STAIR DDrawing notation: STAIR D
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.

Sixth-floor landing exceptions are excluded from default prototype.

Regularly stepped drawing supports this hypothesis, but no printed individual riser height was securely read.

Drawing notation: FINISH WALL LINE / ROUGH WALL LINE
These are separately labeled planes in the generic two-riser landing detail; neither can be silently substituted for the other.
Numeric value unresolved
Drawing notation: [fraction unresolved]
The printed fraction may resemble ¾″, but its numerator and assignment cannot be certified in this image. No ¾-inch finish thickness is adopted.
Numeric value unresolved
Drawing notation: [fraction unresolved]
Adjacent references distinguish finish wall and projecting metal wall-string/base. Do not assign the finish-layer dimension to the base projection.
Drawing notation: BASE AT LANDINGS FORMED BY EXTENDED WALL STRING
Detail explicitly titled for Stairs B, D, E.
5 in
Typical B/D/E intermediate-landing detail only; do not generalize to all room bases.
Drawing notation: 5″
Vertical dimension runs from landing top to top of projecting wall-string base, not to a room datum.
Drawing notation: REPLACEABLE SAFETY TREADS
Typical section through landing and risers for Stairs B, D, E.
Drawing notation: PANELLED RISERS
Construction/finish relationship; precise product, thickness and composition remain unresolved.
Drawing notation: ALL STAIRS HAVING NON-SLIP OR SAFETY TREADS ARE TO HAVE INTERMEDIATE LANDINGS COVERED WITH SAME MATERIAL AS TREADS
