From HS2

Additions to last week’s updates.

We’re writing to let you know about some planned works that we will be carrying out in your area.
HS2 Works Notification: Concrete removal at our site on Harvil Road

From 24 July to 7 August 2024, we will be removing the concrete lining around one of the attenuation ponds within our Southern Sustainable Placement Area site on Harvil Road.
The removal of the concrete will enable access to complete the placement of soil at one of the mounds. The pond will remain in place to support water management on site.

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.

For further information please see our works notification. https://www.hs2.org.uk/work-items/concrete-removal-at-our-site-on-harvil-road/#msdynmkt_trackingcontext=56641887-ef65-47ca-951c-fe89f1056bb4

From HS2

Upcoming – Breakspear Rd South – Road Closure under Railway Bridge for Culvert Trial Holes – Mon 29/07 to Sun 11/08
SCS Mini ‘Pop-Up’ Event in Ickenham 19/07 between 10am and 12pm
SCS Community Event in Ickenham Tue 23/07 between 4pm and 7pm
Extended Hours TBM Segment deliveries by Lorry into West Ruislip Portal – until 31/07
SCS Noise Barrier Testing near Breakspear Road South – June to October 2024
Extended Working Hours at Breakspear Rd South Site for Construction of Retained Embankments – June to Dec 2024

Upcoming – Breakspear Rd South – Road Closure under Railway Bridge for Culvert Trial Holes – Mon 29/07 to Sun 11/08
There has now been a change to the methodology of these works which require HS2/SCS to carry out further Trial Holes in order to finalise their design to replace the Culvert that crosses Breakspear Road South near to the Chiltern Line Bridge.
This means that there will still be the 2 Week Road Closure between 29/07 to 11/08 but this will be to excavate further Trial Holes (rather than replacing the Culvert). Once HS2/SCS are confident on their designs they will present them to LBH to agree a further Road Closure in order to install the replacement Culvert. This means that there will have to be not 1 but 2 Road Closures of Breakspear Road South in order to replace this Culvert which is not good news for residents nor those who use this busy road.
LBH will push for the final Road Closure to be carried out at a quieter time so it is likely that the final Road Closure will coincide with School Holidays (with the anticipated length of the final Road Closure also being 2 weeks).
At present the existing Culvert near the Chiltern Line Bridge does not have the required capacity to take away water run off from the road and as a consequence this area of road is susceptible to flood related issues. The installation of a new Culvert will be able to handle a larger volume of water and should therefore lead to less of a threat of flooding in this area.

Programme of works:

• Mon 29/07 to Sun 11/08 – Full Road Closure for excavating of Trial Holes (2 Weeks during School Summer Holidays)
• TBA – Full Road Closure for Culvert replacement works (2 weeks possibly later in 2024)

SCS Mini ‘Pop-Up’ Event in Ickenham 19/07 between 10am and 12pm

• HS2 SCS will be holding a ‘Pop-Up’ Event at (omitted from notification)
• This mini Event is for residents to come along and discuss Logistics with the SCS Logistics and Engagement Team and will be an informal relaxed session where residents drop by and have a 1-2-1 meeting with HS2/SCS staff.
SCS Community Event in Ickenham Tue 23/07 between 4pm and 7pm
HS2 SCS will be holding a Community Event at Ickenham United Reform Church, Swakeleys Rd, Ickenham, UB10 8BE on Tue 23/07 between 4pm and 7pm where their Project Team will discuss the following areas:

• Copthall Tunnel progress
• Tunnelling in Hillingdon
• Our environmental commitments during construction
• Drone Footage of SCS Sites

This is a Drop-In Event so feel free to attend between 4pm and 7pm

Extended Hours TBM Segment deliveries by Lorry into West Ruislip Portal – until 31/07

Deliveries of TBM Segments by Railway have now resumed following the issue with the Rail Siding recently but due to ongoing issues with HS2/SCS securing any more than 5 slots per week to run Train deliveries, HS2/SCS will continue to transport TBM Segments by Lorry into West Ruislip to maintain TBM operations and build up a surplus of TBM Segments in the Segment Yard.
Recently LBH had allowed HS2/SCS to deliver TBM Segments on lorries into West Ruislip Portal over a 24/7 period, but this has now been scaled back to the initial Extended Hours so these TBM Segments on lorries can now be delivered Mon to Sat between 8am and 10pm. This agreement is in place until 31/07 and will be reviewed again at that time.

