A-1 Engineering, LLC was formed in 2011 with the vision of providing Texans with non-biased and objective engineering services for their everyday projects and building inquiries.

We recognized that the common property owner needed better information to help them with managing their properties. 

As we have grown, so have our services. Understanding that drainage issues were having a significant impact to the performance of our clients properties, we added a civil drainage engineer to our team. 

Together, the civil and structural engineers collaborate on providing a more comprehensive assessment on factors that can be causing issues with your foundation. 

Mission Statement:  We are professionals committed to the safety of the public. Through our commitment, we strive to educate the public and our clients to facilitate better-informed decisions relative to the design, construction and performance of their structures and projects. We hope that our efforts promote the profession of structural and civil engineering and that our clients benefit from our experience, knowledge and understanding in engineering and construction.

A1E was the structural engineer of record for the New High School at the Atonement Academy.

Our Specialty

Whether you are a common home owner, commercial developer or contractor, our team is prepared to help you develop your project. 


  • Before you get foundation repair, consult with our engineers to see if your building will really benefit from foundation repair. You might end up spending thousands on work that has no benefit to your building.
  • If you are having drainage issues around your home, consult with our drainage engineers to develop a remediation plan to help control the water.
  • Before you remove or demolish walls for renovation, consult with our structural engineers to help provide beam sizes to supplement the removal of load bearing walls.
  • So you built something without a permit, our engineers have technology that can see through concrete and analyze framing and foundations to help clear your permit inspections.
  • We specialize in assessing pier and beam foundations. We actually send a licensed structural engineer underneath your house to assess the foundation.
  • Having solar panels installed or maybe new clay tiles, our structural engineers can assess the capacity of the roof to carry the new load. The city officials may want a letter of our assessment.
  • If you dont agree with the conclusions of your Home Warranty or home warranty engineers, our engineers are experienced in assessing foundations and buildings following the standards and criteria of the warranty company to help you appeal their decisions.
