Project Description

A large multi-use venue in Sydney for sporting and cultural events with a capacity of 42,500. The stadium showcases a distinctive, lightweight roof that covers all seats and is designed for disassembly and future reuse. The stadium seamlessly integrates aesthetics and structural efficiency with a prioritisation of sustainability through dematerialisation, reuse, and recycling and has achieved a LEED gold rating. Digital engineering techniques were implemented to optimise the design, quality assurance and construction efficiency within a tight schedule.

Judge’s comments

This world-class stadium boasts a technically complex roof which appears to float above the seating areas. Lighter than conventional stadia roofs, it uses up to 40% less steel, while still covering every seat and providing spectators with unobstructed views of the field of play. Combining the robustness of a mega-truss structure with the lightness of a doubly curved diagrid shell, the mixed structural system sets a new standard in large-span structures.

The roof embraces circular design principles and was designed for disassembly and reuse in the future. The design astutely accommodates essential services such as pipework, cables, lighting, and speakers, while conscientiously mitigating light spill and noise pollution.
