이 연구의 목적은 재해강도와 재해발생 가능성, 재해영향요인을 종합적으로 고려하여 건설현장의 특성을 반영한 위험성 평가방법을 개발하는 것이다. 이 연구에서는 액티비티를 중심으로 재해강도와 재해빈도의 정량적인 측정방법을 제시하였으며, 재해빈도와 기상조건, 작업자 특성 등 재해영향요인을 조합하여 확률적인 관점에서 재해발생 가능성을 측정할 수 있는 방법을 제시하였다. 사례연구를 통해 재해강도와 재해빈도 측정방법의 적정성을 확인하였으며, 재해영향요인은 건설현장의 작업환경과 조건을 고려한 실질적인 위험도를 산정하는데 기인하는 것으로 나타났다. |

Current risk assessment methods typically determine accident risks embedded in construction projects by combining severity and frequency; however, they do not reflect the characteristics of construction projects. To solve the problem, this study aims to develop a novel risk assessment method that combines severity, frequency, and disaster influence factors (i.e., weather conditions and worker’s characteristics) for assessing risks of activities occurring on a construction site actually. In this study, a severity was estimated by death against victims, and a frequency was estimated by the victim rate. The frequency was then converted to probability taking disaster influence factors into account. Thus, instead of considering severity and frequency for assessing the original risks (RO), the proposed method uses severity and probability to yield adjusted risks (RA) for each activity. A case study was conducted to determine if the proposed method works as intended in a real setting. The results show that RA is more sensitive to disaster influence factors than RO and, therefore, is able to assess the actual risks reflecting the working environment and conditions of a construction site. This study contributes to risk management of construction projects by offering a risk assessment method that measures a possibility of potential disasters from the probabilistic perspective. This method would help project managers assess accident risks in a more systematic and quantitative manner. |
