namaste!

normally Sir, i do like this

say,

project milestone=6 months

say mobilisation =2 weeks

testing+clearance i.e project close-out= 1 momth

so, peak resource utilisation = 4.5 months



extract

fr construction drwgs= MTO or quantities

which reflects each trade

fr productivity rate (maybe from previous job/location)



at the same time

construct the cpm schedule

construct a planning sheet (which a tabulation manner consist of activities /method /ways that we planned to construct the project at site + quantity + productivity rate (reasonable productivity rate for each volume per day or per hour) + resources (manpower/machineries/gangs or team) + planned duration (resonable duration to complete the task/activity). these i normally seat down with various site team/discipline who have vast site experience, just to came up with more realistic reasonable duration.



then

i put in all the above resources/duration in cpm schedule, placed targeted completion date and run the schedule.

normally, it would gives many positve float or many negative floats, in such cases, the adjustment have to be made in duration and resources. once we get the complete cpm, then we construct whatever client want - s curve, resource histogram/loading, driving loading/material graph.



The above process normally take 1 week or less also depends on team exposure n experience and teamwork.

Dear Salah,

Once you have finished the activity list, the best thing is to site down with the Project Team (Engineer, Managers, Foremen) and discuss the activities and how much manpower they have and how much time they have to complete each activity. It is totally dependent on the project you have. Also, you can take notes of previously completed similar projects.



Best Regards,

yes Salah, it’s been a long time, I supposed you’re using P3, or is it P6 now?



you need to apply quantity surveying on this, for example: if you are dealing with steel works or structural steel fabrication, you need to calculate the total tonnage; number of joints (welded); fitting works; etc. then you can calculate your crew and relate it to your timeframe
