Sealed bidding

Sealed bidding is the method behind an invitation for bids: bidders submit firm, sealed prices by a deadline, the bids are opened publicly, and the contract goes to the lowest-priced responsive bid from a responsible bidder, without discussions (FAR Part 14).

It is the default for most public construction at the state and local level.
