What type of construction is characterized by being fire resistive?

Type 1 construction is characterized by its fire-resistive properties, making it suitable for buildings that require a higher level of protection against fire. This construction type uses materials like concrete and steel, which can withstand fire for extended periods, thus minimizing the risk of fire spread and structural failure.

In type 1 construction, the structural elements, including walls, floors, and roofs, must have a certain fire-resistance rating, often specified in hours. This rating is essential for high-rise buildings or facilities that house sensitive materials, as it provides time for occupants to evacuate and for firefighters to combat the fire effectively.

Other types of construction have varying degrees of fire resistance. For instance, type 2 construction, while also non-combustible, may have less stringent fire resistance requirements compared to type 1. Types 3 and 4 construction integrate combustible materials in their designs, which can increase the overall fire risk, thus differentiating them from the fire-resistive characteristics of type 1 construction.
