April 2015 Volume 26 No. 4

Africa today needs to generate cheap power to drive its development agenda and it is increasingly turning to coal. Globally 40 percent of all electricity is generated from coal fired power plants but Africa accounts for only a small fraction of this. The interest in coal has been spurred by lower costs of production of electricity using coal and an abundance of coal reserves. But coal does have its drawbacks not least of which is carbon dioxide emissions and toxic gases such as sulphur dioxide.

This is in addition to the pollution of ground water and environmental degradation associated with coal mining.

As the world has become more attuned to global warming this has meant that the West has placed more stringent measures designed to discourage the development of coal powered plants in Africa and elsewhere despite their own significant reliance on coal to generate electricity in their countries.

Despite this several countries in Africa are in various stages of development of coal fired plants led by South Africa which is developing 2 massive plants to stave off a crisis in its energy sector.

In Egypt the government has given a green light for Industries to import coal for use in development of electricity and notably cement factories have shown an interest in order to reduce their cost of production and remain competitive. What is clear is that as Africa develops its own coal fired plants it will need to learn from the mistakes of others and ensure that technologies to reduce pollution and emissions are installed to safeguard the health and lives of people and avoid smog covered cities.

Greenest insulating concrete forms might be gray

GROHE’s new EurodiscJoy faucet line combines modern operating comfort with award-winning design

SA Liviero develops new edge protection

The green building movement, already a huge factor in the residential sector, is likely to transform commercial construction as well. One pundit claims it will transform building in the same way electric lights and air conditioning did last century. Insulating concrete forms (ICFs) are well-positioned to take advantage of this trend; they’re durable, energy-efficient, and widely available. Among the various types of ICFs on the market, perhaps the most environmentally or Earth Friendly are the so-called composite ICFs, blocks made from a mix of expanded polystyrene (EPS) and Portland cement. Dan Chouinard with Earth Friendly Building Materials LLC is the new leader in composite block sales in the US and number one EPS (Styrofoam) recycler in Arizona. "If you’re not familiar with our product, EF Block it is an innovative ICB (Insulated Concrete Block) or ICF (Insulated Concrete Form) wall system made of over 85% Recycled EPS, Portland cement and other proprietary ingredients.

It is manufactured per the IRC (International Residential Code) screen grid and HUD (US Department of Housing and Urban Development).” says Dan.

Form and function at their best – a dynamically curved, slanted silhouette, a filigree joystick with smooth action, a sleek edge running along the spout – that’s all it takes to reinterpret a well-known classic faucet. If you are looking for ground breaking design, don’t look any further than the EurodiscJoy faucet line from GROHE. Combining visual lightness with easy operation, the EurodiscJoy is clearly a cut above the rest.

to

Recycled Content Composite Insulating concrete forms use a huge amount of recycled EPS that is usually destined for the landfill.

“Consider how many thousands of gallons of fuel, energy and labor are saved annually by no longer running landfill equipment. Consider also that EPS is a non-biodegradable product, which means we’re saving space at landfills as well.”

Freislich explains that, while most contractors in South Africa’s construction industry use European brackets, Liviero’s edge protection system was specifically designed for the local market. He adds that European brackets, which are used in conjunction with hollow steel tubes, are not designed to be used with steel tubes, but with high-grade timber properly

BoostStar Hydro-Pneumatic System Efficient water flow management in conditions of varying water pressure and fluctuating demand has always been a challenge. It is an even greater challenge to manage flow while optimizing energy consumption.

A road under construction in Kenya

US$ 547m is being sought by the Kenya Roads Board (KRB) to help in financing road maintenance in the country by issuing asset-backed infrastructure bond this year. KRB has also been given a nod to proceed with issuing an asset-backed security at the Nairobi Securities Exchange. KRB confirmed that some more money will come from the road maintenance levy fund, which annually collects a rate of Sh9 per litre of diesel and petrol. “We will securitize the fuel levy so we will be paying back the infrastructure bond from collections. The funds will help address the backlog of road maintenance,” said Jacob Ruwa, executive director of the KRB. The asset-backed bond will come in handy as it will aid in the clearance of the road maintenance accumulated backlog estimated to cost about US$438m, which has resulted from regular under financing of the country’s road sector.

Worldwide interest in doing business with Africa has never been so great. Demand from both Southern African and International companies for an umbrella event targeting African industry led to the creation of INDUTEC in 2013. INDUTEC is a synergistic mix of 12 events targeting companies involved in technology, manufacturing, engineering and energy, the water, gas and petrochemical sectors, plastics, pumps, valves and pipes, waste management, recycling technologies and sustainable resource solutions.

By the end of June, 2014, 3.1 billion litres of diesel and petrol was used – with fuel levy collection hitting US$ 306m in the same period, which is less compared to what KRB need for road maintenance. The roads agency has complained that the charges of Sh9 a litre which has been applicable since 2006, is no longer sufficient given the rise in cost of raw materials, labour and transport which has affected cost of road maintenance.

