Quantity surveyors prepare the BOQ from the drawings and specification. Contractors price it at tender stage; once the contract is signed, the priced BOQ becomes the basis for measuring work done, valuing variations and building each payment certificate.
For the contractor, the BOQ is also the natural budget: each item's rate breaks down into labour, materials, plant and subcontract costs that actual costs can be compared against.
How Civova handles it
Civova imports the BOQ into a project, turns it into the project budget, and measures payment certificates and pile records against its items.
