Initial situation

Initial situation

Project development and investment at Berlin's Alexanderplatz came to a standstill in the early 2000s. Mobility infrastructure is an effective lever for location development. A large and modern underground car park is to reactivate plans for new high-rise buildings.

The concept

The concept

To minimise disruption to traffic, the 228-metre-long underground car park will be constructed using the cut-and-cover method. This means that most of the construction work will take place underground, while traffic continues to flow above ground. The special feature of the Alexanderplatz site development is that the concept already includes passages and underground connections for the delivery traffic of future new buildings.

The result

Despite its enormous length and width, the car park is largely free of columns. The car park testers gave it top marks. The car park is a superlative underground structure that has noticeably increased the dynamism around the Alex and, as planned, triggered further developments on the surface.

ADAC test: Berlin's best car park is located under the Alex. The car park (...) scores well in the most important categories: Security, accessibility and user-friendliness.
