Ordinary Construction refers to which type?

The term "Ordinary Construction" specifically refers to Type III construction. This classification is characterized by buildings that are made of both non-combustible and combustible materials. In Type III construction, the exterior walls are typically constructed of non-combustible materials such as brick or concrete, while the interior elements, including floors and roofs, often utilize wood or other combustible materials. This combination results in a building that can sustain fire for a limited duration but is still vulnerable to fire spread within the interior.

Understanding this classification is crucial for firefighters, as it informs strategies for attack and ventilation. Buildings of Ordinary Construction often present unique challenges, such as void spaces and the potential for rapid fire spread through combustible interior materials. Recognizing these features aids in efficient fire suppression tactics and enhances safety for both firefighters and occupants.
