## Summary

National Highways Limited procured ground investigation works for the A483 northbound and southbound Oswestry–Welsh Border scheme. The requirement covers fieldwork, associated testing and reporting to support development of the road improvement scheme. It is classified as ground investigation services (CPV 71351500), although the procurement category is works. Delivery is in the West Midlands, covering the Oswestry–Welsh Border area. The work involves collecting and testing ground information in the scheme area and producing reports that can inform design, construction planning and engineering decisions. This is a specialist highway-infrastructure investigation requirement rather than general construction, and is relevant to firms providing geotechnical fieldwork, laboratory or in-situ testing, and technical ground investigation reporting for major roads.

The procurement is complete and has been awarded. National Highways used a selective call-off from its Ground Investigation Framework rather than an open tender. The award was made on 4 August 2026 to Tetra Tech Limited for £97,726.82 including the stated GBP currency. The contract period runs from 3 August 2026 to 31 March 2027. The tender submission deadline was 16 July 2026 at 3pm. The award covers the full ground investigation requirement for the A483 Oswestry–Welsh Border scheme. Tetra Tech is the selected supplier and the award is active. The published procurement data identifies the requirement as unsuitable for small and medium-sized enterprises and voluntary, community or social enterprises. The procurement was evaluated through the framework call-off process.

For suppliers that did not win this award, the requirement indicates demand from National Highways for specialist ground investigation supporting strategic road schemes. A credible competitor would need the capability to plan and undertake highway-site field investigations, manage site data and samples, arrange appropriate testing, and produce clear technical reports that support scheme development. Experience of working around live or proposed strategic-road infrastructure would strengthen a future response, alongside robust health, safety, environmental and quality controls. The route to market is a call-off from a Ground Investigation Framework, so relevant firms would need framework access or a suitable position within the applicable supply chain. The successful supplier was a large organisation, indicating that the buyer values capacity to coordinate fieldwork, testing and reporting as one delivery package.
