** Update to works September 2021 – shaft sinking at Eltham **

We have nearly completed building the temporary haul road and from w/c 4 October 2021, we will start the next phase of works on site. This will involve sinking the tunnel shaft to receive the tunnel boring machines (TBMs) from our sites at New Cross and Hurst.

As part of these works, there will be muck away loads (the removal of waste spoil) taken from the site in wagons, as well as deliveries of required materials and equipment to the site.

We will be using the new haul road for all this activity to avoid any disruption to local residential roads.

Our working hours remain as normal during this phase of works.

We will be building a permanent shaft and headhouse at this site in order to receive the tunnel boring machines from our existing substation sites at New Cross and Hurst. The shaft and headhouse will be used for ventilation and as a permanent access route for the tunnel once it is built.

We will be building the tunnels and shafts under our permitted development rights.

There are points along the tunnel route where we need to build headhouses to cover the shafts. Headhouses are required for ventilation and as a permanent point of access for the tunnel once it is built. We are seeking planning permission for these where they are not on our operational land, including at our site on Kings Avenue.

Our application to the Royal Borough of Greenwich Council to build a headhouse at our site in Eltham was approved in February 2019, as well as a temporary access route from Welling Way, across Falconwood Field.

The submission of our planning application followed a series of public information events we held at various locations across our route in 2018, where members of the public found out more about our works and the wider project and gave us some helpful feedback.

Key facts:

  • Dimensions: The shaft will be approximately 15m in diameter and will reach a depth of approximately 40m. The headhouse will have a maximum footprint of 15m by 15m and will reach a maximum height of 10m.
  • Working hours: Our working hours will be from 8am to 6pm Monday to Friday, and 8am to 1pm on Saturdays. There will be no work on Sundays or Bank Holidays. Occasional out of hours work may be necessary and we will keep you informed about this.
  • Traffic movements: We anticipate there will be approximately 16 HGV movements per day during shaft construction, and 4 per week during headhouse construction.
  • Access: Our construction vehicles will use Rochester Way to enter and leave the site, before joining the A2.

Timeline:

  • We plan to start works in February 2022 until August 2027.
  • Shaft construction works are anticipated to take place between July 2021 and February 2022.
  • The headhouse will be built between March 2023 and January 2024.
