Appreciate your expert opinion on this...
For an EPC project, we have a master schedule with 3 phases of work; engineering, procurement and construction.
In our project, construction portion is using quantities as the basis for progress measurement, engineering is using the total deliverables/drawings in getting the percent complete while procurement is based on delivery of equipment/materials.
In other words, each phase has different basis of measurement. The 3 phases of work is joined together in one master schedule.
Question: What progress measurement to use in the master schedule?

Cost or manhours are typically used as a common unit of measure for performance across the 3 EPC phases. Often cost is chosen so you can use the schedule to forecast future costs & cashflow. Whereas use of manhours is arguably a better measure to weight work done.
NB: Be sure everyone agrees in advance of how you do this, because there are a number of ways of splitting the weightage.
eg: if using manhours, do you use just direct manhours, or include subby manhours? or management time?
if using cost, when is the cost of expensive procurement items claimed? on delivery? installation? commissioning? a portion claimed at each?
you use the cost as the common weightage for the three phases.
