DLSITT1097 - Main Septum Magnets for Diamond-II
Authority: DIAMOND LIGHT SOURCE LIMITED (Central government)
What is being bought
Published requirement descriptionLocated on the Harwell Science & Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. DLS allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level. To continue delivering the world-changing science that Diamond enables, the facility is being upgraded to Diamond-II, a co-ordinated programme of development that combines a major machine upgrade with new instruments and complementary improvements to optics, detectors, sample environment and delivery capabilities, and computing, as well as integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences.
The scope of this contract is to carry out the detailed design, manufacture, quality control, testing and delivery of two out-of-vacuum main DC/PM septum magnets, with integrated vacuum vessels, on support stands, as well as some spares.
The two septum magnets are physically identical but will be installed with input and output ends inverted for booster extraction bend to the left, and storage ring injection bend to the right. This means that the magnet fields are also inverted, and also that the support frame should be rotationally symmetric so that the services connections are on the outside (bending channel side of the support frame) in each case.
See specification for further details.

- Price
No conditions of participation were published on the notice; check the tender documents.
- Price carries 45 of 100 points: a 10% discount moves about 4.5 points. Quality carries 55 of 100: the paper moves it further than the discount.
- Turnover usually expected at this size: about £570,359 (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. The market figure counts awards delivered in South East England.
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 25 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), 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.
