Construction
industries have a poor reputation in terms of finishing projects on budget.
Nine out of ten projects normally experience cost overrun. Different causes
for cost overrun have been identified. This paper critically reviews the
literature concerning cost overrun in construction projects in different
countries to identify the main potential causes. 173 causes of cost overrun
have been found in seventeen contexts with the main potential causes being:
frequent design change, contractors’ financing, payment delay for completed
work, lack of contractor experience, poor cost estimation, poor tendering
documentation, and poor material management.

Cost Overrun in Delivery of Public Projects
in the Saudi Construction Industry: A Review

ملخص المشاركة:

Cost
overruns are endemic in the delivery of construction projects. The problem is
global. It occurs irrespective of type and size of the project, its location,
procurement method or client. The size of overruns can be as high as 200% in
some cases. Projects thus unfortunately often make the news headlines, not
for their immense socio-economic contribution to society, but for being
poorly procured. In Saudi Arabia, two-thirds of construction projects are
publicly procured by the Saudi government, which has been invested Billions
of dollars in infrastructure projects each year as part of an ambitious
strategic development agenda to shift from mainly oil dependency to
multi-source dependency. However, reports show that about 3,000 public
projects face diverse issues related to time and cost overrun. As part of an
on-going study to develop a framework for effective public procurement for
the Saudi Arabian construction industry, this paper reports the initial
findings of the causes of cost overruns in the context of the Gulf State. It
also evaluates the interface between some of the front-end loading issues in
public procurement in Saudi and their effects on project performance. A
systematic review of the existing literature on construction cost overruns,
with focus on the Saudi Arabian construction industry has been used. One of
the initial findings is that a fixed-price contract is usually used by the
client in an attempt to transfer all financial risks to the contractors. This
has the unintended consequence of creating a turbulent environment for the
delivery of the project which leads to project abandonment by contractors,
poor quality of work and substantial rework. Further work is being undertaken
to empirically verify the initial findings reported in this paper and their
generalizability for the construction industry as a whole.
