## Summary

Liverpool City Region Combined Authority procured specialist engineering services to completely overhaul 14 industrial gearboxes supporting the Kingsway Tunnel ventilation system. The gearboxes have been in continuous service for approximately 50 years and require urgent replacement to reduce the risk of ventilation failure. The work concerns critical tunnel infrastructure and complex transmission equipment, rather than the supply of standard replacement units. Delivery is associated with the Kingsway Tunnel in Liverpool. The buyer is a sub-central public authority responsible for the Liverpool City Region. The requirement was classified as engineering services and covers the overhaul of the existing industrial gearboxes so that the tunnel’s ventilation infrastructure can continue to operate safely and efficiently.

The procurement is complete and the contract was awarded by direct award to Radicon Transmission UK Ltd. The award value is £384,332.60 excluding tax, or £461,199.12 including tax. The contract period runs from 10 August 2026 to 9 November 2026. The direct award was justified by the specialist nature of overhauling 14 gearboxes, their critical role in tunnel ventilation, the need to minimise downtime, and the safety risks associated with failure. The authority identified Radicon as a recognised specialist with expertise in designing, manufacturing, servicing and overhauling industrial gearboxes. The procurement used one lot and was treated as above the relevant threshold for the award.

This requirement demonstrates demand for specialist industrial gearbox refurbishment in critical public infrastructure, where reliability, safety and limited operational downtime are central to supplier selection. A credible competitor for similar work would need proven expertise in the overhaul of complex transmission equipment, including ageing gearboxes that have operated continuously for many years. Relevant capability would include inspection, diagnosis, refurbishment and replacement of components, with the engineering capacity to manage multiple units as a coordinated programme. Experience of working on ventilation or other safety-critical infrastructure would strengthen a supplier’s position, as would a clear ability to control operational risk and minimise disruption. The buyer’s direct-award rationale also shows the importance of recognised specialist status and demonstrable technical expertise.

## Notice

The gearboxes are integral to the efficient operation of the tunnel's ventilation infrastructure. The original gearboxes have been in place for 50 years and require urgent replacement to avoid failure of the ventilation system. This procurement seeks to engage the services of a specialist supplier to carry out complete overhauls of the gearboxes.

### Procurement Information

4.4 A direct award is considered the most appropriate procurement route as the estimated contract value of PS384,332.60 is well below the applicable works threshold and the requirement relates to the specialist overhaul of 14 industrial gearboxes that have been in continuous service for approximately 50 years as critical components of the Kingsway Tunnel ventilation system. Radicon Transmission UK Ltd is a recognised specialist in the design, manufacture, servicing and overhaul of industrial gearboxes with extensive expertise in the refurbishment of complex transmission equipment. Given the criticality of the ventilation system to the safe operation of the tunnel the significant operational and public safety risks associated with gearbox failure and the need to minimise downtime a direct award represents a proportionate, value-for-money and risk-based procurement approach.
