Drawing notation: MACHINE ROOM
Selected visible source evidence; partial locator review, applies only to depicted assembly.
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.
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: catalogue/OCR searched before sequential inspection of one <=1000px JPEG65 derivative from public/archive/drawings/complete-upright/IMG_1128.webp. Selected visible regions only, not full measured extraction. Coordinates normalized to unrotated access image; principal lettering upright. No modeling authorized. Partial timed visual review: Source-local printed evidence only; endpoint finish classes, installed locations and accepted geometry remain unresolved. Partial timed visual review: OCR and existing text packages searched before one sequential upright WebP inspection. Additive region review; existing verified properties reused, not copied. No accepted geometry or cross-floor connection. Partial timed visual review: Prior text/register/inventory crosswalk only. All numeric/notation/review history remains in canonical source records; no newly verified property or floor/shaft geometry. Partial timed visual review: undefined Partial timed visual review: Source-local detail/region evidence only. Printed type/floor applicability does not establish installed occurrences.

Plan distinguishes a lower clear-hatch projection, the drawn slab plane and overhead trap. Neither slab elevation token nor hatch outline defines installed opening thickness or machine-floor datum equivalence.
