Facilities engineering

"Facilities engineering, as distinct from new construction, refers to the series of operations carried out after basic structures are  complete. It involves the services necessary to keep any large  physical plant functioning efficiently: maintenance and repair of  buildings, surfaced areas and grounds, service to refrigeration and  air conditioning, minor ancillary construction, fire prevention,  removal of trash and sewage, rodent and insect control, water purification, custodial services, management of property, engineer planning, supply of maintenance materials, and maintenance of  equipment used in the upkeep of a base."
