The Skyscraper Thrill Ride is an amusement park ride in Myrtle Beach. The ride features a giant propeller consisting of two arms that spins guests in a full circle. Four riders, two on each arm, sit in open cars on opposite ends of the propeller. The arms of the propeller quickly rotate spinning riders at speeds of up to 55 mph. At its highest point, riders are upside down 160 feet above the ground. WPC, A Terracon Company, was retained to perform geotechnical and construction materials engineering and testing services for this project. WPC performed a geotechnical exploration at the property to provide recommendations concerning the design and construction of the ride foundation. We provided recommendations for support of the ride with micropiles utilizing grout-injection anchors, as well as an alternate mat foundation.
