Which type of construction is identified as ordinary construction?

Ordinary construction, also known as Type 3 construction, is identified by its use of non-combustible materials for the building’s exterior walls while typically utilizing combustible materials for the interior structure. This type of construction often includes masonry or brick for the exterior, which provides a degree of fire resistance due to the non-combustible nature of these materials.

Type 3 buildings are commonly found in urban areas and can include multi-story buildings such as warehouses, commercial buildings, and some residential structures. The combination of non-combustible walls and combustible interior framing creates unique challenges for firefighters, particularly in terms of how fire spreads and behaves within these structures.

Understanding the characteristics of ordinary construction is important for firefighters as it helps in assessing fire risks, planning strategies for fire suppression, and improving building safety measures during firefighting operations.
