Tony Gee completed the construction engineering and temporary works design of the fixed roof erection for the new 55,000 seat multi-purpose National Stadium, and provided site supervision services throughout construction.

The structure has a heavy architectural influence; the roof spans 340m about each principal axis to give the crowd a completely unimpeded view of events. The structural members are tubular steel trusses, the interaction of which demanded high quality fabrication and site assembly. The roof skeleton was propped from temporary trestles during construction, some of which were up to 70m tall. Others were supported from the concrete frame for the terracing and thus limits had to be placed upon the load reactions at these locations.

Tony Gee undertook temporary works design and staged analysis to determine the locked-in forces during the construction. This included 3D finite element analysis on the complex connections during the erection process.

The temporary works were designed using existing ‘standards’ that the client already owned, meaning demand of new material was kept to a minimum.
