To analyze the level of risk that comprehensively reflects the accident risk factors, the risk level of each construction work type was analyzed based on the construction accident case data, focusing on the work process and the accident object. Data was collected through web crawling, and risks were analyzed based on detailed work types, work processes, and accident objects. A frequency analysis by work type was performed to derive hazardous work types (reinforced concrete work, temporary work, dismantling and demolition work), and the risk level was analyzed considering the accident object and work process at the same time. The risk assessment results were visualized through a heat map. The results of this study can be used as basis data to establish more realistic safety management plans based on accident cases.
