About
PEI Engineering PLLC helps homeowners, contractors, builders, and property owners turn project ideas into clear, coordinated plans for permitting and construction. We bring residential design, structural engineering, civil engineering, and MEP engineering together to reduce the back-and-forth of managing separate design services. Whether you’re planning a custom home, addition, remodel, ADU, garage or patio conversion, deck, or commercial tenant improvement, we tailor our work to your project rather than offering a one-size-fits-all package. We also provide foundation design, beam sizing, structural assessments, and PE-sealed engineering letters. Our goal is to provide practical design and engineering solutions with clear scope, straightforward pricing, responsive communication, and continued support throughout permit review. For permit-plan projects, we include unlimited revisions within the agreed scope until permit approval. Engineering plans and reports are prepared under the responsibility of, and sealed by, the appropriately licensed Professional Engineer. Send us your project location, a brief description, and any available plans or photos, and we’ll review your needs and provide a proposal for the next step.

We had a great experience working with Sam at PEI Engineering on our home design and engineering plans. He was responsive, explained everything clearly, and took the time to answer our questions. Having the architectural, structural, and MEP plans coordinated through one company made the process much easier. We appreciated his attention to detail and willingness to work through our changes. Highly recommend!

We sure are glad we found Sam at PEI Engineering. He helped us with our house plans, answered our questions in plain English, and was easy to get ahold of. We had a few changes along the way, and he worked through them with us. Having all the design and engineering handled in one place made things a whole lot easier. Good folks to do business with, and wed sure recommend them!

Having someone I could call when questions came up made a big difference. Sam handled the design and permit plans for my new home in Kansas City, helped me through approval, and answered my contractors questions during construction too.

Sam from PEI Engineering assisted us in creating as-built, permit-ready drawings for our pergola/patio cover in Dallas. He was incredibly responsive, efficient, professional, and easy to collaborate with. Its evident that they comprehend your requirements and possess the technical expertise to thoroughly inspect and analyze projects to the highest standards. I wholeheartedly recommend him to anyone seeking engineering or permit drawings.
