Abstract This study investigates supply chain management (SCM) strategies for precast concrete (PC) projects using offsite construction (OSC). Five domestic OSC-PC cases were analyzed using site observations and expert interviews. Based on the findings, the project process was classified into three key stages: production, inventory-transportation, and assembly. For each stage, critical management factors were identified. In the production stage, emphasis was placed on maintaining consistent quality and timely production through effective product and mold management. The inventory-transportation stage focused on optimal inventory control and timely material delivery. The assembly stage highlighted the importance of resource allocation and process coordination for efficient on-site installation. Additionally, the Analytic Hierarchy Process (AHP) was used to prioritize key management factors. The findings provide practical insights for developing future OSC platforms and improving the operational efficiency of OSC-PC projects.
