Bidding Process. Main Construction builds office buildings. The building generally cost between $5 million and $7 million to build, and the plumbing can cost between $300,000 and $600,00 depending on the building requirements. Therefore, Maine always sends the plumbing work out for bid before deciding on whom to use as a subcontractor. The company has had 21 projects over the last five years with $10 million dollars in plumbing contracts being sent out for bids.
