Impacted As-Planned Delay Analysis : Using Primavera P6 to see combined / consolidated effect from some or all delay event

Doing delay analysis can have this situation. We have 5 delay events.

If we need to see a combined effect of delay event 1 and delay event 2, we have to create a new project and insert those delay event. Then if we need to see a combined effect of delay event 1 and delay event 3, we have to create a new project and insert those delay event. This process go on and we can end up with more than 20 projects.

Then we find out the Baseline need to make a small adjustment (for example: add 1 more relationship), we have to edit all 20 projects.

This’s gonna be crazy.

I will show you how to make a combined effect report without having to create more than 20 projects by using Multi-project model in Primavera P6.

We have a Baseline project like below picture:

For 5 Delay Event we gonna create them in 5 projects:

Now if we want to see effect of Delay Event 1 only, we open 2 projects: Baseline and Delay Event 1.

We run F9 to see effect of Delay Event 1. However we need to click Option and check “Ignore relationships to and from other projects”:

After run F9, we can see effect of delay event 1 on the Baseline:

The EOT is 15 days

Now if we want to see effect of Delay Event 2 only, we open 2 projects: Baseline and Delay Event 2.

We run F9 to see effect of Delay Event 2:

Impacted As-Planned Delay Analysis - Using Primavera P6 to see combined, consolidated effect from some or all delay event-5

The EOT is 10 days

Now if we want to see combined effect of both Delay Event 1 and Delay Event 2, we open 3 projects: Baseline, Delay Event 1 and Delay Event 2.

We run F9 to see effect of both Delay Event 1 and Delay Event 2:

Impacted As-Planned Delay Analysis - Using Primavera P6 to see combined, consolidated effect from some or all delay event-6

The EOT is 25 days.

We can do the similar process as above to see combined effect of any delay events or all delay events:
