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.

Nominal footing envelope only; source audit state: checked-master-crop-single-reader. On the actual C4/Madison plan, the labeled footing centerline lies above the steel-column centerline. Page-up is south/−Z. This sign is read on the actual plan, not transferred from the detached typical diagram.

Nominal footing envelope only; source audit state: checked-sign-on-plan; magnitude-reused-from-W409-audit. W409 establishes E as footing C.G. to steel-column C.L. and C4 suffix b; it is not the base-plate offset E′.
