Small product – big problem! It is most probably the smallest and cheapest component of a metal roofing structure, but a poor quality roofing washer can play a significant role in promoting corrosion and causing accelerated deterioration of roofing materials.
These fasteners are exhibiting corrosion caused by a conductive washer.
A
common belief exists that as long as a roofing fastener has a washer, it will do the job. This, however, is not true. To understand the necessity of identifying and using quality washers and seals, it is important to first understand the function of a washer in a roofing system. A washer must be able to withstand all the environmental elements it is exposed to. These include UV degradation, salts from marine environments, acid from industrial pollution, rain, extreme heat, fumes and gases from within factories and plants, etc. While exposed to these conditions the washers must remain elastic, intact and watertight for the life span of the complete roofing system. The cost of washers is a fraction of 1% of the cost of a roof, yet many companies will cut corners when selecting washers and opt for a lower price rather than a decent quality washer. It is a surprisingly little known fact that some washers can play a significant part in the corrosion of a roof system and can even accelerate deterioration, reducing the life span of the structure if incorrect or substandard washers are installed.
Beware of blends Washers are made of a variety of materials but few are suited to the harsh conditions to which they are exposed. EPDM – a synthetic polymer derived from oil - is the ideal material from which to manufacture washers. Many companies state that they supply EPDM washers, but because there are currently no standards in place that specify the percentage of EPDM required in the washers, the EPDM contents vary greatly. The number of ingredients in any given EPDM blend can range from 5 to 20 with hugely varying properties, such as UV stability, elasticity, compression resistance and resistance to heat ageing. An important washer additive is carbon black. A small amount of carbon black is required in the EPDM blend as it offers important performance characteristics at a relatively low cost.
4
These characteristics include: • High UV resistance • Improved elasticity • Weathering resistance • Assistance with manufacturing methods The low cost of carbon black makes it effective for binding blends with high clay contents. As rising oil prices lead to an increased price of EPDM, some manufacturers increase the level of fillers in their blends in order to keep costs down. These low EPDM, high carbon blends are almost impossible to distinguish visually from high quality blends that have a life span in excess of 20 years. A poorly blended formulation can last as little as 18 months before showing signs of deterioration.
Conductive corrosion Another concern caused by high levels of carbon black is the occurrence of bi-metallic corrosion facilitated by the conductive washer. The quantity of carbon, grade of carbon and its dispersion in the blend can lead to an electrical pathway being developed through the washer itself. This occurs when the high levels of carbon black form a conductive chain through the polymer and create an electrolytic cell between two different metals –that of the screw and the roof. This problem is often misinterpreted as a failure of the fastener or roofing/ cladding material. This is an inaccurate and costly assumption. An indication that the washer is contributing to the corrosion can be small blisters of white rust on the surface of the steel sheet close to the base of the screw head. In severe cases, you will see red rust as the coating is removed and the substrate of the roof sheeting begins to corrode. In addition, where the corrosion has remained unchecked, the structural integrity of the construction envelope will have begun failing.

From left to right: Corrosion on coloured steel with a mildly conductive washer, semi-conductive washer and highly conductive washer after 10 months' exposure.
It is advisable to ask for a certificate of compliance from a screw supplier or a similar statement regarding conductivity. You can also perform the test yourself with a simple multimeter. Recently, a major supplier of roofing and cladding material in Australia (also represented in South Africa) made the recommendation that all roofing and cladding must be installed with fully non-conductive washers. The conclusion was reached after extensive real-world testing was carried out and revealed that washers with even the slightest conductivity showed an increase in electrolysis compared with fasteners with non-conductive washers. This recommendation is to be adopted as part of the company’s overall roof material warranty.
By applying a charge of 1,000 volts across the washer and reading the resistance, it was determined that this washer is conductive.
Quality washers are engineered to suit the fastener, roofing and cladding profiles and materials, as well as the final application. The old terminology of ‘one size fits all’ creates false assumptions and can lead to leakages caused by poor design.
When looking for a quality washer, always ask your fastener supplier the following questions: • Does the washer have a warranty? • Is the washer quality traceable (who made it)? • Is the technical data and support available to be viewed? • Has the washer been manufactured to suit the fastener and application that I am using it for? • How can I tell I am getting what I am paying for?
Sparks appear when current is applied to a conductive washer.
A simple test Testing the conductivity of a washer can be done simply by applying a resistance meter to the surface of the washer. Applying a charge of 1,000V across the washer and reading the resistance will provide a quick indication of whether or not the washer is conductive. The true measure of a perfect insulator, which is what a washer should be, is a reading of infinite resistance regardless of the voltage applied.
By asking these simple questions, you can be assured that your next metal roofing project will not fail because of the washers. (Amended and adapted by R. Hylkema from an article by Andrew Meese from Deks Industries, Australia.) DEKS is a leading manufacturer and supplier of roofing flashing, roofing washers and plumbing products throughout Australia and the world.
The degree of conductivity is measured according to the amount of current that will pass through at any given voltage. The industry benchmark equates to a resistance of no less than 2000M Ohms.

