What are the 5 types of building construction?
Find out about the pros and cons of each type of building construction so that you can make informed decisions regarding your next project.
These are the five types of building construction:
- Fire-resistant
- Non-Combustible
- Ordinary
- Heavy-Timber
- Wood-framed
Fire-resistant types of construction
This type of construction is the least combustible in terms of fire resistance ratings. They are easily identifiable by their height. Built of concrete and steel, fire-resistant buildings can be more than 75 feet tall. These buildings are built to resist fire and prevent fires from spreading.
Non-Combustible types of construction
Non-combustible structures are similar to fire-resistant buildings. They have walls, partitions columns, floors, and roofs that are not combustible. They are less resistant to fire and can not withstand the spread of fire as well as Type I.
Are the Ordinary construction type building protected against fire?
These buildings are also known as brick-and-joist constructions. This construction uses brick or block walls and a wooden floor or roof that isn't protected from fire. The interior structural elements, such as floors, ceilings, and frames, can be used to support all or part of the structure.
Do Heavy-Timber construction projects hold up against fires?
Type IV buildings are noncombustible interior and exterior walls. These buildings can be made from solid or laminated timber. All wooden members must meet dimensional requirements. All wood columns, beams, girders, and beams must have a minimum of 8 inches in thickness. These types of buildings can catch fire but require large amounts of water to extinguish.
What are Wood-Framed buildings?
The most combustible of all types are wood-framed buildings. These are the only types of construction that permit combustible exterior walls. Type V allows for a combustible interior, including structural frames, walls, floors, and roofs made entirely or partially from wood. This type is common in modern homes. These homes often include exposed wood, which means they are not fire-resistant.
Different construction types and their pros and cons
Type of Construction
- Fire-resistant
- Non-Combustible
- Ordinary
- Heavy-Timber
- Wood-framed
Pros
- Fire resistant, durable
- More options for building materials
- Building stays cooler in summer, warmer in winters
- Resilient to collapse
- Abundant resources, low cost
Cons
- Most expensive
- Not as fire-resistant
- Less fire protection
- Will require large amounts of water in case of fire
- Highly combustible, creates environmental waste
How to determine the type of construction you need
Scope
Large commercial buildings are constructed in different ways than smaller ones. There are several building types that can be classified according to their purpose: residential, commercial, industrial, educational, and institutional. The building's purpose will influence the type of building material that is used.
Size
Fire-resistant properties are less likely to be found in smaller buildings. The size of a building also influences the sprinkler thresholds, fire areas, as well as the type of the building.
Load-bearing limitations
The building's capacity to support loads increases with increasing size. The construction material must be strong enough to withstand heavy loads. Wood is not suitable for supporting superstructures with multiple floors.
Speed
Lower-construction buildings are easier to erect. Because of the shorter time required for design and construction, this is why they are faster to erect. Also, the labor required is less and construction materials can be used to speed up building.
Cost
The construction type will be determined largely by the cost of the project. Because the cost of a project has a significant impact on the selection of materials, labor quality, artistry, as well as the scope of the project. Higher construction project types will require more money than lower types.
Environmental factors
It is important to consider the environmental factors when choosing which buildings we can build. To protect them from the tidal surges, buildings are raised in coastal areas. Buildings in earthquake-prone areas are also more diverse than those in other regions. Stiff structures can easily fall during earthquakes and fires.
You should now have an idea of the various construction types. Understanding the different construction types will help you better appreciate the buildings that we live in. Understanding the construction types is crucial information to ensure safety and help people anticipate dangerous situations.
