The project consists of a 25-story tower and two four-story "garden wings." All of the exterior cladding is Bethel White granite, the majority of which is being pre-assembled on galvanized steel strongback frames by Kepco+, the stone assembly and erection contractor for the project. According to Marlin Landry, vice president and Grand America project executive for Kepco+, a total of 2,800 stone-clad metal truss panels are being used for the project, totaling 175,000 square feet of materials. Additionally, 80,000 square feet of Bethel White granite is being handset.
The nominal size for the handset stone units is 1 foot, 3 inches x 2 feet, 6 inches, and the pieces are installed in a running bond pattern. A typical pre-assembled panel is 9 feet tall x 10 feet wide, and stone sizes are 2 feet, 6 inches x 5 feet. Corner pieces are 16 feet long x 4 feet x 9 feet, and in many locations, the stone has to span around sheer concrete walls at the corners.
