Notice Information

Notice Title

Piccadilly Line Upgrade WP5 Northfields Stabling Enabling

Notice Description

This procurement seeks approval to undertake a programme of enabling civil works at Northfields Depot to support the introduction of the new 24 Tube Stock (24TS) fleet on the Piccadilly line. The works are essential to ensure the depot infrastructure is compatible with the operational, maintenance, and stabling requirements of the new trains. The 24TS fleet introduces modern train design features, including different vehicle dimensions, access requirements, power systems, and maintenance needs compared to the existing rolling stock. As a result, sections of the depot's roads, access routes, and supporting infrastructure must be modified to safely accommodate the new fleet. The proposed civil works will include adjustments to track alignments, road layouts, and clearances across key areas of the depot (including roads IE to 19E, 9W to 19W, and 4W to 8W), as well as any associated structural and groundworks required to enable safe and efficient train movements and stabling. These works will also facilitate access for maintenance activities and ensure compliance with current safety and operational standards. Without these enabling works, the depot would not be capable of reliably supporting the introduction and operation of the 24TS fleet, which is critical to the Piccadilly line upgrade programme. The works therefore form a key dependency for fleet deployment, improved service capacity, and long-term network reliability.

Planning Information

An EoI was issued via RISQS. Suppliers were shortlisted depending on previous experience of similar works and their capabilities to deliver these works. 20 suppliers were identified and invited to complete an SSQ to further identify their suitability. It is our intention to invite 5/6 suppliers to participate in the ITT stage.
