Ground Investigation – LUL Snaresbrook to Leytonstone

12.01.16

REC Ltd was commissioned by Clancy Docwra (Rail Division) on behalf of Pell Frischmann Ltd to conduct ground investigation works on a railway cutting between Snaresbrook and Leytonstone stations.

The GI works were undertaken to assess the extent of Made Ground across the surface of the cutting and obtain further information on ground conditions existing within the cutting to enable assessment and design to facilitate stabilisation works to be undertaken.

REC conducted a ground investigation during traffic hours. The ground investigation comprised 2 window sample holes drilled to a nominal depth. 5 hand excavated trial pits to a nominal depth and 3 in-situ soil density tests by sand replacement method. Additionally, all intrusive locations were surveyed in and with of section lines referenced to LU Grid Co-ordinates being produced. REC were able to provide its own LUCAS certified engineers to supervise site works on LU operated ground.

Both Geotechnical and geoenvironmental samples were submitted to UKAS accredited laboratories for client specified analytical suites and a factual geotechnical report was provided to the client.

REC were able to provide its own LUCAS certified engineers to supervise site works on LU operated ground. Facilitated easy access to the embankment slope and delivered significant cost savings over a modular cable percussion rig, the use of which would have required the use of a crane for mobilisation onto site.
