## Description
Yorkshire Water is conducting a Tender Notice to inform the development of a procurement strategy for specialist ozone maintenance and minor capital works across its ozone process-plant estate.
The proposed framework will support end-to-end planned and reactive maintenance, technical support, emergency response and minor capital works associated with ozone-generation systems and related assets. This will include asset inspections, condition and performance assessments, fault diagnosis, breakdown repair, critical-spares management, obsolescence management, equipment replacement, refurbishment, upgrades and remediation. The scope may also include mechanical, electrical, instrumentation, control and automation works, testing, commissioning, performance validation, warranty support and the provision of maintenance documentation, asset data and operating guidance.
Major design-and-build capital schemes are excluded from the framework and will be delivered through Yorkshire Water's Tier 1 suppliers.
Suppliers with relevant experience and capability are invited to express interest and participate in the CoP.
