Sheet piling works in West Ruislip from 19 October for three weeks
Sheet piling works will begin at the West Ruislip site on 19 October. The works are expected to last three weeks.

What we are doing
From the week commencing 19 October we will carry out sheet piling works inside the construction site at West Ruislip. This work will help us to install a temporary tank to be used as stormwater drain to prevent flooding in the work area.
Sheet piles will be installed in sequence along the planned excavation perimeter to provide temporary walls within the ground to support our water tank. A mechanical machine will be used to push steel sheets into the ground.

How this work might affect you
A piling rig, cranes and construction machinery will be visible in the area
during these works.
The project team will take every measure to reduce noise impacts, however
you may notice some construction related noise and vibration.
Sheet piles will be pressed into position. In the event that we find hard
ground or obstacles, a vibro-hammer will be used to disturb the ground and
drive the sheets through the hard areas. Should this method be required, it
will be used for approximately one hour per day.

Duration of works
The activity will take place from w/c 19 October for three weeks.
Hours worked will be Monday to Friday 8am to 6pm and 8am to 1pm Saturdays.
We may be on site for an our before the start and/or end of each shift.

What to expect
Delivery and set up of equipment, cranes and piling rigs.
Our piling methods may involve vibrating piles into the ground.

What we will do
Conduct noise and vibration monitoring to ensure works are within project approval limits.
Use water carts to reduce the amount of dust
