Construction of large dams has come under intense criticism recently with proponents labeling them as uneconomical and a burden to governments when cheaper and far appropriate options exist.

The Tekeze Dam located in Ethiopia is the tallest in Africa at 188m and will generate 300 MW of hydrelectric power.

Do massive HEP projects really deliver on their promise?

The massive size and imposing nature of hydro electric power stations have for a long time been viewed as a mark of development in Africa with the belief being that they offer not only a sustainable source of energy but also control flooding of rivers and provide water all year for irrigation, who can argue with that?

I recall this from my own high school geography class and the field trips we made on at least one occasion to view with awe this feat of engineering. Recent research suggests that the extended time lines and cost overruns are just a few of the negative economic repercussions of these massive projects that in some cases have put their overall benefits into question. This is even before considering the social and environmental aspects that have been advanced in the past.

In this issue we examine this controversial topic that seeks to separate fact from fallacy. It also looks at what the alternatives are since the need to meet an ever increasing appetite for energy still needs to be addressed.

Jeffreys Bay Wind Farm

Electrical engineering and electronics company Siemens is joining partners in the inauguration of the Jeffreys Bay Wind Farm. The launch of the wind farm is a re-markable milestone for South Africa as it is one of the largest wind farms in the country. The site spans a 3700ha site and comprises 60 Wind Turbine Generators with a capacity of 2.3MW each supplied by Siemens. The wind farm, which has been developed by a consortium which is majority owned by Globeleq and its consortium partners that include Mainstream Renewable Power South Africa entered into a 20 year power purchasing agreement with Eskom, governed by the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP).

A new mass transit electrified railway upcoming in Batna

International companies are invited by Metro Company (EMA) to bid on a project for the construction of mass transit electrified railway. However, a number of specifications must be met for participation. One is the requirement that they must have a 10 year’s experience in implementation of at least one light rail or tram project. The line will entail a total of 25 stations and will run 15 kilometers from urban pole of Haley 3 to the Cité Bouzourane, passing through the University

Hadj Lakhdar. Batna is the main city in the province of Batna. The whole country has a total of a total of 3,973 km railway, some being partly electrified. Companies wishing to be considered must separate financial and technical offers in their submissions and submit in two different closed envelopes. According to EMA, the submissions are expected 3 months after the first publication of the tender on the national press. This, according to calculations, is expected to be about 20th September 2014.

Second Phase of the Lesotho Highlands Water Project underway

New Bugesera International Airport Project

“Siemens delivered and installed SWT-2.3-101 turbines with 80 meter hub height. Through various milestones, today we have connected all 60 to Eskom’s grid. This bodes very well for diversifying our energy mix. Renewable energy is arguably one of the key pillars of sustainable growth," says Pedersen, Head of Wind Power Division at Siemens. The model of the turbines installed in the farm has firmly established itself as the tried and tested workhorse for reliability and set a new standard for productivity.

“It has been a tremendous journey for our partners and all stakeholders involved. We have formed a solid ground for wind energy in the country from which valuable expertise and experience can benefit future projects in the continent." Pedersen concludes.

The second phase of the Lesotho Highlands Water Project which is a bi-national project between the governments of Lesotho and South Africa was launched recently and is expected to cost US$1.3bn. The treaty signed between the two governments will set relevant structures that will help implement the whole project. The first phase of the project was split into 1A and 1B. The main physical features of Phase 1A are the Katse dam, the transfer tunnel from Katse to Muela Hydropower station, The Muela Hydropower station and appurtenances and the delivery tunnel to the border with South Africa. Phase 1B involved the construction of the Mohale dams, the diversion tunnel to the Katse dam.

The second phase of Lesotho Highlands Water Project will comprise the construction of 155metre-high Polihali Dam and tunnels. According to the president of South Africa Jacob Zuma, the whole project is a good opportunity for both countries since it will create a good relationship between the states and also create employment. The president also noted that through the project, South Africa will be able to get water given that it has scarce water resources. On the other side, Lesotho will be able to earn sufficient revenue to cater for its population.

The Government of Rwanda is planning to borrow US$1bn to fund various infrastructure projects in the country next year. The most pressing of the development projects on line is the construction of a new Bugesera International Airport and power plants. The government was forced to borrow from the international community after foreign investors failed to fund key projects in the country. The airport will be located in southeastern Rwanda, Bugesera District and will be Rwanda’s largest International Airport when complete, serving commercial flights destined to and from the greater Kigali metropolitan area.

It will also be Rwanda’s third international airport and the country’s eighth. The new airport to be constructed in Bugesera district is aimed at addressing the rise in the number of passengers at the Kigali International Airport. The airport is currently operating beyond its capacity of 300,000 passengers per year. The airport is operating 10 times its capacity and has been expanded as a short term measure. The total cost of the construction of the airport is US$600m and the project includes construction of a 4.2 kilometer-runway, and cargo and passenger terminals capable of handling 1.8 million passengers annually.

New US$45.5m multistorey car park at Nairobi

City Hall Nairobi has announced a tender notice for the construction of a 3000 multistorey car park in Nairobi’s Central Business District. The project involves developing an AT Sunken Car Park building at a cost of US$45.5m. The project will be undertaken through a public private partnership where the Government of Nairobi County is expected to provide the land for the project, while investors will provide the funds needed. Parking slots in Nairobi’s CBD is not adequate to cater for the number of cars in the city centre. The move to construct the building was made in anticipation of the large commuter buses for the planned metro transportation system that are to start operating in the capital soon.

