River House at Bridgewater Place soars 34 stories and 406 feet tall over the downtown Grand Rapids skyline. It’s the tallest building in Grand Rapids and the second tallest concrete frame building in Michigan.
Kent Companies assisted in the planning and development of the structural model for the 500,000 square foot concrete structure. Several first-time, innovative systems were utilized on this project.
On level six, immense concrete girders were required to transfer building loads as the tower perimeter stepped in. The girders included staged post-tension reinforcement, and were tensioned in multiple phases during construction to support the increasing weight of the structure as it rose— a first for West Michigan.
To increase the stiffness of the structure and reduce sway, several shear walls incorporated vertical post-tensioning— a first for the state of Michigan.
Kent brought in a special “TLS elevator” to move the unique, hybrid shoring system they developed from floor to floor—a first for the United States!
As a result of our work, innovation found a home in downtown Grand Rapids.
