Structural, Civil & MEP Engineering Services in Texas
Texas has no single statewide building code, which means the edition your reviewer enforces depends entirely on which city you are building in. Add expansive clay soils across the major metros and coastal windstorm certification along the Gulf, and Texas punishes drawings prepared to a generic national standard. We engineer to your specific jurisdiction, and most standard packages are sealed in 48–72 hours.

The Codes We Design To in Texas
This is the single most misunderstood thing about building in Texas. There is no comprehensive statewide building code, so the governing edition is set city by city — and getting it wrong is the fastest route to a correction letter.
Local Adoption, Not Statewide
State law makes the IRC and IBC as they existed on 1 May 2012 the default municipal codes, but municipalities may amend them or adopt later editions by ordinance. In practice the large metros are well ahead of that baseline.
Every Major Metro Amends
Houston, San Antonio, Dallas, Austin and Fort Worth each run their own amended codes with their own submittal checklists. We confirm the adopted edition and amendments for your address before design begins.
TDI Windstorm Certification
In the designated catastrophe areas along the coast, construction requires a WPI-8 Certificate of Compliance. Engineer-based certification is available through a Texas PE, and from 1 April 2026 the Texas Department of Insurance requires compliance with the 2024 IRC or IBC.
State Energy Code
The State Energy Conservation Office sets the statewide energy minimums for single-family and commercial construction. We prepare the compliance documentation your jurisdiction requires alongside the MEP set.
Expansive Clay Foundations
Across Dallas–Fort Worth, Houston and Austin, highly plastic clay governs the foundation. Post-tensioned and stiffened slabs-on-ground designed to PTI or WRI-CRSI procedures are the norm, not the exception.
Firm Registration Matters
Texas requires both an individual PE licence and a registered engineering firm to offer engineering services. We confirm the registered entity and the named engineer of record on your quote.
Design Conditions That Actually Govern in Texas
Texas is a wind-and-soil state rather than a seismic one. Two conditions dominate almost every project, and they are the two most commonly under-designed by out-of-state firms.
- Highly plastic expansive clay across DFW, Houston and Austin, driving post-tensioned or stiffened slab design
- Hurricane design wind speeds and wind-borne debris requirements in the 14 coastal counties
- TDI designated catastrophe areas requiring WPI-8 windstorm certification
- Low seismic demand statewide, with slightly elevated activity in the Permian Basin
- Minimal frost depth, so foundation depth is driven by soil movement rather than frost
- Extreme cooling loads shaping HVAC sizing and envelope design
- Site-specific soil movement (PVR) values from the geotechnical report governing slab stiffness
- Local drainage and detention criteria that vary sharply between Houston, Austin and DFW
Who Seals Your Drawings in Texas
Your drawings are sealed by an engineer holding an active Texas licence issued by the Texas Board of Professional Engineers and Land Surveyors. Texas is stricter than most states on the business side: offering engineering services requires a registered engineering firm as well as an individually licensed engineer. We confirm both the registered entity and the named engineer of record on your quote before you commit to anything.

How We Protect Texas Clients Before You Spend a Dollar
Engineering is bought on trust long before it is bought on price. These are the commitments every Residential PE engagement carries, in writing, from the first message.
Free Quote, One Fixed Fee
Consultations and quotes cost nothing. You receive one written fixed fee against a written sheet list — no hourly billing, no surprise add-ons.
A Named Engineer of Record
Every drawing is sealed by a professional engineer holding an active licence in your project’s state, and we confirm who that engineer is before you commit.
Revisions Until Approval
If the plan reviewer returns comments, we revise the sealed drawings and respond as part of the original fee — never as a change order.
Your Documents Stay Private
Drawings, surveys and site information are used only to engineer your project. They are never resold, published or used as portfolio material without consent.
48–72 Hour Turnaround
Most standard packages are sealed and returned within two to three business days, so engineering is never the reason a permit slips.

Texas Engineering Questions We Are Asked Most
Which building code applies to my Texas project?
It depends on your city. Texas has no comprehensive statewide building code — state law sets the 2012-era IRC and IBC as a default, but municipalities amend them or adopt newer editions by ordinance, and the large metros generally have. We confirm the adopted edition and local amendments for your specific address before design starts, because designing to the wrong edition is the most common cause of correction letters here.
Why do Texas foundations need special attention?
Because of the soil. Dallas–Fort Worth, Houston and Austin sit on highly plastic clay that shrinks and swells with moisture, and a conventional slab will crack. Post-tensioned or stiffened slabs-on-ground designed to PTI or WRI-CRSI procedures are standard, sized against the potential vertical rise from your geotechnical report.
Do I need TDI windstorm certification?
Only if you are building in one of the designated catastrophe areas along the Gulf coast, where a WPI-8 Certificate of Compliance is required for windstorm insurance eligibility. Engineer-based certification is available through a Texas PE. Note that from 1 April 2026 the Texas Department of Insurance requires compliance with the 2024 IRC or IBC for these applications.
Is your engineer licensed in Texas?
Yes. Drawings are sealed by an engineer holding an active licence from the Texas Board of Professional Engineers and Land Surveyors. Texas also requires a registered engineering firm to offer services, and we confirm both the registered entity and the named engineer on your quote.
Do I need a geotechnical report?
For a slab-on-ground in the clay metros it is strongly advisable and often required, because the slab design depends directly on the soil movement value. Where no report exists we will tell you whether your jurisdiction will accept a design to presumptive values, or whether you genuinely need the soils work first.
Can you do the whole permit set — structural, civil and MEP?
Yes, and in Texas it is usually the better route. Keeping the disciplines together removes the coordination gaps between the foundation, the drainage and the mechanical set that cause most Texas plan-review rejections. You are still quoted per discipline so you only pay for what your city asks for.
How fast can I get sealed Texas drawings?
Most standard residential and light commercial packages are returned within 48 to 72 hours of receiving complete information. Coastal windstorm work and projects needing detention design are quoted with a specific schedule up front.
What does it cost?
We quote a fixed fee per project rather than an hourly rate, based on scope and your jurisdiction’s submittal requirements. Quotes are free and usually returned the same business day — see our pricing page or send your plans for a firm number.
We Also Seal Drawings Across The Gulf and South Central states
Projects rarely stop at a state line. We hold coverage in all 50 states and assign every project to an engineer licensed where it is permitted — these are the neighbouring states we work in most often.
