The Sound Transit graphics system included porcelain enamel graphics, custom shaped aluminum blade sign frames, custom cast brackets, tapered-cast base elements, and rolled aluminum logo forms. All elements of the system had to be fabricated to tight tolerances so that any bracket, hardware element, sign panel, or backer frame could be totally interchangeable system wide. CRĒO consulted with the design team to help develop precise fabrication standards that ensured that objective was met.
