The single-story hall is located amidst heritage-protected buildings on the SBB Repair Center site in Zurich-Altstetten. A traverser allows railway wagons or locomotives to be moved under the hall roof. The new roof provides space for storing wheelsets and recyclables. The load-bearing structure of the roof rests on six cast-in-place concrete columns. This structural design allows for high flexibility for future uses.

Swiss Steel Construction Award Prix Acier 2018

The single-story warehouse has floor plan dimensions of 24.1 m x 53.5 m with a clear height of 7.8 m. The steel roof structure consists of rolled steel beams that span the hall in the transverse direction without columns. The main beams, arranged at intervals of 8.8 m, are supported along the longitudinal facades by a steel truss. Each steel truss rests on three cast-in-place concrete columns, meaning the 1,300 m2 roof is supported by only 6 columns. The hall is stabilized by the frame action of the six cast-in-place concrete columns fixed into the foundations, thus eliminating the need for continuous wall bracing. This guarantees a very flexible design for future use of the hall. A 3.2 t crane runway spans approximately 22.7 m in the transverse direction and runs the entire length of the hall, with the top of the crane rail at a height of approximately 6.6 m above the hall floor.
