Construction industry’s trust needs mending Buildings collapsing either while under construction or soon after is becoming an all too frequent occurrence and loss of life resulting from this is cause for grave concern.

Fingers are pointing at the competence – or lack – of the contractors, failure by consultants to adequately supervise projects and the lack of capacity in relevant government regulating offices.

If this had happened in the 17th century Babylon, King Hammurabi’s builders code would have demanded that if the owner of the building suffered loss of life or property, the builder was to be held fully accountable. A life for a life and a limb for a limb. The builder would also have had to rebuild the house at his cost and pay the cost for any loss of property.

This is the 21st Century and the world is more understanding but this has come at a painful price. After a flurry of press appearances condemning the incident and a quickly convened inquiry in some instances in search of a scape goat things more often than not seem to simply die way after a while. When we interviewed various professionals across Africa regarding the cause for the present malaise what emerged is that greed and corruption are the key factors causing sub-standard work to be encouraged. Developers prefer to cut corners in a bid to make savings and unwisely bypass the use of competent consultants to supervise work on site. In addition money passes hands all too frequently in order to speedily have drawings approved at local authorities office’s that are charged with this task.

It is obvious that going forward there will be need for stiffer penalties even if not as harsh as those of Hammurabi in order to deter developers and contractors from taking undue risks all to save a penny.

U.S$1.3 billion for construction of West Africa's deepest port

Additional expressway loan endorsed

Nigeria’s Federal government has taken the initiative to decongest

in

the country by approving a US$1.35billion

contract

for

the construction of a new Deep Sea Port in Lekki- Lagos State.

Council

meeting, Minister of Transport Senator Idris Umar said the project which is expected to be completed within the next four years is to be constructed under a public private partnership PPP arrangement on a concession basis for a period of 45 years after which it will revert to the federal government.

The Minister explained that the federal government has 20 percent equity in the project with Lagos state having 18.5 percent equity while private investors have 61.85 percent stake in the project. US$800 million out of the project cost is to be funded through debt financing while the balance of US$554.5 million is to be contributed by equity.

The port is designed to handle the largest vessels in the world and is expected to cover an area of 90 hectares with room for expansion and 6 km in length which will be dredged by the contractors. The port is designed to handle 4 million tonnes of cargo. The width of the channel leading to the port is put at 200 meters to be dredged to a depth of 17.5 meters with a width of 300 meters making it the deepest in West Africa.

The Nigerian Ports Authority (NPA) is expected to garner over US$9.3 billion over the 45 years period.

The House of Peoples' Representatives has approved the US$320 million loan agreement previously agreed between the Ethiopian government and the Chinese Export-Import (EXIM) Bank to finance the ongoing construction of the six-lane expressway between Adama (Nazreth) town and Addis Ababa.

The agreement made in September between the Ethiopian Roads Authority (ERA) and the EXIM Bank has two parts including US$143 million of additional finance to finish the construction of the 80 km Adama - Addis Ababa expressway. The second condition relates to the US$177 million loan allocated to finance the first part of the project, the outer Addis Ababa ring road which stretches along Lebu-Akaki-Guro.

The loan agreement, under a long-term package, is expected to be paid over after 13 years, with an annual interest rate of two percent and a seven year holiday period, as well as a 0.25 percent fee for administration costs. The ERA is the developer of the project, while the Chinese Communication Construction Company (CCCC) is the contractor, and the total cost is estimated at some US$612 million.

Mozambique US$174 million gas-fired power plant

J

apan is to fund the construction of US$174 million gas-fired power plant in Mozambique to help the Southern African nation's fast-growing economy keep up with electricity demand.

The announcement was made during Japanese Prime Minister Shinzo Abe's visit to Mozambique, part of a three-country tour of Africa, the first by a Japanese leader since 2004. Japan has also agreed to lend Mozambique US$672 million over five years as Tokyo seeks to secure access to Mozambique's rich coal and gas reserves.

Speaking during the signing of the agreement, Fernando Augusto de Sousa, the CE of Electricidade de Mocambique (EDM) said the construction of the plant will not only increase the availability and quality of electricity in the southern region of the country, but also aims to ensure a back-up to the city of Maputo.

Mozambique has seen a spike in foreign investment since it hit on huge gas reserves, but power shortages threaten the development of industry and economic growth. Power demand, which is at about 800 MW at peak times, already outstrips supply of around 700 MW in the former Portuguese colony, whose economy is expected to grow by 14 percent this year.

Cameroon

US$2 billion for 500MW solar plant Cameroon is planning to construct a US$2.2 billion, 500 MW solar plant, enough to boost generation in the country by more than 50 percent under a plan agreed by the government and a group of companies.

The country currently produces just 933 MW of power and like many countries across Africa Cameroon is aiming to expand power production to ensure the lack of supply does not further constrain economic growth. The solar plant is part of plans by Cameroon to spend six-trillion CFA francs to more than triple electricity production to 3, 000 MW by 2020 through a mix of hydro, thermal and solar projects.

Recently it revised its 2013 economic growth forecast down to 4.8percent partly blaming power cuts for missing the figure of 5.5 percent initially set for the year. A consortium led by South Africa's GSC Energy has signed a memorandum of understanding with Cameroon to develop the plant at a fee significantly less than current electricity providers.

Steven Moti, chairperson of GSC Holdings, which owns GSC energy said a feasibility study will be done with construction expected to begin within 18 months. The project will be financed through a mixture of debt and equity. Moti did not disclose how much the electricity produced by the solar project would cost saying only it would be significantly lower than current costs.

Djibouti to invest US$31million in geothermal plants In a move aimed at cutting reliance on imported electricity from neighbouring Ethiopia, Djibouti plans to invest US$31million in geothermal power plants. Djibouti, a country in the Horn of Africa with a population of less than a million people, has a peak demand of 70 MW of electricity, 65 percent of which comes through a line connecting the Djiboutian grid with that of Ethiopia.

The project, to be funded by a range of lenders such as the African Development Bank, will start in 2015, with the first phase producing 50MW and output doubling after the second phase.

Four steam wells will be drilled in the first phase. Development of the Assal geothermal field has been contracted to Reykjavik Energy Invest of Iceland.

Tanzania-Kenya multimillion-dollar highway in the offing

Lauca Dam construction commences The Angolan government plans to spend over US$4.1 million (AKZ 400 billion) in the construction of the Laúca Dam, located in northern Kwanza Norte province. The dam will have an installed capacity of 2,060 MW. This is according to the Minister of Energy and Water, João Baptista Borges.

Borges said that tunnels are being built for the diversion of the river and this will be completed by March 2014. He added that technicians are also digging tunnels to provide access for the machinery house, where equipment will be installed for the manufacture of the concrete for the dam structures. The dam is expected to start producing power from the third quarter of 2017.

The minister also said the rehabilitation works of the 180 MW Cambambe Dam will be completed by the end of 2015 and as from 2016 it will have an installed capacity of 960 MW. Concerning the modernisation of the hydroelectric facilities all over the country, the minister highlighted the rehabilitation of the Gove Dam in the central Huambo province, which is already operating .

