Abstract: CCMAS is an integrated construction cost generator which may be used to develop costs for construction projects; to analyze and estimate facilities associated with major weapons programs; for administrative, medical and support facilities as well as runway/taxiways; and for developing the life cycle costs for various construction projects. Its uses parametric estimating techniques with a finite field of both codified and unstructured data elements in a unique process which may be accomplished with or without detailed plans or specifications. The system contains more than 900 types of Air Force facilities as well as the quantities of each product required to complete each building type. Estimating tools used include direct costs, life cycle costs and modifiers. Direct costs are further broken down into generic models, a comparative system, and a quantity takeoff (QTO) system. CCMAS has been found to be three times more accurate than conventional architectural and engineering costing techniques.
