China’s influence as a global player has continued to rise in the past two decade or so , moving in tandem with its economic might.

CHIEF DESIGNER Simon Muhia

In Africa the Chinese have taken special interest in the acquisition of mineral resources in order to feed its industrial consumption.

WEB / GRAPHIC DESIGN Augustine O. Ombwa

In the construction industry Chinese companies have also made significant inroads in virtually every country outside South Africa edging out traditional European and South African companies. This has been in part attributed to cost competitiveness, access to cheap capital and skilled low cost labour. The Chinese’s government has also lent support in this endeavour.

While there was a time their quality was called to question today, the quality standards have been anything but poor and so despite Africa’s challenging environment the Chinese are coming out on top when it comes to large infrastructural and housing projects.

Uganda: Penny Komugisha, Betty Nabakooza Botswana: Dickson Manyudza, Gerald Mazikana Tanzania: Tom Kiage

Its time for the indigenous companies to borrow a leaf and evolve, strip off excess fat and become more competitive in the changing environment otherwise they will soon become a relic of the past.

Uganda

Bujagali Adds 250MW to National Grid The multi-million dollar Bujagali hydropower project has finally achieved and exceeded the 250MW contracted capacity, which has been added onto the national grid for consumption. This development means Uganda can meet her electricity needs for at least two years from now. "There is no more load-shedding whatsoever because all the machines are running," energy minister Irene Muloni confirmed. Bujagali Energy Ltd announced the successful completion of the mandatory seven-day reliability test run for the fifth unit. Unit four was commissioned two weeks ago. Consumers will not experience loadshedding 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 ministry's strategic decision to replace the expensive thermal power generation at the earliest date and minimise load-shedding

No more load shedding as 250MW is added to the national grid.

Kenya

Petrocity Unveils Sh1.5 billion Oil Terminal The entry of more private players in the construction of oil terminals will lead to reduced fuel prices for motorists, an industry expert has revealed. Petrocity Managing Director Aman Kurji said that a key factor in determining the price of fuel by the Energy Regulatory Commission (ERC) is the trucking costs incurred during the transport of products from Mombasa to Nairobi and the demurrages caused when vessels have to wait at the port due to lack of space at the Kenya Pipeline Company (KPC) depot. He spoke while unveiling a Sh1.5 billion terminal which is to be located in Konza on the Nairobi-Mombasa highway. The facility, whose construction began in January, is about 50 percent complete as they plan to cater for Nairobi's growing demand for fuel by increasing availability of petroleum products to new entrants and independent dealers who have limited access to truck loading facilities in Nairobi. Petrocity will have a highly advanced stock controlling computerised system set up by the major American conglomerate company Honeywell, to provide oil marketers with live and up-to-date stock positions instantly. The complete package to be supplied by Honeywell includes the pipeline receipt system, tank farm, truck loading system and terminal automation.

Oil terminal nears completion. There are hopes it will result in reduced pump prices.

Dangote Resume Construction of U.S.$115 Million Cement Plant in Cameroon The construction of Nigerian cement giant, Dangote Cement Plc's $115 million (N18.2 billion) new plant in the Cameroonian economic hub of Douala has restarted after a land dispute was resolved. Work on the 1.5 million tonnes-a-year plant began last September and was due to last 18 months. But it was halted earlier this year after the ethnic Sawa people filed an injunction against the project, complaining it violated their sacred site on the banks of the Wouri River. "Following instructions from the Presidency of the Republic, work has resumed at the Dangote cement factory," the Governor of the Littoral Region, Joseph Beti Assomo said.Sawa representatives were not immediately available for comment but several Douala residents confirmed that construction work was on going. Nigerian billionaire Aliko Dangote is aiming for a valuation of up to $40 billion for his rapidly expanding cement company at its London listing next year, several times that of top global rival Lafarge.

Dangote's Cameroonnian project back on track after delays due to a land dispute.

Egypt

Work underway at Damietta power plant Work is underway to expand the Demietta power plant after a long record of facilities mismanagement, poor working conditions and disputes between residents and employees against its management, the State Information Service reported recently. The power plant was labeled by residents as the most hazardous plant in Egypt. However work is underway at the Damietta power plant at a cost of around EGP2bn, said Egypt's Electricity Minister Hassan Younis. The 500-megawatt power plant consists of three steam turbines using natural gas as primary fuel and diesel as alternative. It is expected to be operational by May of 2016. The scheduled expansion of the plant was an attempt to rectify the plant’s waste management problem though Protesters demanded that governorate officials shut down the factory, which they said was “deadly and hazardous” to residents, marine life, as well as agriculture. Residents also said the factory, which produces fertilizers and petrochemical products, did not use proper filters when disposing its waste, which has been Damietta power plant has revived at a cost of EGP2bn. disastrous to the environmental integrity of the governorate.

Ivory Coast to triple capacity at main port

Ivory Coast

Ivory Coast's main port of Abidjan aims to nearly triple annual container capacity to 2.3 million units by 2016 to keep up with regional competitors following a decade of neglect, the port's director said. The port authority opened bidding for the construction and management of a second container terminal recently. The planned second terminal will have a transit capacity of 1.5 million 20-foot containers per year, adding to the port's current capacity of 800,000 containers. Construction will begin next year, with completion expected in 2016, Sie said. The port, located in the West African nation's commercial capital, is already one of the region's principal shipping hubs. The bulk of top grower Ivory Coast's cocoa exports passes through Abidjan, as do around 60 percent of goods entering and exiting land-locked Mali, Burkina Faso and Niger. A political gridlock ended last year after a brief civil war, and Ivory Coast's economy is rebounding. After a contraction of 4.7 percent in 2011, the IMF is projecting GDP growth of 8 percent this year due largely to a series of major public works projects.

