Westfield Hamburg-Überseequartier

The investment consists of 14 buildings, which are connected by a common 2-3-storey underground part. This area was divided by the U4 metro line with the Überseequartier station. Two underground floors were built to the north and three to the south of the metro station. Both underground parts have been designed as watertight foundation slabs. The southern part is connected to the construction of the diaphragm wall, while the northern part is connected to the palisade of drilled piles.

In the northern part, apart from commercial space, mainly residential construction is planned. In the southern part, office space and service premises have been designed, which will be located on the first underground floor and on the ground floor. Hotels, a cinema and office spaces are planned above. There will also be a bus station and a cruise terminal with a hotel designed above them.

There is a large two-storey underground car park under both the northern and southern parts. The adjacent parts are connected with each other by a two-storey link running over the subway tunnels. Due to the different purpose - cruise terminal, bus station, car parks, retail, catering, office and apartments - the large span beams and heavily loaded columns were very challenging. These elements were mostly designed as composite steel and reinforced concrete elements.
