Surepath Consulting recently completed a commission in Colsterworth, Lincolnshire, where a planned highway improvement had identified the need to appraise the stability of an existing road embankment over a culvert. Geo Matters Limited  were retained by their client to undertake the ground investigation and the stability appraisal, but due to the specialist nature of the latter (including  traffic impact loads and vegetation effects). Surepath were retained to support Geo Matters to undertake the stability analyses and prepare a Geotechnical Design Report in accordance with EC7. The aim of the work is ultimately to secure adoption of the highway.
