Development of a Prediction Model for Time Overturns in Construction Project

Construction projects often suffer from high level of uncertainty in many fronts: time, cost, quality, safety, etc. Most of the conducted research focuses on estimating cost contingency. The factors that affect scheduling contingency and to develop a simple model that can be used in estimating the expected time contingency of a construction project. Results show that the predicted time contingency matches with 87% the estimated contingency for real projects. The developed time contingency model showed robust results. Estimating scheduling (time) contingency is a major factor in achieving a successful schedule for construction projects. It can be achieved by using mathematical techniques such as Typical pair-wise comparison. The results show that the average time contingency value is estimated as 36.78%. The developed model is verified using seven cases studies, which shows robust results (87%). This value shows that the obtained results are fairly good and acceptable. In this paper efforts are made to establish complete analysis of 20 papers published literature related to time contingency in construction projects. This paper discusses different research papers, articles, case studies that have been published in this field. There is great scope for time contingency in the construction field in future.