Construction works for the proposed four lane motorway which is to connect Arusha city with Kilimanjaro International Airport (KIA) will finally commence this year. Arusha Regional Commissioner (RC), Mr. Magessa Mulongo, said the highway, which will connect the city from Sakina-Azimio section to Usa-River Township in Meru District, is to be constructed under the supervision of the East African Community (EAC).

The highway is part of the planned corridor meant to link Arusha city with Holili and Taveta border towns via Moshi and Himo, whose construction was initially supposed to be executed last year. This highway linking Arusha and Mombasa via Moshi and Voi will enhance the growing intra-trade of the region.

Basil Read awarded additional US$25 million contracts for St Helena

Ultramodern mall to elevate Kenyan town Buffalo Mall Development Ltd is set to construct an ultramodern mall in Naivasha, a popular tourist and horticultural town 90km west of Kenya’s capital, Nairobi. According to the developers, Buffalo Mall Development Ltd, the first phase of the project will be situated on a 6-hectare site and will occupy 6,090 m2.

This phase will feature a major supermarket operated by one of Kenya’s leading stores. The supermarket chain will be the anchor tenant in keeping with established practice.

“Attractive areas dedicated to dining and beverage outlets alongside a variety of leisure components, including an outdoor amphitheatre and secure children’s playground, will provide a significant draw to Buffalo Mall”, says the developer describing what customers can expect once the mall is complete. The contractor is already on site.

The project is a joint venture between British firm, Lloyd Capital Partners and a Naivasha-based investor.

ldr. Martins Kwasi Nnuro is the President of the Association of Building and Civil Engineering Contractors of Ghana (ABCECG), a position he has held since April 2012. With 34 years experience in building and construction, Bldr Nnuro can be said to have been born into the practice. Construction Review had the opportunity to interview him and learn more about his background, the role of the ABCECG and the progress the association has made under his stewardship.

Early years Bldr Nnuro’s first insights into the construction industry came courtesy of his father. He was a teacher in colonial Ghana who resigned from teaching to become a cocoa farmer, a gamble which paid off when he became a wealthy farmer owning a large acreage of cocoa plantations. Bldr Nnuro’s father would later build a 2 storey building himself assisted by some artisans. The building still stands today as a testament to good solid construction.

Later on his elder brother formed Talent Associates Ltd, a construction firm after qualifying as a Building Technologist from the Kwame Nkrumah University of Science and technology (KNUST) and with a few years of working experience with Public works Department. Nnuro joined his firm as a qualified accountant from the Accra Polytechnic in 1975 armed with a Diplomain-Business studies- Accounting option. At Talent Associates he handled the Accounts and Administration section of the firm with tasks such as paying of workers in four operating regions of the firm, namely Eastern, Volta, Central, and the Greater Accra Regions.

“I got interested in the works that were going on at the sites right away. So I started to read the drawings in relation to the actual construction. I did this with the foremen at all sites. Further to this, I borrowed some quantity surveying books and others and started reading about building and construction. Along the way I had an

opportunity to undertake courses in Building and construction and some management course. Soon I became very knowledgeable in construction activities,’’ he said. With determination and hard work, Bldr Nnuro formed Malkna Enterprises limited in 1992 and has been working very hard to grow this company to date.

President - ABCECG Bldr Nnuro before ascending to the topmost office in ABCECG presidency through dint of hard work and passion for the industry was the Vice Chairman of the Association in the Eastern Region in 2005, then a National Executive member until elected the National President in April 2012. As the President of the Association of Building and Civil Engineering Contractors of Ghana (ABCECG)his function has been to rebrand and reposition the Association in line with modern trends.

He has instituted innovative measures for membership recruitment, stepped up capacity building and encouraged professionalism in addition to putting in place capacity building from Artisanal, through supervisory to managerial levels seeking support from Government, SDF (COTVET) and other agencies for all Ten (10) Regions of Ghana.

The ABCECG is a founding member of the African Federation of Construction Contractors (AFCCA) and a member of the 12 member Executive Bureau which meets to formulate rules that govern the AFCCA. By comparison ABCECG’s outlook regionally and internationally is very commendable.

Membership of the association by local and foreign firms keeps increasing by the day. Membership strength is now about 2000. The National Secretariat has been renovated by the president to an appreciable state, increased staff and logistics and instituted effective administrative procedures.

Saving the construction industry from collapse

The increasing number of buildings collapsing while under construction or soon after construction that something urgently needs to be done.

A

By Emmanuel Onsomu ll too frequently there have been reports in the media of collapsed buildings caused by under designing in addition to bad workmanship and use of substandard building materials. This amongst other reasons to be discussed here has led to loss of life and limb not to mention the risk of financial ruin. In Kenya for instance the construction sector has piled up Ksh20 billion

Rescuers search for survivors amongst the rubble of a collapsed building in the Kariakoo district of central Dar es Salaam, Tanzania.

(US$235million) in losses due to collapsed infrastructure according to the National Construction Authority, all as a result of poor regulation.

In 2013 alone, building collapses claimed lives of more than 60 people across Africa. January 2013 saw 5 people lose their lives and scores of others injured in Kisumu, Kenya’s third largest town. At the end of March, a building under construction collapsed in Tanzania's largest city, Dar es Salaam, claiming more than 35 lives. In May, 4 people lost their lives when a building under construction in Nyagatare, some 100 km northeast of the Rwandan capital Kigali collapsed. In July, 8 people died after a twostorey commercial building collapsed in Uganda's capital Kampala. In November, at least 6 people died when a fourstorey building they were building collapsed in Nigeria's most populous city Lagos.

The West African nation is notorious for building collapses and dozens of people have lost their lives in the past. The most recent incident reported took place in November 2013 in South Africa, a country with a relatively safe record of building collapse. A roof of a three-storey February 2014

shopping mall under construction collapsed killing 2 people and injuring several others in Tongaat near the eastern coastal city of Durban. These tragic incidences tell of an industry in dire need of reform.

Construction Review interviewed various experts in the building and construction industry to seek their opinion on the above state of affairs and various issues were highlighted as the key reasons for this.

Building by-laws A laxity in the manner in which regulators enforce building by-laws has been identified as a major contributor to collapsing building phenomena and even when those responsible for flouting the laws are prosecuted it is apparent that they do not face stiff enough sentences that would act as a deterrent. In Nigeria, Engineer Mustafa Shehu, the former President of Nigerian Society of Engineers, urges the government to live up to its responsibility by penalizing any person or group that acts contrary to the law in the construction industry. Architect Ibrahim Haruna, the former president of the Nigeria Institute of Architects (NIA) also agreed with these sentiments.

Public awareness The public has also been blamed for going for the cheap option. This leads to hiring of “Quarks” who end up delivering shoddy and unfit buildings.

