UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

National Highways commissioned gantry aerodynamic wind tunnel testing for the Lower Thames Crossing, a new road linking Essex and Kent through a tunnel beneath the River Thames. The requirement covers specialist aerodynamic testing facilities, computational analysis and subject-matter expertise to assess virtual and physical structural performance and replicate aerodynamic behaviour relevant to the strategic road network. This is a technical analysis, inspection and testing service (CPV 71621000, 71630000 and 71632000). The work is associated with the Lower Thames Crossing project and delivery is within the United Kingdom. National Highways is the public-sector buyer. The procurement was for a single supplier and one complete lot, assessed as suitable for small and medium-sized enterprises.

The procurement is complete and was awarded to Ramboll UK Ltd. The award was dated 11 March 2026 and the contract was signed on 8 July 2026. The awarded value is £325,071 excluding VAT, or £390,085 including VAT. The contract period runs from 8 July 2026 to 31 March 2027, with an option to extend for up to 12 months, to 31 March 2028. It used an open procedure, with submissions due by 8 December 2025 at noon and enquiries closing on 24 November 2025 at noon. Evaluation weighted technical quality at 70% and commercial price at 30%. Three bids reached the final stage, including two from SMEs. The contract is active.

This award indicates demand for specialist aerodynamic engineering and testing capability within a major strategic-road infrastructure programme. A credible future supplier would need access to physical wind-tunnel testing facilities, computational analysis capability and expertise in structural performance and aerodynamic behaviour. Experience translating test results into practical assessments for gantries or comparable road infrastructure would be relevant, alongside the capacity to deliver both virtual and physical testing and the subject-matter advice needed by a major highways client. The requirement was technically led: quality carried more weight than price in evaluation. The successful supplier was a large organisation, but the opportunity was identified as suitable for SMEs, suggesting that smaller specialist consultancies or testing providers with the necessary facilities and technical partnerships could compete.
