Work package bill of quantities
A bill of quantities (sometimes referred to as a 'BoQ' or 'BQ') is a document, typically prepared by a cost consultant (often a quantity surveyor), that provides measured quantities of the items of work identified by the drawings and specifications in the tender documentation for a project. It is issued to tenderers to allow them to prepare a price for carrying out the works.
According to NRM2, RICS new rules of measurement, Detailed measurement for building work, there are three main breakdown structures for bill of quantities:
The work package breakdown structure undertakes measurement and description divided into employer, quantity surveyor or contractor defined work packages (based either on a specific-trade, or a single package comprising a number of different trades). This structure may be preferred by contractors for procuring from their supply chain.
