The Olympic Stadium is located on a 40-acre island surrounded by waterways on three sides and will have a capacity of 80 000 during the Games. Most of these seats can be removed after the Games are over thanks to the specially designed lightweight upper tier.
More than 30 buildings were demolished to make way for the construction of the venue and 6 500 cubic metres of crushed concrete – recycled from other parts of the Olympic Park – was spread on top of the ground to create a solid platform for the construction of the Stadium’s foundations.
Only 10 000 tonnes of steel were used to build the venue, making it one of the lightest and most sustainable Olympic Stadiums ever built. It took six weeks to lift the 450 tonne roof structure into place.
