Higgins outlined the steps during a session of questions from the Greater London Assembly.
The 10 steps are:
Announcing the ODA's programme timetable in July, including target start and completion dates for Games venues
Publication of the ODA procurement strategy for stakeholder consultation in July
The appointment of the full ODA executive team by July
The conclusion of the CPO Inquiry hearings into the acquisition of land for the Olympic Park, with the acquisition led by the London Development Agency and 90 per cent of the land now under public control
The announcement tomorrow (Thursday) by the ODA and LDA of the two key remediation and demolition contractors
The appointment in August of the Delivery Partner, the programme manager for the Olympic Park construction and infrastructure work and the biggest single contract to be let this year
The first phase of community engagement in East London about the new site masterplan, which was announced last week
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
The submission of a new planning application for the Olympic Park site in January next year, following the publication of the new masterplan.
'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,' Higgins told the assembly.
'With the Olympic Games and Paralympic Games there can be no Plan B,' he added. 'The Games will start on 27 July, 2012, and they will start in London, so it is vital that we plan for success.'
