Abstract

As high-rise and irregularly shaped building structures have become a trend at home and abroad, BIM technology is now being developed and accepted widely. However, the BIM data and information generated in the design phase cannot be actively reutilized in the construction stage. This is because the major interests of construction companies include working process and cost estimation, while there is not usually enough BIM data created to support these activities. In order to resolve this issue, we need to set up BIM modeling guides that make it possible to extract correct quantity take-off from BIM data. Quality checks are also necessary to ensure that the resulting BIM data is correct. This study suggests ways of securing BIM quality for correct quantity take-off, which is critical for BIM technology applied to the building construction process and its cost estimation.

최근 국내외에서 건축물의 고층화 및 비정형화 추세 속에서 BIM기술이 활발히 이루어지고 있으나 설계단계의 BIM 데이터가 시공현장에 적극적으로 재활용되지는 못하고 있다. 건설 회사들의 주요 관심사는 공정 및 공사비 관리 등 여러 분야인데 BIM기술이 활발히 사용되기 위해서는 BIM 데이터가 이러한 용도로 활용될 수 있도록 올바르게 작성되어야 한다. 이를 위해서는 특히 BIM데이터를 건물 부재별로 수량을 올바르게 산출할 수 있도록 기준을 설정하여 BIM데이터를 작성하는 것이 필요하며 작성된 BIM데이터가 올바르게 만들어졌는지를 품질관리 차원에서 확인하는 것이 필요하다. 본 연구는 BIM기술이 건설현정의 공정 및 공사비 관리에 활용에 매우 중요한 물량산출을 올바르게 할 수 있도록 BIM데이터의 품질을 확보할 방안에 대한 제시를 목적으로 수행되었다.
