The Site Board African Power Sector

WRITERS Irene Kabuzire, Elaine Young, Emmanuel Onsomu, Newton Mthethwa, Lindsay Wagner

The African energy sector is characterized by very high energy prices, insufficient and unreliable supply of power and very low rates of electrification. Africa consumes a meager 3 percent of the world’s electricity with connectivity remaining relatively low, with rates averaging 43 percent.

WEB & GRAPHIC DESIGN Augustine Ombwa Frankline May Moses Ngunjiri ADVERTISING Kenya William Mutama, Fred Okoth, Frances Lagoussis (Mombasa), Trizah Njoroge, Herman Khayeri

According to a recent survey by Ernst & Young, 44 percent of business people in Africa identified inadequate infrastructure as one of the key constraints to doing business in the region. This is a clear indication that as Africa continues to grow, energy infrastructure development must top the investment agenda.

South Africa: Christine Tamukedde, Manoko Thosago, Prince Moyo Tabitha Muthoni,Winnie Sentabire, Angeline Ntobeng, Nqobile Ndlovu

As African economies undergo structural transformation from being primarily resource-driven to having bigger manufacturing and service sectors, general infrastructure development will be especially crucial. Energy development has not kept pace with rising demand, placing a large strain on the continent's existing resources. The World Bank has declared 25 of the 54 nations on the continent to be in energy crisis. According to the International Energy Agency (IEA), Africa will require more than US$300 billion in investment to achieve universal electricity access by 2030.

Construction of US$178 million US embassy starts

Benin

Construction of the new U.S embassy in Benin has commenced. The US$178 million multi-building complex is situated on an 8.8acre site along the Boulevard de la Marina and will include a chancery/office building, a support annex, a residence for the U.S. Marine detachment, a warehouse, a utility building, a recreational facility, and multiple access pavilions.

Once completed, the new complex will provide approximately 150 embassy employees with a secure, state-of-the-art, environmentally-sustainable workplace. The groundbreaking was presided over by U.S. Ambassador to Benin, Michael Raynor in the presence of the Benin Minister of Foreign Affairs, His Excellency Sir Nassirou Arifari Bako, representatives from other diplomatic missions in Benin, American officers and local authorities.

Speaking during the ceremony, Ambassador Raynor said that the new Embassy Compound will serve as a shining example of the excellent cooperation between the two countries. Also the projects will inject more than US$32million into the local economy, including the purchase of construction materials, the payment of wages and the cost of accommodation. The embassy will train 500 Beninese workers who will receive training in new construction techniques.

South Africa

The R1.6billion (US$102million) Portside development, currently under construction in Cape Town’s central business district, has been awarded a 5 Green Star office design rating by the Green Building Council of South Africa (GBCSA). The building is scheduled for completion in the first quarter of next year. The Old Mutual Life Assurance Company of South Africa and banking firm FirstRand Bank are the owners of Portside and it is the first tall building in the country to be GBCSA-certified.

It has 20 office levels, seven parking levels, four mixed-purpose levels and three basement levels, totaling 34 levels, with a combined 69 000 m2 gross floor area. Sustainability consultancy Agama Energy director, Mike Munnik, says one of the real benefits of pursuing a Green Star rating is the integrated approach to design challenges adding that there have been many meetings where problems were resolved by a design team rather than by individual disciplines. This contributed enormously to the successful outcome.

Both public and private sectors have to allocate scarce resources to construction, transportation, communications, energy and technology projects to achieve results under uncertainty and growing pressures of time, budget and quality.

In view of these scenarios, project risk management is an essential tool in increasing the chances of project success.Projects have become more sophisticated and complex over the years and this has uncovered unprecedented risk causes while amplifying risk impacts.

Mozambique Investment Summit Foreign investment into Mozambique is driving its economic growth. Predicted by the Economist magazine as one of the top 10 fastest growing economies in 2013, the country is offering the potential of high returns for investors. Large natural resource deposits from coal to gas are driving growth in sectors like real estate and infrastructure. With recent high profile financial losses for Mozambican projects, the question on all investors’ minds is how can risk here be mitigated and returns maximised?

LR 13000 With the LR 13000, the most powerful and tallest crawler crane in the world of conventional design, Liebherr is clearly extending its range of crawler cranes, steadily upwards. The most important area of operations for the new LR 13000 will be in the power station construction sector. With nuclear power stations of the latest generation in particular, the lifting of extremely heavy individual items is essential, while preassembled modules also have to be lifted as complete units, and that also drives the unit weights upwards.

But in refineries, too, there is an increasing demand for industrial columns weighing 1.500 tonnes and with lengths of 100 metres to be erected. Larger and larger cranes are also needed for the pre-assembly of offshore steel structures, such as oil platforms. The new LR 13000 from Liebherr is the only crawler crane in this size class which can work without derrick ballast. This is achieved by an extremely powerful slewing ring, developed and manufactured by Liebherr themselves.

National Housing Corporation to South Sudan’s tallest invest US$7.4million in housing scraper in the offing

sky Chinese company wins tender for NIB,NIC new headquarters

NHC Director General, Mr. Nehemiah Mchechu said once the three classic housing projects are finished they will host more than 3,000 people.

The 12-storey Equatoria Tower to be built in Juba will reportedly be South Sudan’s first modern serviced commercial building .

Ethiopia's NIB president, Ass. manager, China Railway No.3 Engineering Group and CEO , NIC during the tender signing ceremony.

Demand for housing in Tanzania has grown at an average of 200,000 housing units per annum and requires huge investments from both the public and private sectors to construct new units.

In efforts to meet the growing demand, the Tanzania National Housing Corporation (NHC) plans to invest TZS 124billion (US$7.4million) in three projects which will entail adding a total of 510 units in the housing market.

UAP Holdings Limited is planning to build the tallest commercial building in Juba, the capital city of South Sudan. The 12-storey Equatoria Tower will reportedly be South Sudan’s first modern serviced building offering amenities such as air conditioning, internet, three high speed elevators, water, electricity and sewage disposal.

The Nib International Bank S.C (NIB) and Nib Insurance Corporation S.C (NIC) have hired the China Railway No. 3 Engineering Group Co. Ltd for the construction of their 35-storey headquarters.

The design was completed two years ago, when the companies had only 2,800m2 of land.

NHC Director General, Mr. Nehemiah Mchechu said that once the three classic housing projects are finished they will host more than 3,000 people and will include commercial and recreational facilities. Mr. Mchechu made the remarks in Dar es Salaam after handing over sites to contractors who will implement the projects through the design-and build approach.

