Notice of HS2 Utility Works on A40 near Hanger Lane – May to Sept 2024

These works are not in LBH but delays on the A40 near Hanger Lane caused by these Utility works could lead to delays on the A40 back as far as Hillingdon at certain times so this has been  included for information. 

Residents of LBH may remember the disruptive Utility works in LBH that were carried out by HS2/SCS ahead of the tunnelling and led to disruption over lengthy periods on Ickenham Road, West End Road, Bridgwater Road and Station Approach South Ruislip. It is now the turn of LB Ealing to face this issue ahead of the tunnelling in that Borough, and the most disruptive of all works is that to the Gas Main on the A40 near Hanger Lane.

From 06/05 to 30/09 HS2/SCS will have 2 Lanes of this 6 Lane Road closed, so if you can avoid this area it is best to do so.

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). 

Summary below: 

•             Network Rail have now reopened the SCS Rail Siding for the usual 1 Train per Night delivery into West Ruislip Portal

•             The arrival time is as usual (after 11pm, off loading during the night and departing West Ruislip Portal around 7am)

•             SCS hope to be back to full capacity Train deliveries asap (the longer Train carrying 140 Segments each)

•             Both TBMs are now tunnelling once again which means there is a need to keep deliveries both by Rail and Road ongoing at present

•             LBH have agreed in exceptional circumstances (and to enable tunnelling operations to continue) to keep TBM Segment deliveries also coming in by road 24 hours a day 7 days a week until 14/06 at present

•             This will allow the surplus stock to build up and compensate for the smaller number of segments incoming by rail. 

SCS Noise Barrier Testing near Breakspear Road South – 03/06 to 27/10 

•             There will be Noise Barrier testing from early 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 but has a short delay).

•             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.

Forward Planning – Breakspear Rd South – Road Closure under Railway Bridge for Culvert works 

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)

Extended working hours at our site on Breakspear Road South

•           What we are doing

•             From 17 June to 31 December 2024, we will be carrying out work at our site on Breakspear Road South, north of the Chiltern Railway Line, either side of Breakspear Road South.

•             We will be working to construct the three Retained Embankments that connect the West Ruislip Portal, east of our site to the Copthall Tunnel, which is west of our site boundary. The consented extended working hours are, 7am to 7pm Monday to Friday and 7am to 4pm on Saturdays.

•             We will be building the Embankments to required height using machinery for delivery and placement of material and the compaction of placed material, including vibratory rollers.

•             We expect that these works will create some noise; however, we will ensure that the noisy works will not commence before 8am, including the use of ground compaction equipment, and excavator activities.

•             We will only carry out activities agreed with the London Borough of Hillingdon and will adhere to the agreed working hours, noise and vibration limits.

•             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.

3^rd Party works – 2-Way Traffic Lights on Breakspear Road South Sat 27/04 & Sun 28/04

We have been made aware of some 3^rd Party works on behalf of Affinity Water that will require the use of 2-Way Temporary Traffic Lights this weekend on Breakspear Road South near the junction with Tile Kiln Lane. 

The works will be taking place on Sat 27/04 and may also carry on into Sun 28/04 but they will be completed as quickly as possible to minimise any delays.
 

Notice of Extended Hours Working for Concrete Pours at West Ruislip Portal – Final Pour Scheduled for Tue 30/04

HS2/SCS have received consent from LBH to carry out some long continuous concrete pours for the construction of the 2 Attenuation Tanks over extended hours within the West Ruislip Portal Site.

These concrete pours are taking place over 3 different days with the 1^st pour taking place on Tue 09/04 and the 2^nd pour taking place Thur 18/04. After this there is now scheduled to be a final pour on Tue 30/04 but it is not expected to take as long as previously thought so should not require use of all of the extended hours up until midnight. SCS have been granted consent to carry out the pours between 6am and midnight on these dates

My apologies – I got ahead of myself with the previous post. This is what I meant to post – two downloadable (or readable here) pdf files. Lots of HS2 stuff here mostly of immediate interest.

TBM Segment Delivery by Lorry to West Ruislip
 
LBH have received a request from HS2/SCS for up to 24 lorries per day (Mon to Sat) to bring Segments for the TBMs into the West Ruislip Portal by road during the hours of 8am to 10pm.
 
With both TBMs now once again tunnelling at full capacity they seem to be going at a much faster rate than previously thought (tunnelling up to 22 metres per day). When SCS calculated their requirements to keep the TBMs serviced with Segments last year they were working on the assumption that the TBMs would not tunnel more than 15 metres per day, so they would need approx. 700 Segments per week.
 
This was managed with the overnight Rail Deliveries of Segments into West Ruislip Portal, with 5 Trains per week each delivering 140 Segments (equalling the required 700 Segments per week).
 
With the increased speed of the tunnelling SCS now require additional Segments to keep the TBMs running, and as they cannot get any more than 5 Trains per week into West Ruislip due to limitations with capacity with Network Rail, the only solution is to bring in the additional Segments that are required by road. It has also been the case that with Rail Strikes more frequent over the last few months there have been a few occasions where SCS are only getting 3-4 deliveries by Rail per week.
 
The lorries would all use the existing Approved Lorry Route entering West Ruislip Portal (via Swakeleys Roundabout, Swakeleys Road, Ickenham Road) and return using the same route. The majority of these deliveries would be expected to be carried out during Core Working Hours (Mon to Fri 8am to 6pm & Sat 8am to 1pm) but there may be up to 6 lorry deliveries each day that fall outside the Core Hours and would be delivered up to 10pm.
 
LBH have agreed that SCS can trial these deliveries by road now until the end of April, with SCS will carrying out Engagement with residents to advise of the additional lorries delivering the Segments.
 
LBH will continue to review the situation before committing to allow this to be extended until around August 2024 (which is the current requested date). LBH did question the viability of bringing the lorries in along Swakeleys Road, Ickenham Road into the West Ruislip Portal, but were advised that due to maintenance works due to take place on the internal Haul Roads it would not be feasible at the outset to route the lorries via either Harvil Rd Gate 2 or Breakspear Rd South (and along the Haul Roads to the Portal).
 
Please note that there will be no additional lorries over the agreed 550 lorry movements per day around Swakeleys Roundabout with these additional Segment deliveries built into that daily limit. Over the last few months there has been a noticeable drop off in the amount of HS2 lorries delivering to the HS2 Sites in Hillingdon, so these deliveries should not cause any additional impact to our Road Network in the north of the borough.
 
In summary:
 

• SCS Requesting up to 24 Segment lorry deliveries each day during extended hours – 8am to 10pm Mon to Sat
• 24 lorries x 6 days = (144 lorries / 3 segments per lorry = 432 segments)
• In addition to up to 5 Train deliveries per week at Night (140 Segments per Train x 5 nights = 700)
• Total amount of Segments per week = 1132
• Of the 24 lorries per day it would be likely that up to 6 lorries would be delivering outside Core Hours (between 6-10pm)
•  
•  
•  
•  

• Mon 29/07 to Sun 11/08 (2 Weeks during School Summer Holidays)
• Works to upgrade the existing Culvert to improve the drainage in the area
• These works are expected to take up to 2 weeks to complete

 
These works are the last large Road Closure in the HS2 Highways Programme in LBH and have been in the pipeline for over a year now. 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.
