Which type of construction is referred to as fire-resistive construction?

Fire-resistive construction is characterized by its ability to withstand fire and provide barriers that inhibit the spread of flames and smoke, allowing for increased safety during a fire event. Type I construction is typically made of non-combustible materials, such as reinforced concrete and protected steel, which can effectively resist fire for extended periods of time. This type is often used in high-rise buildings and other structures where fire safety is a critical concern.

The materials used in Type I construction ensure that structural integrity is maintained even when exposed to high temperatures, which is essential for allowing occupants more time to evacuate and for fire services to control and extinguish the fire. The fire-resistance ratings associated with Type I construction can vary but are generally much higher than those of other construction types. The use of fire-resistive construction is a critical aspect of building codes and safety regulations, underlining its importance in fire prevention and safety management.
