Singapore National Stadium Mode Change - Football to Athletics

The Singapore National Stadium is the world’s first air-cooled and custom-designed stadium that can host athletics, football, rugby and cricket all in one venue, converting from one mode to another within a mere 48 hours. Arup designed an integrated moving tier system which achieved an optimum viewing experience for spectators during sporting events.
Divided into eight retractable seating modules, the 55,000 seat National Stadium has 30,000 seats located within the lower tier bowl, bringing spectators closer to the action.
