THE bare roof of the Olympic 2012 stadium has now been lifted into place, as organisers claim the project is on track to open on schedule next summer.

Over the last four weeks 56 hydraulic jacks have been used to lift the 450 tonne cable net roof into place.

The cable net roof will later be covered with material to keep rain and wind out of the stadium.

John Armitt, Olympic Delivery Authority chairman, said the completion of the cable net roof was a “milestone”.

Mr Armitt said: “It has been a complex engineering and construction challenge, complicated by the wind and rain in recent weeks.

“We remain firmly on track and will lift the lighting towers into place early next year, taking the stadium to its full height. “
