Tender Notice
Summary of the contracting process

The Eiffage Kier Joint Venture, as part of HS2 Main Civils Works for Lots C2 & C3, has initiated a tender process to appoint a subcontractor for the installation of Precast Concrete UTX (Under Track Crossing) chamber systems and adjoining ducts within the NC2A section, which ranges from North Chilterns to Aylesbury. This project falls under the 'works' category, with specific classifications in concrete products, excavating work, and partially underground railway works. The procurement is valued at £500,000, and the tender stage is currently active, with submissions closing on 30th June 2026. The project is set in the South East region of the United Kingdom, with the contract period expected to run from 30th September 2026 to 1st March 2027.

This tender offers a significant opportunity for specialised subcontractors in concrete work and civil engineering to secure a position within the expansive HS2 project framework. Businesses proficient in the installation of complex precast structures and duct systems, and those capable of managing extensive excavation and construction activities in compliance with stringent standards, would find this project well-suited to their expertise. Despite its size, the opportunity is not specifically geared towards SMEs or voluntary, community and social enterprises, which suggests that the scope and demand align more closely with established contractors possessing considerable resources and experience in large-scale infrastructure projects.
