The Olympic Delivery Authority is conducting a root-and-branch review of the Olympic bid that won London the 2012 Games, according to chairman Jack Lemley.

Lemley and David Higgins are looking at all aspects of the bid, including the Aquatic Centre that was criticised by Olympics Minister Tessa Jowell in November for busting its £75m budget.

Speaking to Building, Lemley said the ODA review would be completed in the summer. He said: "There will be a planning document in the summer and a review of all the processes for the rest of the year. We hope to finalise the masterplan by early next year, with the land acquisition in parallel with that."

The ODA is also looking for a director of construction to spearhead the build programme.

It issued tenders last week for five key posts, including director of transport delivery and finance as well as construction and director of infrastructure and utilities.

The director of construction will be in charge of the procurement, management and delivery of the entire construction programme.

The director of infrastructure will be in charge of all the large utilities.

Construction unions intend to nominate a candidate to the ODA board. Frontrunners include Alan Ritchie, UCATT's general secretary and Barry Campfield, the T&G's assistant general secretary. Les Bayliss, Amicus' assistant general secretary, is also thought to be interested in the position.
