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 ‘unplanned maintenance’ (or unscheduled or reactive maintenance) as:
‘…reactive and non-emergency work activities that occur in the current annual programme (i.e. maintenance carried out to no predetermined plan). Activities may range from unplanned/unscheduled maintenance of a nuisance nature requiring low levels of skill for correction, to non-emergency tasks involving a moderate to major repair or correction requiring skilled labour.’
