BIM-FM integration through openBIM: Solutions for interoperability towards efficient operations

Facility Management (FM) faces ongoing challenges related to data interoperability and information loss during the transition from construction to operation phases, compromising asset management efficiency. Although Building Information Modeling (BIM) can optimize the flow of information exchange by offering a single, centralized model, the lack of standardization and interoperability issues between BIM and FM limit the full exploitation of its advantages. This study aims to develop a solution that integrates BIM and FM, using open standards like IFC to mitigate data loss and ensure continuous updates of BIM models throughout the construction and commissioning phases. The proposal aims to provide the facilities team with a BIM model containing the minimum necessary and reliable common information for the start of operations. The methodology adopted is based on Design Science Research (DSR) and includes the development of an artefact composed of four components: (1) a compendium of minimum common information requirements for various assets, (2) a web platform for continuous management of this information, (3) a Representational State Transfer API (Application Programming Interface) that ensures interoperability between different systems, and (4) an add-on for the Blender system, utilizing Bonsai (previously known as BlenderBIM) as the IFC modeler, which guarantees bidirectional data exchange between the web platform and BIM models, ensuring continuous verification and updating. The results show that the proposed artifacts are effective in mitigating interoperability difficulties, centralizing critical information, and continuously verifying data. The use of IFC promoted greater flexibility and standardization, resulting in more efficient and integrated asset management. The proposed solution offered a practical and sustainable approach for the construction industry, significantly contributing to the improvement of operational processes and information management throughout the asset lifecycle by decoupling from the limitations imposed by proprietary software.
