Which of the following is a characteristic of Type III Ordinary construction?

Type III Ordinary construction is defined primarily by the construction materials and methods employed in its design. One of its key characteristics is that the structural members are typically made of noncombustible or limited combustible materials. This means that while the exterior walls may not be of heavy timber, they are often constructed from materials that, while potentially combustible, have a good degree of resistance to fire.

This classification allows for more versatility compared to heavy timber structures, which are completely comprised of heavy materials. Type III buildings often combine both combustible materials used in walls, like wood, with noncombustible elements, ensuring that these buildings remain structurally sound in the event of a fire. Such a configuration can also influence how fires spread within these structures, as the presence of noncombustible materials can help to contain fire to certain areas.

While options for wood exterior walls, heavy timber members, or limited combustible materials only in interior spaces focus on different construction types, they do not accurately reflect the defining characteristic of Type III Ordinary construction, which is the combination of noncombustible or limited combustible structural members throughout the building.
