Dallas permit notes
City of Dallas Sustainable Development & Construction reviews MEP. The MEP review tends to focus on energy compliance and TDLR/TAS interplay.
Frequently asked questions
Does Pyra Engineering design fire alarm or sprinkler systems?
No. Fire alarm system design and installation is the fire alarm vendor's scope. Sprinkler design is the fire-protection contractor / FPE scope. Pyra Engineering's scope is mechanical, electrical, and plumbing (MEP) only — we coordinate locations and conduit notes for FA/sprinkler tie-ins on our drawings, but we do not stamp those designs.
Do I need a sealed Texas engineer for a medical office project in Dallas?
For most medical offices of any meaningful size, yes. Texas Occupations Code §1001 requires MEP designs above certain thresholds to be stamped by a licensed Texas Professional Engineer. Drawings without a TX seal can stall plan review or trigger code-enforcement action. Pyra Engineering is a Texas-licensed firm; the drawings we deliver are stamped and ready for Dallas permit submittal.
What's typical turnaround on MEP drawings for a medical office in Dallas?
Standard medical office fit-outs run 2–4 weeks from kickoff to permit-ready package, depending on scope and how quickly architectural backgrounds settle. Fast-track schedules are doable when we surface the deadline at quote — we have a separate workflow for franchise-rollout pace and developer-deadline pressure.
Will Pyra Engineering stamp drawings done by a contractor or designer?
We perform an engineer-of-record review before stamping any third-party drawings. If the design is sound, we mark up the corrections needed and stamp once they're incorporated. If it isn't, we'll tell you up front rather than stamp something we don't stand behind. Stamping fees are scoped to the review effort.
Does the MBE/HUB certification benefit me on a Dallas project?
Yes if you're tracking diversity-spend goals on public-sector or large corporate projects. Pyra Engineering's HUB and MBE certifications count toward those goals; many City of Houston, county, and Fortune-500 supplier-diversity programs accept them. Bringing us in lets you both meet the goal and get the engineering.
How does Pyra Engineering quote medical offices MEP design?
Fixed fee based on conditioned area, scope (full MEP vs. discipline-specific), and project type (shell, TI, or ground-up). Quotes typically come back within one business day of receiving the architectural set or a one-paragraph scope summary. No estimates without scope — we don't do range pricing that creeps.
Do I need ASHRAE 170 compliance for a small clinic?
Yes. ASHRAE 170 applies to all spaces classified as 'patient-care areas' under the codes adopted by your AHJ. Even a 2,000 sf urgent care needs to meet it. We tag every space in your floor plan to its 170 classification on day one.
What pressure relationships are required?
ASHRAE 170 Table 7.1 specifies positive/negative/neutral for each space type — exam rooms neutral, soiled holding negative, clean storage positive, isolation rooms negative with anteroom. We build the pressure-relationship table with the room schedule.
How is outdoor air sized for medical?
Per ASHRAE 170 — most patient-care spaces require 2–4 ach of OA, often 100% OA on procedure rooms. This typically requires a dedicated outdoor air system (DOAS) since packaged RTUs can't deliver that much OA reliably.
Do I need a DOAS unit?
Almost always. ASHRAE 170 forces near-100% outdoor air on most patient-care spaces, which is impractical with a packaged RTU alone. Plan space for a dedicated outdoor air system at SD; we'll size it once the program is set.
Will you stamp the medical gas piping?
We design and stamp medical gas piping per NFPA 99 for outpatient settings (oxygen, vacuum, medical air, N₂O). For surgery centers and ASCs we partner with a separately-certified medical gas verifier on the install side.
What's the difference between a clinic and an ambulatory surgical center?
Surgery centers have stricter ventilation, emergency power, and medical gas requirements. Most outpatient clinics fall under Business occupancy; surgery centers fall under Institutional I-2.1. The MEP scope and stamping requirements differ.
Do I need emergency power?
Per NFPA 110 if you have a life-safety branch (egress lighting, fire alarm) which most medical buildings do. Critical-care branches require ATS within seconds of utility loss. We size the generator and ATS at SD.
How do you handle x-ray equipment power?
Dedicated 20A or 30A circuit per unit on isolated ground, sized per the manufacturer's spec sheet. For 3D CBCT we add lead shielding coordination notes for the architect.
What about TDLR / TAS for medical?
Medical TIs almost always trigger TDLR review. Mounting heights, lever hardware, accessible exam tables, accessible restroom counters — all on our drawings.
How long does medical permit take in Dallas?
Most medical TIs run 3–6 weeks from MEP submittal to permit. If state TDLR architectural barrier review applies, add 2–3 weeks. We identify TDLR triggers at scope review.
Do I need a separate health-department review?
TX DSHS reviews specific clinic types (dialysis, abortion clinics, end-stage renal). Most general clinics don't trigger DSHS. We confirm at scope.
What's the energy code for medical?
IECC with healthcare exceptions. Hospital-grade spaces often get OA exceptions but lighting and envelope still apply. We document with COMcheck.
How do you coordinate with the medical equipment planner?
Equipment planner provides room data sheets with electrical, water, drain, gas, vacuum, RF requirements. We integrate at SD so MEP rough-in matches equipment locations exactly.
Do you handle hand-wash sink locations and ADA?
Yes — hand-wash sinks per ASHRAE 170 (one per exam room minimum, plus per CDC/AHJ requirements). ADA-compliant fixture mounting heights and clearances are on our drawings.
Is the autoclave / sterilizer scope yours?
We stamp the rough-in (water, drain, electrical, exhaust) for owner-furnished sterilizers. Equipment selection is typically owner/equipment-planner.
What's typical cost premium for medical vs office TI?
30–50% higher MEP scope in our TX portfolio, driven by DOAS, ASHRAE 170 pressure relationships, and (often) emergency power. Medical gas adds another 5–10%.
Will you provide construction administration?
Yes — including hospital-grade pressure-relationship verification and medical gas commissioning support. Critical for getting a passing TJC / state inspection.
Do you handle pneumatic-tube and nurse-call low-voltage?
Vendor-installed; we coordinate locations, power, and conduit pathways on our drawings.
How do you design for infection control?
Pressure relationships, terminal HEPA filtration where required, anteroom design for isolation, and dedicated zoning for clean vs soiled paths. All per ASHRAE 170 and CDC guidance.
What if I need to expand later?
We size the DOAS, panels, and gas supply with future-expansion headroom when the budget allows. We'll flag the capacity assumption explicitly in the design narrative.
Open: Texas Tenant Fit-Out MEP Schedule Risk Survey (Q2 2026)
We’re surveying 100+ Texas GCs, architects, and developers on what actually breaks tenant fit-out MEP schedules — and what predicts the projects that stay on time. If you’ve shipped two or more TX commercial fit-outs in the last 12 months, your data would help.