SCS Noise Barrier Testing near Breakspear Road South – June to October 2024
There will be Noise Barrier testing from late June to the end of October for 24 hours a day, 7 days a week within the HS2/SCS Site to the west of the entrance off Breakspear Road South (please note this was originally scheduled to start on 28/05). Noise Barrier Testing commenced on 27/06 with the Generator and Actuator Instrument being used 24/7 to test the piles and the ground around them in the 1st Phase of testing.
A temporary embankment has been constructed in the area where Noise Barriers have been installed and the structural integrity will be tested. The scope of the testing is to confirm that the pile foundation and the structure will not have any significant changes due to Trains passing the Noise Barrier.
The anticipated level of noise impact is expected to be minimal and will include the use of a generator which will power the instrument that will simulate the movement of the trains passing (the generator will be covered in acoustic barriers to minimise the noise).
The Trains using the HS2 Railway will not likely stop at night so the 24/7 testing is critical to simulate actual stress and strain on the Noise Barrier similar to the operational requirements and in reducing the duration of the test. This is fundamental to assuring Noise Barrier compliance.

Extended Working Hours at Breakspear Rd South Site for Construction of Retained Embankments – June to Dec 2024

From 17/06 to 31/12 HS2/SCS will be constructing the 3 Retained Embankments which connect West Ruislip Portal to the Copthall Tunnel. To do this HS2/SCS have been consented extended working hours from 7am to 7pm Monday to Friday and 7am to 4pm on Saturdays.
During the construction of the Embankments (that are either side of the River Pinn & Breakspear Rd South HS2 Bridges as shown on the Map below) there is expected to be 10,000 lorry loads of material brought into the Sites from Harvil Rd Gate 2 and across the Internal Haul Roads. Lorries that are unloading on the west side of Breakspear Rd South will exit onto Breakspear Rd South on the HS2 Approved Lorry Route, and lorries unloading on the east side of Breakspear Rd South will continue on the Internal Haul Road to exit at West Ruislip on that HS2 Approved Lorry Route.
HS2/SCS will be building the Embankments to the required height using machinery for delivery and placement of material and the compaction of placed material will be carried out using vibratory rollers.
LBH will be keeping close tabs on the lorry movements and have also not committed to the full duration of the works when signing the consent. At present LBH will keep these works on a trial basis and review them on an ongoing basis.

FROM HS2

Road closure, Utility works / surveys
Estimated Start Date: 29/07/2024. Estimated End Date: 11/08/2024

What we are doing
From 29 July to 11 August 2024, we will be carrying out utility ground investigation works on Breakspear Road South, north and south of the Network Rail bridge.
The installation of a new drainage pipe is needed at Breakspear Road South, therefore we will be excavating a trench across the road to identify the installation site. These works will help to inform our design decisions for the new drainage pipe installation, planned for this autumn.
In order to carry out these works safely, we’ll need to close a section of the road, north and south of the Network Rail bridge, 24 hours a day for two weeks.

How these works will affect you
The ground investigation will be carried out below street level, therefore a road closure will in place to
ensure that the work can be carried out safely.
During the closure, access to residential properties will be maintained, however, there will be no
through access for emergency services.
A clearly signposted diversion route will be in place via Swakeleys Road B467/ High Road B466/
Ickenham Road/ High Street/ Bury Street A4180/ Breakspear Road.
Your utility services will not be affected.
We would like to apologise for any disruption or inconvenience these works 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

Harvil Road & Skip Lane works – Night Time Only (7pm to 5am) Mon 10/06 to Mon 24/06
HS2/SCS are undertaking some Night Time works on Harvil Road and Skip Lane between 7pm and 5am for 2 weeks from Mon 10/06 at 7pm until Mon 24/06 at 5am. There will be Traffic Management on Harvil Road consisting mostly of multiple Phases of 2-Way Traffic Lights and there will be Road Closures in place on Skip Lane. During each day the Traffic Management will be removed so there will be no impacts to users of Harvil Road or Skip Lane between 5am and 7pm each day of these 2 weeks.

Increased TBM Segment deliveries by Lorry into West Ruislip Portal – until 14/06

Deliveries of TBM Segments by Railway have now resumed following the issue with the Rail Siding recently. However, due to Network Rail restrictions on the length of the Train carrying the TBM Segments into West Ruislip Portal, and ongoing issues with HS2/SCS securing more than 5 slots per week to run Train deliveries, HS2/SCS will continue to transport TBM Segments by Lorry into West Ruislip over a 24 hour period 7 days a week currently until 14/06 while they build up a surplus of TBM Segments in the Segment Yard.

As previously advised, while LBH have allowed unrestricted numbers of Lorries carrying TBM Segments over a short-term period the logistical issues faced by the Haulier mean we do not expect to see more than 30 TBM Segment Lorries each day. While LBH have also allowed these deliveries over a 24 hour period 7 days a week timeframe, we do not expect many deliveries to take place outside of the Core Working Hours (Mon to Fri 8am to 6pm & Sat 8am to 1pm).
