Effective communications among team members enable them to stay resilient and make rapid decisions when they are facing uncertainty and complexity during an incident with time and resource constraints. With the rapidly-expanding indoor positioning technologies that support public safety operations, a more efficient and effective building information platform is needed to support indoor location data visualization and coordination efforts. On the other hand, building information modeling (BIM) has been widely accepted in the Architecture, Engineering, and Construction (AEC) industry as a central repository of building information. BIM does not only include accurate geometric building data and sufficient semantic information but also could be integrated with real-time smart building data. The ultimate goal of this research effort is to bridge the technology gap between various emerging indoor positioning technologies and abundant building information and thus to overcome the main shortcoming of the existing indoor building model. A BIM-based Indoor Location (BIMIL) portal is designed in this work for automatic data extraction, visualization, and transformation of BIM emergency-related data for public safety purposes. Subsequently, the new generalized building 3D model can be overlaid with indoor positioning data to support emergency responses.
