Underground construction

Precision at the deepest depths: To us, safety and accuracy are of the utmost priority in underground mining. No matter whether we’re working with detonators, excavators or other types of tunnelling equipment. We ensure we don’t only maintain the highest technical standards but also hold great respect for the rock substance itself – enabling us to deliver results that impact our surroundings as little as possible.

Underground construction

Stuttgart 21

ÖSTU-STETTIN is building the Filder Tunnel and the Ober-Untertürkheim Tunnel, with a respective length of 9.5 and six kilometres, as part of the centennial ‘Stuttgart 21’ project. They are important feeders for the terminus station, which will be transformed into an underground through-station when fully operational. Tunnelling under the Neckar River is a particular challenge in this respect.