Architect Ibrahim Haruna, the former president of the Nigeria Institute of Architects (NIA) sees it as being a situation where everybody ascribes on to himself the knowledge of construction. Speaking to Construction Review, André Mellet (PrArch) of Mellet & Human Architects says, clients and the public should be educated that money spent on using the services of experienced professionals is to their advantage and can avoid unnecessary and costly expenditure that can occur in the event of building failure. He further calls on the architects to take the lead here and educate their clients that they have to appoint suitable professionals.

Mr. Geoff French, the former president of International Federation of Consulting Engineers (FIDIC), concurs and notes that the important role of the consulting engineer is still poorly understood resulting in selection processes dominated by price rather than quality.

Engineer Jackson Mubangizi, President of Uganda Institution of Professional Engineers echoes their sentiments and says the public doesn’t demand for professional services quite often as they should which renders professionals out of work. He says government has a role to play in promoting the use of professional engineers and correspondingly the public needs to learn to make use of professional services so as to boost the construction industry.

Construction workers look on as an excavator clears the rubble of a collapsed building in Nyagatare,Rwanda.

Building materials A building is designed and built to perform a specific function during reasonable use and stress for its intended life and it is supposed to perform this function without structural failure which is when it can no longer withstand the loads imposed on it, and collapse can occur.

The former President of (SAICE), currently Director at Iliso Consulting in Centurion and President of the Federation of African Engineering Organisations (FAEO), Dr. Van Veelen, says that although there are cases where engineers have made mistakes in the design of a structure, most of the problems arise from developers who take shortcuts and avoid paying the fee for a competent engineer, and officials who turn a blind eye when approving the plans for a building.

He adds that there are cases where a building is designed and approved for a certain number of floors but the developer later illegally adds one or more storeys. He points out that excessive loading for which the structure was not designed is wrong adding that this is especially true for retrofitting air conditioning equipment on the roof of an existing building. The developers in the Tanzanian

Dr. Van Veelen concludes that while it is true that there are disturbingly many reports about the failure of buildings, there are many thousands of buildings completed where there are no problems and one can safely say that the failures are the exceptions, rather than the rule.

14

building that collapsed violated a permit to build an apartment building with 10 floors and at the time of collapse, it had 16 completed floors, with 3 more planned for a total of 19 floors André Mellet (PrArch) of MELLET & HUMAN ARCHIECTS points out bad design by professionals as one of the causes of building collapses. Mellet says design is the responsibility of the structural engineer.

He notes that a building is designed to withstand dead load or its own weight and live loads which are the weight of persons and objects within the building as well as the weight of wind rain and hail. He says structural failure occurs should the design be wrong and a component or the structure as a whole loses its ability to carry these loads.

Andre notes that in a well designed structural system even localized failure should not result in immediate or even progressive collapse of an entire structure. The design should also conform to minimum building codes. André also lists foundation failure as one of the causes of building collapse.

The award winning architect says a well designed structure will not stand on a bad foundation, since the structure might be able to carry its loads, but the earth below might not, and cause the building to collapse. He says extraordinary loads can also lead to

collapsing of a building and are often due to natural causes like continuous heavy snowfall, hurricanes and earthquakes. He notes that a building that is supposed to stand for many years is supposed to withstand these natural causes.

André Mellet recommends that structural engineers with experience and knowledge of materials, minimum specifications, building codes and structural systems should be appointed to perform the design of a structure. Andre says that money should be spent on geotechnical studies to determine soil conditions. The engineer can then design the foundations correctly according to the building’s function and the soil conditions on site, minimizing collapse due to foundation failure.

On his part, Dr. Van Veelen concludes that while it is true that there are disturbingly many reports about the failure of buildings, there are many thousands of buildings completed where there are no problems and one can safely say that the failures are the exceptions, rather than the rule. He is however quick to point out that this does not take away the fact that there should be NO failures at all.

Concrete Waterproofing

By Torah Onyango, Eric Mong'are and Yvonne Andiva he foundation and basement walls of any building are what keep the whole structure in place transferring dead loads and live loads into the ground.

Weakening of the foundation is probably one of the most devastating things that can happen to a building next to fire or an earthquake. Technology has presented to the builder several options to carryout waterproofing. There are the traditional membranes that are applied to the surface of the concrete structure and act as a barrier keeping water out. In the past reliance was on materials such as bitumen or silicates which were problematic because adherence to the concrete was not assured meaning that over time any breaks in the adherence meant leaks popping up.

Current membranes work much better though providing extremely strong seamless barriers that keep water out.

As membranes have continued to improve overtime, new products have emerged in the market that works on the principal of

T

changing the characteristics of the concrete itself. These additives work by plugging the pores in the concrete so that water cannot ingress. The more common methods of plugging the pores are by insoluble crystals or fatty acids. The building and construction industry has recognized that in many circumstances it may be impractical to design buildings which never get wet hence paving the way for air barriers and vapor proofing.

Their use has already been legislated within the building code of some countries such as England, Canada, U.S.A, Ireland, England, Scotland and Wales.

Where, how and whether air barriers and vapor proofing should be used depends on the climate.Air movement and water vapor related problems can occur in any climatic environment. Moisture or water vapor moves into building cavities in three ways; with air currents, by diffusion through materials and by heat transfer. Of the three, air movement accounts for more than 98 percent of all water vapor movement in building cavities.

A vapor retarder and an air barrier serve to reduce this problem, but are not necessarily

interchangeable. Vapor retarders slow the rate of vapor diffusion into the thermal envelope of a structure with other wetting mechanisms, such as wind-borne rain, capillary wicking of ground moisture, air transport being equally important. Air barriers on the other hand are mostly used in above grade construction to prevent uncontrolled air leakage through the building envelope. They significantly improve building energy efficiency, indoor comfort and longevity.

A vapor barrier is any material for damp proofing that resists diffusion of moisture through wall, ceiling and floor assemblies of buildings. Technically, many of these materials are only vapor retarders as they have varying degrees of permeability. Vapor barriers are most important in cold climates where the difference in humidity between cold dry outdoor air and warm moist indoor air forces moisture through the walls and ceiling.

Vapor diffusion retarders are normally available as coatings or membranes. The membranes are technically flexible and thin materials, but sometimes include thicker sheet materials named as "structural" Vapor diffusion retarders. The vapor diffusion 16

retarders varies from all kinds of materials and keep updating, some of them nowadays even combined the functions of other building materials.

When assessing the various waterproofing solutions you need to consider ease of use so as to reduce or eliminate errors in application since in most cases the product doesn’t come with a specialist included. Cost, cost, cost is an item that can’t be ignored but don’t forget that buying on the cheap could be a false economy if the product fails to deliver on what it promises.

Hycrete's waterproofing demonstration.

To-Cradle Gold™ certified materials. Easily dosed into concrete, Hycrete combines with metallic ions supplied by the cement to form water-insoluble polymers, thus increasing concrete durability. Those polymers act in two ways : 1. Hydrophobic Pore Blocking. The polymers in Hycrete admixtures block pores in the concrete. The absorption of water in the concrete is dramatically reduced. Water and absorbed salts stay out of the concrete.

