The model shows a reinforced concrete building complex in Hamburg's HafenCity with an 18-story office high-rise, a 7-story office building, a 9-story residential building, and a two-story underground car park. The design considered the influences of multi-story construction and the requirements for vibration decoupling due to the U4 subway line. RFEM was used for the calculations. The client, grbv Ingenieure im Bauwesen GmbH & Co. KG, was responsible for the structural design of the building and excavation. The 3D model visualizes both the high-rise and residential areas.
