The German capital city is growing! With over 3.5 million inhabitants, Berlin is the biggest city in Germany and even decades after reunification, construction is still booming. New developments in the inner city are in particularly high demand. One such development is a 30,000 m² shopping and activity center in the Moabit district of Berlin Mitte – a once working-class district – on the grounds of the former Schultheiss brewery, steeped in tradition. The client, HGHI Schultheiss Quartier GmbH & Co. KG, is also building 6,000 m² state-of-the-art offices – almost half of which are listed as historical monuments. For the new-builds, Bauer Spezialtiefbau GmbH and JV partner Keller Grundbau GmbH constructed two complex excavation pits with a total area of 11,000 m² in confined inner-city conditions from May 2015 to November 2016.