2. Corrosion Inhibition. Ionic in nature, the molecules in Hycrete admixtures also bind to the surface of any steel reinforcement in the concrete, forming passivating layers and minimizing rebar corrosion. Hycrete admixtures also bars diffusion of ions through water that does absorb into the concrete, providing an extra layer of defense against corrosive agents, giving superior rebar protection.

According to Hycrete’s International Sales Manager Randy Cooley, Hycrete products are fully available in Africa and can be purchased from their designated distributors in Nigeria and South Africa as well. Randy added that their products are suitable for the

African environment in that they provide dual protection against moisture intrusion and corrosion. As an integral, Hycrete protects the concrete from within, which accelerates the construction schedule and therefore reduces costs compared to using membranes or coatings.

Prefabricated Housing for Africa

By Torah Onyango, Eric Mong'are and Yvonne Andiva n the recent past Africa has seen an upsurge in construction of various infrastructure projects some situated in remote locations where housing for staff is inadequate or unavailable altogether. When you consider the fact that for successful completion of these projects the welfare of the construction staff must be taken into consideration, providing staff with secure, durable accommodation becomes a priority and over the years prefabricated buildings otherwise known as modular houses have come in handy in providing the solution to temporary housing for staff on building sites.

Prefabricated houses are growing in popularity and size as more options become available. These houses are built in sections at a factory and the sections are transported to the building site and then joined together by local contractors. Prefabricated houses can be used for temporary or long-term facilities such as construction camps, schools, civilian or military housing and industrial facilities. Health care facilities, sales and retail offices and fast food restaurants can also employ the use of these houses.

Recent trends show a move in the market from basic accommodation for workers in camps at construction, mining or oil facilites to the manufacture of hospitals, schools and virtually any aspect of accommodation. Africa continues to be of great focus to most manufacturers of prefabs because of the ongoing development of infrastructure in most regions. But what makes prefabricated homes so attractive, well for a start they

I

are less expensive per square foot than site built houses.

When it comes to conforming to building codes, you need not worry as prefabricated houses are normally built to conform to all building codes at their destinations. Local building inspectors can check to make sure a prefabricated home's structure meets requirements and that all finish work is done properly. It is also important to note that these houses are durable and they have the same longevity as the site-built homes.

One other merit is that as opposed to permanent built homes prefab homes can be demounted and moved from place to place with ease hence reducing accommodation problems, costs and saving time that might have been wasted in looking for rental houses. They are also light and can be setup easily and quickly to meet a client’s specifications. Prefabricated houses can be partitioned to have multiple rooms such as bathroom facilities, bedroom and kitchen.

Most people confuse modular houses with manufactured homes and are unaware of the variety of housing options that fall under the umbrella of factory assembled homes.

Manufactured houses are normally shaped like large rectangles and they are easy to identify. They come with most systems already completed such as paint and flooring with the siding or some type of exterior finish already applied.

BEA

Finance Tower

D

By Emmanuel Onsomu eveloped as Shanghai’s new central business district, Pudong with its ever-changing skyline is often seen as the commercial symbol of Shanghai. As a result, any new developments have to respond not only to market demand but are also required to contribute to the city’s visual and spatial dynamism.

TFP’s designs for the BEA Finance Tower combine elegant, contemporary aesthetics with a modern, technologically advanced building form. The striking development offers high efficiency levels and responds to China’s increasing concern for environmental protection.

BEA Finance Tower development is a grade-A office building in a prominent location in the Lujiazui commercial district of Pudong. Standing 180 metres tall, it consists of three underground levels, a 40-storey tower and a fivefloor podium structure, which is dedicated to restaurants, public facilities and support services.

Although there are view corridors of the river and the Bund, the site is set back from the waterfront and has to compete with prominent high rises, notably the Jin Mao Building, currently the tallest skyscraper in China. TFP proposed a structure that was layered into three principal forms. A central circulation and service core is flanked by two floor plates with the west wing of the building rising above the other two components. The creation of this stepped effect brings a level of clarity and directness to the building’s massing.

Each element functions independently but is bound into a singular composition by complementary materials and modularity. This adds significantly to China Global Finance Tower’s instant-recognition factor and enhances both the view potential and the building’s silhouette on the skyline. The façades react differently to the environment through orientation, materials and technology within the building envelope. Fluctuations in heat gain and loss are limited, the building’s sustainability is maximised and operational efficiency is improved. Following detailed analysis into solar insulation, four types of cladding 20

February 2014

were established, each of which is designed to deal with a specific environmental aspect. To minimise excessive solar gain and building heat load on the south-west and south-east elevations, the percentage of glazed areas is reduced, horizontal shading devices are provided and lowemissive glass is used.

Glare protection from the low-setting sun is required on the north-west side but because the principal views of the local park lie in this direction maintaining an open, glazed vista is important. To keep the views while simultaneously limiting glare, large areas of the north-west façade are glazed and vertical fins introduced to shade the interior and allow for lighting effects at night. As well as producing an elongating effect, the fins add visual interest and depth to the façade rendering at all times.

The north-east façade has neutral solar gain and is mainly glazed with low-e glass to maximise views. TFP captured the sense of the greenery being swept vertically into the building by positioning sky gardens on the various refuge floors and creating a visual link to the park from ground level upwards. The use of other energy-efficient systems was also a main intent of the design and the building has a responsive Building Management System (BMS). This controls the interior environment to achieve optimum use of energy resources and maintains the internal air temperature and air quality.

Solar collectors are set on an angled surface on the roof of the south-west block of the tower to achieve optimum performance, contribute to the lighting of the common areas and potentially pre-heat the air and water systems.

Grey-water collection from the roof is also utilised for irrigation and flushing-water purposes. During the building’s lifetime, the net aggregate of all these systems will contribute to the limitation of energy use and enhance the profile of the development as an environmentally aware and responsible contribution to the skyline of Pudong.

Most of the sales have been done off plan, underlining the faith that the buying public has in this fast growing property developer. “About 75% of our clients are mortgage buyers while the rest pay cash”, says Mr Shah, adding that the off plan method is the company’s preferred business model. Steve Kuta, who handles sales and marketing at the company, says that the trend today is for people to purchase homes that are still under construction. “Within the construction period, they are able to reduce their balances and borrow less from financiers.”

Another major project accomplished by Chigwell Holdings is Sidai Village in Athi River in Machakos County. Phase 1 of the development, consisting of 127 maisonettes, began in 2011. About 85% of the homes are already sold. Unlike Phenom, this project had its own special challenges, says Mr Shah, who manages the company with his fellow director Palkesh Shah. “As this was a new site, we had challenges, key among them, connecting to the main water lines, sewer system and electricity. We had to get water from about three kilometers away, which was a logistical nightmare.”

