Chief executive David Higgins announces next 10 Olympic milestones to London Assembly.

The Olympic Delivery Authority has set out the next ten milestones in the programme to deliver the venues and infrastructure for the 2012 Olympics.

David Higgins, chief executive, told the London Assembly that the ODA's priority was to get the planning right at this early stage.

He said: "It is by putting the right building blocks in place at the start of the process, by having clarity and certainty through timely decision making that you are best able to bear down on cost and delay. With the Olympic and Paralympic Games there can be no Plan B. The Games will start on 27 July 2012, and they will start in London, so it is vital that we plan for success."

This includes announcing the ODA's programme timetable, publication of the procurement strategy for stakeholder consultation and the appointment of a full ODA executive team by July.

Also on the ‘to do' list will be the appointment in August of the Delivery Partner, the programme manager for the Olympic Park construction and infrastructure work; the publication of the Olympic Transport Plan for consultation in September; the start of the procurement process for the stadium this summer and progress on the procurement of the Aquatics Centre later this year; and, following the publication of the new masterplan, the submission of a new planning application for the Olympic Park site in January next year.

Furthermore, a conclusion will be reached for the CPO Inquiry hearings into the acquisition of land for the Olympic Park.

Higgins said that the announcement tomorrow by the ODA and LDA of the two key remediation and demolition contractors will go ahead.

He added: "In the first six months we have hit our major milestones. It is essential that we maintain this momentum and continue to plan for success."
