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/

What we are doing
From 30 August 2022 to 5 September 2023, we plan to complete major utility diversion works and realign a section of Harvil Road.

We will be carrying out the main utility works and constructing the new road realignment simultaneously. The works will involve:

Installation of Water Main and communication ducting
Diversion of existing utilities into new utility corridor
Chamber construction (water and communication)
Existing road demolition
Highway & drainage construction
Surfacing, white lining, and street furniture
Site fencing realignment

The overall scheme will be completed in three phases between late August 2022 and early September 2023, with the main construction work taking place within our construction site boundaries on Harvil Road.

How these works might affect you
30 August to 15 October 2022: Installing of water main and communications cabling (BT) on Harvil Road either side of the carriageway opposite the SCS gate 1 site entrance

Four-way traffic lights on Harvil Road, southbound and northbound between oil depot and Shorthill Cottage
We will install a north and southbound priority narrowing lane as a safety measure due to the proximity of services

16 October to 27 November 2022: Installation of the remaining section of the water main in order to complete the connection

Four-way traffic lights on Harvil Road, northbound between Oil depot and Skip Lane
There will be a northbound lane closure on Harvil Road along the section of Skip Lane

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

Extension of utility works on Ickenham Road
Further to our notification of 24 June we will be extending the utility works on Ickenham Road. We wanted to complete these works by 12 August, however, we will need to overrun until 2 September 2022, and the current traffic management will remain in place. Access to businesses will be maintained.

During the final phase of reinstating the central reservation the team have had to slow down for safety reasons and concrete works have had to be postponed to avoid material failure due to the extreme weather.

We apologise for the inconvenience caused by these works and for the extension to them. We are doing what we can to keep disruption to a minimum.

How these works might affect you
In order to carry out these utility works safely:

– a footpath diversion will be in place including a temporary pedestrian crossing either side of the work area
– the cycle path will be closed for the duration of these works
– the West Ruislip bus Stop M will be suspended and temporarily moved to a safe location.
– the West Ruislip bus Stop S will remain open at all times.

Your utility services will not be affected.

A412 Closures August – October

As you may be aware, regrettably there is a need for us to close the A412 overnight for a substantial period to build the viaduct decking across the A412. We now have a finalised set of dates and times with Bucks Council.

We understand that this may inconvenience some residents, businesses and other road users in Harefield that use the A412 between Denham and Maple Cross in the early hours, but for their own safety we cannot allow road users to pass under the girder whilst works are underway.

The road will be closed overnight from 10pm and reopened at 6am the following morning, every day (Mondays to Sundays) from Friday 19 August. Works are scheduled to end, and the road reopen 24 hours a day from 25 October 2022.
