Investing in Africa’s power needs
WRITERS Irene Kabuzire, Elaine Young, Emmanuel Onsomu, Dominic Uys, Lindsay Wagner
It is universally recognized that Africa has a huge demand for energy and this coupled with its poor energy infrastructure make it ripe for expansion and development.
WEB / GRAPHIC DESIGN Augustine Ombwa O. Frankline May
Report s in the past indicate that in several countries in Africa such as Congo and Rwanda over 80% of the population do not have access to electricity and other countries are not faring any better.
ADVERTISING EXECUTIVES Kenya Frances Lagoussis (Mombasa), Denis Ondeyo, Trizah Njoroge, Alvan Wamae
Access to electricity is undoubtedly a key pillar for sustainable economic growth and development . One only needs to see how sleepy towns are transformed almost overnight into bustling centers with thriving cottage industries when electricity is provided.
South Africa: Kevin Schorr ,Tabitha Muthoni, Winnie Sentabire, Prince Moyo, Linda Mangwiro, Angeline Ntobeng
Industries also fare better and become more competitive especially when power is cheap or at the very least competitive.
Uganda: Penny Komugisha, Betty Nabakooza Botswana: Dickson Manyudza, Gerald Mazikana
Recent trends towards investing in energy production are therefore encouraging but more will need to be done in order to leapfrog forward and ensure Africa’s growth is not stunted

Kenya Signs US$2.6bn Deal to Build Modern Railway Line Kenya has signed a deal worth US$2.6 billion with a Chinese construction company to build a new standard gauge railway line between Mombasa and Nairobi. China Roads and Bridges Company signed a commercial contract with the Kenya Railways Corporation, under an agreement that commits the state corporation to deal only with the Chinese company. The new railway line, which will be completed in five years, will carry freight trains at speeds of up to 80km/h and passenger trains at up to 120km/h. The viability of the railway line that will be built according to the Chinese railway designs is based on the assumption that it will be part of a seamless system linking Kenya and Uganda as well serving landlocked Burundi and Rwanda. The new deal comes at a time when dozens of Chinese companies are aggressively chasing deals and pitching to negotiate concessional financing on behalf of Kenyan institutions implementing ambitious infrastructural projects.
The new railway line to be completed in five years will carry freight trains at speeds of up to 80km/h and passenger trains at up to 120km/h.
China to Build Cape Coast Stadium Free-ofCharge President John Dramani Mahama has stated that the financial component and design of the Cape Coast Stadium and the Kotokuraba Market are ready and awaiting his signature for the projects to commence. The President revealed to a delighted crowd in Cape Coast that the Chinese government would, however, build the Cape Coast Stadium free-of-charge. He added that it is a grant from the Chinese government and that the Chinese government is building it as a gift to the people of Ghana in memory of President John Evans Atta Mills. Addressing the chiefs and people of Cape Coast, President Mahama said the government was ready to commence two development projects that were very dear to late President Mills: the Kotokuraba Market Project in Cape Coast and the Cape Coast Stadium. President Mahama added that under the late president's tutelage, Ghana brokered the China Development Bank projects, which have already started yielding results and that these projects were going to transform the country and move Ghana's development forward.
The Cape Coast Stadium is to be built in memory of the late President John Evans Atta Mills.

Museveni Inaugurates Bujagali Hydro power station
President Yoweri Museveni has criticized Africa's past leaders and intellectuals for neglecting the energy sector, a crucial tool for social transformation and modernization. Museveni made the remark while commissioning the Bujagali Hydropower project, a 250-megawatt power plant on River Nile. The President said most African countries would now be modern economies if the leaders had invested in power generation. He assured Ugandans that upon completion of the last phase of the Bujagalai project, the country will not experience powers cuts again. The multi-million dollar Bujagali hydropower project adds another 250MW onto the national grid for consumption. Consumers will not experience load-shedding at any time as power deficit has been wiped out, at least for 24 months. The $860m Bujagali hydropower project was commissioned, unit by unit, in response to energy ministryâ&#x20AC;&#x2122;s strategic decision to replace the expensive thermal power generation at the earliest date and minimize load-shedding. Museveni (in beret) moves to switch on the power at Bujagali Hydro power The move was aimed at saving the money that was used to pay the expensive station on 8th October 2012 thermal power operations. The level of subsidy (payment for thermal power) had reached unsustainable levels and the cumulative amount of subsidy paid out was US$ 386.2 million.
OCI/BESIX Joint Venture Awarded US$ 400M Mall of Egypt Contract
Orascom Construction Industries (OCI) has announced that a 50/50 joint venture between BESIX and Orascom Construction, a 100% owned subsidiary of OCI, has been awarded a US$ 400 million contract to construct Majid Al Futtaim Propertiesâ&#x20AC;&#x2122; Mall of Egypt. The mall will be located in the Sixth of October City outside of Cairo. The joint venture has been awarded the project on a lump sum fixed price basis and construction is scheduled for completion in approximately 34 months. Mall of Egypt will be a 162,500 square meter shopping and leisure development that will include an indoor ski park, a 17-screen cinema complex, 380 retail outlets, a Carrefour hypermarket, an outdoor plaza, an amusement park, a car park, and other associated facilities. The ski park, Ski Egypt, will be modeled after the Ski Dubai component in Dubai's Mall of the Emirates, a Majid Al Futtaim Properties development. Peter Walichnowski, Chief Executive Officer of Majid Al Futtaim Properties said they are now in their 20th year of operations and, notably, have been in Egypt for ten of those years.
Gezhouba Group to Build $500m, 1 000 MW Plant
The joint venture has been awarded the project on a lump sum fixed price basis and construction is scheduled for completion in approximately 34 months.
China Gezhouba Group plans to build a $500-million, 1 000 MW thermal plant in Malawi, which suffers from frequent power shortages, the Minister of Energy and Mining has said. Cassim Chilumpha added that Construction of the coal-fired plant, which is expected to cost around $500-million, is scheduled to start next year and will be completed between 2014 and 2015. Malawi's hydro power plants produce a total of about 280 MW per day, compared with rising demand of around 300 MW, which has resulted in daily power cuts costing the country an estimated $215-million per year in lost output.The plant will be built in the central province along a railway line Brazil's Vale is rehabilitating to transport coal from Mozambique via Malawi to the ports at the coast. Part of that coal will be used to fire the plant. In 2010, Malawi had 63 days of power outages, the worst out of 24 subSaharan countries. 8

New International Airport To be Built The Peru government will invest around $460m in a new airport project and has secured land in the town of Chinchero near Cusco for the construction. According to the Peruvian government, the existing Cusco airport in the region is not capable of handling major flights from abroad, and only operates limited daytime flights.The existing airport is constrained by its inner city location surrounded by hills, preventing large aircraft from flying into the facility.Peruvian President Ollanta Humala said that the Cusco region needs a new airport, because the current one is not sufficient. Humala added that the new airport will not only allow more visits by tourists but will also generate more jobs and will permit modernisation and added value for the surrounding communities.Currently, close to 2,500 tourists visit the region each day from all over the world, in the midst of concerns about the impact on the environment and citadel, according to the local authorities. Located 2,500m above sea level, the former citadel of Inca Empire was built in 15th Century. Currently accessible from Cusco, tourists who want to visit can cover the 112km distance via bus or train.

Neopor®(EPS)- Forms Neopor®, an expandable polystyrene (EPS), is BASF's innovative solution to improve insulation in newly built and renovated properties. Neopor® foams are silvery gray in color because BASF integrated graphite within the Neopor® cell structure. The graphite reflects and absorbs radiant heat and significantly improves insulation capacity. Small, round, black — one material, many applications. Neopor® — is composed of small black beads of polystyrene (EPS) granules containing a blowing agent, which makes it expandable. BASF produces this unique material, which is processed by foam manufacturers, into insulating materials for a wide range of applications. These black beads are foamed by converters on conventional EPS machines and processed to silver-grey foam blocks and moulded parts with up to 20 % better insulating performance than conventional EPS. The blocks are then cut to boards of different thicknesses. Website: www.basf.com

ASSOCIATION NEWS & EVENTS
The Construction Industry Federation of Zimbabwe The Construction Industry Federation of Zimbabwe (Cifoz) has called on government to introduce legislation that will make it mandatory for government departments and local companies to give preference to local contractors ahead of their foreign counterparts when they award tenders, in order to save the construction sector from collapse. Former Cifoz president Daniel Garwe says construction firms are struggling to resuscitate operations after the sector nearly collapsed at the height of the country’s political and economic crisis, which ended with the installation of a government of national unity in 2009.Like the rest of the economy, the construction industry is reeling from the effects of a worsening liquidity crisis, which has been compounded by a heavy reliance on expensive short-term loans for capitalisation. Garwe says the interest rates charged on loans by local banks are punitive, sometimes going up to 30% and the loan tenure of 90 days is very short. Further, he says the few players that have managed to return to business use antiquated construction machinery, which deprives them of the ability to compete for tenders against well-financed foreign firms which operate the latest technologies.

WSP Launches Future Cities
KenGen invites Bids for Johnson Tiles South Africa Development of Geothermal plants Celebrates 60th Anniversary
To compete successfully, a city must be sustainable and provide a quality of life that matches all expectations
Kenya is the first African country to drill geothermal power, tapping vast reserves of steam energy in Kenya's Rift Valley.
By 2006, Johnson Tiles became the first and only manufacturer in South Africa with the capability of producing glazed porcelain tiles.
The 21st Century will be defined as the urban age as the growing global population seeks prosperity in towns and cities across the world. As the engines of national economic growth, cities must compete with each other globally as well as within their own countries. To compete successfully, a city must be sustainable and provide a quality of life that matches all expectations. It must have economic vitality, provide social well-being and create an environment where people want to live, work and visit and where businesses can operate profitably.
Kenya's main electricity producer, KenGen, has invited parties to submit bids for the development of 560 MW geothermal power plants.The company said it planned to develop the power plants in phases of 140 MW each at Olkaria within the east African nation's Rift Valley under a joint venture arrangement in which successful bidders would build, and later transfer the facilities back to the firm after 10 to 20 years.
This year marks 60 years since Johnson Tiles was founded in South Africa in 1952. Established in 1901 in the United Kingdom, Johnson Tiles has a proud history rooted in the design and manufacture of high quality wall and floor tiles, and with a presence on five continents; it is one of the largest suppliers of ceramic tiles in the world.
It is against this backdrop that WSP launched Future Cities in South Africa on 11 October 2012. Eric Noir of WSP Green by Design says WSP Future Cities Africa is a service that provides quantified analysis of urban design and infrastructure in sustainability terms; and the delivery of urban solutions for a sustainable future in the natural and built environment. During his presentation, Richard Palmer, WSP’s Specialist in precinct analysis said “2% of the built environment is designed by architects and the informal must be accounted for.
KenGen said the successful bidder or consortium would be the majority shareholder.Kenya is the first African country to drill geothermal power, tapping vast reserves of steam energy in the country's Rift Valley region, which remains geologically active. The country has the potential to produce 7 000 MW and is targeting production of at least 5 000 MW of geothermal power by 2030.
It was in the 1950s that the dream to build a Johnson Tiles plant in South Africa was finally realised when a pilot plant was established in Olifantsfontein. The first kilns laid down were electrical multi-passage Gottignie kilns that fired bisque and glost tiles and had an average output of about 3000m² per week. The Gottignie kilns were later replaced with two biscuit kilns and three glost tunnel kilns. Until 1984 production at the factory was limited to wall tiles.
Although expensive to drill initially, development of cheaper geothermal power means the country will come to rely less on thermal power, prone to the vagaries of high international prices, and rain-fed hydroelectric dams. The cost of energy is a key factor in the east African nation's inflation levels.
The introduction of locally made floor tiles was difficult as local goods were seen as inferior to imported goods. However, because local tiles were more affordable than imported tiles, the demand for them grew, especially in the contracts market. By 2006, Johnson Tiles became the first and only manufacturer in South Africa with the capability of producing glazed porcelain tiles.

Guest Dr. Martin van Veelen President SAICE, FAEO Dr. Van Veelen, President of the South African Institution of Civil Engineering (SAICE), is currently a director at Iliso Consulting in Centurion and an industry veteran with a total of 33 years’ experience in civil engineering, environmental management and project management, mainly in water-related projects.
Dr. Martin van Veelen
This includes extensive experience in water quality, especially water quality management, water quality monitoring and water quality assessment. He gained his extensive experience in numerous fields of engineering, including planning, design, construction and management, as well as in academia. Recently, Dr. Van Veelen was elected as the new president of the Federation of African Engineering Organisations (FAEO). Construction Review magazine had an interview with him and below are the excerpts. How do you feel on your election as president of the Federation of African Engineering Organisations? Being elected as the first President of the Federation of African Engineering Organisations is a significant honour, but at the same time an exciting challenge in that a new organisation has to be made operational. Your vision as president of Federation of African Engineering Organisations? My vision is that the FAEO will ultimately bring together all engineering practitioners in Africa and standardise qualifications and training so that all professionals can practice freely across the continent. The FAEO will actively promote engineering as a profession and build capacity in order to provide the infrastructure that is needed to unlock the full economic potential of Africa.
My vision is that the FAEO will ultimately bring together all engineering practitioners in Africa and standardise qualifications and training so that all professionals can practice freely across the continent. 14
When was SAICE formed, the reasons for forming it and its vision? SAICE was formed in 1903 as a learned society that had the purpose of enhancing the art and science of civil engineering in South Africa. The 2003 centenary celebrations highlighted the importance of civil engineering’s contribution towards socio-economic development in a developing country. The centenary conference had the then president of the RSA, Thabo Mbeki and Minister of Finance, Trevor Manuel, as guests of honour. In his address president Mbeki called civil engineers the Leonardo da Vinci’s of our time. Noteworthy milestones in the development of SAICE? SAICE has over the years contributed greatly to the development of civil engineering in
South Africa by offering courses for continued professional development, organising conferences and producing documents such as the General Conditions of Contract that is widely used in the industry. A significant milestone was when the technologists and technicians amalgamated with SAICE, changing it from an organisation for civil engineers, to an organisation that serves all civil engineering practitioners. How has SAICE benefited members and the civil engineering industry as a whole? Over the last number of years SAICE has grown to an organisation of some 9 000 members. SAICE has been able to play a significant role in mobilising retired engineers to the local authorities in order to strengthen the capacity of those authorities to implement MIG (Municipal Infrastructure Grant) funded projects. This has benefitted not only those companies that were involved in the design and construction, but also brought some relief to the beneficiary communities. Unfortunately this project was terminated by the South African Government about two years ago. Many of SAICE’s members are also members of the South African Institute of Mine Engineers, and vice versa. Although the SAIME focuses primarily on mining issues, SAICE still provides the general civil engineering support. Personal background Academic qualifications Ph D in Aquatic Health, M Eng in Water Utilisation, B Sc Civil Engineering. Registered as a Professional Engineer. Certified Environmental Assessment Practitioner What are the achievements accomplished during your tenure? The achievements are not mine, but those of SAICE as an organisation. The biggest achievements have been in participating and playing a significant role in getting FAEO constituted after many years of discussions and negotiations. The other has been in establishing closer ties with our fellow professionals in many of the SADC countries, and signing a memorandum of understanding with the Indian engineers. This all sets the scene for an increased involvement in civil engineering on global terms.

Personality Arch. Dr. Ssemwogerere Kenneth Praticising Architect/Project Manager B.Arch. (MUK), MSc Eng& Tech (RSUCE), PhD (Constr. Mgt), President Uganda Society of Architects and Chief Executive Officer of SASA architects. Arch.Dr.Ssemwogerere’spassion for reading, researching and acquiring more knowledge and new ideas to enrich his experiences is incomparable to not many others His eagerness to learn new things and the fact that in Uganda there is a deficiency of latest reading materials for professionals in the construction industry, has led him to open up a resource center, Esterwills Libraryof Engineering & Construction. Located on plot 519 Old Kira Road, this library is stocked with more than 400 latest books on architecture, Quantity surveying, all categories of Engineering and Construction which are highly recommended for architects, real estate developers, engineers and other players in the construction industry with a passion to go beyond the average. Educational background Arch Dr. Kenneth Ssemwogerere, the third born of Mr&Mrs William and Esther Serunjogi, retired Hoteliers, had his Primary education at Buganda road primary school, Kampala from 19811987. He later joined Kibuli Secondary school from 1988-1994 and in1994 joined Makerere University to pursue a Bachelor of Architecture degree where he emerged as the best overall final year architecture student 1998/99 earning himself the USA Presidents award for best architecture student that year. Arch. Dr. Ssemwogerere obtained a Masters degree scholarship from the Russian Government through the Ministry of Education and Sports in 2001. After the Masters he engaged on a selfsponsored PHD in Construction Management and from Rostov State University of Civil Engineering, Rostov-on-Don, Russia. He served as chairman board of research and development 2009/2011 on the Uganda Society of Architects (USA) council. In December 2011 he was unanimously elected President of (USA) 2011/2013. He lectures at the Department of Architecture and physical planning at Makerere University, Uganda. He is also an associate member of Singapore institute of Architects (ASIA). Yet more, he is currently the Chief Executive Officer of SASA architects & Project Managers and has a partnership with some Siamese Architects. To him, Architecture is not only a responsible and paying profession but also
it influences everyday life. His philosophy in life is to be creatively practical in all his designs and to exhibit such admirable levels of competence and commitment in his work. Arch.Dr.Ssemwogerere has attended many International conferences most recent being the 28th annual conference of the Association of Researchers in Construction Management in Edinburgh, Scotland (ARCOM), the Construction and Building research Association Conference(COBRA) in Las Vegas USA. He has compiled several papers from these conferences he has attended and these are available in Esterwills library.

SASA Architects, Engineers & Project Managers Send A Seed Agency (SASA) is a consultancy firm based in Uganda and is set apart from other architectural firms because it’s a root for Ugandans in the Diaspora who have the need to invest back home. SASA has a vision of becoming the Leading Construction Investment Consultancy Firm in Africa, a gateway through which Africans living and working in the Diaspora carry out investments back home. Why the concern with people in Diaspora? During his time in Russia, Arch.Dr.Ssemwogerere was able to fully understand what it actually takes to live, let alone work in a foreign country – the cold winters, strict shifts and long work hours, racial discrimination, stresses of missing the train etc. It is against this background that he developed the passion to ensure that those hard-earned monies are carefully and diligently planned for so that on retirement one can enjoy the fruits of their Labor. He also fully understands that many have been ripped off of their savings and so find it hard to trust anyone back home, but together with his partners, they are more than ready to prove a point that there is still a not only a faithful but professional remnant back home. SASA offers its services in four major areas; project feasibility studies, project design & construction management, project finance management and research in construction.

KK100 Development The tallest building in the world By Emmanuel Onsomu Confirmed by The Council for Tall Buildings and Urban Habitat (CTBUH) as being the tallest building in the world completed in 2011, KK100 is an innovative high density project that takes an entirely new approach to city making. It is situated on the edge of Shenzhen's CBD and sets a new precedent for the successful 21st century transformation of commercial districts into vibrant and enriching environments. The 100-storey, 441.8-metre tower comprising over 210,000m2 of accommodation is part of the master plan for a 417,000m2 mixeduse development. The development includes five residential buildings and two commercial buildings. The floors of the tower are divided into three major functions. The floors from level 4 to 72 house 173,000m2 of Grade-A office space while the uppermost levels from 75 to 100 are occupied by a 35,000m2 6-star Luxury Hotel complemented with a cathedral-like glazed sky-garden animated by various activities. Linking all these elements is the podium that is driven by a retail environment that emphasises local identity, excitement, and economic vigour.
This will become Shenzhen’s most prominent retail address and a destination in its own right. The design provides retail access from every side and there is no dead frontage. Retail mall Car parking for the retail mall is located on the third and fourth floors of the podium, meaning that customers can walk straight from their vehicles into the mall on the same level. This greatly increases the convenience of vehicular access compared to traditional underground car parks. Due to this convenience, and the ease of access to the mall for pedestrians on all sides, for occupants of the tower and for residents of the development, the mall will feel like a naturally connected “high street” rather than an enclosed and isolated shopping centre. The mall thus acts as a connector which links all elements of the development and also integrates it well with the neighbourhood at street level. As well as providing social and cultural continuity, KK100 is integrated with the metropolitan transport network, which is crucial for a high density project such as this. The connectivity between the various components of the masterplan on various levels
was critical; the tower is integrated with the podium on various levels while retail and public uses at lower levels are integrated with the Metro system; the residential blocks are linked at the higher levels to create easier neighbourhood accessibility while direct office and hotel connections are also provided for easier movement of people. The Tower serves as a ‘’Mini-city” which provides an amenity-rich focal point back to the community, offering a 24-hour city-life to be better for the environment and human interaction. Sky garden The public domain extends up the tower, with a "sky garden" housing restaurants and bars, as well as the hotel lobby, located right at the top of the building. This means that the public are not excluded from full enjoyment of the tower, which is all too often the case. The vertical circulation is user-friendly for operations as well public use: (1) Lifts for the office are kept very direct and simple with only one double height transfer lobby. This lobby again doubles up as a public space with opportunities for library, cafes, and viewing areas. (2) The hotel shuttle lifts brings the guests directly from ground-floor up to the 94th floor for checkin. The hotel lobby gives a unique experience
and four local hotel lifts take visitors down to their rooms. (3) In case of fire, shuttle lifts will be used to assist total building evacuation. One of the design features is the curving building profile. This form alludes to a spring or fountain and is intended to connote the wealth and prosperity of Shenzhen. The perimeter column arrangement provides each level with an unobstructed working environment and stunning views towards Lizhi and Renmin Park as well as over all Shenzhen and beyond. It does not use the typical square foot print; the East / West façades being more slender and flared slightly so office floor plates are slightly bigger and the South / North façades that face Hong Kong and the Maipo marshes are wider. The slenderness brings certain challenges, most notably the swing or drift ratio and the robustness of the tower and performance of key elements. Instead of putting generators on top of the building, the roof is constituted by a curved smooth glazed curtain wall and steel structure. With Shenzhen’s growing population, clogged transport systems and an acute shortage of affordable land for development, the increased population density has become a major issue, therefore the logical key to a sustainable future is to build upwards. KK100, a major sustainable form of densification, will play an important contribution to meeting the ever-increasing demand for quality working and living space in the city.
The development accommodating large numbers of people into such a small footprint is better for the environment, as it puts less pressure on green spaces and local transport infrastructure while reducing suburban sprawl. This major mixeduse development promotes the idea of living and working in the same place, and reduces the need for commuting. This lessens reliance on the car, a polluting force, and eases the pressure on public transport. KK100 is a town centre in its own right. From an environmental point-of-view, the advantage of facing primarily North-South (particularly in China) is a reduction in the East and West ‘heat gain’ elevations. The vertical fins help to reduce low-level glare and provide shading. Also, they are important for the fixing of maintenance systems. Major “green” proposals included an environmentally friendly built form and envelope design; energy-saving buildingservices systems; a free-cooling system; and advanced building energy and environmental simulations. During the building’s lifetime, the net aggregate of all these systems will contribute to the limitation of energy use and enhance the profile of the development as an environmentally aware and responsible contribution to the skyline of Shenzhen.

