The five types of building construction: fireproof, fireproof, ordinary, made of heavy wood, with a wooden frame. Building construction types classify buildings according to the combustible and fire resistance of structural elements, interior and exterior. The next level covers a form of construction that was the norm for many buildings until the 19th century and that has enjoyed a revival of interest in recent years. Heavy-wood buildings have structures constructed of wood but, given the large size of the woods, they can withstand fire longer than houses with a light wood frame.
At a minimum, wooden columns, beams, and beams in heavy wood structures should be eight inches thick, while floorboards should be at least six inches thick. The greater structural mass of these wooden elements ensures that buildings will stand longer; a fire resistance of one hour is required for the structural frame. The outer walls of Type IV buildings are made of non-combustible materials. By distinguishing these building constructions into five types, you can personally decide which structure is best for a new construction.
These buildings, easily recognizable by firefighters, have wooden walls and ceilings seen in old barns, factories and churches. Building codes classify all structures, from type 1 to type 5, and this type of building reveals crucial information, such as fire resistance. However, because they use steel and metals in roof construction, type 2 buildings run the risk of the roof collapsing during a fire, due to the distortion, expansion and relaxation of steel elements when exposed to extreme heat. Knowing if a building is level I or III provides essential information when developing a strategy to control a fire and prevent it from spreading to other buildings.
Once again, these types of building construction include fire-resistant, fireproof, ordinary, heavy-wood and wood-framed materials. Because of their materials and design, type 1 buildings are considered to be the safest in the event of a fire, since they can withstand high temperatures for long periods of time. By comparison, older buildings have conventional framed roof systems and masonry walls that are not reinforced. VA type buildings are known as “protected structure buildings” and include many small, new apartment buildings.
Buildings can be classified, to choose some examples, according to their owners (for example, public or private), the materials used to construct them or their uses. Before starting any project, the contractor must review the sections of chapter 6 that are relevant to that specific building and its level in the IBC system. Although Type 3 buildings contain fire-resistant materials, their roof systems burn out quickly and their fire-cut beams pose a hazard to firefighters. Understanding how fire spreads in different buildings allows firefighters to make crucial decisions about ventilation and water.
Regardless of the project you're working on, it's imperative to understand and recognize the five types of building construction when you encounter them.
