Bill of Quantities (BOQ)

A bill of quantities (BOQ) is an itemized list of all materials, parts, and labor with measured quantities for a project, so every contractor bidding the job prices against the same defined scope.

Unlike an informal quantity takeoff kept inside one estimating team, a BOQ is typically issued as a shared bidding document. Each line describes the work item, unit of measure, and quantity.

BOQs are standard on commercial and public work, especially where procurement rules require transparent, comparable bids across contractors.
