Riverfront development that includes a 52-story, 120,774-m² (1,300,000-ft²) office tower, 6,070-m² (1.5-acre) public plaza, and 4 above-grade parking levels along the Chicago River in the West Loop area. The plaza, which contains ample seating areas, large trees, and a spacious assembly lawn, spans directly over six at-grade active rail lines as well as a below-grade Chicago Transit Authority line. A solution of elevated precast concrete bulb-Ts supported on concrete walls and steel piles provided needed railroad clear spans of up to 135 feet (41 meters). Loads for the office tower, which is directly over a below-grade commuter line, were directed to a series of deep transfer girders supported on rock caissons that straddle the transit line.
