“ Is your builder ..... a Master Builder?" Find a Builder Master Builders South Africa is the leading national representative body in the building and construction industry in South Africa. It is a voluntary membership based organisation whose primary role is to promote the viewpoints and interests of the industry, to promote the highest quality and standards through excellence in service to our members, engaging government and legislative bodies on national policies that affect the industry, for the purpose of creating a sustainable building industry in South Africa. Master Builders South Africa is a Federation of registered employers' organisations which represent contractors and employers operating in the building and construction sectors. The Federation is regulated in terms of Section 107 of the Labour Relations Act, Act 66 of 1995. Master Builders South Africa represents its members on national bodies and lobbies national government on legislative and other policy issues. It also provides a range of services to its members which encompass training needs, legal services, labour relations, building codes and standards, and economics which affect the building industry. Is your builder ..... a Master Builder? If you want to find a builder, whether commercial or domestic, large or small, click on the logo and look for the office in your province or region to find information on the MBAs' members. National Federation for Building Trade Employers Master Builders South Africa was founded as the National Federation for Building Trade Employers (NFBTE) in 1904. Over the past 108 years, MBSA has survived and flourished and still plays a meaningful role in today’s fast-track world. The Federation’s initial aims were to unite the contractors of the day to gain better bargaining power with government authorities and to negotiate with trade unions. BIFSA born out of the NFBTE The NFBTE itself faced change and there was a growing sense among members of the national organisation that its name was no longer representative of the building industry it now represented. Moreover, the name was

cumbersome and did not clearly identify it as a Federation for builders. Much to the chagrin of some of the longest-serving members of the Federation, the 1967 Congress agreed - after a full year of deliberation - to change the name of the National Federation of Building Trades Employers to the Building Industries Federation (South Africa) and BIFSA was born.

Master Builders South Africa When BIFSA celebrated its centenary at a gala dinner held at the International Convention Centre in Durban on 23 March 2004, 100 years to the day that the NFBTE was formed, it was a radically changed organisation not just in name but in structure as well. Master Builders South Africa was the new name for the organisation, chosen because it clearly reflected the fact that it was a national representative body for all Master Builders Associations around the country.

Association Archaeologists (ASAPA) The Association for Southern African Professional Archaeologists (ASAPA) is a non-profit, non-governmental organisation that exists for the purpose of establishing, maintaining and promoting archaeology in southern Africa. Archaeology is now recognised as an important component of our heritage, but that heritage is increasingly threatened by urban development. Professional archaeologists have a crucial role to play in studying, preserving and promoting our archaeological heritage. The origins of ASAPA lie with the Southern African Association of Archaeologists (Sa3), which was established in 1970 to encourage the training of archaeologists and to promote archaeological heritage in southern Africa. In response to the changing status of archaeology and the increasing professionalisation of its practitioners, the membership of SA3 decided to become a formal professional body in 2004. As a professional body, ASAPA is committed to the development of archaeological research, management (including conservation, curation, archaeotourism and restoration), outreach and the exchange of archaeological expertise and information, in and beyond southern Africa. The International Association for Impact Assessment South Africa (IAIA sa) "Impact assessment, simply defined, is the process of identifying the future consequences of a current or proposed action." The International Association for Impact Assessment (IAIA), organized in 1980 to bring together researchers, practitioners, and users of various types of impact assessment from all parts of the world. IAIA involves people from many disciplines and professions. Members include corporate planners and managers, public interest advocates, government planners and administrators, private consultants and policy analysts, university and college teachers and their students. One of the unique features of IAIA is the mix of professions represented, which provides outstanding opportunities for interchange: to advance the state of the art and science of impact assessment in applications ranging from local to global to develop international and local capability to anticipate, plan and manage the consequences of

