On Rigi Fruttli the old concrete bridge over the Rotenfluebach had to be replaced. The concrete bridge was more than 50 years old and no longer met the requirements. It was replaced by an innovative wooden bridge with a load capacity of 40 tons.
The task was to quickly replace and reuse the bridge. Together with the engineering office Edgar Kälin AG, Einsiedeln, we developed a hybrid solution with an HBV-System. The bridge slab was constructed with UHFB – ultra high performance fibre concrete. We solved the bond between the deck slab and the BSH-Beam GL32h with the GSA HBV-System.