Phase 2 of Sidai will be redesigned in keeping with Chigwell’s practice of incorporating the latest trends in design, finishes and construction in its projects. “It’s already been about four years since we designed the original Sidai houses. Since then, new designs and internal finishes have come up and we have to incorporate these”, says Mr Shah. Chigwell’s next project was Phenom Park within the same area as Phenom Estate. “This is an ultramodern and contemporary housing development consisting of 3-storey semi detached town houses each with a servant quarter and a family room among other February 2014

Swahili Dreams Set to Stir Lamu’s Property Market Lamu, a timeless little town along the coast of Kenya, does not immediately slip into conversations about real estate investment in Kenya. But this is soon bound to change.

Features and Finishes Built in coral stone and hardwood, this beautiful building is crafted to the highest standards and reflects the best traditions of Swahili design. All external and internal finishes use creative hand-crafted design to blend ancient Swahili culture with contemporary comfort, creating harmony with the past but looking towards the future.

With its simplicity of structural forms, the architecture is evocative of the palaces of the ancient Sultans, yet maintaining a contemporary and fresh feel.

The units feature modern amenities and conservationconscious fixtures and fittings, all finished to the highest standards. Despite these modern amenities, the developer is keen to reflect the distinctive Swahili architectural legacy of Lamu. Each residence boasts magnificent views, with the interiors being typically Swahili. Main living areas are enhanced with intricate Swahili ceiling sculptures, beamed ceilings and polished cement floors.

Satellite TV and internet have been provided for.

lthough Lamu is internationally famous and is in fact a UNESCO World Heritage Site, it would have been inconceivable for investors to put in vastsums of money in real estate only a few years ago.

It was seen as a remote destination which did not help shore up investor confidence. But this timeless,laid back Swahili island where the main transport is still on donkey back and modernity seamlessly blends with 15th century styles, looks set to be the next major frontier in Kenya’s real estate boom.

In recent years, the fortunes of Lamu have been rapidly changing. The governments of Kenya, Ethiopia and Southern Sudan are in partnership to open a major transport corridor terminating at Lamu and a deep sea port is in the works. Despite the usual teething problems with such gigantic projects, the prospects of Lamu are looking bright and early bird investors have already hit the ground running.

Among these investors is Swahili Dreams Limited, who areputting up some exclusive apartments at the heart of Lamu’s Old Town. Scheduled for completionin April 2014, the development, according to the company’s management, will be a luxurious yet eco-friendly building with a complementary fusion of modern design and traditional Swahili themes.

Designed by the renowned architect Urko Sanchez to blend in with perfect harmony into the surrounding environment, Swahili Dreams is an exclusive concept of nine apartments in a three-storey building.

The units conform to the highest standards of modern luxury.

Kitchens and bathrooms boast European-style fittings and bedrooms are designed to providethe ultimate in comfort.

Fresh air naturally circulates through the living and dining areas.The finest hardwood has been used for all internal joinery. Swahili Dreams offers a beautiful indoor pool and spa, together with environmentally-friendly features such as a solar-powered hot watersystem and wind towers to catch sea breezes efficiently and keep the building comfortably cool all year round.

A Green Development Swahili Dreams is an eco-friendly development. The building has been designed to work in harmony with its

natural surroundings, minimizing its impact on the environment. An environmental strategy has been developed to promote resource conservation. Wind catch towers allow for natural ventilation. Load-bearing walls made of coral blocks and reinforced concrete slabs have been designed to reduce heat in the interior and a coloured Lamu plaster finish with an anti-fungal exterior treatment reflects the sun and reduces heat absorption.

All apartments are fitted with solar hot water systems while water consumption is reduced through the 30,000 litre underground rain water catchment. Finally, the inclusion of a bio-digester waste water treatment plant allows for recycling of grey water.

26

An Ideal Living Space No effort appears to have been spared in making Swahili Dreams the residence of one’s dreams. The developer has thought of every possible amenity for today’s discerning customers needs and blended that with traditional Swahili themes to create a stunning development. Whether buying a unit as a holiday home or as an investment, there is no likelihood of ever regretting one’s decision. And with all signs that Lamu properties will hit stratospheric prices with the changing fortunes of the town, the best time to buy is now.

Kisima Drilling EA Limited Kisima Drilling has already managed to bag an award in the coveted Top 100 Midsized Companies Survey. The Survey is an initiative of KPMG Kenya and Nation Media Group. It seeks to identify Kenya’s fastest growing medium sized companies in order to showcase business excellence and highlight some of the country’s most successful entrepreneurship stories.

“It’s God’s grace”, says Kisima Drilling’s management of their recognition. “If you maintain honesty and ethics in

borehole drilling service that has grown in leaps and bounds A scarcity of clean water and erratic supplies from authorities charged with the provision of this indispensable commodity has seen the proliferation of borehole drilling services in Kenya. Several years ago, drilling a borehole in one’s premises was considered the preserve of the rich and large organizations. The prices were prohibitively high and the number of drilling companies was also small. Due to rapid population growth especially in the urban areas, the capacity of local authorities to supply water to their residents reliably began waning. In response, developers realized that they would have to invest in boreholes for their properties in order to attract buyers or tenants as few people can put up with unpredictable water supply.

Today, many prime developments in Nairobi and other urban areas feature a borehole as one of their strong selling points. It is now practically unheard of for a developer to undertake a prime residential project without considering borehole installation.

One of the rapidly growing companies in the borehole drilling sector in Kenya is Kisima Drilling (E.A.) Limited. Established only seven years ago, the Nairobibased company has witnessed fast growth to become a formidable player in the sector. Despite its short existence,

business, you will grow”.

With their motto “Water Revolution through Right Solution, Right Cost and Committed Efforts”, Kisima Drilling has expanded its operations throughout the country with the exception of North Eastern and coastal regions.

The company aspires to be a leader in the underground water business by offering affordable charges, being dependable and serving with commitment. The company’s full range of services includes borehole drilling, borehole equipment installation and borehole rehabilitation.

Kisima Drilling’s clientele is diverse and consists of private developers, builders, hotels, horticulture/ floriculture industries, communities and churches. Others are schools, NGOs and Government organizations. The company is equipped with two rigs and has a trained workforce of 30, making it capable of rapid mobilization wherever and whenever work is available. In the years ahead, Kisima Drilling intends to have operations in most of the East Africa Community countries. “We would like to see Kisima become a public company with over 50 rigs and operating throughout the region in the next 10 years”, says the management on the company’s medium and long term plans.

Facilities and Design The facility houses four floors of lecture rooms, administrative spaces, computer labs, a library and an auditorium. These spaces are arranged around a central landscaped courtyard. Administrative offices are located at the front of the building and make up the front facade.

Learning spaces are located to either side of the courtyard with labs and conference rooms arranged along a bridge that leaps across that same central courtyard. Ablutions and services are located at the corners of the rectangular arrangement. The rear houses the main campus library on three floors with large open terraces facing a rear garden.

Crowning the back is a large hexagonal auditorium glazed on four sides and dominated by a large translucent dome in Zetech Blue.

