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.

Title Grilles For Main Floor Windows

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial first-pass review of public/archive/drawings/complete-upright/IMG_0989.webp. Access-image normalized coordinates are unrotated derivative coordinates; rotationDegrees records clockwise correction needed for readable text. No model geometry authorized by this evidence. Partial timed visual review: undefined Partial timed visual review: Source-local depicted assembly or specification only. No installed quantities, accepted floor geometry or model placement inferred. Partial timed visual review: Depicted type/component, shop order or source-local assembly only. Components and grille order quantities do not create installed fixtures or establish electrical outlet-to-type assignments.

Highlighted reading: EPN 9/7/32. Selected visible source evidence; partial review. Applies only to depicted assembly, not whole building.

Unresolved extraction work

all small dimensions and marginal notes
full-sheet completeness and companion reconciliation
floor/room registration where not explicitly printed
Installed instances, quantities and source-to-building registration remain unestablished.
Complete dimensions, machining profiles, companion sheets and governing revision authority remain open.
Remaining fine dimensions and handwritten revisions require targeted higher-resolution evidence
Companion registration and physical instance mapping remain unresolved
Remaining fine fractions, outline profiles, machining endpoints and marginal handwriting require targeted master review.
Full companion and revision authority audit remains open.
Installed instance quantities, room/floor placement, hosts and source-to-building registration are unestablished.
Date reused; no revision/approval authority inferred.
Printed cells blank. Reused prior explicit blank observation; blank is not zero.
Rivets,openholes,end&edge,spacing,paint blank. Prior detail-metal blankfinding reused; no generic defaults.
Known identifiers reused; fine made-by/traced-by/date blanks not completely transcribed.
Partial roster cannot establish all31locations or physical registration.
