【Abstract】Traditionally, construction managers were considered more experienced in project management than offsite production management, although the latter is gaining importance with the renaissance of modular construction worldwide. Various Internet of Things (IoT)-enabled Building Information Modelling (BIM) platforms have been developed to facilitate production management by providing better information visibility, traceability, and a more collaborative working environment. Nevertheless, by and large, existing platforms suffer from two shortcomings: (a) the 'single point of failure' problem of IoT networks and (b) how to guarantee the provenance of BIM modifications from multi-sources. This research aims to develop a blockchain-enabled IoT-BIM platform (BIBP) for off-site production management in modular construction (OPM-MC) that can overcome the shortcomings. A design science research method is adopted to develop a three-layer BIBP system architecture. The system architecture is implemented and then compared with the existing IoT-enabled BIM platform. It was found that BIBP can avoid a single point of failure in IoT networks and ensure the provenance of BIM modifications with reduced storage costs in OPM-MC. The system architecture developed in our study can help the industry advance beyond the rhetoric to develop practical blockchain-enabled IoT-BIM applications. Future works are recommended to fine-tune the platform and test and evaluate it in various scenarios. (C) 2021 Elsevier B.V. All rights reserved.
