A BIM-Oriented Approach for Facilitating Indoor Navigation
Tragic disasters in cities (New York 9/11, London, Prague) have clearly revealed that the existing indoor navigation approaches such as navigation based on 2D geometries and pre-defined routing remain insufficient for a successful evacuation operation. Furthermore, delivery companies experience problems of getting oriented in large office buildings with facility managers spending extra time for locating utility failures inside buildings. The insufficiencies caused by existing navigation approaches can be overcome by using semantically rich intelligent building models for indoor navigation. The indoor navigation process requires the use of a number of interrelated models of buildings for the calculation of navigation paths, visualization of the navigation, and for assisting the actors in the process. Recent research indicated that primal and duals of geometric and topologic representations of buildings need to be constructed for fulfilling the indoor navigation modeling requirements. In this paper, we present a novel Building Information Model (BIM) Oriented approach for defining a building model for supporting indoor navigation, and later introduce a BIM Oriented Indoor Data Model (BO-IDM), which benefits from the best properties of IFC BIM and CityGML for supporting indoor navigation. The approach chosen in defining the model was BIM Oriented Modeling, which focuses on preserving the most semantic aspects of the BIM while adapting the GIS concepts in geometric representation of the building elements. This paper explains the BIM Oriented Modeling methodology used for the definition of this new model and describes the transfer of information from a standard BIM into the BO-IDM. The results of the research indicate that the BO-IDM carries the potential of facilitating emergency response operations by overcoming, i.) the limitations of geospatial and city models regarding representation of semantic information required for navigation and ii.) the non-geo-referenced structure and complex geometries of BIMs.
