Structural Assessments
Foundation leveling surveys, framing inspections, roof assessments, and post-construction certifications for insurance and permitting purposes.
Geotechnical & Environmental
Subsurface soil explorations, geotechnical reports, OSSF/septic evaluations, Phase I & II environmental assessments, and hydrology testing.
Civil Site Design
Complete civil construction plans including drainage, grading, utility, pavement, and SWPPP plans for commercial and residential site development.
Materials Testing Services
Soils, concrete, masonry, aggregates, and asphalt compaction testing. Concrete compressive strength, rebar inspection, and windstorm materials testing.
Serving the Entire Texas
Gulf Coast Windstorm Zone
ATLAS is TDI-certified to prepare and stamp windstorm plans for all coastal counties — from the Rio Grande Valley to the upper Texas coast. Fast turnaround for new construction, additions, and reroofs.
Your Project Deserves a Real Engineer.
Not a Call Center.
We're a small firm by design. That means the engineer you meet at kickoff is the same one who stamps your plans — and the same one who picks up the phone.
Direct Access to Your P.E.
Lucas Castillo, P.E., MSCE is personally involved in every project. You speak with the engineer, not a coordinator.
Fast Quotes — 24 to 48 Hours
Submit your plans and receive a competitive, detailed quote within two business days. No waiting weeks for a number.
No Project Too Small
We work with homeowners, small contractors, and developers who need a P.E. but can't get attention from larger firms. You matter here.
Deep RGV & Coastal Roots
We know the Valley's soil conditions, the coastal wind loads, and the local permitting offices. That knowledge saves you time and money.

What Our Clients Say
We've worked with homeowners, contractors, and developers across South Texas. Here's what they experience.
"Lucas turned our foundation quote around in less than a day and was reachable throughout the entire project. That kind of responsiveness is rare — we've used ATLAS on three projects now."
"We needed windstorm plans on a tight schedule for a coastal project. ATLAS had the certified drawings back to us before the city deadline. Professional, accurate, and great to work with."
"As a first-time homeowner building a custom home, I had no idea where to start with engineering. ATLAS explained everything, made the process easy, and the permit sailed through. Highly recommend."
The Engineers Behind the Stamp
When you work with ATLAS, you work with the people who sign the plans. No intermediaries.