The building has become a landmark in both Ruiru town and on the Thika highway. Its unusual shape is strengthened by an almost formal procession to its main entrance. Turning directly off the highway, one enters a long parking space with the campus' landscaped open space to one side. The events grounds also include a manicured lawn and podium. The front facing boundary wall is a testament to the fact that beauty and security can go hand in hand.

Projects • Yogi Plumbers Limited has undertaken numerous projects since inception and more are still in hand. Some of the notable ones include: • Refurbishment of Fairmont Hotels in Kenya (Mt Kenya Safari club Nanyuki). Yogi Plumbing undertook mechanical works.

• Proposed Sameer Business Park. This is a major business complex in Nairobi. Yogi carried out Plumbing, Drainage & Fire Fighting Services.

Mt Kenya Safaric Club, Yogi Plumbers undertook mechanical works here.

Kenya

here are certain jobs in a construction project that one cannot risk giving contractors of questionable competence.

Plumbing is one of them. Poorly done plumbing has been known to cause untold misery to home owners or other end users of a project. Leakages, whether of fresh or waste water, are not only an annoying inconvenience but they can also pose a health hazard. But even when armed with this knowledge, a few developers, in a bid to cut costs, employ plumbing contractors who have no training or adequate relevant experience. It is only when a building is occupied that the shortcomings begin emerging, forcing the occupants to undertake tedious and expensive repair works that may involve undoing tiles and other unpleasant and time consuming activities.

Fortunately, the market has a good number of qualified practitioners working under various registered plumbing contractors. On of these is Yogi Plumbers Limited which is one of the fastest growing contractors in Kenya. The company was established 20 years ago

by Mr J.B. Patel out of his great passion for plumbing works.

Since then, Yogi has grown tremendously and is now a big firm undertaking not only plumbing but also drainage, firefighting systems and solar products installations.

The company has adequate capacity in terms of technical personnel, machinery and other equipment to handle projects of up to Ksh500 million (approx US$ 6million). In 2013, the company was feted among the Top 100 Mid-sized Companies in the KPMG/ Nation Media Group Survey. According to the management of Yogi Plumbers Limited, the company has managed to come this far through provision of quality services to its clients and hiring only qualified staff. “Client Satisfaction First” is the company’s driving pillar. The management acknowledges that achieving the Top 100 status did not come easy. “It’s a tough journey but with our consistence and determination, it was completed”, they say.

Congratulations

Our compliments go out to Yogi Plumbers for being counted among this year's Top 100 Companies. We're proud to be associated with you.

Power Point Systems Providing Power Solutions PowerPoint Systems EA Ltd is a Kenyan company that was born out of one man’s dream in the 2002. Mr Cosmas Musyoki had a dream to start an organization that would be the leading provider of power control and renewable energy solutions. Since then, there have been strategies to increase capacity to achieve that dream.

From a company that started with two employees, PowerPoint has grown in number of employees, capacity to handle projects of various magnitude and turnover. Eleven years on, PowerPoint is optimistic that its vision is alive and in sight.

PowerPoint Systems offers a wide range of solutions that are broadly categorized into two: Solar Power Solutions and Power Control Solutions.

SOLAR POWER SOLUTIONS Solar Lighting Solutions Lighting solutions differ in size and complexity depending on the Kenya

intended application. These may vary depending on use e.g. solar street lighting, home lighting, lighting for educational institutions and health facilities. The main benefits of photovoltaic systems are that there are no monthly billing charges, electricity is generated for more than 20 years without any need for traditional fuels, solar PV systems are durable, the systems are suitable for any part of the country (e.g., underserviced areas), no noise pollution is generated, and the production of power is environmentally friendly.

Manufacturers and stockists of :

Solar Thermal/ Solar Water Heating Solar thermal is the only economically viable solar solution for users with access to grid energy. It is possible to make well above 60% savings on electricity bills by heating water using solar. Solar thermal solutions have both domestic and industrial applications.

Homes as well as hotels, schools and hospitals can benefit from the free resource that is solar. Be it for basic hot water requirements or for complex applications, PowerPoint has a solution for every need.

Solar Borehole Pumping Solutions Solar pumps offer a clean and simple alternative to fuel-burning engines and generators for domestic water, livestock and irrigation.

They are most effective during dry and sunny seasons. They require no fuel deliveries, and very little maintenance. Solar pumps are powered by photovoltaic panels and the flow rate is determined by the intensity of the sunlight. PowerPoint offers reliable and convenient water provision technologies.

La Beach A benchmark for luxury seaside Ghana

I

f you ever dreamt of experiencing the feel of sandy beaches, together with the sound of the ocean, the fresh healing breeze of sea air and peaceful ocean front living on a daily basis, then the La Beach Towers is the place to enjoy this amazing experience by simply owning a piece of Ghana’s premier beachfront real estate.

The La Beach Towers, a five-star luxury accommodation in a verdant seafront surrounding has brought the best proposition yet to Ghana’s rapidly rising real estate industry.

The development’s 198 apartment units, sitting within three 18-storey towers, offers buyers and residents luxury and comfort that is comparable only to the most respected and world-leading five star hotel brands.

The Oceanic View Tower is under construction and is expected to be completed by the first quarter of 2014. In addition, there will be additional two towers to come on board, which together bring the value of the project to US$85 million for the entire project.

Location La Beach Towers grants easy access to all the important parts of the city. Next door is La Palm Royal Beach Hotel a five star hotel, approximately 20 minutes drive away is the 38

Central Business District and Arts Centre, a direct route to the Government offices and ministries, 15 minutes to the Airport and 10 minutes to the Osu shopping district as well as numerous restaurants and places of interest.

Features The features provided by the La Beach Towers include spacious apartments with a minimum total gross floor area of 209m2 of which one has the option to own a 3 bedroom apartment, 4 bedroom penthouse or a sky villa each provided with an extra room for use as domestic staff quarters.

There is a podium top greenery that provides high class basketball and lawn tennis courts while each unit has ensuite bedrooms, fully fitted kitchens. The La Beach Towers boasts an infinity pool and a toddler pool overlooking the ocean and next to a courtyard.

The towers are located within beautifully landscaped tropical gardens on the ground and on the podium roof, each providing external green spaces for relaxation, recreation, reading and enjoyment. Residents can also wind down on the serene beach, which is only a few metres away from the towers and February 2014

accommodation in Ghana apartments. No such residential development and indeed no five-star facility in Ghana provide such access to natural expanse of the sea and the fresh ocean.

Construction Quality The development of La Beach has taken into consideration one of the most important challenges of ocean front development which is rust and corrosion which is a source of concern for most Ghanaians.

This occurs as a result of salinity of the water and the engineers and consultants were mindful by ensuring that before concrete was cast the wire was brushed brush and steel was not left exposed for any length of time, said Tony Asare, from Tekton Consult, the architect working on the project.

In addition the project used ABBM to ensure that the concrete was tested for water to prevent leaking within the units of the towers.

