Generally there are five types of building construction agreed upon between the international codes council icc and the national fire protection association nfpa 220 standard on types of construction.
V ii roof construction.
The building elements shall be constructed of materials as required for the type of construction in accordance with section 602 1 1 through 602 1 5 and shall have a fire resistance.
However the roof covering material is combustible.
A subset of nc construction is superior non combustible construction nc ii also known as iso 8.
The ibc distinguishes the types with roman numerals.
Or where the entire roof is.
Weight bearers in type ii b buildings are typically steel beams.
Type v wood frame.
Type ii iia and iib with noncombustible steel or concrete structural framework walls and floors type ii is similar to type i but requires lower fire resistance ratings.
Type ii noncombustible.
Type ii this type of building has steel or concrete walls floors and structural framework similar to type i construction.
Type i fire resistive.
The roof covering of a type ii building can be a layer of asphalt waterproofing with a combustible felt paper covering.
Type iii ordinary type iv heavy timber.
Type i type ii type iii type iv type v.
Type iv would be the timber framed house that took longer to blow down but still allowed the wolf.
This shall apply to non combustible constructed buildings where the following additional conditions exist.
Pitched roof construction.
Shall be classified as type i ii iii iv or v construction.
The story of the three little pigs illustrates the types of construction.
Type v would be the straw house that fell in the beginning when the wolf huffed and puffed.
Class ii asbestos work means activities involving the removal of acm which is not thermal system insulation or surfacing material.
A cut roof this is the traditional method of cutting the timber on site and building up the roof using rafters ridge boards joists and purlins etc the exact details being determined by the size of roof size of timbers etc.
The 5 types of construction classifications are.
It s a very commonly used construction type and type iib has no fire resistance requirements for any of the building elements provided that there is adequate fire.
In one of the five construction types defined in sections 602 2 through 602 5.
Type i construction requires the highest fire resistance rating whereas type v construction requires the least amount of fire resistance rating.
The walls and roof are constructed from non combustible materials such as masonry tilt slab or metal.
Where the entire roof is constructed of 2 inches of masonry on steel supports.
This includes but is not limited to the removal of asbestos containing wallboard floor tile and sheeting roofing and siding shingles and construction mastics.
