The traditional general contracting delivery system is a “design-bid-build” system. In this system the owner hires a design firm, typically an architectural firm, to provide plans and specifications for competitive bidding between general contractors. The general contractor provides a bid for the entire work as shown on the drawings and according to the project specifications.
Typically the low bidder is the successful bidder and enters into a lump sum (fixed cost) contract with the owner for the work. The general contractor is the prime contractor for the project self performing certain aspects of the work and subcontracting the remainder.
The design firm provides contract administration on behalf of the owner working closely with the general contractor.
