Detailed design and build of a scaled down Fast Acting Low Conductance (FALCON)
Authority: United Kingdom Fusion Energy Ltd (Public body)
The scope of this work is to provide the detailed design and manufacture of a scaled down Fast Acting Low Conductance valve (FALCON) prototype which will be used to safeguard the proposed exhaust vacuum pumping technology against Disruption mitigation or sudden massive air ingress events for the STEP Prototype Powerplant (SPP). The scope of work includes the detail design and build of a scaled down prototype, which includes everything within the Vacuum Gate/Isolation valve casing (including the casing itself), mainly the actuation mechanism and the seals required to maintain both the operation of the isolation valve and the vacuum integrity of the process gas line.

Published requirement descriptionThe scope of this work is to provide the detailed design and manufacture of a scaled down Fast Acting Low Conductance valve (FALCON) prototype which will be used to safeguard the proposed exhaust vacuum pumping technology against Disruption mitigation or sudden massive air ingress events for the STEP Prototype Powerplant (SPP).
The scope of work includes the detail design and build of a scaled down prototype, which includes everything within the Vacuum Gate/Isolation valve casing (including the casing itself), mainly the actuation mechanism and the seals required to maintain both the operation of the isolation valve and the vacuum integrity of the process gas line. The fast-acting nature of the valve requires it to reach its defined ‘close’ position within 37.5 ms.

No conditions of participation were published on the notice; check the tender documents.
- Price carries 30 of 100 points: a 10% discount moves about 3 points. The method statement decides this lot, not the discount.
- Turnover usually expected at this size: about £397,820 (twice the annual value).
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula. Turnover is an indicative market norm (≈2× annual value), not a published condition.

How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
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.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
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.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners were registered in the region where that award was delivered.
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.
Half of these awards have an award date within 26 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
Both shares are minimums: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.
Each colour is a bid-count range. Only competed lots with a published count are included.
Past bids do not predict this tender.

How did awards compare with estimates?

Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
Past prices are a guide, not a bid price.

About this data
- Source. Official UK public procurement notices (Find a Tender and Contracts Finder), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly. Contracts Finder appears in live search, the Retender Radar, contract pages, organisation counts and the buyer's decision figure; the other analytical figures are built from Find a Tender notices.
- 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.