Groundbreaking Singapore
Research at SteelFuture Conference Prof. Richard Liew, Program Director of Hazard, Risk and Mitigation in the Department of Civil & Environmental Engineering at the National University of Singapore, says that one of the exciting results of the current research that is taking place at the National University of Singapore and JFE Steel Group in Japan is on high-rise building construction using concrete filled tubular columns filled with ultra-high strength concrete and high strength steel.
P
rof. Liew is one of the key presenters at the SteelFuture Conference to be held at the Sandton Sun Conference Centre in March 2013.The main sponsor of the conference is Cadex SA. “Steel box column sections which are fabricated from high strength plates with tensile strength up to 700 MPA may be in-filled with ultra high strength concrete with compressive strength up to 180MPa to free up usable space in high rise buildings. The column size can be reduced by up to 50% for high-rise building greater than 50-storeys in height. This will enhance usable space and provide higher return on investment in high rise buildings. The research involves the fundamental development of high strength materials, mechanical behaviour and fire-engineer solutions of utilising such components in tall building construction,” says Prof Liew.
Figure 2:The Flower Dome and the Cloud Forest conservatories located near to Marina Bay Sands Hotel and Sands Skypark observation deck.
With respect to ground-breaking projects that will have significant effects on future construction, Prof Liew cites The Gardens by the Bay, located in the heart of Singapore’s downtown Marina Bay, as one of the world’s most important projects. “It is one of the largest and most advanced projects ever undertaken in this part of the world,” says Liew. “Key features of the development include two energy-efficient steel and glass sculptural conservatories (see Figure 2) which utilize the latest sustainable building technologies, which include a series of steel arches connecting to the gridshell by steel hangers. The arch was in-filled with concrete up to a height of 8m above base level to achieve higher sectional moment capacity. The main role of the arches is to strengthen the single layer gridshell to enhance its overall buckling capacity under gravity loads. The gridshell provides lateral stability against wind load and supports the glazing and other services.” Prof. Liew has been in involved in research and practice in steel concrete composite structures covering a wide spectrum of interests, including light-weight and high strength materials and advanced analysis of structures subject to extreme loads, for applications in offshore, marine, defence and civil infrastructural works. Arising from this work, he has coauthored five books and generated more than 300 technical publications. He serves on the editorial boards of eight international journals. He interacts closely with the industry in the Asia Pacific region serving as an expert and technical advisor and has been involved in numerous iconic steel projects. He chairs numerous international and national committees related to standards and specifications of steel and composite structures.

He is a key person responsible for the development of Singapore’s national annexes for the design of steel and composite structures using Eurocodes 3 and 4. Dr Hennie de Clercq, executive director of the Southern African Institute of Steel Construction, under whose auspices the SteelFuture Conference is being held, says that Richard Liew’s status in Singapore, China and further afield makes him a portal to a body of knowledge which is otherwise largely inaccessible to us. “Moreover, Singapore, according to our information, is one of the few countries in the world seriously considering Eurocode 3 (EC3), and Prof Liew will speak about their views and the research they did into the topic.” The SteelFuture Conference will take place at the Sandton Sun Conference Centre on the 5th and 6th March 2013.

20 years of constant Kare From humble beginnings in 1993, Kare Industrial Suppliers has grown into the market leader in roofing fasteners in Southern Africa. 2013 marks 20 years of supplying quality products to market and exceptional customer service for this roofing and cladding fastener giant.
W
ith six branches servicing South Africa including an export branch in Johannesburg, Kare is able to supply the roofing and cladding industry in Southern Africa with fasteners for every type of roofing application. Reitze Hylkema talks to SA Roofing about Kare’s 20 years of challenges and triumphs.
SA Roofing: Where did it all start and what were the initial challenges, if any, that Kare encountered as a young company? Reitze: In December 1992 the company where I was employed at that time unexpectedly closed down. Although there is no good time for a company to close down, December must be the most difficult time to find employment. In hindsight though, it was a blessing in disguise, as it became the motivating factor in starting Kare Industrial Suppliers. From a small office above a panel beating shop and operating as a genuine one-man show, Kare started on 15 January 1993.
With customers expecting accounts, but with suppliers not willing to grant credit facilities to a brand new company without a track record, the term ‘hand to mouth’ became very real to me. As a result of financial constraints, growth in the beginning was slow and limited, but ploughing back into the business resulted in a steady and healthy growth.
What do you think are the main reasons for Kare’s growth into the company that it is today? By structuring Kare’s distribution network on a franchise type of system, we are able to offer a nationwide service and build a nationwide brand while combining it with the commitment from the individual owners of the various branches. And by constantly innovating products and staying in tune with changes in the market environment, we have been able to initiate changes in the fastener market instead of being followers and imitators.

