Peloza formed and cast a complicated set of stairs. Colored, stamped, and cantilevered, each riser and return was smaller than the one preceding. With the help of two of his employees, they formed the stair risers to include 2 ½-inch cantilevers with 3 ¾-inch insets and 4-inch cantilever faces. They also inserted “snapped edge” stone patterned formliner pieces on the vertical surfaces. After filling the forms and vibrating the concrete, they stamped the treads with a slate pattern. When the forms were stripped the following day, the finished work was cleaned and sealed.
