The scope of works comprised of the installation of a structural steel mid-tier deck, high level walkway and pavilion, plus the structural steel framing for the iconic floodlight gantries that support the lighting for the arena. The mid-tier was formed from deep tapering fabricated girders with cantilevers attached to the original seating raker beams and supported by new props. The curved geometry and connections led to careful surveys to allow for scope tolerance. The high level walkway interfaces with faceted and raking members. This required careful survey and extensive site works to ensure accurate installation.
