Object description:

Since Zermatt was cut off from the outside world by several avalanches in the avalanche winter of 2018, an avalanche deflection dam is being built. The project includes the construction of the avalanche deflection dam and the creation of a construction slope. This dam will be built to protect the population from avalanches.

Special requirements:

• Working time only possible from summer to autumn, due to avalanche danger.
• The construction site was only feasible with well-trained and experienced personnel
• Removal and application with 3D excavators