Stainless steel screws similar to those used on the Moses Mabhida stadium. What important achievements or milestones have led to Kare’s current success? A turning point for Kare Industrial Suppliers came when we had built up enough reserves to import the first small consignment of roofing screws that were made to our specifications. From the beginning, I realised that the quality of the roofing fasteners that were being used in South Africa fell way short of what they should have been, and it was my intention to change that and offer the industry quality fasteners. A second milestone was when Kare Industrial Suppliers was appointed as the official and sole distributor of ITW Buildex Teks screws in Southern Africa. This meant the introduction of Class 3 and Class 4 coated fasteners into South Africa. Being part of the SANS1273 technical committee, and eventually seeing the revised publication of the roofing fastener standard published in November 2009, was both a personal milestone and a huge improvement for the roofing industry.
Kare is celebrating its 20th anniversary this year. What does this mean to you and to the company? It has given me tremendous satisfaction to see most of our branches grow and become successful enterprises that offer employment to 27 people. In my opinion we have contributed to the raising of standards in the South African roofing market over the last 20 years and helped educate the market about corrosion protection on fasteners and correct fastener selection.

What is Kare’s flagship product and why? Our flagship product is the range of Buildex fasteners. As inventers of Teks self drilling screws ITW Buildex are world leaders in corrosion protective coatings and innovative fastening systems for the roofing, cladding and steel framing industries. Their constant research and development has kept them at the forefront worldwide and this has enabled Kare to introduce these products to the South African market. Examples are Buildex RoofZip and FibreZip screws, especially designed for fixing roof sheeting and fibre cement boards to thin gauge steel.
What are the three most prominent roofing projects with which Kare has been involved over the past 20 years? In 2002 Kare was successful in securing the order to supply stainless steel fasteners for phase 2 of the Mozal Aluminium smelter in Maputo, Mozambique. Despite very strong competition, the performance of the Buildex Taptite self tapping screws with trilobular threads outclassed all other fasteners in independent performance tests conducted by the CSIR in Pretoria. The 20 year warranty on the fasteners assisted further in securing the order and in excess of 500 000 screws were supplied for the project.

The event of the 2010 FIFATM World Cup saw the construction of six new stadiums and the upgrading of a number of others. Kare was privileged to have been a supplier of fasteners for all of the new stadiums. The Moses Mabhida stadium was an especially interesting project where 316 stainless steel fasteners were made to specification, which included drill points with a 12.5mm drilling capacity. The upgrading of many facilities, such as airport, train and bus infrastructure opened further opportunities for Kare to supply a wide variety of fasteners. More recently, the combination of Class 3 corrosion resistance, the drilling capacity of the Buildex Super Teks, and the variety of head styles available for different sheeting systems gave Kare the competitive edge which resulted in us supplying the fasteners for Medupi Power Station.
Moses Mabhida Stadium.
What’s on the cards for Kare in the next five years? And the next 20 years? With the track record of an innovative and progressive company, Kare Industrial Suppliers is excited about the changes in the roofing industry over the last few years. New energy efficiency regulations that were promulgated in 2012 have resulted in thicker and different types of insulation being specified for buildings. This has created a demand for longer and different types of fasteners, which Kare is currently developing. The increased popularity of thin gauge steel roofing battens has created a demand for fasteners with thread designs that offer good pull-out values in thin gauge steel. More and more fastener suppliers have started marketing fasteners with various types of coatings, making claims about compliance to SANS Class 3 and 4 standards. Most of these fasteners, however, do not conform to the specifications. We at Kare, therefore, will endeavour to initiate the regular testing of fasteners by an independent reputable body, preferably at real-world test sites throughout South Africa. This will ensure that only fasteners that conform to all the standard specifications will be sold and that substandard fasteners will be publically exposed.

The future of coil coating The advent of the Bronx Warehouse range of lines is gradually changing how companies perceive the coil-coating industry. Companies are learning that coil coating no longer requires a huge process line producing high volumes with large infrastructure and highly skilled operator and maintenance teams.
Exit section of the compact line.
T
he Bronx Warehouse Line is a cleverly designed compact coil-coating line that minimises the factory floor area and height required, which in many cases allows a line to fit within an existing warehousing area.
With lines starting at less than 60m long and fitting in less than 5m height, and requiring minimal foundations due to its flat floor design (a significant cost incurred with larger lines), more businesses are considering installing their own colour coating line to meet market demand. Neil Jones, General Sales Manager for Bronx International said, “Many stockholders and roll-forming companies supplying the construction industry experience the problem of having to carry large stock levels of coil, which in turn ties up their precious cash, which could be put to better use. They feel constrained by their reliance on and service from the larger mills and coil coaters, or by the need of having to carry undesirable stock levels to maintain customer service. After extensive research, we developed a solution to address this issue so that smaller companies could break into the coilcoating industry and provide greater opportunities for their business.”

Bronx has 13 references in Africa, including two warehouse lines installed in 2012. Two further warehouse lines are under construction and interest is growing as more companies look at the considerable benefits the Warehouse Line provides, including shorter lead times, which means you don’t have to wait for the coil to be delivered – it can be ordered today and painted tomorrow. Profit margins can be increased through the benefits associated with a reduction in coil inventory because you can stock a minimum quantity of coil. The Warehouse Line also enables you to expand your market share by offering specialty colours, short runs and early delivery, with greater control over the product, colour and finishes. In addition, Bronx International guarantees the quality of the line, product and paint finishes. This innovative system also enables you to charge a premium for customers ordering a minimum quantity, new colours or early delivery.

