Abstract:

The experience held by a cost estimating engineer is a valuable asset in every construction company. For a reliable cost estimation at the conceptual stage of a building project, the missing data and information, otherwise needed for a detailed cost estimate, have to be substituted by the knowledge of an experienced cost-engineer. Typically, a senior member of the contractor's organization is involved in the conceptual cost estimating process. The decisions are based on that individual's experience. His experience may constrain, or even bias, the selection of cost objectives. This can lead to an estimate that is not optimal. This paper describes the development of a prototype knowledge based system, aimed to assist the cost estimator in the conceptual cost estimate. The system was developed by systematically capturing the expertise of multiple experts at three construction firms.
