The paper proposes a BIM-based maintenance workflow integrating augmented reality, panoramic image tagging, visual programming, and data streaming platforms for facility management. The methodology combines 360° spherical photography, BIM models, Dynamo scripting, Python automation, Speckle streaming, Grasshopper, and Fologram AR interfaces to create a real-time feedback system for building maintenance. Users can report anomalies directly within panoramic virtual tours, while maintenance operators interact with the BIM model through augmented reality interfaces connected to the building database. The workflow enables automated synchronization between physical spaces and digital twins, facilitating damage detection, metadata updating, and collaborative maintenance operations through accessible mobile and AR devices.