60,000 seat National Stadium for Addis Ababa The Massob, an Ethiopian communal serving basket made from woven grass, inspired the façade material that wraps the stadium Football and athletics-loving Ethiopians will have a new 60,000 seat national stadium and a sports village in Addis Ababa thanks to an international architecture winning design by a Qatari/Australian led consortium's design for a FIFA/Olympicstandard stadium with a sunken arena combining local identity with new technology. LAVA, the LABORATORY FOR VISIONARY ARCHITECTURE, and DESIGNSPORT collaborated with local Ethiopian firm JDAW to win the international architecture competition held by the Federal Sport Commission, Ethiopia. The project is located in the centre of Addis Ababa and will also serve as a meeting place for the community with its water pools and gardens. The design references Ethiopia’s world-famous excavated architecture – centuries old rock churches, dwellings and cisterns. The sports city is a natural extension to this heritage that aims to draw many more visitors to this beautiful country.
The Massob, an Ethiopian communal serving basket made from woven grass, inspired the façade material that wraps the stadium. The form of the stadium structure seen from the top view also recalls coffee beans, the main source of income in Ethiopia and the 'Mother womb', the skeleton of one of the first humans, Lucy, which is about 3.2 million years old. The roof of the stadium, an intelligent membrane, appears like a cloud on the horizon of the vast Ethiopian sky, a lightweight tensile structurefloating over the formed-earth landscape. The masterplan by the JDAW/DESIGNSPORT/ LAVA CONSORTIUM includes the IOC-standard stadium for FIFA matches, athletics events, concerts, religious and national festivals; and a sports village comprising indoor and outdoor aquatic centres, outdoor pitches, sports halls and arenas, dormitories and the headquarters for the Federal Sport Commission. Hospitality, retail and
commercial zones will ensure that the precinct is vibrant throughout the year. Tectonic structures and movement are the underlying concept for the masterplan. The breathtaking beauty of the surrounding Entoto Hills is the backdrop to a design that responds to the volcanic geology of the region. Chris Bosse, who led the design team, and is a director of LAVA, an award winning international firm of architects says: "We have gone back to the very origin of stadium design with the sunken arena surrounded by grandstands formed from excavated material. The man-made crater is a clever remodelling of the existing terrain, integrating facilities within the landscape. It is an efficient use of space which optimises the site's environmental performance while minimising construction costs." Gently undulating urban parkland follows the lines of the crater and is conceived as a continuous spatial experience strategically activated to balance movement, climate, experience and efficiency. A central plaza forms the heart of the project and a ridge connects all zones. Giant solar powered umbrellas provide shade and shelter whilst pedestrian activated light and water features appear as fissures in the ground surface, providing way finding and creating animated art works. Bosse, who was one of the lead architects of the Beijing Watercube whilst at PTW architects, has again combined new technology with traditional architectural principles. The façade patterns are digitally created through parametric modelling and are built with local materials. With sustainable design features, maximum flexibility and capacity, and intelligent adaptability, the new facilities will make a valuable
contribution to the local people, the nation and its culture, enhancing Ethiopiaâ&#x20AC;&#x2122;s sporting profile and generating revenue. Work on the Addis Ababa stadium is scheduled to begin in 2014. The development is the largest sporting infrastructure project in Ethiopia, the second-most populous country in Sub-Saharan Africa and its fastest growing economy. The new facility, set on a 60-hectare site, will consist of a 60,000seat stadium, an athletics track, aquatic centre, residential village, sports halls and arenas, retail and commercial zones as well as the headquarters of the Federal Sport Commission.
Technical Design Consultant for the Doha 2020 Olympic Bid Committee. The building collects the rains and distributes water to be used and recycled for site water management. The solar powered umbrellas are found thought to generate shading and solar powered lighting to the landscape.
Samantha Cotterell, CEO of DESIGNSPORT, a consultancy specialising in sport architecture and event design, who led the bid says: "The brief was to design a centre that would revitalise sport in Ethiopia. The result is a sports venue which can be used by all. It is for community use at a grass roots level right through to providing a high performance training centre for elite athletes and a location for major international sporting events."
Communicating design intent and understanding Ethiopian culture and the application of design concepts in a foreign environment were the main challenges. The other challenge was the budget. The structure is recessed into a sunken area, excavating a man-made crater to set the grandstands reshaping the existing terrain has minimized the overall costs, leading to a proposal which integrates with the landscape and offers an efficient use of spaces to optimize environmental performance.
Cotterell has worked as a senior overlay design consultant on all of Qatar's major sporting events including heading up overlay design for sporting venues for the Doha 2006 Asian Games Organising Committee and acting as Senior
Design Challenges The main challenges of the competition were the designing across continents, cultures and time zones in an extremely tight timeframe. There were architects in Australia, Greece, UK, Qatar and Ethiopia all working on the project simultaneously.

By Yvonne Andiva THarnessing Solar Energy The Sun offers a vast and inexhaustible supply of energy capable of relieving the world of most of its woes associated with its quest to meet its energy needs. To put this massive energy source into context, consider that the amount of energy absorbed by the earth and its atmosphere in one hour is sufficient to meet the world’s needs for a year. Current solar energy technologies rely on harnessing the sun’s rays and include solar heating, solar photovoltaic’s, solar thermal electricity and solar architecture. Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Active solar techniques use photovoltaic panels, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favourable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies. Baraka Solar Specialist In Tanzania Baraka Solar Specialist is a local company that supplies their own branded solar
panels, solar inverters, deep cycle solar batteries, solar chargers, garden lamps, solar lanterns , solar generators among other solar products. According to the company, the local industry is plagued by low purchasing power, the perception that solar products don’t offer satisfactory power as well as the existence of poor quality fake products. Baraka Solar Specialists despite these odds has gone on to corner a sizeable market share especially in the government funded sector. These include health centers, dispensaries and schools. They note that in order to promote the industry the government needs to impose strict importation regulations and inspection to ensure product quality. In addition awareness needs to be created and loans provided to stimulate growth inthe use of solar products. Equator Sun (U) Ltd Solar water heating offers considerable energy savings both for residential and institutional establishments according to Equator Sun who supply solar water heating solutions in Uganda. The company’s products are durable and aesthetically appealing while being reasonably priced according to Allan of Equator Sun. Allan goes on to point out that lack of awareness, poor maintenance regime in Uganda, dumping of inferior goods on the market are issues plaguing the solar energy industry in the country. He points out that government needs to introduce legislation to reward users of solar energy.

Allan lets on that currently there is an offer by the Private Sector Foundation Uganda (PSFU) in which they subsidise the cost of installing a solar power unit but this is for a limited time only. Roof top installations The most interesting and impressive applications for solar in the context of the building environment is industrial buildings that generate part of their own electricity on their roofs. This is an application that will sooner or later be omnipresent all over Africa. Because electricity prices are sharply rising, especially when Diesel combustion is used to generate this electricity and industrial clients including the mining industry are quite aware of this. This group of clients can afford the initial investment necessary to then run the solar PV electricity system as solar system are practically without any running costs as the sunlight is for free. The existing grid infrastructure of industrial buildings makes connection to the grid very easy and actually helps the electrical grid rather than putting any burden on it. In addition, there are no security issues on rooftops of existing buildings as the buildings are under constant vigilance.Abakus Solar AG is one of the leading companies when it comes to real big roof top installations on an international level.

Shamla Fernandes Architects In consultancy, realizing the client’s aspirations is probably the most important component of a lasting relationship. But as CR found out at Shamla Fernandes Architects in Nairobi, Kenya, there is more to that. Kenya
Shamla Fernandes Architects was established in 1999 as a husband and wife partnership to offer the full range of architectural services (and gradually interior design as well).
Architecture is a constantly evolving discipline, with new systems, technologies and materials emerging every day and clients becoming increasingly knowledgeable and therefore more discerning. The trend has seen architects everywhere grapple with these changes and new demands. Notwithstanding the dynamism of architecture, one cardinal factor remains constant and unchangeable: the need to fulfill the client’s expectations and ultimately create a structure that is satisfying to both parties and positively impacts the built environment. This fundamental principle sums up the guiding philosophy at Shamla Fernandes Architects, an architectural and interior design practice based in Nairobi, Kenya. Shamla Fernandes Architects was established in 1999 as a husband and wife partnership to offer the full
range of architectural services (and gradually interior design as well). Since then, there has been no change in the firm’s structure and the couple, Shamla and Feo Fernandes, have continued to offer these services as well as manage the operations with a small team of support staff. Thirteen years is a short time and one would expect that the practice is only beginning to mature and possibly just getting to undertake complex projects. However, within this period, Shamla Fernandes Architects already have hotels, office complexes, schools and other large public utility projects in their portfolio. In a wide ranging interview with CR at the firm’s offices at Yaya Centre, a prestigious address in suburban Nairobi, a relaxed Shamla takes it all in stride,
attributing their successes to professionalism and good work which in turn earn them referrals. Background After working with some of Kenya’s best known names in architecture – Beglin Woods and Planning Systems Services – and gaining invaluable exposure, Shamla felt a need to move on as an independent consultant. The move would not only give her freedom but would also enable her to look after her young family more effectively. A year after leaving Beglin Woods, Shamla was joined by her husband Feo and together they were well on their way to creating a highly efficient team that is today credited with such elegant facilities as the Crowne Plaza, a popular hotel in Nairobi that is part of the Intercontinental Hotel Group, and the recently completed West End Towers, an office complex in the capital city. “For many years, we operated from our home”, says Shamla, adding that they have built a varied client base, many of whom have become repeat clients. They have been at the Yaya Centre office for the last six years. Because most of their work in employment involved commercial projects, Shamla Fernandes
Architects have tended to favour these projects, something that can be attested to by the large number of such projects whose pictures grace one of the walls in the firm’s boardroom. This, however, is not to say that they do not take on residential and other projects. Their stable consists of several residential houses and apartments. Getting Jobs Shamla Fernandes have relied almost exclusively on word of mouth to get work. According to Shamla, many of their clients come to them on a walk-in basis having been referred by former clients or people in the industry who already know that the practice does good work. Aggressively competing or soliciting for jobs is not favoured at the firm. “However, there has been the odd competition here and there”, says Shamla. “For example, Crowne Plaza was a competition, which we won”. So does it mean work is always flowing? “There have been times when we have not been busy”, Shamla acknowledges, saying that such periods give them a chance to relax and even re-organize their offices. “However, we find that most of the time we have work at

