Balfour Beatty announced that it has been awarded a £154 million contract to carry out the full transformation works to the London 2012 Olympic Stadium for its operator, E20 Stadium LLP, a joint venture between the London Legacy Development Corporation and Newham Council. This new contract encompasses the £41 million Stadium roof contract Balfour Beatty was awarded in the summer. Balfour Beatty will lead the transformation of the Stadium into an all-round multi-use venue, delivering a lasting sporting, cultural and commercial legacy in East London.

The new venue will host five matches during the Rugby World Cup 2015 and will be the permanent home of West Ham United Football Club from 2016. The venue will also become the new national competition Stadium for athletics in the UK as well as hosting elite international athletics events and other sporting, cultural and community events. A new community athletics track will also be provided next to the main Stadium.

Sustainable construction methods will include features of the existing facility being recycled and incorporated into the new Stadium and the re-use of crushed demolition material, existing balustrades and sanitary ware. At construction peak the project will employ up to 400 people. Balfour Beatty will work with WorkPlace, Newham Council's employment service, to ensure the employment of local people where possible.

Balfour Beatty has also committed to create apprenticeships which will amount to 7% of the total workforce.
