Initial situation

Initial situation

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

Concept

Concept

To avoid disrupting traffic, the 228-meter-long underground car park is planned using the top-down construction method. This means that the majority of the construction work takes place underground, while traffic continues to flow on the deck above. The special feature of the site development at Alexanderplatz: The concept already provides through-routes and underground connections for delivery traffic serving future new buildings.

Result

Despite its enormous length and width, it is possible to largely do without pillars. The car park testers accordingly award it many top marks. The garage is a civil engineering structure of superlatives that noticeably strengthens the dynamism around the Alex and, as intended, stimulates further developments at the surface.

ADAC test: Berlin's best car park is beneath the Alex. The car park (…) scores points in the most important categories: safety, drivability, and user-friendliness.
