Which construction method builds one floor at a time, using fire stops between floors?

The platform frame construction method is characterized by its practice of building one floor at a time, which allows for the incorporation of fire stops between each floor. This design is significant because it helps to slow the spread of fire vertically through the building. Each floor is constructed separately, making it easier to manage and control the structural integrity while minimizing the potential for fire to travel unchecked upward. Fire stops, typically in the form of solid materials placed between the floor and ceiling assemblies, work to compartmentalize the building and reduce the likelihood of fire and smoke migrating from one level to another. This method not only enhances the overall safety of the structure but also makes it more efficient for construction crews to work with, as they can complete each level independently while allowing for quicker installation of utilities and services.
