Fire Protection Design Requirements: Harris Health John M. O'Quinn Hospital, Houston, Texas

Meta Description: Fire protection requirements for a 12-story, 390-bed Level I trauma hospital under construction in northeast Houston. NFPA 101, NFPA 13, and NFPA 72 code analysis.

Section 1: Project Overview

Harris Health System broke ground in May 2024 on a 12-story, 1.3-million-square-foot replacement hospital on the campus of Lyndon B. Johnson General Hospital at 5656 Kelley Street in northeast Houston. Named the Harris Health John M. O'Quinn Hospital following a $40 million philanthropic commitment from The John M. O'Quinn Foundation, the facility is designed to be Harris County's first Level I trauma-capable hospital outside the Texas Medical Center.

The project is being delivered as a construction manager at-risk contract, with McCarthy Building Companies serving as CMaR, HKS Architects as designer of record, and Arup providing mechanical, electrical, and plumbing engineering. Funding comes from a $2.5 billion bond measure approved by Harris County voters in November 2023. At completion, the building will house 390 private patient rooms—with structural capacity to expand to 450—along with 15 standard operating rooms, one hybrid operating room, a dedicated emergency department, Level III NICU, and a rooftop helipad.

The structure topped off in January 2026. Opening is scheduled for January 2029. The project serves a region that carries the largest uninsured population in the country and has historically lacked Level I trauma coverage outside the Texas Medical Center.

Section 2: Fire Protection Challenges Specific to This Project

A 12-story acute care hospital in a Gulf Coast metro presents a specific combination of fire protection requirements that affect system design decisions from schematic design through commissioning.

Occupancy classification and smoke compartmentalization. Under NFPA 101-2021, this building is classified as a Health Care Occupancy. Chapter 18, which governs new health care occupancies, requires full automatic sprinkler protection, smoke compartmentalization with a maximum of 22,500 square feet per compartment, smoke detection in corridors, and horizontal evacuation rather than vertical evacuation of patients. With 390 beds and clinical areas distributed across 12 floors, the number of smoke compartments, barrier locations, and corridor detection layouts must be resolved during schematic design—not at permit. These decisions affect structural drawings, mechanical penetration locations, and rated wall construction detailing throughout the building.

Hurricane resilience and emergency power coordination. Houston's Gulf Coast exposure means emergency system design and sequencing receive heightened scrutiny. The O'Quinn Hospital incorporates a co-generation plant designed to operate in island mode during utility grid disruption, backed by a central utility plant built to N+1 reliability standards. For fire protection, this means the emergency power supply system (EPSS) governed by NFPA 99-2021, Chapter 6 must be coordinated against the co-generation plant's automatic transfer sequences. Generator sizing, automatic transfer switch timing, and fire pump power feeds all intersect with the hospital's resilience strategy in ways that require deliberate early coordination between the fire protection engineer, electrical engineer, and commissioning team.

High-rise provisions. At 12 stories, the building exceeds the 55-foot high-rise threshold under the 2015 International Fire Code as adopted by the City of Houston (revised April 2022). This triggers high-rise fire protection requirements—a Class I standpipe system throughout, voice evacuation capability integrated into the fire alarm system, and a fire command station—in addition to the Chapter 18 health care occupancy requirements. High-rise and health care provisions do not replace each other; both apply simultaneously.

Water supply and fire pump demand. A fully-sprinklered 1.3-million-square-foot high-rise hospital with multiple Class I standpipe risers places substantial combined demand on the available water supply. Northeast Houston's water pressure and flow must be verified through a fire flow test before system design begins. An in-building fire pump is likely required, and its power supply must be coordinated with the essential electrical system.

Section 3: Required Systems and Applicable Codes

The applicable codes for this project are governed by the City of Houston Fire Marshal's Office, the Texas State Fire Marshal's Office (SFMO), the Texas Health and Human Services Commission (HHSC), which licenses acute care hospitals, and federal Centers for Medicare & Medicaid Services (CMS) conditions of participation for facilities receiving federal reimbursement.

NFPA 101-2021 Chapter 18 governs the fundamental life safety requirements: sprinkler protection, smoke compartment size limits, corridor construction, and means of egress configuration. NFPA 99-2021 governs the emergency power system, essential electrical system branch categories, and medical gas systems in patient care spaces. For a CMS-certified acute care hospital in Texas, these two codes must be read together—not sequentially.

The Texas SFMO adopted NFPA 101-2021 and NFPA 1-2021 effective September 1, 2023. The City of Houston's fire alarm code is based on NFPA 72-2019. Designers should confirm the specific edition of NFPA 13 referenced by the Houston Permitting Center for this occupancy type at the time of permit submittal, as local adoption records show variation in the reference edition.

Section 4: What Designers Need to Think Through

A project at this scale requires fire protection design decisions to be made and locked in during schematic design. Several issues demand early resolution.

Smoke compartment boundaries versus structural grid. NFPA 101-2021 limits smoke compartments to 22,500 square feet and requires smoke barriers to be two-hour fire resistance-rated assemblies. On floor plates of this size, the structural grid and mechanical distribution paths must be checked against smoke barrier locations before structural documents are issued. Penetrations through smoke barriers require listed fire-rated assemblies; conflicts discovered at permit submittal result in costly redesign.

Fire alarm system architecture for high-rise health care. High-rise hospitals require voice evacuation systems under both the IFC high-rise provisions and NFPA 72-2019. The system must support selective notification to individual floors and compartments, simultaneous pre-recorded messaging, and interface with the hospital's nurse-call and Code Blue infrastructure. Coordination between the fire alarm designer and the building technology consultant must begin at design development—not during permit.

Emergency power sequencing under NFPA 99. NFPA 99-2021 defines Type 1, Type 2, and Type 3 essential electrical system branches, each with specific automatic transfer timing requirements. The O'Quinn Hospital's co-generation island-mode strategy requires precise sequencing of transfer switches relative to generator output and fire pump starting. The fire protection engineer, electrical engineer, and AHJ must align on this sequencing before electrical documents are finalized.

Special hazard spaces. Every hospital contains spaces that fall outside the main sprinkler design and require individual hazard analysis: soiled utility rooms, hazardous material storage, generator rooms, electrical switchgear rooms, and commercial cooking hood suppression systems. Each requires a separate code determination early in the design process to avoid mid-construction surprises.

Section 5: How ProTech CDS Approaches Projects Like This

Health care projects benefit from fire protection design that is locked in during schematic design—not negotiated through submittal review. ProTech CDS provides complete fire protection design for hospitals and acute care facilities nationwide, covering fire alarm systems per NFPA 72, sprinkler systems per NFPA 13, suppression systems for special hazard spaces, and design team coordination on NFPA 101 and NFPA 99 compliance strategy.

Every set of documents we produce receives NICET IV review before it leaves our office. We hold contract professional engineer stamps in all 50 states, which means we can stamp and seal drawings for direct submission to the Houston Fire Marshal's Office and the Texas State Fire Marshal. We provide white-label design services for general contractors, MEP engineering firms, and fire protection companies that need qualified capacity on large healthcare projects.
