Abstract

For a holistic and precise assessment of safety benchmarks within a construction venture, it's paramount to delineate between the intrinsic features of the construction and its real-time, on-site performance metrics. In this study, we delved into genuine accident instances to discern the interplay between these construction attributes and on-ground performance determinants in relation to safety mishaps, employing the binomial logit analytical framework. Our scrutiny underscored that construction expenditure profoundly modulates the likelihood of fatal occurrences. Notably, variables pertinent to on-site safety protocols wielded considerable influence over both fatal mishaps and accidents implicating multiple personnel. These revelations intimate that while ascertaining the safety quotient of a construction initiative, a mere classification and recalibration based on fiscal dimensions can elucidate much. Yet, a comprehensive safety appraisal necessitates transcending quantitative indices, such as frequency of mishaps or casualty rates, to encapsulate the multifaceted interventions and strategies adopted at the construction locale.

건축 프로젝트의 안전 성과를 효과적으로 평가하기 위해서는 당해 사업의 공사특성과 현장 실행을 분리하여 검토할 필요가 있다. 본 연구는 실제 사고사례 데이터를 활용하여 건축공사 안전사고에 유의미한 영향을 미치는 공사특성 요인과 현장 실행 요인을 분석하였다. 안전사고의 유형을 사망사고와 다인 부상사고로 설정하고, 독립변수로 공사특성 변수, 현장 실행 변수, 외부환경 변수를 투입하여 이항로짓 모형을 구축하여 유의미한 변수와 그 영향력을 파악하였다. 분석 결과, 사망사고 발생 확률에 영향을 미치는 공사특성 요인은 공사비가 절대적이었다. 반면, 사망사고 및 다인 부상사고에서 현장의 안전 실행 변수들이 영향력이 컸다. 이는 건설 프로젝트의 안전 성과를 측정할 때 공사비에 따라 프로젝트를 분류하고 보정하는 것만으로도 충분한 설명력을 가지며, 사업의 안전 성과를 평가할 때는 현장의 다양한 노력과 조치를 성과지표에 반영하기 위한 노력을 필요하다는 점을 시사한다.
