NRM provides a standard set of measurement rules and essential guidance for the cost management of construction projects and maintenance works.

NRM consists of three volumes:

NRM 1 provides guidance on the quantification of building works for the purpose of preparing cost estimates and cost plans. It is the ‘cornerstone’ of good cost management of construction projects – enabling more effective and accurate cost advice to be given to clients and other project team members, as well as facilitating better cost control.

NRM 2 is written mainly for the preparation of bills of quantities and quantified schedules of works, although the rules will be invaluable for designing and developing standard or bespoke schedules of rates.

NRM 3 gives guidance on the quantification and description of maintenance works for the purpose of preparing initial order of cost estimates. The rules also aid the procurement and cost control of maintenance works.
