A completely different project, as it is not airborne, is the "Scan2BIM"  project of the Zurich-Enge train station in Switzerland, which BSF  Swissphoto conducted together with Grünenfelder und Partner AG for the  SBB in the period April - October 2020. BIM stands for Building  Information Modeling and includes the detailed geometric but also  functional representation of buildings or infrastructure objects. The  goal of the project was to model the historic station complex in a level  of detail 200-400 based on terrestrial laser scan data. For the  acquisition of the 17'700 m2 large complex 1'500 scan positions were  necessary. Several thousand working hours were invested in the  subsequent modeling of all building elements, including lines and pipes,  in order to provide the client with the optimal planning basis for the  upcoming renovation and conversion work.
