McCarthy, who has self-performed the concrete work completed the final pour of the 126 structural post-tensioned garage deck pours. Over the course of construction, an additional 14 pours were completed for the structure’s circular concrete helix entry ramp.

Construction of the $121.7 million parking structure began in December 2008 with the project team pouring one deck every other day. In all, McCarthy has logged more than 300,000 man-hours of self-performed concrete work.

“The key to achieving the aggressive project schedule was constant communication between all parties and innovative scheduling,” says Ryan Heeter, McCarthy project director. “Through the utilization of multiple sets of formwork, specialized crews were able to work in tandem on different elements of the project which ultimately sped up construction.”

Located just north of the new Terminal 3 building, the eight-level, 6,000-car parking structure is one of the largest parking facilities in the U.S., spanning a footprint approximately 270 ft wide by 1,024 ft long. In addition to providing spaces for employee parking, valet parking and both short and long term public parking, the project also includes construction of an 11,275-sq-ft, single-level office building, toll plaza and roadway for passenger pickup and drop off.
