Preparations for the London 2012 Olympic and Paralympic Games : Progress Report, Department for Culture, Media and Sport

The Olympic Delivery Authority remains on course to deliver its work on the Olympic Park on time, within budget and to the standard required.

On current projections, however, almost the whole of the GBP9.298 billion Public Sector Funding Package for the 2012 Games is likely to be required, with little scope for further unforeseen costs to emerge in the eight months left.

The construction project was 91.9 per cent complete at the end of September 2011, against a target of 92.5 per cent.

Fourteen of the 26 construction projects have been completed and handed over and the remaining projects are on course.

The Olympic Delivery Authority has also either completed, or is on course to complete, its transport infrastructure projects, such as increasing capacity on the Docklands Light Railway.

However, detailed work by the delivery bodies has identified significant challenges.

The likely cost of venue security for the taxpayer, for one, has nearly doubled: the latest estimate is GBP553 million, an increase of GBP271 million.

The London Organising Committee, LOCOG, had estimated that it would need 10,000 security guards.

The current estimate is for as many as 23,700. In transport planning, there have been delays to the full integration of some elements of the transport programme.

Until this is completed, it will not be possible to inform local authorities, businesses and individuals of the full impact of the Games on transport in London.

It will also be years before the value for money of legacy projects, a key element of London's bid, can be fully assessed
