Are standard methods of measurement unique to the UK?

No, many countries have their own standard method of measurement, some based on NRM2. 


Can the rules of measurement be altered?

Yes, provided that any departure from NRM2 is clearly stated in the contract bills in order that tendering contractors may take this into account.


Is it a contractual requirement that bills of quantities are prepared in accordance with NRM2?

No but, some contracts, for example JCT (2016) Clause 2.13.1, states that unless otherwise indicated the contract bills are to have been prepared in accordance with the NRM2.


What are operational bills of quantities?

This approach was developed during the 1960s and was based on breaking the project into operations. It was never adopted as the resultant bills of quantities were so large and the format so unfamiliar there was little incentive to adopt this approach.


What percentage of contracts is based on lump sum bills of quantities?

The latest statistics from the RICS indicate that recently the number has increased slightly to around 30%.
