"Mr. Ohi came to our home to inspect the foundation and support walls prior to us doing home renovation work. He did a thorough visual inspection and level measurements and located some small issues, but, thankfully, recommended that no foundation work be done. Mr. Ohi was pleasant to be with and knowledgeable about residential support structures."

"Having major remodel on lower level. Contractor tried to rope me into major work (and project delay) suggesting normal cracks on cinder block walls indicated a foundation issue. When I pushed back, he put project on hold stating I needed a structural engineer to certify. I called the first two people on home advisor locally and Omid got back to me in 2-3 min, was at my house within an hour and delivered a certified report within 3-4 hours. He listened to the situation and spoke with my contractor to hear his assessment before beginning his assessment measures. He directly pushed back on what contractor stated and provided simple solution for one crack that was more than hairline. Report was meticulous, he spoke with contractor directly, and saved this project. It was more affordable than what was suggested on average costs. While I couldn’t divorce from the unethical contractor mid project—I would have been stuck with no out without the work of Omid!"

"I had a great experience working with A & A Structures LLC for the structural engineering work on my home renovation in Bethesda. They were easy to work with, extremely fast, and delivered permit-ready documents that were clearly tailored for Montgomery County DPS—right down to the correct file naming conventions, which matters more than people realize. When the county requested minor revisions, A&A responded immediately, made the updates without hesitation, and even worked directly with my developer to clarify requirements. All of this was handled under the original fee, which I felt was an excellent value. Professional, responsive, and clearly experienced with Montgomery County’s approval process—I would absolutely recommend them and would use them again without hesitation."

"We have been working with Todd Willoughby since early in 2018. We had purchased a piece of land along the Chesapeake Bay and wanted to build a small but thoughtfully designed contemporary garden cottage for our retirement. After speaking with a number of architects we chose Todd and we have been very happy with that decision. Over several months, we worked have closely with him through the several design phases, culminating in a very complete set of construction documents, that we are now using for bidding. Throughout the process, we have found Todd to be personable, smart, perceptive and creative. He has been able to translate our ideas into working drawings that one of the contractors noted was called the most detailed he has ever seen. Todd has captured our vision for an environmentally friendly house with solar and rainwater harvesting. We have met with him many times talk through the many details, choices, and constraints you inevitably face. He has done all the coordination needed with the other specialties the engineers, surveyor, and solar energy firm. Having enjoyed this first part of the collaboration, we are hiring Todd to help us through the bid evaluations and construction admin phases. The best recommendation would be our actual house, but until we get there we can say Todd has done an excellent and professional job getting us this far, and we look forward to working with him through to a completed project."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Through detailed analysis of load paths, materials, and existing damages.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
