Abstract

The automated quantity take off technique using BIM authoring tools has been recently issued, and the studies of this method for the accuracy, efficiency, and the unit computing for the simple volume, area and number have been developed. Meanwhile the main concerns such as the details for the level of modelling, and the costs and time for the calculating BOQ item are still required to study. In this paper, the earth works, drainage works, pavement works, and facility works using BIM authoring tools are designed in 3D, and the applicability of automated quantity take off technique using BIM authoring tools is discussed, respectively. As a result, automated quantity take off are limited in the earth works, drainage works, pavement works, and facility works. But Most items of BOQ can be supported in Re-bar model.

최근 BIM저작도구를 활용한 자동수량산출에 대한 관심이 많아지고 있으며, 단순한 부피, 개수, 면적 등의 단위계산 뿐만 아니라, BIM 기술을 이용한 물량산출의 정확성과 효율성에 대한 연구가 수행되고 있다. BIM 저작도구를 통한 자동수량산출은 매우 유용한 기능이나, 내역서 항목별 수량산출을 위해서는 모델링의 상세 수준을 높이는 등 많은 시간과 비용이 투입되어야 한다. 이에 본 연구에서는 2D 기반으로 설계된 도로건설공사 도면을 바탕으로 BIM 저작도구 이용하여 토공 및 도로공과 구조물을 3D 모델링 하고 BIM 저작도구에서 제공하는 자동물량산출기능을 통해 활용성을 살펴본다. 그 결과 토공 및 도로공이나 구조물공에 대하여 산출되는 자동수량산출의 항목들은 매우 제한적이나, 철근 모델은 수량산출서 항목의 대부분을 지원함을 알 수 있다.
