"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"-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 have known Steven for almost twenty-five years, we have worked together on various projects in the Film/Television industry. Steven is a good designer who is versed in many styles and has a full knowledge of period details. He has a sound understanding of architecture and knows how to create useful and attractive spaces; heâ s also a genius when it comes to problem-solving. Heâ s up to date on all available materials and how best to use them. Steven has a strong work ethic and is very conscientious, and his sense of humor and light disposition puts anyone at ease; he gets along well with people. Recently, I had Steven draw up a ramp and a flight of stairs for the front entrance to our condo building, and as expected, he did a splendid job. We worked on the design together, and he prepared the working drawings and documentation. Then, he saw it through the local authorities here in Redondo Beach. I highly recommend him to solve any design requirements you might have."

Structural Engineering questions, answered by experts

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

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 costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.

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.
