The lotProcurement structure

HIAL seeks to procure a suitably qualified supplier to provide a replacement Primary Surveillance Radar system for Sumburgh Airport. The scope of the contract includes the detailed design, manufacture, supply, installation, commissioning and acceptance of the radar system, together with all associated documentation, testing and regulatory support required to achieve operational readiness. The precise scope of any future procurement remains under development and forms part of the purpose of this market engagement exercise.
The procurement forms a key element of a wider Sumburgh PSR Replacement Project. Associated activities including land acquisition, provision of electrical power and communications points of presentation, certain property matters and ongoing maintenance arrangements fall outside the proposed contract scope. The supplier will be expected to provide and deliver the infrastructure, radar compound, civil engineering and associated works required to deliver an operational capability from the defined points of presentation. The final allocation of responsibilities between HIAL and the appointed supplier will be confirmed as part of any future procurement process. Additional information: HIAL invites interested suppliers to complete the accompanying Request for Information (RFI) relating to the potential Primary Surveillance Radar replacement at Sumburgh Airport. The information received will be used to assess market capability, indicative costs, delivery timescales, risks and support the development of the procurement strategy.

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 outside 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 36 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.

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.
