A bill of quantities in the UK is a schedule that defines the quantity and specification of the component parts of any given construction project.
It is generally produced to a recognised industry standard method of measurement dependent upon the sector of the project. The standard industry methods of measurement are SMM7 and NRM2 for construction, CESMM4 for civil engineering, MMHW for highways and RMM2 for rail.
The document is produced using drawings and specifications provided by the design team on the project. The process takes some time to complete and is carried out by skilled quantity surveyors trained in the technique of analysing the information to translate the design information provided into the relevant standard.
