Pipe braces are provided by which party for temporary support of tilt-up panels?

• A. Structural engineer
• B. Crane operator
• C. General contractor
• D. Owner

Answer: (C)

Pipe braces provide temporary support to tilt-up panels during erection, keeping the panels steady and plumb as they are raised and before permanent connections and braces are in place. The party responsible for supplying and coordinating these temporary supports is the general contractor, who manages temporary works on site and ensures the braces are available and installed according to the engineer’s design. The structural engineer designs the bracing system and its capacity, but does not typically supply or install the braces on site. The crane operator handles lifting operations, not the provision of temporary bracing. The owner may specify requirements, but the day-to-day provision of pipe bracing for erection falls to the general contractor.
