There are currently no standard or accepted methods in the construction industry to calculate the probable impact of indirect cost factors on the schedule of highway work zone projects. This paper presents a model for stochastic analysis of factors affecting construction schedule in highway work zones and determination of probable changes, i.e., reduction or escalation, in the original estimated schedule for a given project. Also, three case studies from the Indiana Department of Transportation are illustrated in this paper in order to show the applicability of the model as a forecasting tool for predicting schedule changes on state Department of Transportation projects.