60 countries and over 80 African utilities attend every year. Clean Power Africa conference and exhibition is the largest event in Africa where major stakeholders from the clean energy sector get together to network, do business and meet new partners and suppliers, including IPPs, developers, utilities, municipalities and solution providers. The event, which is co-located with the 15th annual African Utility Week, will facilitate knowledge exchange at the highest level and will explore clean energy options as a feasible solution to fulfil Africa’s generation capacity needs.

CORPORATE NEWS

SODIC to invest US$301.64 million in Egypt Egypt’s property group SODIC has announced on Monday this week that it will invest US$301.64 million in 2015. CEO of SODIC Ahmed Badrawi has said the company is set to build 684 new property units in 2015. The company had announced last year that construction of first phase of its development in Heliopolis would start this year. The Sixth of October Development and Investment Company (SODIC) is an Egyptian company and has subsidiaries working in real estate sales, finishing works, landscaping and property management. Other interest areas include estate finance, interior design and specialised building materials. One of the company’s Hill projects is the Eastown, located adjacent to the campus of America university Cairo and near Cairo International Airport and will become the vibrant hub of the new Cairo district. The real estate development will include construction of a retail mall, an office park and residential units suitable to business people who have an international element in their lifestyle. The infrastructure in the town has been well developed with intersections to aid free movement of cars, cyclers and pedestrians. SODIC’S other development works include apartments, hotels and offices, Weston Business Park, Weston residence, katttameya exclusive apartments, strip and the Weston entertainment hub. SODIC is the third largest listed property group in Egypt.

Orascom Construction to list in Egypt and Dubai stock exchange Orascom Construction, a leading global construction and engineering contractor will be listed in the Egypt stock and Dubai exchange in early March this year. This follows Orascom Construction Industries Netherlands (OCI N.V.’S) announcement that it has commenced the formal demerging of the engineering and construction from its fertilizer and chemical business. The demerger is also planned to take place on March 7 this year. The move will attract additional investment for both companies and create a better business structure and allow them to engage in joint partnerships. Egyptian law requires that Orascom construction offers new ordinary shares which amounts to 15% of the shares to public retail investor, and through a private placement to qualified institutional investors. OCI N.V.’s share capital will reduce by $ 1.4 billion where OCI N.V shareholders will receive one Orascom construction share for every two OCI N.V shares they own. Orascom construction was delisted from the Egyptian stock exchange in 2013 a move which decreased the liquidity in the stock exchange.

All the government agencies have approved the project, and according to Rawal, machines are being assembled outside the country. The cement factory will produce 1.2 million tones of cement per year. CEMTECH which is a subsidiary of the Sanghi Group of India is in harge of the Green field cement factory project has said power generation will help cut down costs while providing reliable. power

An M.O.U has been signed between the Anambra State Government in Nigeria and the Bukham Group to construct 20,000 units of shops among other projects at Anambra International Trade Centre in Oba near Onitsha. The group will, in addition, construct 2,000 warehouses and hotels, a primary school, a cinema house, police post, health centre and a fire station at a cost of US$ 493.71m within a period of five years. Bukham Group chairman confirmed that the first phase is near completion and is expected to be inaugurated by March this year. Construction of 1,700 shops will be done in this phase and they will be ready to let. According to the governor, the government will support the project by building access roads to the centre from OnitshaOwerri road and Oba.

R&D Contracting installs state-of-theart roof for ABI When the time came for Amalgamated Beverage Industries (ABI) to refurbish the roof of its bottling plant in Devland, it looked for a business that has earned a reputation in the industry for its expertise in dealing with unusual roof designs. Since the ABI plant had been built using a very specific ‘origami style’ roof, a contractor with both this specific proficiency and an extensive track record in the commercial and industrial maintenance sector was required. Based on previous experiences with the organisation, ABI turned to R&D Contracting. The new roofing system will vastly improve inplant lighting and ergonomics.

Using waterproofing membranes for stone installations

By Arthur Mintie, Director, Technical Services LATICRETE International, Inc. Arthur Mintie

M

ore and more stone installations are being applied in wet areas.

These areas include showers, tubs, spas, steam rooms, fountains and pools.

These are generally considered constant wet areas and by building code and design specification, a waterproofing membrane must be used to protect spaces below and adjacent to the stone installation. The Tile Council of North America’s Handbook for Ceramic Tile Installations provide many details that depict the use of waterproofing membrane in an array of installation methods, including walls, floors, decks, tubs, showers and pools for ceramic tile application. Many of the same principles and methods apply to stone installations.

In addition, to the constant wet area applications, a waterproofing membrane can also be used in intermittent wet area applications. For instance, the floor areas outside of a tub or shower are great candidates for waterproofing membranes. In many cases, water spills or splashes out onto these area. Left untreated, the water can migrate through the stone and grout and affect the substrate and the spaces below. Even minor water damage can prove to be very costly to repair.

