Object description:

The hazard map "Rock and Blockfall" for the area Grossstei - Rormatta was revised. During the revision it was determined that a large part of the year-round populated area lies in the red danger zone. The municipality of Embd has prepared a construction project to ensure the protection of the residents. A new dam will be built in the area of the existing turning area to the east (55.00m). The embankment will be built by means of an earth-reinforced supporting structure. Before the embankment is built, some preliminary works have to be done.


Special requirements:

  • Tight space conditions
  • 3D model on excavator
