Which item is provided by the general contractor for temporary support of tilt-up panels?

• A. Floor brace
• B. Lifting inserts
• C. Spreader bar
• D. Pipe braces

Answer: (D)

Temporary supports are used to keep a tilt-up panel stable after it’s raised and before it’s fully connected to the slab. The general contractor typically provides pipe braces for this job because they’re a flexible, adjustable, and easily removable system that can quickly brace the panel in place during alignment and tying of connections. Lifting inserts are built into the panel during casting by the fabricator and are used to lift the panel, not to brace it after it’s upright. Spreader bars are part of the lifting gear used to distribute the lift load during the tilt, usually supplied as part of the erector/crane package rather than as a permanent or interim support system. Floor braces may appear in some settings, but pipe braces are the standard temporary support element supplied by the general contractor.
