Best Landscape/Urban Development Winner St. Pete Pier

During preconstruction of the Pierhead building, the team discovered that dead load of the shoring and the live load of the concrete placement process combined to be nearly five times greater than the load the marine structure could support. In response, Skanska enlisted McLaren Engineering Group and leveraged the experience of other team members, including Icon and Skanska’s Self Perform Operations group, which were the concrete trade partners for the project. Together, the team designed and constructed a grillage system—consisting of 37 temporary H-14 piles approximately 100 ft in length driven into the seabed—to hold the framing of the building up off the marine pier to isolate the building loads away from the marine structure. The upper grillage consisted of W-24s in one direction and W-12s in the other.
