Which sequence correctly describes the removal of temporary bracing from a panel?

• A. Engineer clearance; site checks; remove top brace; remove bottom; relocate
• B. Engineer clearance; site checks; remove bottom; remove top; relocate
• C. Engineer clearance; site checks; release bottom connection first; then remove the top brace; relocate
• D. Engineer clearance; site checks; remove both braces at once; relocate

Answer: (C)

Staged removal of temporary bracing after engineer clearance and site checks is essential to keep the panel stable during dismantling. The bottom connection should be released first, which safely reduces restraint from the bottom while the top brace still holds the panel in place. This creates a controlled step in which movement is kept under control rather than letting the panel become unconstrained all at once. After the bottom is released, the top brace can be removed with a remaining constraint from the still-attached bottom, and then the panel can be relocated. Removing both braces at once or removing the top first would remove restraint too quickly and increase the risk of sudden movement or tipping, so those approaches are not appropriate.
