Engikeering provides excellent structural engineering solutions. Engikeering will provide a licensed structural engineer to deliver an accurate assessment of the potential concern and create structural solutions. If you are removing walls, adding openings in walls, adding living space, placing an additional story on a structure or other actions that may impact the structural components of an existing building, it is advisable to utilize a structural engineer to understand the full impact of the renovation. Engikeering will provide full structural design and detailing for new structures, to completely and economically meet all of the applicable building code requirements. Engikeering can help identify the cause, assess the severity of the situation, and provide any needed design to remediate the areas of concern: Foundation cracks, interior cracking and/or framing movement, natural disaster damage, sagging floors or bowing walls, rot and/or insect deterioration, undersized, strained or damaged elements, roof failure or building collapse.

"Beware of this company. I had Jonathan come out to provide me with a verbal report on the condition of some termite damage in my basement. With each visit, he wanted more drywall removed and exacerbated the perceived severity of the situation. I soon realized that he was more problem focused than solutions oriented. I decided that I would prefer to look elsewhere for services to mitigate my issue, and effectively terminated our contract. Jonathan, without my knowledge and with what I perceive to be malicious intent, then sent his partially complete report to the Village reporting my property. Half the report was guesswork as to the extent of the damage as they were about areas that he was not even able to visually inspect. The village, after reading the report, became spooked and are asking for more than I and my professionals agree is necessary to mitigate the safety risk. Needless to say, I will never again use his services and I strongly advise that others be wary as well."

Structural Engineering questions, answered by experts

A freestanding brick wall that's only one brick thick can usually stand six to eight feet high. If you need a higher wall, it should be at least two bricks thick for adequate stability, and it might require a footing to support the added weight. Additionally, some areas have regulations and codes dictating how high a brick wall can be, so check with local code enforcers to ensure your proposed wall complies with any regulations.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

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.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.
