HS2 works August onwards

Posted on by

From HS2

Upcoming works
Works are ongoing at our sites at Harvil Road and Newyears Green Lane to build the new bridge over the Chiltern Line railway, the Copthall tunnel and the conveyor system.

From 2 August 2021, we will be carrying out the following activities:

• Piling works for the west portal of the Copthall tunnel
• Installation of the conveyor bridge over Newyears Green Lane
• Installation of support structures (abutments and wingwalls) for the new
bridge over the Chiltern Line railway
• Sheet piling at the MSD buildings off Breakspear Road South

We will continue to monitor noise, dust and vibration throughout our works and ensure that adequate measures are in place to minimise disruption.  Please see the following pages for more information about locations and the works we will be carrying out over the next few months.

1. Piling works for the Copthall tunnel
From 2 August to 18 September 2021, we will be carrying out piling work for the construction of the west portal of the Copthall tunnel.
The west portal pilling will be delivered using Continuous Flight Auger (CFA) techniques. CFA piling is when a continuous auger (hollow stem) is drilled into the ground to the required depth. Once the required depth is achieved, concrete is installed via the piling rig and through the hollow stem auger. The auger is then slowly withdrawn, and reinforced steel cages are installed. This method should not cause any disruption.

2. Road closure for conveyor bridge installation over Newyears Green Lane
From week commencing 2 August 2021, we will lift and install the conveyor bridge over Newyears Green Lane. A temporary road closure will be in place to ensure the installation can be carried out safely.
These works are dependent on weather conditions and we will therefore require two weeks after the start date as contingency to complete them. We anticipate the road closure to be in place for up to five days.  We will provide you updates at HS2inHillingdon.co.uk

3. Support structure installation
From 7 August 2021, we will be constructing the abutments and wingwalls, support structures for the new bridge over the Chiltern Line railway.
An abutment is a substructure unit located at the end of a bridge. Its function is to provide end support for the bridge superstructure. Wingwalls are also located at the ends of a bridge. Their function is to retain and provide support to the abutments.
For safety reasons, some of these works will take place between midnight and 6am, Saturday to Thursday, when trains are not running.

4. Sheet piling at MSD building

From 9 to 27 August 2021, we will be installing sheet piles at the MSD Building located off Breakspear Road South within our site.
Steel sheet piles will be installed in sequence along the planned perimeter and pressed into position. When arranged side by side, the sheet piles form a wall to provide earth support. We will not be expecting any disruption for these works.

Extended working hours within our sites
Works are ongoing at our sites at Harvil Road and Newyears Green Lane to build the new road realignment, the Copthall Tunnels and the conveyor system. Some of these works will need to take place during extended working hours. From 7 July until 31 October 2021, we will be extending our working hours on our sites and will be undertaking work on site from 7am to 6pm, Monday through Saturday. This is an extension of our core working hours of 8am to 6pm Monday to Friday and 8pm to 1pm on Saturdays. 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. We will continue to monitor noise, dust and vibration throughout our works to ensure that we have adequate measures in place to minimise disruption. We appreciate your continued patience while we build HS2

West Ruislip concrete breaking trials

Posted on by

From HS2:

At the West Ruislip site, we will be carrying out a 5-day trial of a machine that breaks down concrete into smaller reusable parts.

If this trial is successful, it will mean that the number of lorry movements required to transport concrete to and from site will be reduced and will remove a significant number of lorries from local roads.

What we are doing
Over the coming months we will be carrying out enabling works in the Harvil Road area. These works will allow us to prepare the area which is required for the temporary storage and treatment of the soil that will be removed from the tunnels, before they are placed in their final location.

Our initial works will include:

  • Setting up security fencing and hoarding
  • Delivery of equipment for the removal of topsoil
  • Vegetation clearance, including brambles and hedgerows
  • Preparation works to secure and divert a section of the U49 footpath around the works area

U46 Footpath Diversion

from HS2

The U46 footpath diversion

We are progressing to a stage in our works where we will be diverting a number of footpaths. These works will facilitate the completion of the internal haul road and help to keep as many vehicles off local roads as possible. Our first diversion is the U46 footpath, the short footpath that runs from the Celandine Way to Breakspear Road South near Oak Farm. The surface of U43 has been improved and extended and it currently progresses south behind the trees and emerges at a marked crossing point in Breakspear Road South. Please see map on link below.

Work item details

What we are doing
From 6 to 20 July 2021, we will be carrying out ground investigation along Ickenham Road and High Road near the West Ruislip train station, in the area shown on the map link below. This will help to inform our design decisions in the area. The ground investigation will involve the use of scanning equipment to identify utilities in the area. We will be excavating trial holes to take measurements and ground samples.

How the surveys might affect you
Due to the location of the utility surveys, footpath diversion will be in place and the cycle path will be closed for the duration of these activities. This is to ensure that the surveys can be carried out safely.
There will be no disruption to your utility services.
