Developing a Support System for the Supervision of Construction Estimation

Abstract

Creating cost estimation sheets is one of business affairs in the field of construction. The cost estimation sheets are required to summarize necessary items, quantities, and prices for construction work in process. Since the contents of the cost estimation sheets directly affect the details of works, it must be always accurate without any errors. Therefore, the supervision process based on the past use cases is required to confirm the validity of the sheets in the final step. However, the past cost estimation sheets are stored separately from the other construction projects, so it is necessary to manually check them one by one to find the desired use case, which requires an enormous amount of time and effort. To solve this problem, we prepare a database from the past cost estimation sheets and develop an efficient system that can find the past use cases in the audit process.
