Assessing the Impact of the Lead/Lag Times on the Project Duration Estimates in Highway Construction
Assessing the Impact of the Lead/Lag Times on the Project Duration Estimates in Highway Construction DOI: https://doi.org/10.30564/jaeser.v4i3.3383 Abstract The literature mentions multiple factors that can affect the accuracy of estimating the project duration in highway construction, such as weather, location, and soil conditions. However, there are other factors that have not been explored, yet they can have significant impact on the accuracy of the project time estimate. Recently, TxDOT raised a concern regarding the importance of the proper estimating of the lead/lag times in project schedules. These lead/lag times are often determined based on the engineer’s experience. However, inaccurate estimates of the lead/lag time can result in unrealistic project durations. In order to investigate this claim, the study utilizes four time sensitivity measures (TSM), namely the Criticality Index (CI), Significance Index (SI), Cruciality Index (CRI), and the Schedule Sensitivity Index (S...
