The Olympic Delivery Authority (ODA) says that construction is now 75% complete and the main venues are on track to be completed next summer – a year before the Games.
New aerial photos of the Olympic Park show progress on the main venues.
ODA chairman John Armitt said: 'This year is the toughest in terms of construction and we are at our busiest. We will enter 2011 with the confidence that more than three quarters of the construction project is complete and that all milestones to date have been achieved.
'We remain on schedule and within budget but are not complacent about the challenge that lies ahead.'
Recent progress made on the main venues includes:
Olympic Stadium: Structurally complete with roof and lighting towers in place. Work close to completion on installing the seats. Ready to start laying grass and the installation of the running track next year.
Aquatics Centre: Permanent structure and wave-shaped roof in place, work underway on the Games-time temporary seating stands, ceiling timber cladding and bespoke concrete dive boards. The dive pool and two 50m pools have been tested and tiling is underway.
Velodrome: Structure is complete and watertight, and the timber track is being installed. On target to be the first Olympic Park sporting venue to be completed in early 2011.
Athletes' Village: More than three-quarters of the residential plots are structurally complete, with the structure of the Chobham Academy school also nearing completion. Work is well underway on the polyclinic. First stage of landscaping has started.
International Broadcast Centre/Main Press Centre(IBC/MPC): The structures of the IBC, MPC and Multi-Storey Car Park are all complete. Mechanical works are progressing inside both the IBC and MPC and works have started on the temporary ‘high street’ for journalists and broadcasters during the Games.
Handball Arena: The structure of the Handball Arena is complete and weather-tight, with the roof – fitted with natural light-pipes to illuminate the venue - also finished. The top half of the building is now being clad in 3,000 sq m of copper cladding.
