Sub-Saharan Africa has made rapid progress towards the Millennium Development Goals (MDGs) The Millennium Development Goals Report 2011 was launched in Geneva by the Secretary-General on 7 July 2011. The report, which presents the yearly assessment of global progress towards the MDGs, shows that although significant strides have been made, reaching all the MDGs by 2015 remains challenging because progress has failed to reach the most vulnerable.

The report says that the number of people in sub-Saharan Africa with access to safe drinking water increased from 252 million to 492 million between 1990 and 2008, growing from 49 to 60 percent of the population. But there are wide disparities: in cities, the poorest 20 percent of households are 12 times less likely to enjoy piped drinking water at home than the richest 20 per cent. Sixty-two per cent of the urban population lives in slums, the highest rate of any region.

Although aid to developing countries reached a record high in 2010, the report notes, only $11 billion has been received of the $25 billion increase promised to sub-Saharan Africa at the 2005 Gleneagles G8 Summit, owing mainly to shortfalls from some European donors that give large shares of their aid to Africa.

Kenya US$ 40 Million Loan for Rift Valley Railways The Board of Directors of the African Development Bank (AfDB) has approved a US$ 40-million loan to finance the Rift Valley Railways (RVR). The five-year US$ 246 million capital investment program involves two concessions over a rail network running from Mombasa in Kenya to Kampala in Uganda. The refurbishment and operation of the RVR is expected to simultaneously improve the quality and lower the cost of rail freight services in East and Central Africa. For example, the volume of goods transported is expected to more than double to 3.3 million tons per annum by 2015, while marginal costs are expected to drop by up to 30%. In the next 15 years, the project is expected to generate significant revenue for the Kenyan and Ugandan governments and have positive environmental effects by reducing the volume of goods transported by more polluting trucking services.
Local Contractors Offered Lease Financing to Face Foreign Competition

Tanzania’s local contractors can now acquire construction machinery through lease financing, thanks to an arrangement between GF Trucks & Equipment Ltd and Stanbic Bank Tanzania. "GF Trucks in collaboration with Stanbic Bank Tanzania have decided to introduce lease financing of construction equipment to Tanzanian contractors as part of the efforts to foster sustainable development," said GF Trucks Sales Manager, Mr. Eustachius Katiti. He also expressed hope that the arrangement would empower local contractors to compete with their foreign counterparts. Major construction projects in the country are being carried out by foreign construction firms, due to what he described as lack of modern equipment to implement the projects. Mr Katiti said apart from lack of modern equipment, local contractors also lack funds and experience to embark on huge projects. G F Trucks & Equipment Ltd was incorporated in February 2007. It currently holds franchise for products such as FAW commercial vehicles, Great wall light commercial vehicles, XCMG construction and Suchi Bus Company Limited.

Rwanda EIB Commits to Ruzizi III Hydropower Project The European Investment Bank, the long-term lending institution of the European Union and the world’s largest multinational lending body has confirmed that it will work closely with financial preparation of the Ruzizi hydroelectric project to be launched in Kigali. This landmark scheme has the potential to transform electricity supply to Rwanda, Burundi and the Democratic Republic of Congo, and would represent the first public-private sector energy engagement in the Great Lakes region. The overall project cost of the Ruzizi hydropower scheme is estimated to be US$ 535 million. The EU-Africa Infrastructure Trust Fund has provided US$ 4 million of grant funding for studies examining the economic soundness, environmental and social impact, water management and electricity links, and institutional strengthening of EGL.

World Bank Approves US$150 Million for Urban Development Project
The World Bank’s Board of Directors has approved a US$150 million loan that could see more than 2.8 million Ethiopians benefit from better urban governance, infrastructure, and public services. The new loan will scale up the support provided through the Ethiopia Urban Local Government Development Project (ULGDP) for performance improvement in the planning, delivery, and sustained provision of priority municipal services and infrastructure by urban local governments. Nineteen cities comprising about 42 percent of Ethiopia’s urban population are receiving performance grants for infrastructure, and another 18 cities will receive capacity building support to prepare them for future investment financing. During the initial three years of ULGDP, the participating cities performed better than had been anticipated when the project was designed. Citizen participation in investment planning has increased, and investment plans are closely aligned with the expressed priorities of citizens.
US$ 67 Million for Gitega-Nyangungu Road
Nineteen cities comprising about 42 percent of Ethiopia’s urban population are receiving performance grants for infrastructure, and another 18 cities will receive capacity building support to prepare them for future investment financing.
The Boards of Directors of the African Development Bank (AfDB) Group have approved a grant of US$67.23 million in funding for Phase II of the Gitega-Nyangungu-Ngozi road project in Burundi. The new finance will be used to fund the Gitega-Nyangungu segment of the road. Of the total, USD51.22 million is provided from the resources of the AfDB’s Fragile States Facility (FSF) and USD 16.01 million from the African Development Fund, the Bank Group’s concessional arm. Phase II is a follow-up of Phase I which was approved by the AfDB in September 2011. This phase will cover the development and asphalting of the Gitega-Nyangungu segment plus the rehabilitation of 22kms of rural roads, building pedestrian bridges, creating a heavy vehicles parking lot at Gitega, together with the development of socio-economic and commercial infrastructure. The work will proceed from August 2011 to March 2015. The project area extends from the centre to the north of the country and is home to an estimated 775,000 people. Gitega and Ngozi are the country’s second and third largest towns respectively.
Infrastructure Development Bank of Zimbabwe Invests US$ 100 Million in Projects
The new finance will be used to fund the Gitega-Nyangungu segment of the road.
The Infrastructure Development Bank of Zimbabwe has invested over US$100 million in housing, energy and transport sector projects being undertaken in conjunction with local authorities. This is in response to the Government's challenges in infrastructure development, with the advent of cash budgeting introduced at the onset of the multi-currency regime. The Government decided to actively involve partners such as local authorities to ensure that the IDBZ could adequately and speedily deliver on the selected projects. Among notable projects being financed by the IDBZ are power generation at Kariba South, Hwange and smaller thermal power stations in Harare, Bulawayo and Munyati. The Zimbabwe government also recently financed the upgrading of the Joshua Mqabuko Nkomo International Airport in Bulawayo with a US$5million budget allocation this year while last year US$4.1million was provided. 10

China World’s Longest Sea Bridge Opens After four years of construction China’s 42.5 kilometre Qingdao Jiaozhou Bay sea bridge has been opened. Stretching across the wide blue waters of Jiaozhou bay, the vast Y-shaped bridge connects the booming Northern port city of Qingdao with an airport built on a nearby island and the industrial suburb of Huangdao. It cuts the distance between Qingdao and Huangdao by 30 kilometres. The sea bridge, which is said to be the longest in the world, was constructed by state-owned Shandong High Speed Group at a cost of US$ 2.3 billion. 450,000 tons of steel and 81 million cubic feet of concrete were consumed in its construction. Qingdao is one of China’s fastest-growing cities. It is among the top ten largest container ports in the world, and is the main port of the Chinese navy. China’s 42.5 kilometre Qingdao Jiaozhou Bay sea bridge cuts the distance between Qingdao and Huangdao by 30 kilometres.

