## Summary

Transport for Wales has issued a tender for "Earthing and Bonding" works essential for the electrification of the Core Valley Lines, located in Pontypridd, UK. This procurement falls within the works category and was initiated through an open procedure. Key dates include the bid submission deadline, which has been extended to 31 March 2022, with the contract valued at £12 million. The tender is part of a framework agreement intended for urgent works and aims to appoint up to four contractors capable of executing required tasks in compliance with railway safety standards.

This tender presents significant growth opportunities for businesses specialising in electrical and construction services within the transport sector. Large and small to medium enterprises (SMEs) with expertise in rail-related safety systems, bonding, and earthing installations will benefit from this tender. Companies that can demonstrate an ability to deliver high-quality services and compliance with the rigorous safety standards required for live rail environments are particularly well-suited to compete for this contract. Additionally, successful bidders will be expected to contribute to community benefits, aligning with social and environmental objectives set forth by Transport for Wales.

## Notice

This requirement is needed to enable the successful electrification of the Core Valley Lines. E&B will play a key part in ensuring the safety of all personnel working on or near the rail, and of rail service users and customers once the line sections are energised. An effective E&B system will assist in minimising any identified Electromagnetic Compatibility (EMC) issues across an installation. Earthing and Bonding will need to be installed across the route, on all OLE assets, stations, bridges, fences and other metal assets to: - Ensure personal safety for those located on or about the railway, - Provide a safe return path for current in the event of an electrical fault, - Provide a return current path for normal load current; and - Ensure the correct operation of electrical protection systems.
