183592 CP7 Earthworks Asset Monitoring Capital Delivery Western Framework

The project scope is for surveys and monitoring in the Western route for Geotech. This will roughly consist of four key workstreams. The first work stream is the installation of Earthwork Failure detection systems, these are utilised to detect failures and inform Route Control of earthwork movement. The second is Cant and Twist Sensors, these are track sensors installed at rail level to detect movement in embankments. The third is survey works called Ground Investigation Assessments (GIA), this is pre renewals works to install monitoring such as Piezometers/inclinometer to detect movement or changes in earthworks, technical reports and further recommendations may be requested as part of this workstream. The final is the ongoing maintenance of existing assets, ensuring they are kept live, functional and the systems communicate with route control. For EFD sites this might mean vegetation clearance around cameras, replacement when they are damaged and similar with the Cant and Twist schemes.
