Just over two weeks in motion as I write this, the strike was meant to be on a firm path to resolution by now. But this does not yet seem within reach.

In the meantime, some of our clients’ premises are under lockdown, some can’t access the general area of their factories for fear of their safety, some employees who are not interested in striking are either intimidated into doing so, or must resort to changing their lifestyles in the interim so as to avoid the repercussions, security measures are on the up and up, and the knock-on effects of the strike seem to be stretching far and very, very wide.

But discord, disenchantment and accountability all have a place on both sides of what is becoming, if it isn’t already, an economy-crippling syndrome. To quote Gerhard Papenfus, CEO of the National Employers’ Association of South Africa (Neasa), from an Engineering News article titled ‘Metals industry a ‘liability’ for South Africa – Neasa,’ “Employers bowing to the unlawful violence and intimidation are creating a bleak future for themselves. The repeated surrendering to unlawful action has created a metal industry in self-destruction mode, an industry on a downward slope…We are now paying dearly for those cosy deals between weak employer representatives, big

business and big trade unions, over decades, which has brought a once-mighty industry to the brink of destruction.”

This destruction we cannot afford.

To round off an issue that, for us, is also impacted by the metalworkers’ strike, and whose backdrop is that of an industry under severe threat, we offer some labour insight on the current strike from Advocate Ilene Power, a leading practitioner in employment law who also consults on workplace relations, conflict management, dispute resolution, litigation and facilitation.

A calm sea never made a skilled sailor, they say. We wish you all the best in weathering this storm.

Enjoy the read. Jen

Striking a chord It seems like a stretch of the imagination to think that the publishing industry

could be impacted by the current metalworkers’ strike. And yet, in our shoes, with metals being an intrinsic component of the roofing industry, the

connection needs no introduction. We are also feeling the effects.

History will remember the past few years of the South African labour environment for the Marikana incident, the subsequent

Platinum strike, which has just ended, and the current Numsa national strike demanding a 15% pay increase, together with the banning of labour brokers.

It is common cause that there are dire consequences to the labour movement’s destructive and violent downtime. The unions proudly exert their power, leaving a trail of damage in their wake that we can’t really quantify and it seems that there is no recourse. Consequently, the South African economy is the biggest loser. Our economy, arguably the biggest in Africa, and a top emerging market, is being held ransom by South Africa’s unionised labour force.

South Africa is one of the BRICS group of emerging economies considered to have big potential, which includes Brazil, Russia, India, China and South Africa. However, the South African economy is not keeping up with the rest of sub-Saharan Africa, one of the world’s fastest-growing regions. This is because South Africa faces a unique set of domestic problems that have less to do with global trends and more to do with the country’s unique socio-economic background. A significant portion of our socio-economic background belongs to the complex variables that dictate South Africa’s unionised labour force. Hidden agendas and politicised motives influence and instil a system where the tendency is not to constructively engage for the betterment of the workers, but is rather aimed at fermenting discontent. The catalyst for this destructive approach is found in the all-purpose justification that the South African labourer needs to be freed from the bounds of economic oppression, despite the dire consequences, least of all the strikers being worse off than when they started, in the greater scheme of things.

I am reminded of the influential leader of the Mine Workers union in Britain, Arthur Scargill, and his interesting philosophy called impossibilism: “The essence of impossibilism is to set workers off after a set of demands which are impossible to achieve. Which is not as daft as it looks. It educates workers in the grim truth that the current system cannot – of its very nature – meet their demands. That lifts the struggle onto a higher and more revolutionary plain, especially if the ‘repressive brutality’ of the State, as well as the realities of capitalism, are employed in breaking the strike.”

Therefore, if strikers are set up to fail and to lose their jobs, they can then be easily persuaded to reject the whole capitalist system and to fight for its complete overthrow (revolution). This philosophy is clearly evident in our time when we consider the conduct of unions such as AMCU (whose number one supporter is none other than Julius Malema and his EFF) and Numsa. These militant unions are lifting the ‘struggle’ onto a higher plain than the best interest of the worker and into a more revolutionary plain – to achieve particular agendas and goals.

A look behind the scenes of the current metals and engineering strike reveals a picture of a complex negotiating process filled with the complex variables of internal strife, poor leadership, conflicting interests and unethical behaviour. One example was recently highlighted by Mr Gideon Du Plessis, General Secretary of Solidarity. According to du Plessis, Numsa is abusing the pressure brought about by the strike to secure its own interest.

A recent dispute about Numsa’s membership figures for the specific industry has resulted in the suspension of the current bargaining fee agreement. Numsa’s membership ranges between figures of 220 000 (which it is now presenting to the media), 130 000 (according to the bargaining council’s records) and 70 000 (according to two independent audits undertaken by KPMG and the Department of Labour, respectively).

