Abstract

A key use of applying building information modeling (BIM) to the construction stage of a project is to help identify construction obstacles and to visualize construction status according to the progress of the construction schedule. When employing 4D simulation for this purpose, start and finish dates for each activity and a 3D model of the activity must be prepared. In this work, in order to simplify the configuration of a 4D model, minimum attribute information of the BIM model produced in the design stage was used to construct a system that generated activity information in the construction stage using a clustering algorithm. Its usefulness as actual schedule management information was then analyzed.

건설공사의 시공과정에 BIM을 적용하는 목적은 시공 간섭의 파악과 함께 공사일정의 경과에 따른 시공현황의 시각화가 주요 이유이다. 4D시뮬레이션은 이러한 목적의 수행 기능이며, 이를 위해서는 공정별 시작 및 종료일자와 해당 공정의 3D모델이 갖추어져야 하고, 실무적 편리성을 확보하기 위해서는 이러한 기본정보의 활용이 간편한 기능 구성이 필요하다. 본 연구에서는 4D 모델 구성을 간소화하기 위해 설계단계에서 제작된 BIM 모델의 최소한의 속성정보를 활용하여 시공단계에 활용 가능한 공정 정보를 군집알고리즘을 이용해 생성하며 실제 공정관리 정보로서의 활용성을 분석한다.
