📋 Tender Overview
Deutsche Bahn uses the innovative Building Information Modeling BIM working method for the Offenburg tunnel. With this method the project is planned completely on computers in advance. A digital three-dimensional model is created of every building. The building data becomes more and more detailed as the project phase progresses. The 3D models also receive planning and construction information such as deadline and cost data. The benefit the effects of plan changes can be assessed directly both in terms of time and money. That makes planning and building more effective.Plan virtually build in real lifeWith BIM everyone involved works on the same central data platform. This promises more transparency and simplifies collaboration in all project phases. Planning approval execution and commissioning all from one source. This means that everyone involved is always on the same page. Another benefit of BIM The 3D models are much clearer than the classic plans. This gives the public a better understanding of the projects and increases acceptance.Digital illustration of the routeIn order to digitize the planning the railway carried out a total of eight inspections with measuring vehicles. The main tracks of the Rhine Valley Railway and the existing new line between the Appenweier station and the Niederschopfheim overtaking station were recorded. For the BIM planning Deutsche Bahn collected data with three laser scanners and two special cameras. The result is the digital mapping of the entire route. An existing model of the rail infrastructure is created on this basis. This will improve and optimize the planning of the route and for the Offenburg tunnel.The longest tunnel in the major projectThe Offenburg tunnel is part of the approximately 200-kilometer upgraded and new line from Karlsruhe to Basel. It is eleven kilometers long and lies to the west of the city of Offenburg. The structure is planned with two single-track tubes. After completion it will mainly be used by freight trains. Advantage for the region The residents inside are optimally protected from rail noise and vibrations.
