London 2012 Olympic Stadium
An Olympic Stadium with such a large removable element and mix of permanent and temporary seating has never been attempted before.
The Stadium is also the most sustainable ever built for an Olympic Games. The lower tier sits within a bowl in the ground, which minimises the use of construction materials. This bowl was created by excavating 800,000 tonnes of soil, the majority of which was cleaned and reused elsewhere on the Olympic Park.
Around 10,000 tonnes of steel were used to build the venue –
significantly less than in other Olympic stadiums, making its
construction more sustainable. The top ring of the Stadium was built
using surplus gas pipes – a visual testament to London 2012's efforts
to 'reduce, reuse and recycle'.
Construction began in May 2008 and was completed in just under three years, with the final piece of turf laid in March 2011.
The Olympic Stadium in Olympic Park in Stratford, London, England was the centrepiece of the 2012 London Olympics, the last stop in the 2012 Olympics torch relay, and the venue of the athletic events as well as the opening and closing ceremonies. It is the central venue of the 2012 London Paralympics. It is located at Marshgate Lane in London's Stratford district in the Lower Lea Valley. The stadium has a capacity of 80,000, making it the third-largest stadium in England behind Wembley Stadium and Twickenham Stadium. Land preparation for the stadium began in mid-2007, with the official construction start date on 22 May 2008, although piling works for the foundation unofficially began four weeks ahead of that date. The stadium will also host the 2017 World Championships in Athletics.