The Occupational Health and Safety Act How does it affect you?
Photo credit: gregor_y (http://www.flickr.com/photos/gregor_y/38130652/)
T
he Occupational Health and Safety Act (OHSA) (Act 95 of 1993) outlines a series of construction regulations to protect the safety of workers. One Property Holdings’ Heidi Franck reports that while many believe the Act applies strictly to property developers, OHSA actually applies to all construction work. Regulations 1&2 of the Construction Regulations (OHSA) define construction as “The construction, erection, maintenance, alteration, renovation, repair, demolition, or dismantling of or addition to a building or any other similar structure”

Why is compliance so important? “The Act is set up so that it is the employer, and not the contractor, who is responsible for compliance,” says Franck. “The penalty for non-compliance is a maximum fine of R100 000 and/or imprisonment. Ultimately, this means that it is up to the employer to ensure that the contractor is compliant with Act, as he will be liable for the penalty, due to non-compliance,” she adds.

“Yet today property developers and body corporates would be well advised to allocate additional budget to employ a Health and Safety Consultant on site. It’s a lot like insurance,” she laughs, “you don’t need it until you need it.”
h ea lth & safe t y
To this end, an employer must ensure that the contractor has registered with the Workmen’s Compensation Commissioner and that he is responsible for the health and safety of his employees. Furthermore, the contractor must have some manner in which to administer first aid should an incident arise and the means to transport the worker to a hospital should an injury occur. Finally, the contractor must report any injuries to the Department of Labour. “It is important that the employer ensures that the contractor signs a contract in which he agrees to comply with the OHSA,” Franck explains.
Despite the fact that the employer will be criminally liable for non-compliance with the Act – and short-term insurance will not cover criminal activity – there is a responsibility that lies with the employer to take care of the people working on his premises. “This entails ensuring that workers have all the equipment they require to carry out their jobs safely.”
The most important document in the process is a Health and Safety Specification, which requires that a risk analysis takes place. “In the past, the costs and administration around the Health and Safety Specification were the responsibility of the contractor. However, under the OHSA, this has now become the burden of the employer,” she informs, adding that in many cases, the contractor will be able to assist the employer with the process.
Indeed, Franck recommends the services of Health and Safety Consultants to ensure compliance in this regard. “Not only will they ensure compliance to the Act and take care of the process, they are also able to keep records which will assist should monthly Health and Safety audits be required,” Franck continues.
In some cases however, such as the building of a new home, the process will be beyond the capability of the employer and the contractor and the services of a Health and Safety Consultant will be required. “Twenty years ago, this job did not exist,” Franck muses.
Ultimately, Franck believes that delegation comes at a high price. “This applies most specifically within the property industry, where delegation will most likely occur to property managers. If you do choose to go this route, it is imperative that property managers are given the correct training to do the job properly. After all, the aim is avoid human tragedy at all costs,” she cautions.

Fall Protection Safety A fall, no matter how low or high, can result in serious injuries and even death. Workers often fail to weigh up the risks when taking chances and shortcuts. When working at heights, the last thing anyone should do is take risks.
I
n this article we look at the different types of fall protection systems that have been developed to eliminate any possible chance of a fall-related accident. It will also cover the role of supervisors and the responsibilities both management and workers have to ensure no one dies from a fall.
Physical Protection:
Fall Protection Plan:
Fall Prevention and Fall Arrest Systems:
Every site must have a Fall Protection Plan in place. This plan must be developed by a competent person that has been appointed in writing. This person must ensure the implementation of the Fall Protection Plan and ensure that it is updated on a regular basis. Programs within this plan must include Training, Inspections, Tests and Maintenance of equipment. Every person working at elevated positions must have been examined and granted a Medical Certificate of Fitness in order to do so. A healthy fit body is what is needed to work at these heights.
22
Guardrails, toe boards, safety nets, floor covers and personal fall arrest systems, like harnesses are all fall protection systems used on sites.
It is important to know the difference between fall prevention systems and fall arrest systems and when to apply them. Hand rails, floor covers and edge protection are all examples of fall prevention systems, whereas harnesses and fall arrest systems, like life lines, are examples of fall arrest equipment. The fall protection plan must clearly indicate what kind of protection is required for when persons are working at a fall risk position.
JAN / FEB 2013
h ea lth & safet y Only use safety belts as a fall prevention system. Harnesses are used to protect a person in the case of a fall. They are designed to evenly distribute the force of the fall, so that the least possible injuries are sustained. Users should be trained correctly in the use of safety belts and harnesses and must understand how to effectively use one. Equipment should always be in good condition – free from cuts, tears and defects. Remember: Never use a harness that has been involved in a fall. It will not protect you in the next fall. If the harness is damaged or has been used in a fall, it must be destroyed and thrown away so that another worker does not use it by mistake.
24
Floor covers must be used to cover up holes and gaps in decks and floors. Falling through a hole will result in serious injury. The use of hard, undamaged, wooden boards to cover up holes is a sufficient solution. Remember to fasten the boards to the surface to prevent them moving and exposing the hole. Openings in floors, edges, slabs, hatchways and stairways must be fitted with this protection or barricading and remember to place warning signs in these areas to remind workers of the hazards. In some cases it is required to use a Man Cage for working in an elevated position. You may not use a Man Cage unless it has been approval by the Department of Labour.
All safety belts and harnesses must be identified and entered into an inspection register. The supervisor must ensure that the equipment is inspected on a regular basis and the findings recorded in the register.
For more information on Fall Protection Safety and other related safety topics visit www.safebuild.co.za.
Safety nets are also a great system for fall protection and should be used in conjunction with harnesses or where other types of fall protection mentioned could not be applied sufficiently. Safety nets must be regularly inspected and should be installed as close below the workers as possible. This will ensure the worker only falls a short distance if there is an accident.

