How to win: Tunnel Segment Production Monitoring System

About this contract

This project involves the manufacturing, transportation and installation of approximately 39000 precast concrete tunnel segments. The segments will be produced at Avonmouth tunnel precast factory, transported through a multi-modal logistics network (truck and train interfaces), stored across 4 facilities (TPF, Railhead, ACA and TLC), ultimately installed within three TBMs serving two intake tunnels and one outfall tunnel configuration. This operation requires complete end-to-end visibility from the moment a segment is cast until it is installed within the tunnel structure. Currently, critical gaps exist in reporting, quality traceability, inventory discrepancies, and segment tracking across the supply chain. A comprehensive traceability system is essential to manage the entire lifecycle, prevent installation errors, ensure quality compliance, eliminate segment duplication, and maintain supply chain transparency across all stakeholders.
