Which Type of Construction is Called Ordinary Construction?

The term "ordinary construction" refers to a specific type of building construction commonly used in the United States. This brief review aims to provide a clear understanding of ordinary construction, highlighting its positive aspects, benefits, and suitable conditions for its use.

I. Definition of Ordinary Construction:

Ordinary construction refers to a building construction method that uses non-combustible materials, such as concrete, masonry, or metal, to create a structure. It is a widely recognized and accepted type of construction in the United States.

Positive Aspects of Ordinary Construction:

  1. Fire Resistance:
  • The use of non-combustible materials in ordinary construction enhances fire resistance, reducing the spread of flames within the building.
  • This construction type ensures a higher level of safety for occupants and minimizes the risk of structural damage during a fire event.
  1. Durability and Longevity:
  • Ordinary construction materials, such as concrete and steel, provide exceptional durability and longevity.
  • Structures built with these materials can withstand the test of time, requiring fewer repairs and maintenance, which translates into cost savings in the long run.
  1. Structural Integrity:
  • Ordinary construction methods emphasize the use of robust materials, resulting in buildings with excellent structural integrity

Type III Construction: Ordinary

Also known as brick-and-joist structures, Type III buildings consist of either tilt-slap or reinforced masonry walls. These materials are non-combustible. That is to say, some of the interior structural elements (frames, floor, ceilings, etc.) are made with wood or combustible materials.

What are the 4 types of construction?

The four main types of construction are: residential construction, commercial construction, industrial construction, and infrastructure construction.

What is Type 1 and Type 2 construction?

Type I: Noncombustible (or limited-combustible) construction with a high level of fire resistance, typically concrete construction. Type II: Noncombustible (or limited-combustible) construction with a lower level of fire resistance than Type I, typically this is steel construction with or without fireproofing.

What is Type 3 4 5 construction?

Type 3: Ordinary: New or old buildings with non-combustible walls but a wood-framed roof. Type 4: Heavy Timber: Older buildings made from thick lumber. Type 5: Wood-framed: Modern buildings with combustible framing and roofs.

Why do they call Type 3 construction ordinary construction?

Ordinary Construction (Type III) has a combination of combustible and noncombustible features. Because of its popularity, this architectural style has been termed “Main Street USA.” The exterior walls are protected by a noncombustible material and the fire resistance of the interior depends on building's age.

Which type of structure requires the least amount of fire resistance?

Type V

Type V — Wood Construction

A Type V-B construction, the most basic, does not require a fire resistance rating for any of the building elements. The building elements are the primary structural frame, bearing walls, non-bearing walls, floor construction, and roof construction.

What is a typical Type V structure?

Within Type V are the smallest buildings, such as single-family residential homes, restaurants, or small office buildings. Even small hotels could fit under the umbrella of Type V construction. The material for this type can be anything allowed by code, but it's usually wood.

Frequently Asked Questions

What is the least fire resistant construction type?

Type 5 structures

The most fire-resistant buildings, Type 1 structures, are constructed with concrete and protected steel, which can withstand high temperatures without collapsing. By contrast, Type 5 structures, the least fire-resistant, are lightweight and made of combustible materials that collapse soon after catching fire.
