An eye-catching linear terrazzo pattern in the lobby and atrium distinguishes this 20,000-square-foot project. In an interplay of four colors, stripes within stripes are superimposed on a large stripe of another angle and interspersed with random, abstract cloud forms, creating a sense of space and spaciousness. Epoxy mortar was chosen for the underlayment to correct an irregular substrate depth that varied from 1/16 inch to two inches.  Precast terrazzo treads and risers with exposed stringers connect the upper and lower floors while poured-in-place tread and risers flow seamlessly into the floor and wall panels that separate the upper and lower lobby.
