What determines a building's construction type?
When it comes to designing a structure, the construction type is chosen based upon a number of things, such:
- Purpose of the structure – Let’s say that you want to build a detached garage to house extra an extra vehicle, a boat, and lawn equipment. ...
- Size of the structure – When building something larger than a garage or a house, say a grocery store or car dealer showroom, then a heavier construction type would be ...
- Load bearing constraints – As buildings grow in height the loads that the structure must bear increase. With that the construction type must be strong enough to handle these loads. ...

What is VA and VB construction?
TYPE VA (ISO 1): A wood-framed building. Protected construction having all major building elements with at least a 1-hour fire-resistance rating. Exception: non-load bearing interior walls and partitions having no rating. TYPE VB (ISO 1): A wood-framed building having no fire-resistance ratings.
What is the difference between Type A and Type B construction?
The main difference between the Type I-A and B is that the Type I-B building has exterior walls and a structural frame that only has to resist fire for two hours, rather than the three hours of the Type I-A.
What are the 5 types of construction?
Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed.
What are the 4 types of construction?
There are 4 major types of construction: residential housing, institutional and commercial, specialised industrial, as well as infrastructure and heavy construction. Each of these types come with their own processes and requirements.
What is Type V construction in California?
Type V refers to the type of construction which includes any materials (wood, concrete, steel etc.) permitted by the code. The information conveys minimum requirements and is not a substitute for complete and accurate drawings conveying the proposed construction.
What are the 3 construction types?
There are three types of construction, namely A, B and C, which are determined by the building's class and rise in storeys. Type A includes buildings that have a higher risk such as high rise, high occupant buildings and is therefore the most fire resistant.
Which type of collapse is common for a Type V construction building?
Lean Over CollapseThis is often associated with brick veneer walls. Lean Over Collapse: Common in type V structures, this collapse occurs when the building shifts at the upper floor area, which results in the structure leaning onto adjacent buildings or totally collapsing sideways.
What is Type 1 and Type 2 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.
How many types of construction are there?
Broadly, there are three sectors of construction: buildings, infrastructure and industrial: Building construction is usually further divided into residential and non-residential.
What is B construction?
Class B buildings have reinforced concrete frames and concrete or masonry floors and roofs. The primary characteristic of a Class B building is the reinforced concrete frame in which the columns and beams can be either formed or precast concrete. They may be mechanically stressed.
What is Type 2 B construction?
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 construction project types?
Types Of Construction ProjectsResidential Building Project. ... Private Project. ... Commercial Project. ... Industrial Project. ... State Construction Project. ... Infrastructure and Heavy Construction Project. ... Federal Construction Project.
What are fire resistant building standards?
The most stringent fire-resistive standards are applied to high-rise buildings, defined as those over 75 feet tall in the IBC (that would typically be a building with six or more stories). For these Type IA buildings, all the materials used in construction must be noncombustible (such as concrete or steel) and meet the very highest fire-resistance standards. The structural frame and exterior walls must have fire ratings of at least 3 hours and floors and ceilings of at least 2 hours. The next half-tier down, Type IB, includes mid-rise office buildings and some residential structures such as apartment buildings and hotels. These have slightly lower fire rating requirements: 2 hours for structural frames and exterior walls, 1 hour for ceilings and floors.
What is a type IIIB building?
Type IIIB buildings, or “unprotected combustible” buildings have noncombustible exterior walls, while the floors and roofs may be of wood that has not been rated as fire resistant. This type of construction is found in many older warehouses.
How long does a fire rating last in a type IV building?
The greater structural mass of these wood elements assures that buildings will remain standing for longer–a fire rating of one hour is required for the structural frame. The exterior walls of Type IV buildings are made of noncombustible materials.
What is the IBC?
The IBC also lays out rules for a number of specific materials and architectural features such as acoustic insulation, millwork, and internal partitions. Before breaking ground on any project, a contractor should review the sections of chapter 6 that are relevant to that specific building and its tier on the IBC system.
How are construction projects classified?
Construction projects can be classified according to a number of criteria. Buildings may be categorized, to pick a few examples, according to their owners (say, public versus private), the materials used to build them, or their uses. The last in that list are also known as occupancy classifications and they are the basis of chapter 3 of the International Building Code (IBC) which divides structures into categories including assembly (both churches and restaurants), residential, institutional, and storage. (The IBC is a code that serves as the basis for local and state codes and helps assure that there are consistent standards within the United States.)
What is VB in construction?
Type VB covers most single-family homes and garages and is known as “unprotected frame.”. With these structures both the exterior walls and the supports can be made of any materials, including combustible ones, permitted by the IBC.
What is the highest fire resistance?
The highest tier of fire resistance is reserved for large buildings with many occupants and the lowest for single-family homes. An owner is free to follow the fire resistance requirements of a higher tier, but it will raise the cost of construction. (On the other hand, if local building codes require that a building follow a higher tier ...
What is Section 603?
While the building elements in a Type I building are to be of noncombustible materials, Section 603 provides a list of where combustible materials can be used in a Type I building . There is a list of 26 items found in Section 603 which refers you to other sections of the code that allow you to use the materials listed in this section.
What is construction classification?
Construction Classification. The different construction classifications are found in Section 602 of the International Building Code. All buildings shall be classified in one of the five construction types which are defined in Sections 602.2 through 602.5. To classify for a specific construction type, the building elements must have ...
What type of lumber is required for Chapter 6?
This can be solid sawn lumber, glue laminated lumber, structural composite lumber, or cross laminated lumber with the minimum dimensions per chapter 6 as required for structures built using Type IV construction.
What is type 3 construction?
Type III construction is where the exterior walls are of noncombustible materials and the interior building elements are of any material allowed by code. This means the interior building elements can be of combustible or noncombustible material. There is an exception that allows exterior walls of type III buildings to be built with ...
Why is it important to classify a building by its type of construction?
It is essential to correctly classify a building by its type of construction to account for the response that a building will have to a fire that occurs within the building as a result of the occupancy it serves. The building code requires that every building be classified as one out of five possible types of construction.
What is Chapter 6 of the IBC?
Chapter 6 of the International Building Code (IBC) outlines the requirements to correctly classify a building by its type of construction.
What are the different types of construction?
The 5 types of construction classifications are: Type I, Type II, Type III, Type IV, & Type V. Type I Construction requires the highest fire-resistance rating whereas Type V Construction requires the least amount of fire-resistance rating.
The 5 Types of Building Construction
There are lots of different ways to classify construction projects and categorize buildings. Things are often broken up according to the owners, materials used, or types of structures. But there’s another way to divvy things up, and it revolves around the necessary level of fire resistance a building contains.
What is the International Building Code?
The International Building Code ( IBC) governs the materials, systems, and assemblies used for structural fire resistance and fire-resistance related-construction. This is the resource we use to determine fire resistance ratings.
Fire Resistance Ratings, Defined
Each type of building construction is associated with different building elements, each of which varies in terms of fire resistance. The structural members associated with Type I construction generally receive three- to four-hour fire protection.
Conclusion
Understanding the differences between the five types of building construction is a necessary step towards a successful career in the field. If you’re interested in breaking into the construction industry, think about earning your degree from the New England Institution of Technology.
