From the 23 August 2021, we will be:

  • Creating accesses from Windsor Road. This will include traffic management and vegetation removal.
  • Doing environmental mitigation works.
  • Installing a replacement bridge at the eastern end of the Common.

You’re likely to see equipment, vehicles and materials being brought onto the Common.

Once the protected birds have finished nesting, estimated to be in late September, we’ll start installation works. This will include:

  • Diverting paths and continuing to remove vegetation from the working areas.
  • Improving the access roads. To do this a rolling 100m long working area will be fenced off while improvement works take place. This will include laying stone.
  • Fencing the working areas and undertaking the trenchless installation sections.

About installation

Before installation starts, the first thing you will see is signs notifying common users that works will be taking place.

When installation starts, Heras-type fencing bolted together, or strong-wall fencing, will be used to secure the working area.

You may also see mobile welfare units, equipment, materials and vehicles within the working area.

During the open cut installation process, you may see deliveries of the steel pipes. These will be brought to site in a ‘just-in-time’ delivery sequencing – this is because we want to reduce the space needed for the compound within the common. We will also have 24-hour security of the working areas within the common.

Some Public Rights of Way will be diverted. Information on these will be included on our website, once all permits have been obtained. Advance notices will be displayed before paths are diverted or closed, and all diversions will be clearly signposted.

The car parks serving Chobham Common will remain open throughout installation.

We will be using an open cut technique to install through most of the Common. This work will likely take place in October and November 2022.

Chobham Common is a Special Protection Area (SPA), featuring birds protected under European regulations that cannot be disturbed during nesting periods. This means we can only work in the area through the winter months, so we have adapted our timeline to work around the nesting season.

Due to this seasonal restraint, installation work can only take place in autumn and Winter. In order to ensure we can construct within the seasonal constraints; we will be undertaking trenchless works from October 2021 to February 2022. We will then return to install the open-cut sections from October 2022 to February 2023.

Fencing material will be selected to reduce the visual impact on the Common, maintaining low visibility of the working area.

We will be using a Horizontal Directional Drill (HDD) trenchless technique to install in specific areas within Chobham Common.

The work areas will be fully secure with locked gates and 24-hour security.

Vegetation

Where the topsoil has been stripped and stored, this will then be replaced after the works and left to naturally regenerate as agreed with Surrey Wildlife Trust and Natural England.

The vegetation reinstatement will be subject to a five-year aftercare.