In the past, Numsa seemingly unlawfully derived a benefit of R6 million per month as a result of a bargaining fee agreement in which they over-inflated their membership figures. According to du Plessis, Numsa is using this strike to attempt to bully the Minister of Labour to extend the agreement and advance its own interest to restore its golden financial thread through the back door and in so doing, sidestep corporate governance processes.

Furthermore, the employer organisations are negotiating with Numsa in a highly tense atmosphere, despite the fact that Seifsa (the Steel and Engineering Industries Federation of Southern Africa) has already complied with Numsa’s demand for a double figure increase for year one. One would think the parties could therefore call it a day, shake hands and move along. However, according to du Plessis, Numsa cannot settle that soon, because its leaders need ‘airtime’ to make populist statements in pursuance of the example of AMCU leader, Joseph Matunjwa, by addressing the cheering workers’ class who believe the strike is about their interests.

Furthermore, at the start of the strike, the Numsa leaders indicated that the trade union would lower a 15% demand to 12%, but would consider a 10% increase. In divergence, Numsa’s Gauteng structures acted in bad faith by unilaterally reverting to a 15% demand, an approach that supports my position that the unscrupulous agendas of union leaders drive the action, rather than the best interest of the workers.

Another substantial portion of our socio-economic background is the violence and intimidation that mars our South African way of protest. Back in the ‘80s, with unions being at the forefront of the struggle against the Nationalist (apartheid) government, a time of strikes, mass action and, of course, the armed struggle in South Africa, there was a concerted philosophy that called for a revolution and therefore made sense at that time. This same philosophy is now playing out through revolutionary workers that stoke the conflict and wreak havoc at the workplace through destruction, and assault, sometimes even killing those who do not support them.

The numerous incidents of violence and intimidation experienced in our strikes indicate to me that the struggle is still alive and kicking with the same philosophy that the wrongdoing can be justified by pointing to a good outcome.

Is this economic freedom ideal the noble goal that justifies workplace anarchy? Do the ends justify the means? Are these protracted strikes really the most effective way of resolving labour disputes? Should Government allow these militant trade unionists/revolutionaries to achieve their goals through any means necessary, no matter how illegal or unpleasant the means may be, or is it time for the impunity to end?

Whilst the constitutional right to strike should be respected, society also has a right to protection and the enjoyment of free economic participation, and therefore a balance must be struck between workers’ rights and the rule of law. I believe there are ways to achieve this.

Trade unions in the UK concluded years ago that there were far more cost-effective and efficient ways of resolving disputes, and also found that more innovative approaches actually contributed positively to job creation. The Engineering Electricians, Telecommunications and Plumbing Union began to doubt the strike as the most appropriate method of resolving labour disputes and began looking for alternatives. What emerged were agreements with a number of companies that provided that wage (interest) disputes would be resolved by ‘pendulum arbitration,’ rather than strike action. Where a dispute is referred to pendulum (or final offer) arbitration, the arbitrator is required to choose between the final offers submitted by each party, as this encourages both parties to submit realistic final offers and demands, and justify them with appropriate information. Many proponents believe that by agreeing to submit interest disputes to pendulum arbitration, a more sustainable and mutually beneficial dispensation emerges that contributes to job creation, foreign investment, improved wages and fewer retrenchments.

The time is right to call for better alternatives as we need a solution that is acceptable to both parties. Therefore, the call on Government to draft law, seeking to introduce legislation that would force undisciplined unions to take practical steps to prevent strike-related violence is a positive step in the right direction.

The DA’s proposal to empower our courts to force employers and unions into arbitration where strikes were excessively violent, or where picketing rules were breached or to declare such a strike unprotected, seems a rather fair attempt at reaching that balance. I believe we, as a nation, should earnestly discuss, debate, engage and make a concerted effort towards finding an alternative, rather than hide behind general statements that deny responsibility or accountability for the havoc that protracted and violent strikes are causing.

On a positive note, it seems we have a starting point: even the union leadership is denying and denouncing the violence. Do they have or do they lack the integrity to do something about it? At present, Cosatu is opposing the DA’s call for Government intervention, but I believe it is time for everyone to wake up and to stop this madness. Unless what we really want is an ‘African spring.’

Many Steel Award 2014 entries reflect steel’s popularity for social investment projects

The Southern African Institute of Steel Construction (SAISC) reports that many of the more than 60 entries into Steel Awards 2014 reflect how steel has become the material of choice in a growing number of social investment-type projects.

“This is in large part due to the long term energy-saving properties of steel, as well as the savings brought about through the speed of erection and generally more efficient construction processes that steel generally offers compared with other commonly used materials,” says SAISC education director, Spencer Erling.

He adds that each year the ability of South African architects and engineers to build aesthetic steel structures becomes increasingly apparent. “The quality of the entries improves each year and 2014 is no different,” says Erling. “Given that aesthetic steel structures are now so achievable in this country and add to this the all-round efficiency properties of the material, it’s no wonder steel is being used more and more in projects where capital funds are tight and sustainability is the essence,” he says.

