The extension to car park 6 is being built as a replacement for car park 5.
The project involves extending car park 6 to the south by adding a total of four rows of parking spaces (Comfort Class B) on all floors, providing some 1,300 parking spaces. The current entrance will remain the same. Inside, the extension will be connected to the existing circular ramp. A new exit bridge will be built to the south.
Structurally, the extension takes the form of a composite steelwork/concrete assembly which, while continuing the column grid, is physically independent of the present building. The facade will be clad with aluminium panels.
There will be four additional emergency exit staircases and four new lifts. Smoke exhaust systems will be installed to remove smoke from the internal stairs.
The scheme necessitates the installation of additional ventilation/smoke exhaust systems plus sprinklers on the basement levels.
