential buildings facing Boulevarden have yet to be built, as are those that will stand atop the podium along Stationsgatan on the south side. Emporia’s interior challenges established shopping centre conventions.

Its bold colours and bent sightlines break with the norm, as do the project’s size and ambition – which have made it possible to do custom designs for everything from ceilings, floors, and storefronts to signage, ropes of hanging plants, furniture, and cast glass door handles. Our motto has been “no intermediate scale” – because that is the realm of the products on display. Large-scale patterns and intricate details characterize the interior. The terrazzo floor is typical of this approach, with its oversized triangular joint pattern, its gradual shift from white to graphite in seven steps, and its flashing inclusions of coloured mirror glass. The design has been wrought with extraordinary attention to detail, down to the leather-wrapped handrails and the colour of the stitching on the built-in seating. Emporia also includes a quantity of art seldom seen in a commercial environment. A lighting installation (ninety-nine bollards) by Petteri Nisunen and Tommi Grönlund lifts the Amber Entrance, bronze sculptures by Joep van Lieshout and a glass art piece (4 x 81m) by Silja Rantanen adorn the Sea Entrance, and a line painting on film at an extremely outsized format (20 x 114m) by Per Mårtensson clads the façade of the parking garage.

ABOUT WINGÅRDHS Wingårdhs is the common name for Wingårdh Arkitektkontor AB and Wingårdh och Medarbetare AB. Gert Wingårdh, architect SAR/MSA and CEO, is the owner and manager. Today, the firm is among the five largest architect groups in Sweden, and among the ten largest in the Nordic Region. This falls well in line with the target set in the office’s general objectives that we must be one of Scandinavia’s leading architecture firms. Wingårdh Arkitektkontor AB has been operating in Gothenburg since 1977, in Stockholm since 1985, and in Malmö since 2011. As we enter our 35th year of business, we employ 93 men and 77 women in our total of 170 staff.

The firm has an expressed objective of recruiting personnel primarily from the younger generation. This gives everyone a chance to assume responsibility and to develop within a range of projects. We have established a very sound organizational structure and the company works on all types of projects, from product development (e.g. Volvo’s stands at international auto shows) and interior design to large structures (e.g. Hyllie centre in Malmö) and urban planning projects (e.g. Havneholmen in Copenhagen). We work on projects in all phases, from pilot studies and surveys, to completed construction documents, and have extensive experience working with both renovations and new construction.

Totally Concrete introduces new building and construction technology to Africa Not only does 2014 mark a time of growth for Africa, but also a time of distinct development for the cement, concrete and construction industries.

rowth markets are anticipated across sub-Saharan Africa, spurring rapid infrastructure development and the construction business opportunities that come with it. With myriad building and construction projects under way, the prospect of high returns from project tenders is bringing thousands of industry stakeholders to the Totally Concrete Expo. The delivery of timely and sustainable infrastructure in Africa requires effective industry collaboration, both domestically and across borders, next generation building technology, and innovative materials. Historically, it has been a very real challenge to complete construction projects on budget and on time in Africa and the injection of new practices and technologies is vital to fast-track development. Many of the latest innovations in engineering and building technologies are arriving in Africa for the first time at Totally Concrete, taking place from 26 to 28 May in Johannesburg, South Africa. Industry growth estimates have sky-rocketed and it is now estimated that US $940 million will be invested into the cement industries of South Africa, Zambia, and Zimbabwe alone by 2018. New cement plants are also being built in a number of other African countries. Happy-Girl Buthelezi, Head of Business Development at PPC South Africa will outline how PPC is helping build Africa to the apex of its economic potential through its cement plant construction projects in the subSaharan region and Eng. Wolfram Schmidt from the BAM Federal Institute for Materials Research and Testing in Germany will share findings from the first ever Africa-wide cement competency testing programme.

Totally Concrete provides a crystal clear picture of where the industry is headed, recognising that next generation tools and technology are required to enhance the local and regional built environment. Clem Sunter, Chair of the Anglo American Chairmanâ&#x20AC;&#x2122;s Fund and renowned conversational model strategist, will deliver the keynote address and Daniel Silke, leading political analyst and futurist, will give a presentation that sets the stage for shaping the future of Africa and defining the role that the construction industry will play therein. Incorporating both strategic and technical elements, Totally Concrete has practical tools and techniques for all professionals active in the construction sector. Stakeholders from over 40 countries worldwide will have an opportunity to access cutting edge technology as it arrives for the first time on African soil. Totally Concrete is endorsed by over 60 industry associations and sponsored by PPC, Lafarge, AfriSam, CCS, PMSA and Nyeleti Consulting. Martin S. Owuor, First Secretary of the High Commission of Kenya, says of the event, â&#x20AC;&#x153;Totally Concrete is very informative and very important at this critical time when Africa is trying to improve infrastructure necessary for development.â&#x20AC;? Totally Concrete is the only all things cement, concrete and construction event in Africa that provides the entire industry ecosystem with the tools and solutions needed to manage projects of all sizes and ensure their delivery on time and on budget.