New Suez Canal lane in the offing

Construction of an extra 45-mile lane to be added to the existing Suez Canal has begun, to allow more ships to be using the canal each day. The announcement was made by the President of Egypt Abdel Fatah al-Sisi. This is expected to boost trade in one of the most important canals for global trade. Through the canal, ships from Europe to Asia and vice versa do not have to pass through the Southern Africa. However, the current state at the canal is that ships have occasional room to pass each other since it is a one-way traffic canal. Addition of the lane will see ship travel at both directions for less than the 101 miles long canal. The current canal is an artificial sea-level waterway creation. The addition will cut down hours spent travelling along the canal from 11 to about 3 hours.

Alstom's New g3 and DC Circuit Breaker

Alstom Grid has unveiled its latest innovations at CIGRE 2014, the biennial worldwide forum of the electrical power industry, held in Paris, France. Alstom’s experience and expertise are, once again, the creative springboard towards technological developments, which combine invention and innovation for today and tomorrow’s electrical challenges.

Technological launches this year include - g3: Alstom is the first in the world to launch a clean alternative to SF6, a gas commonly used in high-voltage equipment. The revolutionary SF6-free solution, g3 – green gas for grid – was jointly developed with 3MTM, a leader in environmentally sustainable solutions. g3 has 98 per cent less impact on global warming than SF6. With performances comparable to SF6, it is a suitable technology for the development of today’s new generation of clean highand ultrahigh voltage equipment. Alstom and RTE have already initiated a partnership to put in operation pilot equipment.

- Direct Current (DC) Breaker: In the framework of the Twenties European programme,1 Alstom has developed an ultra-fast DC Circuit Breaker, taking a major step towards creating the Supergrid, which effectively integrates large amounts of renewables and enables intercontinental energy trade. Alstom’s prototype successfully interrupted a 5200-ampere current at 160 kV with full extinction of DC in less than 5.5 milliseconds – under the real operational constraints of a highvoltage DC transmission grid.

Solar Powered Water Filtration Systems from Pure Aqua

Pure Aqua Inc, has designed and manufactured 6 solar powered reverse osmosis water purifiers commissioned for Cameroon, Africa to purify their river water into potable, drinkable water. Each one of these 6 purifiers is not only self-supported electrically through their own solar panel but can produce 8 gallons per minute a piece. Each of the six systems start by dropping a submersible pump into the river which delivers the water to a reservoir that pressurizes and sends it through a media filter for turbidity and particulate reduction. The system then sends the water through an activated carbon chamber followed by a cartridge filter which purifies the water down to 1 micron. Lastly the system pushes the water through a UV filter for any final viral disinfection resulting in completely pure, drinkable water. Pure Aqua Inc, is a Santa Ana, CA based company who, for the last 14 years, has designed and manufactured high-end industrial water treatment systems and facilities for corporate clients and municipalities around the world.

Revolutionary

Hydraulic Road Binder (HRB)

Savannah Cement, a company selling cement products in East Africa is targeting specific entry into the road sector and has started manufacturing Hydraulic Road Binder (HRB) cement. This cement will be used to stabilize road surfaces. The technology is built with the request from the Kenyan Ministry of Transport and Infrastructure. It has already been approved by the Kenya Bureau of Standards, which is a quality checking bureau of the government. The product is however being tested by the government ministry.

Denver, CO—Nokero International, LLC has announced the launch of an ultra-efficient solar light bulb, the N182, which maximizes brightness and minimizes retail cost. At twice the brightness of the previous N180 model, Nokero’s latest design utilizes the highest efficacy LED, a radically redesigned circuit board, and a cost-effective solar panel. Nokero’s launch of the N182 solar light bulb coincides with the four-year anniversary of the company, a celebration of Colorado Companies to Watch, and the Colorado Energy Expo. The product is now available to the public, after being showcased this month by LED partner Seoul Semiconductor at the world’s largest commercial lighting tradeshow, and by emerging thought leaders at the Sustainable Brands Conference. Together, Nokero and Seoul Semiconductor demonstrate that LEDs do not just provide light, but will actually change the world through an ultra-affordable product that can provide light for the 1.3 billion people without electricity.

Stabilization of roads involves the appropriate combination of water, cement and soil, with the result being a hard, durable, paving material that forms the foundation of road and airport pavements. The impact is huge for country government and public ministries using the cement for road construction, because they will save too. For instance, Kenya could save over $227 million on road construction budget, according to Ronald Ndegwa the Managing Director at Savannah. Earlier in 2014, Savannah stated that it would build a clinker plant worth over $200 million at Athi River in order to boost production. The company also has manufacturing units across sub-Saharan Africa and its production capacity is 1.5 million tonnes.

IPMAN and core investors to put up two Petrochemical refineries in Nigeria

The Independent Petroleum Marketers Association of Nigeria (IPMAN) and core investors from Peru and South America are to construct two modern petrochemical refineries in Kogi and Bayelsa States in Nigeria. The two refineries will be constructed in collaboration with Panama-based Water Carbornfield Energy Ltd. (CEL). The projects are targeted to cost about US$3bn shillings, although the CEO has said that the company will rely on economic analysis that will take place in two to four months to establish actual project cost. The Chairman of IPMAN, Bestman Inekwe, in Lokoja, also revealed this as he visited the state governor Captain Idris Wada in July this year. The refineries when completed are expected to serve Nigeria, the West and Southern parts of Africa. He further explained that, as businessmen, IPMAN are partnering with the federal government to industrialize the nation in the upstream and downstream sectors of the economy; which will also open the state to several opportunities. According to Mr. Joseph Arosemena the CEO of Water Carbon Field Limited, the refineries are expected to be completed in two years time. The company will be referred to as ‘Creek’ Refinery Company and will produce 200,000 barrel of oil per day. He also urged the state government to grant them the licence to start the project immediately to meet up with the two years expectation.

