The project, titled "Core Valley Lines (CVL) Transformation: Complex track works with associated level boarding works," falls under the railway construction industry category. Primarily based in Cardiff, the tender involved various locations, including Cardiff Queen Street and Cardiff Bay, aiming for extensive track remodelling work. The procurement method used is a selective competitive flexible procedure. One of the key completion phases occurred with the award stage being confirmed on 28th May 2026, following an active procurement period that started from a tender stage in late 2025. This tender offers significant opportunities for businesses in the civil engineering and construction sector, particularly those with expertise in railway infrastructure. The focus on complex track works and level boarding increases demand for contractors with specialised capabilities in these areas. Large enterprises, like the awarded supplier Amey Infrastructure Wales, are well-positioned to cater to such comprehensive projects, yet smaller, sufficiently qualified businesses could benefit from subcontracting opportunities. This can foster long-term growth through the establishment of local partnerships and participation in future infrastructure developments within the region, aiding in the expansion of business footprints under large infrastructure frameworks. ## Notice Contract details for notice for the Core Valley Lines (CVL) Transformation: Complex track works with associated level boarding works ### Lot Information Lot 1 Options: Options: Level Boarding works CVL Non-complex track works Pontypridd Station works Renewal: Compensation events under the contract ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/050969-2026 | | Notice type | UK10 - Contract Change Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Selective | | Procurement method details | Competitive flexible procedure | | Tender suitability | Not specified | | Awardee scale | Large | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 29 May 2026 | | Submission deadline | 8 Oct 2025 | | Future notice date | Not specified | | Award date | 21 Jan 2026 | | Contract period | 12 Apr 2026 - 31 Aug 2027 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £9,800,000 | | Lots value | £9,800,000 | | Awards value | £5,826,400 | | Contracts value | £9,800,000 | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Active | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | TRANSPORT FOR WALES | | Locality | PONTYPRIDD | | Post town | Cardiff | | Postcode | CF37 4TH | | Country | Wales | | ITL 1 | TLL Wales | | ITL 2 | TLL5 South East Wales | | ITL 3 | TLL51 Central Valleys and Bridgend | | Local authority | Rhondda Cynon Taf | | Electoral ward | Pontypridd Town | | Westminster constituency | Pontypridd | | Delivery location | TLL22 Cardiff and Vale of Glamorgan | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | AMEY INFRASTRUCTURE WALES (AIW | ## CPV Codes ### Divisions - 34 - Transport equipment and auxiliary products to transportation - 45 - Construction work ### Codes - 34946000 - Railway-track construction materials and supplies - 45200000 - Works for complete or part construction and civil engineering work - 45234100 - Railway construction works ## Release History - 29 May 2026 at 14:55 - ContractAmendment - UK10 - Contract Change Notice - https://www.find-tender.service.gov.uk/Notice/050969-2026 - 28 May 2026 at 15:18 - Award - UK7 - Contract Details Notice - https://www.find-tender.service.gov.uk/Notice/050486-2026 - 21 Jan 2026 at 15:01 - Award - UK6 - Contract Award Notice - https://www.find-tender.service.gov.uk/Notice/005383-2026 - 19 Sep 2025 at 13:48 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/058173-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/050969-2026 29th May 2026 - Contract change notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/050486-2026 28th May 2026 - Contract details notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/005383-2026 21st January 2026 - Contract award notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/058173-2025 19th September 2025 - Tender notice on Find a Tender - https://www.sell2wales.gov.wales/Assets/NoticeBuilder_FileDownload.aspx?id=346548 Scope Document - https://www.sell2wales.gov.wales/Assets/NoticeBuilder_FileDownload.aspx?id=346549 Proposed draft form of contract - https://www.sell2wales.gov.wales/Assets/NoticeBuilder_FileDownload.aspx?id=346550 Request to Participate Volume 1 Instructions - https://www.sell2wales.gov.wales/Assets/NoticeBuilder_FileDownload.aspx?id=346551 Request to Participate Volume 2 Questionnaire ## Notice URLs - http://tfw.wales - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
