The reasons are two-fold:
- Many subs and vendors are too use to getting very prescriptive construction documents then providing a bid which is more about counting, math and science.
- Many GCs are too use to sending out documents in exchange for a bid which is more about administrative management.
The "Big Question" that must be ultimately answered by the team is:
What must be on the drawings in the end that isn't on there now?
Subcontractors: There is a lot of opportunity in the market for the subcontractor or vendor who can understand design intent and develop a detailed conceptual estimate that integrates with the general contractor's model.
General Contractors: There is just as much opportunity for the GC's Conceptual Estimator who can create a detailed estimate for the major sub-trades including quantities and key assumptions. And the Preconstruction Manager who can then work with a select group of subcontractors to review these details with them ensuring they are aligned on the estimated pricing and scheduling. Over time this will make both parties stronger.
