"Jeremy was great to work with and very detailed and professional with his review of my homeâ s structure as well as the report he provided. Based on his findings I did have work done on my 62 year old home foundation to hopefully insure I get another 62. Thank you Jeremy!"

"CASNA Design provided us the blueprint not just for our house but our home--and how we enjoy our lives in it. My husband and I were elated with the architectural design plan and are thrilled with the outcome! Mr. Castillo Navia listened to us and brought our vision to life, presenting us an interior design book to solidify our wishes, and inspiring us further with his own artistic ideas. He provided us fully-completed architectural and sealed structural engineering sets of drawings. One aspect meaningful to us was his focus on customer care, which afforded such a wonderful experience. He is a consummate professional: not only highly skilled and cutting-edge, but also passionate about his work and his field. He was responsive and punctual, with transparent and competitive pricing. From start to finish, he made the process as smooth as possible, including helping us question potential contractors and compare bids, and handling the complicated permitting process. We are so happy we used CASNA Design and highly recommend the firm!"

"Tim was very professional, he was prompt in responding to messages. He showed up on the time for structural inspection and did thorough inspection. I highly recommend him considering my earlier experiences with other structural engineers, how they carry out their inspections and never give any definitive answers."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering FAQs, answered by experts

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

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. 

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.
