    Remodel After

    We had a great experience working with Amgad and the engineering team at San Mina on our home remodel. The project was fairly complex--it included expanding our living space by building two bedrooms and a bathroom above the garage, as well as removing walls in the kitchen to create an open-concept layout downstairs that required new structural support. From start to finish, their team demonstrated a high level of professionalism and expertise. They took the time to fully understand our vision and translated it into a thoughtful, well-executed design. Their structural plans were clear and thorough, which made the construction process much smoother. Even when we encountered constraints due to city regulations, they worked closely with us to develop a revised design that both met approval requirements and aligned with our needs. We love our remodel thanks to Amgad and team!

    Outstanding experience from start to finish with San Mina Engineering. The team was professional, responsive, and delivered exactly what was promised on time. Quality of work was top-notch and the value was excellent. Highly recommend them and would absolutely work with them again.

    Construction

    Amgard and his team were excellent to work with. They helped me out with my project in Huntington Harbor. Communication was clear and effortless, they fully understood my needs and vision, and the entire process was smooth. The final outcome exceeded my expectations.

    Very professional, great service & everything was done on time. I would highly recommend this company. Our plans got smoothly through the city and contractors were able to follow them with no difficulty. We removed several retaining walls to create a more open plan.

    Thank you so much for all your knowledge and work you put into getting the approval of our wall with the city of San Juan. The wall was a long tedious job and would have been impossible without you. The other engineers we hired could not do what you did. Agmad. you are our knight in shining armor.

    Removed a wall separating the family room from the kitchen.

    Mr. Benjamin at San Mina Engineering was a great addition to the team working on my home addition and remodel. He was easy to work with, very responsive and had a fast turn around time. We built an office addition, opened up the kitchen to the family room, removed a lot of brick in the kitchen and expanded a bathroom.

    Amgad was extremely professional and was clear in how he would approach our project. When I told him about our time crunch, he was responsive and made sure to do exactly what we promised. We received 0 comments from the city and county about his work, and it expedited our project so that we are actually a month ahead of schedule. Thanks again!

    Our GC had to dig (4) 10' holes for the footings!!  Not even the San Andreas Faultline could disrupt this construction!!

My garage would flood when it rained heavily. The water was seeping/bubbling up through the concrete floor. Unfortunately,I spent a total of 20K on two other contractors before hiring Alpha. The work done by the first two contractors failed completely. When Damien from Alpha Structural initially came over, I knew I was in good hands right away. He is extremely knowledgeable, experienced, and professional. I would say the same about Brian and Nadir, who were the leads on my job. Brian especially, went above and beyond. Anytime I reached out to him he responded immediately, and was on site whenever I needed him. My garage was a nightmare scenario. I contacted just about every contractor who works on this kind of thing, from LA to San Diego. Not one of them could figure it out. Not one. This went on for 2 years. Alpha Structural took on a very tough job, and did what no other company could. They completely solved my garage flooding problem with a very strategic and comprehensive plan. Do yourself a favor and use this company! Don't waste time with others. Alpha Structural won't let you down.

We started with an ~1,600 sq ft home and Ben helped us completely reimagine it into a 3,600+ sq ft dream home that our family plans to keep for generations. What stood out throughout the process was Ben's rare combo of deep technical capability and a genuinely easy, approachable working style. Ben brought significant in-house strength to the table: full architectural design (including our California room / covered patio), plus engineering coordination around soil/civil and drainage planning. That integrated approach made the process far more seamless -- fewer handoffs, fewer gaps, and fewer "who owns this?" moments. And his pricing was fair and attractive for the level of rigor and service. As the build progressed, Ben stayed close and collaborative -- not just sending plans and disappearing. He worked with us and our contractors, answered questions, and helped keep things moving. He was also extremely responsive; he typically replied within a few hours, which makes a huge difference when you're trying to keep a project on track. Ben handled submissions and permitting with the City of Fullerton and worked through City-requested changes efficiently, saving us countless hours and headaches. He also has a sharp eye for detail -- his plans were thorough, complete, and clear -- and he brought creative solutions to get the design we wanted while respecting the budget. Our taste is traditional / Cape Cod, and he did an outstanding job translating inspiration photos into a finished design that feels classic, intentional, and timeless. We went through more than four rounds of revisions, and Ben was patient and constructive the entire time -- he worked with us until we were genuinely happy. Bottom line: Ben translated our dreams into reality, and did it with professionalism, responsiveness, and real care. We recommend him and are happy to discuss our experience with anyone considering BN Design Build. We're almost done with the build and will post pictures once finished!

    We hired OConsulting because we wanted to remodel our kitchen, laundry room and living room. Our…read moreremodel design included removing (2) walls and adding (2) windows in the kitchen, expanding the laundry room, and raising a sunken conversation pit in the living room. Upon initial contact we emailed details of our project and then had a video conference with Fredy and Nanak to discuss the project in more detail along with their services. A contract for the work was issued and signed and Fredy came out for a site visit to begin. Structural and mechanical engineered plans were then developed with a set of preliminary drawings for our review. We discussed a few adjustments we wanted to be made to the design and then finalized the design details. A stamped set of mechanical and structural engineered plans were issued and submitted to the city via OConsulting on our behalf for the city's review and approval. The engineering and plans were so well done that the only request the city had were minor verbiage to be added to the front page of the plans indicating wind speed of the area, that the property is within an HOA and that no oil drilling is located on the property. With the addition of the specified verbiage to the plans the city then approved the stamped set of plans and the building permit was successfully issued. Our experience with Fredy and Nanak at OConsulting was a pleasant experience. Both Fredy and Nanak were personally a pleasure to work with. They answered all of our questions, listened well to our design goals and vision, were attentive to our project and because of their highly skilled knowledge and skillset they made it possible for us to proceed with beginning construction on our remodel. We are very pleased and grateful for the professionalism of the service we were provided with and are very happy to recommend OConsulting. Thank you to Fredy and Nanak for the excellent service you gave to us and for making our remodel visions possible.

We laid out what we wanted and Fredy told us what we could and couldn't do. He told us he could have the plans done pretty quickly and we were happy with how it was going until.. We wanted to add a skylight and asked Fredy about it. He quickly said we couldn't and gave no real explanation why. So we did a little research, asked another engineer and found out it was possible. When we called to ask Fredy about it he YELLED AT MY WIFE and basic said not to question him. It seemed Fredy didn't want to do the extra work to look into it. He ended up adding it after I had another conversation with him. It's not over.. Once we finally get the plans and turn them into the City for review they get sent back to us. FREDY MESSED UP NORTH AND SOUTH! It then took him over 2 weeks to correct it! THIS COST US OVER 10K DOLLARS because the project was held up and we had to keep paying the mortgage FREDY MESSED UP OUR PLANS 2 MORE TIMES AND COST US OVER 20K DOLLARS IN MORTGAGE PAYMENTS AND MONTHS OF IDLE TIME Please don't be fooled by the 5 star reviews. If you are in the market for a good, timely and competent engineer I suggest you look elsewhere.