Bayelsa Releases US$37 million for Road Projects

The port authority has opened bidding for the construction and managment of a second container terminal.

Nigeria

The Bayelsa Government in Nigeria has promised to resuscitate the abandoned three senatorial roads with the release of N6 billion to three construction firms for the speedy completion of the projects, with a view to fast track development in the hinterland. Presenting the cheques at Government House, Yanagoa, Governor Seriake Dickson urged the construction firms, to ensure they deliver quality job, taking into cognizance specification and concept of the road projects. A breakdown of the funds released shows that N2 billion was for the construction of Yenagoa-Oporoma Road by Julius Berger, representing the Central Senatorial road project; N2.5 billion for the construction of Sagbama-Ekeremor Road in the West Senatorial district road to Setraco and N1.5 billion to China Construction Company for the execution of Etegwe -Tombia Road. 8

Oman

Construction of an Independent Water Project (IWP) in Muscat set to begin The project will be constructed within the complex of the existing Al Ghubrah Power Generation and Water Desalination Plant in Muscat Governorate. The latter facility, built in phases over many years, is itself planned to be decommissioned in line with OPWP’s seven-year planning process, as well as for environmental considerations. Of nearly 15 international companies that had sought to prequalify to participate in the competitive tender for the licence, seven leading developers were invited by the Tender Board to submit their proposals for the IWP.

Marubeni Corporation has joined hands with the wholly Omani governmentowned energy and infrastructure investment vehicle, Oman Oil Company and National Power and Water, to bid for the IWP licence. JGC Corporation of Japan has signed on as the Engineering-Procurement-Construction (EPC) contractor in the bid.Malakoff International has teamed up with Sumitomo Corporation along with Spain’s Cadagua, a leading engineering and construction firm specialising in the establishment of water desalination 15 international companies had sought to prequalify to participate in the competitive tender for the licence. plants.

Africa

U.S.$851 Billion Annually for Infrastructure' Developed and others emerging nations will need a total investment of $851 billion annual to enable them improve on the quality of infrastructure in their economies, the global strategy and consulting firm - the Roland Berger Strategy Consultants has said. The infrastructural facilities include water, electricity supply, telecommunications or transportation. According to Roland Berger, there are 145 countries with low to moderate gross national incomes that need to invest the above mentioned amount annually to bring their infrastructure up to date. It insisted that lack of infrastructure meant that some countries were producing less than 45 per cent of their capacity, adding that there were risks associated with the poor state of infrastructure in those countries. These risks are often misunderstood, and should be accorded a considerably lower interest rate risk surcharge than the norm. These improperly assessed risks are costing Africa alone around $9 billion per year. For this reason, some countries today are only half as productive as they actually could be.

Infrastructure development in Africa requires U.S.$851 Billion annually to meet demand.

New Technique Allows Mass Production of Building Components Like other professionals, architects have used computer-aided design (CAD) software in their work for decades. Typically, the resulting digital files are converted to hard-copy plans, which are then used to support traditional construction practices. Researchers in the College of Architecture at the Georgia Institute of Technology are now automating some of the processes by which computer-based designs are turned into real world entities. They're developing techniques that fabricate building elements directly from digital designs, allowing custom concrete components to be manufactured rapidly and at low cost. "We're developing the research and the protocols to manufacture high-end customized architectural products economically, safely and with environmental responsibility," said Tristan Al-Haddad, an assistant professor in the College of Architecture who is a leader in this effort.

Nigeria Gas and Steel introduce structural sections

Eskom Limited Solar Water Heating Programme

Saldanha to get liquefied petroleum gas storage facility

Nigeria Gas and Steel Ltd has introduced into the Nigerian market their newest product the Hollow Structural Sections(HSS). It is used as structural elements in buildings , other structures and variety of manufactured products.

Eskom ltd has rolled out a large-scale solar water heating programme, to actively encourage and promote the widespread implementation of solar water heating. This programme will assist SA citizens when buying an SABS tested solar water heater to replace the conventional geyser.

Construction of largest liquefied petroleum gas (LPG) storage facility will start early in 2013 and the plant will be operational in late 2014 according to Ilitha Group.

HSS has greater strength-to-weight ratios than wide flange beams, also excellent compression characteristics and exceptional torsional resistance. HSS provides a uniformity of size, shape, strength and tolerances that makes its use totally predictable while it is also competitive in cost with other structural materials. With improved connecting and fasting methods it can often enjoy cost advantage. Nigeria Gas and Steel Ltd, formerly known as Mouke Pipe was established in 1976 and is based in Ikeja Lagos. The company is a long time expert in manufacturing of steel tubes and pipes of various sizes, shapes and thicknesses for furniture and construction industries.

The government has set a target for renewable energy to contribute 10 000 giga watt hours (GWh) of final energy consumption by 2013. Solar water heating could contribute up to 23% towards this target. Solar power is one of the most effective renewable energy sources available. By implementing it in water heating, we can target one of the most power-intensive household activities for maximum power saving effect.

