TNCEA - Unexploded Ordnance Detailed Desk Studies for England Ecosystem Survey
Authority: NATURAL ENGLAND (Defra Network eTendering Portal)
What is being bought
Published requirement descriptionNCEA is a transformative programme to understand the extent, condition and change over time of environmental assets across England's land and water environments, supporting the government’s ambition to improve the environment within a generation. A key element of the NCEA is the England Ecosystem Survey (EES) which aims to assess the current state of vegetation, habitats, landscapes and soils in England and to monitor long-term changes. Unexploded ordnance (UXO) risk assessment studies will be used to ensure the safety of all surveyors on each EES monad when carrying out soil surveys. The requirement is to deliver up to 272 detailed desk studies and risk assessments on selected sites. Sites are within 1 km x 1 km squares, called monads, boundaries of which are provided by Natural England. Pre-desk studies identifying the need for a detailed desk study for these sites have already been delivered as part of a previous contract.

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.
Here, local means registered in Greater London (authority’s region).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside Greater London.
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced within 3 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.
The market share is a minimum: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Awards are recorded, but published direct routes and bid counts do not establish this buyer’s share.
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.

How did awards compare with estimates?

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.
