See the picture below to understand how you can track the overall progress of the various disciplines – piping and structure.


The simple technique to evaluate overall project progress is to find out the progress of lower activities to higher activities.
=> The progress of Plant Air work – Level 3
To illustrate this to get earned progress of Plant Air, calculate the progress of lower activities - Activity A and Activity B. So, follow the steps below:
(1) Check physical progress
Imagine Activity A has two steps – Erecting the pipe and Bolt up/Joining. And, the project team has agreed to claim 50% for erecting the pipe and another 50% for bolt-up/joining. So, when erecting piping work is completed 100% of quantity, then the physical progress is 50% x 100% = 0.5 or 50%.
(1) Calculate earned hour of Activity A = 50% physical progress x 20 hours of budgeted hours = 10 earned hours
(2) Figure out earned hour of Activity B = 0% physical progress x 30 hours of budgeted hours = 0 earned hour
Then, the earned value (hour) of Plant Air piping scope is (2) + (3) = 10 hours.
You can now find out earned progress: Earned hour/Total Budget hour = 10/50 = 20%
=> The progress of Tankage and Cooling water – Level 3: use the same method done for Plant Air to get the earned hours
=> The progress of Install Piping Location – C – Level 2
1) Check the earned hour of each level 3 activities: for example - Plant Air (10 hrs), Tankage (20 hrs) and Cooling water ( 0 hrs)=> The progress of Install Piping – Area A – Level 1
2) Sum up the earned hours - 10 hrs + 20 hrs + 0 = 30 hrs
3) Check the total budgeted hour of level 2 activity - Install Piping Location – C: 120 hours
4) Calculate earned progress = > 30 / 120 = 25%
1) Check the earned hour of each level 2 activities: for example - Install Piping Location - A (200 hrs), Install Piping Location – B (80 hrs) and Install Piping Location - C ( 30 hrs)
2) Sum up the earned hours - 200 hrs + 80 hrs + 30 = 310 hrs
3) Check the total budgeted hour of level 1 activity - Install Piping – Area A: 500 hours
4) Calculate earned progress = > 310 / 500 = 62%
=> The progress of the overall project (multi-disciplines) – Level 0
1) Check the earned hour of each level 1 activities: e.g., Install Piping – Area A (310 hrs), Install Structure – Area A ( 250 hrs)That's it! Now you've got progress data. Once the planned and earned progress data are available, plot the S Curve in Excel spreadsheet.
2) Sum up the earned hours - 310 hrs + 250 hrs = 560 hrs
3) Check the total budgeted hour – piping and structure scope: 800 hours
4) Calculate earned progress = > 560 / 800 = 70%
