Security-aware data management in building information modeling processes using blockchain

Abstract

Building Information Modelling (BIM) is drastically transforming the way buildings and infrastructure is planned, built and operated. BIM envisions a collaborative approach that relies on a common data environment (CDE) for the exchange of data and models among all entities involved in project delivery. This paradigm promises increased efficiencies and streamlined coordination, but at the same time raises complex challenges concerning data management and data security. Despite strong interest in employing blockchain technology in BIM data management, a practical end-to-end architecture for its integration and implementation remain missing in the literature. This chapter presents the findings of an investigation of the major risks associated with BIM processes and summarises how they can be potentially be addressed by using the blockchain technology. Furthermore, it introduces a novel blockchain-based decentralised BIM network architecture to apply fine-grained monitoring and control on BIM information exchange in the CDE. Finally, the remaining challenges and prospects are discussed.