Many of the membranes available today serve a dual purpose; providing both waterproofing and anti-fracture protection.

The anti-fracture function helps to reduce the potential for hairline shrinkage and spider web cracks from telegraphing through to the stone surface. An excellent use area for these dual functioning membranes is 12

electric radiant flooring warming systems and hydronic floor heating systems. The membrane not only protects the spaces below and around the stone installation and the heating system, but it also helps to reduce the effects of thermal cycling that these types of installations can experience. The cyclying of the heating system can create thermal stresses in the setting system. The thermal stresses can cause small hairline cracks to transmit up through the stone finish. The use of dual purpose waterproofing and antifracture membrane can help to protect the stone finish.

Other areas that can also be waterproofed include, tub decks and surrounds, shower walls and ceilings, countertops, kitchens, exterior facades, building and home entry areas and mud rooms to just mention a few.

It has been proven that the use of waterproofing membranes within stone installations significantly reduces the potential for mold and mildew in wet areas.

Some of today’s waterproofing membranes come equipped with anti-microbial protection and help to fight the effects of stain causing mold and mildew.

Waterproofing membranes also help to keep homes and buildings healthy. They help to prevent the occurrence of poor indoor air quality by protecting against the effects of water damage, including rot, deterioration of building materials, mold and mildew. A few select waterproofing membranes are certified by 3rd party independent agencies for compliance with strict volatile organic compound (VOC) guidelines. These

membranes really help keep the building and home environment healthy!

Generally, waterproofing membranes for the stone and tile industry fall into three categories: Liquid Latex Rubber Applied Type 1. Sheet Type 2. Reinforced Latex Fortified Portland 3. Cement Type Within these categories are many membranes; which are thin and load bearing, adding no appreciable thickness to the installation and are fully compatible with latex fortified portland cement based thin set and medium bed mortars.

In order to apply the waterproofing membrane, the appropriate substrates should be properly prepared in a similar manner as if a direct bond latex fortified portland cement thin set mortar were to be applied.

In conclusion, stone can be successfully installed in wet area applications both for interior and even in demanding exterior applications. The use of waterproofing membranes makes sense in many stone applications. The investment that is made in selecting and installing these systems requires that consideration be given to this important installation feature. The added cost to include a waterproofing membrane in the stone installation is minute when compared to the potential repair or replacement costs that may arise from water and moisture damage. The use of waterproofing membranes provides great peace of mind to both the installer and the building owner.

African governments have voiced their insistence on going through with their plans to develop coal resources. When President Obama invited African heads of states to discuss business partnership possibilities in Washington last year’s at the first ever USAfrica Leadership Summit, many leaders said that coal was not to be left out as a strategy for powering Africa.

Tanzanian Minister of Power Sospeter Muhongo said "We should not be in the discussion of whether we should use coal or not...we are going to use our natural resources...We will start intensifying the utilization of coal." Chinedu Nebo, Nigeria's Minister of Power on his part said “Africa should be allowed to develop its coal potential. This is very critical. Africa is hugely in darkness.”

While the World Bank is bowing to pressure from environmental lobbyists to end funding of coal fired power plants, the African Development Bank (AFDB) has defended its position to continue financing coal fired plants. The Head of the Bank recently echoed the sentiments of most African governments when he said. “It is hypocritical for western governments who have funded their industrialisation using

Medupi Power project when completed will produce 4,764MW of electricity

fossil fuels, providing their citizens with enough power, to say to African countries, ‘You cannot develop dams, you cannot develop coal, just rely on these very expensive renewables’,” Ongoing coal power projects South Africa is leading the way in leveraging its huge coal reserves to generate badly needed electricity. It is estimated that coal meets over 70% of the country’s energy needs and Medupi which is South Africa’s first power station to be built in 20 years will be the largest drycooled power station in the world. According to Eskom the local power utility company the six generating units will each produce 794 MW of electricity for a combined total of close to 4,764 MW when it is finally completed. The Kusile Power project which is also currently underway is also set to produce 4,800MW when complete. Like Medupi it will have 6 generating units. Cheap coal to fuel the power stations and the desperate need to meet demand for power in South Africa have necessitated the use of coal and the results are expected to have a positive impact on the country’s power supplies that have bee plagued by load shedding in the last decade.

Nigeria In West Africa, a number of coal power plants are planned. Starting with Nigeria which will be counting on coal to produce 40,000MW of power by 2020 to feed its chronic shortfall. The Nigerian Electricity Regulatory Commission (NERC) has allowed Trombay Power Generation Limited to construct a 500MW plant in Gombe State. The Chairman of NERC, Dr. Sam Amadi said while issuing a license to the company in January this year that thorough examination had been carried out to ensure the project met strict standards in regard to feasibility and bankability. The country is also planning to boost power 16

production from another 500MW from a coal power plant to be constructed in Enugu State. The agreement for the coal power plant was signed in January this year between One Nation Energy Platform Ltd – the company undertaking the project – and the Federal government. In Phase two this project will generate a total of 1000MW. The country is hoping to generate 30% of its electricity from coal by 2015.