Ethiopian Airports Enterprise seeks bidders to construct Hawassa Airport

The Ethiopian Airports Enterprise (EAE) is looking for bidders who will construct the Hawassa airport. The design work was carried out by two firms and comprised of an airfield; designed by the Transport Construction Design Enterprise (TCDE), and a terminal designed by private consulting firm, Bereket Tesfaye Consulting Architects and Engineering. The design work is already complete. The designed terminal will be a five-story building that will comprise a VIP lounge, security check points and baggage handling, restaurant, kitchen and a roof terrace. Hawassa is the capital city of the Southern Nations, Nationalities and People’s Region (SNNPR). The region, in 2005, received a total of 631 thousand tourists, both local and international. The area is accessible by roads and the government seeks to capitalize on the revenue to be received, since most of the tourists visiting the area are able to afford air transport. This number is expected to double once the airport is completed. The enterprise recently awarded AfroTsion a US$29m contract for the construction of the Jinka Airport.The design of the airport was done at a cost of US$52,000.

Water efficiency can be a steamy issue for power plants

Generating power can mean the use of a diverse range of technology, from a simple coal fired facility to the latest in nuclear plants. But all have one thing in common: the need to control heat and produce steam, and this generally necessitates using large volumes of process water.

Traditionally, water is supplied to a power station from a nearby river or from the sea. However, both of these sources have issues relating to water quality. Ideally, water should be cool, clean and free from contamination, but this is seldom the case. Contamination from sea water can include Zebra Mussels, small fish and seaweed, combined with sand and high chlorine levels. River water can contain sand algae and diatom contamination. In order to condition the water to be suitable for use, traditional methods involving chemical treatment in combination with filtration plants and softeners are all employed.

In many operations, the use of water is often an accepted process cost. There is scant attention paid to ways in which better water quality can significantly improve overall plant performance and reduce operating costs. By employing modern filtration technology to some areas not normally examined as a primary application, power plants can improve both heat transfer efficiencies and sophisticated plant protection which will impact on the total generating cost and environmental impact.

Cooling Water

There is scant attention paid to ways in which better water quality can significantly improve overall plant performance and reduce operating costs.

When evaporative cooling towers or high efficiency tube heat exchangers are used for cooling, the drop in efficiency is normally put down to the pumps or fans consuming more power and accepted as ‘the norm’. As a matter of fact, efficiency is also dropping due to the reduction of heat transfer efficiency through contaminants collected in the water and deposited onto the heat transfer surfaces. Tests on typical cooling water would show that the majority of particle contamination is significantly higher below the 10 micron size than above it. It is true that the larger particles can be the primary cause of premature blockage, but the removal of the finer debris minimises the possibility of bio fouling whilst at the same time removing the larger

contamination. These elements can lead to premature tube blockage, bio fouling and or silting, all of which results in significant plant performance losses.

Effective removal of these particles can actually boost efficiency and reduce the risk of biological contamination. Side stream filtration, correctly applied to handle a rate of between 1-5% of the total volume or flow on cooling systems (the higher the side stream flow the quicker the clean-up is achieved), can be installed to remove contamination down to 0.5 micron or 2.0 micron. This approach has been shown to improve plant performance, reduce chemical costs and improve biological control.

Steam Raising

Many power plants take river water for both steam generation and cooling water make up. However the quality of water drawn from a river will vary depending on location, climatic considerations and up stream inputs (such as effluent plant and other industrial users). The use of high efficiency media filtration technology when used as a prefilter can remove contamination to less than 1.0 micron, thereby reducing the load on the conventional RO plants. This can significantly improve the feed water quality to the membrane plant often reducing the fouling factor. This leads to extended operation cycles with lower operational cleaning thereby reducing costs and increasing membrane life.

Coal Storage

Traditional coal fired power plants carry huge stocks of coal on site. During periods of heavy rain especially, the environment has to be protected from the waste run off from these coal fields as coal laden water cannot be returned to the river without the removal of the coal.

HEP projects in Africa

Beneficial or wasteful?

Africa is in dire need for power to meet growing demand, with 2 out of three sub-Saharan Africans lacking access to electricity. Africa which is currently managing 1,000 MW of additional power generation annually, will need 7000 MW of additional generation capacity each year to meet economic expansion according to the World Bank. With over 1,600 large dams around the world under construction amidst economic viability criticisms, sustainability issues, attached economic, social and environmental costs and availability of cheaper and better options such as solar and wind power, it is argued that pursuing large hydropower dam projects must be reconsidered, according to some researchers.

Researchers and scholars have found that the actual cost of large hydropower dams exceeds the budgeted amount almost always

Criticism

After continued criticisms of large dam projects, Presidents of the International Commission on Large Dams (ICLD) and International Commission on Irrigation and

Drainage (ICID) in May this year wrote to the President of World Bank Group expressing concerns on criticisms related to hydropower and water storage projects related to construction and development of large and small dams. The two presidents explained that the 50, 000 large dams and 1 million small dams around the globe played a vital role in generating 15% of cheap electricity and 80% of renewable energy, controlling floods, providing 40% of food from irrigated activities, as well as providing water to masses. Pointing out the particular case of the Inga 3 dam and that only 8% of African hydropower is exploited and 10% of land under irrigation, they argued that discontinuation of the World Bank’s initiatives to fund projects related to construction and development of large and small dams could cause “a global disaster in the near future.”

