Primavera P6, Microsoft Project, Delay Analysis Tips & Tricks
1. Purpose of Constraints in Primavera P6 Date restrictions used to reflect project requirements that cannot be built into the network logic.More accurately reflect real-world aspects of a project.Provide added control of a project.Apply to the entire project or to individual activities.Commonly used project-level constraint: Must Finish ByCommonly used activity-level constraint: Start On or AfterNo...

1. Introduction 1.1. Construction Claims What is Construction Claims? A construction claim is the assertion of a right demanding either additional time or/and payment due to the result of an action. It is possible to meet construction claims in all construction projects. Why do Construction Claims occur? Clients, contractors, and subcontractors of this environment try... Continue Reading →
What is Concurrent Delay in Construction Claims? The term “concurrent delay” is commonly used to describe circumstances where different causes of delay overlap during a period of time. Concurrent delay could occur if a delay that was caused by the owner is on the same activity path or a parallel activity path as a delay... Continue Reading →
This article addresses the concepts of some 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...

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 →
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...

In the schedule update of Primavera P6, there are occasionally gaps (empty spaces) between the actual bars and the remaining bars as illustrated in picture below. The reasons and solutions for the issue are described in this article. Reason 1: Primavera P6 schedules and displays the activities on Gantt chart in a very detailed and... Continue Reading →
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 →
What is Concurrent Delay? The term “concurrent delay” is commonly used to describe circumstances where owner-caused delays and contractor-caused delays occur at the same time. In true concurrency, the owner and contractor delay events (the cause of delay) both occur at the same time and the delay caused by the delay events start and finish... Continue Reading →
After finishing Delay analysis in Primavera P6 or MS Project, we need to make a summary graphic report for high-level manager. They do not read detail report like this: They'd like to see a report like this: Summary Forensic / Delay Schedule Analysis - Summary Graphic Report Time Impacted Analysis (in Multi Base /Window) Time...

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 →
As a planner, we usually need a second monitor to be more productive. If you have an iPad, you can easily make it a second monitor. Here are the steps: On our iPad, go to App Store and search for "Duet Display". Buy this app (around 20 USD) and install it on our iPad. On... Continue Reading →
