Wood frame construction is commonly referred to as __________ construction.

• A. Type V
• B. Type II
• C. Type III
• D. Type IV heavy

Answer: (A)

The idea being tested is how building construction is classified by fire-resistance and materials. Wood-frame construction is labeled Type V in building codes, because it uses combustible wood framing as the main structural system. This category is distinctive for houses and other structures built with wood studs and other wooden components, reflecting its more fire-prone, lighter construction compared with the other types.

To put it in context, the other classifications describe different material choices: Type I and Type II are noncombustible systems (like concrete and steel); Type III has noncombustible exterior walls with interior elements that can be combustible; Type IV uses heavy timber members. Type V is specifically the designation for wood-frame construction, which is why it’s the correct answer.