development to enhance the quality of life for all. Regional conferences are organized to make information exchange and networking opportunities available to those who might not be able to attend the international conferences, as well as to focus attention to specific issues. Training programs are held regularly in conjunction with IAIA international conferences. These range from one day to one week in duration and deal with a variety of impact assessment issues. The quarterly journal, Impact Assessment and Project Appraisal (IAPA), contains a variety of peer-reviewed research articles, professional practice ideas, and book reviews of recently published titles. IAPA provides a one-source link to the latest ideas in the wide-ranging field of impact assessment. South Africa is the sixth country in the world (after USA, Australia, Brazil, and Canada) to form a local IAIA affiliate. South Africans attending the annual congress of IAIA in Washington DC in August 1992 formed a steering committee to launch the IAIAsa later that year. The IAIA affiliate was formally recognised by the parent body at its mid-year meeting in Mexico in February 1993. The primary objective of IAIAsa is to create a "home" for those people who wish to exchange information on, or learn more about, impact assessment. South Africa has received international acclaim for its Integrated Environmental Management procedure and for the high quality Environmental Impact Assessments undertaken in this country. South African Council for the Landscape Architectural Profession (SACLAP) The South African Council for the Landscape Architectural Profession (SACLAP) was established as a statutory council in terms of Section 2 of the South African Council for the Landscape Architectural Profession Act – Act 45 of 2000 (referred to as The Act hereafter).

Pretoria Institute for Architecture (PIA) The Pretoria Institute for Architecture (PIA) is a Voluntary Association recognised by the South African Council for the Architectural Profession (SACAP), and is a ‘Regional Institute’ of the South African Institute of Architects (SAIA). The PIA has origins in the Pretoria Architectural Society which was founded in 1945. The PIA was created to serve the interests of architects in the Pretoria area, to further good Architecture and to care for the Architectural heritage unique to Pretoria. The Transvaal Provincial Institute of Architects, having existed for the better part of a century, ceased to exist in the early 1990's and the South African Institute of Architects was established. This was the opportunity for the local architectural societies to become regional institutes in their own right. The Pretoria Architectural Society became the new Pretoria Institute of Architects. However, the constitution and subsequently the name changed to acknowledge and provide for other forms of membership, such as Technologists, Artists, Historians and Friends. Our name is now the Pretoria Institute for Architecture. While concentrating on the day to day aspects of running a practice, it also takes into account inter alia the dissemination of information, liaison with the local authorities, the promotion of the profession, heritage, education and matters pertaining to the habitat. These functions are carried out through committee structures which in turn are reflected in the constitution of the PIA. Events typically include bi-annual exhibitions, professionally arranged publications, commitment to, organising and facilitating of congresses, CPD events and expert advice to members. Friday breakfasts, luncheons, talks at the two universities in Pretoria, biennial awards and other social events more often than not carry a professional or technical component, the combination of which being well received by the membership, accounting for the good attendance at all events. Members of the PIA have been called to offer professional service at various universities throughout the country and to serve on various national and international professional bodies, giving credence to its mission and value to its members.

The Staff Residence at Rob Ferreira Hospital was awarded to Consultium Architects after the successful completion of a master plan done for the entire complex in 2009. This building will be a true landmark in the Nelspruit CBD, as it will stand a proud 13 stories and will be the highest building ever constructed in this region. The building consists of 147 accommodation units for Doctors and supporting staff with two levels of basement parking. Ground floor is allocated to meeting facilities, a coffee shop and open space for social activities, towered by two large multi volume atriums creating vibrant atmospheres. This building was designed to have a modern appearance within the approved budget and at the same time serve as a counterpart and link between the existing

residence and the new resource centre, both constructed concurrently. The building being the highest ever constructed in the Nelspruit CBD, had various town planning challenges that needed to be overcome. The professional team worked closely with local town planners, fire and traffic engineers. Due to the concentrated housing of people, the design had to incorporate the upgrade of the existing entrance, additional parking bays required meant that the entire hospital’s site development needed to be re-considered. Building works started in January 2012 and the project was scheduled for 21 months, no serious changes were made on the project after it was handed over to the main contractor. A few design changes were implemented during construction, but this is common on any project, and more

so on a project of this scale and value. This is one of the bigger projects in scale and value that Consultium Architects has undertaken in the past couple of years. What makes this project unique is the fact that we can record that we have successfully designed and administered one of the highest structures built in Nelspruit to date.

