The use of BIM is becoming increasingly important in the AEC industry because the included dataset enables the automation of many processes. One emerging application of BIM is the automation of building code checking by building authorities. Building code checking is a time-consuming process, particularly for escape routes. Therefore, its automation promises considerable optimisation potential. This study presents a semi-automated escape route analysis for building code checking. Our developed concept consists of two automated steps, with a legally required manual step in between: (1) escape route generation, which provides possible routes from which designers can select a valid combination, and (2) escape route validation, which checks the selected combination of escape routes for validity. The basis of both automated steps is a novel indoor navigation model. We implemented the concept in Solibri Office and validated it with real-world models. The developed escape route analysis method shows potential to improve designers’ escape route planning and building authorities’ escape route checking.
