When grouping activities by Activity Code and the activities are not fully assigned all the Code, the summary band will show "No <<Activity Code name>>" like the following picture. In order to hide these unnecessary words, there is a workaround. Create a new code value in which the description is a blank space or a... Continue Reading →
Primavera P6: Summarize/Roll up activity duration at WBS level using duration value, not earliest and latest date
By default, Primavera P6 summarizes/rolls up activity duration at the WBS level by calculating the period from the earliest Start Date to the latest Finish Date of all activities in that WBS. In case we want to calculate the summary duration by simply adding up the duration of all activities, below are the steps. Go... Continue Reading →

Typical Delay Analysis Methods in Construction Claims
This article addresses the concepts of several typical delay analysis methods in construction claims. Why do we need Delay Analysis in Construction Claims? Because The Delay Must Affect The Critical Path The Construction Contracts often state that no adjustment to the critical milestones dates or the scheduled completion dates would be made unless the delay...

How does Primavera P6 determine a driving relationship between activities?
The Driving Relationship is determined based on the Relationship Free Float and the business rules for Driving Relationships. Relationship Free Float Relationship Free Float (Rel FF): The Free Float on the relationship. Calculated as Successor Early Start (assuming a Finish to Start relationship) - Relationship Early Finish on the predecessors' calendar. This field is computed... Continue Reading →
How does Primavera P6 determine or identify the longest path?
In Primavera P6, when we use "longest path" option to determine the critical path, the process to determine the longest path is as follows: The longest path activities are determined by reviewing the schedule backwards (starting from the last activity) through the driving relationships; If the relationship between two activities is driving, then both activities...

Primavera P6: Schedule Options – Calculate start-to-start lag from
In Primavera P6 Schedule Options, there are 2 options for "Calculate start-to-start lag from". The purpose of these option is described below. We have a simple project: Activity A has FS relationship with Activity B Activity B has SS relationship with Activity C with a lag value of 2 days. The schedule option in this... Continue Reading →
Forensic / Delay Schedule Analysis – Summary Graphic Report in 1 Page
After performing delay analysis work in Primavera P6 or MS Project, we should make a summary graphic report for high-level manager. It would be difficult to get the overview of the analysis with a detail report like the following picture: A simple bar chart or timeline would be more effective and I would like to...

How to perform Collapsed As-Built / As-Built But-For Schedule Delay Analysis in Primavera P6
Introduction An Collapsed As-Built / As-Built But-For Schedule Delay Analysis (ABBF) is a retrospective CPM schedule delay analysis technique that determines the earliest date that the required project completion activity, or various milestone activities could have been achieved but-for the owner-caused delays that occurred during the project. The amount of owner-caused delay determined from the ABBF Schedule... Continue Reading →