The NHC boss revealed that the firm it has plans for four other projects which will be much bigger, with 1,000 units. The projects that were handed over to the contractors recently include Golden Anniversary Towers located at the former UNICEF headquarters. It will have twin towers of 26 floors each.

The development, which will adopt green building standards, will be undertaken by UAP’s newly created South Sudan property company – UAP Properties Ltd (UAPL) at a cost of US$16.9 million. UAP has secured a US$5 million from the International Finance Corporation (IFC) of the World Bank to finance the project.

UAP Group Chairman, Joe Wanjui, said Equitoria Tower is a strong commitment by the UAP Group and its partners, Central Equitoria Investment Company with a 30 per cent shareholding, to development of infrastructure in South Sudan.

The development will contribute towards addressing the critical supply gap of high quality offices in South Sudan.

Transnet National Ports Authority signs MoU with Namport

Since then it has added an extra 882m2 plot and made changes to the original design. The construction will take place on this larger plot in front of Awash International Bank's twin buildings on Ras Abebe Aregay Street, in the area designated as the rising financial district of the city. The Chinese company was selected out of four that had responded to Nib's tender, announced on January 26, 2013.

The agreement was signed by Kibru Fondja, NIB Bank's president, Hailemariam Assefa, chief executive officer of the NIC, and Zhao Sanbao, the Ethiopian branch assistant manager of the Chinese company.Both parties declined to disclose the total estimated cost of the project, stating that it is too early to tell. However, according to, Tagel Nigatu, a project engineer at the Bank, construction of the building will cost an estimated 1 billion Birr (US$53million).

South Africa

South Africa’s Transnet National Ports Authority (TNPA) will be able to share technical expertise and help develop competitiveness of trade in the region after it signed a Memorandum of Understanding (MoU) with the Namibian Port Authority (Namport). This is the second in a number of memoranda TNPA intends to sign with ports in southern and eastern Africa. The first of these MoUs was signed with Maputo Port Development Corporation in June.

TNPA chief executive, Tau Morwe, said given the strategic similarities of their respective ports from a geographic perspective and the proximity to industrial zones they recognise the importance of improving their relationship and collaboration. Morwe said the collaboration is expected to result in the sharing of maritime experiences and exchange of technical expertise in relation to port management, port operations, port environment and security as well as training of employees.

The MoU entails sharing information in form of policies on a wide range of fields including infrastructure, development, improving the port environment and commercial waterfront development which will include trade and maritime services, the authority added.

Namibia’s first Green Star-rated Kazungula Bridge construction building in the offing gets underway

Mombasa’s second container terminal to be ready by 2016

The building will have six floors, including the ground level and six basement levels.

The bridge will replace the ferry that currently serves travellers between Zambia and Botswana.

The new terminal will have three berths with quay lengths of 230, 320 and 350 metres.

Namibia is to have its first independently certified Green Star building in the capital, Windhoek, with the construction of First National Bank Namibia’s (FNB Namibia’s) new head office. Namibia does not have a green building council and the bank worked with the South African and Australian councils to develop a rating system and terms of reference that apply to Namibian conditions.

The new head office will have a four stars rating.

The construction of the US$248 million Kazungula Bridge will infinitely improve the quality of life for the thousands of people who are currently reliant on a ferry to travel to and from Zambia and Botswana. GIBB’s Director, Electrical Engineering, Dr Willem Sprong, said schoolchildren and breadwinners are forced to wait a minimum of four hours to get across the bridge, but with the new bridge being developed, this would drastically improve access between the two countries.

Construction work at the second container terminal project, which is expected to enhance operations of the port of Mombasa is halfway complete. The terminal will expand the capacity of the Mombasa port to match future trends, stay competitive in cargo handling and facilitate economic development in the northern corridor.

The Kazungula Bridge is a bilateral trade tie between Botswana and Zambia. The bridge will be instrumental in aiding Botswana and Zambia to work together, increase trade and assist citizens’ work in either country without work permits.

Kenya Ports Authority (KPA) says the Ksh26 billion (US$297.2million) project is scheduled for completion by 2016 and it will add a capacity of 1.2 million twenty feet equivalent units (Teus) bringing the port’s total capacity to about 2.1 million Teus.

In April, the project had recorded 25 per cent progress, reclamation works and sand filling were at 30 per cent and 70 per cent respectively.

The project will see leading South African consulting engineering company, GIBB earn at least R40 million (US44million) through a joint venture with Nippon Koei, managing the review of the pre-construction phase and detailed designs, and ultimately, the construction. According to Dr Sprong, the Kazungula Bridge is a 960m bridge to be built over the next five years.

The project, which is being constructed at Kilindini Harbour on 100 hectares of reclaimed land, was launched last December by former President Mwai Kibaki. It will have three berths with quay lengths of 230, 320 and 350 metres. The larger berths will handle Panamax container ships of 20,000 DWT and Post Panamax vessels of 60,000 DWT.

Engineer Jackson Mubangizi President - Uganda Institution of professional engineers (UIPE) Engineer Jackson Mubangizi has been president of UIPE for three years. Formally, he was the Vice Chairman and honouree secretary of the Kampala branch. His responsibilities among other include directing the policy decisions of the institution, chairing and representing the institution at national, internationaland regional forums as well as providing guidance to government and other stake holders on engineering matters.

Engineer Jackson Mubangizi

Born on 17th May in 1971, Eng Jackson Mubangizi had his secondary education from Rukoni secondary school and Mbarara high school. He is a holder of a Master’s degree in business administration (MBA) and a Bachelor’s degree in Engineering-Mechanical from Makerere University Kampala. He has training in various fields like in quality management systems, environmental management system as well as occupational health and safety.

He is currently the Manager for the training and consultancy department at UNBS- Uganda National Bureau of standards, an institution with a mission to enhance national development through the application of standards in trade, industry and consumer protection. His roles include building capacity of the industry in implementation of standards through training and consultancy services.

Eng. Mubangizi has developed competencies in various projects and accumulated a lot of knowledge in management.

The blending of his engineering practise and standardisation sets him apart from other engineers.

10

Eng. Jackson Mubangizi was previously heading UNBS surveillance which was responsible for verification of goods for compliance to Ugandan standards. He was also in charge of the weights and measures department. His responsibilities included verification of weighing and measuring equipment for compliance standards.

Prior to that, Eng. Jackson Mubangizi was the Managing Director of “Med technologies Limited”, a construction company involved in supervision of construction works that also included gravity flow schemes, road works, fabrication of water tanks as well as construction of valley dams and distribution networks.

Eng.Mubangizi has developed competencies in various projects and accumulated a lot of knowledge in management. The blending of his engineering practise and standardisation sets him apart from other engineers. He aims to offer consultancies mainly in management engineering projects focusing on standardising services to create a competitive edge in organisations through credible management systems.