Three such projects have, according to Erling, caught the eye of the judging panel: the Tugela River Bridge, the American International School of Johannesburg (AISJ) Aquatic Centre and the Lutheran Church Outreach Foundation’s Hillbrow Dance Hall.

TUGELA RIVER BRIDGE (DEVELOPER/OWNER: KZN DEPARTMENT OF TRANSPORT)

This project consists of a 134m-long structural steel suspension bridge. The suspension portion consists of two equal spans of 60m constructed over the 8m deep Tugela River at Kwajolwayo, upstream of the Tugela Ferry in the Msinga area of rural Kwazulu Natal. The bridge provides a life-changing, safe passage over the Tugela River for people residing on the North and South banks of the river, giving them access to employment opportunities and schools on the opposite side of the river.

The concept for the bridge was developed from the need to carry a narrow pedestrian walkway across the 134m between riverbanks and its design was controlled mainly by the fact that the higher the mass of a structure, the more the material required to build it, with the corresponding cost inflation.

“Thus, every effort was made to keep the material content of the structure as low as possible whilst providing sufficient strength and stability to meet the client requirements for a safe pedestrian river crossing,” said the project team. They added that the inaccessible, deep gorge provided an ideal situation for this type of structure, which would have to be erected by hand or with light, hand-operated equipment and that structural steel was chosen as the ideal material to meet these requirements.

The bridge, which was constructed using labour sourced from the local community, has already received a commendation from the SAICE Joint Structural division for technical excellence.

AISJ AQUATIC CENTRE (DEVELOPER/OWNER: AMERICAN SCHOOL OF JOHANNESBURG)

This 1 400m² facility features a six-lane, 25m pool with an additional shallow teaching pool, enclosed changing areas, office space, storage space, and mechanical room.

According to the project team, the Aquatics Centre is a purposely-designed all-weather facility incorporating special design features that take environmental, operational and economic factors into account. These include the erection of tensile structures and mechanical louvres on the façade, solar panels on the roofing structure and a hybrid solar and gas heating system for the change rooms.

The tensile structures facilitate natural light and airflow through the building and are complemented by the horizontal mechanical louvre system to the southern side, which provides additional airflow and light into the interior.

The tubular steel frame of the building comprises of 273mm diameter circular hollow sections in a ‘scissor’-type geometric arrangement. The ‘scissor’ geometry of the circular hollow sections is further emphasised by the purlin cleats, which elevate the purlins from the structure in order to elevate the sheeting.

All the innovative designs and fabrication achieve a continuous, smooth-flowing structure, similar to that of the smooth surface of the water in the swimming pool.

HILLBROW DANCE HALL (DEVELOPER/OWNER: LUTHERAN COMMUNITY OUTREACH FOUNDATION)

This dance hall and community centre serves the local community and houses offices for the Lutheran Church.

Light steel frame construction was chosen for the project due to the structural requirements of building a three-storey building on top of an existing basement.

“A conventional building would have been too heavy, says the project team, “and the utilisation of light steel was the answer.” They added that the building is exceptionally green for several reasons: being infinitely recyclable, steel is energy efficient; the

external cladding allows for incorporation of thermal insulation for reduced energy bills; the open-light features allow for light without energy consumption; the vented approach allows for natural cooling; its use of recycled thermal insulation.

A large amount of specialised detailing was required from the main contractor in order to incorporate the unique vision of the architect and his ‘truth to materials’ philosophy. Very little in the building was ‘off the shelf,’ thus requiring a significant degree of detailed design.

Ultimately, this building not only showcases in a most aesthetic way the materials of construction, but it also clearly demonstrates the possibility of ‘repurposing’ previously unusable spaces through innovative thinking and design.

Erling says that, at the time of writing, the judging process was under way and that the results will be announced at the Steel Awards 2014, which takes place on 18 September in Johannesburg, Cape Town and Durban.

RY Quick fix Butyl Tape

Winter is here, and now is the perfect time to fix up those drips and leaks. Butyl Seal brings you handy tips for tackling roofs that were not

sealed with Butyl Tape during construction.

LAPSEAL If you are feeling particularly energetic, undo your fasteners, lift the sheets and apply a strip of 8mm x 3mm butyl tape to the edges to ensure a watertight seal.

If sheets are slightly uneven, it may be better to use an 8mm diameter (round profile) piece of Butyl Tape to compensate for the gap. A round profile flattens out to allow for any unevenness in the sheets. Butyl Tape is perfect to use on galvanized sheeting, polycarbonate sheeting and most other types of roof sheets.

STICK AND PASTEA great benefit of this method is that it can last many years. Butyl Tape is fully paintable and can therefore blend in with existing sheets.

Butyl tape is 100% UV protected, so even if the tape is not painted over, it will still last many years.

For a quick and long-lasting solution to a leaking roofing sheet, use a 25mm x 3mm strip of Butyl Tape along the joint without having to loosen or lift it.

FASTENER SEALFasteners can leak and become loosened over time. A patch of Butyl Tape is all it takes, once the fastener has been replaced or tightened, to seal it permanently.

