Linda was thoughtful and thorough. She careful looked over everything and even brought a large, bright light since it was after dark. She took her time, answered all of our questions, and gave us advice on other concerns and things to watch out for as well as reassuring us about things we didn't need to worry about in this situation.

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

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

By careful planning and reinforcement to maintain structural integrity.
