What is a Type 2 construction?

Type 2: Non-Combustible 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.

What is Type I and Type II 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. Type 3: Ordinary: New or old buildings with non-combustible walls but a wood-framed roof.

What is the difference between type 2a and type 2b 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 is construction type D?

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. Exterior covers may be wood siding, shingles, stucco, brick or stone veneer or some other type of material.

What is Type I 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. This type of construction in which the building elements listed in IBC Table 601 are of non-combustible materials, such as concrete and steel.

What is Type 1a construction?

TYPE I-A–Fire Resistive Non-combustible (Commonly found in high-rise buildings and Group I occupancies).

What is construction Type II B?

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 are the 5 major types of construction?

The five different types of construction types

  • Type 1: Fire-resistive.
  • Type 2: Non-combustible.
  • Type 3: Ordinary type.
  • Type 4: Heavy timber type.
  • Type 5. Wood-framed type.
  • Purpose.
