"description": "TfW is looking to appoint a suitably qualified and competent contractor to undertake complex track works and associated level boarding works at Cardiff Queen Street and Cardiff Bay Stations. The work scope is comprised of various track renewal schemes in the areas of Cardiff Queen Street Station and Cardiff Bay, the primary elements being the remodelling of Cardiff Queen Street and the doubling of the line to Cardiff Bay. The works are naturally linked through their geographical location and through the requirement to deliver the works in a dedicated extended track possession in early 2027. Outside of Cardiff Queen St and Cardiff Bay, there are other remaining track works across CVL (including Pontypridd Station) to be delivered including level boarding sites where design is yet to be completed. A number of these sites are likely to be delivered under this contract once the complexity of works and available access is confirmed post design completion.\nTfW intends to undertake a two stage process under the competitive flexible procedure including a request to participate stage and tender stage. Full details can be found in the Tender Documentation. ",
