69. Factors Influencing the Construction Time and Cost Overrun in Projects: Empirical Evidence from Pakistani Construction Industry

Construction industry plays critical role in the development of any country. Construction projects in developing countries usually face the time and cost overrun, hence affecting the profit and overall performance of the contractors. This paper aims to analyze the factors influencing the time overrun and cost overrun in Pakistani construction projects. The data in this research was collected by means of questionnaire survey from 113 construction projects. Regarding the design and documentation related issues, design changes during construction and improvements to standard drawings are critical factors influencing time overrun and cost overrun. Whereas for the labor related issues, bad performance of subcontractors and nominated suppliers and poor technical performance and shortage of technical staff are found to be critical factors. Among procurement issues, material fluctuation and shortage of material is found to be critical factor. Whereas for site operation issues, problem in land acquisition is the critical factor influencing time and cost overrun.
