“This challenging construction order requires the extensive know-how of our ground engineering team,” said Strabag CEO Thomas Birtel. Work on the section at Sonnenallee Junction in Berlin involves the construction of a new dual-track commuter rail bridge and a single-track bridge for long-distance services. Each will have spans of 68m.

The company will also install diaphragm walls, establish underwater concrete floors, install uplift and pit-lining anchors, and drive sheetpiling and bored piles. The contract also encompasses the delivery and installation of 200,000m³ of concrete.

The work will be carried out with no interruption to rail service, necessitating the construction of several auxiliary bridges.

Construction is expected to be completed August 2017.
