What we are doing
What we are doing
We wrote to you in January to let you know about the installation of ground monitoring in the local area. These works have been completed. Our surveying team will be visiting the area regularly to carry out monitoring. The monitoring will not impact you.
Under our current tunnelling programme, the first of our tunnel boring machines (TBMs) will reach the Northolt area by 15 March 2024, and the second TBM is due to arrive by 30 March. In advance of this, we need to fill in two boreholes in the open space behind Wilsmere Drive. We will carry out these works from Monday 4 to Friday 8 March 2023.
A small team of operatives will be excavating shallow trial holes, working with portable plant and handheld tools in the borehole locations. We will place barriers around each borehole which will remain in place until the subcontractor returns on the fourth day to ensure that the hole has been filled in correctly. The ground will be reinstated on completion of our works.
