900 Randolph

Overview

Located in Chicago’s West Loop, 900 Randolph pushes the boundaries of the neighborhood’s typical low-rise design and height. Standing nearly 500 feet, the slender 43-story residential tower includes nearly 300 apartment units and a five-story podium with residential units along the street front as well as nearly 140 parking stalls, retail space, an amenity deck and access to public transportation. We provided structural design services to Morris Adjmi and Stantec for the high rise.

Highlights

• The structure's unique core layout uses an exterior corridor for the concrete core wall in order to avoid fin walls that would constrain unit layouts.
• The structural system is comprised of cast-in-place reinforced post-tensioned concrete floor plates, shearwalls and columns all founded on belled caissons.
• Tower columns are carefully coordinated with the parking layouts in the podium below in order to provide the most flexibility and parking stall counts.
