Which type of construction is referred to as Ordinary?

The term "Ordinary" construction pertains to Type III construction, which is commonly used in various building applications. This classification is characterized by exterior walls that are made of non-combustible materials, while the interior structure can feature combustible materials. This construction type provides a moderate level of fire resistance compared to other classifications.

In Type III construction, the presence of non-combustible exterior walls allows for enhanced durability and protection against external fire hazards, making it a popular choice in urban environments for commercial and residential buildings. The use of combustible materials in the interior does not significantly compromise the overall safety, provided that adequate fire protection measures are put in place.

Understanding the distinctions between construction types is crucial, particularly in fire safety and building codes. Type I and Type II constructions are entirely non-combustible, while Type V construction is characterized by its combustible materials in both the structural and exterior elements, making it less fire-resistant than Type III.
