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.

Stair. A Basement 1St. & 2Nd Floors

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass sequential review of public/archive/drawings/complete-upright/IMG_1108.webp through 1000px maximum JPEG quality65 locator after OCR/catalogue and existing reports. Actual clockwise reading rotation 0 degrees. Coordinates normalized access-image before rotation. Fine blurry readings remain null; no modeling. Partial timed visual review: Source-local printed evidence only; no accepted building transform, installed quantity, or reconstructed geometry. Prior verified measurements omitted; unresolved endpoints and companions retained. Partial timed visual review: Additive selected-region review. Prior verified records reused without duplication; no accepted geometry. Partial timed visual review: undefined Partial timed visual review: Prior evidence reused as text only; no new pixel evidence or exhaustive coverage. Partial timed visual review: Bounded upright native crop; regions mapped back to normalized full reading frame corresponding to access image. Original master EXIF is stored independently and was not applied as an automatic transform.

Highlighted reading: 1ST FLOOR PLAN. Partial detail-level evidence; installed quantities and geometry not established.

Unresolved extraction work

Review fine dimensions and note text with bounded targeted crops or cleaner companion capture
Reconcile companion sheets, marks and revisions
Assign installed instance IDs and quantities; no traced geometry from locator image
Remaining dimension chains and fractional witness endpoints
Opening, wall and slab face classification
Companion W228 construction and revision reconciliation
Floor-plan registration and installed instance assignment
Independent geometry/model acceptance checks
Remaining fine fractions and complete witness endpoint classification
Material specification, fastening, profile and installed occurrence
Revision authority and companion W228 reconciliation
Floor-plan registration and independent model checking
Complete member/profile dimensions, fastener sizes, finish thicknesses and endpoint classes
Installed instance allocation, floor/terminal applicability and revision disposition
Companion W228/exposure reconciliation, source-to-building registration and independent physical checks
Complete fine chains, rail/stringer/nosing profiles, fasteners, material/finish extents and endpoint classes remain partial.
Installed quantities, closed landing/slab-opening boundaries, headroom, physical clear widths, source-to-building registration and independent checks remain unresolved.
Companion W228 and governing original/revision applicability remain unresolved; no accepted geometry or whole-source completion.
Remaining risers, treads, flight widths, landings and rail sizes across all levels.
Companion W228 and floor/finish datum classification.
Installed instance allocation and physical building registration remain unresolved.
Source-local extraction only; no geometry authoring, modeling check or whole-building acceptance.
