How does Resource Shift Calendar in Primavera P6 work?

In Primavera P6 -> Resources window -> Units & Prices tab, there is a selection box called Shift Calendar

I’ll show how to use it in this article.

The Shift Calendar control the Price/Unit for activity, depend on what time activity start and finish.

For example, we have resource B which has different rate for different shift.

We click on Shift Calendar and select 3-shift Operations.

We select Shift 1 and enter 15 $/hour

We select Shift 2 and enter 10 $/hour

We select Shift 3 and enter 13 $/hour

To know what time does the Shift start and finish, we go to Enterprise -> Resource Shift

Select 3-shift Operations and click Modify

Now we can see :

• Shift 1 start at 00:00, finish at 08:00
• Shift 2 start at 08:00, finish at 16:00
• Shift 3 start at 16:00, finish at 00:00

We go to Activity window, let say we have 3 activities which is:

• Duration is 1 day (8 hours)
• Calendar : 7-Day Workweek (and 24 hours/day)

We assign Resource B for all 3 activities.

Now because the start and finish time of each activity is different, the resource will have different Price/Unit.

Activity Excavation start at 00:00, finish at 08:00. The Price/Unit will be Shift 1 : 15 $

Activity Steel start at 08:00, finish at 16:00. The Price/Unit will be Shift 2 : 10 $

Activity Concrete start at 16:00, finish at 00:00. The Price/Unit will be Shift 3 : 13 $

So based on the start and finish time of activity, Primavera will get the right Price/Unit for us.