Major steel supplier targets conceptual phase of projects Building on the momentum gathered by steel manufacturer and distributor BSi Steel’s Bulk Sales Division, the company has recently launched a Projects Division aimed at the conceptual stages of a project.
B
Si Steel Projects Division Trader, Richard Oelofse, explains that the Projects Division aims to actively seek out and work closely with decision makers and project engineers from the conceptual phases of a project to completion. “The drive behind the launch of the division is for BSi Steel to become a service provider and partner to clients throughout the progression of a project, even before the need for steel arises at the construction phase. Customers will be dealing with one supplier from start to finish, thereby allowing for savings in money and time,” explains Oelofse. Even though BSi Steel already has existing Exports and African Divisions, involvement from the conceptual stage of a project, which BSi Steel has established to be a critical element in the supply of steel to a project, was lacking. Oelofse says that the new Projects Division fills this gap.

BSi Steel Bulk Sales Chief Executive, Craig Parry.
The Projects Division is leveraging BSi Steel’s already strong presence in Africa through its various branches and in-country employees. The Project Division’s footprint will stretch across South Africa and Sub-Saharan Africa, with a strong focus on projects in Madagascar, Mozambique, Namibia, Zambia and the Democratic Republic of Congo. “With longstanding relationships with many of the main players in various industries already set up through BSi Steel, we are optimistic about the success of the division. Currently, we are looking at specifically targeting solar and wind energy projects in South Africa. We are also investigating projects in Africa involving dam wall construction for hydropower and road infrastructure projects,” explains Oelofse.
About BSi Steel BSi Steel was listed in 2007, and raised R 100-million during its public offering. This resulted in the company being able to explore new markets, both in South Africa and on the African continent. It also enabled BSi Steel to establish its main distribution and processing facility in Klipriver, Gauteng. With this modern facility and the established branch network in South Africa, Zambia, Mozambique, DRC, Ghana and Zimbabwe, BSi Steel has managed to increase its market share significantly over the past four years.

Football for Hope Eco-Insulation proudly assists Architecture for Humanity
Eco-Insulation KZN/Northern Free State (Ross Dunbar and team)
F
ootball for Hope is an outreach initiative of FIFA™ given impetus by its ‘20 Centres for 2010’ programme that began in South Africa as the official campaign of the FIFA World Cup™ 2010. In South Africa, the programme was readily supported by Architecture for Humanity, an international nonprofit architectural organisation involving the creation of a more sustainable future through design. Architecture for Humanity identify and pinpoint positive solutions for change in communities that are underprivileged and vulnerable to the effects of climate change. Local architects worldwide provide pro bono services to projects in their regions, including certain public-spirited professionals in South Africa. The centres here are operated by Grassroot Soccer, an NGO that along with Love Life, promotes Aids awareness through the medium of football. South African architects associated with Architecture for Humanity, including Cape Town-based George Kinuthia, partner with built environment suppliers to provide pro bono design, project management and material support for projects in deserving areas. Hence cellulose fibre ceiling insulation supplier and installer, Eco-Insulation Cellulose Fibre Ceiling Insulation, became involved in supporting five Football for Hope centres around South Africa.
28
At the most recently completed project, KZN Eco-Insulation installer, Ross Dunbar, donated product and services to the construction of the Football for Hope Centre, at Qua Qua in the North-East Freestate, close to Harrismith. A total of 100m2 of Eco-Insulation was pumped into the pitched roof section above the ceiling. According to Kinuthia, the Eco-Insulation team “was very professional and engaging in the whole process from arrival, assessing the scope, advising how they plan to execute, execution and satisfactory completion of the same.” Dunbar is part of a growing network of Eco-Insulation approved installers nation-wide, who support sustainable building practice via the supply of SABS-approved, fire-rated recycled cellulose, thermal and acoustic insulation derived from newsprint waste recycling streams. Eco-Insulation might be made from recycled newsprint, but this belies the high-tech and robust nature of its performance. The product is both SABS-approved and fire-rated, meaning no spread of fire in the roof where the product is installed. Professionally installed, it is rapidly and efficiently pumped into place in the roof, cavity wall or even under the floor.
JAN / FEB 2013
in s u l ati o n
Due to the fact that it is professionally installed and hence installed correctly, it meets all the specifications prescribed by the Thermal Insulation Association of South Africa (TIASA), and SANS. Eco-Insulation's GM, Richard Ellis, tells us that the product is ideal for the roof. “Rats, mice and other household pests find it very difficult to nest inside a roof that contains Eco-Insulation – in fact they are repelled by it. So this makes the product an ideal solution for rural areas where such animals naturally reside and where little prospect for maintenance exists!” According to Cameron Sinclair, Executive Director for Architecture for Humanity, more than two million people have lived, worked, gathered and healed in buildings designed by Architecture for Humanity staff, design fellows and volunteers to date.
“In 2011, we completed clinics, schools and community centres for social change. By 2012, we were managing nearly fifty projects in dozens of countries that include civic art, libraries, regional planning and an economic development and reconstruction centre.”

