A Galway company is in talks with a regional government in Nigeria to establish a factory there and build up to 5,000 modular homes for a social housing project. Some of the houses are being proposed for a new “city”, dubbed “Calas Vegas” by local officials, adjacent to the existing state capital of Calabar. The houses would be designed off-site and erected in less than a week each. Desmond Cullinane, chairman of Affordable Building Concepts International in Oranmore, confirmed his company is in discussions with the administration of Ben Ayade, the governor of Cross River State in southern Nigeria. He declined to give further details, however, as talks are ongoing. “Nothing has been concluded at this stage. But they came to see what we had to offer and they liked it. It would be a major investment, but nothing is decided yet,” he said. A spokesman for Mr Ayade also confirmed the discussions, but did not respond to a series of detailed questions about the value and scope of the project, or the timeline for its delivery. Mr Ayade, who governs an area with a population of about four million, led a trade delegation to Ireland last month, during which he met Mr Cullinane. The Irish businessman visited Nigeria two weeks later to view potential sites and further discuss the proposed deal. Three grades Mr Ayade announced locally that the modular homes would be constructed according to three different grades. He said they would be manufactured at a factory set up by Affordable Building Concepts, and erected to house poor residents “in less than three days”. The governor wants to conclude a deal as part of a plan to build three new urban centres in Cross River, including the so-called Calas Vegas. Mr Cullinane’s Asieur International, which operates in the construction industry, registered Affordable Building Concepts International as a trading name only last month. ADVERTISEMENTADVERTISEMENT The venture’s website says it has developed a patented foam cement panel it uses to build walls in its quick building method. A note from Mr Cullinane says it can erect a house in “less than five days” using the method. He says the company currently has an annual production capacity of up to 15,000 houses. The houses are built in sections, with doors and windows in place within each section before it is erected.

Understanding Building Construction Types What truck crews should know about the differences between the types of building construction & how to best ventilate fires in each The walls and roofs of Type 5 structures are made of combustible materials—most commonly wood. Both UL and NIST studies have found that Type 5 lightweight construction will fail within minutes of direct fire impingement. When confronted with a Type 5 structure, firefighters should sound the walls prior going to the rooftop. And whether operating on tile or asphalt rooftops, alternatives to rooftop ventilation should be considered if there is heavy attic involvement. Photo Tina Gianos Type 3 buildings can be of either new or old construction, and they have non-combustible walls and a wood roof. If operating on one of these buildings, firefighters should be suspect of conventionally framed materials that may be weathered, built-up roofs or roof-on-top-of-roof systems. If it’s determined that the roof is tenable, a ladder company should be able to effectively use chainsaws to ventilate the building and make the appropriate cuts based on the type of roof system.

The environment in Nigeria is exceptionally exposed to diverse natural hazards. Due to this factor, this paper investigates a material which can be substituted for wood or steel in construction. Bamboo, a natural raw material, is one of the fastest growing plants on earth. Bamboo use in construction is not new; it has been regularly utilized for building mud houses and small huts in villages for centuries. Bamboo is a durable and exceptionally flexible building material. It has been utilized for flooring, walls, roofing, concrete reinforcement, and scaffolding, is light in weight and easily transported. This paper will examine bamboo and its environmental benefits, its properties and qualities. In Nigeria, the rate of bamboo use is low; therefore, this paper will investigate bamboo and its uses in Nigeria, conceivable uses that can be embraced demonstrating its accessibility and impacts on the environment in Nigeria.

Construction workers need to be properly trained and educated on the task or job before working, which will assist in preventing injuries and deaths. There are many methods on training construction workers. One method is coaching construction site foremen to include safety in their daily verbal exchanges with workers to reduce work-related accidents. It is important that the workers use the same speaking language to assure for the best communication. Another method is that all workers know how to properly work and use electronics, conveyors, skid-steer, trucks, aerial lifts, and other equipment on the construction site. Also, equipment on the job site must be properly maintain and inspected regularly before and after each shift. The equipment inspection system will help the operator to make sure that the machine is mechanically sound and in safe operating conditions. An employee should be assigned to inspect equipment to insure proper safety is being met. Equipment should have lights and reflectors if intended for night use. The glass in the cab of the equipment must be safety glass in some countries. The equipment must be used for their intended task at all times on the job site to insure safety of the workers.