The project, aimed at reducing LPG shortages that regularly hit Africa’s largest economy, will cost about 1,2 billion rand ($143 million), with imports coming from the Middle East, Gulf of Guinea and Angola. “We will be commissioning the facility at the end of December 2014,” said Barthlo Harmse, of Sunrise Energy, the company developing the site next to the Saldanha Bay port on the country’s west coast.

Focusing on the entire spectrum of electricity users – from private homes, guest houses, residential estates, factories and manufacturing plants to retail chains, car dealerships, financial institutions, commercial properties, office parks and farms – the programmes focus on identifying and promoting more efficient ways to use electricity, and switching over to energy efficient technologies.

Sunrise Energy is a joint venture between Ilitha Group and state-owned financier Industrial Development Corporation.

Zimbabwe

South Africa

An estimated 3% of the country’s 49 million people use LPG and the intention is to have an additional one million users over the next five years. Ilitha Group is spear heading this efforts to make sure the project is up and running by 2014.

Tokyo Sky Tree The tallest tower in the world The Tokyo Sky Tree has become the tallest tower in the world at a full height of 635 metres taking the position that was held by the Canton Tower. It is also the second tallest structure in the world after Burj Khalifa which reaches a soaring 829.84 metres.

found in any other city around the world. This new tower has been born based on the traditional sense of beauty and utilizing the advanced technology of Japan. The new tower will create a new landscape that goes beyond space and Urban Revitalization.

The foot of the new tower is shaped as a triangle. The number "3" is the smallest unit that can provide stability as exemplified by tripods. That rational shape minimizes any sense of over-bearing and the impact of shadows on the surroundings.

To create, connect and spread new life into this area where traditional Edo culture continues to live. The foot of the new tower is arched and shaped like three open gates. In addition, there will be two observatories - one 350m above ground and another 450m above ground. Restaurants, stores and other facilities are also planned for the 350m section to offer gourmet food and other pleasures while enjoying a commanding view of Kanto.

The shape was also chosen because it is symbolic of the triangular crisscrossing in the area of the Sumidagawa (Sumida River), Arakawa (Ara River) and the east-west axis of traffic. In addition, concerning the silhouette, the "sori" (concave curves) and "mukuri" (convex curves) seen in traditional Japanese architecture, etc. were the images in mind. The smooth curves that changes from the top towards the foot of the tower give the tower a dignified poise and an elegant air to it. Furthermore, as you move up from the foot to the top of the tower, the base form changes from triangular to circular. The varied appearances that the tower will have depending on the angle or place from which the tower is seen also makes this a landmark full of originality that is unlike anything 14

Plans are to set up a sky walkway covered in glass around the observatory lobby at an altitude of 450m, enabling the world's highest walk to be enjoyed. Moreover, a bustling complex with character distinctive of a shitamachi (the traditional name for the area of Tokyo extending from Taito, Chiyoda and Chuo Wards east of the Sumida River where many merchants, craftsmen, etc. reside) is being planned in the area surrounding the new tower to create an environment enjoyable for everyone irrespective of age or gender or nationality. July 2012


Watch Tower The new tower has been positioned as the core facility for the new digital broadcasting era and has the social duty to serve as the lifeline of the information infrastructure in times of disaster. Everything from structural form to construction techniques will involve the all-out mobilization of people with experience and expertise in state-of-the-art technology as well as traditional techniques.

Color Concept White, the color of the Tokyo Sky Tree as seen from the Sumida River, expresses traditional Japanese aesthetics. White recalls Japanese purity and sanctity as seen in snow-capped Mt. Fuji, as well as in the firemen's matoi and festival nobori banners, both of which are spiritual symbols of the old town of Edo. It is a color representing the traditional sense of beauty held by the Japanese people.

In addition, the new tower is aim to be a long-life structure that accounts for renovations, updating and other lifecycles and, at the same time, will contribute to the development of a center that satisfies the disaster prevention plans promoted by the area through being equipped with disaster prevention features. The five-story pagoda, representative of architectural techniques specific to Japan, is structured in a way that each floor is independent with a central pillar at the core. This structure and resulting interaction between the pagoda floors is said to help minimize the size of tremors in the event of an earthquake or during strong winds. The structural system of the new tower will recreate this five-story pagoda damping system using the latest technology.

The word shiro (white) in Japanese originated from shiru (know) or shirushi (sign), a color used to differentiate one from the rest and also to recall a symbolic value. The white Tokyo Sky Tree will serve as a symbol of the area and embodiment of the pride of the surrounding residents.

Tower Structure Learning from the technique of indigo dyeing, the white color for the tower will have a tint of blue in it to give a subtle luster, like the faint bluish white seen in white porcelain. Gray EV shafts give depth to the white tower structure, making the total tower design stand out in bold relief. The lath and metallic panels of the observation deck give an integral look to the tower structure, blending with the Tokyo sky. The brilliant white peak pointing to the blue sky symbolizes the spirit of innovation and the future.

White will serve as a screen to show the changes in the sky and the city, the landscape beyond time and space through all seasons. The night view will be even spectacular with the tower illuminated to stand out in the dark. It will capture the images of the vibrant community created by all walks of life who visit the tower. This is an original color based on aijiro, Japanese traditional color, and the lightest shade of indigo dye. Inspired by the technique of indigo dyeing, the Sky Tree White has a tint of blue in it. The faint bluish white gives a subtle luster to the tower as seen in white porcelains. The color created by artisans, a traditional Japanese handicraft, hints at the dawn of a new culture through the encounter of the Tokyo Sky Tree with the artisan culture, passed down for generations in the downtown area, where the tower stands. The tower clad in Sky Tree White will shine brilliantly under the blue sky of downtown Tokyo, transcending time and space.

