We will need to build a permanent shaft and headhouse at our site at Kings Avenue, in order to drive a tunnel boring machine to our reception site at Wimbledon. The site will also need to receive a tunnel boring machine from our existing substation site at New Cross. Excavated material would also be removed at this site.
Our site on Kings Avenue is located at the junction of Kings Avenue and Acre Lane.
It is our intention to build the tunnels and shafts under our permitted development rights, which means we do not need planning permission for the entire project.
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 have secured planning permission for the headhouse from the London Borough of Lambeth.
The granting of our planning application follows a series of public information events we held at various locations across our route earlier this year, where members of the public found out more about our works and the wider project and gave us some helpful feedback.
- 24-hour working is currently underway at Kings Avenue while we build the tunnel.
- Above ground work will take place from 7am to 5pm Monday to Friday, and 8am to 1pm on Saturdays. During the night our works will largely take place below ground. 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.
- Dimensions: The shaft will be approximately 15m in diameter and 35m in depth. The headhouse will have a maximum footprint of 9.5m long by 6m wide, reaching a maximum height of 4.6m.
- Traffic movements: We anticipate there would be approximately 38 HGV movements per day during peak construction activity, while we build the tunnel.
- Access: Our construction vehicles will leave the site from Acre Lane or Kings Avenue, before joining the A23 and/or A205
- Works started in April 2020 and are due to finish in June 2025.
- The tunnel is scheduled to be built between February 2021 and April 2023.
- The headhouse is scheduled to be built between April 2024 and March 2025.
In light of the current situation regarding coronavirus, we wanted to share a short update with you about the works that are due to take place at our Kings Avenue site.
London Power Tunnels is a key part of the national infrastructure. These are works that need to take place today to ensure the future running of the network. Together with our contractors, we are continuing to progress with the critical elements of the project in line with current Government guidance on construction activity.
As well as work at Kings Avenue, we will also be working at our Hurst and Old Kent Road (New Cross) sites, as these are three sites key to the development of the project. At all sites we have introduced stringent site operating procedures to safeguard our workforce, their colleagues, their families and the UK population.
We will be commencing low-level site clearance work until later in the year, when we will start to ramp up activity at the start as we begin work on tunnelling. We remain committed to open and transparent communications with all our stakeholders on this project and will keep you updated on works at this and other sites.
This section of the website will be kept up to date and our community relations helpline (0800 783 2855) remains open 24/7 to answer any questions. You can also email us at [email protected]
