Exterior walls and structural members that are made of approved noncombustible or limited‑combustible materials and interior structural members constructed wholly or partly of wood define which construction type?

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

Answer: (C)

The main idea is matching construction types to material combinations. The description fits Type III, ordinary construction: exterior walls and the structural frame are built with approved noncombustible or limited‑combustible materials, while interior structural members are wood. That exterior noncombustible shell provides fire resistance, but the interior uses wood framing, which is characteristic of ordinary construction. It differs from Type I and Type II, where interior structural members are noncombustible throughout, and from Type IV, which centers on heavy timber interior members. So the described configuration aligns with Type III.
