Which construction type is defined as fire resistive with protected noncombustible or limited combustible materials?

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

Answer: (C)

Type I construction is fire-resistive and uses noncombustible or limited combustible materials that are protected with fire-resistance rated assemblies. This protection helps keep structural elements from failing during a fire, providing the highest level of fire resistance among common construction types. In practice, you’ll see protected steel or concrete members and fire-rated barriers surrounding them. Other types differ: Type II is noncombustible but not necessarily fire-resistive in the same protective sense; Type III has noncombustible exterior walls with interior elements that can be combustible; Type V is fully combustible wood framing.