In Ghana where power demand stands at 2000mw with a deficit of 800mw, the Sunon Asogli gas power plant which currently produces 138MW has indicated it plans to use coal to produce more power in its next phase. According to Togbe Afede feasibility studies on the project are underway to ensure the production of 700 megawatts from coal in the first phase to ensure consistent power supply.

Egypt approves coal use Like most other African countries the failure to invest in power production facilities in the past has meant that supply has not kept up with demand. In Egypt which had placed a high reliance on gas power plants, failure to invest in new gas fields to supply power stations has meant that its 22,000MW power supply is fast becoming inadequate to the extent that early last year the government approved the importation of coal for generation of power by cement producers. This despite opposition form environmentalists.

Following this Suez Cement, Egypt's largest listed cement maker by market value is now going ahead with plans to spend US$84 million this year to equip two factories to run on coal to mitigate the countries energy shortfalls.

Another cement company Misr Beni Suef Cement will begin generating power for its cement plant by investing US$27.9m. It is only a matter of time before the country gets its first coal fired power stations supplying the grid. Already two coal-fired power plant projects have April 2015

been announced, one by a consortium led by a private Abu Dhabi-based company and another which will be developed by a JV of Egypt’s Orascom Construction and Abu Dhabi's International Petroleum Investment Co Kenya is also set to enter into coal powered plants.

Construction of the Lamu coal power plant is set to begin this October according to an announcement in February

by Amu Power, a joint venture between Centum and Gulf Energy. Amu has said that the 981.5MW power project will need 870 acres of land where the plant will be set up and that they were waiting to be granted the land. Amu will have the mandate to operate and own the development for 25 years. The government is hoping to get power from the plant to support heavy industries and the plant will be relying on coal imported from South Africa until Kenya starts sourcing coal from Kitui’s Mui Basin.

Lack of adequate power in Africa is also pushing investors in other sectors to invest in coal power generation for their operations. Dangote cement, will be investing in construction of Mbinga coal mine and power plant in the southwest of Tanzania to supply power for its Mtwara Cement plant. Dangote Cement will be counting on the demand of construction materials among them cement, to produce 3MT annually from the Tanzania-based plant.

Although the cost of the coal plant ha not been disclosed, it will produce 75MW. Kenya’s National Cement company is also planning on constructing a 15MW coal-fired power plant that would cost them US$19m in order to power their operations on planned limestone mining and clinker manufacturing factories at the location. The company will be counting on the plant to cut down operation costs while expecting to use 63,360t of coal per year. "The cost of procuring electricity from Kenya Power is twice as much when compared with the cost of generating power using coal," said National Cement. Kenya is still struggling to provide cheap power, with many manufacturers decrying of high electricity costs.

The Global Commission on the Climate and Economy in its September report on global use of coal called for middle-income countries to start retiring existing coal power plants by 2025 and developed/high income nations to “accelerate the retirement of their existing plants” indicating that coal as a source for energy may not be the future. The stark reality however is that Africa needs power and the cheapest source available is coal. While clean coal technologies have been mooted, the extent of how clean this can be is debatable. While western governments intend to withhold funding savvy business investors with less qualms concerning the environment are keenly snapping up opportunities to invest in coal plants across the continent as governments open up the sector to private investors.

The Egyptian government has approved the importation of coal for generation of power by cement producers.

WATERPROOFING

Concrete waterproofing Choosing the right product

C

By Dorcas Kang'ereha oncrete is known to be strong, durable and perfect for both utilitarian and decorative purposes worldwide. However, concrete is also porous, permeable and prone to cracking, therefore there is needs for protection so that it does not get damaged by water.

Water while essential in concrete production, placement, and curing is at the same time corrosive to the material, because once it fulfills its role in the production and other processes, it becomes an enemy to concrete. Although rated by its function and the nature of its exposure, concrete can as well perform well in wet environments.

Joseph Solomon a representative for Anti-Hydro International Inc a company that specializes in concrete waterproofing products suggests that, there is need for general awareness of waterproofing products as Africa emerges as a key global player with its vast natural resources and minerals.

Modern technology and revamping of the construction industry in Africa will be key to enhancing this vision.

Agreeing with this point of view is Rick Harris, the Director of Masonry Waterproofing Systems Pty Ltd. based in Australia, who says that, as the material use 18

gains momentum through awareness and is recognised ultimately for its performance and environmental qualities, waterproofing products will be indeed the efflorescence systems of choice for many years to come. The company is engaged in supplying and distributing the Evo product range worldwide.

