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

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

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

Through detailed analysis of load paths, materials, and existing damages.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
