Lindner designed, manufactured and installed curved metal ceiling systems and 20 curved metal bulkheads. The curved bulkheads are in a sweeping form curving back with arching / flowing tops to the panels to create a complimentary (although deliberately inconsistent) effect to the glass roof over the malls.

The whole design was produced in 3D CAD and then transferred to manufacture.
Despite the numerous number of panels, no single panel was made incorrectly (an outstanding achievement for such a complex design).

The curving bulkheads at level 60 were complimented by the curving ceilings on level 40 incorporating hinge down access facility. Metal was chosen after Lindner had produced a large scale mock-up and recognised the undeniable.