Coverland Dry Ridge System Cracked mortar along ridge and hip lines are a common sight on South African roofs, not to mention the unsightly repair work. The innovative Coverland Dry Ridge System replaces traditional ridge and hip line applications.
T
he system involves an easy roll and clip installation on the ridge and hip line of the roof that allows for optimum air circulation and maximum protection against the elements. No more messy mortar that cracks and leaks!
The Coverland Dry Ridge System has the following benefits: • Storm- and weather-proof. • Ventilation prevents damp and mould, contributing to your health and wellbeing. (A well-ventilated roof prevents damp and mould, which rots the timber trusses and damages the roof. Also, according to the WHO, the prevalence of damp and mould increases people’s susceptibility to asthma and allergies.) • Material and labour cost saving: installed in one third of the time of traditional mortar ridge applications. • No cracking or leaking usually attributed to mortar applications. • Maintenance free. • Quick, easy installation.

Ridge Clip. The system consists of a Coverland Compact Roll, Ridge Trees, Kro Clips and Ridge Clips. Key to the efficacy of the Dry Ridge System is Coverland Compact Roll. This waterproof, dry-fix roofing solution replaces traditional mortar methods and – due to its unique, breathable composition – provides a well-ventilated roof that prevents damp and mould, and ensures the circulation of fresh air in your roof’s interior.
Although more expensive than traditional mortar fixing, the Coverland Dry Ridge System is a long term solution that is easy to install, aesthetically pleasing and, best of all, maintenance free. For more information visit www.coverland.co.za or send an e-mail to info.za@monier.com
Compact Roll can be stretched to fit any roof profile and its unique, integrated waterproofing and ventilation features, when combined with the Ridge Tree, provide optimum airflow and 100% leak-free performance. The unique, patented 4-Layer Assembly® of the Compact Roll ensures: • Sustainable sealing (butyl-supported aluminium compound) • High tearing strength (very resistant PET Polyisobutylene compound) • Maximum waterproofing properties, while allowing ventilation (ventilating holes are covered by a highperformance fleece) • Extreme adhesion, due to the highly effective CH-bond butyl glue. Ridge Trees allow an optimal alignment of the ridge and hip battens. Attached under the topmost batten and onto the counter batten or rafter, the ridge and hip tree is used to fix the ridge runner. The steel is strong yet pliable, while the holes allow for easy fixing to the ridge batten using screws.
Kro Clip installation.
Made from corrosion-resistant stainless spring steel, the Kro Clips fix cut tiles to the hip structure without the need for drilling into the concrete tile. Supplied with a 30cm long corrosion-resistant binding wire, which is fixed from the clip to the nail in the support batten (hip batten or hip rafter), it is easy to install. Only nails and a hammer are required. The ridge clips are made from stove-enamelled aluminium and are used to fasten ridge tiles to the ridge and hip batten once the Compact Roll has been applied.

