Project Critical Path (CP) law
“The time it takes to build an Oil & Gas facility is the time it takes to build its pipework. Pipework construction effectively starts once engineering is nearly completed. Engineering effectively starts 2 months after half the equipment have been ordered.”

Project Duration (PD) law
“The duration of piping construction cannot be reduced below a certain minimum deriving from the facility’s piping tonnage. The duration of engineering cannot be reduced below a certain minimum deriving from the number of engineering manhours”.

You will find more details in the attachment.
