Video | Transformation of the former Olympic Stadium

Three timelapse videos have been released of the former 2012 Olympics stadium being transformed into a all-year-round event venue.

Work at the stadium, now the centrepiece of the Queen Elizabeth Olympic Park, has included the removal of the original roof and light paddles and installation of a permanent roof, said to be the largest of its kind in the world.

The 45,000m² cantilevered roof needed significant strengthening to support the 8km of cable net, 112 steel rafters, 9,900 roof panels and 14 light paddles - which each weighed 45t. The new roof covers all 21,000 seats in the smaller venue.

London Legacy Development Corporation (LLDC) chief executive David Goldstone said: “We have invested in transforming a temporary athletics venue into a permanent world class multi-use arena that has a secure and long-term sustainable future. This has required a significant amount of work and innovative engineering solutions.”  

The LLDC this week revealed the cost of the conversion scheme had rocketed from £190M last October to £272M now. Main contractor Balfour Beatty insited its contract value remained just under £190M.

Olympic Stadium transformation: What the project involves

  • Installing a 45,000m² cantilevered roof – twice the size of the original – covering all seats
  • Strengthening work to the superstructure to support the weight of the new roof
  • Installing a cable net formed of 6km of steel cable weighing 930t to support the roof
  • Installing 5,423 pieces of steel weighing 3,900t 
  • Fitting 6,300 insulated rear panels to improve acoustics and 3,600 translucent polycarbonate panels at the front of the roof
  • Installing 14 floodlight paddles weighing 45t and housing more than 540 lamps
  • Fitting retractable seating for 21,000 spectators
  • Building 16 executive boxes and 3,600 corporate hospitality seats
  • Building 995 toilets, 90 new turnstiles and 35 catering outlets 
  • Installing a new Desso pitch with under soil heating and drainage
  • Providing up to 428 wheelchair user accessible viewing spaces
  • Refitting the interiors including dressing rooms, medical facilities and kitchens 
  • Building a 400m six-to-eight-lane community athletics track and 500-seat stand
  • Landscaping works around the Stadium complex