Regulating the manufacturing and erection of timber roof structures Roof trusses come in all shapes and sizes to suit every roof design, and constitute the large timber members that comprise the framework of the roof, providing a structural base for the installation of the roof covering material.
T
he main members of the roof structure are referred to as the rafters, tie beams and the webs. Timber trusses are either prefabricated or manufactured on site by a specialist carpenter. Site manufactured roof trusses are bound to comply with the deemed-to-satisfy requirements of SANS 10400 (Part L), which does not cater for complex roofing solutions.The architect’s design of the roof will determine the truss design and depends on factors such as the intended pitch of the roof, configuration of the house and whether or not the internal walls are load-bearing. When the builder has erected the scaffolding, the roof trusses are hauled up onto the top of the walls and are then firmly fixed onto wall plates with metal anchors/ties that have been pre-built into the brickwork.
Role of the Institute for Timber Construction The Institute for Timber Construction South Africa (ITC-SA) is an industry body geared to inform and educate building contractors about this integral component of the roofing structure, while equipping homeowners with information that can affect the building of their homes.
32
The ITC-SA conducts ongoing research and development to ensure that the design, manufacture and erection of prefabricated nail-plated timber trusses are carried out in accordance with set industry standards. To enable this, the ITC-SA liaises closely with the South African Bureau of Standards (SABS), the National Home Builder Registration Council, the National Regulator for Compulsory Specifications, the South African Timber Auditing Services (SATAS), the Engineering Council of South Africa (ECSA) and the four leading nail plate system providers, Mitek Industries, Alpine Automation SA, and Multinail Africa and International Truss Systems, which supply fabricators with engineering software for the design and manufacturing of rationally designed timber roof structures. On the operational front, the ITC-SA has established regional branches in the Western Cape, South/Eastern Cape, OFS, Polokwane, Mpumalanga and KwaZulu-Natal, all of which are operating successfully.
JAN / FEB 2013
tr u s s e s
Erectors: Bracing and connection rules for timber roof structures are researched and updated. Awareness is created through seminars and presentations to disseminate information and amendments on specifications and regulations to industry role players and to educate erectors where possible. The Institute has developed two volumes for the erection of timber roof structures. The Roof Erectors Handbook Volumes One and Two have been revised and updated to include changes in SANS 10243, and are available from the ITC-SA offices. The ITC-SA co-ordinates an infrastructure of professional roof inspectors, who operate under delegated authority from the ITC-SA Accredited Engineers. These accredited inspectors are able to inspect the timber roof structure for compliance with the National Building Regulations, so that homeowners can obtain an occupancy certificate from the local authority.
To regulate the application of structural timber, the ITC-SA is involved in the following activities: • Acquiring the necessary skills in the field of timber engineering from international sources, or through research, so as to develop reliable codes of practice. • Research and updating of bracing and connection rules through the Timber Engineering Advisory Committee, and the publication of erectors’ and designers’ handbooks to disseminate information to the market place. • Arranging awareness seminars on the erection and bracing procedures for engineers, architects, clerks of works, building inspectors, builders and carpenters. • Encouraging the removal of barriers for the acceptance of timber structures by local authorities, government agencies, lending institutions and professional groups. • Working to establish the availability of appropriate grades, sizes and quality timber that will ensure safe and economical timber structures. • Providing the expertise to answer technical enquiries effectively and to investigate problem structures impartially, or to act on complaints from customers or fabricators in an unbiased and fair manner.
Engineers: ITC-SA acknowledges engineers with extensive experience and proven competence in timber engineering by accepting them as Accredited Engineer Members. To ensure full compliance with all the provisions of the Building Standards Act and National Building Regulations, these engineers may inspect and sign off rationally designed and erected timber roof structures.
Training: The ITC-SA constantly evaluates the performance and skills of its members, and to enhance industry capabilities, presents courses and provides information that will assist members and non-members in adhering to standards.
Membership benefits: The ITC-SA and its members are key role players in the timber roof truss industry. The Institute provides an opportunity for everyone associated with it to participate and shape the future of the industry through knowledge and expertise, so as to continuously update and review regulations and specifications. The ITC-SA believes in an industry working in unison to promote a common interest and which will produce results more effectively than individuals working separately. Also, a unified Institute has more authority than individuals, and can ensure that the industry follows and complies with the norms and standards that have been developed in consultation with industry stakeholders and which will allow for proper regulation.

Fabricators: To ensure compliance with industry standards, licensed fabricators are audited for the awarding of a Certificate of Competence. This certificate confirms competence and quality in the manufacturing and supply of pre-fabricated nail plated timber trusses. The ITC-SA also runs courses for estimators and designers, and strives to continuously upgrade the quality and competency of personnel in truss plants.

Scaffolding Safety A recent scaffolding accident, which left one person dead and 19 injured after heavy winds overturned the structure, has highlighted the need for strict adherence to standards regarding correct scaffolding design and construction.
D
eon Bester, Occupational Health and Safety Manager at the Master Builders Association of the Western Cape, shares his expert advice on how to prevent accidents like this from happening in future: The design and construction of any steel tubular scaffold must comply with the South African National Standards (SANS) Code 10085. This contains requirements for design, maintenance, inspection, safety precautions and usage. To erect scaffolding that conforms to the standards contained within the Code, there are a few fundamental things that need to be taken into consideration. These include the condition of the surface on which the scaffold is to be built, the weather conditions to which it will be exposed, the load that will be imposed upon it and the wind pressure to which it could be subjected. Scaffolding is divided into four specific categories, based on the weight it is able to bear safely per m². The type of scaffolding required must be determined before a design is prepared in order to ensure that it can safely withstand the load it will hold as well as both vertical and horizontal wind pressure. Any scaffolding that does not fall into one of these categories must be designed by a scaffold designer or professional engineer. All materials to be used in the construction of scaffolding must be inspected by a supervisor before use to determine their suitability and ensure that they conform to the required standards. The area on which the structure will be built must also be Deon Bester Occupational Health and Safety Manager for the Master Builders inspected. Supervisors are appointed by the Association of the Western Cape, employer and must possess the necessary qualifications from an accredited training provider and approved by the South African Qualifications If the scaffolding is enclosed with sheeting, shade netting or Authority (SAQA). He or she must also comply with the legal advertising banners, this must be investigated and approved construction regulations as well as those contained in the before use since it could affect wind loading. The scaffolding SANS Code. needs to be checked once a week, especially after inclement weather or alterations, with the details of these inspections Scaffold structures may only be constructed by trained, recorded in a register. competent scaffold erectors under the direction of a supervisor. Once the structure has been built, it must be inspected and declared fit for use. All scaffold erectors must have undergone the requisite 18 months of classroom and practical training. No untrained people are allowed to alter or remove items from existing safe scaffold structures as the removal of one component would render the entire scaffold structure unsafe and unfit for use.
34
All scaffolding structures must be clearly marked with signage that complies with the requirements of the SANS1186-1 Code to indicate whether it is safe for use and every employee on a construction site must be trained to recognise and obey these signs. “A scaffold structure that is properly planned and executed, with a variety of variables taken into account, can ensure the safety of both employees and the public,” concludes Bester.

