What is Type 1 and Type 2 construction?
The major difference is that it is not protected. For example, in a Type I building we will see columns and beams covered with fire resistive spray on material as seen in the first picture. In a Type II building these columns and beams are not protected and will be exposed during a fire.
What is the difference between IIIA and IIIB construction?
Type IIIA requires 1 hour fire resistance throughout except that exterior bearing walls require no less than 2 hour fire resistive construction. Type IIIB has no fire resistance requirements, except for exterior bearing walls, which has the same requirements as Type IIIA.
What is a Type 2 construction?
TYPE II – This type of building has steel or concrete walls, floors, and structural framework similar to type I construction; however, the roof covering material is combustible. The roof covering of a type II building can be a layer of asphalt waterproofing, with a combustible felt paper covering.
What is Type C construction?
There are three types of construction, namely A, B and C, which are determined by the building’s class and rise in storeys. Type C includes buildings that have a lower risk and is therefore the least fire resistant.
What is a Type 3 construction?
TYPE III-A–Protected Combustible (Also known as “ordinary” construction with brick or block walls and a. wooden roof or floor assembly which is 1 hour fire protected).
What is construction Type 1 A?
TYPE IA (ISO 6): The main structural elements are noncombustible. Examples of these materials would be masonry and concrete. Basically, all concrete construction. Basically, protected steel construction. TYPE IIA (ISO 4): The main structural elements of the walls are masonry or concrete.
What’s the difference between Type I and Type II construction?
TYPE II– This type of building has steel or concrete walls, floors, and structural framework similar to type I construction; however, the roof covering material is combustible. The roof covering of a type II building can be a layer of asphalt waterproofing, with a combustible felt paper covering.
What’s the difference between Type 1 and Type 2?
There are three transitional varieties known that can be found with either type; 1950, 1951-D and 1951-S. The other exceptions are the 1958 and 1959 type II varieties which are discussed in the next section. I’ve sub-categorized the type I varieties as type I-a (1948-1949 PDS) and type I-b (1950-1963 PDS).
What kind of roof for a type II building?
The roof covering of a type II building can be a layer of asphalt waterproofing, with a combustible felt paper covering. Another layer of asphalt may be mopped over the felt paper. TYPE III – This type of constructed building is also called a brick-and-joist structure by some.
What are the different types of construction types?
TYPES OF CONSTRUCTION TYPE I TYPE II TYPE IV TYPE V TYPES OF CONSTRUCTION TYPE I– This concrete and steel structure, called fire resistive when first built at the turn of the century, is supposed to confine a fire by its construction.
