River Main Building

Engineer of Record for a 29,400 square foot, five-story, mixed-use building on the river in Naperville, IL. Spread foundations on an aggregate pier soil improvement system support a steel beam and precast hollow core plank floor system. The fifteen-foot cantilever of the second floor over the adjacent River Walk culminates in outdoor dining on the fifth floor. Heavily reinforced masonry shear walls provide lateral restraint within the narrow aspect ratio of the building.