Supplement Modeling & Analysis Solve Centrifugal Pump Reliability Problems Modifying multistage, split case, centrifugal pumps reduces joint deterioration. As the use of variable speed drives with centrifugal pumps increases, pump users are more commonly operating pumps at higher speeds than their original design intended. Higher speeds correspond directly with increases in head and capacity. These higher pressures and a lack of asbestos gasket material can cause sealing reliability issues for some older split case pumps. Modern three-dimensional (3-D) solid modeling and finite element analysis (FEA) can assist centrifugal pump engineers with incorporating design changes that solve these reliability issues. Case Study Steel mills use high-energy, multistage split case centrifugal pumps for descaling operations. The design of these pumps is similar to many boiler feed pumps in power plants. In 2008, a rotating equipment repair company investigated some reliability issues on several 4 x 10 12-stage descale pumps for a steel mill in Indiana. The pumps in question were designed to operate at 3,600 rpm with a given flow and pressure. However, because of system requirements in the steel mill, the pumps were operating at 5,400 rpm to produce significantly higher pressure. This increased performance caused heavy washing across the interstage cavities, resulting in internal flow recirculation. The flow recirculation was visible at the pump disassembly and was indicated by the dull finish on the areas surrounding the discharge cavity or tongue of each stage (see Image 1). On average, the flow recirculation caused these pumps to drop below acceptable performance levels after only 2,000 operating hours when they were using a conventional graphite gasket and 5,000 hours when using an asbestos gasket material.

Figure 2. A schematic showing the internal pressure distribution used in the FEA Image 1. The effects of the internal flow recirculation are shown by the dull finish on the areas surrounding the discharge cavity or tongue of each stage. This recirculation causes joint erosion and decreased hydraulic performance. Analysis 1: Baseline To find a solution to this problem, repair engineers turned to solid modeling via laser scanning and FEA to evaluate and analyze design modifications. The first step in the process was to create an identical solid model of the casing for use in the FEA (see Figure 1). This model was then used as a baseline in an initial FEA of the casing.

Figure 3. Baseline FEA results showing large areas of minimal contact pressure between each pump stage

Figure 1. A solid model of the pump casing, derived from laser scanning point cloud data The goal of the FEA was to solve for the contact pressure between the casing halves given the existing internal pressures and bolting forces from the standard casing. The pressure distribution used can be seen in Figure 2.

The results of the baseline FEA revealed large areas of minimal contact pressure, corresponding with the known gasket failure areas (see Figure 3). The medium blue areas were estimated to have a minimum contact pressure of 5,564 psi. The typical gasket material used for this application has a minimum seating pressure of 4,100 psi to achieve the full pressure multiplied by temperature rating.

Analysis 2: Increasing Bolting Pressure with Super Studs With the baseline design established, the engineers tested several additional designs for increasing the horizontal joint contact pressure. The first design modification tested was the use of a super stud. The use of an upgraded material from B7â&#x20AC;&#x201D;such as Grade 8, which has 17 percent greater yield strengthâ&#x20AC;&#x201D;can expand the torque value of the studs, increasing the tensile loading on each stud.

BRT System in Tshwane The City of Tshwane on Wednesday started the construction of South Africa’s latest bus rapid transit (BRT) system in Arcadia, Hatfield. The R2.6-billion Tshwane BRT system, which formed part of the city’s revitalisation project, would comprise three depots and 51 stations on an 80 km route stretching through, besides others, the Pretoria central business district (CBD); Hatfield; Menlyn; Sunnyside; Akasia; Kopanong, in Soshanguve; Mamelodi and Pretoria North. Speaking at the construction site of the Arcadia street station, executive mayor Kgosientso Ramokgopa said that the system would go live in April 2014 with the completion of the first phase of the project.