different stages; some at design, other at approval while the rest may be at implementation stage.” Relating with Clients Shamla Fernandes Architects believe in giving the client what he or she wants and not what they feel the client should have. They recall an incident during the practice’s early years when a priest showed up at their door. This was one of those slow periods when work was barely trickling in. “A priest appeared at our door and said: ‘Look, here’s a sketch of a church we want to put up. I’ve been to several places and every time I show my plan, it’s kept aside and I’m offered something different. I don’t want their building; I want my building.’” This experience reaffirmed the need for Shamla Fernandes to listen to the needs of the client.During the first encounter, SFA listen keenly to the client’s brief. It is this brief that forms the basis of the professional advice the client will receive. According to Shamla, an interplay of many factors influences the final decision on a project. Important elements include budget, site considerations and building regulations including bylaws. Some clients would like to put up a building but have no idea how much it would cost. “Some are shocked when you give them an estimate”, says Shamla, adding that this calls for a plan to work around the available funds. According to Shamla, the firm does not compromise on quality and regulatory issues. They will stick to the law and insist of a professional approach to every angle. “We’ve been at loggerheads with a few people including contractors because of sticking to our position on these issues”, she says. However, this uncompromising stance has actually earned the firm respect.
“Green” Buildings Today, as the clamour for sustainable buildings rages, many developers are increasingly asking their architects to incorporate green aspects such as water recycling and solar energy harnessing. While Shamla Fernandes have been November 2012
involved in several such developments, not all clients are willing to invest accordingly. Says Shamla: “Some of the green features require large capital outlay whereas the savings are not likely to felt until much later. Therefore, developers tend to shun this expenditure and settle for the ordinary building”. Job Satisfaction At Shamla Fernandes, design is a passion. Whereas some architects have gradually been taking up the role of developers and eventually going into property development, this is not likely to happen with the partners at Shamla Fernandes. So immersed are they in their work that they are constantly creating new designs. “No two of our buildings look alike”, states Shamla. At the end of the day, job satisfaction and pride comes from successfully completing each project to the client’s satisfaction – be it the restoration of a decrepit structure or the creation of a new building. Industry According to Shamla Fernandes, the construction industry in Kenya faces various challenges.As a seasoned consultant, Shamla decries the shortage of dedicated professionals saying that many professionals today, especially the young ones, are in a hurry to climb the ladder and make money at the expense of the tenets of good practice. On the brighter side, she is full of praise for some changes at the City Council of Nairobi which have tremendously improved the pace of approvals for architectural and other plans. She says the e-Construction Permit Management System (e-CPMS), which enables architects to monitor the status of plans that have been lodged with the Council, has been of immense help. Future In the foreseeable future, Shamla Fernandes Architects will continue doing what they do best: giving the best advice possible and guiding clients to the full realization of the latter’s aspirations.

MRM Introduces a New Multi-Storey Building Solution Multi-storey buildings in steel have been used extensively in Europe and surrounding areas since the 1940’s. With today’s advanced technology and latest innovations, the use of structural steel and concrete composite design is being applied in the construction of multi-storey buildings. In addition to a faster construction speed an increased economy is achieved when applying such design techniques. DECKING SHEETS Decking sheets are fixed to the top of the beams (steel, RCC or any other material) with self drilling screws. The decking sheets are designed to free span between the beams, therefore eliminating the need for props and shuttering during the casting of the concrete slab. This makes the construction method very quick and efficient since the contractor does not need to wait for the curing time of the concrete slab before moving to upper subsequent floor levels.
TECHNICAL SPECIFICATIONS OF DECKING SHEETS (All dimensions in mm.)
• • •
An Aluminium-Zinc coated angular trough profile is used with thickness varying from 0.5mm to 0.7mm depending upon the design load. The decking sheets acts as permanent shutter supporting both the construction and final design loads and therefore the bottom of the shutter acts as the slab soffit finish. The composite steel beam and concrete deck system can be designed to accommodate loads of 2.5Kn/m2 for light weight office blocks and 10.0Kn/m2 for heavy industrial load and car park systems. As the design load increases additional reinforcement can be added to the slab to resist high shear loads and longitudinal loading stress.

Kenya National Spatial Data Infrastructure (KNSDI) Administration Block Project Information The project is a new administration block for the Ministry of Landâ&#x20AC;&#x2122;s unit called Survey of Kenya based in Ruaraka, Nairobi. The building will house 1000 square meters of space comprising of office space, a conference hall, a lecture theatre, a Geotechnical Information Systems (GIS) lab, an open-air cafeteria, a state-of-the-art document and map press room, and basement storage area. The cost of the project is slightly under one billion Kenya shillings. The construction of the building was to take three years beginning in May 2011 and the completing
on May 2014. The project is currently ahead of schedule and is in the finishing stage. The main contractor is Vaghjiyani Enterprises Ltd. The project is progressing well and the remaining major works are exterior civil works and landscaping. Current approximate date of completion goal is May 2013. Challenges This project had some unique challenges since it was to house some of the latest digital press machines and a futuristic GIS lab. The press machine covers an area equivalent to what a
40-foot container(12m x 2.5)would occupy and weighs roughly 50 tons (50,000Kg). There will be two of these 6 color digital presses, roughly costing Ksh 300 million. The sheer weight of these machines demanded that careful design decisions were made which included placing them in the basement and on solid ground rather than on suspended slabs. Issues or climate control had to be taken into account since digital printing requires controlled humidity and temperatures.

The Best of 2012 The 2012 SAISC Steel awards held in September of this year produced a number of significant competitors in from the local construction industry
In spite of the continued lull in the construction industry, the projects nominated for awards were anything but scrapings from the bottom of the barrel. Judges at the event had a difficult choice to make between the flue cans at the Medupi Power Station in Limpopo Province, the brilliant restoration of a medical facility in Hillbrow, a beautiful pedestrian bridge in Bloemfontein to an innovative head office in Pretoria, an aesthetic masterpiece on Westcliff Ridge in Johannesburg and the new home of Architecture at the University of the Free State and a complex as well as a beautiful canopy in KZN. “We congratulate the winners, but emphasise the exceptional quality of all the entries,” said Dr Hennie de Clercq, executive director of the Southern African Institute of Steel (SAISC). A comment that he did not make lightly. Awards presented In all, seven projects walked away from the evening with awards. The “Architectural” and “Light Steel Frame Building” categories were combined into one award this year this year, and presented the combined award to the Boogertman + Partners
Architects-designed Deloitte Head Office, situated at the Riverwalk Office Park in Pretoria. This was the first time in the history of the awards ceremony that the two awards had been combined. The decision was motivated by the unique qualities of the building, which displayed remarkable qualities both in the use of architecturally exposed steel as well as the cutting-edge application of the Light Steel Frame Building method. Along with Boogertman + Partners, Spiral Engineering, which was responsible for the structural steel aspect of the building, walked away with bragging rights on this award. The transformation of part of the derelict 1928 Operating and X-Ray building into the new Shandukani Centre for Specialised Servicestook the honours in the Sustainable Development Category. The project has received significant media attention since its start. The objective was to create the facility from an existing building that was part of the old facilities. The challenge was, however, to preserve this historical landmark and the modern additions were not allowed to impact on the older parts of the building. Next, there
was the renovation of the structure that houses the Architecture Department at the University of the Free State, which won the Sustainable Development Commendation and the Hanger Street Pedestrian Bridge, stretching across busy Hanger Street in Bloemfontein, walked away with the honours in the Bridge category this year. The award in the Tubular Categorywent to the Dube Square Canopy at Dube City adjacent to the King Shaka International Airport and the Architectural Commendation went to a dwelling in Westcliff, Johannesburg. Victor of the evening Finally the overall winner, the steel flue cans at the Medupi Power Station in Limpopo, also won the Mining and Industrial category prize. The project was in fact submitted to the judging panel as two separate entries. The first was the platform steelwork designed to give access for future maintenance, to assist in overall erection inside the concrete chimney and to support the hanging mass of three 9m-diameter ceramic-lined flues and a concrete roof to the chimneys. The second
entry was the actual steel cans that make up the flues. In the end however, the entries were grouped into one owing to the fact that they were integrally linked. The platforms surrounding the three 9-m diameter cans led to a conceptual layout that relied on three radial beams, each 17m long, joined together in a â&#x20AC;&#x153;central three-way jointing connection fabrication. Once this main spine and support system has been resolved, the secondary beams are framed into these main girders providing support for the grating floors that are shaped to accommodate the circular openings to allow the cans to pass through the floors.
Each can is 9m in diameter and made from stiffened 8mm thick plates. The 18 uppermost cans are made of stainless steel because of its corrosion resistance properties, as they will be exposed to acid corrosion. Once the decision to make the cans site-bolted and seal-welded was reached, the next decision was to make the sub-cans into 9m lengths (based on 3m-wide plates) with bolted flanges. The circumferential length is made by joining 3 plates. Behind this impressive winner there was also a rather large project team, the members of which were comprised of skills Eskom Holdings, Karrena â&#x20AC;&#x201C; Germany, MM&G Mining and Engineering Services (which was responsible for the steelwork as well as project management as well as steel work on the flue cans, Concor in joint venture with Karrena, Aveng Steel Fabrication and PCP Drafting. The list goes on with Beroa Deutschland, PB Power and Robor Galvanizers, Bulldog Projects and Aveng Steel Fabrication which worked on the structural steelwork of the chimneys. With the Steel Awards at an end, one wonders what the next year in steel construction will bring. If the projects are this impressive during a recession, the possibilities for the industry once the construction sector picks up again, seem limitless.

