"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."

"OGV Structural Engineering was fast, efficient, and highly professional. They delivered exactly what was needed with clear communication and great attention to detail. I would definitely recommend them."

"Great help identifying structural issues in my old home!"

"Arrived at scheduled time; performed an in depth walk through and visual assessment; discussed issues in depth; provided verbal assessment of nature of problems and suggested repair actions.. Very satisfied with service provided and associated cost. Definitely would use APAC again."

"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."

"Very responsive and professional. Arrived on time and completed the structural examination while explaining the issues that they discovered."

"Doug was responsive and timely in providing the structural review I needed for the deck."

"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 a licensed Professional Engineer providing structural engineering services for residential and small commercial projects. I work with homeowners, contractors, and design professionals to help move projects through the permit process by providing structural calculations, drawings, evaluations, and engineering letters as needed.\n\nIn-person structural inspections are available in Maryland, DC, and Northern Virginia. Remote structural consulting is available in Delaware and North Carolina.\n\nTypical projects include load-bearing wall removal, beam and header sizing, additions, decks, foundation concerns, and framing evaluations. My goal is to provide practical, code-compliant structural solutions that are clear, efficient, and tailored to the project.

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."
