The both halls, which are located on a 14 hectare plot, are massive constructions with reinforced concrete columns and a base slab made of fibre and reinforced concrete on a sleeve foundation. The facades are clad with reflective white aluminium panels. Each volume has its own function. Two test centres for large scale bearings as well as two smaller test centres are located in the higher one-storey hall. An overhead crane for 110 tonnes ensures the levelling of the highly sensitive mechanical components.
