The London Development Agency (LDA) is looking for designers for an Olympic velopark.
The velopark will contain state-of-the-art cycling facilities at the Olympic Park site in east London, including a velodrome and a BMX racing track.
The designer for the velopark will be appointed regardless of the outcome of the London 2012 Olympic bid, due on 6 July. Funding for the facility has already been agreed by Sport England, the Lee Valley Regional Park Authority, Transport for London and the LDA.
In addition, the LDA, which is the lead backer of the bid, is looking for an adviser to monitor the environmental impact of all engineering, remediation and demolition work at the site.
London mayor Ken Livingstone said: 'London already has outline planning permission in place for its Olympic Park. This means we would be ready to start work from the moment the International Olympic Committee makes its decision.
'The Olympic Park will not only be world-beating in design, but also respectful of the environment now and for generations after 2012, ' he added.
