River East Center

Chicago, IL

Case’s specialty construction services combine to launch, top-down/construction of a major mixed-use project in downtown Chicago.

The size of this two city block site allowed installation of a 1,600 lf concrete diaphragm slurry wall to 70’, while 143 large diameter belled caissons were being drilled to depths of 100’. Extension and encasement of the upper caisson shafts set the stage for top/down construction. At the same time, a driven sheet pile cofferdam encircled the tower core where bottom-up construction of this time-critical area proceeded independently from the rest of the site work. Superstructure and substructure work then continued concurrently (up and down) achieving substantial cost and time savings.
