What does it mean if a building is classified as Type I construction?

• A. It is primarily constructed with wood
• B. It is made of non-combustible materials
• C. It has a single story
• D. It uses a mix of combustible and non-combustible materials

Answer: (B)

A building classified as Type I construction is characterized primarily by its use of non-combustible materials. This classification is part of the fire-resistance ratings defined in building codes, which categorize buildings based on their materials and structural integrity. Type I construction typically employs materials like concrete and steel, which do not ignite and burn like combustible materials. This type of construction is designed to withstand fire for a prolonged period and to limit the spread of fire within the building, providing a higher level of safety for occupants as well as enhanced protection for the structure itself. As a result, buildings of this classification are often used for high-rise structures, commercial buildings, and other facilities where fire safety is paramount. In contrast, other options describe characteristics that do not align with Type I construction principles, such as the use of combustible materials or limitations on building height.
