Framework
An agreement that sets terms for work the buyer may order later, often from several suppliers. The value shown usually covers the whole agreement, not one job.
Open for bids / closing date
You must submit by the closing date and time, normally through the buyer's own online portal. Late bids are normally refused.
Clarification questions
A deadline for asking the buyer questions about the tender. It is earlier than the closing date.
Conditions of participation
What the buyer asks suppliers to show before they can be considered, such as experience, insurance or accreditations.
Bids are scored on
How the buyer will compare bids, usually a split between price and quality. A 60/40 split in favour of quality means the cheapest bid will not necessarily win.
Lots
A tender can be split into parts. You can often bid for only the lots that suit you.
Area (ITL)
The buyer names an official statistical area for where the work is, not a street address. Check the tender documents for the actual sites.
UK4 and other notice codes
Official codes for the type of notice. A "tender notice" means bids are being invited.

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.
