In highway construction, it is not only important to understand the factors that affect the schedule but also to evaluate their probable severity and impact on project duration. However, there is currently no standard or accepted model existing in the industry that can be used for this purpose. This paper presents a model that identifies various factors which have a potential to influence and impact the construction schedule in highway work zones. Also, a stochastic analysis of those factors is conducted by the model to determine probable changes, i.e., reduction or escalation, in the original estimated schedule for a given project. The analysis offers a revised schedule that is bound to be more meaningful and close to the expected value. The state Department of Transportation cannot only use the results to improve project scheduling but also improve the user cost calculations and decisions regarding contract types and requirements, e.g., liquidated damages, penalties, and incentives/disincentives.
