The challenge met here was to replicate original terrazzo colors and to recreate the master workmanship in century-old vertical terrazzo staircases, with ADA compliance.  Beyond duplicating treads, risers and stringers, the stairways needed rounded corners with a continuous balustrade, three stories tall. The balustrade was to be recessed with a nine-inch rounded cap to form the continuous spiral from floor to floor. These new staircases are indistinguishable from the original terrazzo throughout the school.
