The structural grid is spaced at 7.5m to relate to the structural grid of the pier. Each section of the grid consists of a pair of piles on which rest a tapered 457 x 191mm universal beam and crossbeams, supporting permanent formwork and a cast in-situ slab floor. The canted 250 x 150mm RHS columns and V-shaped 250 x 150mm RHS columns rest on the tapered floor beams.
The two upper ends of the Vshaped columns slot into the undersides of the tapered roof beams. They are fabricated from 30mm-thick steel plate and support a series of 160 x 80mm RHS purlins and a standingseam aluminium roof covering.
The southwest facade is glazed with double-glazed units (19mm toughened glass, 12mm cavity and 6mm glass inner leaf ), which are supported by canted structural steel mullions.
The mullions are formed of paired back-to-back 75 x 150mm steel angles welded together with 20mm plates. The glass units rest on steel angles bolted to the mullions and are secured with 60 x 40mm steel angle beads screwed to the main angles with countersunk screws.
Where the roof beams project beyond the glazed facade, the paired back-to-back angles are welded together with a 230mm-wide plate, allowing the beam to slot between the angles. The mullions rise above the line of the beams and are bolted to the purlins. At their bases, they are bolted to projecting steel plates welded to the floor beam.
A steel handrail runs along the glazed wall. It is formed of continuously welded 100 x 50mm RHS members with tapered brackets that slot between the back-to-back angles of the mullions and are bolted to them.
