What we are doing

Tunnel construction from West Ruislip to Greenford completed in March and we are carrying out 24/7 works to remove tunnelling support structures inside and outside the tunnels. Please follow this link to the programme of the demobilisation works at West Ruislip published in May 2025.

Update: West Ruislip Portal demobilisation works – July 2025

We would like to update you on the works programme as the demobilisation progresses throughout the next few months until January 2026.

The removal of conveyor structures for the downline tunnel were completed and works are now underway to remove tunnelling support structures inside and outside the tunnels for the upline tunnel.

The demobilisation and removal works will be carried out for the following:

• The conveyor structure
• The launch chamber entrance
• Grout plant removal
• Cooling plant and workshop removal
• Tunnelling support structures removal

We will only carry out activities agreed with the London Borough of Hillingdon and will adhere to the agreed working hours, noise and vibration limits. We continue to monitor noise, dust and vibration throughout our works to ensure we have measures in place to minimise disruption.
