Abstract

This research scrutinized the effect of time extension on construction projects which is pivotal for Pakistan. This research work identified the ten main factors, and the ninety-five sub delay factors applied to different techniques such as RII (Relative Importance Index) method, AI (Average Index) method, and the Pareto chart method. In this work, we have analyzed the data and delineated a questionnaire for the survey to collect the opinion in the different construction industries through 70 valid responses. We have also found the most effective reasons for delaying in the construction industry and recommended some key factors for the different construction industry groups to control or avoid the time extension. This work helps the construction industry to control delays in projects.
