UK6 - Contract Award Notice
Summary of the contracting process

National Highways Limited commissioned independent checking and safety assessment for its Tunnel Control and Management System (TCMS), initially being deployed at Hindhead Tunnel. The work covers Category 3 checking of design and test documents, independent functional safety assessment of the system’s design and implementation, and support to complete the fault-free running and trial periods and safety case needed for final certification. It also includes Approval in Principle for Southwick and Roundhill tunnels, supporting planned refurbishment schemes and their progression to detailed design. The requirement is for specialist tunnel engineering and safety assurance services, rather than construction or supply of tunnel equipment. The named delivery country is the United Kingdom; specific delivery locations are Hindhead, Southwick and Roundhill tunnels.

The procurement is complete and the contract was awarded to ATKINSRÉALIS UK LIMITED on 17 August 2026. The award followed a competitive process run through a selective procedure, with the contract awarded under a framework. The contract was signed on 15 September 2026 and runs from 15 September 2026 to 13 September 2027. Its stated value is £553,144.52 excluding VAT, or £663,773.42 including VAT. There was one lot, covering the TCMS third-party checking requirement. The published description identifies compliance with CG300 technical approval of highway structures and CD352 design of road tunnels as requirements, and describes Category 3 checking and functional safety assessment as the required activities. No separate scoring or weighting for evaluation is stated in the procurement details.

For suppliers considering similar National Highways work, the award demonstrates demand for independent assurance expertise across tunnel systems, safety assessment and tunnel refurbishment approvals. A credible competitor would need to carry out Category 3 design checking and assess functional safety through both design and implementation, including the supporting evidence needed for certification and safety cases. Experience with highway structures and road tunnel design standards CG300 and CD352 is directly relevant. The scope also favours suppliers able to review and update design and test documentation, support system testing and trial stages, and advise on Approval in Principle for refurbishment schemes as they move towards detailed design. This is a specialist, multi-part technical services requirement, requiring the capacity to cover live system assurance alongside work on more than one tunnel.

Notice Information

Notice Title

TCMS 3rd Party Checker

Notice Description

National Highways is in the process of delivering the new Tunnel Control and Management System (TCMS) for the first phase of the systems deployment at Hindhead Tunnel. Hindhead is the first tunnel from National Highways portfolio of 11 tunnels to be migrated onto the new TCMS. The TCMS is classed as a Tunnel System and as such it's design and development is required to comply with CG300 technical approval of highways structure and CD352 Design of road tunnels. To satisfy the standards, National Highways require an independent design checker to undertake Category 3 Checking and an independent functional safety assessor to undertake functional safety assessments of the design and implementation of the TCMS. The TCMS has completed the majority of the design and test phases and now requires completion of the fault free running period, trial period and safety case which will allow issue of the final certification. There are changes required to several design and test documents which require completion of the Category 3 Checking before issue of the design certification. National Highways are also seeking Approval in Principles (AiP) for both Southwick and Roundhill Tunnels. These AiP's are necessary to progress the approvals of planned tunnel refurbishment schemes at the tunnels in compliance with CG300 and CD352 and to move the schemes into detailed design for the tunnel refurbishments.
