"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 placed a notice on Angi that I desperately needed an architect. I was given a list of 5 companies, however Campbell Architects (CA) contacted me first. As a matter of fact, I do not recall any of the other companies reaching out to me. When I tell you that Johnathan Campbell stepped in and did what I needed him to do which was to draw a PLAT of my property, he also went above and beyond what one would expect someone as busy as him to do. He came in and recognized that in addition to needing a PLAT, I was also having a terrible time getting the work on my property completed because a hostile neighbor continuously contacted the DOB with false statements causing me to incur numerous Stop Work Orders. When I asked Mr. Campbell what his experience was with this sort of thing, he told me and then offered his help. What I found was a very thoughtful, quiet, and professional architect who had seen it all. Not only did he understand the situation with the neighbor, he also understood my plight with the DOB and set about methodically, and very carefully stepping in to argue my case for me. He has the experience, he has the knowledge, he has the patience and he is an established and well known architect in this area, and highly respected at the DOB. It took me six months to get a response from the DOB, but once Mr. Campbell stepped in, it only took one day. My point here is that the magnitude of an individual's professionalism, knowledge and capabilities is reflected in the work product and engagement experience you the homeowner will receive. Here, Mr. Campbell made a WORLD of difference in my life as a homeowner trying to do her best against a system of mostly men who know the system, who can be cavalier and do not really care that we the homeowners have become frustrated with DOB. Mr. Campbell is an ANGEL. If you ever need an architect, he is your guy. He is a no nonsense kind of man who really, really cares about people and understands that most homeowners are "no match" for the DOB machine that controls the movement of homeowners here in the DMV. I am so grateful to Angi for creating a platform where I could find Mr. Campbell. I honestly do not know if I could have survived my nightmare ordeal without his knowledge, strength and capabilities. I now consider him to be a friend. I was shocked that he was willing to help me with the crazy man next door, but he took all of that on. He has made a difference in my mental health and ability to complete the work that I started, which the neighbor constantly stopped. I feel that I got more than an architect when I met Mr. Campbell. When people tell me they need an architect I always tell them JOHNATHAN CAMPBELL FROM CAMPBELL ARCHITECTS. This is the best company I have worked with in years. So grateful to have met him."

Structural Engineering questions, answered by experts

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

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

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

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.
