Abstract
Prefabricated building is the new construction method of technical reform and upgrading in China’s construction industry. The construction of prefabricated buildings involves the production, transportation and hoisting of large prefabricated components. Due to the difficulty in handling large prefabricated components, lacking of prefabricated building construction experience of workers, insufficient management guidelines for prefabricated building, there are a large number of hazard sources in the new production environment. This paper is to identify hazard sources relating to prefabricated components which exist in four stages of production, transportation, on-site storage, and installation. Firstly, we used the method of literature study to initially identify the hazard sources of prefabricated buildings; then, expert investigation was applied and Entropy Weight Method was used to evaluate the severity of hazard sources; finally, significant hazard sources at each stage were identified and countermeasures were put forward for the prevention of accidence. This study enriches the theoretical research on prefabricated building safety management and provides references for the prevention of prefabricated building safety risks.
