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.

Madison Street elevation

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial: façade opening identities/counts and selected printed datums. Drawing number, registration and opening dimensions still unresolved. Partial timed visual review: Text-only prior evidence inventory; catalogue labels are discovery-only and prior verified identity retained. Partial timed visual review: Source-local architectural evidence only; no physical registration, installed quantity or accepted geometry. Existing verified measurements omitted; conflicting locator readings preserved. Partial timed visual review: Text-only reuse disposition; no new image-view attempt and no new visual evidence.

Unresolved extraction work

Physical plan registration: No readable horizontal station chain or overall width occurs in the three assigned full elevation photographs. All station_ft, width_ft, height_ft, sill/head values remain null. Register traces to separately extracted foundation/floor-plan controls before 3D physical placement.
Main full-elevation count: Assigned IMG_1241 is a lower corner crop. Inspect candidate full Main source separately; archive index titles may be wrong.
Sheet numbers: Title blocks omitted or cropped in assigned views. Sheet numbers cannot be responsibly invented from image sequence.
Upper level variation: Left-edge F7 chain is 171.75; Madison upper-opening reference is 173.75. Preserve both; do not impose a single universal F7 floor slab. Ambiguous secondary annotation on IMG_1233 not used as separate numeric measurement.
Main second-floor label conflict: IMG_1241 prints 125.75 at both second and third floors. Its 21′0″ and 11′6″ chain and IMG_1233's explicit second114.25 contradict the second-floor label.
Opening dimension schedules: OCR identifies IMG1250–1252 as upper-story Broadway details, IMG1253–1254 as heavy-type casement windows including basement/penthouse sash. These have not been visually measured in this bounded pass. No exact opening width/height can be inferred from elevation scale alone.
Lower envelope and attachment profiles: OCR/index companions identify lower elevations/grilles, balustrades, steps, Broadway/Madison entries. Numeric profile projections remain null pending these details.
Rooftop and small ancillary openings: Main-volume counts exclude rooftop stair/penthouse openings, vents, grille subpanels, door leaves, and facade lighting. Separate records required for an exhaustive whole-building object inventory.
Sill/head datums: The drawn opening rectangles support approximate image bboxes only. Floor datums are not opening sills or heads. Do not replace missing sill/head values with floor lines.
Unreadable minor marks: Some parapet/grade spot levels, window schedule circles, and faint marginal annotations remain unreadable within the four-full-image/eight-crop visual budget. This dataset is a bounded extraction, not a claim that every number in the archive has been transcribed.
Finished/rough/structural boundary classes and physical source-to-plan registration remain unaccepted.
Remaining fine dimensions, all material/finish schedules, notes and historical revisions need regional and companion review.
No installed quantity, geometry, as-built state or architectural release is accepted.
Separate regional F7 scope, roof notes and upper opening details
Widths, classified witness edges and all fine window/type marks
Grade endpoints and boiler-floor historical conflict reconciliation
Original sheet identity, code and revision authority
Exact dimensions and witness endpoints not fully extracted
Companion-detail, revision and floor/room registration unresolved
All-region review and modeling acceptance incomplete
No pending printed/observed source readings in selected queue snapshot; explicit remaining window keys, fine widths/profile endpoints and roof notes still require independently targeted evidence.
Classified finished/rough/masonry/frame witness endpoints and installation registration remain unresolved.
Companion drawings, original/revision authority and as-built applicability remain unresolved.
Complete remaining notes, courses, profiles, opening construction and whole-source/model acceptance remain outstanding.

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.
