Fairlie Gabion Wall

The Project

The Fairlie site consists of a steep soil embankment on sidelong ground. Remote slope monitoring had been in place since 2012 which was showing progressive movement requiring remedial intervention. Further ground investigations confirmed poor quality of underlying ground makeup with rockhead at varying levels between 1.5m and 3.5m below ground level provided a challenge for installing a suitable foundation for the designed gabion basket remedial solution.

Scope of works

Working with our designer QTS were able to engineer
a mass concrete foundation solution down to rockhead for the gabion wall toe retention that allowed for all preparatory works to be carried out during disruptive possession. Maximising day-shift working to install 3m high gabion wall and bulk rockfill blanket (with trains running) contributed to minimising costs and reduced the safety risk to both our operatives and the operational railway.
