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.

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.
138 in
Upper B-B dimension between FIN. 6TH FLOOR and FIN. 7TH FLOOR; floor datum mapping and headroom unresolved.
Drawing notation: 11'-6"
Upper B-B dimension between FIN. 6TH FLOOR and FIN. 7TH FLOOR; floor datum mapping and headroom unresolved.
84 in
Upper A-A horizontal witness over flight; tread/nosing endpoints not classified. Do not equate this to net physical run.
Drawing notation: 7'-0"
Upper A-A horizontal witness over flight; tread/nosing endpoints not classified. Do not equate this to net physical run.
Printed TILE leader at left upper A-A wall; thickness and extent unresolved.
Drawing notation: TILE
Printed TILE leader at left upper A-A wall; thickness and extent unresolved.
57 in
Upper A-A left chain segment; surrounding fractions and witness face classification remain unresolved.
Drawing notation: 4'-9"
Upper A-A left chain segment; surrounding fractions and witness face classification remain unresolved.
Numeric value unresolved
Adjacent fractional chain glyph cannot be verified in access crop. Null preserved; no chain closure calculation.
Drawing notation: 3'-11 [fraction]"
Adjacent fractional chain glyph cannot be verified in access crop. Null preserved; no chain closure calculation.
Master crop distinguishes newel-side and wall/tile-reference stations; existing 57in and84in spans retained. Beam-centre and finish-face exact equivalence not accepted; this is an observed dimension-chain inventory.
Drawing notation: [seventh-floor chain passes wall/tile reference, beam station, newel side and return wall reference]
Master crop distinguishes newel-side and wall/tile-reference stations; existing 57in and84in spans retained. Beam-centre and finish-face exact equivalence not accepted; this is an observed dimension-chain inventory.

Numeric value unresolved
Native crop still does not securely distinguish the fine fractional suffix. Existing null retained; no difference or chain closure used.
Drawing notation: 3′11 [fraction]″
Native crop still does not securely distinguish the fine fractional suffix. Existing null retained; no difference or chain closure used.
Calculated from: stairs1012a-1112-m002
Original white printed drawing layer. Observed A-A upper-flight guard arrangement only; rail section, newel dimensions, installation and precise terminal-floor relation remain unresolved.
Drawing notation: [sloped rail with vertical infill connects elevated end newels above stair flight]
Original white printed drawing layer. Observed A-A upper-flight guard arrangement only; rail section, newel dimensions, installation and precise terminal-floor relation remain unresolved.
