by Keyu Chen, Zushun Li, Beiyu You, Xingyu Tao Building Information Modelling (BIM) project operation and maintenance information management in smart cities currently faces challenges like data redundancy, a large number of management and maintenance personnel, and complex processes. Blockchain technology, with its decentralized and non-tamperable characteristics, offers a potential solution to these challenges.
However, its direct application is not a panacea, as its complex deployment and cumbersome approval processes can introduce new challenges. Therefore, this paper proposes a lightweight blockchain-based BIM project O&M information management framework.
A Design Science Research (DSR) methodology was used to construct this framework, aiming to optimize the information management process and ensure its efficient application. First, a one-to-many mapping tool was developed to allow a single blockchain node to register multiple users, thus simplifying the deployment process and enabling a lightweight blockchain.
An InterPlanetary File System (IPFS)-based tool was also built for generating digital fingerprints to enhance data security and traceability.
