Persistent operation and management (O desktop BIM lacks context; tethered VR causes motion sickness and drift. This research presents a HoloLens 2 holographic-BIM framework that anchors centimetre-accurate as-built models to their physical twins and enables zero-controller, gesture-based interaction. By merging holographic visualization with spatial - semantic cues, the system heightens immersion and deepens cognitive understanding, improving O&M efficiency and quality.
