| 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 |
