Life‐Cycle Maintenance Costs by Facility Use

The U.S. Army Construction Engineering Research Laboratory, Champaign, Ill., has developed several data bases for determining life‐cycle costs of building facilities by functional use. Four data bases have been implemented in a DOS environment for an embellished personal computer. The simplest data base contains average annual maintenance per square foot by building use. The second data base contains both yearly component replacement and annual reoccurring maintenance cost per square foot by building use. The third data base contains labor hours per square foot, equipment hours per square foot, and material cost per square foot by building age and building use. The most detailed data base contains labor hours per square foot, equipment hours per square foot, and material costs per square foot for each individual maintenance task. All data bases can be applied by any organization (cities, universities, corporations) for resource prediction. The data bases are currently being applied by several Army organizations, the Department of the Interior‐Historical Preservation Council, Department of the Navy, ASTM (American Society for Testing Materials), and many private organizations. Contents and application of the data bases are described in this paper.
