What type of construction has structural members made of noncombustible materials and specified fire resistance?

Type 1 construction is characterized by structural members that are made from noncombustible materials, such as reinforced concrete and steel. This type of construction is specifically designed to provide a high level of fire resistance, which is critical for protecting the integrity of the structure and the safety of the occupants.

The primary objective of Type 1 construction is to limit the spread of fire and to withstand high temperatures without significant deformation or failure. Therefore, buildings utilizing this construction type are typically required to meet rigorous fire code regulations and standards, ensuring that they can endure fire for an extended period before failing.

While other types of construction may include various materials and fire resistance ratings, none offer the same level of inherent protection against fire hazards as Type 1 construction. For instance, Type 2 construction may include noncombustible materials but often has less stringent fire resistance requirements compared to Type 1. Other options, such as wood frame construction or Type 3 construction, utilize combustible materials that inherently pose greater risks during a fire incident.
