Contractors

Every firm named on a section: what it built, where, and how that work ran against its contracts.

Only construction counts toward these figures. A design contract is listed on the firm's page and never folded in, because a construction overrun belongs to whoever built the thing.

Work done in a joint venture is credited to each member firm, so a venture has no page of its own and never appears beside its members: that would count one section twice.

Name variants are not merged

71 of 91 firms here match no entry in the contractor registry, so two spellings of one company rank as two firms. That is a gap in data/contractors.json, and every one of them is already a data validation warning.

Delivery record

Firms credited with at least 2 sections, worst median slip first. Measured exactly as on the performance page.