There is no better way to ensure that water does not leak through fasteners than Butyl Tape. This product will expand and contract with the sheets, ensuring a permanent watertight bond.

LSF

B SASFA ventures cross-border with Light Steel Frame Building training

After significant success with growing the light steel frame building (LSFB) method in South Africa in a relatively short time, the Southern African Light Steel Frame Building Association (SASFA) has embarked on taking the LSFB

message to other Southern African countries.

John Barnard, SASFA director, says that while the growth of LSFB in South Africa has been phenomenal, it has not been surprising. “The advantages of the method in terms

of ease and speed of construction and the significant long-term energy savings make its popularity in this country quite logical as developers come under increasing financial pressure. Increased efficiency is the name of the game in construction the world over,” says Barnard.

Barnard says that it was always SASFA’s intention to spread LSFB throughout the Southern African region, but it has waited until the local effort was up and running.

“We wanted to focus on the South African market until all the issues were ironed out and a deep level of institutional acceptance was attained. We have reached that point and now we can spread our wings,” says Barnard.

While LSFB awareness seminars have previously been presented in Namibia, SASFA’s first cross-border training initiative was a 6-day course for building contractors in Windhoek, Namibia.

LSFB

“While this was the fifteenth time we have run this course, it was the first beyond RSA borders,” says Barnard. “We had 21 attendees: 60% from Namibia, 30% from the Democratic Republic of Congo and the rest from Zambia. The interest from the neighbouring countries is indicative of the growing awareness of LSFB in Sub-Saharan Africa,” says Barnard.

The candidates were from a range of disciplines – builders, carpenters, technicians, two architects and an accountant. Eight of the attendees were from SASFA member companies.

The 4-day section on steel frame manufacturing and erection was presented by Barnard and well-known consulting engineer, Richard Bailey. The day-and-a-half section on cladding, lining and insulation was presented by Andrew de Klerk (Everite) and Willem Venter (Lafarge Gypsum).

The full range of topics, from foundations and the properties of the materials, to erecting and bracing wall panels, and erecting roof trusses was covered. Also, as in the past, Speedfit Africa illustrated their plumbing system.

“Not only were students advised on the correct way of doing things, but it was also explained to them why certain aspects were particularly important,” Barnard says.

On request from WML Global from Namibia – a recently-joined SASFA member – the practical work was done on a structure they wished to erect in an industrial area outside Windhoek. They had prepared a 4.5m x 3m slab on which a light steel frame structure was to be erected by the students, as part of the practical component of the course.

Cladding, lining and insulation materials were supplied by Lafarge and Everite for fixing to the steel frame. Marshall Hinds supplied the building wrap and Kare the fasteners for fixing the boards and Lafarge also illustrated how a damaged gypsum board panel can be repaired.

The students had to write two tests to assess the level of their knowledge. They were also asked to rate the course on a daily basis, covering aspects such as venue, arrangements, course content, course notes and presentation. “The average rating covering all aspects was in excess of 90%, and judging by the students’ response, presentation of the course was certainly successful,” Barnard says.

SASFA has to date issued 228 certificates for successful completion of the LSFB course for building contractors.

This 6-day course for building contractors will again be presented in Durban (6-12 July 2014) and either in Cape Town or Gauteng in October 2014.

LET’S TAKE A BRIEF WANDER THROUGH THIS EXTRAORDINARY RESIDENCE AND DISCOVER THE FUTURE OF GREEN LIVING:

• The house is powered by roof-mounted solar photovoltaic panels, with a bank of zero-maintenance batteries charged by two inverters, giving the house autonomy. Further panels power the pool pump during daylight hours.

• Active and passive energy saving is achieved through LED lighting, energy-saving taps and shower heads, flat-plate solar water heating and heat pumps, double glazed windows, polycarbonate sheeting for light harvesting, including skylights, underfloor heating through solar heated and stored water, along with water heating from the fireplace, gas cooking from recycled organic waste, Envirotuff roofing insulation, etc. Cooling of the house is achieved through a thermal tower that extracts warm air passively via the highest point, as well as through piped underfloor water cooling. The wine cooler benefits similarly.

• Water sustainability is achieved through significant

rainwater harvesting, storage and recycling. 30 000ℓ of storage tanks were installed. Harvested and waste water are treated using ozone and filters. Aquagardens that form part of a complete loop along with reed bed systems serve to naturally purify waste water. Such a loop includes the swimming pool. The driveway is made from the porous concrete product, Hydromedia, through which all rainwater drains immediately and is collected underneath before flowing into the water recycling process.

It is estimated that nearly 60% of the world’s electricity is consumed by residential and commercial buildings, and the building sector is the single largest contributor to

greenhouse gas emissions. Yet the cleanest form of power generation is the energy you don’t need to generate – through the correct design of solutions to suit the industry.

WHAT IS AN ENERGY EFFICIENT BUILDING ENVELOPE?

Metal roof and wall systems are considered energy efficient when they directly contribute to a reduction in the carbon emissions and also the operational energy costs of heating and cooling the building itself. When people think of energy efficient or ‘green’ roofs, they consider options such as solar panels, wind turbines and green or sedum roofing systems. But there are easier, cheaper and more effective solutions to providing energy efficient roofs.

ROOFING AND THE SANS 10400XA LEGISLATION

Since the legislation came into effect, all new buildings must have insulation installed and a stipulated R-value needs to be achieved. When the requirements of SANS 10400XA are correctly applied, energy efficiency must be reached in one of the following ways:

• Shading or insulating the building

• Heat flow control through the building

• Air leakage needs to be controlled through building fabric

• Air movement for cooling needs to be created for cooling

• Cooling and heating of water systems need to be improved

Y A higher standard in energy efficient roofingMany countries around the world have not had to concern themselves with energy efficient building envelope solutions, as their costs to cool or heat buildings have

been traditionally low. However, the hunger for energy is constantly increasing and spreading globally, and with regular load shedding becoming a very real contingency

to deal with in South Africa, the strain on the generation of power is evident.

AUGUST 201428

Page 31: SA Roofing August 2014 | Issue: 62

OPTIONS FOR ENERGY SMART BUILDING ENVELOPE SOLUTIONS

High-quality, simple-to-install solutions, complete with good detailing and workmanship are essential to achieve compliance – not just for the day of installation, but the long-term operational use of the building.

• Implementing energy efficient metal roofing and cladding system designs (with roofs with U-Values of 0.25 W/m2K and walls of 0.35 W/m2K) as well as sealing the roof to the walls (thereby reducing the air permeability within the building) will achieve a significant reduction in cooling/heating operational costs.

• Thermally efficient support systems for the building envelope can effectively reduce the transfer of heat or cold bridging, for example 'Helping Hand Brackets' for cladding and rainscreen systems, and 'Ashgrid Bar & Bracket' for roofing systems.

• Specialist waterproofing coatings such as ceramic or silicone systems reflect the sun’s rays by up to 90%, thereby reducing the temperature in the building and the requirements for cooling.

SAFE, ENERGY EFFICIENT DESIGN OF METAL ROOFING SYSTEMSIn contrast to the installation of a single-skin roof application, which may be coupled with thin laid insulation and cables using boards and walk purlins or rafters, safe-to-install, thermally efficient metal roofing design solutions demand the use of steel walkable liner sheets over the purlins for new builds, or the existing roof sheet for refurbishments.

MRC Group is heralding the use of high-quality, simple-to-install, easy-to-design and safe thermally efficient building envelope solutions that provide energy savings for the operational life of the building, thereby setting higher standards in system design and installation and reducing the strain on the generation of energy.

Built in two phases, the first phase comprising of a gross lettable area (GLA) of ± 3 100m² and the second phase 3 700m² GLA, the project was the initiative of local

property developer, Krisp Properties.

“We already had a lease agreement with Michelin Tyre Company South Africa for Phase 1 well before the first sod had been turned, which meant we only had seven months to erect the building,” said Jordan Mann, executive director of Krisp Properties.

Francois Marais of Francois Marais Architects said the construction of the buildings embraced new energy efficiency legislation rather than being restricted by it.

“The design uses overhangs above all the windows and doors to minimise the impact of the sun and to reduce the escape of heat from the buildings,” says Marais.

Completed by the end of November 2013, Phase 1 comprises two double-storey buildings, each measuring 1 550m² (GLA), which are linked by a central entrance atrium.

“We deployed hollow-core slabs for the first floors as well as the roofs, and this assisted us in reducing construction time by several weeks. Hollow-core slabs were used for the roofing which would allow the necessary support for the installation of photovoltaic power generation units in future. Moreover, the roofs have created ideal catchment areas for harvesting rainwater which is to be stored in subterranean tanks,” said Mann.

Echo’s prestressed hollow-core slabs were specified by PDS Civil and Structural Engineers and slabs totalling ± 3 100m² were used for phase 1. Phase 2 will make use of ±3 750m² of Echo slabs. Slabs up to 10m were deployed on the first floor sections and slabs of between five and seven metres were installed on the roof. Both the first floor and roof panels were topped with steel reinforced screeds and a bitumen coating was used to waterproof the roofs. In addition, Echo also supplied nine metre H-shaped universal steel columns to provide slab support for the internal cantilevering.

According to structural engineer, Spiros Sdralis, of PDS, Echo’s role involved considerably more than simply supplying the slabs.

“We provided Echo with a set of drawings and they then prepared a layout which took all the servicing requirements into account. Echo’s engineer, Daniel Petrov, was involved from the outset and he was always on site when we needed him, particularly in solving specific on-site challenges,” said Sdralis.

