Exploring the benefits of open BIM standards for enhanced interoperability and efficiency in architecture, engineering, and construction projects

This article presents an analysis of the impact of openBIM standards on interoperability and efficiency in construction projects. The hypothesis put forward is that the coordinated use of openBIM standards and services, such as IFC, BCF, bSDD, IDS, IDM, and UCM, improves the quality of information and reduces the number of errors during interdisciplinary coordination. For this study, ‘efficiency’ is defined as a composite of: (1) data quality, (2) coordination efficiency, and (3) time/cost (person-hours and related costs). The methodology combines a literature review with a practical case study of a conceptual BIM model of a museum building. The results indicate that each standard plays a distinct role: IFC enables uniform model transfer, BCF facilitates issue tracking, bSDD provides standardised semantics, IDS allows automatic data verification, IDM clarifies the flow of information between process participants, and UCM enables capturing and reusing best practices. Together, these standards improve data exchange, enhance coordination, and reduce errors. Challenges include limited tool support and the need for user training. In conclusion, openBIM standards support collaboration and efficiency; there is also a need for further research on their practical implementation.
