Halcrow is currently monitoring a 3km section of the Folkestone Warren chalk escarpment for its current owner, Network Rail.
Part of the main Folkestone to Dover railway line is built on an active landslide and, as part of a five-year framework, Halcrow is capturing and analysing data on the unstable escarpment. This provides the client with a comprehensive view of the entire Warren, enabling Network Rail to keep track of potential movements.
As well as traditional monitoring techniques, Halcrow is using terrestrial laser scanning to provide information on the inaccessible – and previously unsurveyed –high cliffs. The resulting data and analysis gives the client an improved understanding of the entire area, along with an early warning of any imminent changes
