Let's understand 5 types of construction.

Building  and structures are ordinarily characterized by their kind of construction dependent on one of five essential sorts:

•  Fire resistive  - In this kind of construction the basic components comprise of non-ignitable materials, generally, steel or concrete, that manage the cost of an imperviousness to fire rating that gives a given fire assurance execution continuance against the impacts of fire.

• Non-combustible - Similar prerequisites that apply to Type I construction additionally apply to this kind of construction, with certain distinctions. This kind of construction may not bear the cost of any imperviousness to fire rating for the uncovered basic components.

• Ordinary - In this construction type, all or some portion of the inside auxiliary components might be ignitable. Outside dividers are required to be developed with non-burnable materials. They can have an imperviousness to fire rating, contingent upon the level partition and whether they are bearing or non-bearing dividers.

• Heavy timber - Substantial timber basic individuals – segments, pillars, curves, floors, and rooftops – are unprotected wood with enormous cross-sectional zones.

• Wood frame/combustible - This sort of construction utilizes auxiliary individuals altogether of burnable materials, typically wood, and is separated into two subgroups: ensured (basic components secured as required) or unprotected (no imperviousness to fire prerequisite).