MM&G Mining and Engineering Services
MM&G overall winner at 2012 Steel Awards
MM&G Mining & Engineering Services walked away as the overall winner at the 2012 Steel Awards. The giant chimney flues and platform steelwork project the company completed at the Medupi Power Station in Lephalale, Limpopo, also won the Mining and Industrial category prize. The annual Steel Awards, presented simultaneously in Johannesburg, Durban and Cape Town on 6 September, serve to recognise and applaud exceptional achievements within the steel industry and aim to recognise and promote excellence and entrepreneurial development in the industry, principally in South Africa, by profiling innovative thinking and successes from the industry, both locally and internationally. Boksburg based MM&G competed with entries from local as well as international individuals and companies involved in the production, conversion, distribution, use of recommendation of carbon and stainless steel. MM&G received the order for a fast track project on the Medupi Power Station in December 2009, said CEO Dawie Vos. “The project entailed the supply and fabrication of flue gas ducting for two 220 meter high chimneys, each containing three flues. This was the largest project MM&G had ever attempted and completed successfully in its 34 year history. The timely construction and handover of 120 steel units, consisting of 18 stainless steel units (316L material), 102 mild steel units (S355JR material) and the remainder of 24 mild steel lobsters (S355JR material) are evidence that MM&G can compete with the best,” said a proud Vos. The judges stated that in spite of strong competition from the other four category winners, the fabrication of the complex platforms and flue cans for the world-class Medupi chimneys truly showed the “wow” factor that separates the 2012 Steel Awards winner from the rest. The total weight of all the units was approximately 2400 tonnes, of which the stainless steel component accounted for 330 tonnes and the mild steel components, including lobster, accounted for 2070 tonnes. Jurie Human, project director, said there seemed to be a perception that MM&G would be unable to complete the project within the agreed upon time frame. “We proved the nay-sayers wrong. We fabricated our own workshop in record time on the Medupi site during January and March 2010, and the project started in all earnest in May 2010
with the first items of diameter studies, and the first trial assembly done in our Boksburg Workshop,” said Human. All the components for the first three flue gas ducts, for the South Chimney, were due for completion by 20 March 2011, a date to which MM&G kept as a result of excellent planning and execution of the project, said Vos. The completion date for the second delivery of flue gas ducts, for the North Chimney, had been set for 20 October 2011, and was completed early on 9 September 2011. The total design of the interior stiffening and fabrication methodology for the flue gas ducts was done by MM&G, and was monitored by a computer programme specifically written and developed for this project in-house. Just in time delivery of value added raw material from the Aveng Trident Steel group contributed to the successful delivery of the entire project. “The strategy was developed around a definite goal with handpicked individuals to deliver the project. The fact that the same project team worked on the project from commencement to completion, played a considerable role in our success. The same key people who designed and planned the project, also brought it to a successful conclusion, and are still with the company today,” said Vos. MM&G did face some safety challenges on the South Chimney with two lost time injuries during November 2010. They learned from the mistakes made, and after that MM&G maintained an excellent safety record throughout the project. The fabrication and erection of the flue gas ducts was completed without fatalities to the workforce, consisting of an average of 80 workers, increasing to a work crew of 107 at peak production times. MM&G is particularly proud of the fact that the project was completed with local content and workforce. “There were challenges to overcome, some delays due to labour strikes and xenophobic unrest, as well as the harsh weather circumstances in which the project had to be completed. Our workforce endured and persevered in temperatures that had the mercury rising to up to 54°C. Despite these potential stumbling blocks MM&G managed to complete the work within the agreed upon time frame,” said Vos. MM&G maintained an excellent quality record: The company experienced no quality rejections throughout the project, and to date there have been no rejections due to any defects. This success can be attributed to MM&G's 100% ISO compliant Quality system, said Vos.

