The Singapore Sports Hub has been awarded the Supreme Award for Structural Engineering Excellence, the highest award given out by the Institution of Structural Engineers (IStructE) at their annual Structural Awards. The award honors the best example of structural engineering design entered during the year.
The sports stadium features the largest free-spanning dome in the world, stretching 310 meters to cover the 55,000-seat stadium, and uses a “third of weight of steel normally used to span this size,” writes Arup in a press release. To provide shade during sporting events, the dome roof structure is retractable and features “an energy-efficient cooling system that delivers cooled air to every seat.”
“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,” stated the jury. “Parametric design tools were used to achieve a super- efficient, functional design as well as a simple, yet striking architectural expression.”
