Blockchain-enabled digital twin collaboration platform for fit-out operations in modular integrated construction
Abstract Facilitated by the improved prefabrication rate and polymerization degree using Modular Integrated Construction (MiC), fit-out operations are converged with the off-site production and on-site assembly of prefabricated modules. Information technologies are used for MiC fit-out management and heterogeneous digital twins are generated. However, flexible collaboration of digital twins is hard to achieve and synchronized information sharing among transdisciplinary stakeholders is also hindered by “Islands of Information”. Therefore, this paper develops a blockchain-enabled digital twin collaboration platform for MiC fit-out operations. Firstly, Integrated Domain-Driven Design (IDDD) model is proposed for information integration and interoperation in cross-domain construction projects. Secondly, based on IDDD, digital twins in various domains are integrated for seamless and transparent collaboration in MiC fit-out. Thirdly, Petri net-based workflow model is applied for collaboration of multi-domain digital twins under versioning smart contract, where net structure and behavior attributes facilitate the automatic control during off-site and on-site MiC fit-out processes.
Highlights Integrated Domain-Driven Design (IDDD) model is proposed for information interoperation among trans-discipline stakeholders. Multi-domain digital twins are integrated for seamless and transparent collaboration under MiC fit-out blockchain. Petri net-based workflow model for real-time state monitoring and dynamic control in MiC fit-out projects.
