For reporters, researchers, and civic technologists

Use Chicago's demolition pulse as a source.

Current figures, reproducible downloads, direct municipal provenance, and a clear line between public permit facts and Salvage Signal's ranking heuristic.

Current story angles

Three facts worth a closer look.

Material clue

11 current records name masonry or brick.

That supports further reporting about recovery timing, but not a claim that reusable brick is available.

Timing clue

1 records currently rank time-sensitive.

Urgency is a text-and-recency heuristic. Confirm the actual demolition schedule with an authorized project party.

Public window

17 demolition-related records clear the current screen.

The ranked window changes as the City feed changes; dated Wire editions preserve citable snapshots.

Method and limitations

Salvage Signal filters demolition-related records from the official City dataset and scores public language associated with structure, material, scale, and timing. The score is not an engineering assessment, environmental review, appraisal, inventory confirmation, access grant, or statement that salvage is feasible.
