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.

BALUSTRADE WALL AT GRADE

Sheet number unresolved

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.

Highlighted reading: ELEV. 92.75. 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.

Sheet number and issue date
Main entrance stair tread count, run, rise, landing depths and nosing
Main entrance overall stair width and exact plan registration
Continuous numeric sidewalk profile through the central entrance field
Sidewalk clear width, curb width/height and curb-to-property-line offset
Retaining-wall thickness, batter, footing dimensions, coping profile and reinforcement
Flagpole overall height, shaft/base dimensions and exact plan offsets
Printed chain terms that remain too soft to read reliably
Broadway, Madison and Sixth Street elevation chains outside the selected witness
Construction/as-built and present-day correspondence
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
Main-right chain endpoint verification
Companion plan correspondence and world orientation

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.
