Residential building Pandion Wall

The residential and commercial building in the center of Berlin was built as a reinforced concrete structure with one lower floor and eight upper floors on a bored pile foundation. A subway tunnel runs a short distance to the construction site (Line U2, minimum distance to the construction project approx. 6m). The tunnel ceiling is approximately at the level of the planned building sole. The high demands on living comfort permitted only low vibration and secondary airborne noise immissions. During the construction work, an on-site vibration monitoring to secure the subway tunnel was required.
