The measured building.

Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.

Source photographs: 464
Identified objects: 4872
Verified printed values: 12046
Disputed values: 20

464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.

Extraction: Reviewed · extraction partial. Partial timed visual review: undefined Partial timed visual review: Partial text-first sequential locator review using <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1179.webp. Lettering upright; access-image normalized regions. No full region review or model geometry claim. Partial timed visual review: Prior evidence reused; no new image inspection. Partial timed visual review: undefined Partial timed visual review: Additive selected region follow-up; previously verified findings omitted. Dimension witnesses apply only to depicted source-local spans. Extraction partial; modeling not started. Partial timed visual review: undefined Partial timed visual review: Partial regional review; prior closed properties reused. Each new numeric value is source-local only; no building coordinate, installed total or geometry approval follows.
