DB Netz awards €189m contract for 2nd main line of Munich S-Bahn system


November 21, 2018 – A consortium comprising Ed Züblin, Wayss & Freytag Ingenieurbau belonging to the Royal BAM Group, Max Bögl Foundation and Bauer Spezialtiefbau has won a first, €189m contract from DB Netz for the main construction of the second main line of Munich’s S-Bahn system.

The consortium will be responsible for the construction activities of the ‘Overground West’ project, from the Laim station to the Donnersberger Bridge.

The contract includes the dismantling and construction of new tracks and switches, construction of two viaducts, a twin-track steel arched bridge and a noise barrier bridge.

New noise barriers, support structures and the environmental crossing (Umweltverbundröhre or UVR) will also be constructed in Laim.

The project includes the renovation of the station Laim, electrical works for low-voltage and medium-voltage installations, cabling works and site preparation works for the West Tunnel portal.

The designing works for the project will commence later in November 2018 and the construction works in 2019.


Currently, there are additional bidding procedures for the main construction works for the West Tunnel project with the main railway station and Marienhof station, and these works will be awarded in the coming weeks.

DB Netz overall project manager Markus Kretschmer said: “I am pleased that we can now award the first contract for the main construction works. With the consortium, we have gained competent partners for the construction of the second main line. So we can now start into the next phase of the construction activities.”

Earlier in September 2018, Münchner Stadsentwässerung, which is responsible for the construction, operation and administration of Munich’s sewer system and wastewater treatment plants, has awarded Wayss & Freytag Ingenieurbau a contract for two wastewater tunnels in Munich.

The contract value is around €20m. Construction works have started and Wayss & Freytag Ingenieurbau expects to complete the project in 2021.

The two tunnels have a total length of 2,180 metres and will be constructed at seven to 12 metres below the Landsberger Straße in the west of the city.

Wayss & Freytag Ingenieurbau is deploying a hydro-shield tunnel boring machine with an external diameter of 3.6 metres for this purpose. The project also includes the construction of various shafts.