“For example, some of the slabs had to be modified so that the upper-section of steel skeleton could be anchored to the first floor on a solid platform. This meant that the hollow-core end sections of some slabs had to be packed with concrete to provide the solid base. Echo filled in the voids with concrete according to our specifications and this enabled us to drill out the holes for the bolt anchor sleeves in the same way we had done on the ground floor.”

The upper-level steel framework of Phase 2 which was bolted to solid concrete section of Echo slabs.

“The builders were able to begin the assembly of the upper level steel frame as soon as the slabs had been installed and this was the prime advantage of using hollow-core slabs. If in-situ flooring had been used it would have delayed the completion dates on both buildings by several weeks.”

“Extensive use was made of cantilevering on this development, both internally and for the shade overhangs, and Daniel assisted

with redesigning some of the cantilever sections on Phase 2. He also helped us with changing the direction of some of the slabs.”

Echo also allowed for service ducts based on the architectural plans and suspended ceilings were created 600mm below the soffits of the roofs and first floors to accommodate electrical, plumbing and air-conditioning services.

Trina Solar Limited (TSL), a global leader in photovoltaic (PV) modules, solutions and services, donated solar modules of a total output of 9.5 kW

for the Msafiri English Medium Primary School in Tanzania.

The transportation of the modules to the project location and the construction of the solar system were organized by the companies, SunPlan and MaxSolar, developer and operator of solar power plants and both partners of Trina Solar.

The installation of the PV system was finalized in March with the support of Hutterer GmbH and locals were trained for its maintenance. For this project, poly-crystalline solar modules from Trina Solar with an output of 230W were used.

The Msafiri School is an officially registered Non-Government Organization (NGO), founded by Michael Hell (Ampfing, Germany) and Grace Msafiri (Kisangara, Tanzania). Its establishment 2004 was mainly funded by donations from Mühldorf, where SunPlan and Hutterer are located.

170 children are attending the school that earned a good reputation for the quality of its education. Because of the weak electricity grid electrical light is not always available. Now the Trina Solar modules enable the school to use computers at any time of the day, as well as to take care of the children and guarantee their safety in the evening after dark.

“We are very happy that we can support the Msafiri School and thereby also the education of 170 children with our solar modules,” says Ben Hill, President of Trina Solar Europe. “This project shows in a very impressive way that photovoltaics is a reliable and sustainable source of energy – even in regions which are not yet connected to the grid. In cases like this one, photovoltaics can even make an important contribution to society.”

50 GOLDEN YEARS The Pekay Group is a family-owned speciality chemical company. Established in 1959 by the late W.Z. Poklewski–Koziell, a Polish immigrant to South Africa, the company has grown over the last half century to be one of the largest privately owned adhesive producers in Southern Africa. It is 100% South African-owned. With manufacturing plants in Johannesburg, Durban, Cape Town, Port Elizabeth, Botswana and Zimbabwe, it has branches and distribution depots in all the major regions countrywide.

SUSTAINED GROWTH AND DEVELOPMENT Driven by market trends and industry demands over the years, expansion and diversity became essential. Within the group, specialist manufacturers like Pekay Adhesives & Coatings, Jayco Sealants and Admac Hotmelt & Equipment are now producing and supplying a vast range of superior quality adhesives, sealants, coatings and waterproofing chemical compounds for the building, flooring, construction, printing and numerous other industries. World famous brand names like Bostik Industrial Adhesives and Copernit Waterproofing products have subsequently been introduced to the wide range of high quality products on offer. All of these products are supplied under exclusive licencing and distribution contracts.

The Pekay Group has supplied a number of waterproofing projects to date, including a number of high profile structures like the Walker Creek Phase 1 (the new offices for SARS), the South African Reserve Bank and Pretoria City Hall, all in Pretoria.

The roof of the new SARS offices in Walker Creek Office Park in Pretoria, spanning an area of 1 500m2, was waterproofed using 4mm Copernit Dual Carrier Torchon. The project was contracted locally, and phases 2 and 3 of the project are to follow.

ROLLFORMING EVERYWHERERollforming of sheet metal plays an integral role in the building and construction of commercial and industrial structures and in the automotive industry.

We come across things that have been rollformed every day without taking notice of them: guardrails that keep cars from going over the edge on the road, ceiling tees, roof sheeting, stud and track, purlins, shelving, air conditioning, ventilation, window frames, door frames, balustrades, flashings, gutters and downpipes, motor vehicle parts, truck parts, trailer parts, and so much more.

PRE-ENGINEERED ROLLFORMERSMetal rollforming can be an intricate process. Precision and accuracy are fundamental in the rollforming process to ensure a high quality end result. Many a company has built their own rollformers and often they work if run at slow speed without any intricate punching and where precise length and spacing are not critical. But for fast accurate outputs, top-of-the-range machinery is required.

The top rollforming machines cost a lot of money, because they are designed by qualified and experienced mechanical and electrical engineers using the best systems and materials available.

They are also guaranteed to produce the final product without huge amounts of wastage due to poor engineering. This kind of accuracy in the end product only comes from using top quality machines that are perfectly engineered, and that come at a price to match.

