Background of
the Study
The construction industry contributes to the socio-economic
growth of any nation by improving the quality of life and providing
infrastructures such as roads, hospitals, schools, and other basic facilities.
Hence, it is imperative that construction projects be completed within the
scheduled time, within the budgeted cost, and meet the anticipated quality.
However, being a complex industry, it is faced with severe problems of cost
(Abdul-Rahman, Memon & Abd Karim, 2013).
Cost is a common problem in both the developed and
the developing nations, making it difficult to complete many projects within
budget. Being a common problem, Allahaim & Liu (2012) reported that costs affect
90% of construction projects. However, the majority of developing countries
experience cost overruns exceeding 100% of the initial budget. The argument in
the construction industry on how to reduce or totally remove cost overruns from
projects has been ongoing among built-environment professionals, project
owners, and users for the past 70 years. There is, however, no substantial
improvement or significant solution in mitigating its detrimental effects
(Allahaim & Liu, 2012).
The growing need for construction of all types
coupled with a tight monetary supply has provided the construction industry
with a big challenge to cut cost.
According to Mendelson & Greenfield (2006), the
dwindling fortune of nations economies around the world have geared up the
participants in these sectors (the clients in particular) to take up the
challenge of ensuring efficient use of their resources to obtain value for
money in terms of performance.
The total cost of
construction in normal circumstances is expected to be the sum of the following
costs: Materials, Labour, Site Overheads, Equipment/Plant, Head office Cost and
Profit but in many parts of the world particularly in Nigeria, there are other
costs. These costs according to Mbachu
and Nkado (2004) have obvious negative implications for the key stakeholders in
particular, and the construction industry in general.
To the clients, high
cost implies added costs over and above those initially agreed upon at the
onset, resulting in less returns on investment. To the end users, the added
costs are passed on as higher rental / lease costs or prices. To the consultants, it means inability to
deliver value - for - money and could tarnish their reputation and result in
loss of confidence reposed on them by clients.
To the contractors, it
implies loss of profit through penalties for non-completion, and negative word
of mouth that could jeopardize their chances of winning further contracts, if
at fault.