His view on Professionalism in the Construction Industry Eng Jackson Mubangizi says the construction industry in Uganda on a big percentage currently lacks professional engineers and this leads to substandard works in the industry. Many people choose to use non-professionals because they provide cheaper services. Nonetheless some industries do have professionals. It’s with this intent that UIPE was formed to provide professional engineers to fill the gaps. However absorption capacity of these professional engineers is still low in Uganda.

Uganda Institution of professional engineers(UIPE) The Uganda Institution of Professional Engineers (UIPE) was established as an association of Professional Engineers of Uganda in 1972. it was a successor to the defunct East Africa Institution of Engineers (EAIE), which had started in 1945.

The objectives and purposes of the Uganda Institution of Professional Engineers are to promote the general advancement of the science and practice of engineering and its applications, and to facilitate the exchange of information and ideas on those subjects amongst the members of the Institution. Current membership is of about 1500 members that include fellows, cooperate graduates, technologists, professional engineers, technicians among others. They also have student members whom they groom to become professional engineers in future.

UIPE also has graduate apprentice programs that focus on training graduate engineers aiming at fulfilment of registration requirements as engineers.

Challenges faced while training professional engineers Engineer JacksonMubangizi articulates that they have a problem of insufficient funds to train the engineers. Furthermore training in emerging areas like the oil industry are quite challenging because Uganda lacks Professionals in such fields thereby having no role models to inspire their professionals in training. More so, the public doesn’t demand for professional services quite often as they should which renders professionals out of work.

Lighting up Africa

By Emmanuel Onsomu lectrical power is a key ingredient for sustainable economic development not only for large industrial concerns but also for rural economic activity in the form of small cottage industries and agricultural development.

E

For too long energy in Africa has remained a scarce commodity with nearly 70 percent of its people lacking access to electricity and condemning many to live below the poverty line. Just to show how far behind Africa is, SubSaharan Africa, excluding South Africa, generates only 28 gigawatts of power, roughly equal to the generation capacity of Argentina.

A World Bank report has recently declared 25 of the 54 nations on the continent to be in energy crisis since energy development has not kept pace with rising demand, placing a huge strain on the continent's existing resources despite Africa having a feasible hydro potential of 1,750,000 GWh/year of which only 4.3 percent has been exploited to date.

There is no doubt that electrical power is essential if Africa is to emerge from under-development and take its place in the global economy.

This fact was further reaffirmed by the focus placed on the issue by President Obama’s recent trip to Africa in which he laid out his plan for boosting aid to Africa by promoting the electrification of countries in the continent. The plan seeks to develop up to 10 GW of electric power capacity — or 20 million households — in Africa.

The plan specifically names Ethiopia, Ghana, Kenya, Liberia, Nigeria and Tanzania.

October 2013

Hydroelectric power solution Hydroelectric offers a largely untapped source of energy in the middle of the continent. The Democratic Republic of the Congo, Cameroon, Ethiopia, Sudan, Nigeria, Guinea, Angola, and Mozambique all have significant hydroelectric resources, of which only 7 percent are presently developed. Of the 48 countries in Sub-Saharan Africa, 21 have a total generation capacity less than 200 megawatts. South Africa alone generates 45percent of the continental total, followed by the North African countries at 30 percent and the rest of the continent at 25 percent.

Of that energy, approximately a quarter is unavailable at any given time because of poor infrastructure reliability and insufficient capacity.

Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. Environmental concerns have seen the World Bank being skeptical in supporting huge hydro projects in the past. But this is not the case anymore. This is evident in the case of Inga falls project where it has shown interest in joining the African Development Bank and the Development Bank of Southern Africa in funding the project.

In the meantime, Chinese banks and construction companies have not been left behind. China Development Bank (CDB) has invested at least US$2.4billion in African infrastructure and commercial projects. There are also an estimated 800 Chinese corporations doing business in Africa, most of which are private companies investing in energy sectors to power and run their establishments.With financing unblocked, hydro power could be Africa’s way out of its predicament and proof of this is in the several projects that have been initiated.

Inga III DR Congo plans to build the Africa’s biggest hydroelectric project at the Inga falls on the Congo river in the Bas-Congo province, about 230 km downstream of Kinshasa. The first phase, dubbed Inga III, will on its own generate more power than Africa’s current largest hydroelectric-dam, the High Aswan on the Nile in Egypt.

According to the Congolese Minister of Water Resources and Electricity, Bruno Kapandji Kalala, construction works will take approximately six years. The project, the total cost of which is estimated by the AfDB at US$12 billion, would generate 4800 MW, more than half of which will be sold to South Africa.

Inga III, which is the first phase of the far more ambitious Grand Inga project, is one of the New Economic Partnership for African Development's (NEPAD) flagship projects. It will involve huge works. First of all, part of the flow will be diverted upstream of the existing Inga I (351 MW) and Inga II dams (1424 MW) to a presently dry valley which runs parallel to the Congo riverbed. Further phases would involve the construction of a dam

October 2013

which would entirely bar the course of the Congo River and divert most of the flow towards the Bundi valley and Inga III, whose 100 meter-high wall would enable the production of more electricity by additional turbines, up to 39,000 MW. The capacity of the project would be almost double what is currently the world's largest hydroelectric project, the Three Gorges dam on the Yangze Kiang River in China (22 500 MW).

The ultimate aim, according to AfDB plans, is to build interconnections or "power highways" from Inga across the entire continent - not only to Southern Africa but also to Egypt, Nigeria and Ethiopia which ranks second after the DRC in terms of African hydropower potential.

Ethiopia dam building program Elsewhere, Ethiopia has unveiled plans to invest in a new hydropower project in a bid to become an electricity powerhouse in the wider East African region. The country has contracted Italian engineering company ELC ElectroConsult to undertake prefeasibility and feasibility studies for the Tams hydropower project.

13

The project, the latest in a stream of mega hydropower projects the country is implementing, will have a capacity of 1, 060 MW. The planned Tams hydropower project will be built on the in the Baro-Akobo river, between the towns of Bonga and Gambella, some 766 km west of the capital, Addis Ababa. ELC ElectroConsult will partner with State-owned Water Works Design & Supervision Enterprise (WWDSE) to undertake the studies for the project.