Choices The choice of concrete waterproofing is first based on whether the structure is constructed or not. Integral waterproofing defines use of chemicals and additives (admixtures) in the concrete mixing process while preventive membranes and other applicants are used as “housewraps” after construction. Integral waterproofing is much better that use of membranes.

Benefits Exposure of concrete to water slowly reduces the permanence/durability of concrete structures, thus raising the cost of maintenance of bridges, buildings and other facilities. Water’s toxic effects on concrete structures can be avoided through the use of waterproofing technology, which efficiently improves the durability and lifespan of April 2015

retarder, so it helps to control the heat of hydration and consequently reduces shrinkage cracking. It doesn’t drastically change the properties of fresh concrete, but it can improve workability somewhat,” he says. PRANs can also help keep surfaces and walls cleaner since they reduce efflorescence. More on PRANs and PRAHsbelow.

Types of Concrete Waterproofing Admixtures Waterproofing admixtures reduce permeability of concrete, thus are known as permeability-reducing admixtures.

Additionally, these are classified in two – those used in nonhydrostatic conditions (PRAN) and those used under hydrostatic conditions (PRAH). According to American Concrete Institute, PRAHs are better than the PRANs. The best choice for waterproofing under hydrostatic pressure would be (water attracting) hydrophilic crystalline admixtures since they offer greatest resistance to water infiltration and best seal pores, cracks and offer longterm benefits. The reaction between the active ingredients contained in these admixtures and the water and cements particles, produce calcium silicate crystals. These crystals bond with cement paste and effectively seal the pores

concrete structures, hence reducing long-term maintenance costs. From coatings to sealers to membranes, enormous amounts of effort and money are spent in designing and applying such protection, with varying degrees of effectiveness, all with one aim of improving waterproofing to concrete. Thus waterproofing technologies can be helpful in reducing the costs. Water proofing technologies such as PRAs(Permeability-Reducing Agents) can save projects a lot. For example when power generation from hydrodams sometimes may need to be stopped to carry membrane waterproofing and expoxy-coated reinforcement, this comes at great cost. A good example is the rehabilitation of Kariba hydrodam in Zimbabwe and Zambia, whose walls have been deteriorating as a result of corrosion and blockage according to studies done on the facility – the two governments were set to receive US$294m from World Bank, European Union (EU), the Government of Sweden and the African Development Bank for the repair and the project will have to be undertaken over six years to achieve minimal disruptions.

Waterproofing concrete comes with other additional benefits according to Greg Maugeri, head of New England Dry Concrete, which distributes Kryton’s line of PRAHs(Permeability-Reducing Admixture for Hydrostatic conditions) in the northeastern U.S. “Besides reducing permeability, the admixture acts as a mild

and microcracks, and therefore preventing infiltration of water through the structure.

Cracks will be sealed over the lifetime of the structure since these reaction continues.

Concrete admixtures produced from waterrepellent chemicals (hydrophobic) materials such as soaps, vegetable oils, petroleum must be avoided since they do not uniformly seal all pores on concrete – concrete has larger voids – although they resist water infiltration by forming a water-repellent layer.

Use of concrete admixtures depends what conditions the structure will be exposed to; permeability is not a big issue with interior columns, beams, and floor slabs in high-rise construction, but use of PRA is important when a structure is to be exposed to water under hydrostatic pressure, wicking, salt water, or moisture or salt itself. They can be trusted in keeping off leaking of water, water migration, carbonation, freezing/thaw damage and efflorescence.

Dams, bridges, pools, water tanks, tunnels and subways that will experience more extreme and continuous exposure are better handled by use of PRAHs since they are effective in resisting permeability of water under pressure. PRANs are avoided when water to be resisted is under pressure but mainly used to help structures or products repel rain and dampness as may be needful in pavers, blocks, brick, precast panels and architectural concrete. PRAs waterproofing admixtures can be added in ready-mix concrete at the mixing plant as recommended by an architect or engineer. They can also 20

be added to any concrete mix. Experts can also recommend use of other types of waterproofing products on a building or structure that is complete.

“The typical dosage rate for crystalline PRAHs is 2% by weight of total cementitious materials,” says John Ladas, a sales representative for Xypex Chemical Corp.’s waterproofing admixtures, “except in an extraordinary case, such as an exceptionally corrosive atmosphere. We can also modify the formula depending on the circumstances.

We make one formulation that doesn’t retard set at all. We might recommend that for large flatwork areas, cold weather, or a mix that contains a lot of slag.”

Use of Waterproofing Membranes Waterproofing membranes are available in sheet form or liquid form. Liquid membranes are sprayed, rolled or trowelled onto the concrete surface and cure to form a rubbery waterproof coating. Sheet membranes come in sheet form and are stuck to the concrete surface to provide a waterproof barrier preventing water intrusion into the structural elements of a building or its finished spaces.

The material consist of waterproof plastic, rubber, or coated-fabric materials that prevent the entrance of water into foundations, roofs, walls, basements, buildings, and structures when properly installed.

