The building complex with 127 residential units and a business unit as well as an subway car park with 88 double parking facilities was built at a distance of 4-5 meters to a subway tunnel. Tunnel ceiling and building foundation are located below the groundwater level, approximately at the same height. The subway tunnel is served by lines U1 and U4. The tunnel has four tracks with curves and joints at different altitudes. For the residential building complex measures were required to reduce the vibration and secondary airborne noise immissions to meet the high comfort requirements.
