"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"

"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."

"Todd has been a pleasure to work with. We asked him for help in designing plans for a renovation for our 1960s home. The existing home had a one-car garage, and we wanted to expand that to a two-car garage and add an extra room for a second work-from home office, as both my husband and myself work remotely. After reviewing our lotâ s survey, it was discovered that we were too close to the property line to expand the current garage, which necessitated putting the new garage on the other side of the house. This added another layer of complexity to the project, as we now needed to incorporate the existing single-car garage space into our home as usable living area. Todd listened to our ideas for repurposing the space, and provided good recommendations of his own. As others have mentioned, he worked well with our builder and quickly answered questions from the county permit office, expediting the permit approval process. We would have no hesitation in using Todd for our next 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."

"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

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

Yes, they offer plans for repairs or reinforcements to address issues.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

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.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.
