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?
