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.

Main Street elevation—cornerstone and grade detail

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: Source-local photographed design detail; no installed quantity, accepted geometry or world placement authorized. Partial timed visual review: Source-local photographed drawing evidence only; stacked marks are interpreted as drawing references, not historical entrance identifiers. No installed quantities or accepted geometry. Partial timed visual review: Three sequential views: sips locator displayed sideways because of EXIF handling, then correct raw raster rotation90 clockwise lower region and targeted handwritten grade glyph. New regions refer to correct 3024×4032 upright raster; no historic grade digit guessed. Partial timed visual review: One sideways master locator only; lettering requires 90 degrees clockwise. Intended grade/parapet region not reached within ten-call budget. Existing envelope text reused; no new numeric receipt. Partial timed visual review: Source-local derivative corroboration only.

Highlighted reading: 13′-0″. Upper is first-floor datum; lower chain endpoint corresponds basement datum, not a universal sidewalk height.

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.
Remaining fine dimension chains, fractions, material schedules and revision annotations need targeted review
Floor/room and installed-instance registration, quantities, finishes and companion callout reconciliation unresolved
Full-region extraction and architectural acceptance remain incomplete
Remaining dimensions, fractions, all notes, revisions and material hatch application need region-by-region review
Reference sheet correspondence, historical instance/floor/room registration and independent checks unresolved
Extraction partial; modeling/checking not accepted
Remaining fine dimensions, notes, callouts, revisions and physical instance registration; no completeness or acceptance claim.
