Which construction type is defined by all structural components being combustible, sometimes with an exterior brick veneer?

• A. Type II - Non-Combustible
• B. Type III - Ordinary Construction
• C. Type IV - Heavy Timber
• D. Type V - Wood Frame Construction

Answer: (D)

All structural components being combustible is the defining feature of wood-frame construction. In this type, the entire load‑bearing framework—studs, joists, beams, and columns—is made from wood or other combustibles, while an exterior brick veneer is only a non-load-bearing finish. That combination fits Type V—Wood Frame Construction—perfectly, since the structural system is entirely combustible even though the exterior may appear brick-like. Other construction types rely on noncombustible framing (like steel or concrete), or have exterior masonry with interior elements that aren’t fully combustible, or use large timber without calling it wood-frame, so they don’t match the given description as precisely.
