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.

Details of Stair E — Lower Stories

Sheet W225

Extraction: Reviewed · extraction partial. Text-first review followed by one complete upright source and sequential crops from the same photograph. Reviewed title block, intermediate-landing plan, Sections A-A/B-B/C-C, gate detail, railing detail and major finish/component callouts. A later sequential Section A-A crop verified the depicted two-flight basement-to-first topology, three-flight first-to-second topology, associated landing counts, handrail-at-beam brace, flush wood block, terrazzo-floor/marble-base interface and unplastered basement joint. Duplicate/companion photographs IMG_1115 and IMG_1116 were identified but not opened. Partial timed visual review: Text-first OCR/queue/prior-package audit only; existing verified properties reused without duplication. Orientation not rechecked where null. Partial timed visual review: Section A-A basement-to-first independent tread recount. Two crops; upper dashed/hidden portion remains a candidate. Partial timed visual review: Bounded endpoint/profile regions only; no complete-sheet extraction or physical geometry approval. Partial timed visual review: Selected fine closure only; not exhaustive source extraction. Partial timed visual review: undefined Partial timed visual review: Text reuse only; no fresh pixel evidence or exhaustive-review claim.

Highlighted reading: SEE ALSO DRAWING NO. 228. One complete source and sequential crops from the same photograph were inspected. Pixel distances were not used as architectural dimensions.