They particularly supported the World Bank’s re-engagement in developing water resources, including construction of dams as

shown in one of the World Bank’s 2013 policy document, but stated that they supported “well-run projects, to manage world water for the benefit of people, the prosperity of nations and the world.” Exactly how wellrun large dam projects are from the day of inception determines whether they become economically viable or not and whether they exacerbate related social, environmental and other costs.

Serious and diverse negative ramifications

Researchers and scholars have found that the actual cost of large hydropower dams exceeds the budgeted amount almost always, without regard to environmental, social and debt servicing costs, as well as costs related to inflation. According to a recent Oxford research in 2014 that considered cases of 245 large dams (of walls exceeding 15m high) built in 65 different countries around the world, the actual cost even run to averages of +90% higher than the budgeted amount at the time of project approvals. Considering data from across countries that have, are building, or are considering building large dams, researchers conclude that these projects take too long to complete and cannot deliver any positive risk-adjusted return unless some measures are taken. Besides, the megaprojects have a longer lead time and cannot be relied to solve urgent power problems even if they carry some benefits.

Apart from the related environmental costs associated with large dams proved by the World Commission on Dams, researchers explain that risks associated with these projects are too large to an extent of having negative ramifications on a country’s economy. The outcomes also affect the exchequer for a long time since governments must manage the negative outcomes of these projects. A well documented case is that of Brazil’s Itaipu dam whose actual costs overrun the budget by a crazy +240%, and which placed an unnecessary burden on the country’s public finances for three decades. The researchers put it very well: Itaipu dam will never pay back the money used to construct it even though it has given the much needed electricity. Considering the arguments from proponents and opponents

Grand Inga, the world’s largest hydropower scheme, is proposed for the Congo River in the Democratic Republic of Congo (DRC). It could produce up to 40,000 MW of electricity, over twice the power generation of Three Gorges Dam in China shown above.

of large dam projects, the question, therefore, is not whether large dam power projects have any benefits as many would point out, but that the overall return could be negative in nature if care is not taken.

Planning fallacy

Experts, researchers and academicians who oppose construction of large hydropower dams say that the projects are surrounded by delusion and deception in the planning phase, also called the “planning fallacy”. In this case, project promoters, including engineers, economists and statisticians, focus on the internal constituents of the specific project they are undertaking – so called the “inside view” – without considering the outcome of the previous similar projects undertaken – so called the “outside view”.

This explains why mistakes continue to be replicated across Africa and other continents in regard to building large nonprofitable hydropower dams: planners cannot care to learn from previous mistakes and lessons of related projects. Indeed, the Oxford researchers warned in April this year that the mistakes being made in relation to construction of large dams today are as worse as they were 70 years ago. A case in point is the Brazil’s effort to proceed with the Belo Monte hydroelectric dam project even after

documentation of mistakes related to the Itaipu dam project. These errors have been blamed by researchers on overreliance on heuristics and overconfidence. Optimistic proponents cite the few successful cases so they can push the projects for approval by authorities, only to

fall to the mistake. Although there have been success cases in regard to construction of large hydropower dams such as the case of Hoover dam in the USA commonly cited by proponents, of all the dams built across the globe, most of them are not economically viable.

Despite lessons learned from construction of Inga 1 and 2 dams along Congo River in a country where only about 10% have access to electricity and many continue to fight for their rights after related displacement and 85% of the electricity is used by high-voltage consumers, Africa continues optimistically buildinglarge hydropower dam projects such as the proposed Africa’s largest Grand Ethiopian Renaissance Dam (GERD) along the River Nile. Already International Rivers has termed the planning process as poor and protests have been raised by Egypt relating to the project’s possible negative impacts includingdepleting its water resources downstream. The situation for wildlife and natural habitats has not been spared. World Wildlife Fund (WWF) reveals that 60% of the 227 world’s largest rivers have been severely fragmented by dams, diversions and canals, which has led to ecosystems degradation. It adds that 40-80 million people have been displaced from their homes in dam construction-related projects.

Deception

Decision-makers, including politicians have a part to share in the blame: delusion and deception lead them to making misplaced political incentives and to misinterpret agency issues and allowing these projects. The ambition, extent of deception and lack of knowledge of non-viability of large hydropower dams is clear in the African continent considering the number of dams launched.

Simply put, those targeting to benefit from implementation of these projects deceive the unknowing government policy makers and politicians, especially so in developing countries where many leaders do not know the side effects or underestimate situations. Professor Flyvbjerg Bent of the Saïd Business School adopts a harder language to explain the mess up by planners and decision-makers;

Keban Dam in Turkey, capacity 1,330 MW, has reportedly caused flooding, displacement of people, and reduction of water supply downstream as argued by Iraq.

that the experts who forecast on hydro dam megaprojects are either optimists who ignore hard facts of project uncertainties and go ahead, or misleaders of the public seeking private, political or fiscal gain.

Alternatives

Considering the arguments from proponents and opponents of large dam projects, the question, therefore, is not whether large hydropower projects have any benefits as many would point out, but that the overall return could be negative in nature if care is not taken. How decision makers and policy makers approach the issue is important for Africa and the world as a whole.

