Riverside building rendering

150 N. Riverside Chicago

At 150 North Riverside in Chicago, a new 54 story office building is being constructed. It will include a 1.5 acre public plaza and green space over a parking garage, with an existing rail line passing below the parking garage. What makes this project unique is the lack of land available for carrying out construction.

To construct the building, much of the construction initially needs to be done from barges on the river. J3 is engineering the parking and plaza area that will be used as a staging area for constructing the tower.  J3 Engineering Group is working with a precaster to provide precast engineering and drafting using Revit and specialty precast software to engineer the plaza and parking garage over active rail lines.  Since the rail lines are active, the schedule on this project is incredibly important.

We used prestressed bulb tee bridge beams as the main structural support, due to their capacity to hold high soil loads as well as the heavy equipment needed for construction. Precast walls, beams, and double tees will then form a single level parking garage with a landscaped park on top. J3’s experience in prestressed concrete and Revit along with the ability to handle complex engineering calculations is a great asset to mitigating schedule delays.
