Elemental 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 elemental breakdown structure undertakes measurement and description by group elements, with each group element forming a separate section of the bill of quantities, irrespective of the order of work sections in NRM 2. Group elements are sub-divided through the use of elements, which are further sub-divided by sub-elements, as defined by NRM 1: Order of cost estimating and cost planning for capital building works.