The situation is promising considering the extent with which alternative power sources are being sought across the globe. Power Africa programme was launched by Obama last year, in an initiative that could see sub-Africa region alone add up to 10,000 megawatts into its electricity grid in the next five years. President Obama announced in the last month’s U.S. – Africa Leaders’ Summit that more $12 billion had been channeled into the project. Those projects largely dwell on setting up mega solar and wind projects, but include setting of new and expanding of existing mini-dams.

Already, the World Bank has funded an initiative to evaluate the Inga-3 dam project although it has not concluded on whether to support construction. However, China, which has applied to get involved in the construction of the Inga Dam 3 project in Democratic Republic of Congo and is currently constructing 25 dams and has proposed 26 dam projects, has approached U.S for collaboration in the construction of the Inga 3 dam.

Security systems in buildings

By Christine Achieng

Buildings around the world are built taking into consideration the safety of the people constructing them, those that will occupy them once completed and the items inside. Security in a building is paramount since an average human being spends most of their lives inside some form of construction. There are different types of buildings that require a different level of security and different systems and equipment to ensure the buildings are safe and therefore the type of security issues that must have to be considered will always depend on the kind of building being designed.

An architect must incorporate security measures while constructing the building and not install them afterwards to avoid unnecessary costs and rush to counter an identified threat after construction. This means that the contractor has to do a thorough study of the area to identify all the threats that are likely if they are to construct a building at that location. These threats vary. They may be external;

such as wild animals, thieves and vandalism, internal; such as gas leaks, radiation, fire, electrocution etc, and those that are caused by nature like floods, tsunamis, volcanic eruptions, landslides and lightning. The buildings should be made in a way that they are able to withstand any eventuality that seems to threaten the security of the building.

Magal security system

Magal security system and cyber seal Company has developed Critical Infrastructure Protection (CIP) to be used in perimeter and the access points as the last line of defense and last chance to deny intruders into areas such as industries, airports, ports, factories e.t.c. Magal security system says that every technology must be tailored to each site and therefore every solution begins with a comprehensive assessment of the costumer’s needs, existing infrastructure and operational environment.

The first basic option is Fences Only (dumb fence). This may be excellent for very low security sites; however any hostile intruder may choose the best time and cut or climb the fence un-noticed. For higher security, critical sites need a smart fence that can detect and automatically alert the guards. The range of possible technology is wide: some companies offer simple cameras, others offer smart cameras with VMD or IVA; some companies offer embedded fences like taut wire, other offer microphonic sensors as an add-on to existing fences. Magal S3 that

Opportunities abound in East Africa’s cement, concrete and construction industries

East Africa has in recent years seen exceptional growth in the construction sector, particularly around the development of new houses, multistory buildings, roads and bridges. This trend has contributed to a surging demand for building materials in particular cement and concrete.

In parts of the region cement capacity, cannot keep up with the demand whilst in other parts there is an over-supply. Whilst the under-supply may provide opportunities for a number of local cement players to increase their capacity and geographic reach, a number of new players are prospecting the market to plug the deficit whilst imported cement is still being considered as viable by the industry. (At present, the region imports about 50% of its cement).

A myriad of opportunities and challenges awaits the region ranging from quality control issues, cost

effective supply chain management and production to new technologies and techniques in the use of cement and concrete. Hypenica will be hosting the inaugural Totally Concrete East Africa conference in Dar es Salaam from 28 – 30 October 2014. The event is sponsored by Twiga Cement, Laticrete, Touchwork, Concrete Trends and Concrete.TV.

Advancing cement and concrete technology: Enhancing East Africa’s built environment

Totally Concrete East Africa will showcase how new and existing players can capitalise on the demand for increased cement production in the region, while giving users practical insight on how to increase sustainability in construction projects with techniques for service life extension, quality control enforcement in both domestic and imported cement, and reducing maintenance and repair costs over time.

Impact the future of cement and concrete in East Africa

With such a diverse attendee demographic, Totally Concrete East Africa makes it even easier to share your passion for cement and concrete with the construction industry and ignite enthusiasm for the next generation of concrete technologists, architects and engineers.

Attendees will also get to hear first-hand updates from East African government (such as Ministries of housing and public works) to find out what projects are in the pipeline and how to prepare for their respective engineering requirements and building codes.

Content highlights from the programme include:

• Totally Concrete road seminar

• East African concrete and cement leaders panel

• Maximising profit and minimising costs of the cement supply chain

• Durability, assessment and repair of concrete structures

Cranes into the next generation

By Hope Simuli

Increase in infrastructure development in the market especially high rise buildings has led to an increase in universal demand for cranes. Many developing economies have gone ahead to create markets for cranes over the last 10 years. Since cranes have become an integral part of the material lifting industry, you will find different types of cranes just to ensure that clients are able to get what will be comfortable when they are working. Cranes have been classified into three types: marine cranes, mobile cranes and fixed cranes. All these types of cranes vary depending with the lifting capacity, height and outreach with focus being mainly on higher lifting capability. Other aspects that are being put into consideration as the crane market develops and more people look for these lifting equipments include use of advanced technology in cranes, fuel efficiency cranes and greener fleets.According to research report on cranes

released by BBC Research (www.bccresearch.com), the global market for cranes is expected to grow to US $41bn by 2018. USA and Europe are markets for cranes and when it comes to Asian markets, china and India are at the forefront.

What are the Future Trends when it comes to Construction Cranes?

