Work section 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 section breakdown structure undertakes measurement and description by the work sections listed in NRM 2. This structure may be preferred by contractors, as similar products and components are grouped together, rather than being spread across a number of different elements as they are in an elemental breakdown. This can make pricing easier for contractors.
