Marine construction RFPs and government contracts

A marine construction RFP (request for proposals) is a notice in which a government agency asks companies to build and repair docks, piers, seawalls and marinas, with a price and a proposal sent by a deadline. Federal agencies publish them on SAM.gov as solicitations, combined synopsis/solicitations or requests for quotes; presolicitations and sources sought notices announce them earlier.
