I.I BACKGROUND OF THE STUDY
Consequences of uncertainty and its
exposure in a project, is risk. In a project context, risk is the
chance of something happening that will have an impact upon objectives. It
includes the possibility of loss or gain, or variation from a desired or planned
outcome, as a consequence of the uncertainty associated with following a particular
course of action. (Deviprasadh, 2007). Risk thus has two elements: the likelihood
or probability of something happening, and the consequences or impacts if it does. Managing risk
is an integral part of good management; it is fundamental to achieving good
business and project outcomes and the effective procurement of goods and services Risk management provides a structured
way of assessing and dealing with
future uncertainly. Project risk management includes the processes concerned with identifying, analyzing, and responding to
project risk. It includes maximizing the
results of positive events and minimizing the consequences of adverse
events.” (Deviprasadh, 2007).
Project Management Institute (2004)
defines project risk as an uncertain event or condition that, if it occurs, has a
positive or a negative effect on at least one project objective, such as time, cost, scope, or quality. A risk may have one or
more causes and, if it occurs, one or
more impacts Construction projects vary in type and nature and a large number of people with professional
skills. The variations are endless, but what all projects have in common is their exposure to risk (Flanagan and
Norman, 1999).
Civil engineering is the
branch of engineering that deals with the creation, improvement,
and protection of the communal environment, providing facilities for living,
industry and transportation, including large buildings, roads, bridges, canals,
and other engineered constructions (Stark, 2008). It is characterized by
its high magnitude, uncertainties and the level of risk involved
(Seeley and Murray, 2001). Civil engineering is a professional
engineering discipline that deals with the design, construction, and
maintenance of the physical and naturally built environment, it is traditionally broken into several sub-disciplines
including environmental engineering, geotechnical
engineering, structural engineering, transportation engineering, municipal or urban engineering, water resources
engineering, materials engineering. Coastal engineering, surveying, and construction
engineering. (Oakes 2001).
Civil engineering takes place
on all levels: in the public sector and in the private sector
from individual homeowners through to international companies (ICE, 2007),
Civil engineering was first introduced as a profession in 1828 and the Royal
charter of the Institute of Civil Engineers (2007) defined civil engineering as
the art of directing the great sources of power in nature for the
use and convenience of man, as applied in the construction of roads,
bridges, aqueducts, canals, river navigation and docks, and in
the construction of ports, harbours, moles, breakwaters and lighthouses, and in the art of navigation
by artificial power for the purposes of commerce, and in the construction and application of machinery, and in
the drainage of cities and towns (ICE,
2007). Construction engineering is a civil engineering sub discipline that involves
planning and execution of the designs from transportation (Wikipedia, 2011). The
modes of transportation as identified by Lam (1999) are roadways, railways, waterways, and airways. A road is a route on land
between two places which typically has been paved or other wise improved to allow travel by some conveyance
(Wikipedia, 2011).
Cost overruns and delays are
not unusual in civil engineering works. This pattern of
risk is’ largely influenced by the financial structure of the projects (Lam,
1999).
During limes of foreign exchange and interest role
fluctuations, most conventional projects funded by direct capital injection
from the governments may be affected by cost increases in their imported
elements. The use of project finance in privatized projects also means that
lenders rely solely on the prospective income stream for repayment
of their loans. Late completion will erode the financial plan and extra interest
costs on the part of the sponsors. There are also uncertainties as to the level
and stability of income which depends on the market condition of the
product in question. In road project, land acquisition can be a slow
and expensive process especially when a long road has to go through
different municipalities or different provinces having non-standardized land resumption
procedures. Right of way disputes sometimes creep in, as is the likelihood of
treading on archeological mines and former industrial
site with contaminated grounds (Lam, 1999).
There are many examples of non-achievement of time, cost and quality of projects due to the absence of risk management techniques in project management. Therefore, the success parameters of a construction project, namely, the timely completion, staying within the specified budget, and achieving requisite performance would depend upon the capability of each party in risk management. (Perera, 2009).
