What is type 1 building construction?

Type 1 building construction, also known as "fire-resistive" construction, is characterized by the use of non-combustible materials, such as concrete and steel, which provide a high level of fire resistance. This type of construction is designed to withstand fire for extended periods, typically up to three to four hours, limiting the spread of flames and smoke. Type 1 buildings are commonly found in high-rise structures, commercial properties, and other large buildings where enhanced fire safety is critical. Due to their materials and design, these buildings generally have a longer lifespan and greater structural integrity in the event of a fire.
