What defines the construction type?

• A. The color of exterior cladding
• B. The fire resistance rating of structural elements
• C. The occupancy type
• D. The material type used

Answer: (B)

The construction type is defined by the fire resistance rating of the structural elements. This rating indicates how long beams, columns, floors, and other load-bearing assemblies can withstand exposure to fire before failing, which directly governs how the building is classified and protected in codes. Exterior cladding color has no bearing on the structural fire-resistance design. Occupancy type describes how the space is used and related life-safety considerations, not the inherent fire-resistance of the structure. Material type alone doesn’t establish construction type, because the same material can be used in different fire-resistance designs; what matters is the specified fire resistance of the structural assemblies.
