He is professional, thorough, knowledgeable, and extremely detail-oriented in everything he does. One of the things we appreciate most is that he not only provides excellent structural engineering solutions, but he also brings thoughtful ideas and practical problem-solving to projects. He works collaboratively with the entire team and always takes the time to make sure every detail is properly considered. His plans are clear, well thought out, and reliable, and we have always felt confident recommending him to our clients. We truly value the working relationship we have built with him over the years and look forward to continuing to work together on many more projects. We have worked on projects throughout Orange County. Have done work with him in Newport Beach and many other coastal communities. Highly recommend.

These 5 star reviews have to be from friends and family. 1. I couldn't get the staff to answer emails in a timely manner. 2. The engineer made changes that I never agreed to. 3. The engineer could not understand simple concepts. He would ask me a question. I would answer it then here we are 6 weeks later going over the same questions. 4. The engineer made a request. I honored the request. I reference the request in an email and he tells me he never made the request. I attach his emails with the request! He then sticks to he didn't make the request. I have at least 15 total complaints but I will stop here. This was by far the worst engineer I have ever done business with. Its hard to believe businesses like this are still operational.

He didn't just finish on time, he also did such a phenomenal job. Everything was perfect, quality and cleanliness. Extremely satisfied with every little thing that was done! Ben Hamed is such a great guy, very professional, easy to communicate with, and delivers great work. I highly recommend working with him for any project from a small to big one!

From start to finish, the level of professionalism, expertise, and attention to detail was truly outstanding. The engineer demonstrated a deep understanding of structural integrity while also respecting the design vision for the space. He carefully evaluated the existing structure and developed precise plans to safely support the load while allowing us to achieve the open, modern kitchen we wanted. His calculations and documentation were thorough and well-organized, which made the permitting and construction process much smoother. What impressed me most was his ability to balance technical precision with practical solutions. He communicated clearly, answered all questions patiently, and ensured the plans were easy for the contractor to follow. The result was a seamless transformation--our kitchen now feels bright, spacious, and beautifully integrated with the rest of the home. If you need an engineer for structural modifications, especially for projects involving load-bearing walls, I highly recommend his services. His expertise, reliability, and commitment to quality truly set him apart.

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.

We hired BN Design Build for a total remodel that had major sentimental value -- the kind of…read moreproject where you don't just want a good result... you need the right partner. 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!
