What we are doing
Excavation and Reinforced Concrete Works in Wormwood Scrubs
We previously notified you that we are continuing our work to divert utilities along Old Oak Common Lane by installing eight micro tunnels from the Wormwood Scrubs site up to the main compound. You can find out more about our works, including our works updates here.
We have now excavated the launch and reception chamber to prepare the area to launch and receive the micro-tunnelling machine. As part of this work, we have also installed concrete structures in the chamber to enable the micro-tunnelling to be carried out.
Update on micro-tunnelling works in Wormwood Scrubs
The launch chamber is now complete, and we have installed two of the eight micro-tunnels, which will run from the launch chamber in Wormwood Scrubs site underneath the railway tracks to the reception chamber in the main site. These micro-tunnels will be used to divert the services along Old Oak Common Lane. This diversion is needed to allow us to lower Old Oak Common Lane that is planned in the future.
