Controlling the Risk of Earthwork Instability During Mp&I Civils Excavation Works

inactive, Most Current
Organization: NR
Publication Date: 19 February 2007
Status: inactive
Page Count: 19
scope:

This procedure applies to all MP&I Civils works involving excavations that have the potential to destabilise railway embankments and cuttings, and includes, but is not limited to:

• Planned and Unplanned Works

• Earthwork Repairs and Renewals

• Minor Works

• Drainage works.

This procedure may however be adopted by other functions if the excavations they are responsible for have the potential to destabilise railway embankments and cuttings.

Purpose

The purpose of this procedure is to standardise measures to control the risk of earthwork instability during MP&I Civils excavation works. A standard approach is defined for determining when a Temporary Works Design is required on projects involving excavations within or adjacent to embankments or cuttings. It also identifies a requirement to use the Work Package Planning Process, as defined in Network Rail Company Standard NR/PRC/MPI/CP0044, to enable the clear communication of Temporary Works Design assumptions and requirements to the construction workers.
