Fire Pressure Regulated Valves Maintenance Eliz Line

Transport for London

Procurement identifier (OCID): ocds-h6vhtk-050d67

Description

Rail for London Infrastructure (RFLI), a TfL subsidiary, relies on Walter Frank, the OEM, for off-site servicing and calibration of life safety-critical PRVs used in the Elizabeth Line's fire hydrant system. Due to the specialist nature of the task and OEM-held intellectual property, RFLI cannot perform this work in-house. Serviced PRVs must be returned with a certificate of conformity and are warrantied until the next scheduled service.

RFLI manages 1,438 PRVs across the Elizabeth Line, requiring off-site servicing every 36 months to maintain fire safety performance. Walter Frank, the OEM, handles inspection, calibration, and certification. The scope excludes on-site work and routine visits, focusing solely on off-site servicing of 40 units weekly, with collection and return included.

RFLI is initiating a competitive procurement process for the off-site servicing and calibration of Pressure Regulating Valves (PRVs) across the Elizabeth Line. This contract will be awarded based on the Most Advantageous Tender (MAT), ensuring the selection of a provider that offers the best value in terms of quality, capability, and cost-efficiency. The process is designed to promote fair competition and remove any exclusivity, while maintaining compliance with OEM standards and safeguarding the operational integrity of the fire hydrant system.
