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.

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.

37.5 ft

Display candidate only. The distinct sixth-floor witness moves the literal zero-offset candidate three feet relative to the lower-floor candidate; that shift is not accepted.

Alternate W224 photograph. Printed controls and the sixth-floor landing exception are corroborated; every candidate building transform remains conditional on explicit column and wall-face offsets.
