The Precast Concrete method (referred to as the PC method) is a method of manufacturing the concrete members in a factory and bringing them to the site to assemble them. The factory production of the members simplifies on-site construction and shortens the construction period. In addition, since members are manufactured in factories with good working conditions, it is advantageous in terms of quality control and safety management. Recently, PC method is expanding due to rising labor costs by the decrease in foreign workers and shorter working hours. As the construction market by the PC method is activated, the quality of PC members must be secured. However, there is a lack of engineers with professional knowledge in PC manufacturing factories and sites. And there is no system for quality assurance, which is the most important factor in PC manufacturing. In this study, domestic and foreign factory certification systems were investigated to propose a PC factory quality certification system that can ensure safety and quality of PC members from munufacturing to site delivery. In addition, a survey was conducted to PC-related workers to prepare data on the recognition of the introduction of the PC factory certification system and the factory certification method. Based on the survey results, basic data for the introduction of the factory certification system to revitalized PC apartment buildings were prepared.
