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 Arkansas engineer for a residential project project in Little Rock?
For most residential projects of any meaningful size, yes. Arkansas Occupations Code §1001 requires MEP designs above certain thresholds to be stamped by a licensed Arkansas Professional Engineer. Drawings without a AR seal can stall plan review or trigger code-enforcement action. Pyra Engineering is a Arkansas-licensed firm; the drawings we deliver are stamped and ready for Little Rock permit submittal.
What's typical turnaround on MEP drawings for a residential project in Little Rock?
Standard residential project 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/Arkansas MBE-certified certification benefit me on a Little Rock project?
Yes if you're tracking diversity-spend goals on public-sector or large corporate projects. Pyra Engineering's Arkansas MBE-certified and MBE certifications count toward those goals; many City of Little Rock, 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 residential projects 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 you do Manual J/S/D on every residential project?
Yes — the adopted Arkansas code editions residential and most Little Rock amendments require it. Most rejections trace to a missing Manual S equipment selection or a Manual D duct calc.
What's the typical multifamily MEP scope vs single-family?
Multifamily adds: common-area MEP package (corridor, mailroom, amenity), domestic water booster sizing for upper floors, and centralized service/metering strategy.
How do you handle pool / outdoor-amenity MEP?
Pool electrical (bonding, GFCI), pool plumbing, pool HVAC (for indoor pools). All stamped under the same package.
Generator and EV charging — base scope?
Yes — included in base scope when shown on architectural plans. Adding them post-permit is a re-submit.
Code edition for AR residential?
Most AR cities: 2021 IRC for single-family, 2021 IBC for multifamily. the adopted Arkansas code editions residential edition varies.
How are restrooms counted for multifamily common areas?
Per IPC for the public spaces (leasing office, amenity). Unit restrooms follow IRC.
Energy code documentation?
REScheck for individual residences, COMcheck for multifamily common areas.
Trash chute and recycling room MEP?
Multifamily standard scope: power, lighting, ventilation. Sprinkler is the FPE scope; we coordinate locations only.
Garage ventilation for multifamily?
Per the adopted Arkansas code editions 404 with CO/NO₂ sensor controls for variable demand. Garage ventilation is a top operating-cost line item.
Permit cycle for multifamily?
2–3 cycles typically. Common comments target accessible unit count (Fair Housing) and life safety.
Do you handle smoke detection / fire alarm?
No — fire alarm and smoke detection are NOT in our scope for either multifamily or single-family. Both are the fire alarm vendor's scope.
Manual J accuracy — does it really matter?
Yes — undersized HVAC means hot rooms, oversized means short-cycling and humidity issues. Manual J done properly is the difference between comfort and call-backs.
Solar PV coordination?
We coordinate service entrance for PV interconnection per NEC 705. PV system design is typically vendor-installed.
Tankless vs tank water heater?
Sized per IPC peak demand and code-required temperature. Tankless saves space; tank is cheaper upfront.
HVAC zoning for custom homes?
Multi-zone systems (mini-split or VRF) standard for custom luxury. We design zone-by-zone load calcs.
Smart home wiring — your scope?
We coordinate low-voltage rough-in (Cat6, HDMI back-feed, security pre-wire). Programming is vendor.
What about radiant floor heating?
Common in custom luxury. We design loop layout, manifold location, and boiler coordination.
Construction administration for residential?
Yes — site visits, RFI response, equipment startup. Smaller scope than commercial.
Do you stamp single-family custom homes?
Yes when they're above the IRC threshold (most custom homes are). Below threshold, owner can build per IRC prescriptive.
Multifamily fee compared to office TI?
Lower per sf because of repetition (typical floor plate × 5+ floors). Per-unit cost is lean.
