A new hotel complex consisting of two up to 7-storey tall buildings is to be built at the south-western end of the village of Zermatt, Canton of Valais. As the terrain in the project perimeter rises sharply, the access to the hotel will be via an access tunnel with a lift from the street level, which is approx. 40 m lower. Due to the very steep terrain, there will be vertical excavation cuts up to 20 m high on the slope side. In combination with the geological conditions (mostly unconsolidated rock), this project represents a complex geotechnical challenge.
