The OBB Infrastructure plc commissioned our office with the elaboration of the planning documents for the removal of the avalanche protection roof “Bachfalle” (route Innsbruck – Bludenz, km 112,663 bis km 112,697) in Kloesterle (A).

The prefabricated roof and the supports on the south were removed. The reinforced concrete wall on the north side and the wing walls on both sides, which protrude the slope, were taken off down to the top edge of the slope.
