This title describes an investigation of the role of inspection in maintenance of building services. The work was done by interviewing two maintenance contractors, five building operators and and a specialist inspection organisation, together with a postal survey of 50 maintenance contractors. It describes inspection as "the process of determining if and what maintenance is required" and examines why inspection is undertaken, by whom and how. The book concludes that there is minimal evidence that formal inspection is acknowledged as necessary by either building operators or those offering a maintenance contract service. It also discusses inspection as understood by maintenance contractors and building owners, together with inspection frequencies, instrumentation and documentation.
