RICS has recently published the second part of its New Rules of Measurement (NRM), following on from the publication of the first part in 2009 (since updated). The NRM seeks to provide a standard set of measurement rules designed to be comprehensible for quantity surveyors, property developers, contractors, professional consultants and construction lawyers.

It is intended that NRM will replace the Standard Method of Measurement, currently in its seventh edition (SMM7). Initially, RICS envisaged that the "switch over" would take place in summer 2010, but this has now been pushed back to July 2013.

All three versions of the 2011 JCT Standard Building Contract and both versions of the Intermediate Building Contract refer to SMM7 in their definition of "Standard Method of Measurement". Construction professionals/their lawyers should now start thinking about amending this definition.