ELC ElectroConsult, whose core activity is the study, design, construction and management of dams, hydraulic structures and hydro- electric and multipurpose projects, is not a newcomer in Ethiopia, having undertaken several projects, including the supervision of the Gilgel Gibe I and II hydroelectric projects. It is currently supervising the ongoing Gibe III and Grand Renaissance dam projects. The award of the contract came days after Ethiopia and Egypt settled a simmering confrontation over the 6,000MW, US$4.8billion Grand Renaissance dam, which is being constructed on the Nile River. Over the next decade, Ethiopia aims to invest a staggering US$12billion in power projects that will generate 20, 000 MW enabling the country to achieve energy sufficiency and export to neighbouring countries.

Kafue Gorge hydro power project In Zambia, ZESCO the country’s power utility has said it will invest part of the US$255 million Euro bond funds released by the government as seed money, to kick-start construction of the 750 MW Kafue Gorge lower hydro power project.

The company will use US$186 million out of 14

the US$255 million given by the government to embark on the long awaited project in Southern Province. Managing director, Cyprian Chitundu said the remainder of US$69 million would be used to finance work in progress aimed at improving power supply to residential areas. The Kafue Gorge lower hydro power project will be completed by 2017.

The Regional Rusumo Falls Hydroelectric Project The World Bank’s Board of Executive Directors has approved US$340 million funding for the 80MW hydroelectric project for the people in Burundi, Rwanda and Tanzania, as part of the Great Lakes regional initiative. The mega project to be undertaken in Rwanda is an 80 megawatt hydroelectric power station which will be in the Kagera River located at Rusumo Falls on the border with Tanzania, near the town of Rusumo, 117 kilometres southeast of Kigali, the capital and largest city in Rwanda.

Transmission lines will extend from the power station to Gitega in Burundi, Kigali in Rwanda and Nyakanazi in Tanzania. The Regional Rusumo Falls Hydroelectric Project, which has a total cost of US$468million aims to boost reliable power supply to the electricity grids of the three countries, reduce electricity costs and promote renewable power.

The Bui Dam In Ghana, the 400 MW Bui Hydro Electric Project is about 92 percent complete and in the final stages of construction. Dry and wet tests, which were to verify proper, complete and satisfactory erection

of all the subsystems for the first generating unit 3 were carried out and successfully completed in April 2013. The Bui Dam, cutting across the Black Volta, will be the second largest Hydro-electric project in Ghana.

Bujagali Hydropower Plant In October 2012, Uganda’s President, Yoweri Kaguta Museveni, inaugurated the 250MW Bujagali Hydropower Plant. The plant, constructed at a cost of approximately US$900 million, was jointly funded by Industrial Promotion Services (IPS), the infrastructure and industrial development arm of the Aga Khan Fund for Economic Development, Sithe Global Power LLC (USA), a company majority owned by Blackstone Capital Partners IV, L.P., a fund managed by Blackstone on behalf of its investors, and the Government of Uganda.

It has eliminated Uganda’s previous energy shortage by nearly doubling the country’s effective generation capacity (it currently meets 49 percent of the country’s energy requirements) and provides clean, reliable power at lower costs than existing power generating facilities. Construction of the plant commenced in August 2007. It comprises five units of 50MW each, commissioned in phases between February 2012 and June 2012.

Scaffolding and Formwork

By Yvonne Andiva and Torah Onyango wo items that you can be sure of finding in most construction sites are scaffolding and formwork. Scaffolding is an indispensible tool for improving safety for workers by providing easy and safe access while formwork is used as a mould within which to cast concrete. Both are popularly made of steel or aluminum and both improve conditions by reducing time by their ease of assembly.

T

Scaffolding basically consists of light weight tubes which are assembled alongside a structure in order to provide easy and safe access for workers. The tubes are usually made of steel or aluminum with varying lengths but with a standard diameter. Formwork on the other hand are also manufactured out of steel or aluminium and their modular design means that they can be easily

assembled in various shapes and sizes while the material used means that they have a long life cycle as compared to wood which can hardly be used more than once for this type of work. Various designs and the use of more innovative materials has meant that costs can be saved on site by using manufactured formwork and scaffolding and in this issue we take a look at what the market has to offer.

Pilosio S.p.A Pilosio is an important Italian company in the field of construction and maintenance equipment.

It was founded in 1961 as a manufacturer of scaffolds and formworks for above-ground walls, floors, ground containment systems, as well as equipment for both sale and rental. Moreover, Pilosio is specialized in the design, construction and sale of stage structures such as stage-boxes, platforms, coverings, and sound and video towers.

Pilosio is an international company: it is not only a significant presence nationally, but it is also strongly focused towards foreign markets, in particular North Africa, United States and Canada, South America, Middle East, Eastern Europe and Russia. The company registered a turnover of almost 40 million Euros and an export quota equivalent to 70 per cent, in 2012.

MP support structures Support structures made with components of the MP multidirectional scaffolding with a series of specific accessories for slabs, beams or any other item cast at height. Vertical elements and horizontal connections are made from elements

16

of MP scaffolding. The availability of numerous sizes of components enables the construction of structures of any dimensions. The tower with square base of 0.83x0.83 metres or 1.15x1.15 metres enables capacities up to 5 kN for individual vertical mounting for a total of 20 kN each tower.

The extreme modularity of this type of structure allows any construction site problems of capacity or geometry to be solved. It is possible to increase the capacity by doubling the uprights, to construct structures with a curvilinear or triangular base or any other shape to get around obstacles and even create supports for items with negative or positive inclinations. Using bases or adjustable brackets, the towers can also be used as temporary counterbalance for works to stabilize structures under construction. Service stairs can also be provided for easy access at height.

High capacity MP towers High capacity support structures for slabs, beams or any other item cast at height, constructed with components of MP multidirectional scaffolding combined with a series of specific accessories.

Each vertical element is made up of 4 MP uprights, interconnected by upper and lower scaffolding.

The elements made up in this way are connected four by four to form the tower. Capacity of the base module: 200 kN for each vertical element, equal to 800 kN for the entire tower. Higher capacities are possible but verification in advance is required with Pilosio’s technical office. For the construction of these high capacity support structures, all the October 2013

standard MP scaffolding components are used, combined with upper and lower scaffolding and adjustable screws. Vertical elements made up of 4 uprights have a wheelbase of 17x17cm and can be assembled into towers or walls of various dimensions, depending on the specific requirements. The great design flexibility and resistance of the MP multidirectional scaffolding combined with various accessories enable the construction of structures of any type, both for the support of horizontal planes, with shelves for the discharge of material, and formwork support structures for casting at height.

In this case, using bases or adjustable brackets, the towers can also be used as temporary counterbalance to stabilize structures under construction. Service stairs can be provided for easy access at height.

