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.

Third-floor office plan

Original sheet identity has not yet been reconciled.

Extraction: Reviewed · extraction partial. Partial: Third floor plan boundaries, room identities, opening candidates and printed control chains. Third-floor outer trace reused only as a parent of the analytical registration curtain. Confirmed Stair D identity, source handedness, third-floor elevation title, and candidate C68/C82-to-perimeter alignments. Existing third-floor door topology reused only. Reused the provisional level-3 Stair E plan envelope as one input to a cross-floor median diagnostic envelope. 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: Prior verified extraction reused without duplication; selected new properties only. No full-coverage or physical geometry claim. Partial timed visual review: undefined Partial timed visual review: undefined Partial timed visual review: Third-floor source-local Men's339/adjacent janitor and service annotations. Raw0; access WebP's270-degree orientation not used. Partial timed visual review: Text reuse only: floors-2-3 topology records B/D/E only on third floor and explains access WebP rotation 270° from upright raw master. No whole plan reopened.

All unreviewed local dimensions, exact faces/jambs, room applicability, schedules and companion details remain pending; no full-image extraction claim.
Full room/opening/fixture inventory and property extraction
Exact witness endpoints, wall faces and closed polygons
Companion details, schedules and revision authority
Installed quantities, materials and accepted building registration
Exact finished/rough/structural/clear face classification and closed boundaries
Complete local dimension, door/window/type/detail inventory
Applicable companion construction, finish exceptions and chronology
Checked physical registration and installed quantities
Men's339 east-side symbols/cubicles, fine fixture keys and complete source-to-plumbing crosswalk
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
Each physical wall/room/opening still needs classified finish/rough/structural faces, closed boundaries, build-up, levels, installed quantity and checked building registration; source glyph closure does not supply these.
Exact finished/rough/structural/clear endpoint classes, closed boundaries and physical dimensions remain unresolved.
Installed quantities, construction build-up, fixture/material schedules, original/revision authority and companion applicability remain unresolved.
Source-to-building registration, datum continuity, independent checks and architectural acceptance remain unaccepted.
All remaining unreviewed notes, regions, callouts and schedules require further review.
