Which construction type is known for wood as its primary structural material?

• A. Type I
• B. Type II
• C. Type III
• D. Type V

Answer: (D)

Wood-frame construction uses wood for the primary structural members—the studs, joists, and rafters form the building’s skeleton. This is the hallmark of that construction type, which is why it’s identified by wood as its main structural material. It’s the approach you see most in houses and small buildings because wood is lightweight, easy to work with, and cost-effective. The other types rely on noncombustible materials like steel or concrete for the main frame, or use large wooden members in a different category, so they aren’t described as being built primarily with wood framing.