Cementitious Waterproofing As the water and name suggests, the material is a cement-based compound with additives April 2015

that is mixed with other bonding agents to create slurry that can be applied to concrete surfaces for waterproofing. Materials such as fly ash, slag and silica can be mixed with concrete as fine particles to fill gaps and render it less permeable.

Cementitious waterproofing membranes have been used successfully to shield a wide range of buildings and structural components that are exposed to either periodic or longterm wetting, low hydrostatic pressure or, in combination with appropriate engineering, even high hydrostatic pressure.

The major applications are the sealing and waterproofing of terraces, basement walls, water tanks, swimming pools, walls and floors in wet-rooms such as toilets and bathrooms. The slurry membranes are easy to use and non-toxic. The membranes can as well be applied to wet or damp mineral surfaces since their physical properties are less temperature-dependent than bitumen based materials.

cracks or inside.

It helps protect structures against effects of aggressive chemicals. It also improves the water proofness and durability of concrete by filling and plugging pores, capillaries, micro-cracks among other voids which are non-soluble and highly resistant crystalline formation.

Concrete Sealers In the area of concrete sealers, there are those which penetrate the concrete and those that form a film over the concrete. They include wax, Acrylic Resins, silicates, and linseed oil substances, among others and applied on structures after construction. However, penetrating sealers does not change the appearance of the concrete at all, where as film forming sealers create a coating on the surface of the concrete that is unreceptive to water and other substances.

They can be acrylic, polyurethane or

Crystalline Waterproofing Exposure of concrete to water causes it to become a hard solid mass. The resulting byproducts of the reaction reside at the capillary tracts of concrete. Crystalline waterproofing is applied in the form of coating or as a dryshake application on the structure and acts when the chemical reacts with moisture and the by-products of reaction between concrete and water. This results in an insoluble product – in addition, this reaction occurs wherever water goes, whether in structure

epoxy, they are available in clear form or coloured depending on the needs. Using concrete sealers prevents concrete from breathing freely, absorbing water which can lead to a variety of structural and aesthetic problems. To a great extent, stains are also reduced, which helps keeping the floors and other concrete installations looking cleaner.

Sealers are easy to apply but may need to be periodically reapplied in order to maintain the waterproofing of the concrete.

ot even the best staffed architectural studios can thrive if designs produced do not reflect the client’s desires. Many architectural firms understand that listening first to the client is the most basic requirement before offering advice and proceeding to submit proposals. At FHG Architecture (K) Limited, this is a well known philosophy and it is practised religiously.

FHG is a design consultancy based in Nairobi, Kenya.

Although it has been in business for a few years, the firm’s predecessor had operated in the country for nearly a decade before reorganization that saw the birth of FHG Architecture (K) Ltd. A vibrant practice with substantial experience cutting across several architectural disciplines, FHG Architecture is keen on delivering projects that are creative, functional and aesthetically appealing within budgetary and time constraints. To that end, the firm has accomplished projects ranging from office blocks, healthcare facilities and gated communities to institutions and residences. FHG Architecture is driven by the primary desire of creating elegant, well designed and cost-effective facilities.

Among its numerous projects is The Axis, a high-end office block in the Westlands suburb of Nairobi built at a cost of more that US$ 5 million. The building provides a modern working environment and its design reflects FHG’s desire to use the client’s brief to create an elegant structure with all the amenities and features one would expect of a modern building.

22

Says Architect Samuel Thumbi, one of the directors of FHG: “We are a practice that strives to service the needs of clients, exceed their expectations and ensure their budgets are met.” His fellow director and architect, Andrew Kimani, agrees: “We believe our work is to create an icon after an icon by being keen and thorough while guided by integrity,” Other notable projects FHG has worked on include the Aga Khan Hospital Heart and Cancer Centre. In this project, Andrew Kimani was the Project Architect with a team of over 10 local and international consultants on three continents. The Design Architect was FNDA Canada who brought in a wealth of experience in the medical field leading to an ultramodern treatment facility that cost in excess of KSh1.8 billion (US$ 19 million).

Besides Aga Khan, other projects include the Eagle Plains Housing Estate, off Mombasa Road, and gated communities in Lower Kabete, Athi River, Syokimau and Nakuru; residences in Nyari, Kikuyu, Muthaiga and Runda, apartments, institutional projects and many others.

Outside Kenya, FHG has undertaken projects across the region including in South Sudan, and Tanzania.

The firm is keen on earning its rightful place among the big players in the industry by taking on bigger and more complex projects in Kenya and elsewhere in the years ahead.

On Course Kenya Ports Authority Nears Delivery of Second Container Terminal

Second terminal is just part of the Authority’s ambitious modernization and expansion programme.

