Details

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.

Documents

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this construction & infrastructure opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
