The scope of O&M includes the activities, processes, and workflows required to keep the entire built environment as contained in the organization’s Real Property Inventory of facilities and their supporting infrastructure, including utility systems, parking lots, roads, drainage structures and grounds in a condition to be used to meet their intended function during their life cycle. These activities include both planned preventive and predictive maintenance and corrective maintenance.
Facilities operations and maintenance encompasses a broad spectrum of services, competencies, processes, and tools required to assure the built environment will perform the functions for which a facility was designed and constructed. Operations and maintenance typically includes the day-to-day activities necessary for the building/built structure, its systems and equipment, and occupants/users to perform their intended function. Operations and maintenance are combined into the common term O&M because a facility cannot operate at peak efficiency without being maintained; therefore the two are discussed as one.
