Nytt S-Bahn-rute for avlastning

The Second Core S-Bahn Route project in Munich aims to alleviate the congestion on the city's primary S-Bahn line, constructed for the 1972 Olympic Games, which has now reached its capacity limit of approximately 840,000 passengers daily. The new route will serve as an alternative in case of disruptions on the main line and aims to reduce travel time from west to east of the city through the introduction of an express S-Bahn system. This project highlights the importance of enhancing public transport infrastructure to improve urban living standards.

733 Tunnel Ostbahnhof-kontrakt tildelt

The '733 Tunnel Ostbahnhof' contract, a significant component of this larger project, has been awarded to the joint venture 'Tunnel Ostbahnhof,' which includes Implenia and HOCHTIEF, each with a 50% stake. The contract, valued in the high hundreds of millions of euros, necessitates extensive structural work for the Ostbahnhof stop and tunnel tubes extending between Marienhof and Ostbahnhof. The overall project execution includes constructing two main traffic tunnels connected by transverse passages and a central rescue and exploration tunnel. Additional infrastructure covers the München-Ost underground station, various connecting structures, galleries, and underpasses at Ostbahnhof.

Tunnelbygging starter juni 2025

Construction of the 3-kilometer tunnel is planned to begin in June 2025, with project completion anticipated by May 2033. Building the stretch tunnels will involve tunnel boring machines (TBMs), while the transverse passages will be constructed using the New Austrian Tunneling Method (NATM) and supported by ground-freezing techniques. The rescue shafts and the deep-level station at Ostbahnhof will employ open construction methods. The implementation of Building Information Modeling (BIM) and Lean construction methods is expected to streamline the project.

Optimal koordinasjon i bykjernen

This complex urban infrastructure project demands optimal coordination across various civil engineering disciplines due to its busy city-center location and the need to maintain ongoing train traffic. The project poses challenges related to logistics, compact site setup, and required collaboration among special foundations, civil engineering, and tunneling units. Implenia leads the commercial aspects, while HOCHTIEF takes charge of the technical aspects of the joint venture, continuing their successful collaboration since 2018.

Budsjett 951 millioner CHF

Financially, the project involves substantial investment with a budget of 951 million Swiss Francs. The project is expected to bring significant societal benefits by expanding the S-Bahn network and enhancing connection capacities, addressing the increasing demand for efficient public transportation in Munich. It underscores the commitment to maintaining and developing high-quality urban infrastructure to benefit the city's residents and visitors.
