Which construction type is noncombustible and built with steel and concrete with high fire resistance?

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

Answer: (C)

Understand that fire resistance in construction is tied to both the materials used and the level of protection built into the structure. The description describes a construction that uses noncombustible materials—steel and concrete—and is designed to achieve a high fire-resistance rating. That combination is characteristic of fire-resistive construction, which is specifically built to withstand fire for longer periods and protect occupants and property. Other construction types may also use noncombustible elements but do not provide the same level of high fire resistance or may incorporate combustible interior elements or different framing approaches, such as exterior noncombustible walls with interior wood or timber, which lowers the overall fire-resistance profile.
