Confined conditions and obstacles in the ground require specialist civil engineering
Due to the high loads and the need to construct additional staircases, it had become necessary to stabilise the ground beneath the former department store. Before implementing the jet-grouted columns, a drilling rig was used to drill through the foundation slab. As the building was originally constructed on the filled-in city moat, the specialist civil engineering team encountered numerous obstacles in the subsoil. The space available to set up the construction site was extremely limited, not only in the basement but also in front of the building. In addition, as deliveries and waste disposal runs through the central Munich’s pedestrian zone were only permitted before 10:15am, logistics on the construction site required meticulous planning.
Mixed-use premises for Karlstor
Originally constructed as a hotel in 1865, the building known as “Herzog Max” is directly adjacent to the Karlstor, one of the old city gates, and is among the most frequently photographed buildings in Munich’s pedestrian zone. Its striking façade features Neo-Baroque and Neo-Gothic elements and has been preserved during the renovations, which will create 14,000m2 of state-of-the-art mixed-use space capable of satisfying the requirements of the modern working world.
