Max and Moritz, residential district

For the construction of the residential district with 60.000 m2 of floor area and the two distinctive high-rise buildings Max (26-storeys) and Moritz (23-storeys) in Berlin-Friedrichshain extensive ground investigations were carried out with the help of drilling and pressure probing.

The skyscraper were each established by means of a combined pile foundation (KPP) under the protection of a watertight excavation pit with back-anchored diaphragm walls and a jet grouting column.