LABOUR IN ROLLFORMINGFaced with an increasingly uncertain and volatile global economic climate, many businesses today are seeking alternative ways to cut costs in an effort to ensure that profit levels remain optimal. The rate of technological breakthrough in the realm of industrial machinery is reducing the need for manual labour.

Modernisation in the workplace is an inescapable reality facing today’s factory owners. The cost of machinery relative to the cost of labour and materials means it is now cost effective to use quality high speed automated equipment above manually operated, labour intensive machinery.

Rollforming can be labour intensive, where each small machine does one specific task and is perhaps only managed by one machine minder. A manual labour intensive manufacturing process that is open to human error and resultant losses in productivity and production is becoming a clear reality.

Companies who have moved towards automation have seen a resulting increase in hassle-free production, and an unmistakeable growth in their competitive advantage.

“Spending money on high tech equipment adds value to your business, makes it more competitive, and reduces the headache of many labour issues,” says Greg Fuchsloch, CEO of Metalforming Technology SA, one of the leading suppliers of metal processing machinery. “It also means you up-skill your staff, giving them a better understanding of the job on hand, giving you a faster turnaround time and a greater competitive edge. Automation is fast becoming the future in the production of steel parts.” Inline punching, cropping forming and bending are fast taking place over multiple processing stations.

As global demands for services and products continue to rise, the need for faster, higher output, reliable, time-saving and cost-effective machinery has become essential for companies wishing to remain competitive and profitable in the marketplace today.

The worldwide market and demand for machine tool products, encompassing metal cutting machine tools, metal forming machine tools and machine tool accessories are estimated to increase by 6.9% per year through to 2014, reaching $108 billion in total revenue.

“It is possible today to have a rollforming line that produces 160m per minute,” says Greg. “Our top-of-the-line machines can be run by one person on the floor, while the manager sits at his desk keeping an eye on the output of the line on his computer, in real time. No longer does he have to run to the floor to find out which job is on the machine and give vague ‘guesstimates’ of when a job will be ready. We are talking about having your finger on the pulse of your business, your output and your profitability.”

Machinery today is a far cry from that found even as little as 10-15 years ago. As global demands for services and products continue to rise, so has the need for faster, higher output, more reliable, time saving and cost-effective machinery.

“As always, however, there is a downside to automation,” says Greg. “With businesses across the globe gradually phasing out their needs for large manual workforces, and switching to automated machinery, it really is only a matter of time before workloads that have, until now, been carried out manually, are achieved entirely through the use of machinery. Our country needs businesses that employ and educate staff; this is the key to economic prosperity and social stability.” However, the economics and reality of labour issues continuously push toward automation.

ADVANTAGES OF AUTOMATED MACHINERY IN YOUR WORKPLACE:

• Speed of production increases dramatically. • Superior safety system with fewer injuries on the job. • Auto gauging allowing for setting of the rollfomer within seconds. • Auto stacking allowing the packing of materials without handling by human

intervention. • Dual decoilers with coil carts reducing damage to coil inners. • PLCs with remote management control systems. • Labour costs substantially diminished, as well as related labour issues. • Workloads are easier to manage with the ability to calculate exact production

costs and time taken to produce parts.• Increased production capacity• Less wastage and better yields and better quality produced products• Up-skilled staff applying more input and value to companies.

DISADVANTAGES OF USING AUTOMATED MACHINERY IN YOUR WORKPLACE:

• Not all automated machines are created equal and great care needs to be taken when placing your order to ensure that the outcome matches your expectations, specifications, and budget. Deal with reputable companies and companies who have experience in the industry.

• The more hi-tech the machine, the higher the price. However, businesses need to see them as an investment for the future. The cost of good equipment is low compared to inexpensive machinery that later turns out to be very costly.

• Breakdowns can be costly, closing down the entire production line, so care needs to be taken that you are buying a quality machine that offers the least amount of downtime.

“Management and staff also need to undergo a significant change in mindset and modus operandi,” says Greg. “Allowing workloads that until now have been achieved by a manual workforce to be carried out by machinery sometimes takes a little getting used to.”

Do these machines herald the demise of the labourer and the dawn of the machine for metal rollforming and processing? It is an undisputable reality that machinery has already replaced the human hand in nearly every other industry, from motor cars to clothing and consumer goods. Sentiment is losing out to profits once again as the labour finds themselves at the wrong end of the stick.

“Each business has to decide what is best for its clients and staff alike,” says Greg. “Every business is unique and has a unique set of needs and expectations set by the stakeholders. This and other factors will determine whether automation is on the cards or not. It’s definitely not for everybody.”

To address this, a new widely-acclaimed welding simulator is now available in South Africa as a cost-effective alternative to traditional training and provides the same

level of skills and with cost savings of at least 40%.