Even though the site had a bit of coastal protection historically, the team of engineers and consults has in place comprehensive additional coastal protection designed around 500 metres along the coast which includes a reinforcement concrete wall embedded in the ground to about 2.5 to 3 metres which eventually came to 4 or 5 metres. “So you a have a very thick wall of 300mm thick reinforced concrete that is the coastal protection. Now from an average of 5 metres above mid sea level we have elevated our site to 7 metres above mid sea level that is about 2 and half times a normal room height,’’ Mr Asare said.

Membership is still low compared to the number of consulting engineers and engineering consulting firms registered by the Engineers Registration Board (ERB). The ERB Register shows there are 280 indigenous consulting engineers and 163 local engineering consulting firms. If ACET is to speak with a stronger voice, it is imperative membership in both categories, particularly member firms, should grow to above 50 percent of all registered consulting engineers and engineering consulting firms.

This was echoed during the 2013 Annual Consultants Discourse and Cocktail held at the Golden Tulip Hotel on 26 July, 2013. This

annual event was jointly organized by the Engineers Registration Board and ACET. During the event which, for the first time was organized for and attended by consulting engineers only, nonmembers resolved to join ACET so as to enable it to speak with a stronger voice and with greater confidence. Since then the pace of admitting members into the Association has increased.

It is desirable that all consulting engineers and their respective firms join ACET. It should however, be noted that admission of membership into the Association is not done harphzardly. ACET has to maintain its reputation of having members who are trusted advisors. Hence its interest is to admit members that offer their services with integrity while adhering to professional ethics and standards. After the ACET Council approvoves the admission, the final say is with the members. Only applicants who receive “no objection” from the members join the Association.

Advantages of becoming a member of ACET Individual Members get to attend CPD programmes at reduced rates and also enjoy intangible benefits emanating from the perception that one belongs to a respectable, reputable professional association that stands for integrity and ethical conduct in professional practice.

The also receive regular information on the industry; listing in the annual ACET Directory complete with professional qualifications and areas of specialization; enhanced job opportunities as the Association links the consulting engineers with clients and/or with foreign firms that wish to associate with indigenous firms.

Networking opportunities which help members to meet their colleagues in the industry and; use of ACET logo in business cards, letter heads, etc Member firms on the other hand get to use ACET stickers on construction site signboards, the ACET logo in brochures, company profiles and other printed literature and of course the intangible benefits emanating from the perception that the firm belongs to a respectable professional association that stands for integrity and ethics in professional practice.

In addition compendia of company profiles are printed in the Annual ACET Directory along with major projects undertaken by member firms. ACET also links member firms with private sector clients that wish to procure consultancy services. FIDIC publications are also made available at member rates while young engineers working under the firms can participate in Young Professionals Forum (YPF) programmes under FIDIC ACET is growing in terms of membership. Activites of the Association have also expanded. Since January 2011 when ACET celebrated its Silver Jubilee, a lot of other milestone events have taken place. These include relocation of GAMA Secretariat to Dar es Salaam and who are now hosted by ACET. Currently membership of GAMA embraces Morroco, Tunisia, Egypt, Sudan, Ghana, Nigeria, Uganda, Kenya, Tanzania, Zambia, Malawi, Mozambique, Zimbabwe, Botswana and South Africa(GAMA is FIDIC's Group of African Member Associations).

Eskom's National Control Centre Upgrade Set to Improve Electricity Monitoring

The National Control Centre in Simmerpan, Germiston, has undergone a significant upgrade intended to demonstrate energy saving in action.

P

ower and energy are basic requirements for development and growth and governments across the length and breadth of Africa are planning major electrification projects. The South African government is no exception and Eskom Holdings SOC Limited the local utility is striving to be a pre-eminent, world class, supplier of electricity in South Africa and Africa at large.

One way Eskom is trying to be world class in its processes is evident at its National Control Centre in Simmerpan, Germiston, which has undergone a significant upgrade intended to demonstrate energy saving in action. The National Control Centre complex comprises approximately 40 buildings used for training, storage, technical services, offices and conferences.

46

The Simmerpan complex was originally South Africa’s second power station, built to supply the energy-intensive mining industry operated from 1909 to 1957.The centre used to house two national monuments- the old switch gear building and the conditioning plant. The upgrade of the multi-million national control centre monitors electricity and tries to keep the power supplies stable.

“Whatever Gauteng does, affects demand across the whole country. If you can keep Gauteng’s power managed the rest of the country is fine”, explained Robbie van Heerden, system operator general manager atEskom National Control Centre. It can be freezing in the Western Cape, and conditions there will not affect us as much.

When demand is unusually high, 90% of that load comes from Gauteng, adds Heerden.

February 2014

The Project The upgradeproject team was led by Steffanuti Stocks as the project’s main contractor, who later appointed Leading Iconic South Africa (LISA), a black woman owned company to erect the scaffolding on the project. All the scaffolding material was supplied by Layher to LISA, and this consisted of the Layher Allround access scaffolding system.

The material was delivered and erected as required because of the limited space on site.

This was possible, because of Layher’s 60 years of experience in scaffolding solutions.

Hence, Layher ensured that its Allround system enabled on site consultants to work safely and productively.

In addition, to the Layher Allround system, other solutions supplied by Layher include

The control room Inside the control room where the electricity balance is monitored and maintained, a huge screen the size of those used in a movie theatre, lists rows and rows of figures that constantly change as supply and demand data is updated dynamically. The on-the-screen lists indicate the working power stations, the amount of power being generated and amount of power being used.

The screen has a list of all the power stations on the grid. Each unit in each power station that is working and supplying power is displayed by a red dot. Units which are offline are displayed in green. At the bottom of the screen is a display of the total amount of the load and capacity available. In addition, on the right side of the giant screen, a map depicts the country’s transmission system where the frequency of the supply across the country is displayed as engineers try to keep the optimal balance between supply and demand at about 50Hz.

the Layher Protective Systems, the Layher Event System, and Layher ladders and rolling towers. Eskom generates 95% of South Africa’s electricity

and though this

amount is equivalent to 45% of all the power used on the African continent the country still has very little excess capacity.

This means the upgrade of the National Control Centre could not have come at a more opportune time given the need to a ensure adequate supply.

LAYHER SUPPORTS PROJECT AT ESKOM’S NATIONAL CONTROL CENTRE

Eskom’s National Control Centre in Simmerpan, Germiston, is currently undergoing a significant upgrade, intended to demonstrate energy saving in action.

The Eskom Simmerpan complex comprises approximately 40 buildings used for training, storage, technical services, offices and conferences.

Historically, it was South Africa’s second power station and operated from 1909 to 1957. Leading the upgrade for Eskom is Steffanuti Stocks, the project’s main contractors, who appointed L.I.S.A. (Leading Iconic South Africa) Scaffolding, a black woman owned company to erect the scaffolding on the project. Layher supplied

all the scaffolding for this project to L.I.S.A. Scaffolding, which consisted of the Layher Allround access scaffolding system.