The Hoover Dam Bypass The Hoover Dam Bypass, which includes the Mike Oâ&#x20AC;&#x2122;Callaghan-Pat Tillman Memorial Bridge, was completed and opened to traffic in November 2010. It is the first concrete-steel composite arch bridge built in the United States, and includes the longest concrete arch in the Western Hemisphere. Project Team Contractors: R. E. Monks ConstructionVastco Inc.Edward Kraemer & Sons, Inc. Obayashi Corporation PSM Construction USA Inc. Las Vegas Paving Frehner Construction Company, Inc.
History Prior to completion of this project, the existing route of U.S. 93 used the top of Hoover Dam to cross the Colorado River. U.S. Highway 93 is the major commercial corridor between the states of Arizona, Nevada, and Utah; it is also on the North American Free Trade Agreement (NAFTA) route between Mexico and Canada. U.S. 93 was identified as a high priority corridor in the National Highway System Designation Act of 1995. The traffic congestion caused by the inadequacy of the existing highway across the dam imposed a serious economic burden on the states of Arizona, Nevada, and Utah.
Construction Inspection & Support: PB Americas PBS&J Construction Services
The traffic volumes, combined with the sharp curves on U.S. 93 in the vicinity of Hoover Dam, created a potentially dangerous situation. A major catastrophe could occur, involving innocent bystanders, millions of dollars in property damage to the dam and its facilities, contamination of the waters of Lake Mead or the Colorado River, and interruption of the power and water supply for people in the Southwest.
Environmental Impact Study Consultant: CH2M Hill
By developing an alternate crossing of the river near Hoover Dam, through-vehicle and truck traffic are removed from the top of the dam.
Design Team: HDR Engineering Jacobs (formerly Sverdrup)T. Y. Lin International
The joint venture contractor building the Colorado River Bridge, Obayashi Corporation and PSM Construction USA, Inc. completed the steel box girders; poured the concrete deck, pedestrian sidewalk, and roadway barriers, and worked on the pedestrian railing. Many detailed and important tasks were accomplished before the Bridge was fully complete.
This new route eliminates the problems with the former highway--sharp turns, narrow roadways, inadequate shoulders, poor sight distance, and low travel speeds. Design Work Design work for the Hoover Dam Bypass Project began in August 2001. The earlier studies and environmental evaluations had identified the Sugarloaf Mountain Roadway Alignment as the preferred alternative. The new roadway alignment begins near the Hacienda Hotel and Casino on the Nevada side and follows a route just south of existing U.S. 93 to the Reclamation warehouse area. This new alignment crosses over the existing roadway in a northeast direction, curves back around to the southeast and crosses back over to the south side of the existing roadway. The new alignment then proceeds in a southeast direction and cross the Colorado River approximately 1,500 feet downstream of the Hoover Dam. The new highway then proceeds past Sugarloaf Mountain and ties into existing U.S. 93 at about milepost 1.7 in Arizona. Construction of the bypass includes canyon crossing bridges, grade separation structures, wildlife crossings and the Colorado River crossing. Several power line towers have also been relocated to make way for the new highway. Now that the Bypass is completed the existing highway will remain in service but will not carry US93 through traffic. Read more on this article at http://main.constructionreviewonline.com

Movable Wall Have a party in one room and put your children to sleep in the other - the walls are perfectly soundproof! Change the appearance of your rooms every day - your imagination is the limit. In factories throughout the world, temporary office space is often needed for special short-term projects that require management personnel to be on-site. In the past, costly construction had to be done to create office space to accommodate the influx of workers. This was an inefficient process that wasted time and money.
Movable wall partitions have become today’s most mobile and flexible wall system as their advantage is making it possible to divide one room into several different ones with incredible sound insulation. With movable walls you can divide a large room into many smaller ones and turn it back into a big room again whenever you need to. 18
Today, office wall partitions provide a quick and effective solution for the creation of temporary office space. These movable wall systems can easily be maneuvered to create a custom space to suit any need. For this reason, plants everywhere are turning to these systems to accommodate their needs for temporary office space during their important projects. Mobility The most obvious benefit of office wall partitions is their mobility. While these movable wall systems are highly durable and stable, they can still be moved easily to create the perfect temporary office space. Whether one open office space is needed or a temporary office with several rooms, movable room dividers can create the perfect space for every need. Cost Spending significant amounts of money on a temporary office space just doesn’t make sense. What’s the point of spending up to hundreds of thousands of dollars for an office that will only be used for a short period of time? Office wall
partitions have all of the same benefits of traditional construction at a fraction of the price. This saves companies a considerable sum of money. Time Additionally, construction of a temporary office can be time consuming. Again, it doesn’t seem logical to waste precious time building an office that’s going to be used for just a few short weeks. A movable wall system can be put in place in just minutes. A variety of wall "systems" have been developed over the years to accommodate the need for access and flexibility of facility managers, each with unique benefits designed to meet specific interior wall requirements. Movable, demountable, operable, retractable, portable and systems walls are all terms of similar, yet uniquely different solutions to meet this challenge. As a guide for building owners, facility managers and architects, the various types of systems can be grouped and defined as follows: Operable walls Operable walls, also known as retractable walls, are usually the most expensive type of systems because of the support mechanism required to suspend the panels. Operable walls are generally individual panels hung from an overhead support with rollers. The panels are simply rolled into an open or closed position, either by hand or via a power-operated mechanism in the overhead track. Panels may be hung individually, as pairs, or as a group. This type of wall system requires structural support, so it cannot be moved from its original installed position. Panel surfaces vary from steel with a baked enamel finish to fabric covered tackable August 2011
Partitions surfaces and Formicar type laminate surfaces. Because of the complexity of the system, and the need for overhead support, prices for a typical operable wall are in the $20 to $45+ per square foot range. Operable walls are commonly used in areas that need to be divided instantly, by the building occupants. Excellent for use in hotel meeting rooms, gymnasiums, restaurants and classrooms, it's not unusual for an operable wall to extend to ceiling heights of 30 to 35 feet and higher. Sound Transmission Classification ratings are typically in the 38 to 52+ range. Operable walls are usually not fire-rated, and do not have power carrying capabilities. Portable walls Portable walls are also in the upper price range of the various wall systems, with typical prices in the $100 to $150 per lineal foot range, installed. Portable walls are individual panel units complete with a self-contained head and base. Panels are held in place by pressure, can be carried to a new position and installed very quickly. Most types require ceiling strengthening because of the upward pressure of the ceiling channel. Portable walls are commonly used in areas which need to be divided often, but in different layouts. These systems are popular in restaurants, hotel meeting rooms and in schools to subdivide classrooms. STC performance is typically limited, but since the system is used more as a divider than a permanent wall, sound control is not a major concern. Typically not available fire-rated, and these types of systems do not have power carrying capabilities. August 2011
Movable walls Movable walls are unitized panel assemblies connected at the joints with small panel connectors (also called "post caps"), or narrow reveals that may be slotted to accept hang-on furniture. The base and ceiling runners and trims are installed separately, and run continuously; panels are moved as assembled units. Typically the panel units and connectors are provided in a factory baked enamel finish. Movable walls are used to displace conventional fixed walls in all types of layouts. The systems are completely engineered including several types of door units and glazed assemblies. Because of the modularity of the system, door and glazed units are typically interchangeable with solid panel units. Since the panels are moved as assembled units, these types of systems move very quickly and are ideal for locations that require weekend or over-a-vacation changes. Movable walls generally have respectable STC performance, in the 39-43 range. Because of their factory painted finish, they provide a great deal of abuse resistance. Accessibility into the wall cavity varies by manufacturer. Some provide excellent accessibility; others have virtually no access except at the cavity between adjoining units. Electrification is normally handled at the joint cavity, and may require special "slimline" electrical boxes depending on the thickness of the system. Unitized assemblies typically do not allow for split finishes -- panels have to be the same on both sides of the unit.