“The Soldamatic simulator, which won top honours at this year’s Worlddidac Awards for the most innovative educational product for 2014, requires no costly welding consumables and reduces training time by half,” says Bez Sangari, CEO Sangari South Africa, sole distributors of the product.

“No materials such as welding rods, steel plates or oxygen are needed and because the equipment has no gas emissions it is eco-friendly,” he says.

“In addition, it offers a safe environment with no need for special clothing or ventilation. The welding can be done in any classroom. It is 100% safe, simply because it is a virtual welding environment.”

“The system is sophisticated in providing augmented-reality 3-D vision in a workshop environment. Payback for a large training institution is about 18-24 months. The quick payback period is achieved because no materials are used and there is no wastage,” Mr Sangari says.

The simulator consists of a hardware unit the size of a standard PC, with a built-in screen that allows the trainer to view the student’s progress in real-time, as well as it being recorded. The trainee wears the virtual-reality headgear which simulates a real welding environment.

The headgear generates realistic welding graphics such as the weld pool and beam. It emits simulated smoke and sparks and simulates heating of the affected area, all through the student’s headgear. It also simulates cracks, filler material, gravity and undercutting.

“Welding skills can be trained for specific applications and the student’s performance measured in a fair, reliable and unbiased manner. The unit includes 93 different training lessons and customised lessons can also be added,” says Mr Sangari. Both the trainer and trainee are able to analyse and assess the welding performance in a video format afterwards and evaluate skills such as the welding velocity, stick out, travel and working angles. When required, maintenance and upgrades of the software can be done remotely.

The system supports SMAW, GTAW and GMAW processes and a variety of welding joints such as V-butt joint, Lap, T-joint, pipe to square butt joints and pipe T-joints and a variety of angle welding exercises.

Specialised Exhibitions Montgomery, the organiser of Interbuild Africa 2014, has partnered with the South African Institute of Architects (SAIA) on its OpenArchitecture

Initiative, which is the first of its transformation projects aligned to Skills Development. The OpenArchitecture programme offers architecture education in the form of a synthesis of face-to-face, block release, online and office-based architecture education. This initiative is aimed at students that wish to advance their qualifications, but are not in a position to attend full-time university studies.

According to Gary Corin, Managing Director of Specialised Exhibitions Montgomery, Interbuild Africa will sponsor three bursaries to the value of R10 000 each, which will be awarded to the top three, first year OpenArchitecture students. The value of this bursary will cover each student’s tuition fees, to complete their second year of study.

“We’re very excited about the opportunity to contribute to this initiative through our partnership with SAIA and OpenArchitecture,” says Corin. “This award will provide each of the winning students with an exceptional opportunity to showcase their projects and to successfully complete the advancement of their education,” he added.

According to Lone Poulsen, the Programme Director for OpenArchitecture, this awards initiative is aimed at students in need.

“The OpenArchitecture students will be judged on the quality of their 2014 mid-term assignment submissions, by a panel of judges from OpenArchitecture, the Cape Peninsula University of Technology and SAIA,” she says. “The criteria for the awards will be based on a combination of academic record, merit and each individual student’s unique circumstances,” added Poulsen.

The three students selected will also have the opportunity to showcase their projects at Interbuild Africa 2014.

“The Interbuild Africa team is delighted to showcase industry innovation, and empower talented individuals in partnership with some of the leading industry bodies operating in this sector today,” says Corin. “We look forward to finalising the results of this initiative and showcasing these award-winning projects at this year’s event,” 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.

Speaking at a recent Master Builders Association North (MBA North) business networking breakfast, Prof Maritz said the effects of such late payments were

severely hurting an industry already facing several major challenges.

“Smaller and emerging contractors are most prone to be negatively affected and even ruined by late payments. It is worrying that regulations mooted by Master Builders South Africa and submitted to the National Department of Public Works (NDPW) by the Construction Industry Development Board, for promulgation, have still not been acted upon nearly four years after first being drafted,” he stated.

Prof Maritz said countries such as the UK, Singapore, New Zealand and Australia had gone beyond regulations with specific construction legislation put in place to protect contractors against late or non-payment. “We feel the draft regulations submitted to the NDPW are a move in the same direction although, even if accepted, the local industry would still be years behind those countries in terms of refining the laws and getting Government and all other parties involved to co-operate.”

“The draft regulations address some of the major causes of late payments, contractual issues and disputes, as well as the rights and obligations of each party. It also seeks solutions that may mitigate lengthy court battles and works on the premises that as long as all parties involved understand the requirements of a project, there will be fewer disputes in future. We also need to put in place set standards of uniformity and standard documentation to ensure everyone understands the contents of a contract.”

He said this would increase cost efficiencies and provide uniformity in procurement, as well as making tendering easier and more precise. He also urged all parties, including Master Builders South Africa, to maintain pressure on regulators to fast-track the proposed legislation, especially parts relating to prompt payment protection and adjudication in the event of a dispute. “This would allow a more nurturing environment for contractors and SMMEs in future,” he told the meeting.