Meva Formwork Systems MEVA is an international formwork producer founded in 1970. The headquarters, research and development, engineering and production are located in Germany and serve some 30 countries across the world. MEVA provides formwork

systems and solutions for every application from hand-set formwork to climbing technology and from foundation to power plant for construction sites all over the world. All MEVA locations across the world are certified according to European standard DIN ISO 9001 and offer clients a consistently high quality.

Wall formwork MEVA’s wall formwork systems are modular and come with different panel sizes that can be freely combined vertically and horizontally. The hand-set, crane-independent systems are ideal when crane-time is limited or no crane is available or when site conditions are cramped. They are primarily used for small walls, foundations, residential and commercial construction.

The crane-dependent and heavy-duty wall formwork systems are used for large and high walls and structures such as big halls, power plants and infrastructure projects. MEVA’s Mammut 350 wall formwork handles concrete loads up to 100 kN and allows for an unlimited pour speed of up to 4 metres. Powerful support frames are available for single-sided applications, e.g. when pouring retaining walls against rock. MEVA’s largest support frame can be extended to heights over 12 metres. Rounded and polygonal walls, rectangular and circular columns can easily be formed using the MEVA formwork systems designed for such tasks. The circular formwork can be combined with wall formwork to pour walls with rounded end.

Slab formwork MEVA’s conventional slab system consists of few parts and can be used with a facing of the user’s choice. This low-cost system is ideal for irregular slabs and for few yet large-size applications.

Fire fighting

and prevention technologies

By Torah Onyango and Yvonne Andiva ires are a leading cause of injury and deaths not to mention the loss of property that runs into the millions every year. The greatest tragedy in most cases is the fact that most fires can be prevented by taking fire regulations seriously and installing reliable fire alarms and firefighting equipment in buildings. There are three elements needed to start and sustain a fire and/or flame.

F

These elements are a reducing agent, an oxidizing agent and heat. When these elements work in tandem then the result is a destructive roaring fire. Fire alarms play a crucial part in providing early warning in order to galvanize evacuation of buildings and alert fire fighting departments. Once a fire has started, containment is key and this includes containing the associated smoke.

Today buildings can be equipped with fire resistant and fire retardant materials in the form of paints and boards. Every minute counts and can make the difference between saving a life or not so these materials can be very handy.

Fighting the fire requires specialized equipment.

Building codes require the installation of fire hoses as well as fire extinguishers to fight fires. Their purchase and installation is crucial because faulty equipment can be a very costly flaw.

Fireguard Safety Equipment Co Ltd. Fireguard provides the most advanced automatic kitchen fire detection, fire suppression and monitoring system in the world. It comes with optional wireless monitoring which can remotely shut off the power to the cooking equipment.

Fireguard provides a complete Fire Suppression system that can be used from small mobile cooking units up to the largest catering kitchens, factories with cooking/frying process's and domestic cooker hoods . The Fireguard K2 fire fighting agent has been developed with support 20

from their sophisticated R&D partners over years of extensive research, ensuring the rapid and total extinguishing of flames and cooling of the oil and surrounding area to help prevent re-ignition. The K2 Fire fighting agent has a low pH value of 8 and will not harm the stainless steel surfaces. After discharge the system can be quickly cleaned, reset and the kitchen is operational again within a few hours. The fireguard kitchen hood system offers total flexibility of installation, and can be incorporated into any existing kitchen with a minimum amount of disruption and delay.

New equipment can be pre-engineered during manufacturing to incorporate the fire protection system which can be professionally fitted with any kitchen hood. The agent cylinders are stainless steel which meets EN3 specification, tested to 391 PSI. The discharge valve assembly is fully factory charged with air/nitrogen and pressurized to 1,740 PSI. The brand ‘Fireguard’ is a symbol of quality, reliability and efficiency of their products.

HVAC

systems for comfort

By Yvonne Andiva and Eric Mongare VAC systems have become an essential component of any building or industrial facility. The three components of heat, ventilation and air conditioning as found in the acronym HVAC need to be carefully considered to ensure the right system is installed. They are key in ensuring the provision of thermal comfort and acceptable indoor air quality. When installing a new system the cost of installation, operation and maintenance will be the overarching objective for any owner and so careful examination of what is in the market is essential.

H

Equipment suppliers today focus on providing system designs that offer greater efficiency in the use of energy, take up less space, make less noise and are more cost effective to run. As the drive towards “green building” takes hold, optimization of the use of space and resources has become all the more important. Building automation has also caught on as a trend and here too HVAC systems require offering open system solutions that facilitate the integration into buildings other systems.

Staff Jatinder has put together a dynamic team of talented professionals to pursue groundbreaking designs and planning schemes in Kenya and the rest of the region. Jatinder himself oversees the architectural/planning side while Sandeep Thethy takes charge of Interior Design.

The dynamic pair is backed by a team of 3 registered architects, 2 graduate architects, 7 technicians, 2 interns and support staff.

the following year to establish his own practice, Innovative Planning and Design Consultants.

Projects IPDC’s first project was One Riverside Drive, a high end luxury apartment complex in Westlands, Nairobi. The development combines world class architecture with the finest interior design to give residents every conceivable luxury. According to Mr. Simon Ngaruiya, who is in charge of Finance and Administration at IPDC, this project thrust IPDC into the limelight and established the firm on a solid trajectory to greater heights.

The client, AMS Properties, was extremely pleased as were industry observers. Indeed, notes Mr. Ngaruiya, the developer was able to sell the apartments off plan based on the indicated designs and finishes. Subsequent projects by IPDC were also a success. One Riverside Drive was quickly followed by others such as Fortis Tower a cleverly designed and aesthetically pleasing office complex and One West Park, a premier high end residential apartment complex that is sure to take some awards in the near future, selling 80percent off plan. On the residential front, IPDC was also selected to undertake Fivestar Meadows (see CR June 2013 issue). The development, on Kiambu Road near Nairobi, consists of 116 Spanish-style

villas (with an independent DSQ), comprising three and four bedrooms. These have showcased a consistent standard of clever design approaches

by IPDC and have also performed extremely well in sales.

Another large scale residential project was Delta Plains near Athi River. This project, developed

by Delta Corporation, consisted of 154 three and four bedroom maisonettes in a gated community concept. The estate, completed in 2012, features a water treatment plant and borehole, generator for common areas, gymnasium and a mini shopping centre among others.

Other projects handled by IPDC include up market apartments by Trident Estates and Nairobi Sports House in Nairobi and the brand new Leopard Beach Resort and Spa Residences Scheme on the famous Diani Beach along the Kenyan coast. The firm has also designed apartments in Kampala, Uganda, and submitted proposals for developments in Rwanda and Burundi.

