At McCormick Place, start the labor brief with the marshaling-yard slot and the building receiving the freight. Its exhibit footprint exceeds 2.6 million square feet across Lakeside Center plus the North, South, and West buildings. A single level accounts for 1.2 million square feet. That scale does not justify a building-wide mass call.

Phase workers by truck arrival, dock, hall, and task; include the freight contact, staging point, equipment requirements, and release criteria for each wave. If move-in crosses connected buildings, publish separate call locations. Freight timing from the marshaling yard controls setup and breakdown labor; the public opening does not.
