Abstract

While a detailed cost estimation utilizes the comprehensive quantity information obtained from a complete drawing and specification, an approximate cost estimation heavily relies on the subjective decisions. This phenomenon is because the approximate estimation is usually conducted in early stage of the construction phase where the drawing and specification are not available. This study developed a roadway construction cost estimation system which enables users to estimate the approximated cost of the project in early stage. The system identifies the variation of the construction costs due to the road route change using a cased based reasoning(CBR) method. Overall the system is expected to improves the accuracy and effectiveness of the estimation process, because it would provide users with increased accessability and consistent results in early stage of the project which leaded to the increased work transparency.

완성된 도면과 시방서를 기초로 산출한 상세한 물량 정보를 토대로 상세 공사비를 예측하는 업무에 비해 도면과 시방서가 완성되기 이전 단계에서 시설제원이나 개략적인 설계 정보 등을 기초로 개략공사비를 예측하는 업무는 공사비 예측 업무 담당자의 주관적인 판단에 의존하는 경향이 크고 객관성이 낮은 실정이다. 본 연구에서는 도로건설공사 초기단계에서의 사업비 예측 모델을 연구하고 이를 토대로 건설공사 개략공사비 예측 시스템을 개발하였다. 이 시스템은 BIM 및 GIS를 이용하여 사업 초기단계 개략적인 노선선정에 따른 개략공사비 추정에 있어 사례기반추론을 기반으로 사업비 예측의 정확성 향상과 업무 선진화에 기여할 것으로 기대된다. 또한 사용자가 인터넷을 통해 편리하게 접근할 수 있고 객관적이면서 일관성 있는 개략공사비 예측 결과를 제공받을 수 있으므로 업무 투명성 측면의 효과도 기대할 수 있을 것이다.
