Generation of new BIM domain models from escape route analysis results

The Industry Foundation Classes (IFC) schema is an open format for BIM models that secures permanent data availability independent of software vendors. This is particularly important for public stakeholders such as building authorities. However, during code compliance checking of the permit process, new explicit data are generated from information implicitly contained in the building models. This information has been available only in the checking application used and not independent of it. This paper presents an approach for generating a new IFC domain model from generated escape route results to be used by the building authority. This was achieved by defining the general concepts of how escape routes can be represented by building models and mapping these to IFC entities. A prototype implementation demonstrated the applicability of this approach. In addition to independent permanent archiving, the IFC domain model for escape routes enables the use of this data during building operations.
