Canonical identity
This Public Seed connects 550 West Washington to its public building identity, benchmark context, current property-management contacts, amenities and dated transaction reporting while preserving parcel, title, measurement and authorization boundaries.
Area claims stay separate
Gross, rentable, and office area are not interchangeable. Factum stores each measurement with its source meaning instead of choosing a convenient single number.
What public guidance supports
These are sourced research answers, not permission to enter, reserve, submit, or dispatch. Current affected-party authorization remains required.
Measurement boundary
Public sources show 16 or 17 floors and multiple source-scoped area figures; Factum does not collapse them into one verified measurement.
