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.
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. Selected Main Street printed elevations and chain dimensions; Main entrance and flagpole parapet dimensions; one labeled Sixth Street entrance retaining-wall/ramp section as a site-wall construction witness. 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: Interior face of parapet looking toward Main Street; page-left/right only. Raw pixel content is upright despite stored EXIF 6. New readings are independent receipts, not silent corrections to prior package.

80.04 ft
Bounded IMG_1245 site/entrance source audit; no pixel scaling or world registration.
Drawing notation: EL. 80.04
Repeated at three points on the plan's page-right wall line.
80.08 ft
Bounded IMG_1245 site/entrance source audit; no pixel scaling or world registration.
Drawing notation: EL. 80.08
Printed beyond the page-right wall line at the ramp.
The left witness runs from the inner/right face of the pier at the end of the page-left 21'-2" wall run to the pole axis. Enriches main-north-flagpole-page-left-offset-a; does not establish compass side or world station.
Drawing notation: 6'-9½"
The left witness runs from the inner/right face of the pier at the end of the page-left 21'-2" wall run to the pole axis. Enriches main-north-flagpole-page-left-offset-a; does not establish compass side or world station.
Right witness runs from the pole axis to the inner/left face of the next pier toward the entrance center. The 21'-3" segment is beyond that pier, followed by 4'-6" and 32'-6"; pole axis is not an endpoint of the 32'-6" central half chain.

92.75 ft
White printed leader to the top zone of the short page-left run. Earlier package reads 92.79; both retained. Same surface identification and revision precedence require checking.

Conflicting readings: site-main-wall-page-left-coping-elevation
94.75 ft
Pier immediately page-left of pole, not next pier on the page-right side. Earlier receipt reads 94.13; preserve both without modifying its provenance. Next pier also carries 94.75 independently.
