The other focusing areas are to identify Main Causes of Delay & Delay Diversification, and Delay Mitigation. This study defines the Percentage Delay parameter and the Relative Significance Index (RSI) model, which are the new concepts introduced by the author this study.The preliminary data for this research have been collected through a literature review and a questionnaire survey targeted at local contractors of Road Construction. The collected data yields a high reliability coefficient, which is 90%.This study reveals that the local road construction projects experience 56 % -88 % of average time overrun compared to the original (planned) project duration.