Johannesburg’s Rea Vaya opened its doors in August 2009 and Cape Town’s MyCiTi network was officially opened in 2011. Rustenburg is also planning a BRT system, with construction scheduled to start this month. The City of Tshwane aimed to operate the bus services along BRT trunk routes every three to five minutes during peak hours, with feeder services at the stations and terminals every 15 minutes to enable greater efficiency and ease of use for passengers. The BRT system would operate between 05:00 and 20:30 from Monday to Saturday, and 07:00 and 19:00 on Sundays and public holidays.

The city said the BRT would provide a “rapid, frequent, high-quality, affordable and convenient” public transport service that would improve urban mobility and integration. “Currently, 66% of peak-hour trips are made using private vehicles, leading to traffic congestion. Many economically deprived areas are entirely dependent on public transport,” he explained. The system would be named through a public voting competition ending on July 31. The proposed names for Tshwane’s BRT system were Maleka, meaning ‘roundabout’, A Re Veng, which means ‘let’s go’, Tsumaya, for ‘go’ and Dumela, which means ‘hello’.

Phase 1 would extend from Akasia to Menlyn, through Sunnyside and Hatfield, while Phase 2 would run from Rainbow Junction to Menlyn, through Pretoria North, the CBD and Hatfield. The mayor noted that the entire system, which was yet to be named, would be operational by October 2015. The BRT system would require about 340 buses, some of which would be powered by gas, at a cost of about R1-billion. Ramokgopa expected over 10 000 jobs to be created during the construction phase, and about 1 000 sustainable jobs once the system was live. These included 529 bus operators and related personnel, 94 employees for the proposed call centre and about 300 workers managing and maintaining the ticketing system. “Tshwane's bus rapid transit system will be integrated in partnership with existing public transport facilities, which will ferry passengers to and from BRT stations, improving efficiencies and impact for residents,” said Ramokgopa. He commented that the system was based on the model used by the Rea Vaya BRT in Johannesburg. The Tshwane system would also implement an ownership model, where current licensed bus and taxi operators on the affected routes would eventually own, operate and manage the BRT.

50% of all CO2 emissions

–

50% of energy consumed

So the built environment can be considered the ‘low hanging fruit’ with regards improving our situation, as any improvements in the way we construct can have a real positive effect on our environment…and some think that timber can play a large role in the solution Comparing Building Materials Concrete, steel and masonry are all great building materials, over that there is no doubt. INTRODUCTION People, in general, respond to wood as if connected to it somehow – it appeals to more than just the visual sense, also to touch and smell. If someone walks into a kitchen with a wooden counter top, or picks up one of my timber light fittings, the fist thing they do is run their hands over it – to feel it’s smoothness; sometimes they will even smell it. You don’t often see that happening with other materials. WHY SHOULD WE BE USING WOOD? Some of you might think of, when thinking of using wood; of deforestation, or of the fact that it may burn? I am going to tell you the other side of the story.

But: – CO2 is one of the direct by-products of the manufacturing process of cement –

Steel is also energy intensive to produce

– Combined steel and concrete account for approx 8% of all greenhouse gas emissions

– in terms of resources we’ve reached the point where current demand exceeds supply, so we’ve started eating into our capital – worst still, the waste we produce is polluting the depleting remaining capital, further reducing the effective balance – we face a potential energy crises This is coupled with expanding economies (albeit slowly at present), causing the need for ever increasing resource extraction, and a growing population, with a housing backlog currently of 2.1 million houses in SA. So the question is; how do we meet, not just the South African, but worldwide need for housing? …without further increasing carbon emissions and depleting resources. What we have is the situation of Housing vs Climate Change. The solution that is being put forward is know as ‘decoupling’ – or achieving growth and prosperity without resource depletion and ever increasing carbon emissions So why should any of this effect what and how we build? The reason quite simply, is because the construction industry and the built environment consume: –

PM November December 2014

close to 50% of all resources globally

PM November December 2014

So, with stats like 70% of the developed worlds populstion live in timber frame homes, why is the percentage of timber buildings so small in SA? Possible Reasons – the perception of it as a cheaper & less desirable alternative, perhaps still a result of it’s humble iron clad origins and later cost–effective prefab holiday house, still persists amongst many – though many have attempted, there has been little uptake in the cost effective housing sector – due to inexpensive labour and plentiful clay, brick homes have been the historically preferred choice –

– Clay for bricks is extracted from the earth, ie it is of a finite quantity, and then fired in an energy intensive process And wood? – wood is essentially grown by the energy of the sun, ie. never mind a solar panel or two on your roof, wood is a material born of solar power

We all aware that our planet is basically in a mess: – we are faced with the threat of unprecedented global warming, most of which is now known beyond any doubt to be manmade

advantages – concrete and masonry have, for example, high thermal mass, which is often required in a design – but in general, the more wood we can use to replace other materials, the better for the environment.

