Sheet piling works near Harvil Road. Duration of works 7th February 2022 – 31st March 2022
Construction of platforms for piling and sheet piling works Last year we began construction of the Colne Valley Viaduct. To build the 45 piers over land and 11 piers over the lakes we have been undertaking a programme of rotary, vibratory and sheet piling to create strong pier foundations and railway embankments at both ends of the viaduct. In February 2022 we will start earthworks and piling to build the permanent structure which will form the south embankment of the viaduct next to Harvil Road, Hillingdon. When the south embankment is complete it will carry train lines to and from the Colne Valley Viaduct and the Copthall Tunnel approach, via a realigned section of Harvil Road. How may this affect you We will be using a crane and piling rig to vibrate and hammer sheet piles into the ground to create retaining walls around the site of the south embankment and ground piers. These works will start from 7 th February and last until late March 2022. We will only pile in core working hours, from 8am to 6pm Mondays to Fridays, and 8am to 1pm on Saturdays. If you live near the works site, it is likely that the piling activity will produce increased noise which you may hear in your property

Duration of works
7th February 2022 – 31st March 2022 8am to 6pm, Mondays to Fridays, 8am to 1pm on Saturdays Work dates may be subject to change. We will do our best to keep residents updated with any changes What to expect Intermittent noise and vibration from works site during core working hours Some other less noisy works will also take place outside of these hours Plant and machinery visible from Harvil Road and Skip Lane What we will do Monitor noisy works and reduce impacts on local residents wherever possible.

From HS2:

What we are doing
We need to construct a temporary highway to the side of the current Harvil Road to allow us to start work on realigning Harvil Road later this year, and begin to build two over bridges over the Chiltern and HS2 rail lines.

From 13 February we start work to construct the tie-ins to the current highway.

We will need to use construction vehicles in the highway, and to dig a trial hole. To do this safely we need to close the road fully.

How this work might affect you
Harvil Road will be fully closed 24 hours a day from 13 to 21 February inclusive. A diversion will be in place via Moorhall Road / A412 / A40 and will be clearly marked. Access to the Dogs Trust will be maintained throughout the works.

The working hours will run for 24 hours each day to reduce the closure of the road to one week.

What to expect
Harvil Road will be fully closed 24 hours a day We will use lights as needed and we will ensure that these will face the work areas only

What we will do
We will ensure that the diversion is clearly marked throughout. Access to the Dogs Trust will be maintained throughout the road closure. Access will be permitted to the residences north and south of the road closure

HS2 Works Notification:

Update on preparation works for the soil treatment area at Harvil Road

We’re writing to let you know about some planned works that we will be carrying out in your area.

We wrote to you last year to let you know that we would be carrying out enabling works for the construction of the treatment area. As part of these works we will need to extend the security fence and hoarding line to the southern area to continue with the enabling works.

These works will cause no disruption to local residents.

From HS2

We wrote to you in April 2021 to let you know that we would be carrying out sewer investigations near Blenheim Crescent. We need to re-visit this location to carry out additional works that will take place on 28 January 2022. The location of these works is shown on the map overleaf.

We will investigate the condition of the sewer system using a CCTV camera mounted on a small robot. Should we find a blockage, we may need to flush the drainage system using a high-pressure water jet to carry out the investigation.

It may not be possible to carry out the investigation in the works area shown on the map because of proximity to railway lines. As an alternative, we will be able to undertake the investigation via a manhole located nearby just off Aylsham Drive via the car park (see map). https://www.hs2.org.uk/work-items/notice-of-utility-surveys-near-blenheim-crescent-3/

How the surveys might affect you

You may see people working along the railway tracks. We may need to carry out the works via the manhole in the open space next to 259-329 Aylsham Drive. If this is the case, there will be operatives carrying out the survey at this location. Your utility services will not be affected.
