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.

Public-source review completed August 16, 2026Questions this record answers
Each concise answer includes the same caveats shown elsewhere on the page.
01Why does the source record say MarOuette Building?+
City, federal, owner and brokerage sources converge on Marquette Building; the census spelling is retained only as source provenance.
02Is the building open for public tours?+
The owner site describes a free lobby exhibit and asks groups to coordinate in advance; current building protocols must still be followed.
03How can I correct or enrich this record?+
Submit an authoritative public link or dated official document and state whether it may be displayed publicly, used only for verification, or retained privately. Tenant handbooks, dock and freight guidance, move rules and COI packages enter evidence review and never overwrite accepted claims directly.
