New rules of measurement

The RICS new rules of measurement (NRM) suite of documents provides a standard set of measurement rules that are understandable by anyone involved in a construction project. Although principally based on UK practice, the need for a coordinated set of rules and underlying philosophy behind NRM has worldwide application. The NRM suite comprises 3 volumes.

NRM 1: Order of cost estimating and cost planning for capital building works

The 1st edition, NRM: Order of cost estimating and elemental cost planning, published in February 2009, but several factors prompted a 2nd edition. The opportunity was also taken to simplify and augment certain aspects of the rules. The 2nd edition took effect from 1 January 2013.

NRM 2: Detailed measurement for building works

This first edition of NRM 2 took effect from 1 January 2013. It replaced the Standard Method of Measurement for Building Works (SMM), its latest version being SMM7.

NRM 3: Order of cost estimating and cost planning for building maintenance works

NRM 3 provides essential guidance on the quantification and description of maintenance works for the purpose of preparing initial order of cost estimates during the preparation stages of a building project, elemental cost plans during the design development stages (pre-construction) and detailed asset-specific cost plan (post-construction) and throughout the in use phases of a building project or facility.The guidance provided by the rules also aids the procurement and cost control of maintenance works. NRM 3 took effect from 1 January 2015.
