"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 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

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

Yes. Foundation walls are always load-bearing.
