Piles and grout prepare station for academy role

WorldWatch

BAUER SPEZIALTIEFBAU is carrying out extensive foundation work to safeguard the historic Kaiserbahnhof Railway Station in Potsdam, Germany.

The station was built by master court builder Ernst Eberhard von Ihne between 1906 and 1909 in the style of a country house, its main feature being a large reception hall alongside the platform.

After the Second World War, a Russian wide gauge track was laid into the station to provide Stalin with a direct connection to the Potsdam Conference and later for Soviet forces in the former German Democratic Republic to travel back to USSR on leave.

Kaiserbahnhof fell into disrepair but is now being restored and rebuilt to become an academy for Deutsche Bahn managers.

Bauer's work involves underpinning and in places creating new foundations for the original structures, as well as for the academy building.

The firm is installing a contiguous bored pile retaining wall of 130 piles up to 18m deep, plus 130m of jet grouting to seal the wall and 300m 2of jet grout underpinning for the building.

It will also install 40m of secant bored pile wall to 9m, and 130, 15m long ground anchors as tie-backs for the retaining walls. Another 165m of sheet pile wall will extend to 15m and 350m of king pile wall to 4m.
