"I am a homeowner who did my own home remodeling architectural design. Even though I had architect degree, but I had never done any project in Los Angeles. As everybody knows, Building and Safety has tons of regulations to follow, which made the permitting process especially difficult. I was so lucky to work with David, my structural engineer, who is very sharp, knowledgeable and hardworking. Not only did he deliver his structural design on time but also he guided me through with all details of my architectural plan. He is very responsive and generous about sharing his knowledge. It was such a surprise when David got me the permit over the counter from the city office with only one attempt, which expedited my remodeling project timeline for at least two months. Definitely recommended!!"

"-It was about 2 weeks ago that I met Mr Sal and he cam to see the project site as well to take the measurements required next day later he immediately scheduled an appointment with my local city of Westminster to find out what was exactly requested soon after he left it took only 3 days for him to develop all the structural calculations for the mother-in low quarter and the 2 car garage I was extremely pleased for his professionalism and fast expedited work. The quotes that I was provided from him were by far quite fair than the other I had interviewed prior of meeting him. Mr Sal truthfully went the extra mile to make it happen for what I was looking for. I therefore would Highly recommend to anyone in need of such works to look for Mr. Sal from AAA Engineering Design, you will never be disappointed. I want everyone to know that he is truly a great asset to our community. Thank you John Trimarco"

"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 questions, answered by experts

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Structural engineers specialize in all aspects of a building’s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding who to hire for foundation repair.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

By careful planning and reinforcement to maintain structural integrity.

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.
