Recommendation 6

To facilitate transparent, honest and constructive public and political engagement with the economic and engineering realities of delivering major infrastructure projects, the Government should establish floors and ceilings for project costs and timescales defining the range within which projects are scheduled for delivery rather than setting single specific targets, which are invariably unhelpful and inaccurate. Any breach of a project’s cost and/or time ceilings should be communicated to the appropriate Select Committee by a formal mechanism, which should trigger intense parliamentary scrutiny to protect the public purse and to support effective project delivery.
