I;ve been everything from a Formen, Project Mamanger, Estimator, ect. The main problem with the bidding nowadays is Bid shopping from the General contractors when the Jobs not put out as a Prime. Other then that its either the bidder missed something, Bid it at cost to keep his guys working, or is plannning to make it up on extras.(bad prints). As far as Prevailing Wage . Its all the same for all contractors unless its a family business & theres several owners that well be working on the project.
Lets keep politics out of this Forum & others here please!!
This is not the place.