Competitive Edge “Impressive designs and superb finishes are some of the elements that set us apart from the others”, says Mr. Ngaruiya, noting that IPDC architects are particularly attentive to detail and engage with

Finally, some clients are unwilling to pay even after services have been rendered. Others want to pay less than what is provided in the fees schedule.

Still, other clients pay but do so after huge delays.

“Regardless of these difficulties, we as a firm have to conduct ourselves professionally”, says Mr Ngaruiya. “We cannot abandon a project or compromise on quality”.

Future According to Mr. Ngaruiya, in the next 5to 10 years, IPDC would like to be considered amongst the top Architectural firms in Africa and with recognition on a global scene through International Awards.

Considering what the firm has achieved in the five short years it has been in existence, this does not sound like an unattainable goal. The firm certainly looks set to play a major role in the development of the exciting property scene in Kenya and beyond.

Challenges Like any other consultancy, IPDC faces several challenges. “Sometimes”, says Mr. Ngaruiya, “clients request for design proposals and then do not turn up to discuss the implementation of the proposed project”. He says that many claim they are in the process of looking for funds from banks or other sources. Another challenge is encountered in dealing with contractors. Since the client expects his project to run on time, within budget and in adherence to quality requirements, the architect has to keep contactors on their toes to ensure that this is achieved.

Daykio Office Suites

I

n recent years, more organizations in Nairobi have been seeking office space away from the Central Business District in order to escape from perennial traffic congestion, shortage of parking space and noise pollution. It is these kinds of problems that Daykio office complex aims to alleviate. Located along Ngong Road, Daykio is a modern 7-storied office block with all the amenities needed to create an ideal environment for office work.

Project background The project architects, Aaki Consultants Architects & Urban Designers, were commissioned by the client, Daykio Plantations, to develop a high end quality office building with ideal sustainable environmental strategies for quality commercial and office space.

Form The building has adopted a cuboid form with creatively accentuated curvilinear elements and interplay of rectilinear recesses, creating a visually 28

captivating building. The use of a near square layout facilitates maximum utility of space to the advantage of the end user. Use of framed curtain walls lends to the visual verticality of the form.

Extensive use of solar glass and double glazed ventilated facades ensures a cool interior office space on the eastern and western facing façades.

Provision of a centralized sky lit atrium space in the lift lobby ensures that there is continuous flow of clean air into the office spaces as well as adequate natural lighting.

Spatial layout The design centralizes the service core which reduces circulation area and subsequently maximizes office space. The service core opens up into the atrium facilitating natural ventilation and day-lighting. It is not lost on the developers and the project team that today’s office occupant wants his freedom to customize his working space.

This is the reason why Daykio has built into its design the following salient features: Flexible selfcontained office suites, Option to have executive

private toilet and kitchenette, Ample office space, Fibre optic link, Full ICT backbone , High Quality finishes in common areas and Fire detectors.

Green energy conservation approach to design In line with the need for environmental conservation and energy efficiency, the design has incorporated various eco-friendly considerations.

These include the following: Solar glass windows, Double glazing with outer frameless solar curtain glazing on east and west facades , Location of services on the eastern and western facades, Expansive roof to shield upper floor from direct sunshine,Atrium with skylight for ventilation and natural lighting and Landscaping to add to visual value and quality of building site Building Materials All through the various stages of development and construction, only the most sophisticated building materials were utilized. This means that the office block will boast of the feeling of accomplishment October 2013

HEADER

Other design highlights The unique low-rise office development offers a wide range of facilities to increase value to potential users. The building will have a beautifully landscaped compound, which will serve to accentuate the built form as well as reduce direct insolation on the building. A high parking ratio of one car for every 55m2 will ensure adequate parking of up to 100 cars for unit owners/tenants and visitors. Due to the inconsistent water supply and occasional electricity supply problems experienced in Nairobi, a standby generator, and underground water storage were factored and provided for during the design stage of the Daykio offices.

In light of advances in the ICT sector and fast growth of e-business services, accommodations for a fast fibre optic link as well as a full ICT backbone (for data/power/voice) were catered for early in the design stages to increase value for potential users. IT/ Telecommunications ducts as well as a communication mast for satellite dishes have been provided to cater for this.

The service core areas/lobbies with granite and Granito tile finishes provides easy access to the common toilet facilities for visitors and staff on all floors. Firefighting sprinklers in the basement and covered ground floor parking ensure that any fires that break out in these spaces are quickly put out, minimizing potential damage to vehicles parked in these spaces. for every occupant. The various areas will be created with just the right material, making Daykio, a place that one would want to operate from.

A walk through will give an idea of what to expect: The lobby floors feature granitofloor tiles. This complements the granite cladding of the lobby walls and kitchenette areas. The ceiling in the lobby areas is acoustic. To ensure that minimum maintenance is required externally, in addition to giving the building a bold visual impact, mammoran render with bold colours is used with the Alucobond cladding.

The combination gives the building a unique and more enhanced visual character. The office spaces will be finished with floor screeding. This is designed to allow end users, room to use own desired floor finish. The lower basement walling and boundary walls feature Mazeras cladding.

Other Facilities Daykio is a development designed for continuous occupation. This means that all necessary amenities have been installed for the comfort and convenience of the occupants at all times.

Installed facilities include: 375KVastandby October 2013

generator, Basement water tanks for fire fighting and potable use,Roof top tanks for portable water, Fire emergency response utilities including: portable fire extinguisher, dry risers and hose reels, sprinkler systems in basement and podium parking and pressurized fire escape, Full ICT backbone and CCTV surveillance for enhanced security.

Project Challenges Daykio Office Block development has faced a few challenges along the way. The main ones have been the run away inflation and high interest rates. These have had a negative effect with local commodity costs going up. This is, however, stabilizing and the project is expected to be completed as per schedule.

South Africa If you live in Africa, you will know a roof is not just about completing a design; it is your first level of protection from a harsh and sometimes extreme climate. Incessant rains, high winds, baking sun and hail batter outer shells of buildings threatening their integrity. The solution according to painting, waterproofing and construction company, Indawo, lies in paying attention to roofing and waterproofing to safeguard buildings. Indawo managing director, Geoffrey Jäck, says roofing structures have to be sound and built strictly to specifications with a complete understanding of the risks buildings face.

Waterproofing solutions Jack adds that waterproofing solutions are tailored for the specific roof design Flat roofs need more complex solutions than steep pitch roofs and outer structures always need to be protected to avoid water ingress. On top of this, areas exposed to rain and fluctuations in temperatures, must be waterproofed and painted using a skilled 42

workforce and the right products to provide the necessary guarantees. The perseverance of water in its efforts to find a point of ingress is startling.

