What is a bill of quantities (BOQ)?
A bill of quantities is a list of every item of work in a construction project, each with a description, a unit, a quantity and a rate. Contractors price it to tender, and during the job it is the basis for measuring work done and raising bills.
Also called: BOQ, BoQ, Schedule of quantities.
A bill of quantities lists work (cubic metres of concrete in footings). A bill of materials lists what that work is made from (cement, sand, aggregate, steel). The first is what the client pays for; the second is what the contractor buys.
Because every bill and every variation refers back to it, the bill of quantities is also the natural structure for budgets and for cost tracking.

Where a bill of quantities exists, schedule activities and budgets link to it, so physical progress and money spent can be compared item by item.
