Organization: NR
Publication Date: 6 June 2020
Status: inactive
Page Count: 20
scope:

This work instruction outlines the procedures for reporting geotechnical incidents.

Reportable incidents include the following earthwork failure types:

 a) Slope failures;

 b) Failures of nailed or reinforced soil structures;

 c) Failures of rock slope support systems;

 d) Mining related failures.

Further details of earthworks failure types can be found in Appendix A.

Procedures for reporting M6 earthwork failures are documented separately under NR/L3/CIV/185/01.

Purpose

This work instruction manages, 'the receipt of ad-hoc reports from train operating companies, freight operating companies, Network Rail staff and earthworks reporting procedures', to mitigate the risks of:

 a) loss of track support and/or track geometry;

 b) slope failure leading to loss of kinematic envelope and/or track geometry.

intended Use:

NR/L3/CIV/185 ISSUE 2 and  NR/L3/CIV/185/01 ISSUE 1 were withdrawn prior to publication, in April 2020.
