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.

Detail of Stair D and Fan Room

Sheet W224

Extraction: Reviewed · extraction partial. Typical lower stair plan and sections A-A/B-B: flight widths, numbered 9+2+9 arrangement, going, landing spans, selected materials and seventh datum. Read column reference marks 82/68, 1′4″ horizontal offset, and 9′0″ TO CL COL82 ordinate; face endpoints remain unresolved. Entry leaf size and swing, nominal 4-inch ordinary-floor partition, and offset witness semantics; no exact finished-face insertion. Stair D W224/W-6 fourth-floor placement comparison; no accepted insertion or opening polygon. Partial timed visual review: Existing W224 detailed packages reused as text only; no source inspection or new measurement. Outstanding roof/fan-room regions, rail/newel, thickness and registration retained. Partial timed visual review: Text/OCR, review-queue and prior-package audit; prior verified readings reused without duplication. No accepted geometry or building connections. Partial timed visual review: Additive selected-region review. Prior verified records reused without duplication; no accepted geometry. Partial timed visual review: Selected construction and reference-face review only; source evidence does not authorize physical geometry. Partial timed visual review: Text reuse only: preserve existing verified stair counts/width controls and unresolved endpoint classes without new visual review or duplicate numeric readings. Partial timed visual review: New section A-A local notes/witnesses do not settle the uncertain tread-material abbreviation, finish/core planes, headroom, profiles or any world-transform question. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage.
