"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!"

"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."

"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."

Structural Engineering questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

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.

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.
