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.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial locator review after catalogue/OCR using <=1000px JPEG65 derivative of public/archive/drawings/complete-upright/IMG_1153.webp. Lettering upright. Regions are original access-image normalized coordinates. Locating a region does not claim full review of its fine detail. No modeling. Partial timed visual review: Additive bounded remaining-region review of upright WebP after queue, OCR and prior packages; no geometry acceptance. Partial timed visual review: Additive targeted review; source-local details only. No installed quantities, finished room geometry or model acceptance established. Partial timed visual review: Prior finish/material/fixture text findings reused; source not reopened and no duplicate properties added. Partial timed visual review: Source-local view inventory and selective notes/individual properties; repeated-photo correspondence does not establish revision equivalence, installed quantity or exact geometry. Partial timed visual review: Selected source-local properties; source remains incomplete.
