Systematic Review of Organizing The Data Flow of Systems Using Building Information Modeling and Distributed Ledger Technology

As the digitalization in the architecture, engineering, and construction (AEC) industry has been rapidly progressing, building end users will require more coverage of quality data for their built environment. Despite its obvious need, it is seldom for the building information modeling (BIM) to be distributed for such broad use cases thus far. A potential reason for the situation is the lack of the public repository that can provide the adequate access control for various users. Distributed Ledger Technology (DLT), including blockchain, is one of the promising resolutions for the problem. Numbers of preceding proposals for DLT-based BIM repository systems (BIM-DLT system) have proved the utility to date. Understanding the statistical facts of their configurations will become a significant assistance to determine the plausible data distribution system, and thus, to strengthen the project information life cycle. This article aims to build a representative framework through the integrated literature review (ILR). The review results showed that the system’s data flow was classified into two patterns. The judgment criteria for selecting the pattern of the system are expected to depend on the purpose of system implementation, and the purpose of automation through smart contracts is more important than the oracle problem.
