Quantitative Analysis of the Accident Prevention Costs in Korean Construction Projects

It is essential to objectively evaluate accident prevention costs (APCs) to respond to high-accident rates in the construction industry. However, currently, no quantitative APC analysis model considers the properties of the Korean construction industry. Therefore, in this study, the APC quantification structure was derived to comprehensively evaluate the properties of Korean construction projects, such as occupational safety and health management funds, safety management expenses, and others. Subsequently, the current status of APC in Korea was analyzed based on case studies on 38 projects for which questionnaires were collected. As a result of the study, the average ratio of the APC to total construction cost of the target project was calculated to be 1.95%. In addition, an average difference exists between groups according to client types and facility types in the target project. This study developed an APC quantification model considering Korea’s safety-related laws and insurance systems. It is expected that the results of this study can be used as objective data for evaluation according to the target project type.
