What type of Type V construction no longer uses full dimensional lumber?

• A. Standard Platform
• B. Legacy Platform
• C. Modern Platform
• D. Lightweight Platform

Answer: (B)

In Type V wood-frame construction, platform framing is a common way to build walls and floors, and over time the terminology has evolved to reflect how the framing materials are chosen. The option described as the Legacy Platform captures the approach that has moved away from using full-dimension lumber toward lighter, engineered members. This shift to engineered components—like LVLs, I-joists, and other engineered lumber—reduces the reliance on traditional 2x lumber in the framing and reflects modern construction practices. That’s why this option is the best fit for a type of Type V construction that no longer uses full-dimensional lumber. The other terms describe different framing philosophies or historical contexts that don’t specifically highlight this material shift in the same way.