Materials management is an important element in project planning and control. Materials represent a major expense in construction, so minimizing procurement or purchase costs presents important opportunities for reducing costs. Poor materials management can also result in large and avoidable costs during construction. First, if materials are purchased early, capital may be tied up and interest charges incurred on the excess inventory of materials. Even worse, materials may deteriorate during storage or be stolen unless special care is taken. For example, electrical equipment often must be stored in waterproof locations. Second, delays and extra expenses may be incurred if materials required for particular activities are not available. Accordingly, insuring a timely flow of material is an important concern of project managers.

One of the key problems that has stalled the growth of the high rise typology in Lagos is infrastructural in nature. Even by African standards, Nigeria is recognized as having an abysmal electrical consumption rate per capita (National Kwh per capita). Nigeria also has a low percentage of urban piped water access, particularly trailing behind all other countries in the list above, with the exception of Angola. Economy Where Lagos and Nigeria are doing quite well, is however in economic terms. The growth rate of Nigeria is well above global and African averages and ahead of that of Kenya, Angola, South Africa and Egypt for the projected period of 2015-2019. The ROI is also quite high in Nigeria and one of the key elements of this can be found in rental yields. The prime yield in Lagos for example, is only significantly lower than Luanda in the list above. Lagos is the economic heartbeat of Nigeria, but it should be noted that as a percentage of national population, other centres in Africa such as Luanda, Cairo, Abidjan and Nairobi are more crucial centres for their respective countries. Therefore these cities represent a disproportionate manifestation of their respective nation’s urban output. Built Environment One cannot or should not have an intellectual discussion about high rise proliferation, without considering the physical aspects. In real terms, Lagos needs high rise constructions. It has the highest density among the major Metropolitan areas in Africa, according to many list. In this list above that we compiled, it trails only slightly behind Abidjan. Urban density is high and thus land prices are extremely costly in many places. High rises are necessitated by its physical reality. Structural FrameworkNaturally, Lagos trails behind the South Africa centres due to their enhanced infrastructural systems and the ease of conducting business in Africa’s most industrialized nation. However, it is a little puzzling that Lagos trails behind the East African centres of Nairobi and Dar es Salaam. One explanation could be found in the historical significance of these two centres, another appropriate finding however lies in the improved service provisions of these East African cities and also in the structural framework of Dar es Salaam (Tanzania). The Unit TItles Act of 2008 (Tanzania) is more comprehensive and less restrictive than Nigeria’s Land Use Act , i.e. the LUA. These acts, effectively allow individual owners to own part of a building (unit). This can also be described as a strata title. Giving ownership to multiple owners, allows the synthesis of service provision and fuels the growth of dense developments, via multiple investors. The difference between Tanzania and Nigeria however, is in the level of restrictiveness. For example in Tanzania the entitlement of unit ownership can also extend to common areas within a building (such as lifts, lobbies, driveways), whereas in Nigeria, owners are not entitled to interest over these areas. Consequently we see a market in Tanzania that is easier to invest in and operate in and this is to an extent a factor in dense urban growth. Historical Legacy and Future Anticipation When considering the historical legacy of Lagos; as perhaps the only notable city in Africa to “Abandon” the imprint of its traditional CBD – the lack of structure and organization in Lagos is amplified even further. Victoria Island, Ikoyi and Lekki do not have a history of commercial organization and direction and thus, this also restricts the growth of densification. The Lagos State Government itself has zoned many areas of these communities and in such areas, development is restricted to 15 Floors or even below. Other Africa centres do have parallel urban districts to rival their historic centres, such as Westlands in Nairobi or Sandton in Johannesburg. However these areas have not emerged to the detriment of the historical cores, as is the case in Lagos. Lagos is a city that is restricted by its past; the failure to consolidate on the gains of Lagos Island, but it is also hanging in the balance of the Eko Atlantic phenomenon. Densification is heading the way of Eko Atlantic City and it is believed that a lot of investors are anticipating the area as the prime choice for future expansion.

 

