"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"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!"

"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!!"

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"We needed a master bedroom addition and a full remodel of our existing kitchen and two bathrooms. Design 1 Studio handled all of it as one project. The addition was designed to match the existing roofline and exterior perfectly. The interior layouts are functional and beautiful. Our contractor complimented the level of detail in the plans multiple times during the build. We get compliments from every visitor now."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"I had the pleasure of working with Leslie Andersen on two separate projects: an ADU and a Guest House. I can't speak highly enough about the exceptional experience we had from start to finish. First and foremost, her quick response time was truly impressive. Every query was met with prompt, detailed answers, which made the entire process smooth and stress-free. It was clear that Leslie values their clients' time and prioritizes effective communication. As for the projects themselves, the results exceeded my expectations. The ADU design is both functional and aesthetically pleasing, blending seamlessly with the existing structures while adding a fresh touch. The guest house is equally crafted with attention to detail and a clear understanding of our needs and preferences. The professionalism, creativity, and efficiency displayed throughout were remarkable. I highly recommend Leslie to anyone seeking a top-notch architecture. Her commitment to excellence and client satisfaction truly sets her apart. Thank you for making our vision a reality!"

Structural Engineering questions, answered by experts

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

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.

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.

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.

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.
