"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"

"I had a great experience working with Omid Gharavi of OGV Structural Engineering for structural engineering permit services for my home in Baltimore. He was knowledgeable, professional, and easy to work with. The drawings he prepared and stamped, along with the engineering letter, were approved by the county without issue, allowing me to move forward with my home project. I truly appreciate his expertise and would highly recommend his services."

"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."

"Terry, Noor, and the whole team were incredibly professional and helpful with my project. I needed them to draft plans for an existing structure and they produced an outstanding bundle for me to submit to the county. The process was collaborative and they kept me informed on how things were going and what additional information they needed, and they also were great about including elements I wanted to see reflected in the plans. I highly recommend them and will likely hire them again if and when I decide to put an addition on my home."

"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 questions, answered by experts

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.

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar.
