Heritage restoration projects face numerous challenges, including the preservation of historical accuracy, effective stakeholder collaboration, and maintaining transparent records of interventions. This paper proposes a theoretical framework that integrates Building Information Modelling (BIM) with blockchain technology to overcome these challenges and preserve the authenticity and integrity of heritage restoration. The integration of BIM's digital modeling capabilities with blockchain's decentralized immutable ledger creates a transparent, traceable system for managing heritage restoration projects. The proposed framework enhances trust among stakeholders, streamlines regulatory approvals, and ensures the long-term preservation of both the digital and physical aspects of heritage assets. Although this integration holds significant potential, the study also highlights key challenges such as cost implications, and ethical considerations. Future work is needed to develop practical implementations, define standards, and address legal and policy gaps to facilitate the adoption of this innovative approach in heritage conservation.
