Notice of sheet piling works at Breakspear Road South near the River Pinn

What we are doing

We are continuing piling works at our West Ruislip site near the River Pinn until 30 June 2021. These works are required to stabilise the ground and protect the Network Rail tracks while we build the bridge over the River Pinn.

Our piling method
We will be installing sheet piles along the northern side of the Chiltern Line railway near the River Pinn.  Sheet piles are commonly used for retaining walls and underground structures to provide stability and support during excavation works.  These are sections of sheet metal with interlocking edges that are pushed into the ground along an area where future excavation work will take
place. When arranged side by side, the sheet piles form a wall to provide permanent or temporary earth support.

We are planning to use a pre-auger drill to loosen the ground and then push the piles into place using a vibration method. In the event that we find hard ground or obstacles, a vibro-hammer may be used for short periods of time to disturb the ground and drive the sheets through the hard areas.

Hours of work
Our working hours are Monday to Friday from 8am to 6pm and Saturday from 8am to 1pm.

Noise generating activities are scheduled after 8am and during standard construction hours. There will be a respite period of 45 minutes during the middle of the day when piling works will not take place.

What to expect
You may notice periods of increased construction noise, we would like to apologise in advance for any disruption or inconvenience this may cause Every effort is being taken to ensure that this work is carried out in the least impactful way, with various methods being utilised to ensure that disruption is kept to a minimum.

Noise and vibration monitoring will be in place throughout these works. We will also use water sprays to reduce the dust generated by these construction activities.

During the works, you may notice large construction equipment and machinery in our site including heavy goods vehicles, piling and excavating machinery, cranes, lighting towers and concreting equipment.
