It has masonry-bearing walls but the floors, structural framework, and roof are made of wood or other combustible material; for example, a concrete-block building with wood roof and floor trusses.

Ordinary construction buildings have a long history of difficult fires. The joists, for example, will rest in the masonry or brick wall and may be used to support the exterior walls. We know that fire behavior is directly linked to the type of construction and the fuels invovled.

When building construction is your training topic, always start by ensuring that your crew knows and understands the fundamentals of each type of construction, as well as how each type may incorporate features from other types. Most U.S. cities are a mix of different construction types, each with their own special set of problems. Here are some pictures that show some Type III construction. The masonry walls serve both to carry the load of the building and prevent fire extension into adjoining buildings. You can find some form of it in just about any city in the country, from old schools made of hand-cut stone walls with simple beams that span the width of the building, to new strip malls with pre-cast blocks and lightweight engineered wood trusses. Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed. Just like in a balloon frame house or really any wood-frame building, Type 3 buildings feature lots of void spaces created by the construction process. Type III construction is also referred to as Ordinary construction and is very common in a great deal of our older downtown areas.
