You're reviewing plans showing #4 rebar at 12 inches on center in both directions for a residential foundation wall. The wall is 8 feet high and 8 inches thick. What CBC requirement might be violated?
Correct Answer
B) Maximum spacing requirements
CBC typically requires closer spacing for foundation wall reinforcement, often 6-8 inches on center depending on wall height and soil conditions, making 12-inch spacing potentially inadequate.
