Q: By saying span, does the entire base of the tower need to be outside the square opening, or can a tower cut the corners of the opening. For instance if it is an octagon, is it possible for the edges of the tower base to come over the corners of the opening as long as there is sufficient space for the loading chain. (section: 3 / paragraph: b / sub-paragraph: / line: 1)
