## Summary

Tees Valley Combined Authority procured independent cost consultancy services for its CRSTS Highways and Active Travel Programme. The work covers reviewing and validating scheme cost estimates, benchmarking, cost assurance and independent advice during project development, Early Contractor Involvement activities and delivery contracts. The requirement is civil engineering consultancy (CPV 71311000), focused on transport schemes, projects and work packages across Tees Valley. The consultancy may also support additional cost reviews, assurance exercises, gateway and business-case reviews, funding assurance, and responses to technical, market, commercial or programme risks. The buying organisation is Tees Valley Combined Authority, based in Darlington. The procurement covered one lot and is relevant to firms providing independent transport infrastructure cost advice and assurance.

The procurement has been completed and the contract was awarded to DE Commercial Services Ltd on 7 September 2026. The award is £120,000 excluding VAT, or £144,000 including VAT. The contract runs from 14 September 2026 to 13 September 2030, with provision for two annual extensions taking the maximum period to 13 September 2032. The procedure was a below-threshold limited competition. Two bids were received, both reaching the final stage; one final-stage bidder was an SME. Evaluation resulted in an active award for the single lot. The scope allows additional services and potential value increases within the overall commission, including further schemes, deeper or additional reviews, changed project complexity and support at programme milestones.

This award demonstrates demand for independent cost consultancy supporting a public transport and active-travel investment programme, including highways schemes moving from development into procurement and delivery. A credible competitor would need demonstrable civil engineering cost consultancy experience, with the ability to validate estimates, benchmark costs against relevant market evidence and provide robust assurance rather than simply prepare prices. Useful capability includes independent challenge of scheme assumptions, commercial and technical risk analysis, review of business cases and funding submissions, and advice during Early Contractor Involvement and delivery-contract preparation. Suppliers should be able to handle changing scheme scope, sequencing and complexity, provide clear advice to funders, auditors and governance bodies, and scale reviews across multiple work packages. The award also shows that an SME can reach the final stage for this requirement.
