The impacted as-planned method of delay analysis is a technique commonly used during a construction project’s execution to forecast a delay’s effect on the project’s critical path and completion date. It is also used to model a past delay’s effect on the project completion date to address a project’s delayed finish. This delay analysis method involves the insertion or addition of activities representing delays into the baseline schedule to determine the impact of those specific delay activities on the project completion date. The impacted as-planned schedule analysis method is generally used to quantify delays for contemporaneous requests for time extensions.
In the following example, certain design team delay issues are forecasted to impact the project’s critical path activities. The as-planned scenario shows the baseline schedule’s planned critical path and the originally planned completion date, without imposing the design team delay issues. In the impacted as-planned analysis scenario, the design team delay issues are added into the baseline schedule to forecast the impacted completion date. The impacted completion date is compared to the originally planned completion date to determine the days of delay to the project’s critical path, as shown below:
