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.

 Ickenham Road Lane Closure for 3^rd Party Works – Sun 24/03 at 10pm to Mon 25/03 at 5am
 
I have been informed by the LBH Streetworks Team that they have granted Affinity Water a Permit to undertake works to a water leak on the Bridge on Ickenham Road (between the Tube Station and HS2 West Ruislip Portal Site Entrance).
 
The works will commence on Sun 24/03 at 10pm with a Lane Closure (Eastbound Lane) in place until 5am on Mon 25/03.
 
The Traffic Management should be clear in time for Monday morning rush hour as long as everything goes to plan (Map below showing location of works on Ickenham Road):

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.

What we are doing

The Colne Valley Viaduct crossed Moorhall Road in August this year. We now need to install some safety railing on either side of the viaduct. To ensure this work is done safely we will need to close Moorhall Road at the location of the viaduct, between the River Garden Public House and the junction with Link Way and Savay Lane. Access will be maintained for residents. The public footpath will remain open with some minor diversions.

The closure is early in the morning of Wednesday 3 January 2024 between 1am and 5am.

Ickenham Rd (West Ruislip Tube Station) – Emergency Affinity Water works

LBH were informed on Thur 23/11 that Affinity Water believe there is a water leak under Ickenham Rd near to the Tube Station that requires Emergency works to repair the leak. Overnight from Thur 23/11 (10pm) into Fri 24/11 (6am) Affinity Water closed off the Westbound Lane on Ickenham Rd and put temporary 4-Way Traffic Lights in place so they could excavate into the carriageway on the Tube Station side of the road to try and trace the leak.

The temporary Traffic Lights were removed by 6am on Fri 24/11 and traffic is flowing as normal but Affinity Water plan to return on Fri night 24/11 (from 10pm) and reinstate the carriageway overnight into Sat 25/11 using the same temporary 4-Way Traffic Lights. They hope to have completed the works by 6am on Sat 25/11 and then traffic flow should return to normal.

The leak now appears to have been traced to be on the Eastbound carriageway so Affinity Water will have to approach LBH to agree how they tackle the repair while causing as little disruption as possible. If the location of the leak is near to the Footway then a Narrow Lane Traffic Management setup may be utilised to maintain the flow of traffic but if the location is further into the carriageway then further temporary Traffic Lights might be required (with the works being carried out at night).

As always LBH Officers will try to mitigate the effects on the Road Network as best as possible to keep any impacts on traffic to a minimum.
Breakspear Rd South Night Time Lane Closure – Mon 27/11 from 10pm until 5am on Tue 28/11

LBH have provided consent for HS2/SCS to carry out some surveying of a Thames Water Foul Sewer Manhole which will require a Lane Closure of Breakspear Rd South at Night on Mon 27/11 from 10pm until 5am on Tue 28/11.

Details of works:

Night Time Lane Closure on Breakspear Rd South – Mon 27/11 from 10pm until 5am on Tue 28/11:

• The Lane Closure will be on the Southbound carriageway and there will be Traffic Lights in place to control the traffic flow
• 3-Way Traffic Lights with Heads on Northbound, Southbound and at HS2 Haul Rd Crossing
• Haul Rd Crossing Lights on demand – as outside of Core Working Hours very little HS2 traffic crossing Haul Rd expected

Reason for Works:

• Internal survey of Thames Water Foul sewer manhole involving confined space man entry
