In combination with occupancy group, what determines the allowable height of a building?
Building location and site size
Building use and tenants' preferences
Construction type and fire-suppression system
Interior decoration and furniture arrangement
The correct answer is: Construction type and fire-suppression system
The allowable height of a building is primarily determined by construction type and fire-suppression system. Different construction types, such as wood frame, steel frame, or concrete, have varying structural capabilities, fire resistance ratings, and safety profiles that influence how tall a building can be built. Additionally, fire-suppression systems, including sprinklers and alarms, play a crucial role in determining height limits because they enhance safety measures against fire hazards, thus allowing for taller structures in certain classifications. Building height regulations are closely tied to the need for safety and the prevention of fire spread, especially in densely populated areas. Therefore, the combination of construction type and the type of fire-suppression system installed is critical for compliance with safety codes. This consideration ensures that buildings not only meet aesthetic demands but also adhere to health and safety standards as defined by the relevant building codes. In contrast, while other factors like location and use might influence various aspects of building design or development process, they do not directly dictate the maximum allowable height in relation to safety and structural integrity.
