Abstract

Many construction projects have extensively adopted building information modeling (BIM), and various institutions and standards have been developed domestically in Korea. However, the current process that is used to calculate building space area has a significant shortcoming in that there are two different laws to apply the method of measurement considering space boundaries for building element guidelines. For example, space area can be calculated by a polygon, which is modeling using a BIM-based computer aided design program, such that the space polygon is always exported as an inner-edge type. In this paper, we developed an automated algorithm to convert coordinates of space representation using industry foundation classes based BIM data. The proposed algorithm will enable engineers responsible for space management to use a BIM-based model directly in the space programming process without having to do additional work. The proposed process can help ensure that space area is more accurately and reliably.

국내외 건설사업에 BIM적용이 활발하게 진행되고 있으며, 이에 따라 국가적 차원에서의 제도 및 기준이 개발되어 BIM기반 건설사업에 적용되고 있다. 하지만, 국내에서 건물에 포함된 공간객체에 대한 면적을 산출하기 위한 기준은 주택법과 건축법으로 이원화 되어 적용되고 있으며, BIM기반 소프트웨어에서 생성된 IFC파일은 적용되는 기준과 상관없이 항상 동일한 공간객체의 형상정보가 생성되고 있는 실정이다. 이에 본 연구에서는 IFC기반 공간객체 및 경계객체의 속성정보를 활용하여, 적정한 면적산정 기준을 산정하고 이에 따라 해당 공간객체 형상정보의 좌표 값을 자동으로 변환시켜 줄 수 있는 IFC기반 공간형상정보 좌표 변환 자동화 알고리즘을 제안하고자 한다.
