Comprehensive facility management databases designed by the Facility Management Institute of Ann Arbor (Michigan) have three major sections or "files": the space inventory file, the property control file, and the building and grounds file. The first two are alpha-numeric in design, while the third is essentially a graphic file. The space inventory file is far more extensive than most current inventories and provides detailed information ranging from room characteristics through information on the occupants and their use of the space. The property control file is essentially outside the purview of normal space management, since it deals only with property control. The building and grounds file has, as its most significant element, a computerized record of both maps and site plans as well as building plans. This computerized approach permits the actual design of renovations on the computer. The savings appear to justify the costs of the system by permitting: (1) more appropriate space assignments, (2) reduced space redundancy, (3) improved space forecasting, (4) identification of sloppy management practices, (5) better bidding on renovation projects, and (6) improved maintenance and custodial care controls.
