The Singapore Sports Hub is a key project in Singapore’s urban redevelopment and sports facilities masterplan, which promotes a more sustainable, healthy and active society. The Hub provides a unique ecosystem of sporting, retail and leisure spaces, including the new National Stadium - a highly adaptable, state-of-the-art, 55,000 seat sports venue featuring a retractable roof and movable seating. The Hub is the largest free-span dome structure in the world, and the stadium sets new benchmarks in efficiency of design and material usage – the roof uses a third of weight of steel normally used in a span of this size.
The structural solution for what is now the world’s largest free-spanning dome is a testament to ultimate design optimisation and architectural-engineering collaboration. Parametric design tools were used to achieve a super- efficient, functional design as well as a simple, yet striking architectural expression.
