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.
