The so-called Audi tunnel, the line of the newly built ICE train connection between Nuremberg and Munich crosses a part of the company premises of the car manufacturer Audi underground. With respect to vibration-sensitive production plants, the idea of a mining-type blasting of the tunnel tube was no option. The construction was carried out with the cut-and-cover construction method instead. After the completion of the diaphragm walls and the bottom below ground, the outer tunnel walls were formed single-sided and concreted against the retaining walls.
