Summary of the contracting process

The Welsh Government is initiating the procurement process for the "A494 River Dee Bridge Replacement scheme," a critical infrastructure project managed by Mott MacDonald. This tender involves the replacement of a vital bridge connecting North Wales with the north-west of England, addressing its poor structural condition. The procurement process, open as of 29th August 2025, falls under the category of construction work, engineering services, and construction project management services. This competitive flexible procedure is in the tender stage, with key deadlines including an expression of interest by 30th September 2025 and a planned award by 29th May 2026. The project is valued at £145 million, with a gross amount of £174 million, suitable for public authorities in the UK under Welsh devolved regulations, and it is scheduled to commence on 1st June 2026, concluding by 1st March 2030.

This tender presents a substantial opportunity for businesses specializing in construction, engineering, and construction management services, particularly those capable of handling large-scale infrastructure projects. With an open procurement method and the competitive flexible procedure, businesses equipped to address the technical and commercial demands of such a contract are encouraged to participate. SMEs are deemed suitable for this tender, thus expanding participation options. The focus on both quality and cost (70% and 30% weightings, respectively) offers a balanced assessment that can benefit firms with innovative solutions. Companies adhering to NEC4 contracts and those offering sustainable construction practices to meet climate change specifications are particularly well-suited to compete for this contract. The two-stage process allows businesses to initially demonstrate qualifications and later present a full tender, fostering growth opportunities through engagement with a significant government-led infrastructure project.
