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: Partial text-first then sequential <=1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1252.webp. Selected legible source regions only, not full measured extraction. Coordinates normalized in unrotated access image; principal lettering upright. No model geometry authorized. Partial timed visual review: Printed specification or source-local detail only; no installed quantity, accepted room geometry, host placement or building transform established. Partial timed visual review: undefined Partial timed visual review: Library-head section is local evidence only; floor and room placement remain unaccepted.

Highlighted reading: 12" C. Section designation only; exact channel series, weight and profile not established.

Unresolved extraction work

locator review only; full region coverage, remaining dimension chains, fine fractions and dense notes outstanding
material-code schedules, revisions, annotations and companion detail reconciliation
historical building instance/room registration, quantities and missing finishes
Remaining small dimension fractions, profile boundaries, fasteners and dense notes require targeted master/clearer companion review
Installed instances, quantities, room registration and revisions remain unresolved
All-region measured extraction and architectural acceptance remain incomplete
Remaining fine offsets, reinforcing, closed profile and W413 companion applicability remain open.
Full prior profile_dimensions questions remain open; one vertical witness cannot close them.
Remaining regional dimensions, notes, schedules, fasteners and companion details are not fully extracted.
Original/revision authority, installed instances, quantities and room/floor registration remain unresolved.
Source-local evidence is excluded from model authoring and architectural release.
Complete profile and fine fractions
W413 companion review, historical installed correspondence and independent checks

Printed values, calculations, image traces and observed counts are different kinds of evidence. “Verified” applies to the specific reading—not to the whole room or model.
