The Olympic Delivery Authority (ODA) has put the tendering process for 2,000 Olympic contracts online.

The e-tendering website, which was launched this week, will allow companies to tender for work online and give them advance notice of contracts.

Main venue contractors will also be able to advertise supply chain contracts through the site. These will range from sports venue design and landscaping to providing occupational health and logistical support for construction projects.

Among the first tenders to go live, before the end of March, will be the construction of the aquatics centre and velopark.
