No conditions of participation were published on the notice; check the tender documents.
- Price carries 60 of 100 points — a 10% discount moves about 6 points. This one is won on the number — sharpen the price before polishing the prose.
- Turnover usually expected at this size: about £300,000 (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.
Competition analysis · published record, not a forecast of who will bid
How Dartford Borough Council buys Construction work for pipelines, communication and power lines, for highways, roads, airfields and railways; flatwork (CPV 4523) — and who usually turns up
Dartford Borough Council’s own published record, next to the published market for the same work. Frameworks and DPS are kept out: they attract a different number of bids.

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 South East England.
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered in South East England.
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 108 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.
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.

Coverage and what to read with care
- Each figure explains itself. The on a figure says what it is, how it is counted and which scope this notice’s own record came from (class, division, all categories, or the authority’s 24-month row). The two sides are never blended. A lot’s own market is read at its delivery region where the lot names one; where it names several, or none that can be resolved, the chart falls back to the UK-wide record for the same category and says so under the bar. An empty cell means the source published nothing usable. Long form: Methodology.
- When we call out a difference. A buyer figure is only flagged against the market when the sample is large enough that the gap is unlikely to be chance; at most two callouts appear, always phrased as a comparison with both numbers and the sample size.
- Coverage (re-measured 5 Oct on the live record, 94,497 awarded procedures of the last three years). 51 % publish a bid count and 72 % a delivery region, so the market column reads the authority’s registered region when the notice names none, labelled. Of the 17,687 award-vs-estimate pairs, 34 % sit exactly on the estimate — the buyer published the award at the figure it advertised. n is on every figure; a thin sample is muted, never hidden, and a distribution is not drawn as percentages below ten observations.
- “Match”, text similarity, the expected-bid figure and the distribution drawn beneath it are model outputs, not published facts or win probabilities. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
