And while they are considered quite safe, they donРІР‚в„ўt provide quite the same level of protection. NFPA 13R installations can cost significantly less. Why does the sprinkler standard thatРІР‚в„ўs 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 thatРІР‚в„ўs where the confusion kicks in.Р”Р‡or 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.Р”В«ut 510.2 also states that the podium top divides the areas above and below into РІР‚Сљseparate and distinct buildings for the purpose of determining area limitations, continuity of fire walls, limitation of number of stories and type of construction.РІР‚Сњ That means sprinkler installations throughout the top portion can follow NFPA 13РІР‚в„ўs more extensive guidelines for sprinkler protection-but they may not necessarily have to.Р”Р‡or instance, if the upper building is residential and doesnРІР‚в„ўt 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.Р”В¬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 podiumРІР‚в„ўs 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.

But itРІР‚в„ўs 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.