Faux Tin Ceilings Tin ceilings have been around since the late 19th century. Originally a decorative and fireproof option to a plaster ceiling, tin ceilings have regained new popularity in recent years. Since a true tin ceiling, made of sheets of tin hammered into a design can be expensive, faux tin ceilings have begun to emerge. Among the options on offer, and the easiest for a homeowner to install is the faux tin wallpaper.
A ceiling style and covering add architectural and aesthetic qualities to the room. Ceiling styles and coverings can be combined to create a unique environment and accent the era and style of the home. High ceilings add a distinctly open feel to the room. Lower ceilings create a closer, cozier environment.
Those who want their home to be historically accurate will insist that there is no substitute for real tin ceilings. This design choice will give you the artistic and historic look of a real tin ceiling. There are tin ceiling panels that can be placed right over the existing ceiling for a quick and easy installation. Real tin will have to be primed so that the ceiling does not tarnish and you will find that there is a bit more work involved for these ceilings than faux materials. Many people will use tint on the tin ceilings to give them an antique look which can be very attractive in a period home. Faux tin ceiling tile is a great way to add to the attractiveness of your ceiling. The tiles simulate antique tin and come in various colors, patterns and finishes that will reflect nicely on you as well as your home.
Installing a faux tin ceiling can provide you with a number of benefits. However, there are also some drawbacks that you will need to be aware of. Here are some of the pros and cons of installing a faux tin ceiling. Pros One of the biggest advantages of this type of ceiling is the look that it provides. The look of a tin ceiling is very attractive and much sought after in the building industry today. It carries with it a very high-end look, so many people are going to enjoy it. If you are trying to sell your house, people will be drawn to this feature of the property. Another advantage of using a faux tin ceiling is that it can save you money. This is going to be much cheaper than actually installing tin ceiling tiles on the ceiling. Cons Although many people like the look of tin ceiling tiles, when you go with a faux finish, it may not look that realistic. Some of the faux finishes out there do not look like the real thing and people will be able to tell. Another potential problem with this type of finish is that it will require maintenance. Real tin is very
durable and does not require much maintenance, but the faux tin ceiling may. Faux Tin Tiles now come in a wide variety of colors and finishes such as copper, brass, chrome, whites, mochas, burgundies, silvers and gold. Not only do they come in these great finishes, but they come in a variety of sizes like the 6 in. pattern, 12 in., 24 in., all the way up to about 6 ft. When it comes to cost, for the enhanced aesthetics to your ceiling, the savings compared to more expensive metal ceiling tile, and the ease of installation the faux tin ceiling tile depending upon the design and style you choose can be obtained for well under $10.00 dollars a 12” x 12” tile. Which might be very appealing, especially to the capable do-it-yourselfer. Faux tin ceiling tile comes in a variety of colors, styles and designs and when you figure in the cost and ease of use it certainly has advantages that you should consider. Better Than Tin Better Than Tin is a company whose tiles offer a high-quality finish rivaling the aesthetics and durability of historic tin tiles, but at much lower prices. The tiles are dent and kink-resistant, lightweight, and easy to install in suspended ceiling (pop-in) or direct-mount (glue-up) applications. They can be used in almost any residential application including living rooms, dining rooms, bedrooms, kitchens,
bathrooms, basements, dens, home theaters, converted garages and even covered patios. They are especially ideal for kitchens and bathrooms because they are not affected by moisture, are easily cleaned and do not harbor, dust, mold or odors. The tiles are available in twenty-two styles, and the come in three metallic finishes (Brushed Bronze, Brushed Copper, Brushed Pewter) and a paintable white. The tiles start at only $1.99 per square foot.

Z-15 Tower Beijing's Tallest New Building The Z-15 Tower is a skyscraper designed for CITIC Group in Beijing, China. The 500m-high mixed-use tower will surpass the 330m-tall China World Tower, the current tallest skyscraper in Beijing. It will have more than 120 storeys and about 300,000m² of floor area. The tower has been designed by TFP Farrells who were chosen through an international competition. The final design was unveiled in January 2011. Inspired by Chinese culture, the design forms an identity for the steady financial growth. The tower will be well connected to the adjacent shopping mall and existing metro station. Being close to the China WTC 3 and the CCTV Headquarters, it is expected to become an international iconic landmark in the country. CITIC purchased the Z-15 plot for RMB6.3bn ($956.6bn) through bidding process. It will spend about RMB10bn ($1.5bn) for the overall site development. Facilities The planned facilities of the Z-15 Tower include the headquarters of the CITIC Group; 60 floors of Grade-A office space; a 20 storey, 300 room, six star hotel with state-of- the-art facilities; 20 floors of serviced apartments; galleries and a roof garden. "The planned facilities of the Z-15 Tower include the headquarters of the CITIC Group." Design The Z-15 Tower will be built at the heart of the new Beijing Central Business District (CBD). It is part of the city's master plan to develop a green business district on a 30ha site in the east of Beijing. The CBD extension will include 2,000,000m² of office space, apartments, six-star hotels and retail facilities. Several regional high-rise offices are located on both sides of a central green axis that leads to the site. The Z-15 Tower, at the end of the axis, will create a unique urban morphology with a sequential rising skyline. A vertical pedestrian circulation system with three levels of circular walking will provide access to the city transit system, malls and offices, and external and internal public spaces via landscaped environment. The tower will have rounded square floorplates to maximise the floor area at the top levels. The top of the building will accommodate the hotel, restaurant and bar, with a threestorey-high shared atrium.
Structure The Z-15 Tower will be a sleek structure with a smooth contemporary vertical curve. The building will reduce in size from the bottom till the middle and gradually increase till it reaches the top. "The Z-15 Tower will be a sleek structure with a smooth contemporary vertical curve." The shape will create a hyperbolic architecture with a central slimming. It will enhance the structural stability of the building at the base. The central core of the tower will house the service spaces and vertical circulation systems. The rounded square floor plans allow reduction of wind loads on the building. A shear-wall core and a skew frame are provided for structural resistance against earthquakes and gravity, while creating an aesthetic appearance. Façade The transparent façade will have a fully glazed curtain wall. It will have a texture
of different rhombic layers, which will rise from the bottom of the tower to the top of the building in a particular pattern. Inspiration The design was inspired by the Zun, a wine vessel, which has a long tradition in Chinese ritual forms. The aspect of the design creating large spaces at the upper floors of the building was inspired by the Kong Ming Lanterns form. The façade's appearance was inspired by traditional Chinese utensils that are woven with bamboo. Sustainability The tower has been designed and oriented for optimum use of natural wind in summer and sunlight in winter. An energy system for district heating and cooling is also being planned. The building will consume about 20% to 40% less energy than a typical building of this kind. A green belt landscaping of trees and plants is planned for around the tower.

