How to Add Activities in Primavera (Part 1): Activity Type, Duration, WBS

  • Whatsapp

The following is an example of an activity table that you can create as an example (you can also do an exercise). Previously it’s a good idea to read how to add OBS, EPS, Project and WBS.

To create an activity, the first step that can be done is to go to the Activities page.

On the Activity page, click the Add button to add an activity. After that, the New Activity window will appear. The Activity ID is automatically filled with the default auto-numbering that we configured earlier (when creating the Project).

Activity ID can still be changed if needed. Continue by filling in the Activity Name field.
You can click the Finish button (fill in other data later) or continue to fill in the data by clicking the Next button.

Adding Activity Details (Step)


In Primavera, you can break down an activity into several more detailed activities. Suppose you want to break up Site Preparation activities into:

Site Preparation:

  • Coordination with Authority
  • Mobilization
  • Install Fence

You also need to divide the weight of each job that has been detailed into (example):

Site Preparation (HP1100):

  • Coordination with Authority (30%)
  • Mobilization (30%)
  • Install Fence (40%)

Total work weight 100%.

On primavera, you can divide it in the following way:

  • Click on one of the activities whose weight will be broken down; for example, click on Site Preparation (HP1100).
  • In the activity details section, select the Steps tab.
  • Click the Add button to add a Step (activity details).
  • Fill in the detailed activity name in the Step Name column. If the column does not already exist, you can add a column by right-clicking on the header of the Steps section. Click Customize Steps Columns…
