Abstract

One of the crucial components in building information modeling (BIM) is data. To systematically manage these data, various research studies have focused on the creation of object breakdown structures and property sets. Specifically, crucial data for managing programs and payments involves work breakdown structures (WBSs) and cost breakdown structures (CBSs), which are indispensable for mapping BIM objects. Achieving this requires disassembling CBS quantities based on 3D objects and WBS. However, this task is highly tedious owing to the large volume of CBS and divergent coding practices employed by different organizations. Manual processes, such as those based on Excel, become nearly impossible for such extensive tasks. In response to the challenge of computing quantities that are difficult to derive from BIM objects, this study presents methods for disassembling length-based quantities, incorporating significant portions of the bill of quantities (BOQs). The proposed approach recommends suitable CBS by leveraging the accumulated history of WBS-CBS mapping databases. Additionally, it establishes a unified CBS code, facilitating the effective operation of CBS databases.

BIM에서 가장 중요한 요소 중의 하나가 디지털 데이터이다. 체계적인 디지털 데이터 관리를 위해 최근까지 연구를 통해 객체분류체계(OBS)와 속성분류체계(Pset)가 제시되어 왔다. 특히 공정 및 기성 관리에 사용되는 디지털 데이터는 WBS와 CBS로 나뉘고 이를 BIM 객체와 매핑하려면 CBS의 수량 분개가 필요한데 CBS는 양이 매우 방대하고 공종이나 규격, 명칭 및 CBS 코드가 발주처마다 상이하여 WBS나 BIM 모델에 맞는 수량 분개 작업을 엑셀 등을 이용해서 수작업으로 한다는 것은 사실상 어렵다. 이러한 문제점을 극복하기 위해 BIM 모델에 의해 산출하기 힘든 수량 중에서 대부분을 차지하는 연장에 근거한 수량의 전체분을 분개하는 방안, 축적된 WBS-CBS 이력으로부터 최적 CBS를 도출하는 방안과 합리적인 CBS 데이터베이스 구축을 위해 필수적인 CBS 코드 통합 표준화 방안을 제시하였다.