Construction and EngineeringCompanies at Risk with Poor Suppliers By Brian Peterson, industry analyst, Coface
By Brian Peterson, industry analyst, Coface
The credit risk of companies in construction and engineering could increase as a result of using unreliable suppliers. Reliable suppliers can be the catalyst for businesses to succeed through tough times. Resource suppliers are scarce, primarily due to the consolidation of companies. This is the result of the credit crisis. Resources, whatever they cover, from building materials to soft services, are becoming more expensive and limited in availability.
Always remember that a company is only as strong as its weakest link.
Related to the housing and construction industries, resource management such as having a reliable raw materials supplier is a key element in business credit worthiness, the company’s credit rating and its financial survival. It is fundamental for any project to source the correct product at the right price. Coface has observed throughout the credit crisis the risk and credit insurance implications of utilising poor suppliers and its knock-on effects.
The dependency of the sector on Government infrastructure projects has become a case of survival of the fittest as many companies are expecting to grab a slice from the R800-billion set aside, and it is a waiting game until these funds are rolled out. The turnaround period for tenders is currently estimated at 200 days.
This could mean that a construction company has a materials supplier delivering inferior products or services, such as delivering late or the wrong products. Poor quality or delivery delays can result in payments not being released by the principle. This can create a credit insurance implication for the construction company and lead to a cash flow problem. If the construction company is not paid, it in turn is unable to pay other suppliers who may proceed with legal action to recover outstanding moneys owing. This could tarnish the company’s credit insurance profile. It can create further problems. If the cash flow dries up and the company continues to incur overhead costs, it may not be able to pay its creditors at all.
Construction and Engineering – Companies at Risk with Poor Suppliers 24
As a result, the expenditure hole keeps getting bigger because no funding is available. The construction company’s reputation and trade information could be tarnished. In our business we find that certain construction companies are in this catch 22 situation. In essence, the selection of a sub-standard, unreliable product or service provider can turn a construction company from a good risk into a bad one. Coface’s advice for selecting correct resources is to develop a strong relationship with suppliers, understand their business, find out where they get their product from, does the quality compare favourably to the market benchmark and shop around. The cheapest may not be the best and most reliable.
Construction Industry Still in a Lull Currently, the construction industry is still in a lull with most companies posting a slump in their results. The fall in the civil construction confidence index to 21 in the first quarter of this year from 27 in the fourth quarter of last year is the lowest level in 11 years.
The first quarter of 2011 has shown a slightly positive development in activity compared to the previous quarter. Not all the marginal activity can be blamed on the companies involved in building materials contractors, the sector also depends on other inputs to ensure delivery of service. There has been a shortage of rebar (reinforcing steel) which is important in construction. This is further slowing recovery in the building and construction sector, according to the South African Reinforced Concrete Engineers Association (Sarcea). This is likely to cause further cost increases and time delays for both contractors and developers, making it a necessity to import larger quantities of the product to cope effectively with shortages and further resulting in smaller companies not being able to compete. Outlook for the sector: There have been strides made by certain companies with projects outside the South African boarders for example:Murray & Roberts has won a R4billion contract to build a hospital in Abu Dhabi, and Raubex, along with Sanyati, are currently in final negotiations for R720-million roads project in Uganda.

Mpanga Hydro Power Plant licensed African EMS Mpanga Ltd, a local and private company to start off the project. Environmental protection South Asia Energy Management Systems in a drive towards environmental protection first acquired a certificate of approval from the National Environmental Management Authority (NEMA) in March 2007 before construction kicked off. This was the first major step which was followed by the hiring of Dr Kalema from Botany and Forestry Department in Makerere University. He worked together with another consultant from Sri lanka in the general environmental restoration in and the around the project site, but with much emphasis on the rare Cycad Encephalartos whytelockii to ensure its continuity by minimizing threats to its survival. Remarkable Features of the plant The Mpanga Hydro Power plant contains four major features and they include: Uganda

Construction of the power station was undertaken by a Sri Lankan hydropower construction company called VS Hydro (Private) Limited, at an estimated cost of US$26 million. The 18MW are sold to the national grid and also distributed to local communities. This will contribute towards sufficient and reliable energy supply to over 20,000 households and business entities in the Western part of Uganda. The power will also boost industrialization in the region which includes cement, tea, cobalt and agro-processing industries. It will also light hospitals, schools and community trading centers among others. The generation plant, developed by the South Asia Energy Management System, is another success story of the Public Private Partnership. In 2008, the government of Uganda
Weir: This is the point where water is diverted from the river and made to flow through a constructed canal for a specified distance. In the case of Mpanga, the canal is approximately 1.6km Canal: This is a long channel constructed along the river through which the water flows into a collection tank called the Forebay. Fore bay tank: This is a huge concrete tank where water collects. Here, the water gains enough pressure and flows at a very high speed through huge pipes called penstocks, to turn the turbines. Power house: This is where generation is done. It is where the turbines, the generators and all the other relevant generation equipment are installed. From this point electricity is then transmitted. Mpanga project has 3 turbines each generating 6MW giving a total of 18MW. Impact of the power plant The power generated is sent to the national grid where it is rationed according to national demand, by UETCL. However, part of the power will be distributed in the various institutions within Kamwenge such as schools, health centers and trading centers. Because of availability of power, small and medium industries are expected to come up hence boosting trade in the district. Also various large categories of persons who will be August 2011
Mpanga Hydro Power Commissioned. or have been attracted in and around the area, will create market for several goods and services. There are now good access routes to Mpanga area and this has eased access and mobility of goods as well as services. The environment has fully been renewed with planting of more trees to replace those which were destroyed during the construction and more species of trees have been planted as well to create a greener cover. The place has now been beautified with variety of flowers and different kinds of grass.

