Reliability centred maintenance
The New Rules of Measurement (NRM) are published by the Royal Institute of Chartered Surveyors (RICS). They provide a standard set of measurement rules for estimating, cost planning, procurement and whole-life costing for construction projects.
NRM3: Order of cost estimating and cost planning for building maintenance works, defines ‘Reliability centred maintenance’ (RCM) as:
This requires a mix of preventative maintenance, proactive maintenance and reactive maintenance designed to optimise reliability whilst minimising costs. It is based on the principle that using any one of these three types of maintenance alone would be somewhat arbitrary and unlikely to minimise failures.
There is a detailed description of different types of RCM at https://www.wbdg.org/resources/reliability-centered-maintenance-rcm
