ICC Special Inspector

Special Inspectors are highly specialized and often work for private engineering or testing firms. They are required by the International Building Code (IBC) to oversee critical structural elements like reinforced concrete, structural welding, or masonry. They ensure that the specific materials and methods used match the engineer’s high-stress designs.
