HS2 Works Notification: Traffic light repair on High Road Ickenham

We’re writing to let you know about some planned works that we will be carrying out in your area. 

From 7am on Saturday 1 October to 6pm on Sunday 2 October, we will carry out essential repairs to the traffic lights at the pedestrian crossing opposite the West Ruislip Station entrance.

To ensure these works can be carried out safely, the pedestrian crossing will be closed throughout and the lanes on the High Road will be narrowed.

A temporary pedestrian crossing will be in place on Ickenham Road near the HS2 site compound entrance. The cycle lane and bus stop will be maintained throughout.

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 we are doing
We wrote to you recently to inform you that our newly assembled Tunnel Boring Machine (TBM) at the West Ruislip Portal site would cut up to one metre into the concrete wall ahead of it on Tuesday 30 August.
We are now ready to launch our first TBM this month on its journey towards Greenpark Way (Ealing) which will last until June 2024.

What to expect
From late September 2022 to June 2024, we will be undertaking tunnelling works. We anticipate our second TBM will be launched in late October 2022.
Once launched, the TBM will require the following support activities at the West Ruislip Portal site. You may hear some different noises from our site as a result of these activities, but we will ensure that we adhere to the agreed working hours, noise and vibration limits set by the London Borough of Hillingdon. To minimise noise, acoustic screens and tents will be used.

Tunnel segments
The TBM operates as a self-contained underground factory – digging the tunnel, lining it with concrete wall segments and putting them into place. The segments will initially be delivered by road and stored on site. Two gantry cranes will lift the segments onto the multipurpose service vehicles which will move segments to the TBM. Initially the segments will be delivered to our site during core working hours and we will keep you informed should this change.

Conveyor system
Soil excavated from the tunnel will be used to landscape areas on each side of the Chiltern line railway. The first excavated soil will be transported by a small temporary conveyor to a designated area within the site boundary until December 2022. The temporary conveyor will operate 24/7. We will start constructing the main conveyor and will provide you with further information in due course.

Rail siding
We have started building a rail siding at our site which will enable the delivery of tunnel segments by rail from the end of 2022/early 2023. We will update you on this activity later this year.

We anticipate that any noise and vibration relating to the TBM launch and its progress underground will be minimal given that it is at least 10 metres below the surrounding ground level. This distance is measured from the crown of the tunnel and not the track bed.
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 to ensure that disruption is kept to a minimum.

Engagement
Our engagement team are available to answer your questions about the TBM launch and our works in the following ways:
– Our Community Information Hub at the mouth of our site on Ickenham Road will be open each day from Monday 26 to Friday 30 September from 10am to 4pm Monday to Friday.
– We are also planning a public engagement event locally and invitations will be sent out soon.

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/
