Transport for Wales is looking to appoint a maximum of 10 suppliers to 2 separate lots to provide materials which make up the structural main part steelwork and circular hollow section steel piling of a rail OLE system. The main delivery of these products will be for the Core Valley Lines including City & Penarth Lines (CVL) but may also be on any Wales and Boarders rail network project as appropriate.The materials are required to facilitate the electrification of the CVL. The CVL electrification is required to provide a more efficient and faster rail infrastructure and to support the wider CVL upgrades & enhancements and a new rolling fleet.Suppliers are to be aware that Amey Infrastructure Wales (AIW) may also utilise this framework.
