Description
Sellafield Ltd has a requirement to award a Contract for the manufacture and supply of Polyvinyl Chloride (PVC) Containment Items along with providing technical support for these items in support of Sellafield Ltd site Operations. This notice is to invite interested parties to submit a Tender for this scope of work, which includes information/interface checking, supply of materials, manufacture, assembly, inspection & testing at Contractor's works, packing, provision of documentation for PVC Containment items & Miscellaneous PVC items along with delivery.
PVC Containment items include PVC bags such as posting bags and blister bags. These bags are used on the handling of, and safe interim storage of, radioactive and toxic materials of a hazardous nature and must therefore be of suitable quality of mechanical strength, leak tightness, material reproducibility and general finish.
These items form the primary containment barrier layer between radioactive alpha material and the operator during glove box operations and maintenance. PVC items are used in production operations, retrievals and post operational clean-out plus long- and short-term storage of alpha bearing product and waste.
PVC tents are also required under this contract. These are temporary containment features erected around the work area to prevent contamination. Invasive maintenance and repair or decommissioning operations generally result in disturbing contamination as part of the process, but these activities cannot go ahead without this containment.
All PVC items produced must meet the relevant Sellafield Ltd Goods specification or be supported with the relevant concessions or manufacturing permits
The items will be ordered as required as call off orders and there is no guarantee of volumes. There is a requirement for inspection across the goods specifications
Full specifications and procurement documents for this tender are available to interested parties who register on Atamis project C10247, details on how to do this are contained within this notice.

Justification for not using lots
The competition will consist of one single Lot, and the goods and associated services will be awarded under one Contract to a single bidding entity.
Tendering and Lotting Options were assessed against the Critical Success Factors and the preferred option identified following this assessment was for the requirements of the scope to be supplied under one Lot by a single supplier. The reasons for not splitting this requirement into several smaller lots are;
• This option best enables the delivery of all CSF's.
• The environmental impact will be less through having a single supplier as opposed to a multi-supplier contract i.e., reduction in deliveries and CO2 emissions.
• Demand management will be better controlled through placing all orders through a single supplier, reducing the administration burden.
• Market Engagement activities have confirmed that a single Lot with a sole supplier is a more attractive package to the market than multiple lots, enabling greater competition
