Located just meters away from the Chicago River to its east and a century-old railway to its west, 150 North Riverside is a 54-storey office building that features 136 010m2 of leasable space. A signature component of the building is the core-supported structure, which was required in response to the constraints of the site. This innovative solution resulted in the tower’s dramatic form and enabled its footprint to have an area 70-percent smaller than the typical floors above.

Structural system
Designed as a typical office building from level 8 through level 54, the core-supported plan employs an efficient, yet complex, transfer truss system to shift the load from its exterior columns to be supported on its concrete core. The core rests on a 3m-deep concrete mat supported on a collection of 16 rock-socketed caissons below, each with a 3m diameter.
ArcelorMittal Steel
Constructed using 2,530 tonnes of ASTM A913 Grades 65 and 70 wide-flange shapes, these products not only enabled the design of a more efficient structure, but they also contributed to simplification in the fabrication and erection of the complex elements in this system. Benefits include:
ArcelorMittal Technical Support
Working closely with the structural engineer and fabricator, ArcelorMittal’s technical support team consulted on value engineering propositions that enabled a 6% total savings in the weight of the structural frame and resulted in this tower being first in the world to employ the world’s largest structural shapes: W36x925 and W14x873 sections.
