54-story, 116,129-m² (1,250,000-ft²) Class A office tower on an extremely challenging site adjacent to the Chicago River and active Amtrak rail lines. In response to the multiple site challenges, the building features an innovative, tapered superstructure design to create a footprint equal to just 30 percent of the tower’s floor area. Building accelerations are managed with 12 liquid mass dampers, and the project includes many innovations and engineering "firsts," including the development of a thin concrete central building core structural system; use of the largest rolled steel sections in the world; design of a high-capacity primary foundation system using half as many support pilings; and many more.
