In Type I construction, which characteristic is typically observed?

• A. Structural members have little or no fire resistance
• B. Timbers provide for structural stability
• C. Roofs are extremely difficult to penetrate
• D. Ease of Ventilation

Answer: (C)

Type I construction is fire-resistive, built with noncombustible materials and protected structural members to resist heat and flame for a specified duration. Because the roof assembly and framing are designed to resist Fire exposure, flames and heat have a tougher time penetrating the roof, making it difficult for the fire to breach this part of the building quickly. That’s why the characteristic observed is that roofs are extremely difficult to penetrate. The other options conflict with Type I design: it does not rely on timber for stability, it features high fire resistance rather than little fire resistance, and ventilation ease isn’t a defining trait of this construction type.