Concrete infrastructure placed South Africa
The precast concrete market in South Africa is severely competitive and the big players in this arena are constantly looking for the next big project. Two of the most prominent names in the industry have recently commenced large projects of their own. While most players in the industry mainly supply precast piping, it is worth noting that most of the prominent names have developed extensive ranges for their concrete products from culverts and piping to poles and even guard boxes. The possibilities seem limitless. Midrand project Approximately 5,000 metres of precast concrete stormwater pipes will be used to drain Waterfall City, which have been specified by the Johannesburg Roads Agency (JRA). Regarded as one of Gauteng’s largest infrastructural projects to date, Waterfall City is currently under construction and is earmarked to become Midrand’s new central business district. Driven by Atterbury Property Developers, the initial Waterfall City development will comprise 800,000 square metres of rentable space when completed. Spanning 125 hectares, the site forms part of a 565 hectare estate. The professional team includes C-Plan Consulting Engineers, responsible for infrastructural planning and project management, with Labucon Resources handling a major portion of the earthworks, road infrastructure and the installation of stormwater, fresh water and sewerage piping. Rocla was selected as one of the suppliers of concrete stormwater pipes. The stormwater drainage project, which commenced in November last year, is due for completion in early 2013. The pipes ranging in diameter from 450mm to 1,950mm will drain the site and discharge into
three water channels, which will ultimately feed the Juskei River to the south. According to KC Oojkaas of C-Plan Consulting Engineers, all roads are constructed to JRA standards, which specify concrete stormwater piping. “Precast concrete is the best material for stormwater drainage due to its strength and durability, which is why it forms part of our roadbuilding specifications.” KC Oojkaas adds, “The stone bedding prevents any soil movement from exerting excessive pressure on the pipe joints. A laser-beam is used to ensure that the pipes are properly aligned.” Wingwalls minimise erosion Wingwalls are being installed where the pipes discharge into the water channels to prevent soil erosion. According to Sias Swart, Labucon Resources Site Manager, the Waterfall City project is setting a precedent in that two of the wingwall outlets are being custom manufactured off site at the Rocla plant, instead of in situ. Rocla precast wingwalls, which were recently introduced to the South African market, offer numerous benefits, which include quicker installation, lower material requirements, no formwork and no wastage, were approved by JRA for this project. “In stormwater applications, wingwalls direct the water into and out of pipes resulting in the reduced turbulence, thereby optimising the hydraulic capacity of the conduit,” says Craig Waterson, Sales and Marketing Director of Rocla. “Precast wingwalls come with a separate precast concrete toe which keys the entire unit to the ground, and prevents any movement, while also reducing the risk of scouring of the soil below or to the side of the toe.”
Housing project underway Competitor, Infraset is also active in the Roodepoort area, not far away from Midrand. The Aveng Manufacturing subsidiary has been contracted to supply over 3 000 prestressed I-shaped concrete poles for the electrification of a fully integrated housing development in Fleurhoff, in Roodepoort, Gauteng. The entire development involves the construction of 9 600 houses varying in size between 30 m² and 100 m², with some units to be sold on the open market and others falling under the Reconstruction and Development Programme umbrella and the remainder allocated for social rental and the gap market. The construction programme began in 2010 and will run to 2016. The poles are being installed by Kusokhanya Electrical Construction. An average of 30 poles a day are being planted by KEC. Aveng Manufacturing Infraset poles and masts product manager Mothemane Makhura says all the I-poles for the project were manufactured with earthing bars to protect them against lightning. “The I-poles were cast at our Brakpan factory in high-strength, high-density concrete with a smooth finish. They are functional yet relatively light, which makes them easy to handle. The high strength-to-weight ratio of the I-shaped poles puts them in a class of their own. “The resilience of prestressed concrete poles enables them to recover from the effects of a greater degree of overload than any other type of structural material,” he says. In a slow economy like this one, it is heartening to see that the infrastructure that has to pave the way for development, is being built. November 2012
Steps to Safety Lighter, stronger fibreglass technology in the making One often forgets the versatility of a technology like fibreglass. It is safe to say that the excitement over the technology that hit the industry in the 1930’s has died down. The fact is however that there is still much to be excited about. And there are quite a few companies like the one mentioned below, that are still making strides in the development of fibreglass. The recently released Econotread stair tread from Vital Engineering not only offers a significant reduction in cost and mass of materials used, but results from a recognised testing institution show an incredible 35% improvement in its load ability when compared to traditional branded stair treads. Vital Engineering, which is synonymous with the manufacture of all types of quality gratings, stair treads, pressed floors and safety handrails, has to
date invested a substantial amount of its income in the research and development of products that will improve safety and productivity in industrial, mining and commercial environments. During extensive pre-launch testing the Econotread exhibited a 15% saving on costs when manufactured in mild steel and galvanised finishes and even larger savings when stainless steel and aluminium are used as the material of construction. “The Econotread utilises our Vitagrid raised serrated pattern gratings which provides superior non-slip characteristics compared to plain gratings. The combination of our engineered Econotread and Vitagrid provides a practical and cost-effective solution for our clients,” says Dodds Pringle, Managing Director of Vital Engineering. “With an increase of the number of slips, trips and
falls throughout industry, clients are demanding stair treads that eliminate or at least substantially reduce these incidents of injury or fatality. The leading edge and durable bulleted self-cleaning non-slip nosing of the Econotread ensures an excellent grip irrespective of whether one is ascending or descending the staircase,” he says. By attaching a bright yellow reflective strip to the leading edge of the tread, visibility and safety are improved in low light or poor conditions. All Vital Engineering products are engineered to EN-ISO9001-2000 standards to ensure the highest quality levels and standardisation of application. Pringle explains that the design of the Econotread allows for the use of the same type of fixing details of a bolt in tread, which alleviates
South Africa 42
the need to redesign stringer holes. “In addition, the extended slot of the tread means that it can be used in a variety of hole centres. This is significant since it can be used with a multitude of manufacturer brands and side plate details, thus further reducing cost and aggravation for clients.” “We take our lead on new product development from the industries we serve and safety features top of the list for the majority of our clients. However, we are cognisant that in the ongoing economic crisis companies need to find smarter ways of conducting business in order to remain sustainable. The Econotread allows us to offer a product that meets the stringent OHS criteria laid down by our most demanding clients, while at the same time providing them with a product which affords them a better return-on-investment,” Pringle concludes.
“The coastal climate is extremely conducive to high levels of corrosion which results typically in products rusting and becoming a safety risk,” says Pringle. “An example of a highly corrosive area is Richards Bay where our Vitaglass products are finding a wide acceptance due to their long-term cost saving and improved safety,” he says. “Our decision to manufacture the Vitaclip stainless steel fixings for our fibre glass grating is a natural evolution of our focus on a customer-oriented business philosophy,” says Pringle. “And, as with all of our products, the Vitaclip is the result of our industry experience and insistence on using only the highest quality materials of construction.” “Our service levels extend to offering standard sheets, trench covers and angles as well as stair treads. We also, manufacture cut-to-size panels from drawings in our Vitaglass range, which eliminates our customers having to manage changes to their ISO 1400 and 1800 systems. This effectively allows us to utilise our resources in an area in which we are both highly experienced and competitive,” Pringle concludes.
Fibreglass step-up It is not just in the area of walkways where modern fibreglass is making significant inroads. Fibreglass ladders like the models supplied by Trugrid are present at the most prominent mines and construction projects in the industry. Trugrid reports that the company has sold its products to mining houses like AngloGold Ashanti and Sasol and their ladders were also present on the Gautrain Tunnel project. The company is however not content to merely provide a product but also support in the form of training. This often overlooked aspect of health and safety on a construction site is addressed by the company which states, “The major causes of ladder accidents have been identified as being stability related indicating an underlying lack of understanding of the safe use of ladders. Trugrid Sales recognises the importance of ladder training and offer a half-day ladder training course as a service to our customers.” With that it seems that the future for this technology is just starting to speed up and fibreglass is step-by-step entering the most unexpected applications. South Africa
Other expertise The company has however not limited its expertise to steel. “As best practice, we carefully analyse the systems that suit our customer’s specific applications and we work closely with them to ensure that our product specifications match their expectations,” says Pringle. The company’s high quality GRP fibre glass gratings were designed and manufactured in response to a request from
its coastal customers who were experiencing issues with coated steel products.

Fibertex SA’s state-of-the-art manufacturing plant
Fibertex geotextile filtration layer in breakwater, Palm Islands, Dubai
Innovative Construction Materials Rod Claus explains some basic points on the subject of geosynthetics
Geosynthetics are the generally polymeric products used to solve civil engineering problems. This includes eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells and geocomposites. Technical Marketing Manager at Fibertex South Africa, Rod Claus starts his presentation by pointing out that the polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required. Properly formulated, however, they can also be used in exposed applications. Geosynthetics are available in a wide range of forms and materials, each to suit a slightly different end use. These products have a wide range of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic, and private development applications including roads, airfields, railroads, and embankments, retaining structures, reservoirs,
canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture and agriculture. Categories of Geosynthetics Geotextiles are permeable fabrics which, when Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (looks like mail bag sacking), needle punched (looks like felt), or heat bonded (looks like ironed felt). Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Overall, these materials are referred to as geosynthetics and each configuration—-geonets, geogrids and others—-can yield benefits in geotechnical and environmental engineering
design. Geogrids represent a rapidly growing segment within geosynthetics. Geogrids are polymers formed into a very open, gridlike configuration, i.e., they have large apertures between individual ribs in the transverse and longitudinal directions. There are many specific application areas, however, they function almost exclusively as reinforcement materials. Geonets, called geospacers by some,another specialized segment within the geosynthetics area. They are formed by a continuous extrusion of parallel sets of polymeric ribs at acute angles to one another. When the ribs are opened, relatively large apertures are formed into a netlike configuration. Two types are most common, either biplanar or triplanar. Their design function is completely within the drainage area where they are used to convey liquids of all types.
New developments underway at Century City Cranes are back on the skyline at Century City in Cape Town, with new developments totalling more than R1-billion under construction and more in the pipeline. John Chapman, a director of Rabie Property Group, said Century City had continued to outperform the office market generally and while many other nodes were showing a significant increase in office vacancies, Century City’s vacancies had dropped to an all-time low of around 6% which was prompting significant new office development. “In fact of the current construction projectsseven are new commercial projects totalling more than R700m. Very few of these projects are speculative
and most of those that are have already secured tenants so we expect the overall vacancy factor will continue its downward trend.” Commercial projects under construction includenew 9000 square metre regional offices for Chevron, a 4000 square metre offices for Business Centre and the 4000 square metres BridgewayNumber 3 development at a total cost of around R160million. They are situated in the new Bridgeway precinct which, when completed, will comprise over 150 000 square metres.

