What is the primary purpose of fire-resistive construction of a building?

The primary purpose of fire-resistive construction is to retard the spread of fire and facilitate the escape of occupants. This type of construction involves the use of materials and design strategies that can withstand high temperatures and prevent the rapid spread of flames and smoke throughout a building. By slowing down fire propagation, fire-resistive construction provides critical time for occupants to evacuate safely and for firefighters to control the situation.

Additionally, this construction method often complies with building codes that aim to protect lives and property by implementing fire safety measures. The materials used in fire-resistive construction, such as concrete, steel, and gypsum, are specifically chosen for their ability to absorb heat and resist ignition. This added layer of safety is essential in ensuring that the structure remains intact for as long as possible during a fire incident, thus safeguarding those inside and reducing overall risks.
