Summary of the contracting process

Transport for Wales is engaging in a major public procurement process for the "Caerphilly Interchange: Design & Build" project, part of the broader South Wales Metro programme. This initiative, valued at a gross amount of £39.6 million, involves the transformation of the Caerphilly railway station and adjacent bus hub into a modern, integrated transport hub. The project is aimed at improving accessibility and commuter experience across the Cardiff Capital Region. The procurement has reached the tender stage, with a selective procedure called the Competitive Flexible Procedure. Key dates include an expression of interest deadline of 26th August 2026, followed by an Invitation to Tender stage in November 2026 for shortlisted suppliers, concluding with a contract award by 15th February 2027. The project supports sustainable travel with a focus on demolition and new construction that supports multiple transport modes.

This tender offers significant business opportunities, particularly for companies in the construction and engineering sectors specialising in transport infrastructure. SMEs are encouraged to participate as the tender process is suited to their involvement. The redevelopment project is expected to stimulate business growth through enhanced transport links and increased footfall to retail and commercial spaces. It is ideal for contractors with expertise in railway station and interchange construction, and firms with proven capabilities in delivering complex, integrated travel solutions. The opportunity allows businesses to contribute to a high-profile regional project with long-term impacts on local transport systems and economic regeneration.
