Get matched with top structural engineers in Orange County, CA

"Excellent experience again with Alpha Structural. Charlie Rosenkranz came to see the 3-story apartment building in West Hollywood. We discussed what the soft story retrofit plans will likely include. He's knowledgeable and experienced. We appreciated his professional no-pressure approach and answering our questions. Alpha performed an exploratory investigation of the support structure, as architectural plans were not available. They engineered the plans with city approval. They then consulted with us and provided the approved THP (Tenant Habitability Plan) paperwork. Production Manager Dave Schlaich and Job Supervisor Seth Price met me before construction. Dave went over the approved plans and explained the work that would be performed, and the purpose. They both answered all my questions. Lawrence and Antonio were the main work team. They were very pleasant and answered all our questions. Both had great explanations with Lawrence being very detailed. Seth provided timely progress reports by phone and text. He answered all questions, and provided contacts for automatic shut-off gas valves and stucco work. Despite Covid-19, they scheduled and passed inspections, and completed the work in under a month. We've seen projects by other companies stuck in limbo for months with no progress, so we chose Alpha to avoid complications. They removed all debris, and left the property clean. The tenants and neighbors had no complaints. Daniel Aparicio also explained various issues. Communication with everyone, including the office staff, was excellent. We're very pleased with this experience."

"Zach was very knowledgeable, friendly, and finely a Structural Engineer who pointed out the obvious with our structural problems."

"I hired Beginnings Engineering for a structural project on my 45-year-old home and worked with Jonathon Sipe and Nada. I spoke with several other firms in Orange County first. Most of the alternative proposals leaned toward complicated, expensive “perfect” solutions that might make sense on a new build, but didn’t feel grounded in the reality of an older home. Jonathon took a different approach: he listened to what I was trying to accomplish, worked through the constraints with me, and came back with a solution that made sense in the real world—while still being safe and code-compliant. On top of that, the experience was just… easy. Communication was straightforward, follow-through was solid, and they were genuinely friendly people to deal with. They weren’t the lowest engineering quote, but they were the lowest-cost path overall because their design avoided the unnecessary construction scope other firms recommended."

"I hired Kyle as my structural engineer for my ADU. Long story short, my original architect ghosted me, and left an incomplete plan and about two months before application expires. I had to change my design a bit and Kyle was so kind. He helped me finished my revision over a weekend even though he had a lot of work at hand after he leaned my situation. And the city revision only cost him a day. With his help I was able to pull my permit two days before the deadline! Excellent work Kyle! Much appreciated!"

"I recently engaged Nick Engineering for a kitchen remodeling, and I must say, their structural engineering work was exceptional. Their design not only gave our house a stunning makeover but also made sure it is built to last. The teams professionalism, responsiveness, and commitment to meeting our expectations made the entire project a breeze. I highly recommend Sam and his team for anyone in need of outstanding structural engineering services for their home renovation projects"

"Raj is an exceptional engineer with a world view centered on value and helping people. He help me through a tough problem with a roof structure issue quickly and efficiently."

"Working with Jonathan has been a dream. This is the first time I've ever needed and architect and engineering for a home project, and wasn't sure what to expect, but Jonathan was great. He was incredibly patient with the adjustments and revisions that came with the process and pointed out some ideas that I never would have thought of on my own. As a bonus, the plans sailed through the city plan check, getting approved the very next day with no comments. I strongly recommend DesignX."
