In June 2020, an extreme flash flooding event severely damaged several sections of embankment and an adjacent property in the Lochailort area of the Fort William to Mallaig railway line, Scotland.

Following emergency repairs by QTS and Story, along with a further extreme rainfall event in August 2020, Network Rail commissioned QTS through their Renewals and Enhancement (R&E) Framework Contract to design and implement a long-term permanent solution to reduce the likelihood of infrastructure damage from future extreme weather events.
Fairhurst were engaged as design consultant partners and carried out a comprehensive catchment area analysis based on visual inspections along with multiple phases of intrusive investigation and topographic survey data undertaken by QTS in-house resources. Early consultation with key stakeholders including SEPA, local estate/landowners and the road authority (due to A380 trunk road downstream from the site) ensured that our proposed solution considered mitigated flood risks for all parties involved.
