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 office-warehouse project in McKinney?
For most office-warehouse buildings 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 McKinney permit submittal.
What's typical turnaround on MEP drawings for a office-warehouse in McKinney?
Standard office-warehouse 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 McKinney 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 office-warehouse buildings 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.
What's the trap with sizing office-warehouse MEP?
Sizing for today and not for the next tenant. Office-warehouse buildings turn over often. We build in panel headroom and HVAC zoning flexibility at the shell stage.
Do you handle dock and roll-up door coordination?
Yes — door operator power, dock light circuits, heating at the dock face. Coordination with the dock equipment vendor is part of base scope.
How do you handle the office area's HVAC being separate from warehouse?
Two distinct systems: a packaged RTU or split system serving the office (with thermostat and zoning), and lower-grade ventilation-only for the warehouse.
Plumbing rough-in for warehouse utility sinks?
Yes — utility sink locations, hose bibs, floor drain layout for warehouse maintenance. Often missed on shell drawings.
Service entrance for office-warehouse?
Sized for combined load with future-tenant headroom. Often 400–800A 208V/3-phase for a 10,000–25,000 sf flex building.
Office vs warehouse fixture count?
Combined IPC count: office gets full restroom suite, warehouse can share or have its own. Per occupancy load.
Lighting for both zones?
Office: standard troffer LED with occupancy sensors. Warehouse: high-bay LED with photometric calc.
Energy code for office-warehouse?
IECC 2021. Different LPD for office (0.85 W/sf) vs warehouse (0.4 W/sf). We tag spaces appropriately.
Garage / parking lot lighting?
Pole base location + LED area lighting per IES recommendations + IECC light trespass requirements.
Permit cycle for flex space?
1–2 cycles. Common comments target accessible restroom layout and service-entrance coordination.
HVAC for cold storage in flex?
Refrigeration system vendor-supplied; we coordinate condensate drain heat trace, electrical disconnect, and panel space.
Do you handle compressed air for industrial flex?
Yes — distribution piping, drops, dryer. Compressor is owner-furnished.
Sprinkler and fire alarm?
Both are out of our scope. Sprinkler is the FPE scope; fire alarm is the FA vendor's scope. We coordinate locations only.
CA scope for flex?
Standard — site visits, RFI response, startup verification.
How is fee scaled for flex buildings?
Lower per sf than office TI because warehouse area is leaner per sf. Office area drives most of the design hours.
Future tenant flexibility — your design philosophy?
Headroom on panels (capacity for ×1.5 future load), HVAC zoned for sub-division, plumbing rough-in for future restroom.
Do you handle yard / site MEP?
Site lighting, hose bibs, area drainage. Civil engineer typically does main yard/site work.
What about charging stations for fleet vehicles?
We design service capacity and panel space for future charging. Charger install is typically vendor.
Leasability — does MEP matter?
Yes — flexible MEP is one of the top three things developers list when leasing flex space. We design with leasability in mind.
Do you stamp out of state?
TX and FL. Other states through partner engineers.
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.
