Stuttgart 21 – a Pan-European Railway Project
Established in 1850, the railway connection between Stuttgart and Ulm is no longer up to the demands placed upon it by the requirements of modern railway service. This section is part of the European high-speed railway route from Paris to Budapest via Strasbourg, Stuttgart, Munich, Vienna, and Bratislava. The Deutsche Bahn AG railway company, Baden-Württemberg state, regional traffic authority and Stuttgart city council, the German federal government and the European Union are currently implementing one of the most innovative and comprehensive railway projects in Europe, including 60 km of new permanent railway from Stuttgart to Ulm as well as the conversion of Stuttgart’s main station from a terminus to an underground transit station. Named Stuttgart 21, the project has a total investment of around € 6 billion, and is currently one of the world’s most demanding infrastructure projects.
A tunnel will connect the new underground transit station in the heart of Stuttgart to the airport and planned high-speed railway to Ulm with entry tunnels, some in open construction, as well as railway and road overpasses, trough structures, niches, new track and other engineering structures. The ring track underneath the city will substantially cut journey times for passengers. Commissioning of the Stuttgart-Ulm rail project is planned for the end of 2025.
The geotechnical and hydrogeological conditions of the Gipskeuper formation are exceptionally demanding as well as the location within Stuttgart’s drinking water and medicinal spring protection zone.
Our clients commissioned us with building assessment and geotechnical consulting throughout the city of Stuttgart in six planned approval stages throughout the tendering and construction phases in the project. Additional services include participation in the determination and evaluation of constructive solutions, quality assurance of tenders, support for the awarding of contracts, preparation of subsoil and foundation reports as well as the preparation of geotechnical and hydrogeological risk and malfunction analysis. The services also include the client’s geotechnical consulting regarding legally secured procedures as well as the the specialised site supervision and the assessment of the subsoil.
The construction management requirements for urban construction stages make this major project especially intriguing given the tight schedule and the highly complex regional geological and hydrogeological situation. We are using our experience in similar infrastructure projects together with our extensive knowledge of geotechnical project preparation in the semi-hard rocks of the region. With our specialist expertise we are making a valuable contribution to the success of this project.
