When designers lack confidence in masonry, they may overdesign projects, making walls thicker than required. Worse, they may avoid structural masonry altogether, opting instead for building systems less dependent on workmanship in the field. By specifying inspection of critical masonry operations, such as grouting and tie placement, designers can rest assured that their plans are followed. Materials can be used more efficiently, which can mean savings for the owner. And masonry becomes a more affordable and dependable building system. A trainer of special inspectors, Don Wakefield of Masonry Information Service in Sandy, Utah, emphasizes the economic value to the owner, the person who pays for the special inspector's services. "If a 6-inch inspected wall can replace an 8-inch uninspected wall, that's saving 2 inches of masonry which can be a lot of money--in labor, as well as material." Even though a special inspector is often paid $35 to $45 an hour, "the cost advantage to the owner can be as much as four times the cost of the inspector." The larger and more complicated a masonry project, the more likely special inspection will save the owner a substantial amount of money. But saving money is only one advantage of special inspection. Sometimes architects want thinner walls for aesthetic reasons. The primary advantage of special inspection, however, is the assurance that masons won't take shortcuts or make mistakes on structural masonry projects.
