BIMCHAINED: A BLOCKCHAIN SUPPORTED DIGITAL FRAMEWORK FOR REAL TIME CONSTRUCTION SITE MONITORING

Abstract: The construction industry uses BIM and Common Data Environments (CDE) for coordination, nevertheless struggles with data integrity, auditability, and trusted verification for safety compliance amid fragmented processes and BIM-blockchain oracle issues. This study proposes a hybrid framework integrating BIM, DynamoPython automation for parameter extraction and data validation, cryptographic hashing, and QR-codes linking physical assets to blockchain-ready records. In a Rome heritage refurbishment case study on mobile scaffolding, it produced verifiable inspection registers with compliance status and traceable hashes. The key contribution is a scalable prototype enhancing BIM safety monitoring traceability, enabling blockchain anchoring and openBIM-aligned digital twin provenance.