– in terms of carbon, when a tree grows, it soaks up carbon dioxide from the air, giving off the oxygen we breathe as a by product – if a tree is left to live out it’s natural lifespan, when it falls over and eventually rots, it gives back only the CO2 that it absorbed – similarly, if it burns it gives back the same amount – if you take wood and build with it, or convert it into furniture or products – that CO2 gets locked away – 1 cubic metre of wood stores 0.9 tonnes of CO2

perceived concerns about timber buildings

Some Common misconceptions Fire ….but won’t it burn down? Having you ever tried making a fire with a match and a log? – Timber is combustible but not flammable, which means it needs a high temperature to get it burning …in the case of a fire – kindling – Large dimension timber is very difficult to get burning, and when it does it chars, which protects the timber and slows down its combustion – Fire engineers can calculate burn & charring rates, and hence the safety factor for varying sizes of timber – The are fire retardants available, for example for timber homes in close proximity – to avoid the spreading of fire – Timber keeps structural integrity for longer than steel when in a fire

– wood is the only major building material that is renewable

– Timber doesn’t change dimension under high temperatures

– and at the end of the lifespan of a building or product – we can burn the wood to use it’s stored (solar) energy, rather than burning oil, coal or gas to obtain the equivalent amount of energy

– Timber’s performance in the case of a fire is very predictable

– wood has an extremely high strength to weight ratio –

so wood …is like natures gift to us!

By using wood instead of conventional materials like concrete, steel and masonry, not only reduces the amount of CO2 emitted, at the rate of 0.9 tonnes of CO2 per cube of material used, but also locks away CO2 for the lifespan of the product, and then if disposed of – makes its stored energy available. That’s not to say we try and use wood for everything, as each type of material has its

– Effective design for fire safety is not about preventing a building from burning if a fire gets out of control – but rather to ensure a safe evacuation of the occupants – ie the structure must remain stable long enough to get everyone out safely. Deforestation ….but you are cutting down all the trees, and there won’t be any left – that can’t be good! – as mentioned early, we need to build and we need more housing for a growing population, and wherever we can use wood instead of high carbon emitting, and higher embodied energy nonrenewable materials, we are doing the environment a favour

Supplement – cutting the wrong trees and transporting timber halfway around the world is not sustainable, but utilising local timber from managed plantations is perfectly sustainable – wood is a renewable resource, for every tree harvested another can be planted. SAFCOL, one of SA’s large forestry companies, are currently planting more than they are harvesting – SA has more than enough SA Pine to meet current housing needs, and some of our forest areas are underplanted, so if / when demand grows planting can be increased On renewability, the Canadian Architect, Michael Green, who is developing systems for building multi-story high rise timber buildings, has calculated that; to grow the equivalent of anough wood for a twenty storey building, taking into account all of the forest areas of the US, will take effectively only 13 minutes Durability …how long will my home last? – there are timber homes and buildings which have been standing for 100’s of years – preservative treatments can prelong the lifespan of timber indefinitely. I mentioned insects with a taste for timber earlier. The reality is that wood is food for some, particularly softwoods – so it must be treated Maintenance In trying to better understand attitudes towards timber homes, given the clear advantages and consistently small uptake, I at the end of last year, along with Timber IQ magazine, did a Timber Building Poll. We had just short of 120 respondents, of which 38% had previously or currently still, lived in a timber home. What was most interesting to me was how the responses of those who had, and hadn’t actually lived in timber homes, compared on average for the same questions. When asked to rate timber homes compared to brick, where an answer of 1 is much less, and a 5 far superior, in favor of timber, for the requirement of maintenance, the average scores were as follows: – Maintenance requirements: People having lived in timber homes 2.87 – Maintenance requirements: Average 2.70

