The project is to procure a specialist post-incident cleaning service for Northern Trains Limited, providing both reactive and planned cleaning support across the rail network. The service is required to ensure rolling stock, depots and operational facilities can be safely and efficiently returned to service following contamination incidents, vandalism or other specialist cleaning events. The scope of works includes the provision of trauma and biohazard cleaning services following incidents involving blood, bodily fluids, fatalities, serious injuries, infectious contamination and other hazardous materials. The supplier will be responsible for the safe cleaning, decontamination and disposal of waste in accordance with relevant legislation and industry standards. The appointed supplier will also undertake specialist cleaning activities arising from animal strikes, toilet and sewage contamination, and vandalism incidents, including graffiti removal from rolling stock and associated assets. Services may include deep cleaning, sanitisation, odour removal, decontamination and restoration of affected areas to an operational standard. In addition to reactive incident response, the contract will cover planned specialist cleaning requirements as instructed by Northern Trains Limited. The supplier will be required to provide a fully managed service, including suitably trained personnel, specialist equipment, materials, waste management and reporting, together with a 24-hour response capability to support operational requirements across the Northern network.
