¿ä¾à2 In previous studies, it was confirmed that through the in-situ production of precast concrete members,costs could be reduced by 14.5-39.4% compared to in-plant production. In particular, it was confirmedthat the factory owner did not make a contract if it did not earn more than 20% of the production cost. If precast concrete members are produced in-situ under the same conditions, the quality equivalent tothat of factory production can be secured. As it is advantageous in terms of cost and quality, precastconcrete members must be produced in-situ. However, it is difficult to produce all quantities in-situdue to time and various other constraints. This is because in-situ production is avoided due toanticipated risks during the project management process. However, if the risk factors are analyzedbefore performing in-situ production of precast concrete members, it will increase the opportunity forin-situ production. Therefore, this study develops a checklist for evaluating the risk of in-situproduction of precast concrete members. By applying the checklist to one case site, it was verified thatrisk factors can be evaluated easily and quickly. As a result, it was analyzed that sites with a highbuilding coverage ratio are classified as high-risk sites because it is difficult to secure usable area forproduction and storage. The developed checklist efficiently evaluates the risk factors of in-siteproduction, and makes it possible for the operator to determine the risk factors, which can changefrequently during project execution, and respond according to the situation.
