Which statement about tilt-up panel framing is correct?

• A. Frames must be embedded
• B. Frames are not used
• C. Door and window frames may be embedded or cast-in-place
• D. Frames must be cast-in-place only

Answer: (C)

In tilt-up construction, openings for doors and windows are treated with flexibility: the frames can be integrated into the panel either by embedding them during casting or by casting the frame in place (or installing after the panel is erected). This approach lets the design balance precision, weatherproofing, and sequencing. Embedding frames during casting provides a tight, flush opening with less field work, but requires exact frame sizing and placement upfront. Casting in place or installing frames after the panel is raised allows easier adjustment for alignment and hardware fit, though it adds on-site installation steps. Therefore, saying that door and window frames may be embedded or cast-in-place accurately reflects the common, adaptable practice.
