Vienna Metro lot U2-17,
Austria

This project was realized by the engineering office laabmayr.

Lot U2-17 comprises the extension of Metro link U2 from the Altes Rathaus station to Matzleinsdorferplatz.

Services:

• Structures: TBM drives, emergency exits at Reinprechtsdorferstraße, Kaunitzgasse and Augustinplatz.
• Design: Alignment optimisation, consents design, tender design, preparation of tender documents, tender evaluation, detail design and as-built records, including design coordination in all phases.

The entire project includes two 3.3km-long running tunnels and the stations Matzleinsdorferplatz, Reinprechtsdorferstraße, Pilgramgasse and Neubaugasse.

The new route also includes three crossovers, which also serve as emergency exits, and a run-around at Matzleinsdorf.

The run-around and the station tunnels are to be constructed by NATM. Prior to the tunnel drives, the groundwater level will be drawn down using bored wells. The running tunnels will be constructed using a earth-pressure-balance TBM.
