"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."

"David and his team did a great job with the drawings for our room addition remodeling project. We added a large section to the back of the house and created a 1 bedroom and a bathroom room with a small kitchen. David came up with comprehensive blueprints for the entire remodeling project, and he also generated a great 3D renderings of the addition for us. He also got for us all the permits from the city."

"Mr. Erdelyi helped me legalize a structure in my backyard. The project is still ongoing but Mr Erdelyi was very attentive, invited me to discuss creative solutions and never let me feel that the project is too small. I can appreciate the way Mr. Erdelyi takes care of his customer. I did not introduced my self as such but I am an engineer myself."
