A STUDY ON THE ACTUAL PROCESS OF CREATING SHOP DRAWINGS IN THE RAMEN PRECAST CONCRETE CONSTRUCTION METHOD

This study clarifies the process of creating shop drawings in the Ramen Precast Concrete (RPC) method, focusing on information sharing and role distribution among designers, contractors, and PCa factories. Based on a questionnaire survey and interviews, cooperation between general contractors and PCa factories was analyzed. By patterning the drawing process, the study examined how information is exchanged. Deficiencies in design documents and delays in approval drawings negatively affect production, and BIM/ICT technologies are not widely used. Establishing a more efficient information exchange system and streamlining the shop drawing process are essential.
