Harvil Road & Skip Lane works – Night Time Only (7pm to 5am) Mon 10/06 to Mon 24/06

HS2/SCS have requested 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. 

Works Activities:

Snagging works including raising Manhole heights to meet the surface

As-Built Surveys

Drainage works at Skip Lane

Parapet sealing on Bridges Harvil Rd – there are multiple Phases of Traffic Management that will be implemented 1 after another (when 1 is completed they move onto the next): 

All Phases carried out from Mon 10/06 to Mon 24/06 – Night Works only 7pm to 5am 

•             Phase 1 = Southbound Lane Closure under 2-Way Traffic Lights – across Harvil Road Chiltern Line Bridge area

•             Phase 2 = Northbound Lane Closure under 2-Way Traffic Lights – across Harvil Road Chiltern Line Bridge area

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.
