Fire Protection Design Requirements: University Health Palo Alto Hospital, San Antonio, Texas

Meta Description: Fire protection design requirements for University Health's $550M Palo Alto Hospital in San Antonio — NFPA 101, 99, 13, and 72 editions, smoke compartments, and EES.

Section 1: Project Overview

University Health broke ground in January 2024 on the Palo Alto Hospital, a $550 million acute care facility on a 68-acre campus at South Zarzamora Street and Jaguar Parkway on San Antonio's South Side, across from Texas A&M University–San Antonio. A joint venture of Turner Construction, Byrne Construction Services, and Straight Line Management is leading construction, with the building targeted to open to patients in 2027.

The hospital is roughly 500,000 square feet across five stories, with a structural design that allows two additional floors to be added later. It opens with 166 inpatient beds and is planned to expand to 286 beds as the South Side population grows. The program includes a 24/7 emergency department, labor and delivery, a neonatal intensive care unit, operating rooms, inpatient units, and radiology and laboratory services, with an attached medical office building. University Health, the public health system for Bexar County, owns the facility, which means the project answers to both local code officials and federal participation requirements from the outset.

Section 2: Fire Protection Challenges Specific to This Project

This is a Group I-2, Condition 2 occupancy: it provides care for patients incapable of self-preservation, including surgical and emergency patients who cannot evacuate without assistance. That single classification drives the entire fire protection strategy. Evacuation is not the design basis; defend-in-place is. The building must hold patients safely on their floor while staff relocate them horizontally through smoke barriers, which means smoke compartmentation, sprinkler reliability, and alarm sequencing all have to work together rather than as separate trades.

The NICU, labor and delivery, and operating rooms add layers most occupancies never see. Anesthetizing locations carry medical gas piping, waste anesthetic gas disposal, and electrical reliability requirements under NFPA 99 that interact directly with smoke control and detector placement. A NICU cannot be evacuated quickly, so the relocation strategy for that compartment deserves specific attention early.

Two structural realities complicate the design. First, the planned vertical expansion means standpipes, sprinkler risers, fire pump capacity, and alarm pathway capacity should be sized for the future floor count, not just the opening configuration. Second, the staged bed expansion from 166 to 286 requires system headroom so the later buildout does not force a redesign of the alarm or suppression infrastructure. Designers also need to confirm whether the highest occupied floor exceeds 75 feet, which would trigger high-rise provisions.

Section 3: Required Systems and Applicable Codes

The City of San Antonio enforces the 2021 International Building Code and 2021 International Fire Code (effective February 1, 2023), which reference NFPA 13-2019 and NFPA 72-2019. Because University Health participates in Medicare and Medicaid, the facility must also meet the CMS Conditions of Participation at 42 CFR §482.41, which adopt NFPA 101-2012 and NFPA 99-2012. Texas hospital licensing under 25 TAC Chapter 133 reinforces NFPA 101 compliance for new construction.

The discrepancy between the locally referenced editions and the federally adopted 2012 editions is normal for hospitals. The design must satisfy the most stringent applicable provision in each case, documented through the submittal.

Section 4: What Designers Need to Think Through

Smoke compartmentation governs the floor plate. NFPA 101-2012 limits smoke compartments in new health care occupancies to 22,500 square feet, with travel distance to a smoke barrier door capped at 200 feet. On a 100,000-square-foot floor, that is a minimum of five compartments per level, and the barrier locations have to align with the relocation plan, not just square footage. Coordinate barrier walls with structural framing and ductwork before the architectural layout freezes.

The essential electrical system under NFPA 99-2012 must be a Type 1 EES with the life safety, critical, and equipment branches separated, fed by Level 1 generators per NFPA 110. Fire alarm circuit pathway survivability under NFPA 72-2019 needs to be reconciled with the defend-in-place strategy so notification and relocation remain functional during a fire.

Finally, this project has three review tracks: the City of San Antonio for building and fire, Texas HHSC architectural review for licensing, and CMS for participation. Sequencing those submittals, and resolving where their referenced editions differ, is as much a part of the work as the system design itself.

Section 5: How ProTech CDS Approaches Projects Like This

ProTech CDS designs fire alarm, sprinkler, and suppression systems for complex health care occupancies and coordinates them in BIM against structural, mechanical, and medical gas systems. Every package is reviewed by a NICET Level IV principal and delivered with a PE stamp valid in any of the 50 states, including Texas. We deliver white-label, so the construction documents carry your firm's name.
