Crossrail was procured using best procurement practice employed on the London 2012 Olympic and Paralympic Games. This methodology was further developed at Crossrail into the ‘six pillars model’ and was adopted by Infrastructure UK (IUK), forming the basis of a procurement module in the Project Initiation Route-map. Much of the Crossrail procurement learning legacy is incorporated in the procurement module which provides helpful guidance when initiating procurement on major programmes in the UK.
