KÖ Bogen IIAn important milestone was reached on May 9; CENTRUM from Düsseldorf and the B&L Group from Hamburg will celebrated the topping out of Kö -Bogen II in the presence of ingenhoven architects. At the same time, the foundation stone was laid. Carrying out the building construction and the civil engineering at the same time is not just unusual, it also demands top performance in terms of construction technology. This is required to make it possible for the completion of the shell construction above ground (topping out) and the insertion of the base plate at a depth of 17 meters below ground (groundbreaking) to coincide. Both the topping out celebration and the ground-breaking ceremony are on time, and the scheduled opening of Kö -Bogen II in the spring of 2020 is assured.