His Excellency the President of Uganda, officially opened the Mpanga Hydropower Project, in the Kamwenge District in Apri 2011. The 18 MW Power plant, built at the best cost ratios and in the fastest time for a hydro plant in Uganda, is now fully operational following a successful technical commissioning from February. The facility has a peak capacity of 18MW with a design flow of 16m3/s and a hydraulic head of 135m, and will deliver an annual energy of 68 Million units. The Mpanga Project was developed by Africa EMS Mpanga Limited a subsidiary of South Asia Energy Management Systems Inc., a leading American Renewable Energy Development Company. Project debt was brought in by a European lending consortium comprising of FMO Bank, DEG, Finfund and the Emerging Africa Fund. South Asia Energy Management Systems Inc. was founded solely to develop renewable energy projects in Asia and Africa. In addition to the 18MW Mpanga project in Uganda, SAEMS owns 11 more hydropower projects in Sri Lanka. SAEMS has extensive corporate and international experience in all aspects of project management including engineering, financing, vendor procurement, project implementation, quality assurance and power generation asset management. The construction was undertaken by VSHydro (Pvt) Ltd; a Sri Lankan-based hydropower construction company. Having constructed
more than 14 mini-hydro projects in Sri Lanka, VSHydro has extensive experience in the successful construction and operation of small-scale hydropower projects. VShydro is also an equity holder in a large portfolio of Sri Lanka projects. Six Ugandan companies worked as subcontractors and have received on site training in different aspects of hydro power project implementation. The project extended roads to five villages where only footpaths were the only means to reach many households. Agricultural produce is now collected directly from the houses of some of the residents. A football ground has been prepared for one the schools. Over 50,000 tree seedlings have been distributed to the communities. Over 200 local residents worked as casual labourers for the project. Some have picked skills that they are already applying in other parts of Uganda. A cycad nursery was setup to enhance survival of young cycads before replanting. This nursery has the largest young cycad population under special care in the world. In parallel to the project, the Rural Electrification Agency (REA) has carried out a large scale rural electrification program covering many villages in the Kamwenge district using the interconnection line from Mpanga. Thousands of village homes in the Kamwenge District shall henceforth enjoy electricity generated by the project. 31
Materials used Most of the materials used were procured locally and others imported. The locally purchased include among others cement, iron bars, steel bars, iron sheets, aggregates and sand etc. Imported equipment such as the turbines, generators, wires and switches came from Sri lanka, Europe India and USA.
UHMG HO Building and Warehouse Ntinda, Uganda The building is elegant in its simplicity and carefully articulated details. The master plan ensures that any future development will result in the maximum utilization of the site creating a contemporary office complex Uganda
The new headquarters for Uganda Health Marketing Group (UHMG) are located in a suburb that is quickly being transformed from a residential to commercial area. The 1.5 acre swath of land is located along Martyrâ&#x20AC;&#x2122;s Crescent, Ntinda and is 10 minutes away from the city centre. The client commissioned Symbion Uganda Ltd to design a 3 storey executive office building and warehouse to support its expansion within the country. The project team proceeded to provide conceptual and detailed designs that included a master plan to cater for future expansion. As project managers / architects, Symbion guided the client through the procurement process and managed the contractors throughout from commencement to completion. The development was completed on 4th April 2011, after a nine month design and construction period.
contains a 530 m2. mezzanine level used for administrative offices. The simple steel frame and masonry in-fill walls allowed for ease of construction, while the simple finishes were appropriate for the primary use of the building as sorting and storage of products. Parking The two buildings of varying functions on site necessitated the provision of separate parking for the main office building (with 70no. bays) and for the ware house (with 20 no. bays). Both parking areas are accessed off the Martyrsâ&#x20AC;&#x2122; Crescent Road . In so doing, there is minimum interruption between trucks and other vehicles.

Its completion marks another successful accomplishment of a project team led by Symbion within the Ugandan built environment. The building is elegant in its simplicity and carefully articulated details. The master plan ensures that any future development will result in the maximum utilization of the site creating a contemporary office complex. PROJECT SCOPE The main components of this phase of the project on the one and a half acre site were: the main office building, the warehouse and the parking area. Main Office Building This block consists of three floors each covering an area of 600 m2. The client, UHMG, occupies part of the ground floor and the entire first floor, a total of 725 m2. The rest of the space on the ground and second floor, 790 m2., is available to let. Each floor contains the necessary amenities of easily-accessible circulation cores, spacious and well-finished ablution areas, and adequate electrical and mechanical fittings. The flat roof slab currently provides a lovely terrace viewing deck and allows for future development if so desired by the client. Warehouse The warehouse was the first structure to be completed on site. This double height space covered a gross ground floor area of 630 m2. It also 32

located within the building appendages freeing up the bulk of the floor for office utilization. FORM The office building has a simple cubic form from which portions are either subtracted to create entrance foyers or added to create serving spaces. In the main elevation, one side of the geometric form sits shy of the form creating layering effect. This effect is further heightened by the juxtaposing of alucobond with masonry finish. The angular nature of the building is accentuated by the brilliant white aluminium strips and slabs that jut out from the building edge. The cantilevered mild steel brackets along the parapet wall provides a sleek cap to the vertical scale of the building. MATERIALS Exterior The office block aesthetic is composed of bronze curtain walling juxtaposed with gray alucobond cladding and beige painted block- walls. These three elements interplay on various scales and quantities resulting in clear primary and secondary elevations. The steel fins on top further strengthen the primary faĂ§ade.
SERVICES AND FACILITIES The office building is fitted with air-conditioning in the office spaces. There is lift substructure in place for future development. Firefighting equipment has been provided and includes: smoke detectors, fire hose reels, extinguishers, fire blankets, dry risers and a fire hydrant. The inconsistent power supply is countered by the provision of a 150KVA standby generator. Security measures have been considered in the use of CCTV and controlling access along the site perimeter. The buildings are also made universally accessible by the provision of ramps and disabled toilets. CHALLENGES FACED One of the challenges faced was the resolution of the site boundaries. An erroneous survey carried out earlier revealed discrepencies once works had commenced on site. This was resolved through discussions and agreements with the neighbours. Another challenge faced was the number of changes made by the client during the post-contract stage of the project. These changes brought about budgetary and time strains on the project. However with prompt and clear communication, the project team was able to meet the client needs without major impact to the project contract and program. The delayed procurement of some of the project materials by the contractor presented the third challenge. With the emphasis on the approval of samples as early as possible, the project manager was able to mitigate further delays and ensure the completion of the project on time.

LAYOUT The building blocks are laid out on a north-south axis to aid solar control. The position of both the present and future office blocks creates an open parking forecourt and conceals the warehouse at the back of the site. The position of the warehouse adjacent to one of the blocks frames the secondary delivery court adequately sized to allow for a loading and off-loading bay. The landscaped infill-spaces provide a soft green buffer between the existing and future blocks. Within the office building, the core contains curved walls and circular spaces around the meeting areas. These are flanked by openplan office spaces with adequate natural light and ventilation. The serving spaces such as staircases, ablutions, cleanerâ&#x20AC;&#x2122;s rooms and tearooms are
Interiors The Beige color theme provides the basis of the earth-toned finishes throughout the interior. These finishes include the brown and cream polished porcelain floor and wall tiles; powder coated aluminium partitioning and cherry oak veneered doors and fittings. The sharp contrast of the blue carpet tiles and dropped ceilings in the main meeting areas announces these spaces as special. These finishes provide a calm conducive working environment appropriate for the function of the building.