Lake Champlain Bridge The new Network Tied Arch Bridge is a steel structure with an arch along the center span. The bridge's design makes it significantly safer than the previous structure and will ensure at least a 75-year service life. Key bridge components are designed to be easily replaceable to reduce maintenance costs. Travel lanes are 11 feet wide, with five-foot shoulders that will help accommodate larger trucks and farm vehicles, as well as provide ample room for cyclists. Sidewalks are featured on both sides of the bridge. The eight-story, 402-foot long, 1.8 million pound arch was constructed at Velez Marine in Port Henry, then floated down the lake and lifted into place. Building the arch on land was much faster, easier and cost-efficient than trying to safely build the arch high in the air above Lake Champlain.

18

The Structure The substructure is comprised of two concrete abutments and seven concrete piers that support the new bridge (the pier numbering starts on the NY side). The two concrete abutments, one at each end of the bridge, are founded on a series of 28 smaller micro-piles. Piers 1 through 6 are founded on a total of 32 6-foot diameter drilled shafts in the lake. Near the NY shore, the casings are about 40 feet long, while in the deeper main channel areas near the mid-span of the bridge, the casings are over 100 feet long. Pier 7, the pier closest to VT, is founded on a spread footing on rock on the shore.

teeth on the bottom of the casings were used to drill, or seat, the casing a minimum of 6 inches into the rock. Once seated in rock, the casings were emptied and cleaned of all soils and debris, and a 10- to 15- foot-long rock socket was drilled into bedrock at the base of the casing.

The 6-foot diameter steel casings were driven through the lake bottom soils until they reached bedrock. Once they reached rock, carbide cutting-

The completed drilled shafts were topped with a reinforced concrete pile cap, located at water level. The pile cap forms the foundation upon which the reinforced concrete piers were built. The 7 piers are essentially similar except the height of the pier stems varies depending on location. Once the piers were completed the steel girders were erected atop the piers.

The casing was then fitted with heavy spiral steel reinforcement and filled with concrete. The steel casings were used to facilitate the drilling and installation of the reinforced concrete shafts, and although they will remain in place, they are considered an interim measure as they are not accounted for in the design calculations or required to support the bridge.

The contractor secured a lease and all the required permits to assemble the center arch span at the Valez Marine in Port Henry, NY. The arch was floated on barges to the bridge site and lifted into place on the ends of the NY and VT approach structures using a heavy lift method. The center span was lifted into place without a concrete deck. This was done to limit the weight of the lift to just the structural steel components of the structure. To expedite the deck construction on the arch, precast concrete panels were used for both the roadway surface and the sidewalks, which are located on the outside of the arch. These panels were staged on barges, lifted by crane to one end of the arch and moved into position using rollers. After the arch was loaded with the weight of the precast panels, the final VT and NY approach deck pours were progressed. The transverse space between each precast deck and sidewalk panel was filled with concrete in a series of small transverse closure pours. With all of the transverse closure pours completed and cured, the precast concrete deck panel system was post-tensioned.

The final work included the pouring of the longitudinal closure pours on the arch span, pouring the remaining sections of sidewalk on the approach spans, installing the remaining bridge rail and pedestrian fence, installation of the bridge joints, diamond grinding the arch deck panels to assure smoothness, sawcut-grooving the bridge deck to provide wet weather traction, installing the navigational, handrail and aesthetic lighting, and pavement striping. Construction Team The construction contractor on the project was Flatiron Construction Corp. of Firestone, Colorado. Flatiron brought a core team of approximately a dozen managers, but hired nearly 500 different laborers, many of them local residents from New York and Vermont. Local subcontractors and material suppliers were used as well. The project to build the new bridge was completed by both the New York State

Department of Transportation (NYSDOT) and the Vermont Agency of Transportation (VTrans) as co-lead agencies under an agreement between the states. Under this agreement, NYSDOT was responsible for progression of the project and costs were shared equally by both states. As a result of the unprecedented collaboration between the partners involved in building the new bridge and the leadership of the two governors, construction was completed in just two years rather than the initial eight year projection. Work to construct the new LCB began in June 2010, and continued through the 2010-11 winter season. The construction of the LCB encompasses three major work phases: the concrete substructure, the steel and concrete superstructure, and the approach roadways.

Guest Providing Mass Housing In Nigeria

George Williams - architect Akivisions Design Team, Lagos, Nigeria

Addressing The Major Challenges In the heated ongoing debates in the various news media and other fora such as conferences and workshops about the acute shortages of shelter for Nigerians, especially in our urban centres, three major challenges are clearly identifiable. These are availability of mortgages to potential and interested homeowners, availability of capital for investment in large-scale housing production, and the cost of construction – in descending order of importance. However, the interplay between the three is so substantial that without the viable operation of all three simultaneously then scarcity of urban homes will continue to dog us relentlessly. Let us proceed to discuss why. Mortgages Just now, the availability of mortgages is the most critical issue in the housing sector. The few mortgage banks that are offering genuine mortgages are doing so at such astronomical rates as to make mortgages utterly unattractive.

At that Bank, interest rate on mortgages is no more than ten percent whereas tenor can be as high as 15 years. Still, this is not good enough if the housing sector is to reach its full potential. There has been in operation the ingenious idea of the National Housing Fund (NHF), where workers contribute a small fraction of their income to a central pool of funds, from which mortgage loans are made to interested contributors who apply to use the loan to build or purchase homes. 20

Most interest rates that accompany the available mortgages are at 15 percent per annum interest rate or more, accompanied by tenors as short as only ten years. Consequently, even if members of the public were keen to take up these mortgages, their inability to afford them automatically disqualifies a huge segment of the potential patrons. Although these mortgages obviously enjoy limited patronage from the public, most of these mortgage banks post annual performance results that flaunt impressive profits without revealing if these profits derive from their mortgage business - or otherwise. In other words, they conspicuously fail to tell us how many mortgage loans they successfully make annually. The only institution that offers a product that closely resembles a comparatively reasonable mortgage for homeownership is First Mortgages, a subsidiary of Nigeria’s largest bank by share capital, First Bank of Nigeria. At that Bank, interest rate on mortgages is no more than ten percent whereas tenor can be as high as 15 years. Still, this is not good enough if the housing sector is to reach its full potential. There has been in operation the ingenious idea of the National Housing Fund (NHF), where workers contribute a small fraction of their income to a central pool of funds, from which mortgage loans are made to interested contributors who apply to use the loan to build or purchase homes.

Interest rates for such loans are only 6% per annum, whiles the tenor applicable to the loan can be as long as 25 years. But the process of treating and eventually approving applications has become so notoriously cumbersome and protracted as to actually discourage potential applicants. In fact, the NHF managers have not in any particular year been able to boast of a significant number of successful applicants. From another point of view however, there appears to be justification why the fund managers are exercising caution in the approval of such loans. There is clear evidence to show that, because of the very modest interest rate attached to these loans when compared to commercial loans, many applicants seek to fraudulently obtain these loans to eventually divert them to other uses. But the fact remains that to attract meaningful and substantial investment capital into the mass housing sector, a benchmark of the number of mortgage loans that the NHF will have to make every year must be set and rigorously observed. Capital Investment In Housing Production Foreign Direct Investment (FDI) The often widely peddled impression that capital invested in the housing construction sector holds a lot of promise of profitable returns for the investor has proved time and again in many capitalist countries to be true without a shadow of doubt. But because housing investment is long term, and the frequent policy inconsistencies that normal arise over the long term locally, the attendant risks resulting from such inconsistencies have continued to often deter potential investors in our peculiar local circumstances. Government officials nevertheless stress that reforms are continually afoot to remove these policy hiccups thereby paving the way for sincere investors to plough their resources (especially Foreign Direct Investment (FDI) which hopefully will come in larger dollops) to mitigate the housing crisis - amongst the other sectors that are equally competing for this badly needed investment. But this begs of the question; ‘Are the potential returns on popular housing investment in the current operating environment truly attractive enough to bring FDI into affordable mass housing production?’

Building with Precast Concrete The use of precast concrete in construction is now widely regarded as an economic, durable, structurally sound, fire resistant and aesthetically superior form of construction. By Emmanuel Onsomu Precast concrete products are construction products produced by casting concrete in a reusable mold or form, cured in a controlled environment, transported to the construction site and lifted into place. Dissimilarly, standard concrete is poured into site-specific forms and cured on site. Precast concrete products can be said to be of better quality because precast concrete is produced in a controlled environment; it is thus afforded the opportunity to properly cure while being closely monitored by plant employees. Other benefits of utilizing a precast concrete system stem from the fact that the production process for precast concrete is performed on ground level, aiding with safety throughout a project and financially, the forms used in a precast plant may be reused hundreds to thousands of times before they can be replaced, allowing for cost of formwork per unit to be lower than for sitecast production. The use of precast concrete in construction is now widely regarded as an economic, durable, structurally sound, fire resistant and aesthetically superior form of construction. Versatility in Design Sarah Bachmann of the National Precast Concrete Association Australia (NPCAA) tells of new techniques being used by precasters around Australia that are adding value to traditional grey wall panels. She recognises that over the last 10 years the increased availability and application of form liners to create patterns, and stains as a 22

no maintenance 25-year alternative to a painted finish, has provided designers with a vastly increased array of textures and patterns. Adding to this is an extensive list of options in the form of traditional architectural possibilities, such as purpose built moulds, etched, grit (sand) blasted, exposed aggregate, polished and honed finishes are also available, as is integral colouring using pigments. And all of these finishes can be applied in the factory. Essentially one can only be limited by their imagination. Still on the subject of design, NPCAA also puts into perspective that on any total precast structure there are a number of critical design features that have to be addressed at the outset, including ceiling heights, load bearing walls, accommodation of lift boxes and some of the unique façade elements, in particular balconies. Once it is determined that the quality, safety and other requirements around these meet the brief, the design team in conjunction with the precaster is in a position to fine tune. The rest of the design refinement is centred around those issues. The essential requirement for any total precast project is to allow adequate lead time to allow such refinement. Interior design flexibility is provided by long span precast concrete flooring systems that help building owners adapt to changing client needs in future years. Precast flooring systems can span up to 17 metres to minimise the need for interior columns required with in-situ systems. Precast also provides high loading capacity at little added cost. The Green Factor The manufacturing process for precast concrete

uses less energy than comparable components, with less noise and air pollution and debris on site. Otherwise put, concrete is nontoxic, environmentally safe and composed of natural materials. Precast concrete products help to convey water without contributing to poor water quality. In line with this global trend towards environmental preservation is Los Angeles based Artisan Precast, manufacturers of precast concrete fencing and barrier solutions. Artisan applies ecofriendly standards across all production phases, from manufacturing to installation. The result is a line of precast concrete products crafted to meet or exceed green building guidelines. In addition to manufacturing their molds using VOC- and mercury-free polymers, the company’s fence component system is customized for each project to ensure minimal waste at the job site—which in turn helps preserve the landfills and cuts down on dumping costs. Pallets are recycled. Artisan also uses waterbased agents in the manufacturing process. Further color integrated into the concrete mix means the products need no painting or staining, which again avoids VOC release into the environment. The color has a fade rate of less than 2% over 10 years, which means virtually zero painting maintenance.