Water will find the path of least resistance and slowly make its way through roofs and down walls. The damage, even in the short term, can be devastating resulting in costly repairs, over and above the damage to furnishings and fittings inside buildings. Long-term damage can even condemn a building. Jäck recommends a structured preventive maintenance plan. With the assistance of waterproofing professionals, identify areas on the roof and outer structures that may be prone to water damage, he says.

A short-term plan can address areas of weakness and a longer-term maintenance strategy ensures consistent checking of the exterior of the building.

This strategy should include a component that addresses ongoing maintenance needs like painting, wood and decking protection and proper installation of substructures when needed.

Indawo recommends continued monitoring of the following: Roof and roof edges; A roof has to be watertight and this should never be compromised. Full protection is needed around flashings, gutters and all the way to the edges. Any breach in the waterproofing will allow for water ingress and threaten the integrity of the building’s protective functioning. Check for discolouration, cracks, peeling or damp. Water damage; Locating causes can be complicated. It is not always evident and can be several metres from where the damage manifests. You can follow the evidence, tracing telltale signs but even this may not lead you to a cause.Small pools on a roof should be checked and the area repaired to provide run-off. Roofing and gutter screws are ideal spots for water to penetrate.

Stains on ceilings indicate water damage while mould may just be the cause of insufficient ventilation. If you are unsure, call in waterproofers.

South Africa Roof weaknesses;Today there are many roofing materials and waterproofing systems available.

Asphalt can erode and move in regions where there are extreme fluctuations in temperatures.

Tiles break, roof sheeting rusts, asbestos is dangerous, technological advanced membranes can be damaged when installing substructures, and the list goes on. Jäck concludes that managed maintenance is critical to ensure the safety of your building and guarantees positive returns on investment,. A maintenance strategy is an owner’s commitment to the protection of this investment.

Avoid water related damage by protecting against it

natural green spaces in built up areas, hold grounds for gardening, food production and horticultural therapy, and increase passive recreational space in densely-populated neighborhoods.

Green Roofs Green roof refers to a system of roofing that is completely covered with vegetation. The revival of green roofing dates back to the 1960’s but only in recent years has it become a popular alternative to the traditional roofing due to its substantial environmental benefits and savings for heating and cooling. Green roofing is a traditional method that originated in northern countries like Iceland and Scandinavia and was used for its insulating capabilities. Green roofs hold the potential to mitigate impacts on stormwater quality and quantity, improve building’s energy efficiency, reduce the urban heat island effect, improve air quality and additionally, beautify the city, provide

Green roofs have urban agriculture potential Many people take advantage of the possibility to grow their own fruits and vegetables on rooftops adding to urban food security. Rooftops as urban agriculture spaces also have many social, economic and health benefits for a community that currently is virtually non-existent in most South African cities, although many cities around the world have realised the value and need for such initiatives and encourage them as a means of sustainable food security for urban populations.

Community run urban agriculture programs have far reaching benefits as they empower groups to be self-sustaining and less vulnerable

Green roofs improves air quality Green roofing has become increasingly popular in cities because it creates additional green spaces that absorb carbon dioxide and other chemicals and dust particles that pollute the air. Green roofs have the potential to bring the carbon cycle within urban areas back into equilibrium because of their ability to absorb carbondioxide and release oxygen into the atmosphere.

Tensile Fabric Structures

Practical aspects of design and material specifications South Africa

Dr Ken Price, BSc (Hons), DIC, PhD, FIStructE, FICE, PrEng, CEng - Director, Tension Structures, Cape Town Concept design and criteria for shape finding The concept design is the most important stage of the design process – a bad concept will reverberate throughout the design, manufacture and installation process, and will impair the appearance and performance of the final product. A number of factors need to be taken into consideration, including, but not necessarily limited to, the following: • Geometric constraints of the site and adjacent buildings • Sun shading levels required & sun angles • Air flow & ventilation of the space • Light transmission requirements for the

• • • • • • •

space below Availability & positions of anchorage points Need for continuously sealed perimeter anchorages Aesthetic considerations & compatibility with adjacent elements Achievement of adequate curvature to minimise fabric stresses &movements Drainage of rainwater & avoidance of ponding Suitable fabric slopes to ensure adequate self-cleansing Nature of supporting structure & tensile elements

Methods used for concept design • Wire frame computer models – these simple computer models are the starting point for investigatingvarious fabric forms and developing the concept design into a practical form toensure that the design criteria are satisfied.

• Fully rendered computer models –models of the final design of the fabric structure can be added to the model of the whole building, and are thus very useful for final presentations to clients.

Anchors, foundations and supporting structures The provision of adequate anchorages and supporting structures must be addressed at the earliest stages of the design process. Failure to address these issues early on could result in the tensile structures being impossible to include once the design and construction has progressed beyond a certain stage.

Even small canopy structures impose significant forces on the sub-structures, and large structures will require special design features to be able to resist the tensile forces. Tensile fabric structures impose forces which have significant horizontal and vertically upward components, and these are not the types of forces which buildings are normally designed for. If special provision has not been made for these forces, it is crucial that the tensile structure be designed taking this into account.

PVC/Polyester fabric – properties & characteristics PVC/Polyester fabric consists of a woven polyester base cloth, which is then coated with PVC and another top coating. They can be classified into 2 basic categories, depending on the type of protective top coating, as follows: a) Acrylic lacquer b) PVDF/acrylic lacquer alloy coatings in varying proportions

Factors influencing fabric performance Observation of fabric structures in different situations in various parts of the world show that the particular environment in which the fabric is situated has a very significant effect on its performance.

These top coatings have a large influence on the performance and appearance of the fabric, because they not only provide the fabric with some of its UV resistance, but they also vastly improve its self-cleaning characteristics.

In general, fabrics with acrylic coatings have not performed that well long term in tropical countries,

and most examples appear to attract and retain significant amounts of dirt and dust after relatively short times in service. On sites with high UV levels, the acrylic coatings break down fairly quickly, and thus the deterioration in appearance can occur within a few years after installation.

If the humidity levels are high, the deterioration in appearance can be even worse, as black mould growth can occur within the fibres soon after the coating breaks down. The fabrics with PVDF/ acrylicalloy coatings are the most commonly used, and have now been in service about 25 years.

The PVDF/acrylic coating is heat fused onto the base fabric as part of the manufacturing process.

The top surface of the fabric has a smooth slippery feel to it, and it is thus very effective in repelling dirt and resisting mould growth.

