Costs of building roads reviewed

Summary

‘Estimating and Monitoring the Costs of Building Roads in England’ (HC 426) is a Report from the House of Commons Committee of Public Accounts looking at Department for Transport / Highways Agency expenditure on the development of new roads.

The Department for Transport has approved expenditure of over £11 billion between 1998 and 2021 for the development of new and existing trunk roads and motorways by the Highways Agency, and just under £1.7 billion on major road schemes proposed and developed by local authorities in five year Local Transport Plans.

Following on from a National Audit Office report on this topic also entitled 'Estimating and Monitoring the Costs of Building Roads in England ' (HC 321 2006-07) published in March 2007, the Committee's report examines the steps taken by the Department for Transport and the Highways Agency to improve value for money and oversight of the roads programme and contracting methods and project management capability.

By September 2006, the Agency's 36 completed schemes in the Targeted Programme of Improvement cost 40 per cent more than estimated initially, and for schemes still to be completed, latest forecasts indicate that final costs could be 27 per cent more than original estimates. The main causes for costs exceeding estimates are increases in construction costs, higher than forecast land prices and compensation to landowners, inflation and changes in the scope of the project.

The Report finds that the DfT has not been rigorous enough in its oversight of the Agency's delivery of major road schemes, allowing it too much latitude on delivery and cost plans, and has failed to monitor in-year expenditure against progress and delivery milestones. The Agency is overly reliant on consultants for project management expertise and needs to develop its in-house capability.
