At LEVEL Engineering, we are committed to common sense, real-world engineering solutions.

So whether your need is for permitting, forensics, foundation problems, new or repair engineering designs; or just for your peace of mind - let us help you navigate your structural engineering projects.

"AMAZING! This was my first time doing an addition to our house and I called Fredy based on a referral from my neighbor. Fredy is nice, professional, caring and true to his word. He came out to the house, even though we are only adding 36 square feet (taking garage space to enlarge the bathroom), he treated me like it was his most important project. He answered all of my questions - I had a few being new to this. He provided all of the needed plans, specs and paperwork and for the best price (I compared 2 other firms). The plans were perfect and the city approved them while I was at the counter - in and out. After getting the plans approved, Fredy was there to answer follow up questions that my contractor had too. I will be using Fredy on every project moving forward and referring him to anyone needing his services."

Our firm provides structural engineering support for all phases in the design and construction process. Our primary function is to create structural plan packages for submission to the governing authority. We are also available to conduct preliminary field visits and structural observations during construction. In whichever service you need, we pride ourselves in carrying out the job professionally, quickly, and for an affordable price.

"I searched many and started off with others and nobody came close in handling what we needed. I found Richard, he came in and took care of it all; it was completed in a timely manner with his accurate thinking. He definitely thought ahead and it saved me a lot of time, grief and money. He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

Tal Mechaly was amazing at selecting all the paint colors combinations and with his design… he was able to pull it all together as one piece of art kitchen. Tal Mechaly was very easygoing person to work with, with excellent creativity skills and his thinking outside of the box ability was beyond believes."

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.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

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 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.

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
