Which Construction Type is referred to as Ordinary?

The term "Ordinary" in the context of construction types typically refers to Type III construction. Type III construction is characterized by the use of non-combustible materials for the exterior walls, while the interior can be constructed with wood or other combustible materials. This combination allows for a balance of structural strength and economic viability, making it a common choice for various building types such as commercial buildings and apartment complexes.

This classification is important in determining fire resistance requirements and other building codes, as Type III structures are at a lower risk of early collapse due to fire than fully combustible structures, yet still present greater risks compared to entirely non-combustible types, such as Types I and II. Recognizing the preeminence of Type III or "Ordinary" construction helps professionals apply proper safety measures and compliance protocols during design and construction phases.
