## Summary

Cardiff Council has concluded an open procurement process to award a contract for the "Queensgate Tunnel - Design, Supply, Installation and Maintenance" project. This initiative involves the management of the tunnel's mechanical and electrical infrastructure and related services, under the supervision of Cardiff Council, a public authority classified under Welsh devolved regulations. The procurement process, completed on 18th November 2025, includes a potential renewal option and covers a contract period from 1st January 2026 to 31st December 2028, with a possible extension until 31st January 2029. The award, valued at £5,000,000, with a gross amount of £6,000,000, encompasses services in the construction and maintenance sectors, including tunnel operation and lighting, primarily based in Cardiff, UK (UKL region). Key dates related to the awarding and signatures were scheduled shortly after the conclusion of the award process in November 2025. The selected supplier, SICE, a large-scale enterprise located in Reading, UK, will be responsible for delivering the services specified in the tender.

This tender offers significant business growth opportunities, particularly for companies with expertise in construction and maintenance of public infrastructure, as well as those involved in the manufacture and installation of electrical equipment and machinery. Companies that specialise in the operation and management of tunnel services, including lighting and mechanical systems, would find this tender particularly relevant. Additionally, businesses able to provide innovative solutions for mechanical and electrical equipment in large-scale infrastructure projects, as well as those with experience working with local government contracts, would be well-suited to compete in similar tenders. The procurement method was open, which encourages participation from a broad array of suppliers, enhancing competitive bidding opportunities.