ADVANTAGES OF BUILDING A TIMBER HOME I’ve discussed the advantages of using timber from an environmental point of view, but are the advantages of building a timber home; for the client, the architect or designer, and the builder? For the Client: Insulation – and therefore energy costs. Perhaps not yet such a huge issue, but with a potential electricity hike of around 16% for the next 5 years at this stage, it soon will be Natural Home – many clients chose to build a timber home because they want a more natural home, that better fits into it’s environment – something that feels good. Perhaps they feel that connection to wood. The same applies to beach resorts, and lodges in nature reserves Ease of construction and time to construct – it takes significantly less time to build a timber home than a similar brick & mortar home. It’s also easier to alter or add on to at a later stage – and a lot less messy. Difficult & Sensitive sites – due to using relatively lightweight materials, timber homes are ideal for difficult to access sites – where getting timber there is pretty easy compared to bricks. For sensitive sites timber construction also allows one to nestle right in between the existing vegetation with minimum disturbance. There are also cost savings on steeps sites, by using suspended floor structures Higher floor area to building area ratio – as the walls are a lot narrow than for masonry construction, in the case of typical timber frame 150mm to around 300mm for a plastered cavity brick wall, you get an extra sq.m of floor area for every 7 RM of external wall – which can also be valuable on small sites. And should be considered when comparing square meter rates For the Architect / designer: Contemporary – driven by technology everything around us is advancing in leaps and bounds. Think cellphones, tablets cars. Timber, along with other new lightweight building systems, allows us to be part of that technological revolution – rather than still building the way we were in the pre digital age. Technological advances in design software and digital fabrication technologies are now to allowing timber to be cut and fashioned to any shape you desire. Versatility – So thanks to the extreme versatility of timber, your timber home could be anything from a humble log cabin, to a grand Cape Cod style beach house, a sleek glazed all round clad post & beam house, or a digitally crafted open plan contemporary house with a freeform double curved roof

Building Regulations – Timber homes are included in the South African National Building Regulations standards, in SANS 10082, Timber Buildings. When built to these standards they also automatically achieve the standard required for registration with the National Home Builder Registration Council (NHBRC). They are also easily designed to meet the requirements of the new Energy Efficiency regulations SANS 10400 Part XA. For the Builder: Passion – speak to any specialist timber builder and you are likely to find someone with a passion for their craft and for working with wood. Who would you rather have building your house? Precision & neatness– building with timber is a precise form of construction. Everything needs to be just right to work. For a builder and all involved it’s easier to monitor and see that everything is working according to plan. CONCLUSION I hope I have shown you enough of the advantages of building with timber, to give it some though as an option when planning your next project. From our side, along with the ITFB, there is a continuous drive to increase awareness of the benefits and to promote timber frame as a building method. With SAFCOL, whom I consult to occasionally, there has been a drive over the last few years to change perceptions of timber buildings by building good quality timber frame school classrooms, crèches and other buildings as part of their Social Enterprise Development program. There is also currently a drive to get government departments to consider timber buildings as an option, currently with a view to timber libraries and schools – so we might see that coming on line in the next while – all of which will help promote the acceptability of timber buildings. From a consumers point of view I think we should few building materials the same way we view our food – instead of extracting and manufacturing – lets think about growing it! Nature has, after all, provided us with an option we seem to have forgotten about, a perfect building material that we can grow, harvest, regrow and use in perpetuity.

So, not only was the maintenance of timber homes not seen as higher than a brick homes on average, but is was even less of a concern to people that had lived in timber homes. In reality though, the maintenance of a timber home can vary greatly depending on the type of timber building; – a timber clad timber home will require regular re-sealing – every couple of years, though this is a relatively low skill and simple task – a fibre cement clad timber frame home should require less maintenance than a plastered brick home
