Type 2 construction is a term used in the field of architecture and construction to describe a specific type of building construction method. In the United States, this classification is widely used to categorize buildings based on their fire resistance capabilities. In this review, we will delve into the concept of type 2 construction, its significance in the region of the US, and its relevance in ensuring safety and durability in buildings.
Type 2 construction, also known as non-combustible construction, is characterized by the use of materials that are not easily ignited or burned. These materials include concrete, steel, and other fire-resistant materials. The primary objective of type 2 construction is to minimize the spread of fire and provide a higher level of safety for occupants.
In the US, type 2 construction is particularly important due to the stringent fire safety regulations and codes implemented across the country. These regulations aim to protect lives and property, emphasizing the need for buildings to withstand fire incidents and prevent the rapid spread of flames.
One of the key advantages of type 2 construction is its ability to resist fire for an extended period. The non-combustible materials used in this type of construction can withstand high temperatures, thus slowing down the progression of fire and allowing occupants more time to evacuate the building
Type I: Noncombustible (or limited-combustible) construction with a high level of fire resistance, typically concrete construction. Type II: Noncombustible (or limited-combustible) construction with a lower level of fire resistance than Type I, typically this is steel construction with or without fireproofing.
What is the difference between Type 2 A and Type 2 B construction?
Type IIA has a minimum of 1 hour fire resistance throughout. Type IIB, although noncombustible, has no requirements for fire resistance, unless required by other sections of the code.
What are the 4 types of construction?
The four main types of construction are: residential construction, commercial construction, industrial construction, and infrastructure construction.
What are examples of Type 2 construction?
Type II Construction: Non-Combustible
They typically contain metal floors and metal roofs with masonry or tilt-slab walls. Newer school buildings, shopping malls, and recently renovated commercial structures typically fall under this construction type.
What is a Type II structure?
A type 2 structure refers to buildings usually made of reinforced masonry, tilt slabs, and metal roofs. These are generally newly constructed buildings or remodels of old commercial structures. Schools and shopping malls are common examples.
