Which statement about Lightweight Panelized Construction is true?

Which statement about Lightweight Panelized Construction is true?

• A. Joists are 24" on center
• B. Beams are 6' apart
• C. It is never used in Tilt-Up buildings
• D. Purlins are 10' on center

Answer: (A)

In lightweight panelized construction, the structural members are designed to be efficient and quick to assemble, and joist spacing around 24 inches on center is a common standard. This spacing aligns well with typical panel sizes (often about 4 feet wide) and supports a lighter floor system while still providing adequate load distribution. It simplifies on-site installation, reduces waste, and keeps the system relatively lightweight, which is a hallmark of panelized construction. The statement about joists being 24 inches on center is the best fit because it reflects that practical, widely used spacing for these systems. The other options don’t align with how lightweight panelized systems are typically laid out: beams spaced 6 feet apart would create larger spans than these lightweight systems are usually designed to handle; purlins spaced at 10 feet on center are generally too far apart to reliably support roof loads in such constructions; and it’s not accurate to say this approach is never used in Tilt-Up projects—panelized elements can be incorporated in Tilt-Up buildings, so that claim isn’t correct.