Solar Powered Generators Solar powered generators are an excellent back-up resource when a power grid fails. These noiseless, highly portable units work by storing power in batteries and then supplying the stored power to connected appliances as needed or on demand. Unlike the traditional gas or diesel models, solar powered generators do not require maintenance or refuelling. And while the initial cost of a solar powered generator is higher than a fossil fuel driven type, it will last as much as four times longer. These truly green gadgets have the potential of being a major supplier of energy all over the world; replacing gas generators. The Workings of a Solar Powered Generator Solar energy counts as one of the most promising alternative green energy sources with the sun producing a massive amount of energy that no man made unit can match. Solar power involves the conversion of sunlight into electricity either directly using photovoltaics (PV) or indirectly using concentrated solar power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic devices use photovoltaic cells or solar cells to convert solar energy to direct current or DC electricity. Other ways of collecting solar energy include solar panels, parabolic troughs, solar dishes, and solar power towers with reflecting mirrors. Solar powered generators are mostly used to power small appliances such as lamps, radios, or fans but can also be used to heat homes and businesses. They feature three main components namely a solar panel, a deep cycle or continuous battery and an inverter. The solar panel captures the sun’s energy and converts it into electricity. A solar panel commonly consists of interconnected photovoltaic cells made of silicon housed inside of a module or panel. These are normally protected from the elements such as rain by a layer of glass. The solar panel is connected to a battery which stores the electricity it has captured for when sunlight is not available. By design, deep cycle batteries provide a steady stream of current over a period of time and can be drained and recharged 26

multiple times. The deep cycle battery used in a solar powered generator should generally be rated for 12 volts. The energy stored in a battery is DC whereas appliances use alternating current, AC, and so the function of the inverter. An inverter converts the electricity into a usable form by changing it from DC to AC. The amount of usable electricity generated will be limited by the size and efficiency of the solar panel and by the inverter. A More than Worthy Replacement for your Fuel Driven Generator Solar generators have the potential to completely replace gasoline generators. While a solar powered generator generates power all day, storing it in batteries and supplying the stored power to connected appliances as needed, a fuel driven generator must be operating in order to supply any power to connected appliances regardless of whether the power required is minimal or intermittent. In this way, gasoline generators commonly provide power to appliances that consume only a small percentage of the generator’s rated power output, consuming unnecessary fuel. With a solar powered generator, fuel transport and storage logistics are eliminated. These devices are noiseless, produce no fumes and require minimal maintenance unlike their rivals. Once installed, solar panels have a life span of up to 20 years. Even more, a solar panel will produce power even in cloudy or low light conditions, making for a reliable source of power even in remote regions where other power sources may be difficult to

support or prone to failure. Solar generators also have a quick set up time and are highly portable. Despite high initial costs of installation, a solar powered generator will pay for itself after a few years of use, granted the sun comes free of charge. The constant supply of fuel necessary for the smooth functioning of a gasoline generator makes the overall cost of operating this generator much more than the initial purchase price, factoring in the ever increasing cost of fuel. A solar powered generator can be customised for specific uses, whether home or business. Solar Stik™ Founded in 2004, Solar Stik™ Inc. is a leader in the portable renewable power industry. Solar Stik™ manufactures renewable energy power generators, battery storage systems, power management devices, and high efficiency appliances. The system provides reliable power wherever it is needed from construction sites to remote locations. Lightweight, rugged, and extremely portable, the Solar Stik™ was designed for one purpose: to generate useable power. The Solar Stik™ Lite can generate up to 1.0 kW-h of average power per day, while the Solar Stik™ 360 Nano is capable of producing up to 3.0 kW-h. Depending on the environmental locations of planned use, wind turbines can supplement an additional 200 W-h. A solar generator like the Solar Stik™ can generate enough power in a day to support the constant power draw of several appliances operating July 2012


over a 24-hour period. It can also be used in conjunction with existing power sources such as Grid Utility, Portable Power Generators, Fuel Cells and more in a “Micro-Grid” configuration. A Solar Stik™ System operates with any 12 or 24 volt battery bank, or can operate as a stand-alone power source when the Solar Stik™ Power Pak is employed. Additionally, the Solar Stik™ is completely silent and emits no harmful fumes, which enhances its appeal as a power generator. Compared to a gasoline generator, the Solar Stik™ has its operating cost at nil, requires virtually no maintenance, and has a much longer manufacturer’s warranty for power output; up to 25 years depending on the system. Solar Stik™ Systems are also extremely light, portable, and rugged. A Solar Stik™ System can be described as “the proper blend of Power Technologies and Application”. Unlike competing systems, the open architecture of the Solar Stik™ allows for rapid adaptability and expandability. Users can incorporate other technologies into their system from appliances to generators. Setup of the Solar Stik™ System is “plug & play” and can be done by one person in less than five minutes. It can be erected for short or long term operation without concern for weather or environmental impact, making it ideal for use every single day. It can be set up and left to operate all day or all week. A single Solar Stik™ 100 can power applications that use up to one Kilowatt-Hour of power per day. If additional power is required, the Solar Stik™ panel output can be increased to 160 watts, or the Solar Stik™ Breeze can be employed to provide supplemental wind power generation. Additional Solar Stik™ Systems can also be added to meet the demand, or a PRO-Verter™ can be added to the system to allow a traditional fuel-driven power generator to be used as a supplemental source. Solar z20 Israel based Zenith Solar’s 3rd generation 'solar z20' is a revolutionary renewable technology that uses a combined heat and power system which utilizes semi-parabolic optical mirror collectors

