I have built a schedule for an EPC project and the owner wants S-Curves (or general graphical charts) to show progress of particular groups of work (eg. foundation construction) against a curve generated by the approved baseline. The schedule is not resource loaded so I cannot use the resource curves. I was thinking about manually entering budgeted nonlabor units (arbitrary units based on estimated work required for each activity) and using the activity usage profile to generate the curve on a filters group of activities. I am worried about entering all of these estimated nonlabor units into schedule (just over 1300 activities) if there is a better way or if they will get lost or change when I baseline. Any suggestions would be greatly appreciated.
