    Brief

    This project requires a comprehensive monitoring and traceability solution for the production, transportation, storage, and installation of approximately 39,000 precast concrete tunnel segments. Segments are manufactured at the Avonmouth tunnel precast factory and distributed through a multi-modal logistics network involving truck and train transport, with storage across four facilities (TPF, Railhead, ACA, and TLC) before final installation in three tunnel boring machines (TBMs) serving two intake tunnels and one outfall tunnel. The system must provide complete end-to-end visibility and tracking from casting through installation to address critical gaps in reporting, quality assurance, inventory management, and supply chain transparency. Key requirements include real-time segment tracking to prevent installation errors, maintain quality compliance, eliminate duplication, ensure accurate inventory across all storage locations, and enable seamless coordination among all stakeholders throughout the supply chain lifecycle.
