What is the normal tolerance for the location of bends and ends of reinforcing bar?

• A. +/- 4 inches
• B. +/- 2 inches
• C. +/- 6 inches
• D. +/- 1 inch

Answer: (B)

The location of bends and ends of reinforcing bar is allowed a small, practical deviation to account for field placement variability. The standard tolerance is plus or minus two inches, which strikes a balance between being precise enough to maintain proper layout and cover, and being realistic for on-site bending, tying, and formwork shifts. If the tolerance were as loose as a few inches, you could end up with misaligned bars or inadequate cover; if it were much tighter, field crews would struggle to meet the requirement consistently. So plus/minus two inches best accommodates typical construction practice while maintaining structural expectations.
