What is Type 3 Construction commonly referred to as?

Type 3 Construction is commonly referred to as Ordinary Construction. This classification is characterized by its use of a combination of non-combustible materials, such as masonry or concrete, along with combustible materials, typically wood, in the structural elements. These structures are designed to provide a level of fire safety while still being cost-effective for building purposes.

Ordinary Construction is often employed in commercial buildings, such as small retail stores, where there are distinct limits on building height and area. The combination of materials makes Type 3 structures more susceptible to fire spread than fully non-combustible types, but more fire-resistant than structures that rely solely on combustible materials. Understanding this classification helps fire inspectors evaluate potential risks associated with fire spread and structural integrity during inspections.
