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 exterior center framed-entrance physical gate; no finite frame or host-wall cut authorized. Main exterior center framed-entrance physical gate; no finite frame or host-wall cut authorized. 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: Main HALF PLAN source-local chain and cap geometry only; compass side and building registration unresolved. Partial timed visual review: Area-way coping detail at lower right; detail-local dimensions and construction labels only.

Highlighted reading: +7′0″ along W3 width axis. Supplies two mirrored rail axes, each 7 feet from the entrance centerline, and the stair-following relationship.

Signed rail-axis offset from entrance centerline

+7′0″ along W3 width axis

7 ft

The pair is symmetric; positive-X is a canonical-coordinate label, not a historical east/west mark.

IMG_1202 · sheet-W3 · Locate on drawing ↗

Drawing notation: CENTER LINE OF ENTRANCE; Main entrance stair plan

Supplies the provisional canonical stair centerline, run axis, and endpoint registration.

Drawing notation: HALF PLAN; CENTER LINE OF ENTRANCE; 7'-0"; BRONZE RAIL; SEE DETAIL SH. 213

Supplies two mirrored rail axes, each 7 feet from the entrance centerline, and the stair-following relationship.

IMG_1087 · sheet-W213 · Locate on drawing ↗

Drawing notation: HANDRAIL / MAIN ENTRANCE STEPS; DOUBLE RAIL; MODEL NO. 10; 2'-10"

Supplies the printed rail height and local fabrication identity; it does not supply the project path.
