| dc.description.abstract | Construction projects in Sri Lanka
often fail completion within the specified time
and cost allotted for the projects. Hence, cost
overrun and delays are major problems that
construction projects frequently experience.
Many stakeholder-related causes affect cost
overrun in construction projects despite their
attempt to minimize cost overrun using various
methods. Among them, there is a considerable
proportion of Contractor-related causes.
Therefore, this study attempted to find
significant Contractor-related cost overrun
factors and apposite cost controlling techniques
that can be used to minimize the likely impact of
cost overrun on building construction projects in
Sri Lanka. This study primarily focused on
completed or ongoing building construction
projects between the years 2010 to 2019 located
in Colombo District. First, a literature review was
carried out and Contractor-related cost overrun
causes and cost controlling techniques in general
were identified. Then, a questionnaire survey
was conducted among eighty professionals who
worked in building construction projects in the
Colombo district belonging to contracting
companies with above C3 level Construction
Industry Development Authority (CIDA) grade.
Sixty-two of them were responded to and
considered as valid for further analysis. The
ultimate result was obtained through the
Relative Importance Index (RII) technique, and
the results revealed ‘poor project management
skills’ as the most significant contractor-related
cost overrun cause. Besides, the results disclosed
the implementation of the labour controlling
mechanism as the most prominent cost
controlling method that can be utilized for
minimizing contractor-related cost overrun
causes. | en_US |
