CHAPTER ONE
INTRODUCTION
1.1 Background of the Study
The
complexity of the construction industry due to different stakeholders’
involvement makes it differ from other industries. This complexity leads
to unwanted situations like variations with their associated effects.
And presently, it is almost becoming a rare thing for a construction
project not to have variation. Most contracts these days must make
provisions for possible variations given the nature of road construction
project (Finsen et al., 1999). (Uff, 2005) further pointed out that a
clause permitting variation of works is an essential feature of any
construction contract because without it the contractor is not bound to
execute additional work or to make omissions or changes. In line with
these, the nature and approach to the conception, planning and
subsequent actualization of construction projects are dynamic, complex,
sophisticated and capital intensive in recent times. In consequence,
these projects are subjected to adequate appraisals by the sponsors on
the basis of political, social, projects relatives’ benefits,
externalities, etcetera, with a view of ascertaining the values of money
(Onwusoye, 2005). The certification for the realization of this
objection through various techniques and other implied factors by the
potential owner of the projects leads to the eventual take off of a
construction project. Therefore, design variation need to be critically
addressed as this continue to be a frequent problem that gets worse
often in construction project. Though of recent, it is a common
phenomenon for design variation to occur on construction project. But
under normal circumstance, it is possible for a complex set of drawings
and specification to be available for preparation of fully described and
accurate bill of quantities for tendering purposes. These would deplete
further charges as a result of design changes during the construction
stage.

ABSRACT - [ Total Page(s): 1 ]Variation is one of the most severe problems in the construction industry. This variation occurs in every construction project and the magnitude of these variations varies considerably from project to project. As such, the client had to spend more than what was initially estimated in most cases, sometimes, disputes and unnecessary delays occur due to variations. This study focused to investigate causes and effects of design variation in road construction project in Akwa Ibom State. The objective ... Continue reading---
