The largest railway station to be built in the UK, Old Oak Common is also set to be the best connected with access to vast parts of the nation.
For this project, we provided over £1 million of piling services over the course of 12 months, including completing bearing piles to support cast in-situ retaining walls related to the lowering of Old Oak Common Lane, creating a new access into the new HS2 station and relocating an existing SSEN substation.
The piles were installed with a combination of rotary bored piling techniques using 900 and 600 mm diameter piles and segmental flight auger (SFA) techniques using 750 mm diameter augers. Piles ranged in depth from 12 to 35 m.

We carried out thermal integrity profile (TIP) testing and the installation of reinforcement cages with integral “L” bars for continuity into the pile cap. This required careful coordination between parties to ensure that working levels and fabrication details could achieve the required tolerances.
The area was also restricted, requiring us to work on an existing cut slope above an old gravity retaining wall. This meant surcharge loads needed to be kept as low as possible. We mobilised our Soilmec SR-75 piling rig to complete the rotary bored piling and utilised a Hutte 204 mini piling rig to construct the 750 mm diameter SFA piles.
