Colne Valley Viaduct – design consultation

HS2, via its contractor ALIGN, has submitted a planning application for the design of the Colne Valley viaduct. The details are available to be viewed on the London Borough of Hillingdon website:

https://planning.hillingdon.gov.uk/OcellaWeb/planningDetails?reference=74320/APP/2019/3187&from=planningSearch

Because of the HS2 Act the council has limited powers but there is a public consultation which ends 6 December and the Council would like your comments, even a simple yes or no to the proposed design.

You can enter your comments on the website using the link above.

As the proposed 3.4 Km viaduct crosses into South Bucks a similar exercise is taking place there.

The Colne Valley’s environment is important to us all; it is a source of drinking water and provides a major recreational area for all our communities. The viaduct with its 52 piers will be highly visible and crosses the Mid Colne Site of Special Scientific Interest (SSSI), Local Wildlife Sites, Broadwater Lake Nature Reserve, River Colne, Long Lake, Korda Lake, Savay Lake, the Grand Union Canal, Harefield No. 2 Lake and a Local Nature Reserve and ancient woodland to the north.

The HS2 Select Committee, during our petitioning at parliament, stated that … the Colne Valley viaduct will be the most significant visible engineering feature of the HS2 Phase One route… It will have international significance and its design should reflect that…

There is an immense amount of detail in the application but many aspects of construction and mitigation will be subject to later applications. The computer-generated images provide highly idealised views but it is very difficult to visualise its overall impact; such structures also deteriorate with weather and vandalism. The questions you may wish to consider are:

  • Do the plans give a good visual representation of how the viaduct will fit in with the local landscape of the Colne Valley?
  • Does the concrete design achieve the aim of having have international significance (i.e. looking architecturally good and aesthetic)?
  • What will the impact be on walkers and other users of the park?
  • How well do you think the design will stand up to the ravages of time?
  • How well will the design resist graffiti and vandalism?

Thank you in advance and please feel free to forward a link to this page:

The more objections the better.

 

Overnight closure of Breakspear Road South Fri 25 Oct

the latest from HS2

Notice of overnight road closure on Breakspear Road South – Friday 25 October 9pm to Saturday 26 October 6am

Posted on Oct 18th 2019 by HS2 in Hillingdon

Following earlier emergency repair works to the road surface on Breakspear Road South near our compound entrance, a further overnight road closure is required to complete a permanent repair.

We understand these works will affect road users and the local community and we apologise for the late notice.

To minimise the impacts to road users the closure is being undertaken during night time hours when traffic is lighter. The road will be fully closed between 9pm on Friday 25 October until 6am on Saturday 26 October. We will remove all traffic management by 6am on Saturday morning.

The same diversion implemented during the previous closures will be in place; you can see a map of the diversion below. Access will be maintained to residential properties. Advance warning signs will be installed as early as possible before works commence. Access only signs will be displayed, with operatives present for the duration of the closure.

More HS2 works and events

from HS2

Handover to main works contractor
We wrote to you in September regarding the closure of West Ruislip golf course. We are currently in the process of handover to our main works contractor, Skanska Costain STRABAG joint venture (SCSJV). Initially there will be very little change in the activity that you will see, however, as we move further into the autumn and then winter months there will be a change in the focus of activity, and an expansion of the works area, which in turn will lead to a change and growth in the hoarding line. We appreciate that all the footpaths and rights of way are important to you and we will endeavour to keep as many footpaths open as we can. Some will need to be diverted to ensure both the safety of the public and to ensure the integrity of the working area. We will inform you of any of the specific footpath closures. These changes will be made very clear on the footpaths and users will be made aware prior to changes being made.

What works will be happening
Over the next three months we will begin to create an internal “haul road” which will allow us to use lorries to move materials east-to-west, north of the Chiltern line in order to reduce the number of larger vehicles on your local roads. To assist us in the creation of the haul road we will build a temporary bridge over the River Pinn. We will remove any top soil from our work areas and store it on the golf course. We will treat and test it, and all soil that can be reused will be used in the new golf course redesign once works are concluded. We will be building a small number of offices within the works area from which a small team of engineers and designers will be supervising all the works activity that will be taking place.

If you have a question about HS2 or our works, please contact our HS2 Help desk team on 08081 434 434 or email hs2enquiries@hs2.org.uk

Duration of works

From now until spring 2020 Working hours: Mondays to Fridays, 8am to 6pm and Saturdays, 8am to 1pm (if required) We may be on site for an hour before the start and/or end of each shift.

What to expect

These works are not expected to be noisy, however we will use noise reducing barriers when required to reduce disruption. Staff and vehicles will be accessing the worksites during the above times. They will be reminded to be mindful of residents at all times

What we will do

Provide timely updates and let you know if these dates change at hs2inhillingdon.co.uk

Other upcoming works in your area
During autumn and winter 2019, SCSJV will also be carrying out further utility surveys along the HS2 route. These surveys will inform the detailed design for the new railway. We will provide further information to residents in areas that will be affected by these surveys. Further information will also be made available at www.hs2inhillingdon.co.uk

From now until late winter there will be no increase to the hoarded area.

Weekday temporary traffic lights – Harvil Road

From HS2

Lane Closure on Harvil Road

From 24 October 2019 for up to four weeks there will be temporary traffic lights on Harvil Road. Their location is just south of Lower Lodge where the existing overhead line crosses Harvil Road. Please see the map on the link below for location. This is to create improved vehicle access from the road into one of the new pylon sites. A set of two-way temporary traffic lights will operate between the 24 October and 15 November 2019 from the hours of 9.30am and 3.30pm (weekdays only). We’ll do our best to keep disruption to a minimum and will re-open the road as soon as the work is complete

HS2 and its (lack of) information

An intrepid team member visited the HS2 event on September 22. Its pre-event billing promised this: See visualisations of the portal structure.

Somewhat underwhelmed, our colleague got a copy of the display boards (download the pdf – 1MB)

Anyone who was expecting to learn details, among other things, of construction noise, operational noise, how the two tunnels will be bored, how construction segments will be brought to site and where they will be stored, how the spoil will be removed, the conveyor belts, the design and visual impact of the entrance, would have been disappointed.

Furthermore, most people’s idea of a visualisation of a tunnel portal would be similar to these….

…. which came as a surprise to HS2 staff.

A footnote from me:

Looking at the main document, I was surprised to see trees in bloom in January:

Even if you use the American date format (why would you?) the picture is still misleading.

Tunnel, power supply and archaeology updates from HS2

This, from HS2:

We will be advertising on Commonplace three events that will be coming up in late September today, with invites going out to the community. The events will allow people to see the plans SCS have for the tunnel portal at West Ruislip and will give other contractors an opportunity to update on other works such as archaeology and the TBM power supply.

The events will take place on:
Saturday 21 September at Harefield Community Centre 11am to 2pm
Monday 23 September at The Barn Hotel 4pm to 7pm
Wednesday 25 September at Ickenham URC 4pm to 7pm
