Construction bidding is the process of submitting a proposal to carry out a described residential or commercial construction project for an agreed price. Bidding can occur at the construction manager, general contractor or subcontractor level. Bids by contractors for the total cost of construction are submitted to a project owner or developer who then makes decisions based on price, contractor qualifications, and other factors.
Bid Solicitation is the process of making published construction data readily available to interested parties, including construction managers, contractors, and the public. There are several services, including government entities and private data services, that allow project owners to release project details to solicit and obtain contractor bids. These services act as a gateway for project owners to release project information to a large group of contractors, general contractors or subcontractors in an attempt to solicit bids. Many of these services are subscription based or charge a flat rate for project data.AJMAL
This delivery method is similar to the Design-Bid-Build method in that design and construction are performed by different firms. Unlike the design-bid-build approach, a general contractor and an architect are selected at the project’s inception. These firms work together throughout the design phase. When design documents are complete, the final construction costs are negotiated by the general contractor through bids from subcontractors on various scopes of work.
