What is being bought

Published requirement description

Located 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 K04 beamline will be an ultra-high throughput Macromolecular Crystallography beamline optimised for the study of biological samples (fragment screening) to support the XChem facility in early-stage lead drug discovery. K04 will greatly increase DLS's capacity to carry out XChem experiments by up to 20x, accelerating drug discovery timelines and related research for both the academic community and industrial customers.

The monochromator system shall include the VACCS cooling system (Vacuum Aspirated Cryo Cooling System) and three crystal sets. This full system will be developed in collaboration with engineers at DLS.

The minimum scope of the contract is the design, manufacture, test, delivery, installation and commissioning of:

  • A horizontally deflecting, asymmetric cut, double crystal monochromator (DCM)
  • The crystal sets and interfaces with DLS-designed cooling system(s)
  • Vacuum system in line with DLS Vacuum requirements
  • Crystal support and manipulation system
  • Interfacing with beamline services.

See specification for further details.

What this means for your bid
  • 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 £427,642 (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.

Question for the bid
This buyerDIAMOND LIGHT SOURCE LIMITED · all categories
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: 36 of 40 known-size awards · market: CPV 3311 · South East England, n=10
90%60%

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. The market figure counts awards delivered in South East England.

A local branch does not count if the registered address is elsewhere.

Last 36 months.

Buyer: 14 of 29 known-location awards · market: CPV 3311 · South East England, n=13
48%46%

Most of this buyer’s recorded winners were registered outside 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: 33 decided notices · market: CPV 3311 · UK-wide, n=9
30 days40 days

Half of these awards have an award date within 30 days of the bid deadline.

How often single-bid or direct?
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.

Last 36 months.

Buyer: at least 15 of 72 procurements with awards had no recorded rival · market: CPV 3311 · South East England, n=22
21%73%

Missing bid counts may hide more single-bid awards. This share is a minimum.

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.

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.
