Search to Find World Class Team to Deliver A303 Upgrade Near Stonehenge
Written by Amy

Highways England has launched its search to find potential contractors for the A303 Amesbury to Berwick Down scheme past Stonehenge.

The company, responsible for the country’s major A roads and motorways, has published its contract notice in the Official Journal of the European Union (OJEU), marking the start of an 18-month procurement process.

Highways England’s proposed upgrade of the A303 between Amesbury and Berwick Down includes:

  • eight miles of free-flowing, high-quality dual carriageway
  • a tunnel at least two miles long underneath the World Heritage Site, closely following the existing A303 route, but a further 50 metres away from the Stonehenge monument, avoiding important archaeological sites, and avoiding intrusion on the view of the setting sun from the stones during the winter solstice
  • a new bypass to the north of the village of Winterbourne Stoke
  • junctions with the A345 and A360 either side of the World Heritage Site

And today marks the start of the process to select a world class team of contractors and tunnel specialists to build the best solution for the A303 Stonehenge scheme should planning consent be granted.

Highways England Project Director Derek Parody said: “We expect this scheme to be of interest to some of the world’s best construction companies, who want to be part of delivering this transformational project – a scheme which will not only unlock congestion along this vital A303 route, conserve and enhance the Outstanding Universal Value of the World Heritage Site but also benefit the local and regional economy by providing skills and job opportunities for businesses large and small.

“This in no way pre-empts the outcome of the ongoing Development Consent Order Examination. While this continues to progress, we need to begin the procurement to put us in a position to be able to start construction on schedule in 2021, providing consent is given.

“The start of the procurement process demonstrates the Government’s continued commitment to this scheme and an expectation that progress on it continues as planned.”

The OJEU contract notice covers the £1.25 billion main works contract for the construction of the tunnel’s civil, structural, mechanical, electrical and technology components, including the tunnel boring machine, along with the approach roadworks and structures and the environmental components of the scheme.

The procurement model is through competitive dialogue allowing a period of design development and dialogue during the tender phase when solutions are developed and tested for compliance with DCO requirements prior to awarding a contract.

The approach allows greater flexibility with the appointed team able to hit the ground running once the contract is awarded.

Contracts for enabling preliminary work will be procured separately, as part of the total £1.7 billion capital cost of the scheme.
