Superior construction category includes which description?

• A. Noncombustible exterior walls, floors, and roof supported by metal, cement, or other noncombustible materials
• B. Frame
• C. Masonry veneer
• D. Hollow concrete block

Answer: (A)

Superior construction means the building’s main structural parts are noncombustible. The best description fits when the exterior walls, floors, and roof are noncombustible and are supported by noncombustible materials such as metal or cement. This reflects the highest fire-resistance level in construction classifications. Frame construction uses wood and is combustible, so it isn’t considered superior. Masonry veneer involves a nonstructural veneer over a wood frame, which does not meet the noncombustible, all-major-parts criterion. Hollow concrete block is masonry, but the phrase emphasizes that all major structural components are noncombustible, which the description provided specifically conveys.
