What defines Type I building construction?

Type I building construction is characterized by the use of fire-resistive materials. This type of construction is designed to withstand fire for an extended period due to the noncombustible materials used in its structure, such as concrete and steel. The primary focus is on limiting the spread of fire, thus enhancing safety for occupants and providing more time for evacuation or firefighting operations.

Because of the materials used, Type I buildings can also support larger amounts of weight and are generally used for high-rise structures, commercial buildings, and those that need to comply with strict fire safety codes. Understanding the significance of fire-resistive construction is crucial for incident safety officers, as it influences strategies for risk assessment and evacuation plans in emergencies.
