Extending the 2nd S‑Bahn Main Line in Munich (GER)more
As part of a joint venture (JV), ILF has been awarded the contract for the preparation of tender documents for the Eastern Section of the 2nd S‑Bahn Main Line in Munich.
This section of the line comprises approx. 3.4 km of tunnels, one underground halt and several civil engineering structures. ILF has also been involved in the design of the Western Section of the line since 2017. As part of different JVs, ILF was commissioned with the final design and the permit application design services for the overall project, the preparation of tender documents and construction design services for two underground halts.
The overall project, with a line length of approx. 10 km, contains a tunnel section with a length of approx. 7 km and three underground halts (with lengths between 230 m and 250 m, and a depth of approx. 45 m). The tunnels – two tunnels and one emergency tunnel – will be driven mainly by TBMs. The underground halts are being constructed using the cut-and-cover method, and for the platform tunnels, the New Austrian Tunneling Method (NATM) is being used.
The Deutsche Bahn has taken the decision to extend the underground section of the line under the city center (by adding a new line beneath the existing one) because the S‑Bahn Main Line in Munich was no longer able to handle today’s passenger numbers.