Since the market for cranes is growing rapidly, manufacturers have to look for better ways to ensure that they keep their cranes updated with all the proper functionality aspects. Some of the things that manufacturers have to look out for include:

• Segments

Construction companies are constantly looking for cranes hence one of the things that manufacturers have to look into is the introduction of more mobile cranes which can be moved easily during construction. Mobile cranes will also allow incorporation of wind power energy thus saving on fuel consumption.

• Lifting Capacity

Countries are going for the more advanced high-rise building hence require proper gadgets which will help in construction of such buildings. Tower cranes are becoming popular for this function not forgetting Goliath / Gantry Cranes used where bay lengths are excessive.These types of cranes are mostly used in the aviation industry, metro rail and power firms not forgetting other construction sites. The trend in lifting capacity is moving to the automated forms.

•

Timeliness and safety

Increase in demand for cranes has prompted manufacturers to come up with gadgets that save on time without

consuming so much fuel. At the same time these gadgets have to be safe to use because of the regulatory demands put in place by various governing bodies in different countries. Manufacturers are also offering training services to various individuals on how to use their lifting equipments just to ensure that the proper application is made. Experts from companies such as Electromech, advice potential clients to look out for the scope of work that the crane will be doing, spare parts for the type of crane that they choose to use and support after the sale. All this will ensure that there is customer satisfaction and efficiency when using cranes in construction work.

Water Treatment

By Hope Simuli

Waste water management has become one of the major challenges that most countries face due to the scarcity of water resources. However, the few countries that manage to deal with this issue give priority to urban centers leaving the smaller communities to look for other ways in which they can get clean water. According to statistics from the UN world water day in the year 3013, 783 million people do not have access to clean water and almost 2.5 billion do not have access to adequate sanitation Waste water treatment can only be effective if the key processes of involved in the process are taken into consideration. These involve a primary waste water treatment process where screening is done to remove any object that is present in the water.

This can be the small particles or large objects. The next level to undertake is the secondary treatment where activated sludge, filters and lagoons are used. Activated sludge’s contain bacteria which will help in the breaking down of organic substances while filters will be very effective when it comes to separation of the substances that remain in the water. Each of the process requires special equipments such as generators, different types of water pumps, water neutralizing and oxidizing filters, separators in case there is oil in the water and sludge treatment equipment.

With the scarcity of water becoming a worldwide issue waste water treatment has come into sharp focus as key to proper use of this resource. This has driven the emergence of new trends in treatment as the traditional modes are slowly fading. Technological advancement has been of great aid when it comes to new forms of treatment.

Recruitment will be done in all major cities nationwide. By doing this we shall be able to reach many customers, since we want to work with zero queues.”

By setting these funds aside, Mr Rao said, Crown Paints will be able to train at

least 200 painters, by the end of 2014. “We want to take paint to the masses that why we are training painters. Our aim is to train 3000 painters in the next three years,” he added. Since the opening of Crown Paints Showrooms in three major towns, Mr Rao revealed that the demand for designers paints and coating has enormously grown; hence the need to equip painters with relevant skills in the market. “Demand has grown and we are unable to satisfy our customers’ needs due to painter’s shortage. The demand is being catapulted by choice, since most customers are well travelled.

Before, we were selling a lot of basic paints. Currently, designers coating contributes at least 10 percent of our paints sale. Designers coating generates value, satisfaction and delight,” Mr Rao explained. Some of the designer’s coatings are armourcoat and flowcrete.

He further added, “We are laying a foundation and in the next three years, we will be looking at volumes on designers coatings. By doing this our Crown Paints brand will be growing stronger.”

Kwale Mineral Sands Project Into Production

Operations Update

Since the start of operations in October 2013, we continue to maintain an admirable safety record, however, we never allow ourselves to become complacent. All levels of management and employees must continue to work as a team to identify, report and eliminate hazards. Our employees are empowered to stop work in a dangerous environment until the hazardous situation has been rectified and to stop others working in a dangerous manner.

A huge amount of work has been completed by the Project Teams in many areas of the Project since commissioning. Modifications and de-bottlenecking are a common feature during ramp-up. Significant improvements in the performance of the Pretorius Concentrator Plant (PCP) and Mineral Separation Plant (MSP) have been achieved and structural and electrical modifications on the conveyor system and ship loader at the Likoni Shiploading Facility were completed.

The Dozer Mining Unit and the PCP are now both fully operational and performing to expectations. While ilmenite production is on track, work continues within the MSP to achieve target recoveries of high value commodities, rutile and zircon. This is the highest priority at present and the metallurgists and production personnel are fully focused in this area.

In the 2013/14 financial year 134,500t of ilmenite, 19,200t of rutile and 3,100t of zircon were produced. However, commodity prices are very depressed at present, but we hope for improved market conditions in the next few months.

Skills Transfer and Education

92% of employees are from Kenya

Our learning and development strategy is firmly aligned to our company goal to be “a creative resource company that enriches our people, our communities and our shareholders as we strive to be the pre-eminent African-focused mining company by 2021”.

Our focus is on building capability, both internally and in the external market to ensure local skills are available for the life of the mine and for the mining sector in Kenya in general. Our aim is to move to a higher level of skilled national staff with less dependence on expatriate skills.

In the external space we have programmes focused on up-skilling high school students, currently enrolled university students, trades students and graduates. Internally we have a robust plan to address technical skill gaps and programmes to facilitate the transfer of knowledge from expatriates to locals in the shortest time possible. To date, over 9,500 individual training programmes have been conducted.

