Extension of car park 6 –1'300 additional parking spaces

The project involved extending the existing car park 6 to the south by adding a total of four rows of parking spaces (Comfort Class B) to each level, providing some 1'300 parking spaces. The existing entrance was retained. Inside, the extension was connected to the existing circular ramp.

A new exit bridge was built to the south. Structurally, the extension is a composite steelwork/concrete assembly which is physically independent of the existing building, although the column grid was continued. The façade is clad with aluminium panels.

Four additional emergency exit staircases and four new lift systems were built. Smoke exhaust systems were added to extract smoke from the inner stairways. On the basement levels, ventilation/smoke exhaust systems and sprinklers also had to be installed.
