Deep renovation and construction projects generate heterogeneous datasets including BIM models, legacy CAD files, sensor logs, inspection records, and regulatory documentation. Current Digital Building Logbooks (DBLs) often remain fragmented across isolated systems, limiting interoperability, traceability, and trust. This paper presents BUILDCHAIN DBL, a decentralized digital logbook architecture that integrates semantic technologies and decentralized identity mechanisms. System’s architecture combines (i) an IFC-aligned ontology that semantically integrates heterogeneous building data into a machine-readable knowledge graph, (ii) a blockchain layer implementing W3C-compliant Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to ensure data provenance and tamper-evident auditability, and (iii) an application layer enabling credential management and lifecycle monitoring. The development methodology, system architecture, and workflow processes are described and validated through a real-world case study at the Hospital Real in Granada, Spain. Experimental results show that credential-based workflows execute within interactive latency thresholds ( 300 ms), demonstrating the feasibility of decentralized DBLs for construction and deep-renovation workflows.
