Abstract
The integration of Building Information Modeling (BIM) into Facility Management (FM) remains challenging due to various project constellations and knowledge gaps that make it impossible for FM to set their information requirements (IR) for operation. To address this issue, this research develops a basic Information Delivery Manual (IDM) with an Information Delivery Specification (IDS) for Facility Service (FS) handover. The development process follows an iterative, expert-driven approach to refine the handover process, IR structure, and information definition. A core set of basic information was identified, representing the smallest common denominator of information essential for FS, while allowing for flexible extensions to accommodate building- or operator-specific requirements. The next phase involves practical testing in real-world FM environments to further assess its usability and impact. The results contribute to ongoing standardization efforts.
