What is P6 Progress?
The P6 Progress Calculator computes actual physical progress completion % and calculates remaining duration required to complete the task scope.
Formula
Physical Progress % = (Installed Work Quantity ÷ Total Planned BOQ Quantity) × 100
Remaining Duration = Original Duration × (1 - Physical Progress %)
Variables Explanation
- Installed Work Quantity: Quantity physically surveyed on site.
- Total Planned Quantity: Total contracted BOQ volume.
- Original Duration: Planned working duration.
How to Calculate
1. Enter total planned BOQ quantity.
2. Input current site-surveyed installed quantity.
3. Input original planned duration.
4. View Physical % Complete and Remaining Duration.
Worked Example
Task: Piping Installation (2,000 meters planned, 20 days original duration).
Site Survey: 1,500 meters installed to date.
Physical % Complete = (1,500 ÷ 2,000) × 100 = 75%.
Remaining Duration = 20 × (1 - 0.75) = 5 Working Days.
Practical Construction & Project Controls Use
Used during weekly/monthly P6 schedule updates, subcontractor progress valuation, and monthly client progress reporting.
Understanding the Result
Higher actual physical progress than planned percentage indicates an ahead-of-schedule status.
Limitations & Assumptions
Calculates physical progress based on linear quantity. Nonlinear tasks (e.g. commissioning) should use milestone weighting in P6.
Frequently Asked Questions
What is physical percent complete in Primavera P6?
Physical percent complete is based on direct site measurements of installed quantities rather than elapsed time or cost spent.
How does Data Date affect progress calculation in P6?
Data Date represents the cutoff boundary separating historical actual performance from future remaining work projections.
What is the difference between Schedule % Complete and Physical % Complete?
Schedule % Complete is based on elapsed calendar time relative to baseline dates, while Physical % Complete reflects actual work done.
How is Remaining Duration updated in P6?
Remaining Duration can be entered manually by field engineers or calculated automatically based on remaining physical quantity.
Why can actual cost % complete be misleading?
Cost spending can exceed budget due to material price increases without representing true physical work completion.