Kenya

K

enya has experienced rapid development over the past decade mainly due to sound economic policies that were set in place shortly after the beginning of the new millennium when a reformist political administration took the reins of power. Among the concepts that have been guiding the country in its race to take its citizens towards an industrialized nation is Vision 2030. Vision 2030 is a long-term development blue-print aimed at creating a globally competitive and prosperous nation with a high quality of life by the year 2030. The Vision envisages a newly industrialized, middle-income country providing a high quality of life to all its citizens by 2030 in a clean and secure environment.

In order to achieve this ambitious target, various state organizations have adopted strategies to align themselves with this vision and have given themselves certain deliverables that are key to attaining this goal.

Among the critical organizations driving this growth is the Kenya Ports Authority (KPA), the public body that manages the country’s seaports. KPA’s biggest mantle is the Port of Mombasa. This port is considered the gateway to East and Central Africa, and is one of the busiest ports along the East African coastline. The port provides direct connectivity to over 80 other ports worldwide and is linked to a vast hinterland comprising Uganda, Rwanda, Burundi, Eastern Democratic Republic of Congo, Northern Tanzania, Southern Sudan, Somalia and Ethiopia by road. A railway line also runs from the port to Uganda and Tanzania.

24

In recent years, KPA has embarked on a massive programme to modernize and expand port facilities.

Among others, the organization has already completed and launched Berth No. 19 (see Construction Review November 2013 issue). The berth was constructed on reclaimed sea space using material extracted deep from the sea with engineers literally having to push back the sea to create land for the 240 meter long berth. The new berth brought the total quay length of the container terminal to 840 meters, enabling three Panamax vessels of up to 250 meter length each to berth at any given moment.

Constructed at an estimated cost of U.S. $ 66.7 Million, Berth No.19 has an additional stacking yard of 15 acres providing a further capacity of 250,000 Twenty Foot Equivalent Units (TEUs) per annum.

Another major project at the Port of Mombasa is the construction of a second container terminal as part of the port’s continued efforts to expand capacity ahead of demand. The project, which was commissioned in 2012, is on course with phase one scheduled to be ready shortly.

Its main objective is to expand container handling capacity of the port of Mombasa in order to match future trends, stay competitive in cargo handling and facilitate economic development in the Eastern and Central Africa region.

Another Tower to Shape Westlands’ Landscape

Integrated YMR Partnership

Pan Africa Life Assurance Building

T

Kenya

he development will be an iconic and landmark building along Waiyaki Way that will epitomise the rich heritage of Pan Africa Life Assurance as a distinguished and respected global brand. The design is timeless remaining relevant through its life cycle and an attraction for generations on end. The building is a modern and contemporary design that portrays the new face of Kenya. It has been designed with an attractive ambience employing creative use of colours to produce pleasant surroundings. The materials specified for the building are of high quality. The finishes and fittings both internally and externally will age gracefully and withstand adverse weather effects, dust, use etc. The building will have state-of-the-art lifts. As one of the greatest assets of Pan Africa is its employees, the following key attributes were identified as key for a conducive environment and therefore taken into account during the design: • Adequate provision of parking space: the parking caters

for the tenants of the building and visitors.

• Natural cross ventilation • Adequate and optimised use of natural lighting • Universal ease of accessibility for the disabled, visitors

and tenants. Access for office users, visitors, vehicles and

the physically challenged is easily identified and user

friendly. For vehicles, the design avoids congestion entry

and exit points • The design is an intelligent building that incorporates technology • A building that is secure • A building that minimises noise pollution from the road • Beautifully landscaped terrace garden for relaxation The project commenced in 2013 when a feasibility study was done for the project. Concept Design on the project started in late 2013 and was finalized in February 2014. Detailed design was finalized in December 2014. With scheme design complete and necessary approvals (NCC & NEMA) obtained in May 2014, excavation was started in October 2014 and will be complete in March 2015.

Unique Features and Environmental Considerations There is synergy between classical modern forms and pure natural forms in the building’s overall design. An iconic light tower at the top of the structure that forms the crown of the building will be visible from far.

New modern weiler Slip former plant for prestressed foundation piles

T

he Ukrainian construction company Khmelnizkzalisobeton (“KHM”) – produces hollow core slabs with a Finnish extruder production line, and reinforced foundation piles made of wet-cast concrete in molds. Up to 4.000 foundation piles are needed for each project, and the existing production method could no longer meet the requirements for high capacity production while respecting design tolerances. At the end of 2012 KHM visited weiler GmbH in Gau-Algesheim – 60 km away from Frankfurt airport – looking for an advanced foundation pile production system.

KHM required a daily capacity of 1.000 linear meters of foundation pile with cross sections 30x30 and 35x35 cm and lengths up to 18m. The new system plant had to fit into an existing hall. During a second factory visit, weiler demonstrated on its own test track the

new MULTI-caster ® to KHM (using drymix concrete.) The visiting team of KHM experts was convinced, leading directly to a handshake deal!

Customized & tailor-made Solution weiler engineers designed and installed the new weiler MULTI-caster ® line into an existing hall with 24 x 100m of floor space.