The main factors which appear to influence the fabric performance are the following: • Geographic latitude and thus the temperature of the fabric • UV radiation level reaching the fabric • Humidity level • Pollution level, as well as the type of pollutants • Dust level • Frequency and nature of cleaning operations • Deposition of vegetable matter (leaves, etc.) onto the fabric • Staining resulting from rainwater run-off over other building materials • Exposure to direct rainfall to assist in dirt and dust removal The effect of items a) to e) cannot be influenced by the designers, contractors or owners, but items f) to i) should be assessed by the design team.

Fabric options –PVC and PTFE There are basically two generic types of fabric which are commonly used for permanent outdoor structures, i.e. PVC coated polyester and PTFE coated fibreglass.Both of these fabrics are available in various types of mesh format. For short term and interior structures, many more options are available, including various types of cotton and other synthetic materials, including stretch fabrics such as Lycra or Spandex.

result in significant cost savings on lighting. Fabric is also very effective in reducing the transmission of radiant heat from the sun, and it is a material which has been significantly underutilised in the climatic conditions prevailing in South Africa.

However, global warming is likely to result in increased usage of tensilefabric structures in future.

Useful lives of 15 - 25 years are achieved with these fabrics, with the anticipated life being directly proportional to the amount of PVDF in the top coating.

PTFE / Fibreglass fabric – properties & characteristics The first outdoor PTFE/fibreglass structure was erected in California, USA40 years ago and is still performing well in service. It is therefore likely that structures which are made with today's PTFE/fibreglass fabrics will achieve useful lives in excess of 50 years.PTFE/fibreglass fabric is very effective in repelling dirt and some structures which have been inspected after years in service have perfectly clean surfaces even though they have never had cleaning maintenance.

South Africa

Three of the new stadiums built for the Soccer World Cup in South Africa in 2010 had PTFE/ fibreglass roofs, but the main disadvantage of PTFE fabric is its high cost – the overall cost of structures using this fabric are almost twice that of PVC structures.

Light and heat transmission One of the main advantages of fabric is its translucent properties – on average, architectural fabrics transmit about 13% of the light falling on the top surface. This results in a very pleasant light and airy feel to the space below, and can also

50

Lighting of fabric Lighting is very effective in emphasising the aesthetic appearance of fabric structures and should always be included whenever possible.

Both back-lighting and front lighting can be used depending on the effect that is desired.

Fabric and fire PVC has fire retardant properties, and achieves a class 2 fire rating – meaning that the fabric is self-extinguishing and does not produce drips of molten fabric. This fire rating is generally accepted by most approval authorities for use as a roof enclosure. PVC has an added advantage in a fire situation in that the fabric seams will separate at about 100ºC, thus allowing the very early venting of toxic fumes and smoke. This is a major advantage in saving lives of people who may be trapped in the building.

Cleaning fabric Fabric is easy to clean and can be done using similar methods to those that one would use to clean a car, i.e. soft brushes, light duty, non-acidic detergents and copious rinsing water. Personnel can access the fabric by means of ropes and use soft soled shoes to walk on the fabric.

Structural materials – choices for tensile structures All the usual structural materials (steel, concrete, aluminium, composites, etc.) have been used for tensile structures, but generally the emphasis is

on the achievement of a minimalist appearance for the supporting structures. As steel has the highest strength and stiffness values, and is also relatively cheap, it is the most commonly used material.

Tensile systems – design & materials The choice and design of the tensile systems is one of the most important aspects of tensile fabric structures. A variety of materials and coatings are available, ranging from marine grade 316 stainless steel, through hot-dip galvanised steel, to simple painted steel. The particular environment in which the structure is sited is of prime importance in selecting the materials to be used, because the tensile components are generally fully exposed to the vagaries of the weather. Unfortunately, there are numerous examples of inadequately specified materials being used for short term cost benefits.

The design and selection of tensile connections is an area which requires specialist expertise and this work should not be undertaken without adequate engineering experience and knowledge.

The main aspect of the design which requires careful attention is the secondary effects - these often have a major bearing on the performance of the components in practice.

Local wind load effects, eccentricities, unequal load sharing in multiple connections, angular discontinuities (resulting in bending stresses), fatigue loading, etc. need to be taken account of. The visual impact of these connections on the overall appearance of the structure is significant and due attention needs to be given to ensuring that they contribute to enhancing the inherent aesthetic appeal of tensile structures.

From conception to breathtaking structures

Conception Tension Structures engineers work hand in hand with architects and designers to develop a design concept into a photo realistic 3-D model for complete visualisation. This ensures that designs not only meet aesthetic intent, but are structurally stable and functional. All projects are signed off by professional engineers who specialise exclusively in the design of tensile structures. The end result is a set of all inclusive design drawings, from foundations to steel and cable elements and finally fabric.

October 2013

Manufacturing Tension Structures only use fabric from the best international manufacturers. These fabrics allow for control of light intensities, provide wind, rain and solar protection and also have appropriate fire retardant proprieties. Endless fabric forms are possible.

The backbone of these structures comes from structural steel and cable systems, with cables and fittings usually being made from marine grade 316 Stainless Steel to ensure the longest possible lifespan.

Steelwork components are manufactured from hot-dip galvanised steel, coated with twopart epoxy coat paint to combat the corrosive environments which exist around the coast, and in polluted urban situations. Tension Structures take great care to ensure that the designs of steel and cable connections are cost effective, aesthetically

pleasing and functional.

Fruition Following a rigorously planned installation process, using stringent quality control and safety measures, the majestic structure unfurls into a multifaceted and functional masterpiece.

The tensile structure transforms the architecture and elongates and elevates the walls into the space beyond. Entrust your fabric architecture to the expertise of the Tension Structures team and work with us to create magic. If you would like any further information, please contact us.

VOID FORMERS AND PILE CASINGS Development The Superlite Void Former has been developed to provide the South African construction industry with a low cost, lightweight and robust cell former. They are designed to meet the stringent performance requirements imposed by local design and on-site conditions. They are spirally locked, seamed and swaged for maximum strength and resist the full hydrostatic pressure of concrete and all loads associated with the compaction or vibration of concrete during placing.

Product Characteristics Superlite cell formers are available in uncoated or galvanised mild steel. Standard material thicknesses are 0,6; 0,8; 1,0 and 1,2 mm but other thicknesses can be catered for if the need arises. The standard maximum length of the cell former is 6 m, but special longer lengths are available on request. Where extra long lengths are required, the cell formers may be supplied in split lengths and ďŹ tted with a system of spigot and socket joining collars to enable the contractor to achieve any length that may be required.

Stop ends can be provided if required to prevent the ingress of concrete, if the cell is to be used as a void former. Timber braces can be provided to minimise the risk of distortion during transport action especially where long distances are involved.