For developers a bankable investment, in the mist of economic recession, seems to be mixed-use developments. With its varied use, such developments tend to constantly attract business investors, tenants or patrons. Tshwane’s (Pretoria) newest addition to these developments is—The Club Project Team Client Atterbury Property Architect The Design Partnership Quantity Surveyor Storm Sciocatti South Africa
Structural Engineer DG Consulting Engineers Electrical Engineer Rawlins Whales & Partners Mechanical Engineer Q-Mech Consulting Engineers Electrical Consultant DC Electrical Main Contractor WBHO Very few mixed-use developments are constructed in a single undertaking, as many developers rather test the market’s response through a phased development. This fact holds true for The Club. The first phase is an office development, also named The Club, is a 4,500m2 block with 4 office levels, one ground floor retail level and a triple volume basement parking component. Developed by Atterbury Property, the development’s site was previously neglected land within the residential node of Hazelwood, between Waterkloof and Brooklyn suburbs. In developing the first phase, Atterbury sought an iconic building that would set the tone for the remaining phases of overall mixed-use development. Phase one is scheduled to go live in July 2011. Set on a triangular site the building’s design, spearheaded by The Design Partnership, was immensely influenced by site restrictions and the 46
sustainable energy principles incorporated into the building. Nestled between the Pretoria Country Club and the new Garsfontein N1 highway off ramp, space was extremely limited. Space was so restricted that typical landscaping that usually bounds the perimeter of developments, could not be executed with The Club. Its placement called for more innovative measures. “On the retail area’s roof we decided to lift the landscaping up and create concrete roofs over the outside area and put the landscaping on the building roof,” says Franzua Lotter of The Design Partnership. In order to maximise energy usage a number of solutions were implemented, including use of LED lights for energy cost-effectiveness as well as shaded glazing and controlled louvers to minimise
excessive heat gain, while reducing reliance on energy consumptive air-conditioning systems. Recognising that HVAC systems are consumptive in terms of energy use and cost, a cost-effective method was installed by mechanical engineers, Q-Mech. The Thermal Energy Storage (TES) provides partial ice storage, by doing so the HP chiller offers energy-efficient heating during cold winters. Standing at the corner of Brooklyn and Albert streets, one can tell that this impressive building represents just the beginning of something very special and defining in the area. Additional office developments and a 12,000m2 shopping centre will complete The Club mixed-use development in 2012/2013.

Dikgatlhong Dam Construction Reaches Critical Stage The contract for the construction of Botswana’s biggest dam enters its 39th month on programme, for scheduled completion in February 2012. South Africa
The current dry season’s activities are focused on the critical closure of a diversion channel purposefully left in the earth embankment to allow the previous season’s river flows to pass through whilst the dam was extended across the Shashe River. The 200m wide ogee crested spillway is also in an advanced stage of construction and final closure of the diversion and spillway section by October this year will see impoundment of the next wet season’s rains.
1.4 billion, is being funded by the Botswana Government. Construction is by Sinohydro Corporation from China and the technical design and contract administration and site supervision aspects are being undertaken by a joint venture partnership between Bergstan Africa, a Botswana based company and Jeffares & Green from South Africa.
The earth embankment dam is located in North-eastern Botswana about 3km below the confluence of the Tati and Shashe Rivers. At full supply level storage volume will be close to 400 million cubic metres with a backwater reach of about 20 kilometres up river. This will be Botswana’s largest water supply dam.
South African suppliers have provided steel plate for the outlet conduit, reinforcing steel, as well as the main outlet cone/sleeve and butterfly ranging from 300mm to 2.6 metres diameter. The cement was supplied by PPC Cement in Botswana. Subcontractor Geomechanics also undertook some core drilling and lugeon testing in the early stages of the project before Sinohydro mobilized their own drilling teams.
Transfer Pumping Station and Pipeline Work is also due to commence shortly to construct a large raw water pumping station and a 73 km long 1200 mm diameter welded steel pipeline, which will transfer water from the dam to connect with the existing national water carrier pipeline. From there, the raw water will be conveyed southwards to the capital of Gaborone, as well as serving settlements, new coalfields, and a proposed power station en route, via a second, still to be constructed, North-South carrier pipeline. Project Team and South African Content The project implementation by the Botswana Department of Water Affairs, at a cost of Rand
Challenges Overcome The 4.5km long by 41m high earthfill embankment required nearly 4 million cubic metres of materials for its construction, including crushed rock aggregates, gravel fill, sand and gravel filters and clay core. These have all been sourced on site following extensive geotechnical investigations and reconnaissance. The concrete for the construction of the spillway and intake tower is also manufactured on the site using the quarry sources identified above. The foundation geology was highly variable and required a multi-stage grout curtain totaling 58 kilometres in length and requiring the pressure grouting of 6 700 tonnes of cement to seal it against leakage.

The construction of a project of this magnitude in a remote part of Botswana presented a number of challenges to the construction and supervisory teams, including the language barrier and sometimes differing perceptions of construction practices, but these have been professionally dealt with and overcome. In addition, the works also suffered extensive damage caused by an unseasonal flood during the 2009 dry season. Another challenge was the poor and variable foundation geology and a paucity of good quality clay core materials. However, ongoing perseverance and dedication by all appears to be drawing the curtain on a project that is headed towards a successive conclusion, on time and on budget.

Soweto has recently experienced tremendous growth through new infrastructure designed to improve the quality of residents’ lives. From new public spaces, malls, theatres, road development and a public transportation system, soweto is being transformed. The new heroes bridge is a significant part of that transformation that is bridging the gap between the historic and the modern.

The completion of the R46 million (US$6.7million) Orlando Heroes Bridge marks a pivotal step in the development of the Orlando Ekhaya precinct. Just 25km from Sandton City and 22km from OR Tambo Airport, the overall R1billion (US$145million) project aims to develop a worldclass waterfront park, 3,000m2 of new retail shop space, 14,000m2 of office space, 60ha of open space and conservation development, as well as 14,000m2 of stylish residential components. In addition, famous landmarks such as the Orlando power station and cooling towers and the University of Johannesburg’s Soweto campus will undergo redevelopment in an attempt to refurbish the general look and feel of the area. The development will in essence provide a wide variety of entertainment and leisure activities and upon completion, the mixed-use development which is possibly one of the largest being considered in South Africa, will transform the Orlando precinct into one of the country’s most vibrant and sought after destinations for investment, business and tourism. The 130m long iconic structure spans the outflow of the Orlando Dam and also offers scenic views of both the Orlando Dam and the Orlando eKhaya precinct. In addition, it now links the suburbs of Orlando and Klipspruit, which were historically separated by the Orlando power station compound and in doing so will not only stitch the two communities
together, but it will also cater to the region’s fast growing transport network. The bridge, roadway, and nearby cross street are named in honour of local community heroes, Kingsley Sithole and Basil Zuma and also pays tribute to the ordinary everyday heroes of Soweto. One of the standout features reflected on the bridge is the innovative artwork and design by architect/artist Mphethi Morojele who, inspired by the themes of power and nature in the district, highlighted the power of ordinary people and natural forms. His work is world-class contemporary sculptural form integrated into the lighting of the bridge and road. From an economic standpoint, the completed project is set to attract new private sector investment and development into Orlando and Klipspruit by making the areas more accessible. Furthermore, the project has already created over 100 new jobs for members of the local community and in addition over R6 Million (US$870,000) of the contract value has been spent on local subcontractors and suppliers. The Orlando eKhaya development is a key growth node that cannot be underestimated. For many years Soweto has been the face of the South African struggle, however, it is initiatives such as the Orlando eKhaya Precinct , a previously neglected zone that once housed the Orlando Power Station (which only catered for the City of Johannesburg and not Soweto), that are gradually transforming the face of Soweto into a buzzing, modern and trendsetting metropolis.
Redirecting Commuters Easily in Kwa-Zulu Natal Getting around swiftly and efficiently in Kwa-Zulu Natal (KZN) is speeding up the development of two major interchange upgrade projects along some of the province’s busiest motorways. CHOTA MOTALA The need to reduce commuters’ journey time to and from the north-eastern areas of the city and minimise queue lengths on the N3 during peak hours, necessitated the Chota Motala Interchange. Jointly funded by SANRAL (South African National Roads Agency Limited) and the Msunduzi Municipality, this interchange project will include road widening, separating barrier, surface repair and upgrades as well as new interchange ramps. The project commenced in March 2010 and is scheduled for completion in November 2012. Upon completion of the project, the N3 leading to and from the interchange area will be widened, from its current two-lanes, to a four-lane dual carriageway. With increased lanes, comes increased traffic and speeds, so the need to further ensure road safety naturally followed. The construction of permanent New Jersey concrete median barriers, separating the north and south bound carriageways, are being built. A new interchange ramp is being constructed to ferry traffic on Chota Motala Road, from the eastern areas, onto the northbound carriageway of the N3. This ramp will direct traffic via a curved incrementally launched bridge, over the new widened Chota Motala bridge (that runs over the N3), to tie in with the N3 northbound carriageway. This specialised approach will create the first multiple-level road interchange or ‘flyover’ the city has witnessed. In addition to widening of Chota Motala bridge, the Dorpspruit River bridge will also be widened. Chota Motala Road will also be widened from single lanes running in each direction,
into a triple-lane dual carriageway. All existing roads in this project including Chota Motala Rd and the N3 lanes will be repaired and resurfaced. Inanda Interchange The Inanda Interchange is in the early phases of its construction, as the project recently commenced in March this year with a scheduled completion only in September 2013. Located at the intersection of the N2 and M19 (Quarry Rd) in the Durban Metro Municipality, this interchange will have two main directional ramps; one carrying traffic from the N2 (Southbound) to the M19 (Eastbound), the other from the M19 (Eastbound) to the N2 (Northbound). In the successful execution of this much needed interchange will be various ramps, commuter bridges, directional loops and pedestrian bridges. Funded by SANRAL and eThekwini Metro Municipality, the project was identified during the design of a recently completed project in the area. Goba, the consulting engineers, were charged with all the design work. One of the special road designs is converting the current bi-level interchange into a four-level interchange This interchange will have substantial aesthetic, yet functional structures that will add to its appeal. To minimise disruptions to traffic on the very busy N2, the main bridges of the directional ramps will be constructed by a highly specialised bridgelaunching technique. As with most major interchange or road construction projects, the main benefit is substantial relief of congestion during peak hours. An added positive outcome with the Inanda Interchange, is that it will become one of Durban’s landmark road features, just as the E.B. Cloete Interchange has been for years.

The Blackburn Pedestrian Bridge in KZN, and the Ubuntu Education Centre in Port Elizabeth, were awarded respective top honours in the coveted Civil Engineering and Building categories of the 2011 Fulton Awards for excellence in the application of concrete. The Fulton Awards winners were announced at a gala function at the Champagne Sports Resort in the Drakensberg on June 4.
“This remarkable structure provides the local people of Blackburn, Durban with a new, safe route to work, as well as lifestyle opportunities in the nearby Umhlanga New Town Centre. “Blackburn Pedestrian Bridge is one of the longest cable-stayed pedestrian bridges in Africa, and we were impressed by the careful attention to design and detail which was necessary due to the uniquely-shaped pylon”.
The prestigious awards are made every two years by the Concrete Society of Southern Africa (CSSA) with the Cement & Concrete Institute (C&CI) as anchor sponsor. Thirty-one major projects competed in the 2011 Fulton Awards’ six categories: Civil Engineering, Building, Concrete in Architecture, Unique Design Aspects, ConstructionTechniques and Innovative Technologies.
“The high quality finish was achieved from the exposed ‘durability’ class concrete which results in the minimum of maintenance being required during its life-cycle. Concrete was also chosen as the construction material for the two kilometres of associated walkway between Blackburn Village and Umhlanga”.
The Ubuntu Education Centre in Port Elizabeth won both the Building and Concrete in Architecture categories, with the Hospital Bend Preselection overpass road bridges in Cape Town being declared winner of the Construction Techniques category. Mountain House Roofs, also in Cape Town, won the Unique Design Aspects category. 15 Alice Lane in Sandton won the Innovative Technologies award. Civil Engineering category winner, the Blackburn Pedestrian Bridge near Umhlanga, was submitted by SSI Engineers and Environmental Consultants. In their citation, the competition judges said:
“The towering pylon and fanning stays of the bridge now highlight the capabilities of civil engineering and construction in South Africa”, the citation states. Ubuntu Education Centre in Zwide Township, submitted by John Blair Architects in association with Nongonyama Okpanume HewittColeman Architects, brought two Fulton Awards to Port Elizabeth. In awarding the prestigious Building Category award to the project, the judges noted that the entry “ticked so many boxes in the judging criteria”. “Concrete was chosen by the client to satisfy his brief of a building of permanence which makes a statement in the surrounding context. Aspects of ‘green building’ techniques were used, and the building utilises the thermal mass of its thick concrete walls and roof to radiate heat back August 2011
The Centre was also successful in the Concrete in Architecture category. Here the judges were very impressed with the use of off-shutter concrete as main element of the building, which provided a continuity of finish and form that met the design intent. “Reinforced concrete has been used as the principle building material for walls, floors and roofs to the project. A smooth off-shutter finish to the concrete has been used aesthetically for all external faces, and this finish has been carried through with good effect to the main interior walls. This provides the structure with a strong feeling of ethnicity “The concrete structure provides a sense of permanence and durability. The exposed concrete finish provides the necessary visual continuity to the folded slabs - which form both the walls and roofs - and to the complex supportive forms which are the basis of the design,” the citation states. The winner of the Unique Design Aspects category, a residential property at the foot of Table Mountain was submitted by architects, Hulme & Associates. The judges felt that the roofs of the property showcased concrete in a “very special and unique way”. Their citation says: “The organic shapes chosen for the roofs aid the house to blend harmoniously into the mountain backdrop. These also allowed unique views of the mountain, when seen from the inside, to be ‘framed’ with raised sections of the roofs – a very well thoughtout concept. The choice of concrete for the roofs shows perfectly its versatility, structural capacity, durability and aesthethic qualities.”
materials to not only improve resistance to marine conditions, but also reduce effective carbon emissions,” the citation concludes. Finally, 15 Alice Lane Towers in Sandton won the Innovative Technologies award for Sotiralis Consulting Engineers. “Concrete technology played a large part in bringing its various benefits directly to bear on the correct elements in the project. “The externally visible architectural form or silhouette of the building is that of two towers whose north and south faces are defined by irregular curves, resulting in a canyon-like atrium space between the two towers. This atrium space is about six metres wide at its lowest point, and eleven metres wide at its widest. The dramatic vertical space that results is enlivened by a series of precast concrete link bridges that have a fan-shaped arrangement in plan and spiral upwards in this tight space,” the citation observes. 15 Alice Lane Towers also won a Commendation in the Unique Design Aspects category. Other commendations were awarded to Group 5 for a Bridge Jacking project on the N17 Nasweto Highway in Soweto (Civil Engineering category); Aurecon for an Incrementally Launched bridge on the N1/R21 (also Innovative Technologies). A pioneering project that received a Commendation for Innovative Technologies was Southern Pipeline Contractors’ (SPC) Absorptive/Reflective Noise Barriers for Gautrain. This project, aimed at suppressing excessive noise, is a first in Southern Africa having introduced this essential technology against noise pollution to the region. SPC installed 15000m2 of barriers along sections of Gautrain’s route, specifically in residential and corporate areas reducing the impact of the noise source on the environment. The barrier’s have a life-cycle of 100 years and do not require any maintenance and can be produced in various shapes and colours to blend with their surroundings.
The Hospital Bend preselection traffic scheme, involving new overpass bridges for traffic flowing into Cape Town from Rhodes Drive and Settlers’ Way, scooped top honours in the Fulton Awards’ Construction Techniques category.
“This innovative technology has been introduced to South Africa and we commend the contractors for their foresight and creative thinking in solving this acoustical challenge.
The judges were impressed with the use of the suspended formwork system which utilised purpose-made structural steel lattice overhead girders with steel support structures, the design of which required extensive integration of the various design and construction elements.
Wood-fibre concrete has provided a viable and durable solution to reducing the noise along several sections of the Gautrain rapid rail route, and with the ability to shape and colour the material in various ways, it offers future innovative possibilities.”
“The Anzio Road Overpass was particularly challenging as the sharply curved bridge deck had to accommodate a vertical as well as a horizontal transitional curve, leading into a circular curve with a variable superelevation. “Impressive also, was the attention given to the concrete mixes, incorporating supplementary cementitious

