Abstract: “Linthal 2015” is as more than 1.5 billion project in the eastern Alps of Switzerland to expand an existing hydro power plant. Several construction sites are located in the area at an altitude between 900 and 2500 m above sea level which are operated in three shifts 24 hours 7 days a week. The winter in this particular region is normally long and snow rich and most of the construction area is exposed to natural hazards. Workers and infrastructure as cable ways, digging machines etc. have to be protected against stone falls and avalanches. The avalanche prevention is a central element for the working site management and the builder company has installed an avalanche service organization which analyses the situation and decide about possible measures like artificial avalanche release or even closing of the site. Different protective structures were established. Since in the past the area was not of interest and deserted during the winter, all experience with snow, weather and avalanches has to be built up new. This paper gives a brief description of the project, its different working areas and the avalanche service organization as well as the artificial avalanche release methods.
