Management of Reports of Safety Related Geotechnical Incidents
|Publication Date:||6 June 2020|
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.
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.
NR/L3/CIV/185 ISSUE 2 and NR/L3/CIV/185/01 ISSUE 1 were withdrawn prior to publication, in April 2020.
