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.

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.

This is a local design-grade point, not a uniform sidewalk elevation or a registered Blender world-coordinate station.

Drawing notation: EL. 83.14 AT SIDEWALK; HALF PLAN

The leader touches the lower sidewalk/step-approach line near the page-upper side of the drawn half. This point is separated in plan from the EL. 83.26 witness near the entrance centerline; their 0.12-foot difference is not a measured cross slope.
