## Summary

The procurement process for the "CVL Transformation - Rhymney Valley Line Electrification" contract was conducted by Transport for Wales, a public body located in Pontypridd, United Kingdom (UKL). This procurement involved railway construction works, focusing on the design and construction of the electrification for the Rhymney Valley, Coryton, and Cardiff Bay Lines. The procurement was executed using an open procedure, with an accelerated process justified by a Prior Information Notice issued in July 2022. The procurement stage has reached the award phase, and the contract, with a value of £33,000,000, was signed on 5th April 2023. The project falls under the industry category of railway construction works and is covered by the Government Procurement Agreement (GPA).

This rail electrification tender presents valuable growth opportunities, particularly for large-scale infrastructure businesses with expertise in railway construction and electrification. The contract has been awarded to Seilwaith Amey Cymru / Amey Infrastructure Wales Limited, making them a key player in the project and potentially providing subcontracting opportunities for firms specialising in niche areas such as overhead line equipment installation. Companies with experience in large public infrastructure projects, particularly those capable of operating swiftly within accelerated timelines, would be well-suited to compete and collaborate in this domain. The emphasis on both quality and price in the award criteria means that firms offering innovative solutions and competitive pricing could also find opportunities for future tenders in this sector.
