## Summary

The procurement process pertains to the modification of Sidetipper Wagons by Network Rail Infrastructure Ltd, located in London, UK. This project falls under the services category, specifically focusing on repair and maintenance related to railways and associated equipment. The procurement was initiated as a tender, with the award confirmed on 9th September 2021, and has been classified as complete. The bidding process employed a selective procurement method, which involved prior call for competition. The initiative aims to implement a bespoke water-based dust suppression system to ensure health and safety compliance for workers involved in aggregate handling, alongside additional modifications to the existing wagons.

This tender presents significant opportunities for businesses specialising in railway services, engineering, or bespoke equipment modifications, particularly those with experience in health and safety provisions regarding hazardous materials. Suppliers that can provide innovative solutions for dust suppression and wagon modifications would be well-suited to compete in this arena. With an award value of over £2.2 million, successful participation in such contracts could contribute to substantial business growth within the rail industry.

## Notice

Design, manufacture, fitment, approval and testing of a bespoke water-based dust suppression system to 100 Network Rail Sidetipper Wagons to reduce exposure to Respirable Crystalline Silica faced by the Employer's employees, contractors and other personnel involved in aggregate handling activities. In conjunction with this, modification of the Sidetipper Wagons to protect against inadvertent toppling due to partial chute opening is required. Additionally, the installation of the 'Mark 2' Sidetipper Handbrake Interlock system to the 'Mark 1' fleet is required.

### Lot Information

Lot 1

The Technical Specification conveys the requirements for the design, manufacture, fitment, approval and testing of a bespoke water-based dust suppression system to 100 x Network Rail Sidetipper Wagons to reduce exposure to Respirable Crystalline Silica faced by the Employer's employees, contractors and other personnel involved in aggregate handling activities. In conjunction with this, modification of the Sidetipper Wagons to protect against inadvertent toppling due to partial chute opening is required. Additionally, the installation of 50 x 'Mark 2' Sidetipper Handbrake Interlock system to the 'Mark 1' fleet is required. Network Rail (the Employer) currently owns, operates and maintains a fleet of 100 x Sidetipper Wagons, consisting of 'Mark 1' and 'Mark 2' variants, that are permanently coupled together in sets of five (known as rakes) to deliver new aggregate (ballast) to rail worksites. Each rake has four identical wagons and a fifth that carries a diesel electrical generator, which in turn supplies hydraulic power packs on each wagon used to tip two independently controlled tipping boxes. Each generator can power up to a maximum of 10 wagons (2 rakes) in the event of generator failure. When offloading, particularly during dry ambient conditions, a significant plume of ballast dust, which contains Respirable Crystalline Silica (RCS) is observed. RCS is a known carcinogen, which after prolonged exposure can cause cancer of the lungs or other health conditions such as Silicosis. Therefore, it is the Employer's foremost obligation to protect the wellbeing of its employees, contractors and lineside neighbours. To deliver on this obligation, and to comply with the Control of Substances Hazardous to Health Regulations 2002 and the Health & Safety at Work etc Act 1974, the Employer requires an engineering control in the form of a water-based dust suppression system (the solution) to be retrofitted to the Sidetipper wagons to reduce RCS exposure. The existing Radio Controlled Handset system shall be modified to control the solution. In addition, to combine workstreams and limit Wagon outage, the Employer requires the completion of further wagon modifications: - Installation of 100 x Chute Proximity Switches. - 50 x 'Mark 1' Sidetipper Handbrake Interlocks upgraded to 'Mark 2'.
