Abstract

Unsafe working environments slow down working speed in that it takes a lot of time to respond in case of an accident, greatly reducing the productivity of construction work. Therefore, proper safety management that does not impede the productivity of construction works is a very important factor for successful construction project. However especially in mega project, the mutual effects of safety management and productivity are complex. Therefore, this study establishes a causal model between safety management and productivity influencing factors based on effectiveness metrics, and analyzes the effect of increased site congestion due to excessive personnel input, irregular safety measures and inefficient change of work schedules. The result of this study, is expected to contribute to enhancing the competitiveness of the construction industry as the basis for establishing a safety management plan that can secure appropriate productivity.

안전하지 못한 환경은 작업속도를 지연시키고, 사고 발생 시 대응에 많은 시간을 소요하게 하여 건설공사의 생산성을 크게 저하시킨다. 반면, 지나친 안전관리를 오히려 생산성 저해 요인으로 지적하는 연구도 존재한다. 따라서 건설공사의 생산성을 저해하지 않는 적절한 안전관리는 성공적 공사 수행에 매우 중요한 요인이나, 안전관리와 생산성 상호 간 미치는 영향이 복잡하기에 이에 대한 연구가 부족한 실정이다. 이에 본 연구는 시스템 다이내믹스를 활용하여 안전 관리와 생산성 영향 요인 간의 인과 모델을 구축하고, 효율성 지표를 통한 생산성 측정 및 분석을 진행한다. 이를 통해 과다 인원 투입으로 인한 현장 혼잡도 증가, 비정기적 안전 조치 및 비효율적 초과근무가 실제 작업에 투입되는 시간에 미치는 영향을 분석한다. 안전관리와 생산성의 상호 영향성에 대한 기초 연구인 본 연구의 결과물은, 적정 생산성 확보 가능한 안전관리 방안 수립의 기반으로서 건설산업 경쟁력 제고에 기여할 수 있을 것으로 기대한다.
