## Summary

Network Rail Infrastructure Limited is planning a procurement process for the "183592 CP7 Earthworks Asset Monitoring Capital Delivery Western Framework". This initiative focuses on geotechnical engineering services in the Western route and is part of the works procurement category under the utilities special regime. The engagement phase invites suppliers to participate in a market engagement questionnaire by 1 April 2026, aiming to gather insights into supplier capabilities and interest levels to shape the procurement strategy. The tender process is scheduled to begin with document submissions by 10 April 2026, with the award expected by 8 June 2026. The procurement method employed is the open procedure, promising transparency and access to various potential participants including SMEs and VCS organisations.

This tender presents substantial growth opportunities for businesses within the geotechnical engineering sector, particularly those involved in test drilling, boring work, and ground investigation services. As Network Rail seeks to install and maintain Earthwork Failure detection systems and survey technologies, firms with expertise in sensor installation, system maintenance, and vegetation management will find this framework beneficial. Suitable businesses would be those able to demonstrate technical and economic competence, aligning with the Construction (Design and Management) Regulations 2015. Moreover, the contract allows for a maximum extension of three additional years contingent on performance, offering further long-term prospects for capable suppliers.

## Notice

The project scope is for surveys and monitoring in the W&W 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.
