Progress Measurement

Progress measurement starts after the approval of Baseline Schedule (Master Plan) by The Client/Consultant.  The project progress then to be measured based on this master plan:

1- Prepare Baseline Schedule

2- Submit this schedule for approval

3- After progress start, use this plan to measure the progress :

– By Time

– By Resource

– By Quantity

– By $ Spent

– By Weightage

Ways of Measurement:

There are many ways to measure the progress from different perspectives; each has its merits and shortcomings.  Agreement among all parties, especially the Client, must seek before measurement starts.

The list below is just a few often-used methods:

  • By time lapse (linear with time)
  • By quantity to be produced (no. of piles, penetration of sheet pile, concrete volume, etc)
  • By resource usage (manhour used Vs. time lapse)
  • By money spent (progress claim or certified payment Vs. time lapse)
  • By weightage (agreed weightage Vs. time lapse)

 

Weight age – A Comprehensive Index For Progress Measurement

The preferred way is the “weightage” – the artificial figure assigned to activities (under P3 resource), for which we can determine the overall balance of different aspects of a project.  In other words, activities taking more time to complete, or requiring more manhour, or huge sum of money incurred to achieve the event, shall be assigned more weightages.  In actual work, the original duration can be initially used as the weightage and then adjusted later on.

Example 1: The major area of work is assigned the weightage (total weightage shall be 100%).  Completion percent times the weightage is the earned weightage.  Total earned weightage is the measurement of the project progress.

Example 2: Major trades of work is assigned the weightage (the figure is immaterial.  The importance is the proportion among all trades).  The weightage of a trade over time period is determined by the programme.  The distribution may consider some standard distribution pattern.

EARNED VALUE:

Earned Value=Completion percent as of report date x Original value.

“Value” can be:

  • Duration
  • Quantity
  • Efforts made (man-hour)
  • Payment (money)
  • Weightage