The Construction industry Marks 50 Years

of the Tanzania Union

The current Ministry of Works was instituted in November, 2010 by the President of The United Republic of Tanzania Hon. Dr. Jakaya Mrisho Kikwete. It prides itself with overseeing a total road network length of 85,517 km including trunk and regional roads (28,892 km) which are under MoW while the urban, district and feeder roads with a total of 56,625 km are under Local Government Authorities. Its vision is to have a quality, efficient, cost-effective construction industry that is capable of meeting the adverse needs for safe and environmentally friendly construction, rehabilitation and maintenance of roads, buildings, as well as electrical and mechanical works and other works that

The Ministry of Works is mandated to cater for the following areas:

• Construction Policies and their implementation

• Roads.

• Bridges.

• Ferries.

• Mechanical Matters.

• Government Buildings.

• Public Works.

• Engineering and Design Works.

• Materials Laboratory.

• Performance Improvement and Development of Human Resources under this Ministry.

• Safety and Environment.

• Extra-Ministerial Departments, Parastatal Organisations, Agencies, Programmes and Projects under this Ministry.

facilitates social economic development of the country. In order to achieve this, its mission is geared to facilitate provision of economic, safe, environmentally friendly and reliable construction industry, electrical and mechanical services, government buildings that meet the needs of the public through the development and implementation of appropriate sector policies, strategies and standards.

The Ministry also sources internal and external funds for financing of various projects under it as well as supervision of axle load control and transport safety. Among its objectives, it also has HIV/AIDS infections reduction and related services improvement, as well as commitment to enhance and sustain effective implementation of the National Anti-corruption strategy.

Road networks

The Government’s ambitious objective is to ensure that all the main towns and cities are linked by tarmac roads by the end of 2017/2018. The government also aims at attracting private sector to invest into construction industry. At independence the construction scenario was indeed different with fewer roads and structures. The population at the time, according the government figures stood at 9,540,000. Today’s 40 million plus justifies construction of more roads, houses, stadia, bridges and other related facilities. The road network at the time stood at 33,600 km including 16,000 km that were called territorial and local main roads and 17,600 km district roads.

Over the last fifty years, the government has succeeded in construction of 86,472 km from a mere 33,600. At independence, the tarmac road network covered a

paltry 1,360. Currently, tarmac road network covers 6,500km and additional 11,154km are at different stages of completion. To achieve developmental goals, the government prepared its first five-year plan to develop road networks in 1964. The aim of the First Road Development plan was to build trunk and major links with the number and weights of vehicles in consideration. Major feeder roads were built while others were developed in agriculture productive areas. The first three years had two salient characteristics; development budget was increased by 75 percent and emphasis was laid on the feeder roads. The Second Road Development Plan (1969 - 1974) envisaged shortterm plans (up to 1974), medium-term (1980 to 1985) and long term (1990). The objective was to link all the regions by 1990 with all-weather roads.

Road fund

The Roads Fund and Roads Fund Board were established by Statutory Instrument No.11 of 1998 under the Roads Tolls (Amendment) (No.2) Act of 1998. The Road Fund receives funding from the following sources: fuel levies on diesel and petrol, transit fees, vehicle overloading fees, and monies from any other source at the rate to be decided by parliament from time to time. Revenue from the fuel the fuel levies accounts for more than 90 percent of the total revenue.

The Roads Fund Board disburses funds to three implementing agencies, namely, TANROADS, local authorities under Prime Minister’s office for Regional Administration and Local Government, and Ministry of Works. TANROADS currently receives 63 percent of the distributable amount after the Roads Fund Board has deducted its own administration costs, PMORALG receives 30 percent and the MOW receives 7 percent. The Road and Fuel Tolls Act instructs the RFB to collect disburse and monitor the roads fund.

Bridges

There are 4880 bridges completed by 2011 in the whole country. Among them are Kirumi, Kagera (1992), Rusumo (1974), Wami (1959), Ruvu (2008), Benjamin Mkapa (2003), Unity Bridge (2008). Included are 11 other bridges on TANZAM road, 7 on Tanga – Horohoro road 4 on Tunduma Sumbawanga roads. Bridges that are at the early stages of assessments and

construction are Kilombero, Mwatisi, Malagarasi under the support of the Republic of South Korea, Kigamboni under NSSF. The government is undertaking an ambitious plan to ease the traffic jams in the city of Dar es Salaam through construction of flyovers starting with TAZARA under JICA and constructing ring roads. Under DART, the government is in advanced stages of development funded by the World Bank.

Like other developed and developing countries Tanzania has recently opened the doors for the private sectors to participate and invest in the Roads sector under the BOT program. Several projects have been identified for BOT and some private investors have expressed interests in the same. One example is Kigamboni Bridge. This is a bridge to be located across the Indian Ocean at Kurasini area in the city of Dar es Salaam. The bridge spanning over a length of about 560 meters will connect the city centre with Kigamboni area currently accessible by ferry operations and about 56-kilometre ring road.

This project costing USD143.5 Million is on- going and is expected to be completed in June 2015 and is financed by NSSF 60 percent and Government of Tanzania 40 percent. An Egyptian Consultancy called ACE is leading this project, whose contractors are the Chinese duo of China Railway Construction Engineering Group and China Major Bridge Engineering Co. Ltd.

