How to define Resource Productivity in Primavera P6 and create schedule

When create a schedule, we can based on Resource Productivity to estimate duration.

For example:

  • We have a team which can cast 10 m3 of concrete per day (This is Productivity)
  • We have an Foundation which take 100 m3 concrete.
  • Duration of Foundation activity will be  100 / 10 = 10 days

Now we will do it in Primavera.

Supposed that we have a schedule like below picture:

We will do in similar way for other activities.

Now you know how to define Productivity and create schedule from it.

BONUS:

If you have more than one resource assigned to activity, the finish date of activity will be the latest finish date of all resource.

I will add 1 more resource : Backfill

And adjust the Budget Unit to 1000

The Finish date of Backfill is 20-Dec-16, later than finish date of Concrete (10-Dec-16). So the activity will finish on 20-Dec-16

And one more thing.

The Start date of Backfill can not be same as Start date of Concrete. So we will add a Lag value for Backfill.

Enter 12 days in Original Lag column.

Backfill will start on 13-Dec-16.