Kahn & Kahn provides a

package deal to local industries Industrial packaging and construction sheeting expert, Kahn & Kahn Plastics, has successfully achieved consistent and measurable growth over the decades, having developed a long-standing reputation for its specialised product offering.

ohannesburg-based Kahn & Kahn forms part of the Damax Plastics & Packaging Group, and managing director, David Tromp, notes that the company specialises in the manufacture and supply of industrial grade plastic products. "Our industrial plastic packaging capabilities are comprehensive, and range from bubble wrap and cable ties, to refuse bags, masking tape and seals." For the construction industry, Tromp indicates that Kahn & Kahn specialises in plastic sheeting for foundations, walls and roofing. "To complement this flagship range, we also offer the local construction industry value-added support products, such as, but not limited to damp proofing, joining tapes, refuse bags, stretch/pallet wrap, orange barrier netting, Polypropylene bags, shrink sheeting, carrier bags plain/printed, bubble wrap, tapes, plant bags, tubing, Sisalation insulation and painter's sheets," he explains.

To maintain a leading edge in the industry, one of our main priorities moving forward will be the reduction of our overall carbon footprint through the implementation of new recycling initiatives." Looking at the local plastics and packaging industry in general, Tromp remarks that growth looks set to continue. “The plastics and packaging sector is a fast growing industry that is able to offer great value to a number of other industries. Kahn & Kahn aims to expand and be a part of this increasing growth. Our core focus for growth in 2014 is through sales, and we are introducing advanced new systems to ensure that our sales team remain leaders in their field,” he concludes.

From humble beginnings in 1980, Kahn & Kahn today boasts a team of 40 staff members. Tromp attributes this success to the 1999 acquisition of Kahn & Kahn by the Damax Group. "By combining its capabilities with ours under one roof, the Damax Group has enabled us to reach into new avenues of growth that were previously unattainable as a small standalone company. According to Tromp, Kahn & Kahn has grown into a successful and well-respected business, despite a number of challenges in the local market. “As a result of economic pressures, the construction industry in particular has seen a sharp decline, which has had a direct impact on our business. This presents a major challenge. However, Kahn & Kahn has been able to weather the storm and has maintained a steady growth in profits despite these challenges." The continued influx of cheap and inferior imports from Asia is another major challenge locally, adds Tromp. "Although these products entice end users through an initial purchase cost saving, the long-term implications related to product defects and failure can prove to be immensely costly. Kahn & Kahn prides itself on its reputation for quality, and has always risen above the trend of sacrificing quality in order to cut costs,” he continues. Tromp reveals that 2013 was a good year for Kahn & Kahn, with the company experiencing growth in profits, when compared to 2012. "The future outlook for the company is positive. Kahn & Kahn boasts a dynamic and hard-working team, which has resulted in continued success year after year.

Saint-Gobain Gyproc celebrates 85 years in SA This year, leading interior building solutions group, Gyproc, a division of Saint-Gobain, celebrates 85 years of successful trade in South Africa.

oyal customers and key stakeholders joined the senior executives of the company for a gala dinner, to commemorate and celebrate the company’s milestone, held at Monte Casino. The company, which designs, manufactures, and distributes building materials, began local production in 1929 with the establishment of Rhino products, to manufacture plasterboard by hand. Branded then as Rhinoboard, this innovative product still provides versatile, distinctive aesthetics to enhance the interior styling of any building, from hospitals and schools to homes and leisure centres. Gypsum Products was registered as a company in 1930, with the American company Gyproc becoming a 51% shareholder in 1946. The early fifties saw great increases in the demand for Rhinoboard due to the increased demand for houses needed by returning soldiers. Sales increased into Africa, including in Kenya, Malawi and Tanzania. In the latter half of the 1950s when there was a downturn in the building industry, the company known then as GIL (Gypsum Industries Ltd.) diversified into mining, only returning to the manufacture of Rhinoboard and Plaster in 1964. A concerted effort was made by the company to get Rhinoboard specified as a requirement in all government work and in educating architects about the use of gypsum. When there was economic turmoil again in the 1970s, the company expanded its product range to penetrate the walling market by introducing several new products and building systems. A new company, Donn Products, was set up, later to become part of United State Gypsum, which held the license to manufacture Donn’s ceiling and wall grid components locally. The 1980s saw a boom in the housing market as a result of the government needing to provide housing for an increasing population. The 1990s saw further expansion with the company realising that all production needed to be concentrated in Brakpan, the location of a modern plant which was built in 1991, which, due to its homogenizer structure and single span roof, had won an award for its design. GIL was delisted from the JSE in 1996 with the company being renamed BPB Gypsum, a move which enabled the South African operation to achieve international status. The new millennium saw further changes with Donn and BPB sales depots being merged into one entity, called LBS (Lightweight Building Solutions), now Gyproc Service Centers. In December 2005, the French multinational corporation, Saint-Gobain purchased BPB Gypsum. The local team chose the company name Gyproc because it emphasised the use of gypsum elements used in the company’s products.

Regional Managing Director of Saint-Gobain, Steve du Toit,. Saint-Gobain Gyproc has since then grown from strength to strength with over 12 new innovative products being introduced to the market over the last two years. 2014, the company’s 85th year in South Africa, will be another exciting year with more innovative solutions being introduced to the market to enhance energy efficiency and environmental protection. In delivering his address at the gala evening, Regional Managing Director of Saint-Gobain, Steve du Toit, emphasised the point that as a company, Gyproc, whilst celebrating 85 years, is continually evolving as a business. “The business launched 18 new products in the past 18 months and has 10 more innovative product launches planned for this year. In the coming five years, we plan to launch more new products than the business has introduced in the past 85,” announced du Toit. “Our core focus will be on our customers, their experience in dealing with us, and how best we can service their needs. In addition, we are looking beyond our immediate borders with expansion plans into Africa, so there are many more exciting years ahead,” he said. He ended off by thanking their loyal customers for their support over the past 85 years, making reference to the point that without customers the business would not exist at all. Guests who attended the gala dinner celebration were entertained by Swing City and the Mzanzi Youth Choir and South African actress and sports personality, Vanessa Hayward, was the host for the evening.

Announcing Sika RainTite

Now in 1ℓ size

Sika RainTite 1ℓ has recently been launched into the DIY waterproofing market, offering an add-on to the waterproofing basket. The 1ℓ is now available for DIY users with a very small area to treat or who simply need a small amount for a minor job.

ika RainTite 1ℓ is used in conjunction with a Sika RainTite membrane to form a durable and flexible waterproofing system. It can be used to waterproof flashings, parapet walls and sealing joints, laps and roofing screws on corrugated roofs. Other characteristics include UV resistance, easy application, very economical, vapour permeability and excellent adhesion. It is simply brush or roller applied in a generous amount to a clean, sound surface. While still wet, the membrane is embedded in the base coat, air pockets and creases smoothed out with overlaps of adjacent membrane overlapping by a minimum of 50mm. A second coat is applied immediately, while the base coat is still wet, in order to fully saturate the membrane on both sides. When touch-dry, the final top coat can be applied and the system must be protected from rain until it is dry. Sika RainTite 1ℓ is now available in 9 colours: Charcoal, grey, green, terracotta, red, white, brown and now also burgundy and black.

RAINTITE KIT 5ℓ NOW IN BLACK AND BURGUNDY Due to customer demand, Sika has recently expanded the RainTite kit range by introducing two new colours: burgundy and black. By adding these new shades, the range now offers the end-user a kaleidoscope of colours to match their roof colour. The RainTite kit 5ℓ is combined with a free 10m x 200mm roll of membrane, making waterproofing simple and efficient for the DIY end-user to fix jobs around the home. Sika RainTite is available in 5 litre kits in nine different colours: charcoal, grey, terracotta, brown, white, red, green, burgundy and black.

SA’s doyen of waterproofing engaged to boost a.b.e. product promotion The extensive experience of Gordon Anderson, one of South Africa’s foremost authorities on waterproofing, has been engaged on a consultancy basis by a.b.e. Construction Chemicals. a.b.e, part of the Chryso Southern Africa Group, has, for close to 75 years, been manufacturing products that have become synonymous with waterproofing in South Africa. Over the years, the company’s wide range of waterproofing products have provided maximum protection to multi-million rand projects such as uShaka Marine World, various soccer stadia for the FIFA 2010 Soccer World Cup, Gautrain, and Vodaworld’s Vodacom Data Park, to name just a few. Furthermore, it has been estimated that a.b.e. has already supplied products to waterproof close to 800 000 houses in southern Africa.

“My task for a.b.e. is to convince professionals and applicators to spend more time and money on waterproofing,” he adds.

Gordon Anderson’s reputation in the field of waterproofing – as well as his array of industry contacts – is equally impressive. He started his career in waterproofing when he joined the Gundle Group in 1979 and subsequently became MD of Gundle Coatings, the Group’s waterproofing division, which later became Barrier Coatings. In the early ‘90s, he joined the Derbigum Group as consultant and later became a member of the board of directors. He resigned from Derbigum in 2006 to pursue a career as private consultant and his waterproofing skills and experience have now been retained by a.b.e. A man who says he is “passionate about waterproofing,” Anderson says a.b.e. products are already present on virtually every building site in the country, but he sees tremendous potential for developing the brand even further in future. “My role will be to promote a.b.e.’s waterproofing range to the professionals and applicators whose trust and confidence I have acquired over my 35 years in waterproofing. I not only want to introduce the range to new specifiers and users, but also to revive interest among stagnant customers,” he explains. It is a challenging assignment, as Anderson believes there is still tremendous ignorance and apathy about the importance of waterproofing among architects and designers. “The budget for waterproofing in this country has been estimated to be less than 0.5% of the total cost of a new structure. This apathy – which is a global problem – inevitably boosts the number of waterproofing failures. A recent study in the U.S.A., for example, showed that 59% of the call-outs contractors had to contend with in the first year of completing a project were caused by waterproofing defects.

The Government’s new Health & Safety Construction Regulations 2014 were officially promulgated on February 10 along with the certification that SA Council for Project and Construction Management Professionals (SACPCMP) is the appointed registration body for Construction Health and Safety practitioners.

aster Builders Association North will be running a series of workshops for contractors this year, highlighting – and simplifying – what these regulations mean to the contractor. The Department of Labour (DoL) has offered its assistance, so, where practical, the workshops will be run in collaboration with representatives from the DoL. “Where the previous regulations failed in adequately identifying responsibilities from client through to contractor, the Construction Regulations 2014 endeavour to redress the situation which saw continued frustrations with generic health and safety specifications often issued after project start dates,” says Doug Michell, MBA North Construction Health & Safety Manager.

• Application for construction permits – clients’ responsibility • Clients’ duties and responsibilities • Designers’ duties and responsibilities • Principal contractor and contractors’ duties and responsibilities • Managers’ duties and responsibilities • Registration of CHS practitioners • Operational regulations 2003 vs. 2014 The workshops will be run in all four provinces of the MBA North: Gauteng, Limpopo, North West Province and Mpumalanga.

MBA North to present workshops on new construction regulations

Adds Mohau Mphomela, Executive Director of MBA North, “The workshops we are going to stage will simplify the Construction Regulations to assist our members to more fully understand the implications thereof – and how these will affect/impact them and their businesses.” “Our contractors/members are constantly busy on construction sites. Instead of them having the arduous task of studying and interpreting a myriad of pages explaining the complex legislation, MBA North intends to summarise and simplify it for them at the workshops,” Mphomela added. The dates of the MBA North workshops still have to be announced, but will cover changes to the regulations (2003 vs. 2014) with particular focus on:

SAPMA considering special training for rural retailers The SA Paint Manufacturing Association (SAPMA) is investigating the feasibility of formulating and presenting special tailor-made training courses for the retail sector.

Where there’s a windmill in the countryside, chances are there’s a hardware store nearby – even in small villages. SAPMA now wants to bring paint training to the men and women on whose advice country folk depend.

eryck Spence, SAPMA executive director, says initial discussions with SAPMA members in the retail sector have proved extremely positive. “It’s still early days, but what we envisage is meeting with a SAPMA retail group, finding out what their sales personnel particularly need training in, and then developing a special course – especially formulated for this particular retailer’s needs.” “SAPMA’s training arm, the SA Paint Industry Training Institute, SAPITI, would establish the retailers’ preferred location and could even take the special five-day course – which could be broken up into daily segments if required – ‘on the road,’ so to speak, visiting relatively obscure rural areas where the hardware retailers have branches and providing training for their sales staff there. The Chemical Industry Education and Training Authority (CHIETA) would welcome SAPITI taking training into the countryside as one of its major aims is to provide training for rural communities,” Spence added.

“All members of the paint and coatings supply chain – including retailers and applicators – could face prosecution for breaches of the Consumer Protection Act. If untrained sales staff, for example, provides wrong advice to a consumer who then incurs losses to property, the retailer would land into serious trouble. Applicators also need trained staff and have, for years, had to provide in-house training to carry out their operations,” Linossi states. The standard five-day SAPITI Retailer Paint Course curriculum covers, for example, the functions and ingredients of paint, choosing the correct product, dealing with lead-based paints, project planning and preparation, painting of new and previously painted surfaces, health, safety, the environment, paint failures, and problem solving, as well as legislation. For more information about the scheduled dates of these courses, contact Tina Taylor at SAPMA on 011 455 2503 or training@sapma.org.za.

Mandy Linossi, SAPMA Training Administrator, says hardware retailers now, more than ever before, need fully-trained staff.
