Update: 24/7 works at Mandeville Road Vent Shaft site

What we are doing

What we are doing – 24 hour works update
We wrote to you in April 2023 to let you know that we would be increasing the working hours at our Mandeville Road site to 24 hours a day, seven days a week. The 24/7 works started in April 2023, and we expect them to be completed in May 2024 ready for works to build the HS2 London Tunnels.

We are expecting the Tunnel Boring Machines (TBMs) tunnelling from West Ruislip to Greenford to pass through your local area in Summer 2024. We will let you know in advance of the TBMs passing through your local area.

As we build the HS2 London Tunnels through Mandeville Road Vent Shaft, there will be a short additional phase of 24/7 works needed to carry out underground works to build a tunnel adit (a horizontal passage below ground). This short phase is expected to take place for up to one month during summer 2024. The dates for these works depend on the progress of the TBMs. We will write to you in May when the details of this short phase of works are confirmed.

We would like to apologise for any disruption or inconvenience this may cause. Every effort is being taken to ensure that these works are carried out in the least impactful way. We will ensure that disruption is kept to a minimum and that regular updates are provided.