to convert solar energy for both electrical and hot water use. Specifically, z20 features two 11m2 collectors, mounted on a dual axis tracker that concentrates incoming solar power onto a receiver. The receiver consists of a multi junction PV coupled to heat exchanger that converts concentrated solar flux into electrical power and thermal power. DC electrical power from the PV cells is converted to AC power and fed to the grid. Thermal energy is pumped through a closed loop system to the various users and applications. This high concentration photovoltaic (HCPV) technology enabled product has a record breaking efficiency of 72%; the highest in the industry in addition to offering the lowest cost per watt and the best potential for energy system cost reduction. And where its ability to pay for itself is concerned, the z20 solar generator provides for the shortest possible return on investment. Other beneficial attributes of the z20 include the fact that it is the only concentrated PV system to triple performance with captured thermal energy, it’s suitability for modular installations, inherent capability for easy upgrade granted the use of multi junction PV solar technology, best space utilization of land area and highest possible prevention of CO2 emissions through clean energy generation. To date the z20 has successfully been installed in Kibbutz Yavne, Israel, providing up to 230 residents with both hot water and electricity. Earlier this year, the company entered into a conditional distribution agreement with Greenearth Solar Energy to introduce the product to the Australian market. Mobile Solar Power System™ For many, using the words “mobile” and “solar” in the same sentence is challenging. Solar goes on rooftops, right? But for those in construction, the military, entertainment, emergency relief and other fields of work, mobile solar makes a whole lot of sense.

Mandhir Construction Ltd When the African Real Estate & Housing Finance (AREHF) Academy announced earlier this year that Mandhir Construction had emerged the Best Construction Company for Real Estate in Africa during their Excellence Awards held in Nairobi, it came as no major surprise. The Kenyan company has gradually established a name for itself in the sector, having successfully completed numerous commercial and residential development projects in the country. Founded in January 1988 and registered as a General Contractor Category B by the Ministry of Works, Mandhir Construction Limited has since executed projects ranging from residential maisonettes and apartments to hotels, lodges and factories. The company has also undertaken many refurbishment projects.

Kenya

Personnel The company is headed by an experienced team of technical personnel backed by administrative and support staff who all work in unison to ensure that projects awarded to the company are accomplished within the timeframe stipulated without compromising workmanship. Mr D.M. Ajmera, the Founder, had over 40 years experience in the building and civil engineering sector while Mr Manish Ajmera, a mechanical engineer, has nearly two decades of experience in the same field. Other key personnel include Mr Issac Mutua, a civil engineer who is usually the site manager in charge of building and civil engineering, overseeing construction projects. Mr Mutua also boasts nearly 20 years in the construction industry. Mr Lalji Patel, a technician is another member of the highly experienced team. He has 27 years in the industry. Equipment In order to accomplish projects on time, most contractors prefer to have their own plant and equipment. Mandhir Construction Limited has various machinery, vehicles and tools ready for deployment whenever a project commences. Some of these include dozers, excavators, compressors, concrete mixers, generators, block-making machines and vibrators. Others are winches, welding and drilling equipment, formworks and scaffolding pipes. The company is also equipped with several lorries, pick-ups and a saloon car. In addition, operations in the offices are fully computerized to make work easier and more professional. Some Projects Undertaken As mentioned above, Mandhir Construction Limited has undertaken many projects. Here is a brief look at some of them: 36

Mara Simba Lodge (Phase 2) Mara Simba Lodge is an exclusive tourist getaway in the Maasai Mara. The project involved construction of 42 rooms, extension of the dining area and other works. The contract sum was US$ 1.3 million. The project was undertaken in 1997. Ker & Downey Safaris Headquarters This project was on Langata South Road, Nairobi. It included office block, workshop building and guide bays. The contract was worth US$ 182,000 and was completed in 2000. Exclusive Bungalows for Casabella (K) Ltd This project, consisting of eight executive bungalows featuring built-in hardwood cupboards, granite tiles and other superior finishes, was along General Mathenge Road in Nairobi. Other works here included drilling of a borehole, cabro paving, plumbing and electrical installations. The project value was US$624,000. One Riverside Drive for AMS Properties This prestigious residential development project is on Riverside Drive in Nairobi. It was completed in December 2011. It consisted of luxury three bedroom deluxe and four bedroom duplex apartments with a Miami-theme on a sloping piece of land. It is considered a mix of luxury, beauty, class and environmental sustainability all in one. (see Construction Review May 2012 issue). Refurbishment of Mara Safari Club This is in the Masai Mara game reserve. It involves the addition of 15 new tents, a public area, swimming pool, septic tanks, electrical and plumbing works. The contract sum is US$ 3million. Flats for Focus Developers This project comprising 43 apartments is located along Msanduku Lane in Lavington, Nairobi. The project consists of seven blocks. Each block has five flats except one that has eight. The project includes a swimming pool, changing rooms, gymnasium, sauna and steam bath. The contract is worth US$ 2.2 million. Future The future of Mandhir Construction Company is bright. The firm will continue to live up to the highest expectations in all aspects of its interaction with clients and other players in the construction industry. July 2012

