This page is the method, published in full: how a public document becomes a record, how a record is verified, how the count for an area is computed, and the lawful use rule every source is held to. A subscriber never has to take the feed's word for any of it.
For the reader companion to this page, see Resources: plain language explainers on how to read a bid record, what bidding stage means, and how a count is verified.
Every record travels the same three steps, and each step leaves its evidence on the record.
A permit is issued, a solicitation is published, a procurement posting goes up. Public records, created by the project itself. Nothing enters the feed from anywhere else.
The same project arriving from three sources becomes one record, with its stage history kept intact and its source named on it, so you can check it yourself.
The record is scored against your trade or your category and lands on your list while the bid window is open, with the deadline attached, and every later change lands as a dated event.
One count per metro, counted the same way every period, and the method is published with it.
Verification is a read, not a label. A record earns its place in the feed by being checked against the document it came from.
The feed is built only on data it may lawfully use, and the rule is stated here so it can be held to.
