Which statement describes the devices necessary for lifting, setting, and bracing tilt-up panels?

• A. The method for rigging up forms
• B. The type of bolts used with coil inserts
• C. The process for bracing a slab
• D. The devices necessary for lifting, setting, and bracing tilt-up panels

Answer: (D)

The concept being tested is that tilt-up construction requires specific hardware designed for lifting, setting, and bracing the panels. Panels are cast on the ground and must be safely raised into an upright position, positioned accurately, and held steady while connections are made. This requires dedicated lifting devices attached to the panel (such as lifting inserts or eyebolts, brackets, and other embedded hardware), along with rigging like slings or spreader bars to distribute the load, and temporary bracing systems to keep the panel plumb and secure during erection and until permanent connections are in place. This set of devices is distinct from tooling for forming methods, bolt types used with inserts, or separate slab-bracing processes, which is why the statement describing the devices necessary for lifting, setting, and bracing tilt-up panels is the correct description.
