The aim of the project is the structured preparation of the planning and decision-aiding processes for the digitalization of building permit procedures. For this purpose, the actual processes at municipal and city level will be analyzed and compared with the processes of a fictitiously submitted pilot project. Finally, problem areas are identified, optimization potentials are shown and target processes are derived. The cooperation and involvement of other cities and actors in project workshops is explicitly envisaged in order to achieve a broad acceptance and dissemination potential.
