CIAC Curtain Wall Anchor Safety Allegations

A certified architectural glass technician told the board the contractor installed the CIAC curtain wall with quarter-inch Tapcon screws instead of the manufacturer-required half-inch grade 5 structural bolts — a 90% strength reduction — and asked for a full anchor inspection, replacement of non-compliant fasteners, and contractor accountability.

During the second comment period he passed around physical samples of the quarter-inch screws used versus the required half-inch bolts so commissioners could feel the difference, stressing the issue is about the county getting what it paid for.