In another such project, Tanzania Roads Agency (TANROADS) has signed a contract with a South Korean M/S Hanil Engineering and Construction Company Limited for construction of Malagarasi Bridge in Kigoma region. Speaking at a brief signing ceremony, the Chief Executive Officer of Tanroads, Mr Ephraim Mrema,

said the 275-metre long bridge construction project will be completed in the next three years. He said the project will be financed jointly by the Republic of Korea which will contribute USD 23 million and the government of Tanzania, which will also contribute USD 33 million, totalling USD 56 million .

“The project will be implemented in two lots, which include construction of the Malagarasi Bridge and construction of 11 kilometres of two-lane Asphalt paved road” Mrema said

Ferries At independence

There were 5 hand-pulled ferries. Today, there are more than 23 ferries, clearly demonstrating the government’s effort to provide this, all-important service.

Cradlestone Mall wins coveted SAPOA award for retail development excellence Taking pole position in the retail developments category is Cradlestone Mall in Krugersdorp, developed by Sasol Pension Fund and designed by Bentel Associates International. Inspired by its setting, the landmark Cradle of Humankind was the starting point for the philosophy that underpins its design concept. Cradlestone Mall in

Krugersdorp has won the esteemed South African Property Owners Association (SAPOA) Innovative Excellence in Retail Property Development Award 2014.

The awards were announced at the 46th Annual SAPOA International Convention and Exhibition, held at the Cape Town International Convention Centre last week. Cradlestone Mall, which opened its doors in November 2013, is owned and developed by Sasol Pension Fund, Pivotal Property Fund and Retail Africa. It was designed by Bentel Associates International. The 76,000sqm super-regional mall is in the heart of Mogale City in Johannesburg’s West Rand, with a fresh retail mix and wide choice in nearly 200 shops, restaurants and services.

AndriesSchaap, General Manager Investment from Sasol Pension Fund, says: “We are delighted that Cradlestone Mall has earned such a prestigious tribute. So much has gone in to making Cradlestone Mall a success, starting with a real need for quality retail and the vision to develop a world-class mall inspired by the World Heritage Site of the Cradle of Humankind. Thousands of people have

played a role in conceiving, developing and building Cradlestone Mall. They can all be immensely proud of their contribution to the mall and winning this sought-after award.”

Inspired by its setting, the landmark Cradle of Humankind was the starting point for the philosophy that underpins its design concept while, at the same time, adhering to proven retail flow and layout. But, it isn’t only the architectural appeal that is considered in these awards. SAPOA notes recognition is based on a holistic approach which expects developments to be economically viable, to satisfy the needs of the investor and users, to be aesthetically appealing and enhance the locality in which they are situated. Schaap adds: “Cradlestone Mall’s alluring shopping, unique fresh design, easy access, entertainment, leisure and total experience all come together to create a complete leading mall package.”

The shopper appeal of this award-winning mall lies not only in its design, but in a power-house line up of retailers led by of anchor tenants including Woolworths, Pick n Pay, Checkers, Game with FoodCo, Dion Wired and the Edcon Group, as well as Food Lovers Market, which will open this year. Its positive reception has also attracted a selection of new stores which have opened in the mall since it was launched, including latest additions Lego, Baby Boom, Isabella’s Food and Cake shop, John Craig and Sunglass Hut. Plus, Dis-Chem and Virgin Active is also set to open at Cradlestone Mall before year-end.

VOID FORMERS AND PILE CASINGS

Development

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

Product Characteristics

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

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

Problem Roof Leaks

Increasing the durability of your roof

There are many reasons not to neglect your roof. Obvious or unforeseen roof problems are a pain and undoubtedly a significant expense. One of the most common is roof leaks that can cause untimely failure of the roof systems.

If you have water stains that extend across ceilings or run down walls, the cause is likely a roof leak. Roofs commonly leak due to flashing (waterproofing) details that weren’t fastened properly during installation, or underperforming flashing material. Often, wind-driven rain comes in, especially around roof windows, dormer walls and through cracks. Flashing around chimneys can rust through if it’s galvanized steel. Water penetrates these areas and works its way behind the flashing into the house.

Over a short time, small leaks can lead to big problems, such as mold, rotted battens, spoiled insulation and damaged ceilings. It is suggested to fix leaks immediately to prevent major damage to the roof structure. Being wise to the products used on your roof and the problems that may arise, is key to prevent their escalation.

Traditionally metal or lead flashing is used to seal junctions on the roof. These methods take time to install, the material is inflexible and requires an expert roofer to install it, not to mention regular maintenance thereafter. Coverland provide a high performing lead-free alternative to traditional solutions, EasyFlash abutment seal.

EasyFlash rolls are easy and quick to install made of a self-adhesive, high stretch (up to 60%) material with performance CH butyl glue for extreme adhesion to the application surface.

Applicable to all tile profiles, galvanised sheeting or metal surfaces, EasyFlash provides a solution for additional application areas, such as an apron for skylights, solar panels, walls, chimneys and other rising structures. Even under extreme weather conditions, like long-term high temperatures, heavy rain and high winds, EasyFlash increases the durability of a roof, thanks to its outstanding weather resistance. EasyFlash application includes Coverland Connection Strip, fastened securely to the upper edge of the EasyFlash to provide additional sealing against water ingress.

Advantages at a aglance :

• All weather durability for 15 years used in conjunction with Connection Strip

• Maintenance-free

• Over 50% quicker installation time

• Save more than 50% of costs over lifespan

• Can be painted with any PVA paint to match surface Available at leading hardware stores nationwide or contact
