Highways Agency, A1 Dishforth to Leeming

The scope of the project is the upgrading of the A1 Trunk Road from Dishforth to Leeming, approximately 21km, in North Yorkshire from a dual carriageway to a dual three lane motorway, including hard shoulders. The project also includes a single carriageway Local Access Road for the majority of the length of the scheme for local and non-motorway traffic, the construction of eleven new bridges, the refurbishment of five existing structures which will span the new motorway and the demolition of six existing bridges. In addition, there are significant associated works such as the demolition of existing properties, the diversion of statutory authority equipment, the installation, testing and commissioning of motorway communications equipment and a five year maintenance period following opening of the new motorway.

Our approach and service delivery can be split into two parts:
Scheme budget management and monthly reporting:

  • Actual costs to date
  • Forecast cost schedule
  • Variance reports (year to date, full year forecast, outturn forecast)

Construction cost management and reporting:

  • Assessment of actual costs
  • Change control (including funding from risk provisions)
  • Risk management support
  • Earned value management
  • Rolling audits of actual cost
  • Review of resourced programme derived cost schedules

We also facilitated, attended and participated in lessons learned workshops to ensure commercial good practice could be transferable.

Contractual matters: significant disputes were avoided by early identification of problems and utilising expertise to mitigate potential impacts and achieve resolution with the contractor.

Accuracy of forecasting: it is vital for the client that annual scheme budget forecasts and anticipated monthly costs are accurate and stable. After early fluctuations and close liaison with the contractor variances against budget were effectively managed and substantially reduced, thus fully meeting the client’s requirements.

Delivery of scheme within agreed budget: by prudent management of risk provisions and monthly commercial management of all individual scheme elements outturn costs were controlled against a background of increasing inflationary pressures and significant levels of construction change.

The new motorway was opened ahead of schedule and was delivered within the client's agreed budget.
