Lots and requirements (4)Procurement structure

4 lots · all with a published value

Every one of these 4 lots carries the same published figure, £7,916,667: it is the framework's maximum for the whole notice, not each lot's own budget, and no share per lot is published. The cards below say ceiling above rather than repeat it.

Lot #1Design and Build FrameworkAwarded 1 yrceiling above

This Procurement Project is to create a Framework for the delivery of future projects relating to the Fusion Futures programme. This Framework is designed for the Fusion Futures Industry Capability programme but not limited to it.
