Class D: Wood- or Steel-Framed Exterior Walls Class D buildings are characterized by combustible construction. The exterior walls may be made up of closely spaced wood or steel studs, as in the case of a typical frame house.
What is Type A and B 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 A includes buildings that have a higher risk such as high rise, high occupant buildings and is therefore the most fire resistant.
What is Type 3 building construction?
TYPE III – This type of constructed building is also called a brick-and-joist structure by some. It has masonry-bearing walls but the floors, structural framework, and roof are made of wood or other combustible material; for example, a concrete-block building with wood roof and floor trusses.
What do you call a metal building?
A steel building is a metal structure fabricated with steel for the internal support and for exterior cladding, as opposed to steel framed buildings which generally use other materials for floors, walls, and external envelope.What are the 4 types of construction?
The four major types of construction include residential building, institutional and commercial building, specialized industrial construction, infrastructure and heavy construction.
What is a Class B construction?
Class B buildings have reinforced concrete frames and concrete or masonry floors and roofs. The primary characteristic of a Class B building is the reinforced concrete frame in which the columns and beams can be either formed or precast concrete. They may be mechanically stressed. It is a fire- resistant structure.
What is a Class C construction?
Class C buildings are characterized by masonry or reinforced concrete (including tilt-up) construction. The walls may be load-bearing, i.e., supporting roof and upper-floor loads, or non-bearing with open concrete, steel or wood columns, bents or arches supporting the load.
What does it mean by type of construction?
What does “type of construction” mean? Within the National Construction Code (NCC) Volume One (Section C – Fire Resistance) the ‘type of construction’, generally determines how much a building is expected to be resistant to a fire (including all building elements – structural members and non-loadbearing components).What is Type 2b construction?
TYPE II-B–Unprotected Non-Combustible (Most common type of non-combustible construction used in commercial buildings). Building constructed of non-combustible materials but these materials have no fire resistance.

What is the difference between Type 3a and 3b 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.

How do you determine the construction type of a building?
Classification of a building class is based on two factors: building elements and fire-resistance rating. These factors may not be included in the submission/documentation, in which case additional information will need to be requested.
What is the difference between Type 1 and Type 2 construction?
Type 1: Fire-resistive: High-rise buildings made of concrete and protected steel. Type 2: Non-combustible: Newer buildings with tilt slab or reinforced masonry walls and a metal roof.
What is Property Type C?
A Class C property is one that is older (typically 30+ years old), in fair to poor condition, and typically not as well-located as a Class A or Class B building. They are considered to be the “riskiest” investment, but in turn, offer some of the best potential cash-on-cash returns.
What is a Type 2 construction?
Type 2 construction is typically found in new buildings and remodels of commercial structures. The walls and roofs are constructed of non-combustible materials. Specifically, walls are usually reinforced masonry or tilt slab, while roofs have metal structural members and decking.
