The building elements are the primary structural frame, bearing walls, non-bearing walls, floor construction, and roof construction. A Type V-B construction, the most basic, does not require a fire resistance rating for any of the building elements. Walls and framing can be built out of any materials allowed by code with Type V construction, typically wood. For the purpose of this overview, we’ll start by describing the least stringent construction Type V, and work our way up to Type I. Type V, on the other hand, is the least stringent.Įach type of construction is further described as “A” or “B.” Suffice it to say that a type B designation is basic and type A is enhanced. Building materials and practices used in Type I construction provide the highest level of fire protection. Type I is the most stringent construction for a building. You’ll want to work with them to clearly outline your needs and requirements before you get too deeply involved in the planning details. Ultimately, the type of construction drives the building’s use, occupant load, square footage, height, proximity to other structures, windows, exit placements, fire resistance, and the need for sprinklers.ĭetermining which of the five types of construction your project falls under is a key decision as part of the scoping process with your construction manager and building designer.

Secondary is the preservation of the property itself. The primary purpose of categorizing various types of construction is to establish a basic level of safety for occupants in the event of a fire. The International Building Code ( IBC) categorizes buildings into five types of construction, and each has different parameters.
