Park Construction Company paved the U.S. Bank Stadium floor prior to the placement of the turf. Most commonly associated with ensuring proper grading and paving of airport runways and highway projects, 3D control systems were used in the grading and paving process.
Park Construction’s Caterpillar 160M motor grader and AP1055E paver were equipped with 3D paving and grade control units. Park Construction was able to meet the NFL’s strict design standards, which called for an 1⁄8-in. tolerance for each 10-ft grid segment of the 270-ft by 420-ft asphalt paving area, with no crowns along the edge. Grading the gravel took three and a half days, and the entire paving process was completed in only two days.
