Direct answer

77 West Wacker is a downtown Chicago office tower completed in 1992. Current public sources identify Transwestern as manager and CBRE as leasing agent. A tenant platform and a 6,000-pound freight car are publicly described, but current dock, move, COI, contractor, fee, and approval rules remain unresolved.

Canonical identity

The building identity and public management/leasing relationships are resolved. Published sources disagree on floor, area, and parking counts, so Factum keeps those claims separate and does not infer a dispatch rule from a platform feature or marketing statement.

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.

Tenant platform

Public sources describe work orders, visitor registration, communications, conference-room reservations, and freight-elevator reservations. These are capability claims, not proof of permission or availability.
