"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."

"I called on a Friday evening and Jonathon answered. I needed a structural engineer inspection to satisfy an underwriting requirement of the lender for a house I was selling. Jonathon came out that weekend, was very pleasant and helpful and I had the letter I needed first thing Monday morning. I was quite impressed with his service and would definitely use him again."

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"

"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."

"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."
