Arcadis Mobility Germany, Signon Deutschland and IB&T Software have launched a technical partnership for joint projects in digital planning within the railway and transport sector. The aim is to create a BIM-compliant integrated system that delivers technically sound and economically viable planning results. The focus is on the software solutions ProSig, Signon OLAcad and card_1. By harmonising the technical interfaces, users are supposed to be able to manage cross-disciplinary digital planning more efficiently. The companies will remain independent in their respective business areas and will continue to offer their products and services separately. The collaboration is aimed at establishing a seamless, BIM-compliant workflow for railway planning, routing alignment, control-command and signalling (CCS) technology, as well as overhead line planning. In addition, the partners aim to further develop new technical applications.
