## 8 Conclusions  
The study aims to investigate the impact of BIM on the supply chain resilience of prefabricated buildings and construct a comprehensive conceptual framework to link BIM and supply chain resilience. It defines prefabricated building supply chain resilience and synthesizes previous critical studies on the factors influencing prefabricated building supply chain resilience. It further emphasizes the key role of BIM in facilitating supply chain management. The integrated review summarizes 25 important factors influencing the supply chain resilience of prefabricated buildings at the external, partnership, participant, and supply chain levels. Then, 21 key factors affecting resilience were further identified. Secondly, this study selects the evaluation indicators of BIM maturity and categorizes them into two dimensions: BIM resources and capabilities. Finally, it is proposed that BIM technology, reflected through resources and capabilities, enhances the supply chain resilience of prefabricated buildings by influencing the design capability, assembly capability, and construction capability at the participant level and the cooperation, information sharing, coordination, and trust at the partnership level. This study provides important theoretical contributions in understanding how digital tools enhance resilience. It unpacks the underlying mechanisms between BIM application and supply chain resilience in the context of prefabricated buildings. A conceptual framework linking BIM and supply chain resilience is established. Few studies have examined the role of BIM from the standpoint of supply chain management in prefabricated buildings, even though BIM is widely utilized in the architectural, engineering, construction, and operation sectors. The conceptual framework proposed emphasizes that BIM as a technology and management tool improves supply chain resilience and identifies six key mediators, including design capability, assembly and construction capability, cooperation, information sharing, coordination, and trust. The framework hence suggests more precise directions for future research. This study provides guidance to practitioners and project managers engaged in prefabricated buildings by highlighting the roles of BIM resources and capabilities. They can optimize their supply chain management strategies by focusing on key aspects of design, assembly construction, collaboration, information sharing, coordination, and trust through BIM use. This can help them better adapt to supply chain uncertainty, reduce risk, and improve management efficiency. It is also important for them to distinguish between BIM resources and capabilities. Resources are the foundation of BIM capabilities, and they can play indirect but indispensable roles in influencing supply chain resilience. The conceptual framework can inspire managers to provide resources such as training, software, and hardware for BIM use, as well as data and information to strengthen the competence of their staff in the utilization of BIM tools and techniques. Managers in construction organizations can optimize BIM capabilities by developing BIM work objectives, implementing standard BIM processes, mastering and innovating BIM technologies, building effective implementation teams, setting up effective monitoring mechanisms, and selecting partners with BIM experience and capabilities. There are still a few limitations. First, this study only examined the impact of BIM on supply chain resilience. Future research could extend to other related digital technologies and examine their possible effects on supply chain resilience. For example, the role of radio frequency identification (RFID) technology for tracking components in the prefabricated building supply chain can be further explored. Second, this study mainly conducts an integrated review. Future research could rely on a broader review to identify more elements that may impact supply chain resilience. The conceptual framework in this study can be further validated with more empirical cases.
