Oklahoma is the most predictable of Rush's licensed states, because most fire sprinkler plan review happens in one place under one set of rules. That predictability is worth using. When the submittal requirements are known and fixed, the schedule stops being a guess.
Matthew Rush holds an active Oklahoma professional engineer license with fire protection discipline, which satisfies the state's designer qualification requirement for fire sprinkler plan submittals.
Aerospace maintenance and federal aviation work anchor both major metros, with distribution along I-35 and I-40, energy-sector construction, and steady university and healthcare expansion behind them.
Every market builds something different, and the fire protection design follows the building. Here’s what we see most often across Oklahoma.
Oklahoma County
Distribution and logistics along I-35 and I-40, a large aviation and federal maintenance presence, healthcare, and continuing downtown mixed-use construction. Aviation work means NFPA 409 hangar classification and, on the federal side, UFC criteria, both of which Rush designs to. The warehouse work is conventional by comparison, but still turns on commodity classification before anything else.
Tulsa County
Home to one of the largest aircraft maintenance operations in the country, which makes hangar protection a recurring Tulsa problem, with group classification, foam-water deluge, and drainage all in play. Beyond aviation, Tulsa runs to energy-sector office, manufacturing, and industrial construction along the river and out toward the port at Catoosa.
Cleveland County
University construction and everything that orbits it: student housing, research and lab buildings, athletics facilities, and healthcare. Housing turns on the NFPA 13R versus 13 determination; research buildings bring hazardous materials and control area limits that need resolving with the architect while the design is still open.
Oklahoma & Logan County
Senior living, medical office, multifamily, and retail: the steadiest run of mid-size commercial work in the state. Senior living is the one that rewards care: occupancy classification drives whether quick-response heads, specific spacing, and residential sprinkler criteria apply, and it's a determination worth confirming before layout starts.
Tulsa metro
Manufacturing, flex, and light industrial buildings alongside a consistent volume of school and municipal construction. Flex buildings shift hazard classification with tenants, so the design's stated basis matters as much as the layout. It's what a future tenant's engineer works from.
Comanche County
Federal installation work drives the market, which means Unified Facilities Criteria alongside NFPA, federal submittal expectations, and a review chain unlike a municipal permit desk. Healthcare and institutional construction fills out the rest.
Payne County
University-driven construction: housing, research, athletics, and the private student housing that follows. The same 13R-versus-13 and control-area questions that govern Norman apply here, on a market that builds in concentrated bursts around the academic calendar, which makes turnaround the deciding factor more often than not.
Garfield & Kay County
Grain and agricultural processing, energy processing, and rural industrial work. Two things define design here: combustible dust and flammable liquids put NFPA 30 and specialized protection in play, and rural water supply routinely can't meet demand, so tanks and pumps belong in the concept and not in a change order.
The design is only half the job. Knowing who reviews it, against which adopted edition, and what the submittal has to contain is what keeps a project on schedule.
General guidance, current as of 2026. Requirements change and local amendments vary. Confirm the governing authority for your specific project.
The Office of the State Fire Marshal reviews and permits fire sprinkler plans through its online portal. Paper and email submittals aren't accepted, and submittals come in through an Oklahoma-licensed fire sprinkler company. Rush produces the engineered design package your contractor uploads.
Oklahoma requires fire sprinkler designs to be prepared by a minimum of NICET Level III certification or a professional engineer with fire protection discipline. A PE seal clears that requirement outright. No certification gap to explain, no question about whether the reviewer will accept the preparer.
CAD drawings at 1/8" minimum scale, full hydraulic calculations and specifications, a site plan showing building location, water lines, hydrants, and the fire department connection, and room names identified on every sheet. Review fees run per square foot of work area with a stated minimum. Packages that arrive incomplete don't get reviewed slowly. They get returned, and you start the clock over.
The Oklahoma Uniform Building Code Commission adopts the building and fire codes that state-reviewed projects are designed to. Some municipalities run their own review on top of that, so a project can carry both a state permit and a city one.
The full scope of Rush services is available on Oklahoma projects:
Send drawings, a scope, or a deadline, and reach the engineer directly. You'll get a straight answer on timeline and fit.
Reachable outside standard hours. Call or email the engineer directly.
