Tunnel and station construction orders placed by Deutsche Bahn

In mid-March Deutsche Bahn awarded contracts for further tunnel structures and primary construction of the underground station for Stuttgart 21.

The contract for project approval section PFA 1.1 – underground station (valley crossing, station access tunnels, and western / Cannstatter Straße and Nesenbach culverts) worth approximately EUR 300 million was won by a
consortium headed by Züblin of Stuttgart.

PFA 1.5 (primary construction of Bad Cannstatt and Feuerbach tunnels) costing around EUR 500 million is being
awarded in two lots. The order for construction of the Feuerbach tunnel was won by a consortium of bidders headed
by Stuttgart-based medium-sized businesses building contractor Baresel. The contract for work on the Bad Cannstatt was awarded to a consortium headed by the Hochtief company.

According to DB Infrastructure director Dr Volker Kefer, this means orders have now been placed for 50 per cent of the total construction work and 90 per cent of the tunnelling. Contracts worth a total of around EUR 700 million for two
sections have already been awarded to a consortium headed by the Porr Group: the Filder tunnel (PFA 1.2) and
the Ober-/Untertürkheim tunnels (PFA 1.6a). Both projects consist of two single- track tunnels. The 9.5 kilometre
long Filder tunnel connects the future underground station to the airport.

The tunnels Ober- and Untertürkheim, totalling some six kilometres in length, pass below the Gablenberg district after
leaving the station and, after passing below the River Neckar, fork off towards the Untertürkheim/Bad Cannstatt yard and towards Obertürkheim, where the track joins the existing line to Göppingen/Ulm.
