This challenging structure required 3D design methods that transferred all details to the fabricators directly. Such an approach guarantees the right economic and technical conditions for an ideal realisation. Mounted on top of the primary structure of curved steel circular hollow sections is a framework of aluminium sections that follows the polygonal line of the roof surface. Together with the secondary members they form the network of trapeziums that supports the glazing. Aluminium strips cover the joints parallel with the slope of the roof and produce a finely structured roof surface. The horizontal joints are sealed with silicone only in order to guarantee no interruption to the water run-off. Additional point fixings secure the panes against wind uplift.
The fully glazed link at the northern end shows a degree of constructional finesse. Load-bearing brackets project from the edges of the reinforced concrete floor slab to support the vertical glass fins that carry the entire load of the glass façade. The roof to the bridge is also completely of glass. Five parallel glass fins 8.5m long form a stable supporting construction for the large-format panes overhead.
