Temporary bracing is important during erection because it provides what?

• A. Temporary bracing provides lateral stability to prevent buckling or collapse during erection until permanent connections and bracing are in place.
• B. Temporary bracing is used only for alignment after erection.
• C. Temporary bracing is decorative.
• D. Temporary bracing is optional.

Answer: (A)

During erection, the frame isn’t yet anchored together in a rigid, load‑sharing system, so slender members can bow, twist, or buckle under their own weight, crane loads, and wind. Temporary bracing provides lateral stability to prevent buckling or collapse until permanent connections and bracing are in place. It keeps the structure plumb and aligned, protects workers, and ensures that subsequent connections can be made safely and accurately. It’s not just for alignment after the fact, not decorative, and not optional—temporary bracing is a critical safety and stability measure during construction.