Due to limited space on site, material had to be delivered and erected as required with short reaction and erection times on site.

Drawing on over 60 years of experience in scaffolding solutions, Layher ensured that its Allround system enabled on site consultants to work safely and productively.

By using the Layher Allround system, L.I.S.A. Scaffolding was able to deliver the required scaffolds fast and safely, with configurations from birdcages and façade scaffolds to staircases and bridges.

I do recommend scaffolding products from Layher South Africa for perfect scaffolding,” says Lisa Hadebe, managing director of L.I.S.A. Scaffolding. In addition to the Layher Allround system, other solutions supplied by Layher include the Layher Protective Systems, the Layher Event System, and Layher ladders and rolling towers. Products are produced according to the highest European standards.

Tension Structures The Soweto Theatre - Seemingly Effortless Ingenuity

T

South Africa

he iconic Soweto Theatre, in Jabulani Soweto is said to have changed the landscape of the area.

Designed by Afritects, it has been hailed as an architectural masterpiece, and is described by the architects as a "culmination of both national and global best practices in theatre design". The theatre boasts a 420-seat capacity main theatre, with two adjacent smaller theatres inviting the community in with their fun-coloured, curved shapes.

Tension Structures won the public tender to take on the significant task of erecting the tensile fabric structure which was to double up as both a covered entrance as well as an outdoor intermission area.

By proposing an alternative concept design, Tension Structures was able to offer the architects and the client a structure which saved them a third of the cost, and omitted

50

the bulk of the heavy steel structure which was in the initial design.

Instead, Tension Structures used cables which extended through the three story glass façade of the entrance hall and were secured above the open atrium. This minimised structural supports and opened up the entrance way.

The steel cables support the ridges and troughs of a wave-like fabric formation, and the position of each cable had to be predicted precisely in order to drill small holes out of the glass façade at the exact entry point of each cable.

On the edge panels, the patterned facades throughout the building were continued into the fabric by creating a tessellated pattern. A net of thinner cables was positioned within the edge panels and diamond shaped fabric pieces each one a slightly different shape and size, were carefully tensioned into each space

in the net until the fabric was wrinkle free.

The convex and concave shapes throughout the theatre match the saddle shape of each wave in the fabric. This 3D curvature permits the fabric to resist all winds, and the fabric is fire retardant and waterproof.

Despite the structure’s need for a great deal of forward planning, and the complexity of the on-site tensioning of the structure, Tension Structures was ahead of schedule and the cables fitted perfectly through the glass façade.

By day, the ambient light under the structure is comfortable on the eyes, and by night a perfect enhancer for lighting.

The early morning and evening light leaves tessellated patterns of light on the other parts of the fabric and on the building surrounds, adding to the magic of the building as the visitors approach.

Demolitions ringing a tall steel-framed buildings down into their footprints is a considerable engineering feat since it necessitates overcoming the natural tendency of such structures to topple. The demolition project can therefore be a huge undertaking, requiring a great deal of pre-planning in order to coordinate all facets of the project. Through the course of the project some detours and changes will inevitably occur, but a solid plan and direct course of activities will assist in minimizing the overall impact on project schedule, cost and liabilities.

Planning Stages If the intended use of the site is known, it is helpful to make the contractor aware of that information. The contractor’s expertise and input at this stage of the project can help with the projects success. Determining if the demolition contractor will carry the cost and responsibility of utility disconnections is key at this stage. If not, the owner should provide all disconnect documentation to the demolition contractor. If material from the project are to be reused, the contractor should be made aware as early as possible.

The ownership of the salvaged materials should be made clear and the extent of underground removals should be clearly defined.

Any hazardous materials should be determined and whether they will have environmental remediation completed by the demolition contractor or by a separate entity. Permits should be secured, alternatively it should be made clear as to which party will secure permits. In addition, expected conditions of site at completion of demolition should be clear and conveyed to the contractor prior to the commencement of the task.

The key issues during the planning phase to be taken care of as part of the planning process include fall from height, injury from fall materials, uncontrolled collapse, risks from connected services, traffic management,

hazardous materials, noise and vibration, fire and worker involvement during the process of demolition.

Demolition Technologies Demolition technologies have continued to evolve over the years in order ensure increased efficiency, cost effectiveness, improved safety. From conventional mechanical methods to pneumatic and hydraulic tools, non-explosive demolition, controlled explosives as well as remote controlled demolition systems, minimizing the overall impact on project schedule, cost and liabilities should be the top priority of the method chosen.

South Africa

B

Proper planning and execution makes all the difference

Controlled Explosive Demolition Techniques Where space and conditions permit, it is often best to use controlled explosive methods as the primary demolition technique for large, tall structures, with mechanical methods used for secondary demolition of the structure and subsequent processing of the debris. In such situations the controlled use of explosives is supremely superior to any other form of demolition, both in terms of safety and speed, as well as efficiency. It is accomplished in conventional controlled demolitions by the synchronised detonation of numerous small explosive charges, placed adjacent to support columns throughout the building.

Through precise timing of the detonations of the hundreds or thousands of explosive packages, interior structures are destroyed ahead of exterior ones, pulling the exterior walls toward the central axis in a classic controlled demolition implosion.

Effective supervision Supplied by Frontier Electronics, Brinno Construction cameras have enhanced the management of construction projects

South Africa

With the quality of finished multi-million rand construction projects in South Africa and the region increasingly under heavy spotlight, there are calls for increasing the capacity of project managers to scrupulously monitor progress on sites. But, unfortunately, it is becoming clear that human interventions do not just suffice.

Fortunately, it has been proven that the use of appropriate technology ensures that every aspect concerning a project is spot-on. One of the fool-proof ways is the application of Do-It-Yourself (DIY) Brinno Construction cameras in different periods and places for effective construction management. Brinno Construction cameras are available in South Africa through Frontier Electronics.

“With Brinno Construction Camera’s products a project can most efficiently and economically achieve its building program goals,” Charles Msweli, Frontier Electronics’ General Manager, informs Construction Review.

Massive benefits Msweli assures construction companies that they can benefit immensely from adequate deployment of Brinno Construction cameras in construction management. He cites the following as the advantages the cameras can bring to their operations: • Ensure project success (Performance) • Accelerate the physical construction (Schedule) • Reduce the cost of the project (Cost) • Compare the conceptual design with the actual physical construction (Virtual vs. Physical, Plan vs. Real) • Decrease the overall time required for planning and design (Project life cycle management) • Virtual Construction Planning • Frame the framework for the overall material resource plan ( MRP ) • Provide continuity and improve project 54

•

coordination throughout both the design and construction phases.

Provide you more continuous control of the project; you are an active team member and approve all critical decisions affecting cost and schedule.

Passes stringent tests Feedback from end-users attest that the performance of Brinno Construction cameras exceeds expectations. It has been mostly used in foundation grouting, piling and diaphragm walls but there is still wider scope of applications.