Solar power solutions could lighten business burden South Africa’s electricity tariffs used to be among the lowest in the world, but if the national power utility Eskom is granted approval for its request to implement a 16% electricity price hike, the country’s power would soon be among the most expensive in the world.
I
n October, the parastatal applied for permission to increase the electricity tariff by 16% annually over five years, which will amount to R1 trillion. If the National Energy Regulator of South Africa (Nersa) agrees to it, increases would kick in for Eskom customers from April 2013, and from July 2013 for customers who have their electricity supplied via municipalities. South Africans have already been subject to tariff hikes from Eskom, and are reportedly paying 142% more than they were in June 2006. Should Nersa accept Eskom’s new request, economists have calculated that the cumulative effect of the tariff increases between 2002 and June 2017 would amount to a 580% increase. “These additional increases would be the tipping point that will cause many local businesses to go under. Such sky high prices will most certainly also be a deterring factor that will prevent international companies from investing in South Africa,” says Trevor de Vries, Managing Director of AEG Power Solutions, the local division of the global solar giant. “To add even further insult to injury, Eskom is proposing these hikes to cover its operational costs at its rapidly ageing power plants, and to fund the construction and completion of new coal-fired power stations – which are notoriously noxious polluters and a leading cause of smog, soot, acid rain, and other toxins that are harmful to health and the environment.”
A few years ago, renewable power was prohibitively expensive, but advances in technology have reduced the production costs of solar power in particular. Now, with these increases on the horizon, solar is even more cost-efficient comparative to coalpowered energy. “The question is at which point we reach parity in the cost of solar power versus the cost of traditional power. At that point, it makes infinitely more sense to invest in solar,” he says. “We’re almost there, as the continuing rate hikes by Eskom push the price of coal-powered electricity close to the price of solar-powered electricity. And with the Demand Management programme, where Eskom provides rebates for companies that save energy, there’s no other way to look at it but that the way of the future is renewable energy – and solar in particular.” De Vries says that it is cost-effective, not just in terms of savings in the long term, but because consumers can actually generate income from it too. “Not only do consumers of solar power take some of the load off Eskom’s national grid – which is already under strain to keep up with demand – but the excess solar power they do not use can be sold back to the utility. Being able to access power at its source and provide the energy required to power industry is a no-brainer. With the abundance of sunshine in South Africa, it provides a very good business proposition.”
The time is therefore ripe for South Africans – especially business owners – to seriously consider switching to alternative sources of power, such as solar, advises de Vries.

WoodEX for Africa 2013 launched to the industry WoodEX for Africa 2013, Africa’s leading timber trade exhibition being held at Gallagher Convention Centre from 21 to 23 March 2013, was recently launched to the timber industry at a function held at Gallagher Convention Centre.
S
peaking at the event, WoodEX Exhibition Manager Lynn Chamier said the international interest in WoodEX has grown tremendously since the inaugural exhibition earlier this year, and agents in Europe and China are actively marketing the show. “Bookings for exhibition space are already more than 50 per cent up compared to the same time last year, and we are receiving enquiries daily. We are looking forward to an excellent event in 2013.”
Another first at WoodEX for Africa 2013 are Timber Talks, a number of short seminars which will provide a dynamic and interactive learning experience to visitors at the exhibition. Timber Talks will offer visitors the opportunity to share knowledge and stay up to date with the latest developments in the industry.
Highlights at WoodEX for Africa 2013
New for WoodEX for Africa 2013 A first at WoodEX for Africa 2013 will be the introduction of The Hub, an area where ‘first-time’ exhibitors will be able to book 2 x 2 m² stands in a specific area called The Hub. “This area, which is an open space with a cocktail table, chairs, brochure stand and pull-up banner included in the price, is ideal for smaller companies who would like to exhibit for the first time, as it allows them the chance to showcase their products and services at a reduced cost,” says Chamier. Only eight of these spaces are available at WoodEX.
38
Highlights on the 2013 WoodEX programme include the event’s Timber Games which will be broadcast on Supersport. During these thrilling games South Africa’s most skilled chainsaw operators and wood carvers will showcase their craft in speed cutting and carving competitions. Another highlight on the programme will be the demonstrations by celebrated DIY guru and television personality, Riaan Garforth-Venter, better known as ‘Die Nutsman.’ Riaan, who is synonymous with creative ideas, DIY, eco-tips, conservation and beautiful homes, will share his passion for wood by demonstrating various techniques, and he will also use this platform to film one of his ‘Nutsman’ television programmes.
