Owner requirements in as-built BIM deliverables and a system architecture for FM-specific BIM representation

Construction models received by owners typically include the details of components required for construction activities; yet at the same time, they might not be in the right geometric representation for facilities management (FM) tasks. There is a need to customize BIMs for each FM task and eliminate unnecessary data in models for that task. The objective of this work is to identify information items that should be included in BIMs to support specific FM tasks and the level of geometric details of components to be represented in BIMs. The research focuses on supporting four major FM tasks as corrective and preventive maintenance management, asset management on HVAC systems, and space management tasks. This paper also provides a system architecture to enable reducing content of BIMs for FM tasks. Contributions will help practitioners to use facility data from a life cycle perspective through BIM.
