Scientific work in the digital age is hardly conceivable without disciplinary networking. New digital methods and technologies in civil engineering, architecture and urbanism (BAU) are closely linked to complex digital models, processes and data of their objects of investigation. In this context - funded by the German Research Foundation (DFG) - the specialist information service (FID) BAUdigital is being created as a sustainable digital platform to support scientific communities in networking, research data exchange and publication.
