Abstract:
Q. When inspecting bar placements, I’ve been confronted by contractors that argue that bars can be placed as far as 1 to 2 in. (25 to 51 mm) beyond the specified cover. In other words, they say that the tolerance on cover only limits the minimum distance from the bar to the surface of the concrete. I argue that a cover tolerance of 3/8 in. (10 mm) means the bar is required to be no more than 3/8 in. (10 mm) closer or further from the surface than the specified cover. Is that correct?