On 6 steel casting beds, each 96m long, foundation piles and lintels are being slipformed continuously, using the new weiler MULTI-caster ® with 3 quick-exchange cartridges.

After only 8 hours curing time the products are cut to the required lengths with a high performing weiler concrete saw.After lifting of the cut elements, the production beds are cleaned with an LPG motor driven

weiler “weasel” – this machine also sprays demoulding oil and pulls pre-stressing wire.

Production targets surpassed

By April 2014 KHM took over the plant, ready for operation. Today, with only 8 operators, up to 1.700 linear meters of foundation piles are being produced in a single shift operation.

Shorter curing times, significant material savings, substantially higher performing final product, reduced steel content, minimized need of cement – approx. 200 kg cement less per m³ of concrete means approx. 2.500 € of savings per day!

Concrete hard benefits!

KHM’s production chief commented on the results very directly: “that’s simply great!”

The neutral tone of the “Powder Grey” shades and the clean simplified lines of the rectangular benches outside the building compliment the architecture and landscape.

The third floor’s perimeter is lined with fifty nine custom made rectangular planters in a “soot” shade. The stunning moment about the Annex is when one sees the beautiful external landscaping of the Alice Lane Towers, where sugar bowl pots and ulterior table benches have been beautifully settled amongst the outdoor areas.

The Alice Lane Annex was completed mid last year and currently has one tenant occupying the first three and half levels of the building, with the two serving as the new home for a separate tenant. The Annex was constructed

andton Skye, a residential complex located on the corner of Stan road and Grayston drive in Sandton isanother development designed by AMA

Architects featuring three towers of 17 floors. The 34,900 square meter landmark development, constructed at a cost of R1.5 billion (US$129m) is practically the benchmark in the investment property. It consists of a mix of one and two

First phase The first-phase tower of Sandton Skye was completed in October 2014 and, the construction of the second phase has commencedwith the third and final yet to be constructed in the near future.Sandton Skye is a pinnacle lifestyle development in Sandton, where a new sphere of luxury has been introduced to South Africa’s richest square mile.

This is a five star “urban resort” offering a world class experience, with its iconic assemblage of three wonderfully crafted towers situated on a dynamic public facilities podium. It is also a residential project with a difference in that it will function in a hotel-like fashion with luxury hotel-convenience facilities, trendy restaurant, offering a red carpet experience, cocktail bar, indoor pool.

Kids are allowed into this “urban resort” where there is a kids zone inside.

The development is a blue chip investment opportunity in the financial hub of Sandton with 80% of the apartments being priced at less than R2 million(US$172,000) at a fixed contract price, not linked to CPI or inflation, explained Lynn Petzer from Lynn Estate, who played an integral part in evolving the Sandton skyline over the past 21 years.

the inside out, and further redefined in each of the 17 stories through a sculptural exterior skin that is layered in colored glass, stone cladding, aluminum and plaster render. Across the corners of these apartments is a generous panoramic view from a premium vantage pointing one of the most privileged positions inSandton.

Interior The individual expression of the vibrant colors’ on the fabric and artworks that will be placed in thecrisp interiors, complement each other perfectly, where white is placed on white, gray on sliver, and charcoal on grey. In addition 3500 square meter of landscaped gardens including an outdoor rim flow pool with wooden decks and double day bed lounger makes the SandtonSkye lookdifferent from the other residential developments in terms of the luxury of green space.

Not much brickwork was used within the Sandton Skye building (phase 1) and instead a dry-wall system was used for most of the internal walling.This posed a challenge when they had to come up with a solution of how to accommodate the entire plumbing South Africa

system within these dry-walls but this was overcome by the use of prefabricated frames from Modern Plumbing Works which turned out to be the perfect solution for theSandton Skye project.

The completion of all the three towers is set to be in 2020 Sandton Skye Roof Drainage System Geberit are proud to be part of the prestigious Sandton Skye project, working close together with the project team on the drainage system, ensuring the best possible and most effective solution was installed.

The GeberitPluviasyphonic roof drainage system coupled with the Geberit HDPE piping was cleverly designed to do more than effectively drain the rain water from the roof, podium and terraces.

Insteadthe water is collected and reticulated to discharged into the attenuation tanks.

The drainage system was further optimised by using the innovative GeberitSovent fitting, designed for use in high-rise and multi storey buildings such as the Sandton Skye. GeberitSovent not only delivers an extremely cost effective, high performance drainage system, it allows for clear and simple piping layouts, saves space in the duct, uses less material which ensures a quicker installation time.

Due to its high capacity and excellent performance GeberitSovent is an ideal drainage solution for any high rise building. Drainage means more than just draining away water – at least as far as Geberit is concerned.

Geberit invests a good deal of know-how in the development of innovative products and solutions to ensure that drainage technology keeps up to date with the needs and requirements on the building site.
