From w/c 31 January 2022 onwards, the Eltham site team will be working a 24/5 shift pattern on weekdays, with an option to work on Saturdays till 1pm over a 6-week period.

This is due to difficult ground conditions that the team have encountered during their ongoing shaft works, leading to a change in construction methodology which requires continuous work to avoid risks of collapse and for the adjacent railway.

To minimise any disruption and impact, the team will be operating a crane to empty skips of muck from the shaft and noise barriers will be used. During night shifts, construction activities will be mainly restricted to below ground activities, and only a limited amount of plant operations will be required at surface level in order to stockpile spoil from excavation. The Eltham team have also taken the following actions:

  • Putting in place dampers to try to eliminate the noise from the self-tipping skip which is used to dispose of the muck evacuated from the shaft.

  • Reducing muck skipping activities where possible.

  • Educating operatives working on night shifts to keep noise level to the minimum and be considerate of neighbours.

  • Avoid any extreme acceleration of the crawler crane.

There will be vehicle movements for staff at the shift handovers, however unless an emergency occurs, the gate will be locked at 9pm for the duration of the night shift and there will be no lorry movements after 9pm.





Our site at Eltham is located on Rochester Way, north of Falconwood railway station. 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 are 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.

Our application to the Royal Borough of Greenwich 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 milestones achieved at Eltham:

  • Held public information events in 2018 about the shaft and headhouse
  • Application to build a headhouse at our site in Eltham was approved by the Royal Borough of Greenwich Council in February 2019.
  • Completed building the temporary haul road from Welling Way, across Falconwood Field, in September 2021. The new haul road will help avoid disruption to local residential roads.

Working Hours:

  • Our usual working hours at Eltham are 8am - 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.

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.
  • 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.


  • 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.