Cost of steel building construction in Nigeria

At the beginning of the 20th century, materials with better performance and durability were introduced, for example, reinforced concrete, steel, plastics, and metal (Taylor, 2013). Ibn-Homaid and the report of UNCHS found that building materials remain the most significant input in project development and play a very important role in the delivery of construction projects. Buttressing this view, Jagboro and Owoeye and Idoro and Jolaiya find that building materials alone account for 50% to 60% of project cost and control about 80% of its schedule. One of the major constraints in the Nigerian construction industry today has been the rapid inflation in the cost of the building materials. Windapo, Ogunsanmi, and Iyagba observed that the situations arising from the rapid increase in the cost of building materials may degenerate to acute shortages of housing with the millions of middle- and low-income families being priced out of the market for home ownership all across Nigeria. According to Mansfield, Ugwu, and Doran and Obadan , government policies set the economic environment in which all sectors operate including the building materials sector. Dlakwa and Culpin and Adekoya identified government fiscal policies as one of the factors affecting the cost of building materials in the Nigerian construction industry. However, findings of other researchers, Jagboro and Owoeye ; Mojekwu, Idowu, and Sode ; and Idoro and Jolaiya , concluded that factors such as the change in government policies and legislations, scarcity of building raw materials, fluctuation in the cost of fuel and power supply, inadequate infrastructural facilities, corruption, fluctuation in the cost of plant and labor, seasonal changes, fluctuation in the cost of transportation and distribution, political interference, local taxes and charges, fluctuation on cost of raw materials, fluctuation in the interest rates and the cost of finance, the inflation, and fluctuation in the exchange rate of Naira were many of the recipes for the rising cost of building materials in Nigeria. Implications of Rising in the Cost of Building Materials The general direction at which prices of building materials are increasing in Nigeria was as the result of the combined effects of high interest rates, devaluation of the Naira, inflation, and non-effective distribution network of the materials (Ogu & Ogbuozobe, 2001; Oladipo & Oni, 2012). According to Mojekwu et al. , the Nigerian Government curtailed activities in cement business when it banned the importation of Portland cement in the country between 2003 and 2007. The study also found that although the restraining of the importations was done to protect local manufacturer but then the local manufacturer were not able to produce enough cement that could measure to the demand and as such, the action contributed to the rising cost of the product. However, Jagboro and Owoeye and Aibinu and Jagboro noticed that increase in the prices of building materials has multiplier effects on the industry as it leads to fluctuation in construction costs and the eventual abandonment of projects. Other implications such as completion at the expense of other projects, delay in progress of project works, other valuable projects not being commissioned, rate of employment of construction workers, poor workmanship as a result of the use of low-quality local materials, and inhibited innovations in construction methods were identified by Elinwa and Buba ; Idoro and Jolaiya ; Okpala and Aniekwu ; Oladipo and Oni ; and Windapo et al. as the possible implications of the rising cost. Inhibited innovations in construction methods and material research Egan’s report found that the very low and unreliable rate of profitability within construction is an obstacle to sustainable healthy development. The report was of the opinion that increasing financial pressure are bound to be on contractors when initial budget figures become completely unrealistic and concluded that the situation will damage the industry and jeopardize its existence Xiao and Proverbs also argued that construction companies have a social responsibility to provide staff training, maintain a high level of health and safety of its workers, and invest in research and development to facilitate continuous improvement in technology and management. However, inflation in the cost of building materials had resulted in low and unreliable rate of profitability, and this has affected the performance of the industry in the area of innovations in construction methods and material research. Fluctuation in construction costs Maintaining steady cost projection on construction projects had been an issue of serious concern both to the client and project contractors. Azhar, Farooqui, and Ahmed noticed that the basic reason of cost overruns is that most contractors quote prices based on their projected estimates; unfortunately, the prices change so quickly that the initial budget figures become completely unrealistic.

The fatal collapse happened after heavy rains in the early hours of Tuesday in the south-eastern district of Lekki, which is home to some of the most expensive real estate in the city. Leki, Lagos, Nigeria Lekki, made up of sprawling estates of gated communities with US-style suburban homes, has developed rapidly in recent years into a preferred location for wealthier Nigerians and expatriates. Some detached houses can sell for millions of dollars. Building collapses happen frequently in densely populated areas of Lagos, which is home to 20 million people. Poor workmanship and materials, and a lack of official oversight, are often blamed. But collapses are rarer in wealthier districts. The Lagos state government said in a statement that preliminary reports indicated work on the building was illegal. “The collapsed building was served contravention notice for exceeding the approved floors” and had been sealed by the Lagos building authorities before it collapsed, the government said. But the owners of the building and promoters of the Lekki Gardens development, Lekki Worldwide Estate Limited, “criminally unsealed the property and continued building beyond the approved floors”. Lekki Gardens confirmed in a statement that construction had stopped in January “over reported structural defects” but made no mention of work having resumed. It added: “Investigation is already under way to ascertain the identities of those affected as it is not company policy for site workers to take shelter in uncompleted buildings.” The addition of floors without proper planning approval was ruled to have been a factor in the collapse of a church guesthouse in Lagos in September 2014.
