Is also known as ordinary construction, and has exterior walls and structural members of approved noncombustible or limited-combustible materials.

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

Answer: (A)

Ordinary construction is defined by the materials used for the building’s shell and frame. In this type, the exterior walls and the primary structural members are built from approved noncombustible or limited‑combustible materials. That combination is the hallmark of ordinary construction, making it the best fit for the description. In practice, you’ll often see exterior masonry walls with a wood or light-frame interior, meaning interior structural members can be combustible, which distinguishes it from fully noncombustible types. This contrasts with the other categories: fire-resistive (Type I) and noncombustible (Type II) require noncombustible materials throughout the structure, and Type V uses wood-frame construction throughout. So the description aligns with ordinary construction, which is Type III.
