Walo Bertschinger AG was commissioned by the Sarganserland power plant to dredge sediments from a water depth of up to 50 meters in the Mapragg reservoir, Tamina Valley near Bad Ragaz.
Concrete rehabilitation and hydrodynamics
The construction of a new building was carried out at the old location of the hydroelectric power plant, and the Simme river was completely diverted in the process.
Reused gravel fill from the Rhine for ecological enhancement of riparian areas, stabilization of existing riparian structures, and protection from bank erosion.
The listed boathouse in Auried in Au was in a very dilapidated condition due to subsidence and leaning and was in need of urgent refurbishment.
The boathouse of the police patrol boat on the banks of the Rhine in Grossbasel was to be protected from floating debris. WALO received the order to erect a corresponding flotsam deflector.
