Type 1 construction is best described as ...

• A. Wood frame construction
• B. Lightweight construction
• C. Noncombustible construction
• D. Fire resistive construction

Answer: (D)

Type I construction is the most fire-resistive building type, built to withstand fire for a defined period through fire-rated assemblies and protections around the structure, using primarily noncombustible materials. This emphasis on rated fire resistance is why “fire resistive construction” is the best description. Wood frame construction uses combustible materials and is not designed for the same high fire resistance. Lightweight construction pertains to the mass and ease of assembly rather than a specific fire-rating system. Noncombustible construction describes the materials themselves, but Type I focuses on the overall fire rating of the building as a system, not just the material.
