Tender Notice
Summary of the contracting process

The public procurement process initiated by Sizewell C Limited focuses on a project titled "Tunnel Segment Production Monitoring System." The procurement falls under the industry category of Tunnelling Works, with a primary location in regions including London, the South West, and South East of the United Kingdom. As part of the tender stage, this project requires complete lifecycle management of approximately 39,000 precast concrete tunnel segments. The tender was published on 6th August 2026, with submissions due by 14th August 2026. The planned contract period spans from 3rd March 2027 to 3rd December 2034. This procurement is significant, with a total value of £500,000, highlighting its scale and importance to the infrastructure developments in the regions mentioned.

This tender offers substantial opportunities for businesses involved in manufacturing, logistics, and installation services related to tunnelling applications. Companies with expertise in creating comprehensive traceability systems are well-suited to address the project's current gaps in reporting, quality traceability, and inventory management. Firms with a robust logistical network capable of multi-modal transport and high standards of quality compliance would find this project especially appealing. While the tender is not explicitly targeting SMEs or VCSEs, larger organisations with significant resources in tunnelling and supply chain transparency can certainly leverage this opportunity for business growth.

Notice Information

Notice Title

Tunnel Segment Production Monitoring System

Notice Description

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.
