Which construction type is noncombustible, built with steel and concrete, but with little to no fire resistance?

• A. Type 3 Construction
• B. Type 1 Construction
• C. Type 2 Construction
• D. Type 4 Construction

Answer: (C)

The concept here is how construction types relate to both the materials used and the fire-resistance requirements. Materials that don’t burn easily are described as noncombustible, like steel and concrete. But the fire-resistance rating of the structure—the hours a element or system can stand up to fire—depends on design and code requirements, not just the materials. This construction type uses noncombustible materials such as steel and concrete, so it won’t ignite, but it typically has little to no inherent fire-resistance rating built into the framing itself. In other words, the structure relies on the noncombustible nature of the materials rather than engineered fire-resistance for the framing. That’s why this type is described as noncombustible with little to no fire resistance.
