Exploring Construction Types: Key Features and Benefits

In describing construction types, it is essential to consider two crucial features that determine the characteristics and safety of a structure. This article aims to provide a clear understanding of these features and their benefits. Whether you are a construction professional, homeowner, or simply curious about building types, this information will help you make informed decisions.

I. Key Features Considered in Describing Construction Types:

  1. Material:
  • Buildings can be categorized based on the material used in their construction. The two primary material types are:

    a. Combustible: These structures primarily use wood and other flammable materials. They are susceptible to fire hazards and require additional fire safety measures.

    b. Non-combustible: These buildings utilize materials like concrete, steel, and masonry, which are less prone to fire. They offer enhanced structural integrity and increased fire resistance.

  1. Fire Resistance:
  • Construction types are further classified based on their ability to withstand fire. The two main categories are:

    a. Type I: These buildings offer the highest level of fire resistance. Constructed using non-combustible materials, they can withstand intense fires for an extended period, providing significant protection.

    b. Type II: These

Check out the list below for more information.
  • Type I Construction: Fire Resistive.
  • Type II Construction: Non-Combustible.
  • Type III Construction: Ordinary.
  • Type IV Construction: Heavy Timber.
  • Type V Construction: Wood-Frame.
  • What tactics should ladder crews apply to the different types of construction?

How do you determine construction type?

The construction type will detail two main attributes of the building elements: whether or not the materials are combustible or noncombustible (ex: wood versus steel frame), and the degree to which these building elements are required to be rated for fire-resistance (ex: fireproofed steel versus exposed steel).

What are the 4 types of construction?

4 types of construction projects
  • Residential. Residential construction projects primarily help to address the housing needs of society.
  • Commercial. Commercial construction addresses the needs of commerce and trade.
  • Infrastructural.
  • Industrial.
  • Private residential.
  • Private commercial.
  • Public projects.

What are the 4 types of building structures?

Main types of building structures
  • Wood frame. Wood is one of the oldest and most popular construction materials in the world.
  • Light gauge steel.
  • Load-bearing or joisted masonry.
  • Steel frame.
  • Concrete frame.
  • Pre-engineered construction.

What is Type 3 construction?

TYPE III-A--Protected Combustible (Also known as "ordinary" construction with brick or block walls and a. wooden roof or floor assembly which is 1 hour fire protected).

What are the two types of construction?

The first type of construction is ground-up or new construction. But isn't all construction new. Yes but in this definition, the second type of construction is renovation work on existing buildings. So there is ground-up new construction and renovation construction of existing buildings.

What two elements define a building's construction type?

The construction type will detail two main attributes of the building elements: whether or not the materials are combustible or noncombustible (ex: wood versus steel frame), and the degree to which these building elements are required to be rated for fire-resistance (ex: fireproofed steel versus exposed steel).

Frequently Asked Questions

What are types 1 and 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 type of construction is the commercial structure?

TYPE II-B--Unprotected Non-Combustible (Most common type of non-combustible construction used in commercial buildings).

What is Type A or B construction?

All construction types except for Type 4 fall into one of two subcategories: Type A or Type B. Type A buildings are “protected” constructions and Type B structures are “unprotected” constructions. Protected constructions are more fire-resistant than unprotected constructions.


What type of construction would a single-family residence most likely be?
Type V: Wood-Framed

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.

What is an example of a Type 3 building construction?

Type 3: Ordinary Schools, businesses and houses with non-combustible walls and wood roofs distinguish themselves as Type 3 buildings. While older buildings tend to have conventionally framed roofs, newer buildings offer lightweight roof systems.

What type of construction are most residential houses?
Wood-Framed Type V

They are the only construction type that allows combustible exterior walls. Type V also allows a combustible interior (structural frames, walls, floors, and roofs) made entirely or partly out of wood. This type is commonly found in modern homes.

In describing construction types, what two features are considered?

What is construction type IV?

Type IV buildings have noncombustible exterior walls and interior elements. Though these buildings contain combustible materials, they generally fare well when exposed to fire. Their structural mass also makes them more resilient against collapse.

What is a Type IV building also described as ______________ construction?

Type IV: Heavy Timber

Also referred to as mill construction, heavy timber buildings are made with large pieces of wood that have been treated to resist fire. These buildings must also have a sprinkler system installed.

What is Type IV construction quizlet?

TYPE IV--Heavy Timber (also known as "mill" construction; to qualify all wooden members must have a minimum nominal dimension of 8 inches.) -Light Non Combustible buildings are buildings with exterior walls of light metal or other Noncombustible material and with Noncombustible floors and roofs.

  • What is the difference between Type V and Type IV construction?
    • As the fire resistance of the building materials increases, you have the ability to construct larger facilities. A hotel made of Type V construction might only be 7,000 square feet, for example, whereas a Type IV heavy timber hotel could be 20,000 square feet.

  • A structure under construction is considered what
    • Sep 16, 2004 — A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in
