here ya go some details...
Is there anything particularly innovative about the Olympic Stadium designs? The design has been conceived with two roles in mind - a full blown 80,000-seater arena in Olympics mode, substantially reduced to 25,000 seats in its 'legacy' role.
The stadium will be the showpiece of the Games
It has been designed to allow that transition to happen, with temporary seating and roof, that can be re-used.
The design therefore needs less steel than others of a similar size. It also benefits from the inherent stability of being built into a bowl.
The main innovation is the use of an 860m fabric wrap around the outside of the stadium, (the same as 72 London buses) which will be creatively lit with images projected onto it to give it vibrancy and a 'life of its own.'
Afterwards, the fabric will be cut up and turned into souvenir bags!
What happens to the stadium after the Olympics? Big changes to the proportions, as already described.
It keeps the athletics track and provides a permanent home for major track and field events.
It will also be accessible to the local communities in the five surrounding boroughs and an anchor tenant is being sought to help pay the maintenance bills.
That might be a football club, Leyton Orient perhaps, or a rugby club such as Wasps or Saracens.
Those negotiations are continuing, but not complete, and it will become a source of major concern if they can't sort that out over the next five years.
