The UK's Building Services Research and Information Association has carried out a number of condition-based maintenance review projects, which have identified the potential methods or approaches, appropriate plant items and benefits from such techniques in a building-services environment. This article examines the different condition-based maintenance techniques which can be incorporated into conventional building-services maintenance regimes. The building-services plant items which can potentially benefit from condition-based maintenance are highlighted, along with a number of the potential faults which are detectable. Also highlighted are some of the main difficulties encountered in establishing condition-based maintenance in building-services maintenance regimes, such as maintenance personnel's reservations about the implications on their current maintenance regimes, and the difficulties in justifying the costs associated with condition-based maintenance.
