Tracking & monitoring is a regular process for any construction project to evaluate planned v/s actual progress deviation. Where the baselines are used as a reference to check the above. In this project the delay is primarily taken as the main focus of study and the corresponding cost implication is evaluated. Threshold features in Primavera is used for around 5 parameters in the project (Start Date Variance (Days), Finish Date Variance (Days), Schedule Variance (SV) , Cost Variance (CV) and Accounting Variance (AV) ) which will govern the progress, as well as cost .The threshold feature in Primavera helps the project manager to monitor the tracking parameters precisely by giving range of input values. This feature most widely used in large projects with different tracking units. The benefit of threshold feature in this project helps in controlling the delay with respect to a review date so as to prevent the stretching of project duration.
