| Abstract |
Modular Construction is regarded as having enhanced safety compared to traditional construction since most of modular manufacturing
process in plants. Unlike general consideration for safety in modular construction, several industrial accident data and studies have pointed
out that the accident rate of modular construction is not enough less as much as the practitioners have expected. It means that there is a
clear need for improvement of safety management in modular construction. To enhance safety, it is necessary to identify the type and
cause of accident through accident cases in order to prevent safety accident in advance. In this consideration, this study analyzed the types
and causes of accidents through root cause analysis procedure with accident cases of U.S. OSHA. The classification was carried out in the
order of process type, accident type and cause of accident. By following the classification criteria in this study, the causal factor was
derived and the root cause map was created. Based on the analysis results, cross-analysis was conducted and it is shown that activity
characteristics of modular construction are related to safety accidents. In addition, prevention methods to reduce safety accident by major
activity are presented in terms of organizational, educational and technical aspects. This study contributes that the result can be used as the
basic safety management in the manufacturing and construction process of modular construction. |
