초록

건설공사 프로젝트에서 인력 및 장비 등의 투입자원 증가는 공정간의 작업공간 간섭을 유발할 뿐만 아니라 프로젝트의 생산성과 품질에 영향을 미칠 수 있다. 이를 해결하기 위해 작업공간관련 연구가 수행되고 있으나, 단순히 공정들의 기하학적 위치만을 고려하여 작업공간을 검증하거나, 작업공간의 형상을 세부 작업별 분리된 형상이 아닌 일괄적 하나의 객체 형태로 생성하고 있다. 이러한 방식은 공정의 특성과 자원의 투입 시간에 따라 변화하는 작업공간의 크기를 반영하지 못하므로 합리적인 작업공간 충돌의 분석이 어렵게 된다. 이를 위해 본 연구에서는 공정과 자원의 특성에 적합한 작업공간의 형상과 크기를 생성할 수 있도록 작업공간의 3차원 모델 생성방법과 운용 시스템을 개발한다. 또한 이를 적용한 작업공간 간섭최적화 연계방안과 건설장비의 최적 이동경로 탐색 방법론을 개발하여 실무적 활용성을 검증한다.

The increase of input resources, such as labor and equipment, in a construction project causes workspace interference between activities and it influences on the productivity and quality of construction activities. To solve this problem, many studies related to the workspace interference have been performed, however they verified the workspace concerning with only the geometric location of activities or generated the shape of workspace by a whole object concept not separated units of detailed operations. It is difficult for project manager to reasonably analyze the workspace conflict, because the size of workspace cannot reflect the characteristics of an activity and input time of a resource. This paper presents a methodology that can generate three-dimensional models in order to optimize the workspace shape and size by considering with the characteristics of each activity and input time of each resource. The suggested method can be used for the active BIM system that optimizes the workspace conflict without additional construction duration and for the searching algorithm of optimized moving path for construction equipment.
