Abstract

Productivity estimation of construction operations is crucial to successful project delivery. Especially in the preconstruction phase, the adequacy and effectiveness of plans directly affect the actual performance of operations. Currently, productivity estimation is conducted by referring to existing references such as the Construction Standard Production Rate. However, it is difficult to promptly apply changing conditions of operations when using such references. Moreover, it is difficult to deduce the optimal combination of construction machinery for the given condition. This paper presents a simple simulation model that can be used to generate productivity data that considers site conditions and construction equipment combination. The suggested method is expected to be used as a decision making assisting tool for practitioners who rely on estimations using the Construction Standard Production Rate when establishing construction plans using heavy machinery such as backhoes, loaders and dumptrucks.

건설 프로젝트의 성공적인 수행을 위해 공정 생산성 예측이 필수적으로 요구된다. 특히, 시공 단계 이전에 수행되는 계획의 정확도 및 실효성은 시공 단계의 성과에 큰 영향을 미친다. 기존의 생산성 예측은 표준품셈과 같은 기존 문헌 참고를 통해 수행된다. 그러나 이러한 방법은 변화하는 조건을 즉각적으로 반영하는 것과 공사 수행에 필요한 최적의 장비 조합을 도출하는 것이 어렵다. 본 연구에서는 이산 이벤트 시뮬레이션 기술을 이용하여 장비 조합에 따른 생산성 데이터베이스 구축 방법을 제시하였다. 제시된 방법을 통해 표준품셈 기반 공정 계획 수립을 하는 관리자에게 굴삭기, 로더, 덤프트럭 등으로 수행되는 작업에 대한 최적 시공 계획 수립을 할 수 있을 것이라 예상된다.
