Sinergia Chur
Suspended steel staircase

The main staircase in the Sinergia Chur administration building, which runs over 5 storeys, was suspended from the top of the building's supporting structure using tension rods.

It was important that the staircase did not vibrate. This was ensured by means of calculations.

The staircase is structurally unique as it is elliptical in plan.
