20% provisional source coverage
USE BOUNDARYNot verified · Not dispatch ready
AMA Plaza is the Mies van der Rohe tower at 330 North Wabash, also known historically as IBM Plaza. A 2024 Illinois court order distinguishes the tower from the adjacent 401 N State parking garage.
Canonical identity
This Public Seed resolves the tower's aliases and boundary against an adjacent garage, publishes 2023 City reporting facts, and keeps current ownership, title and operational authority explicitly unknown.
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.
Tower and garage boundary
A 2024 Illinois appellate order describes AMA Plaza as the office-and-hotel tower at 330 N Wabash and the abutting 401 N State property as a separately leased parking garage. They are not merged in this record.
Court order dated January 22, 2024; reviewed August 16, 2026Aliases and vintage
Institutional architecture evidence identifies 330 North Wabash as AMA Plaza and IBM Plaza and dates completion to 1972; the City row uses 1971. Both remain source-specific.
Sources reviewed August 16, 2026Operating status
No current access, loading, freight, visitor, security, safety, emergency or contractor procedures were verified.
Explicit unknown as of August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Is AMA Plaza the same as IBM Plaza?+
Yes. Institutional architecture and City evidence link AMA Plaza, 330 North Wabash and the historic IBM Plaza name to the same tower.
02Is the 401 N State parking garage part of the same building?+
No physical-building merge is made. A 2024 court order describes it as an abutting, separately leased property, even though both sites are subareas of one planned development.
03Who currently owns or operates AMA Plaza?+
Current recorded title and receiver or operator authority were not verified. A 2024 court statement and later foreclosure reporting are retained only with their dates and limits.
04How can I improve this record?+
Submit an authoritative public URL or dated official document and state whether it may be displayed publicly, used only for verification, or retained privately. Contributions enter evidence review and never overwrite canonical claims directly.
