The dome of the sports stadium, stretches 310 meters to cover the 55,000-seats.

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. 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.

Arup in a press release, explains:

The dome uses a “third of weight of steel normally used to span this size.” To provide shade during sporting events, is retractable and features “an energy-efficient cooling system that delivers cooled air to every seat.”
