Support System Erzherzog-Johann-Hütte, Großglockner (Austria)

Project overview:

The “Erzherzog-Johann-Hütte” is a refuge at the so-called “Adlersruhe” on the Großglockner (at 3.798 m above sea level, Austria's highest mountain). It was built in 1880 and since then extended consistently. Especially in the oldest parts of the cottage, cracking of the masonry occured and dripping water had been observed. Detailed inspections and investigations revealed that the building is partly founded on rock mass, partly on frozen detritus. The cause of the suffered damage was seen in the constant creep of the glacial mass.

Under the extreme boundary conditions of this project in high alpine environment (extreme weather conditions, transportation of material and tools by helicopter only, short construction time, permafrost soil conditions) our company developed a cost-effective and long-lasting support system for the refuge.
