HS2 Works Notification: Preparing the Tunnel Boring Machine

We are writing to let you know about some planned works in your local area.  

Recently, we told you about our works to build the Tunnel Boring Machines (TBMs) at our West Ruislip site. We will use the TBMs to build the railway tunnels between West Ruislip and Greenpark Way in Ealing.

The TBMs have now been assembled and on Tuesday 30 or Wednesday 31 August 2022, one of them will be switched on and will cut up to one metre into the concrete wall ahead of it. This is preparatory work before we launch the TBMs.

Once launched, they will run 24 hours a day until they reach Greenpark Way. We will let you know the launch date as soon as it is confirmed.

We would like to apologise in advance 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.

What to expect

During this preparatory activity, there will be no soil extracted from the machine and the conveyor will not be operational.

We anticipate that any noise and vibration will be minimal given that the TBM is situated approximately 10 metres below the surrounding ground level.  The expected duration of this activity is approximately one hour, during our core working hours of 8am to 6pm.

Members of our engagement team will be present on The Greenway between 10.00am and 12.00pm and again from 2.00pm to 4.00pm on the day to answer any questions that you may have.

We will only carry out activities agreed with the London Borough of Hillingdon and will adhere to the agreed working hours and noise and vibration limits. You may notice different types of noise during these works.

We would like to apologise in advance 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.https://www.hs2.org.uk/work-items/preparing-the-tunnel-boring-machine/
