"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."

"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."

"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."

"If you?re here looking for an architect, look no further. Francisco is the man for the job. He helped us with a garage to ADU conversion. Francisco kept us informed and communicated with us throughout the entire project. He was very professional, helpful and patient. We had tons of questions and he had the answers. He is very efficient and great at his job. We would hire him again with no hesitation. Thank you Francisco for making for making this process a breeze!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

Structural Engineering questions, answered by experts

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.

Stone, marble, and brick are common building materials of Neoclassical architecture, though you will also find wood flooring and a range of natural stone tiles. Since several home styles fall under Neoclassical architects' umbrella, a range of building materials—including traditional wood framing—will make an appearance.
