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.

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial timed visual review: Partial sequential 1000px JPEG65 locator review of public/archive/drawings/complete-upright/IMG_1206.webp after OCR/catalogue and reports. Actual clockwise reading rotation 0 degrees. Coordinates normalized access-image before rotation. No full-region extraction/modeling claim. Partial timed visual review: Additive bounded follow-up; coordinates normalized to unrotated access raster. Original plan/topology records retained. No model acceptance or complete-sheet claim. Partial timed visual review: Bounded text-first follow-up; ten sequential inspections total across nine derivatives including one W-6 same-source core crop. No accepted physical geometry. Existing verified readings omitted. IMG_1209 uses prior closeout text only. Partial timed visual review: Access ceiling note and master crop inspected; master reading orientation 270 degrees. Pit crop missed label and produced no depth reading. Partial timed visual review: undefined Partial timed visual review: Source-local partial review; no physical coordinates accepted. Partial timed visual review: undefined Partial timed visual review: Text reuse only: prior first-floor close-up package already contains selected heights/dimensions; no visual review or count-chain duplication.

Highlighted reading: POST OFFICE WORK... / CEILING HEIGHT18'-3". High-resolution crop of master rotated90 closes the candidate3. Named work-space note only; precise regional extent and lower lookout ceilings remain unclosed.

Unresolved extraction work

Partial locator only: review every remaining region, note, schedule, dimension and companion detail
Reconcile drawing originals and annotations/revisions independently
Register stable physical instances and establish installed quantities/geometry
Every remaining dimension, schedule, callout and companion detail needs region review; no accepted physical/world geometry.
Source-local applicability, construction thicknesses, complete object inventory and as-built correspondence remain unresolved.
All unreviewed local dimensions, exact faces/jambs, room applicability, schedules and companion details remain pending; no full-image extraction claim.
Ceiling final digit remains unresolved
Scale-pit depth and complete fixture footprint
All remaining plan regions and companion details
Exact installed quantities and type-to-instance assignment
Rough/finished/structural endpoint classes, complete host outline and source-to-building registration
Governing original/revision and companion-detail authority; no accepted physical geometry
All uninspected source regions, notes, schedules and companion details; whole source remains partial
Accepted finish/rough/structural endpoint classes and source-to-building transform absent
All physical construction layers, exact material limits, installed quantities and as-built correspondence unresolved
Remaining fine chains, schedules, callouts, revisions and companion details require review; exhaustive extraction not certified
Classified finish/rough/structural faces, closed boundaries and source-to-building registration
Original/revision authority, companion details and as-built correspondence
All unreviewed regions, notes, schedules and callouts; no whole-source completeness
Second-witness candidate uses a different target identity than verified room record; not automatically confirmed. Broad geometry placeholders remain open.
Accepted source-to-building transform and like-for-like finished/rough/structural face classification
Exact closed slab opening, landing perimeter and headroom
Construction/rail/nosing detail and revision/as-built reconciliation
All remaining unreviewed regions, notes, schedules and companion details
