Abstract

Despite continuous safety management, the death rate of construction workers is not decreasing every year. Accordingly, various studies are in progress to prevent construction site accidents. In this paper, we developed an AI-based priority inspection target selection model that preferentially selects sites are expected to cause construction accidents among construction sites with construction costs of less than 5 billion won (KRW). In particular, Random Forest (90.48 % of accident prediction AUC-ROC) showed the best performance among applied AI algorithms (Classification analysis). The main factors causing construction accidents were construction costs, total number of construction days and the number of construction performance evaluations. In this study an ROI (return of investment) of about 917.7 % can be predicted over 8 years as a result of better efficiency of manual inspections human resource and a preemptive response to construction accidents.

지속적인 안전관리에도 불구하고 매년 건설업 근로자 사망율은 줄어들지 않는 추세다. 이에 따라 건설현장 사고를 예방하기 위한 다양한 연구가 진행 중이다. 본 논문에서는 건설공사 비용 50억원 미만의 건설현장 중 건설사고가 발생할 것으로 예상되는 현장을 우선적으로 선별하는 AI기반 우선점검대상 선정 모델을 개발하였다. 특히, 적용한 AI 알고리즘 중 분류분석에서 가장 뛰어난 성능(사고발생예측 AUC-ROC 90.48 %)을 보인 랜덤 포레스트를 모델 개발에 활용하였으며, 건설사고를 유발하는 주요한 요인으로는 공사비, 총공사일수, 공사실적평가액이 확인되었다. 본 연구를 통해 점검인력 효율화와 건설사고에 대한 선제적 대응의 결과로 8년간 약 917.7 % ROI(투자수익률)를 기대할 수 있다.
