The IOC Coordination Commission was making its fourth visit to the capital, meeting with representatives from across London 2012 and seeing first-hand the progress being made on construction of the venues.
Speaking after the meetings, Commission Chairman Denis Oswald said: 'We have been greatly impressed by the good progress that London 2012 has made since our visit last year, particularly in moving from planning to operational delivery.
'This was evident in all the presentations and discussions we had about LOCOG’s Games-time planning, and of course during our visit to the Olympic Park. Seeing the transformation that has taken place in the Lower Lea Valley is nothing short of astounding, and this area will be a great legacy for the people of London and the UK.
'The fast pace of development is no doubt down to the great spirit of cooperation that exists between the different partners involved in the 2012 project. Their ability to work as a team, plan ahead and solve issues together is ensuring that the Games and legacy planning remain on track as we head towards 2012.'
Oswald also praised the attention being paid to ensure value-for-money and a first-class experience for everyone coming to the Games in 2012.
