It allows places in residential buildings where fatal fires less-commonly start to go without sprinklers, like combustible concealed spaces, small bathrooms, and small closets. NFPA 13R requires sprinklers in occupied spaces like dwelling units, hallways, and common spaces. Its instructions are primarily focused on protecting areas of residential buildings where fires typically lead to loss of life, giving occupants the time to escape. NFPA 13R modifies NFPA 13вЂ™s guidelines with a primary purpose in mind: saving lives while making the installation of sprinkler systems more affordable and accessible for residential occupancies.

Its systems aim to control fires close to where they start-wherever that may be-even if there is a lower direct risk to life safety. NFPA 13 is a stricter standard for sprinkler installations designed to protect people and property from fire. And while they are considered quite safe, they donвЂ™t provide quite the same level of protection. NFPA 13R installations can cost significantly less.

Why does the sprinkler standard thatвЂ™s used matter? NFPA 13R installations are not created with the same intent as NFPA 13 systems-and swapping one for the other is not an even exchange. To further complicate matters, different sprinkler systems can also cover different occupancies within the same building under specific circumstances. Of course, NFSA still recommends opting for the significant protection offered by automatic sprinklers. Incidentally, some occupancies above the podium top may not have to be sprinklered at all for instance, a business occupancy under certain height and area thresholds would not require sprinklers. And thatвЂ™s where the confusion kicks in.ДЇor occupancies below the podium top, the rules are crystal clear: Section 510.2 of the IBC specifically states that these areas must be sprinklered in accordance with NFPA 13 : Standard for the Installation of Sprinkler Systems.Д«ut 510.2 also states that the podium top divides the areas above and below into вЂњseparate and distinct buildings for the purpose of determining area limitations, continuity of fire walls, limitation of number of stories and type of construction.вЂќ That means sprinkler installations throughout the top portion can follow NFPA 13вЂ™s more extensive guidelines for sprinkler protection-but they may not necessarily have to.ДЇor instance, if the upper building is residential and doesnвЂ™t exceed specific height requirements, sprinklers above the podium top may be able to follow the more relaxed rules of NFPA 13R : Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies. With multiple uses comes multiple possibilities for automatic fire sprinkler installations. NFPA 13R: Why does the distinction matter?

Pedestal, or podium, construction is permitted by a special provision in the International Building Code that details requirements for a horizontal building separation allowance. To learn more about IBC guidelines for pedestal structures, refer to Section 510.2 of the model code. Typically, the entire structure is comprised of multiple stories of light wood framing over a single- or multi-story concrete or steel podium.Д¬ommon configurations include three to five stories of residential use over parking, retail, commercial and/or office space or six or even seven stories of residential use that includes the podium, with subterranean parking. The podium top that separates the lower floor(s) from the upper floors essentially serves as a horizontal firewall-and the buildings above and below are considered separate by model codes, just like buildings on each side of a standard firewall. IBC also mandates that the podium top must be supported by Type IA construction. The provision enables the three-hour fire-rated horizontal assembly that forms the podiumвЂ™s top. Podium construction is permitted by a special provision ( Section 510.2) of the 2018 International Building Code (IBC) that details requirements for a horizontal building separation allowance. Architects, city planners, and authorities having jurisdiction (AHJs) are embracing the benefits of safe structures that can incorporate multiple purposes, mixed types of construction, and less-expensive building materials. The popularity of podium construction has exploded in recent years. NFPA 13R installations in stacked mixed-use buildings.

But itвЂ™s also created ambiguity for sprinkler contractors, design professionals, and code officials, as professionals attempt to understand when to apply NFPA 13 vs. Podium construction-also known as pedestal or platform construction-has emerged as a popular approach for maximizing the use of smaller urban lots. Guidance for sprinkler contractors confused about mixed-use building sprinkler requirements