Office Block Complete Many outstanding features have been adopted in its design to achieve this ultimate end. This building employs unique external cladding aesthetics and external lighting which, without a doubt, provides an up-market Gaborone address, as is stipulated in the client’s brief. The concept of a Central Business District (CBD) in many thriving cities dates back to the 17th Century in London at the Exchange (near St. Paul’s Cathedral). It was later mimicked in the United States’ New York two centuries later in the 1800’s. A resurgence of CBDs even recently has been manifested in times of success and economic boom. For instance, London’s CBD evolved at the time when Britain was at the height of its Empire. Since then other nations have developed modern forms of CBDs, with examples from China’s Shanghai World Financial Centre and others like Dubai’ CBD. Botswana is currently embarking on a development of its own version of the CBD at the heart of Gaborone. Though several buildings have already been built and occupied, Gaborone CBD will boast grade A office space when completed as well as entertainment and other businesses, and commercial activities. The CBD’s first building - The Square (Shopping Mall and Office Block) - was a breakthrough which spearheaded further developments as manifest by the emergence of more buildings. Among these is an undeniably magnificent building, the new Exponential Office block, which is the first office block to be seen as one approaches the District from the South. This project started in July 2010 with an Advanced Earthworks contract and was completed in June 2012. It consists of a modern office block with 12000 square meters of lettable area, space to park 285 cars on grade on an 8600 square meter site, in a fully landscaped and surfaced environment. Modern and unique materials were selected in the finishes, such as external metal cladding.

Modern Design & Architectural Brilliance The client’s brief was to create a development that would define the CBD skyline and act as a landmark which stands out from surrounding buildings. Many outstanding features have been adopted in its design to achieve this ultimate end. This building employs unique external cladding aesthetics and external lighting which, without a doubt, provides an up-market Gaborone address, as is stipulated in the client’s brief. Design Philosophy The design philosophy was to assemble a modular floor plan that could accommodate as many as four (4) tenants per floor or one single tenant on a floor, or alternatively any number of tenants in between i.e. maximum flexibility. Site Appraisal This site was easy to work with as it was relatively flat, but with sufficient fall to drain naturally and thereby minimising the earthworks which were required. Challenges The main challenge which was encountered was determining how best to maximise flexibility for a wide scope of tenancy solutions. This problem arose due to the fact that the intended occupants were unknown at the time of design. Despite this, the problem was quickly remedied by a combination of innovation and flexible thought with a competent workforce, which has seen the office block stand out as the most beautiful building (especially at night).

Bidvest Steiner Botswana can Add Value to Your Building Project Bidvest Steiner Botswana, (Steiner Hygiene, SES & Wetrok ) is a one stop solution from start to finish for all building projects. We also provide continual upkeep and maintenance to preserve that “new building” feel. With branches in Gaborone, Francistown and Kasane – we are able to service and support across the country. Our services and expertise stretch from pest control, cleaning systems, hygiene dispensers and services. More than 15 years experience qualifies us to help the builder and construction project designer to stay ahead of the game. We would like to share our experience with the nation, to not only advise, but also create awareness that help is just a call away! We provide Pre- and Post-Construction Termite Prevention: During construction, conditions are often created that are either conducive to termites or may allow them to enter the building undetected. This is where we step in! There are precautions - which we offer - that can be taken to help reduce the likelihood of termite invasion. One such effective step is called Pre-construction anti-termite treatment. It is a scientific process of preventing entry of termites into buildings by creating a chemical barrier in the foundations of the building. Similarly, after construction - but prior to any landscaping - while concreting or paving is being installed, the perimeter of the property must be treated for termites.

Botswana

Treatment can also be done on existing buildings. Ongoing treatment, of termites and other pests such as rodents are also a vital factor to keep in mind. Before a building is occupied, it is always advisable to consult an

expert to ensure that the building is not already pest inhabited. Our highly skilled experts can identify tell-tale signs of infestation, block off all critter access points and further install preventative methods to ensure that the building and surroundings remain pest-free. Designing and Planning of Washroom Facilities: Hygiene dispensers are usually the last piece of the puzzle when designing washrooms. However, our experience has taught us that this should, in fact, be a key factor in designing the layout, because essential hygiene items often require special consideration in the layout of the facilities. Our consultants can advise the designer, offer a variety of products, to not only suite the style of the washroom, but to also ensure a perfect fit and positioning of all hygiene items. In addition, to ensure that the facilities are always looking their best – Bidvest Steiner offers a rental option. This way the dispensers and equipment are maintained and kept functional. Dust Control: The importance of proper matting should not be underestimated when it comes to dust control and preservation of tiles and carpets in buildings. Cost Advise for Choosing a Contract Cleaner: Wetrok has a long standing reputation for being a world leader in the provision of expert advice and cost estimation for quoting on contract cleaning. We work closely with major cleaning companies in Botswana to advise them on the correct products and equipment to use in order to save time and money as well as to ensure maximum hygiene and surface preservation.
