What is being bought
Published requirement descriptionA two stage tender process, consisting of Request to Participate (R2P) stage and Invitation to Tender Stage (ITT) for the Design & Build of Caerphilly Interchange.
The Caerphilly Interchange Project comprises the procurement of a single Design and Build contractor to deliver the redevelopment of Caerphilly railway station and adjoining bus interchange into a modern, fully integrated multi‑modal transport hub.
