The case study provides a description of design requirements and installation procedures for an Impressed Current CP system for the Bok Tower

Bok Tower, is a masonry-encased steel framed building with marble and coquina siding. The coquina brick used to cover most of the tower exterior is a porous brick made of crushed seashells and similar material. Corrosion of horizontal structural steel members caused the coquina brick façade and underlying masonry to separate from the tower. The root cause of corrosion was found to be ingress of moisture through the porous coquina brick and from openings in the top of the tower