All three building are being built according to environmentally friendly principles and are aiming
Geomembranes represent the other largest group of geosynthetics. Their growth is stimulated by governmental regulations originally enacted in the early 1980s for the lining of solid-waste landfills. The materials themselves are relatively thin, impervious sheets of polymeric material used primarily for linings and covers of liquids- or solidstorage facilities. This includes all types of landfills, reservoirs, canals, and other containment facilities. Thus the primary function is always containment as a liquid or vapor barrier or both. The range of applications, however, is great, and in addition to the environmental area, applications are rapidly growing in geotechnical, transportation, hydraulic, and private development engineering. Geosynthetic clay liners, or GCLs, rolls of factory fabricated thin layers of bentonite clay sandwiched between two geotextiles or bonded to a geomembrane. Structural integrity of the subsequent composite is obtained by needlepunching, stitching or physical bonding. GCLs are used as a composite component beneath a geomembrane or by themselves in geoenvironmental and containment applications as well as in transportation, geotechnical, hydraulic, and many private development applications. Geofoam is a product created by a polymeric expansion process resulting in a â&#x20AC;&#x153;foamâ&#x20AC;? consisting of many closed, but gas-filled, cells. The skeletal nature of the cell walls is the unexpanded polymeric material. The resulting product is generally in the form of large, but extremely light, blocks which are stacked side-by-side providing lightweight fill in numerous applications. The primary function is dictated by the application; however separation is always a consideration and geofoam is included in this category rather than creating a separate one for each specific material. Geocells (also known as Cellular Confinement Systems) are three-dimensional honeycombed cellular structures that form a confinement system when infilled with compacted soil.
Construction of the Hong Kong International Airport
Extruded from polymeric materials into strips welded together ultrasonically in series, the strips are expanded to form the stiff (and typically textured and perforated) walls of a flexible 3D cellular mattress. Infilled with soil, a new composite entity is created from the cell-soil interactions. The cellular confinement reduces the lateral movement of soil particles, thereby maintaining compaction and forms a stiffened mattress that distributes loads over a wider area. Traditionally used in slope protection and earth retention applications, geocells made from advanced polymers are being increasingly adopted for long-term road and rail load support. Much larger geocells are also made from stiff geotextiles sewn into similar, but larger, unit cells that are used for protection bunkers and walls. A geocomposite consists of a combination of geotextiles, geogrids, geonets and/or geomembranes in a factory fabricated unit. Also, any one of these four materials can be combined with another synthetic material or even with soil. As examples, a geonet with geotextiles on both surfaces and a GCL consisting of a geotextile/bentonite/geotextile sandwich are both geocomposites. The application areas are numerous and constantly growing. The major
functions encompass the entire range of functions listed for geosynthetics discussed previously: separation, reinforcement, filtration, drainage, and containment. Advantages of properly manufactured materials The manufactured quality control of geosynthetics in a controlled factory environment is a great advantage over outdoor soil and rock construction. Most factories are ISO 9000 certified and have their own in-house quality programs as well. The thinness of geosynthetics versus their natural soil counterpart is an advantage insofar as light weight on the subgrade, less airspace used, and avoidance of quarried sand, gravel, and clay soil materials.The ease of geosynthetic installation is significant in comparison to thick soil layers (sands, gravels, or clays) requiring large earthmoving equipment. Published standards (test methods, guides, and specifications) are well advanced in standardssetting organizations like SANS, ISO, and ASTM. Design methods are currently available in that many universities are teaching standalone courses in geosynthetics or have integrated geosynthetics in traditional geotechnical, geoenvironmental, and hydraulic engineering courses.

HDPE flexible slotted drainage pipe with smooth bore Soil
Drainex drainage pipe has an innovative double wall
sandwich construction, with a corrugated outer wall and a smooth inner wall. This combines high ring stiffness with excellent flow characteristics. It is available in coils and 6m lengths. Rows of water in-take slots are symmetrically arranged around the apex of the pipe (240Â°) with a flow channel at the bottom (120Â°). The high infiltration area combined with the thin inner wall structure ensures optimum water intake. The slots are protected in the valleys of the corrugated structure which reduces the possibility of blocking. The smooth bore with an extremely low roughness coefficient results in greater flow rates, allowing the utilisation of smaller diameter pipes.

actual cost of the door, due to the tight deadlines and potential penalties that building contractors may incur, “says Wayne Furness, co-owner of Roll-Up Serranda. The company has been South Africa's pre-eminent supplier of roller-shutter doors for over 55 years, delivering on customized, bespoke individual doors and large scale projects such as Gautrain's tunnels and stations, high-end retail chains and many of the Soccer World Cup's stadia. Recently added to the list was an enormous project at Rea Vaya's Dobsonville bus depot. "Our involvement started in May 2010," says Furness, "where customized and fit for purpose doors were proposed, designed and incorporated into the final overall end design. The order finally came in a year later and construction commenced in March this year.”
Project architect, Arup's Daniel Joubert, says "Roll-Up Serranda was specified at the onset of our design process due to their reputation and the quality feedback we received on their product.”
"This detailed involvement characterises the way we like to work with clients," he adds, "and is part of the reason why Roll-Up continues to be specified as

hardware - they are paying for reliability and for peace of mind knowing they will not be let down when it comes to the final deadlines being met.
Rapid and now environmentally friendly In an age of lively environmental consciousness, Rea Vaya has stepped up to the plate to play its part. Its depot now recently completed in Dobsonville, Soweto bears testament to its green aims.
Sebastian Adams, a quantity surveyor, explains that Lexan is durable and will last for a lifetime. He points out that the depot could be one of the first in Joburg to use Lexan for walling. “It is normally used on the rooftop of some buildings.” Lexan comes with other environmentally friendly perks: by its nature it can act as a temperature regulator. On hot days, it can cool the temperature. And on cold days the material can absorb and retain solar heat, thus minimising the use of air conditioners and heaters. Natural light incorporated Another advantage lies in the material’s transparent nature. “The Lexan works well as it eliminates the use of multiple light bulbs by allowing natural lighting into the building,” says Adams. To boost the use of natural lighting, clear transparent plastic skylights have been installed on the roof of the administration block. Similar
innovations can be spotted elsewhere: the doors at the northern entrance are made from clear glass. Energy saving is what the building is all about, and on the walls of the office areas there are no light switches. This is because it operates on sensor lights – the lights switch on when someone enters a room, and switch off automatically when the person leaves again. In the same vein, the maintenance block has solar panels on its roof, which are connected to solar geysers. Pointing to the building, Silvino Page, the site co-ordinator says that once it is finished, the geysers will provide hot water to the bathrooms and basins. Automatic press taps have also been installed as a measure of saving water. Page gives assurances that the geysers will work just as effectively as electricity powdered geysers. “They are very powerful and can absorb a lot of energy from the sun,” he explains. To boost natural lighting the admin block is fitted with Sky lights on the roof. Separating oil and water The green endeavours on the building are far reaching. Other smart environmental protection engineering are the oil-water separators in the maintenance room and the wash bay area. The separator will come in handy during regular maintenance and washing of the buses, which often involves the drainage of water and oil. It will isolate oil and water into separate storage areas. “When the oil storage has filled up, it will then be
taken for recycling. Water will go into the drains,” remarks Adams. The same facility will also be installed in the wash bays. He explains: “When the buses are being washed underneath on the chassis, some oil will come out, though it wouldn’t be much, as in the maintenance area.” Another fascinating feature of the depot is the noise barrier wall at the back. The wall, normally used by airports, keeps noise within the yard, and can even contain large noise effects. Some out-of-the-box thinking came through in the building’s design. For example, in an effort to contain air pollution, the room in the maintenance block set aside to spray paint dents on the buses has been specially designed to trap the paint smell from going out into open air. Even the decorations are designed to complement the environmental element. Once work is finished, there will be a large storm attenuation pond, which will store rain water to be used to water a small garden that will be planted around the pond. Adams points out: “This will create a more natural atmosphere.” He reckons that the price of the material used is modest in comparison to what the company would have paid it had built with concrete or other regular materials. Work on the depot started in October 2011, and was due for completion in July 2012, but it was delayed by rain. The delay was not long however and as of September of this year, the depot has been fully operational.

From its design, the top-class depot – which is on the verge of completion – has booked a place among leading green buildings. And its natural but contemporary design is something of beauty, and it stands tall among the humble homes of the township. First off, a great deal of the material used in construction is environmental friendly. There has been relatively little use of concrete, and the structure of the bus maintenance section and the administration block is made of steel. On the sides it is covered with Lexan, a slightly transparent, plastic-like material.
