The Olympic Stadium has begun work on the playing field marking a major landmark in the £537 million venue.
Construction of the structure is already completed and the focus has switched to laying the ground and track where the opening and closing ceremonies will be held.
Before any track and turf can be laid a complex system of ducts and drainage must be installed which is expected to be completed at the end of the year.
Olympic Delivery Authority chair John Armitt said: "Only two years ago, the stadium site was a flat piece of ground.
"A huge amount has been achieved since then, with the venue now structurally complete and at its full height.
"Work is progressing on covering the roof and the first seats will be fitted this summer. The continuing progress means the stadium is still on track to be completed a whole year before the 2012 Games."
With over 12,000 concrete seating terracing units in place, installation of the black and white seating will begin this summer at the East London stadium.
