“…The research on the in-situ production of PC members [32][33][34] has mainly focused on the production area, with no study on the storage yard layout risk management. A review of the research on yards at construction sites showed that there has been no study on yards for the in-situ production of PC members [35][36][37][38][39], using manufacturing theory for the proper inventory management at construction sites. Therefore, the purpose of this study was to conduct a basic risk analysis of storage yard layout management for in-situ PC production.…”

A previous study confirmed that the in-situ production of steel-connected precast concrete (PC) members could reduce the cost by approximately 14.5-39.4% compared to factory production. Moreover, if PC members are produced in the field under equal conditions, the same or higher quality is secured compared to factory production. According to these studies, PC members should be produced on-site, because it is advantageous in terms of cost and quality. However, it is difficult to produce the necessary quantities onsite because of various constraints, including the allotted time. In particular, the storage area is significantly larger than the production area, and the availability of in-situ production is determined by the storage area. However, in the existing studies related to the in-situ production of PC members, no specific studies on storage yard layout management risk were conducted. The objective of this study was a basic risk analysis of yard stock arrangement management for in-situ PC production. In the future, depending on the frequently changing conditions at a construction site, the method developed in this study could be used to review the storage location.
