The Hochtief/ Alpine/ Wayss & Freytag JV is awarded construction of the 3.8km Bad Canstaat Tunnel as part of Germany's €6 billion Stuttgart-21 high speed rail project.
A consortium led by Stuttgart-based Baresel is awarded construction of the Feuerbach Tunnel. German rail operator Deutsche Bahn (DB) values the two contracts (PFA 1.5), which will complete the northern and eastern edge of a new rail ring around central Stuttgart, at €300 million.
The tunnels will also provide an extension to and link with Stuttgart's existing S-Bahn network. (Fig 2)

A €500 million contract (PFA 1.1) to build the access tunnels and platforms for the eight-track Stuttgart Main Station, which will be the hub of the entire project, is awarded to Germany's Zublin, a subsidiary of Austria's Strabag. (Fig 1)
According to DB, half of all contracts for the 57km Stuttgart-21 section have now been let, and 90 per cent of all the tunnels have been awarded. The 9.5km south-running Filderstadt Tunnel, which connects Stuttgart Main Station with the airport, was awarded to Porr of Austria last year.
DB Infrastructure Officer Dr. Volker Kefer said: "With these major awards for the new underground station and the tunnel to Feuerbach and Bad Cannstatt, we remain on target and on budget."
When complete the 57km Stuttgart-21 section, and the 60km Wendlingen-Ulm section it will join with, will cut journey times from 54 to 28 minutes. The improvements will also reduce longer-distance national and trans-European journeys on both east-west and north-south routes.
Almost half the 117km length will be tunnelled, a total of 21 tunnels of 500m or more. Additionally 38 bridges, 17 overpasses, three stations and one station conversion are to be carried out. The project is scheduled for completion in 2019.
