A BIM-Oriented Model for supporting indoor navigation requirements

Existing indoor navigation approaches such as navigation based on 2D geometries and pre-defined routing remain insufficient for many applications such as emergency response, delivery, utility maintenance, facility management and so on. The insufficiencies caused by existing navigation approaches can be overcome by using the advanced geometric and semantic information included in intelligent building models.. In this paper, we present a novel Building Information Model (BIM) Oriented a model in order to support indoor navigation and orientation. This paper explains the BIM Oriented Modeling methodology used for the definition of a new indoor information model (BO-IDM) and describes the transfer of information from a standard BIM (IFC) into the BO-IDM. The results of the research indicate that the BO-IDM carries the potential of facilitating emergency response operations by, i.) overcoming the limitations of geospatial and city models regarding representation of semantic information required for better navigation and orientation and ii.) eliminating the non-geo-referenced structure and complex geometries of BIMs.
