A blockchain-based solution for high-rise building maintenance and insurance claims using building information modelling (BIM) data

Purpose This paper proposes a blockchain-based solution for high-rise building maintenance and insurance claims, leveraging building information modeling (BIM) data to address limitations of centralized systems, including data integrity, accountability, traceability and reliability in insurance claims processing. Design/methodology/approach A private Ethereum blockchain was integrated with BIM, leveraging smart contracts for maintenance and insurance workflows. The system utilizes the InterPlanetary File System (IPFS) for decentralized storage of large datasets. Key innovations include smart contracts for stakeholder registration, building data management, maintenance agreements, insurance claim processing and reputation management. Findings The proposed system provides decentralized, transparent and traceable management of high-rise building data. By automating workflows through smart contracts, the system enhances data integrity and reduces redundancy in insurance claims. Testing confirmed the smart contracts’ reliability, functionality and capability to streamline operations. Research limitations/implications The system was tested in a simulated environment. Future research could explore scalability, adapting to regulatory frameworks and integrating advanced analytics to address complex maintenance scenarios. Practical implications The system improves accountability in maintenance tasks and simplifies insurance claims by creating immutable, tamper-proof records. Stakeholders can rely on transparent and secure data. Social implications Improved maintenance accountability and transparency in insurance claims enhance the safety and reliability of high-rise buildings, benefiting society at large. Originality/value This study introduces a blockchain-based solution tailored to the unique challenges of high-rise building maintenance and insurance claims, using BIM data to enhance transparency. A novel reputation mechanism is implemented to promote stakeholder accountability, advancing the application of blockchain technology in this context.
