Why is it important to classify a building by its type of construction?
It is essential to correctly classify a building by its type of construction to account for the response that a building will have to a fire that occurs within the building as a result of the occupancy it serves. The building code requires that every building be classified as one out of five possible types of construction.
What are the materials used in building?
In the United States, buildings are generally constructed of one of a few types of materials: concrete, steel, masonry or wood. While each of these materials with the exception of wood are considered non-combustible, each material has methods of construction that lend themselves to being more or less fire-resistant.
What is type IV construction?
Type IV A/B/C - Mass timber construction, allowing mid-rise and high-rise construction from wood products. These types of construction will be found in the next edition of the building code, and earlier in some states.
What determines the allowable floor area of a building?
The Type of Construction directly affects the amount of allowable floor area that a building may have. Table 506.2 shows how the allowable floor area varies depending on the sprinkler system installed, the number of stories the building has and the type of construction assigned. This table can either be used to analyze if a design correctly:
What is a type III roof?
Type IIIA and IIIB - Non-combustible exterior walls with a combustible (i. e., typically wood-framed) roof requiring either low or no fire resistant construction. Construction of this type is often either tilt-up warehouse type of construction with a wood subdiaphragm type roof. Type III construction has also become more common in mid-rise multifamily construction, using fire-retardant treated wood for exterior wall construction.

What is a type III building?
Also known as brick-and-joist structures, Type III buildings consist of either tilt-slap or reinforced masonry walls. These materials are non-combustible. That is to say, some of the interior structural elements (frames, floor, ceilings, etc.) are made with wood or combustible materials. This kind of construction can apply to both old and new buildings. Old buildings will generally contain conventionally framed roofs, while newer units are typically built with lightweight roof systems.

The International Building Code ( IBC) governs the materials, systems, and assemblies used for structural fire resistance and fire-resistance related-construction. This is the resource we use to determine fire resistance ratings.
What type of building is the most combustible?
Type V buildings are the most combustible construction type on this list. It is the only category of construction that allows combustible exterior walls as well as combustible structural members on the interior. Frames, walls, floors, and roofs are made entirely or partly out of wood. These building elements are cheaper to develop and increasingly common in the construction of single-family homes and garages.
What type of construction is ladder crew?
Ladder crews have different procedures in place for different building types. When it comes to Type I construction, firefighters must be aggressive in securing stairwells and evacuating victims from the structure. With Type II construction, firefighters may consider opening skylights or resorting to natural ventilation. Depending on the roof system, they may also rely on similar ventilation operations for Type III and Type IV construction. Type V construction requires other alternatives, including but not limited to positive-pressure attacks.
How thick are structural beams?
Structural wood supports such as columns, beams, and girders must be at least 8 inches thick. Heavy planks for roofs and floors must be at least 6 inches thick. Type IV buildings have noncombustible exterior walls and interior elements.
