Supported by 4,675 steel - reinforced concrete columns , this type of construction not only served the Donnelly well , it also provided the perfect infrastructure for future tenants . To further the building 's support structure , reinforcing bars , normally laid perpendicular , were laid at various angles enabling the floors to bear loads of at least 250 pounds per square foot . Current major tenants of the building include the Chicago Mercantile Exchange , Telx , Equinix , Steadfast Networks and Qwest . Exterior ornaments depict symbols of printing history .
