Stuttgart, Germany / 01.2016 - 04.2016

On the major construction site of Stuttgart 21, ÖBA manufactured a concrete tunnel slab with a durable water trough and a cross section of 5.5 m.

The approximately 4.0 km long stretch with a cross section of approximately 4.0 m³/running metre was realised with an average performance of 150 running metres/day.

High tech underground.

This enormous achievement was made possible by a slip-form paver. It moves along the segment with a track system angled at 40°.

Technical equipment and experience were significant criteria for the customer in assigning this major project to ÖBA.

What ultimately counts in the construction business is successfully completed projects. PORR has many of these.
