BIGGEST INNER-CITY EXCAVATION PIT IN EUROPE / WORKS DURING ONGOING SUBWAY OPERATION
Excavation pit for a superlative shopping mall
The Mall of Berlin was built in the middle of Berlin-Mitte from 2011 to 2014, also known as the LP12 Mall of Berlin or the Leipziger Platz Quarter. The shopping mall has around 270 shops as well as the largest gastronomy area in the capital.
BTB was commissioned to excavate what was at that time the largest inner-city excavation in Europe. We removed 800,000 tons or 400,000 m³ of earth. At peak times, a truck with 26 tons of excavated earth left the construction site every minute.
In addition to the unbelievable size of the excavation pit, the U-Bahn (subway) line 2 that crossed over the site was also a particular challenge. It ran at a depth of 10 meters, whereas the construction pit was 20 meters deep and therefore had to be excavated around the tunnel. The subway ceiling was carefully removed with a concrete cutting wheel, while the subway was still in operation! 20 years earlier, we had already demonstrated our skills in such a complicated demolition when the U5 was built.
