다국어 초록 (Multilingual Abstract)

The construction industry is plagued by a high proportion of industrial accidents and fatalities Approximately half of all industrial fatalities in 2024 will occur mainly in the specialized construction. This is due to the numerous subcontractors and complex work environments across various types of work, which often leave blind spots in risk management and a high probability of serious accidents. Construction sites primarily rely on risk assessments, primarily those based on frequency and intensity methods, which often hinder the precise identification of task-specific risk factors. This study aimed to propose an effective method for identifying hazards and risks appropriate for each task and type of work in the specialized construction industry. A survey was conducted with 83 workers from four specialized construction companies engaged in architectural reinforced concrete and infrastructure earthwork and reinforced concrete work. The survey analyzed the current status of risk factor identification methods, the necessity of applying them to each task, and the reasons for selecting them. The analysis revealed that the frequency and intensity risk assessment method is widely used in most construction sites. However, the need for alternative methods, such as work plans or pre-work permits, was raised for unit tasks: system scaffolding and shoring, CPB, insulation and curing, hot work, confined space work, and vehicle loading and unloading and construction equipment. A majority of respondents believed that applying differentiated verification methods for each unit task facilitates the identification of risk factors tailored to the specific task, enhances worker understanding and participation, and is effective in preventing accidents. This study emphasizes the need to develop a customized risk assessment system that reflects work characteristics of the specialized construction industry.
