A Type V construction that has become the most common type of wood construction?

• A. Balloon Framing
• B. Platform Construction
• C. Post and Beam
• D. Timber Frame

Answer: (B)

The method that has become the standard for Type V wood construction is platform framing. This approach builds each floor as a separate platform, with vertical studs that run from the sill to the platform of the story above rather than from foundation to roof. That design makes construction straightforward and compatible with standardized lumber and fasteners, and it simplifies running wiring and installing insulation on each level. It also improves fire safety by containing fires within smaller, repeatable sections and makes it easier to repair or retrofit. Balloon framing, by contrast, uses long, continuous studs from the foundation to the attic, which was common earlier but is less favored today due to greater fire spread potential and insulation challenges. Post-and-beam and timber-frame are heavier timber methods used for architectural or structural reasons, not the light-frame approach that defines modern Type V construction.
