300 East Randolph

Five-time recipient of BOMA’s Office Building of the Year TOBY Award and three-time winner of BOMA’s North Central Region TOBY Award, 300 East Randolph is comprised of an estimated 8,000 pieces of structural steel and 12,000 yards of concrete. Directly centered at its base are Ellison balanced doors that provide a marquee entrance to this 57-story Chicago wonder.

Officially called the Blue Cross Blue Shield Tower, the entrance to this immense structure features narrow stile tempered glass doors. The glass façade that covers the exterior needed a fitting entryway that matched its aesthetic. The central Ellison double-doorway, located between two revolving doors, achieves this and is equipped with PowerNow automatic opener technology.