into the building. “The new Ubuntu Centre is conceived as a node of intensity in a pedestrian network and acts as an on-the-way place of congregation, healing and opportunity. Designed to sustain the physical wellness and uplift the spirit of the community, it aims to propagate hope throughout the township,” the citation adds.

Noise generated by highway traffic is becoming a contentious environmental problem worldwide. Urban and residential growth means heavier traffic loads. The major countries and cities of the world recognise that effective noise attenuation is of crucial importance and therefore Noise Barriers are a basic construction requirement. People who live or work next to a highway are not able to turn the volume down or just walk away from the noise. They need an effective system to deal with this continuous stressful irritation. Noise barriers can be custom designed and manufactured for the reduction of noise levels emitted by road, rail and air traffic. It can also effectively enhance the quality of people’s lives when applied at bus depots, factories, industrial plants, schools, old age homes and hospitals. Southern Pipeline Contractors, operating in South Africa since 1965, is proud to be the pioneers in introducing this modern acoustical technology against noise pollution in Southern Africa. Specially designed precast concrete panels meet the acoustic requirements. Aesthetically it further offers durability, robustness, low maintenance and long term cost effectiveness.
SPC General Manager, Paul Phipps, receives the Fulton Commendation in Innovative Technologies for their Absorptive/Reflective Noise Barriers from Nic van den Berg, President of the Concrete Society of Southern Africa.
SPC Acoustics offers expert design and manufacturing service to: Identify where route barriers are needed Barrier location relative to source and receiver Barrier dimensions In-house technical support Experience in and resources to manufacture specialised products A current track record of innovation and success After producing 15 000m2 of absorptive and reflective noise barriers along sections of the Gautrain Rapid Rail Project to a lifecycle standard of 100 years, the latest project by SPC Acoustics involves the design and erection of noise attenuation barriers at the Rea Vaya Bus Rapid Transit System (BRT) depot in Dobsonville, Soweto.
SPC management celebrating the Fulton Commendation received for Innovative Technologies, are Peter Lycklama (Plant Manager), Sam Malemela (Factory Manager), Paul Phipps (General Manager) and Steve Delport (Sales Manager).
Amazing, isn’t it... the difference 10dB can make? Noise barriers are exterior structures designed to protect sensitive areas from noise pollution in developed countries, and it is proved that effectively designed noise barriers reduce noise levels by 10-15dB. An exact definition of loudness is impossible as there is a great variance from person to person judging the loudness of sound. However, as numerous research tests have shown, people generally judge a sound level of 70dB as twice as loud as 60dB.
“We at SPC are proud to bring this innovative technology to the people of Africa. The reduction in especially road traffic noise intensity is known to significantly improve the quality of life by relaxing the environment, resulting in improved verbal communication, recreation and night rest” says Paul Phipps, SPC General Manager.

Water, safe and potable, is taken for granted by many people with easy access to this essential ingredient. However, a life without ready access to water makes simple activities, like cooking and bathing, major challenges. In order to alleviate Dukuza residents from their daily chore of finding water, the uThukela District Municipality has completed the Dukuza / Hoffental Water Supply project.
Delivering Life’s Essential Resource To Dukuza The restive communities of Dukuza and Hoffental, just 13km west of the Bergville in KwaZulu-Natal, were identified as regions in dire need of reliable potable water supply. The communities comprise approximately 1,516 households and a total of about 12,500 residents. The project, through underground pipes, will link the communities to the existing Moyeni-Zwelisha water treatment works 8km from Dukuza and Hoffental. This is not the first attempt to provide a reliable water source to the communities, which traditionally had to travel great distances to collect water from the local Tugela River and carry it back for personal use. During the 1990s the Dukuza Water Supply Scheme, comprising 37km of pipelines, 75kl reservoir and break pressure tanks, was developed. However, this reticulation project had fallen into disrepair following the failure of the bulk water supply into the system. Further exacerbating the state of these pipelines were their poor construction, pipes exposure to the elements as well as informal house connections by residents. The new Dukuza-Hoffental contract includes the construction of 75km of ductile iron and steel PVC and HDPE pipelines of various
sizes; valve and meter chambers; break-pressure tanks; reinforced concrete storage reservoirs; a pump station; a 100kiloliter elevated steel tank on a 15m high steel stand and the installation of 180 communal standpipes throughout the area. Incorporating a bit of the old with the new, the contract was also extended to replace the existing Dukuza Water Supply Scheme’s reticulation with new pipelines, valves and standpipes. Engineered and designed by Jeffares & Green, the Dukuza-Hoffental project assists in the municipality’s overall aims and objectives of the Moyeni / Zwelisha Regional Scheme, which includes optimising benefits to the community by developing the sustainable water resource available in the area, the Tugela River. These projects also minimise costs and increase sustainability through use of existing water supply infrastructure. Regarding socioeconomic impact, the project also facilitates institutional development and training efforts across the proposed projects in the area, builds capacity through encouraging project participation by community members and uplifts the community through job creation.
