"Kamran dd a fantastic job. He reached out to me quickly and had his associate come by to look at the walls I was removing. I received an estimate for the work. Kamran worked extra long on the project to help me utilize the beams that I had pre purchased. I would recommend anyone who need a professional engineer recommendation to use OHI engineering"

"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."

"Bashir and Noorullah were a pleasure to work with. They were very detailed, providing a full set of plans to have a load-bearing wall removed in my home. Bashir was attentive and he and Noorullah answered all my questions. I would have no problem providing a strong recommendation for Structurist for any structural engineering needs especially when it comes to your home."

"We tasked Gary with a very quick turn around on a project involving a total renovation of an existing structure as well as an addition. We had a very tight time constraint and Gary was able to accommodate us, utilizing his expertise to help us make thoughtful changes to our original design and educating us on Maryland code where needed! His final product is beautiful and it was exciting to see the “after” Reno elevations! I would use him again without a second thought and recommend him to my friends. Kelly Z."

"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."

Structural Engineering FAQs, answered by experts

When comparing quotes in MD, be wary of unusually low bids, which may signal subpar materials or skipped steps. Look for detailed breakdowns specifying code compliance, soil testing, and permit requirements. Vague language or missing information about inspections is a concern. Reliable professionals provide clear timelines, references, and transparent communication, helping you avoid costly surprises and ensuring your project meets all safety and quality standards.

Helpful?

Completing structural engineering projects in Rockville enhances home comfort by improving insulation, moisture control, and airflow. Upgrades like basement finishing or open floor plans increase usable space and modernize living areas. Addressing foundation or structural issues early prevents future damage, boosts safety, and adds long-term value. These improvements create a healthier, more enjoyable environment for your family and help protect your investment.

Helpful?

In Rockville, the longevity of structural engineering work depends on careful soil analysis, especially with the area’s expansive clay and high water tables. Using moisture-resistant materials and proper drainage design helps prevent foundation issues. Attention to freeze-thaw cycles and humidity is crucial for material selection. Ensuring all work meets local building codes and addressing unique neighborhood guidelines further protects your investment and supports long-term structural stability.

Helpful?

To keep projects in Rockville safer for families, secure all work areas with barriers and clear signage. Request dust control measures to maintain indoor air quality, and ask about non-slip surfaces and rounded corners in new construction. Ensure railings and guards meet safety codes. For older homes, have professionals check for lead paint or asbestos, and consider radon mitigation for added peace of mind during and after the project.

Helpful?

For a smooth project in Rockville, begin with a thorough soil test and determine if your property is in a historic or HOA-regulated area. Locate underground utilities before excavation, and discuss your plans with neighbors if required. Meet with local code officials early to clarify permit needs. Schedule work around seasonal weather, verify your contractor’s credentials, and plan for parking or delivery logistics to avoid delays.
