"I was in serious need of a top structural engineer to evaluate exterior remodeling on my home. Previously I hired someone representing themselves as a contractor to complete some comprehensive work on my home. The individual quit before the work was complete, leaving me figure out the rest. After finding out this person wasn't actually licensed in the first place, I desperately needed a structural engineer to assist me. The amount of work to review was substantial, and I had a very difficult time finding a structural engineer. After submitting a request on Angi, Neal from R4 Engineering reached out to me. From beginning to end, he was kind, professional, and thorough. He scheduled a meeting with me in a very reasonable timeframe. After coming to my home, discussing the work in depth, and taking lots of photos, a report was compiled. I needed a report that served multiple purposes. I needed data to address the fraudulent contractors work, a clear road map to provide a licensed contractor for correction of the remodeling, and plans to provide the county for permitting purposes. When I received the report from Neal, I was truly blown away at detail. Only someone who takes pride in their work could assemble a report like this. The amount of hours and effort that must have gone into this is rather remarkable. Neal and R4 will definitely be my go to for structural engineering from now on."

"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."

"Chuck is a great person to work with. He guaranteed that I would get my permit for my sun room and only had to make one adjustment for the city which he did not charge extra for. The contractor was able to follow his designs with no problems. You cannot do better for drafting than working with Chuck from Buy Design!"

Structural Engineering questions, answered by experts

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

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.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

Costs depend on material choices, labor, and the extent of structural modifications.
