Railway Systems - Cross-passage doors

Tender description

This procurement contract includes without limitation the design, development, testing, manufacture, supply, delivery, installation, testing and commissioning of approximately between 350 and 400 cross-passage, fire-rated doorsets, at cross-passages and access/egress points in HS2's railway tunnels within Phase 1 and Phase 2a. Of the provisional total, approximately 350 doorsets are required at cross passages and access points in longer, bored tunnels, with typically two doorsets per cross passage. Approximately 25 doorsets are required in the shorter 'cut-and-cover' tunnels where there is a narrow dividing wall. The supplier will be required - by certain milestone dates in the contract - to produce evidence of a fully compliant, tested and assured system of products prior to commencing manufacture, delivery and installation of the products. HS2 Ltd will reserve certain rights (including the right to terminate or omit work from the contract) in the event that the supplier fails to meet the required conditions by the relevant milestones. Full details will be set out in the tender documentation issued to shortlisted tenderers at ITT stage. It is intended the cross-passage doors contract will be novated to HS2 Ltd's Tunnel and Lineside M&E (including ventilation) contractor once that contractor has been appointed by HS2 Ltd. The Tunnel and Lineside M&E contractor will become the purchaser under this contract and the supplier is likely to be required to provide a collateral warranty in favour of HS2 Ltd and potentially other stakeholders. The manufacturing is intended to commence in time for Phase 1 delivery and installation to take place between 2023 and 2025 prior to HS2 service testing and entering revenue service in 2026. Phase 2a delivery and installation is likely to take place between 2024 and 2026 prior to HS2 service testing and entering revenue service in 2026. These dates are indicative and subject to change. The contract will include the requirement to demonstrate and achieve reliability, take due consideration of the challenging pressure and operating environment of HS2 (to be experienced in tunnels) and provide an optimum solution for the given constraints through design and testing such that the cross-passage door system is developed to withstand the predicted HS2 pressure and operating environment for the duration of HS2's desired service life. Further details are provided in the PQP documentation.
