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.

Reserve Fdr

Printed schedule property only. Stable extraction instance represents a schedule row; installed location/floor and physical equipment identity unresolved. Yellow handwriting is not substituted for original printed rating. Review correction review-correction-20261013l-detail-mech1338b-m037: Targeted same-image schedule crop shows CLOCKS & A.F. in the final white printed MAIN SWITCHBOARD LIGHTING CIRCUIT cell. Prior Reserve Fdr transcription is not the visible lettering. This proposes a transcription withdrawal, not a historical revision choice or rating replacement.
