How to perform Impacted As-Planned Delay Analysis in Primavera P6

The Impacted As-Planned method measures the impact of the delays on the as-planned schedule. The delays are formulated as activities and added to the as-planned schedule showing the effect of each delay and demonstrating how the project is being delayed. The amount of delay equals the difference in completion dates between the schedules before and after the impacts.

How to perform Time Impact Analysis / Window Analysis in Primavera P6

A Time Impact Analysis is a method used to determine extent of impact from potential delay in construction process. This schedule analysis method involves the insertion or addition of activities indicating delays or changes into an updated schedule representing progress up to the point when a delay event occurred to determine the impact of those delay activities.

Types of Delays

Delays can be categorized in two main areas:

  • Excusable Delays
  • Non-Excusable Delays

Excusable delays occur when the affected party is allowed to claim for a time extension, compensation or both. Meanwhile, non-excusable delays are delays that the contractor or party affected will need to bear the responsibility.

We have a simple project with the Planned schedule like this:
