What is being bought

Published requirement description

A single operational facility will be stood up to facilitate high priority test activities. This facility is likely to be an existing commercial lease unit. Enabling initial operations to occur, with a later migration to bespoke buildings in 2-4 years’ time, these will be located on or close to the West Burton Power plant site – a repurposed Coal Fired Power station site, that will accommodate the novel Prototype Fusion Power Plant being delivered by STEP.

The tests that will be accommodated in this facility will involve many FOAK physical test rigs comprising of; Scaled Superconducting Magnets Testing, High Power Microwave Testing, Novel Cooling Cycle testing through high temperature turbo machinery, Control Room simulator and other smaller activities. Each will have its own complexities and operational risks/hazards that must be managed appropriately (including but not limited to: Hazardous Voltages, Pressurised Systems, Flammable substances, Cryogenics, High Magnetic fields/ Radiofrequency energy, (note that no radioactive testing is planned in this facility at this initial site). Co-ordinating of these activities is crucial for programme success, using digital tools / BIMS for space allocation etc. Please find more information within the attachment.

Question for the bid
This buyerUK Fusion Energy Ltd · division 71
What to do with it
How often do SMEs win?
i

How often small and medium firms win.

Share of awards where the winner’s size is known.

The counts under this question show how many awards have a known supplier size.

Last 36 months.

Buyer: 6 of 17 known-size awards · market: CPV 7131 · UK-wide, n=1,199
35%56%

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
i

How often local firms win similar work.

Winners with a registered address in the delivery region, out of awards with a known address.

Local means the winner is registered in the region where that award was delivered.

3 of 351%

Most of this buyer’s recorded winners were registered in the region where that award was delivered.

How long to a decision?
i

How long buyers here take to decide after bids close.

Middle value in days from the bid deadline to the award date, on competitions that published both.

Only decided tenders count, so slow ones still waiting are not in.

Last 36 months.

Buyer: 11 decided notices · market: CPV 7131 · UK-wide, n=226
25 days48 days

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
