Fehmarn Sound Crossing

Project and structural planning for the variant ”bore tunnel” of the BIM pilot project

With the German-Danish arrangement on the construction of a ”solid Fehmarnbelt crossing”, there is a challenge on the German side to produce a well-performing street and rail connection. A part of this project are the two-track expansion and the electrified upgrade of the existing railway line ”Lübeck-Puttgarden”, as well as the four-lane expansion of the federal road B 207 between Heiligenhafen-Ost and Puttgarden.

The Fehmarn Sound Bridge currently proceeds through a combined streets and railway bridge structure. In order to fulfil the requirements set concerning performance and safety for the future traffic, DB Netz AG and the state of Schleswig-Holstein (LBV-SH), in agreement with the Federal Ministry for Traffic and Digital Infrastructure (BMVI) have decided upon realising a new, solid connection of the isle of Fehmarn with the mainland. Within the border of the pre-planning, four variants of a new Fehmarn Sound Crossing are to be investigated.

ZPP, providing technical lead management in a bidding consortium, is commissioned with the pre-planning of the variant ”bore tunnel”. Aside from the services of project and structural planning within the first two service phases (in accordance with HOAI), ZPP is also entrusted with the BIM coordination of the services rendered by the bidding consortium. Furthermore, the bidding consortium is rendering the services for the project planning - traffic installations as well as specialist planning - technical equipment over the course of the pre-planning process.

Two electrified railway tracks, four lanes of the federal road, the slowly progressing traffic as well as a combined walk- and bike way are integrated into the planning and design concept.
Over the course of the complete routing with up to 9 km, at a length of approx. 2-5 km, tunnel structures via trench less construction method, as well the required ramp areas via cut-and-cover method are included. The planning is based on a water level that is approx. equal to the ground level.
