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:

First we need to change Duration type of all activity to “Fixed Units/Time”

Go to menu Enterprise -> Resources.

Create new Resource like below picture:

We will define Productivity for Concrete resource.

Select Concrete resource. Go to Detail tab -> Default Units/Time. Enter value: 10

Go to menu Project -> Activities.

Assign Concrete resource to activities.

We will change the Budget Units to 100 (This foundation need 100 m3)

We can see activity duration will change to 10 days.

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.

Now we have a more realistic schedule.
