Abstract

Previous studies reveal the need for a tool to cost estimation of building design in early design stages. This paper proposes an internal finishes cost model tool to address this need. The tool allows users to evaluate the functionality, economics and quality of finishes concurrently with high-rise building design. Lack of information in the early stages of the project enables a relatively accurate estimates of work to raise up. Measurements are automatically extracted from simple design information and profile driven estimates are revised in real-time. The data model uses a flexible unit rate system that can easily be extended to other estimate dimensions such as mix-use building surcharge rate estimation. The approach illustrated in this paper is applicable to BIM tool conceptual estimation that support for massing purposes other than the one chosen for this study.

건설 프로젝트는 생산과정 이전에 설계도면을 바탕으로 예상되는 비용이 산정되며, 기획단계는 소요예산을 책정하고 설계단계는 예산에 합당한 효율적 대안을 찾으며, 정확한 입찰금액을 예측하기 위해 수차례 이루어진다. 특히, 물량산출 이전까지 예측되는 공사비의 정확도와 신뢰도는 매우 중요하다. 그러나 국내의 경우 면적당 단가 방식 공사비 예측을 벗어나지 못할 뿐 아니라, 단계별 예측방법, 프로세스, 데이터 분석 및 관리기술 등이 표준화되어 체계적이고 종합적으로 관리되지 못하고 있다. 그리고 복합용도 프로젝트에서의 견적은 그 사례도 적고 단가정보를 얻기가 매우 어렵다. 이에 국내 복합용도 프로젝트 공사비 예측기술 및 관리기술 발전을 위하여 BIM의 공간정보를 활용한 내부마감 개략견적 코스트 모델을 개발하여 제시하였다.
