ABSTRACT
Building Information Modeling (BIM) is becoming a repository of building related data. To represent the building’s real-time information, a dynamic BIM for recording and storing timely and accurate sensory data of building’s components, spaces and occupants is required. Such a dynamic BIM can improve the building emergency management and enhance effective survival services in emergency conditions. This study aims to link sensory data to BIM, using the Industry Foundation Classes (IFC) standard, to capture, record and update the state of building elements, spaces and occupants. The objectives of this paper are: (1) extending IfcSensor entity to include occupant’s sensors; (2) defining the relationships between sensors, occupants, time series, and spaces; and (3) creating dynamic BIM for tracking occupants and environmental states. A case study to highlight the feasibility of the proposed model is presented.
