After purchasing a new home…read moreand enduring my first winter, I was incredibly nervous to find significant water in my crawl space and cracks along the raised foundation. I initially signed a contract with Prostruct, but after Irvin reviewed my photos, he demonstrated a level of integrity that is rare to find. Instead of taking the job, he honestly informed me that my specific issues fell outside their scope. He took the time to explain what I was seeing, referred me to a geotechnical engineer who could actually solve the problem, and issued me a full refund. I greatly appreciated his transparency and professional guidance. I highly recommend Prostruct Engineering to anyone looking for an honest assessment--they clearly prioritize the customer's needs over their own bottom line.

Their team is very professional, responsive, and easy to work with. The plans were well-prepared and detailed, and the city approved them with minimal corrections, which really speaks about their quality and attention to detail. One of the projects was on a hillside property, where the foundation requirements were quite intense, but their team handled it seamlessly with well-thought-out and detailed designs. See pics. They always delivered on time and maintained excellent communication throughout the process, keeping me informed at every step. I highly recommend ProStruct Engineering to anyone looking for reliable and efficient structural design services! A special mention to Lokesh, who I worked with directly -- he was very responsive, understood my needs clearly, and made sure everything was addressed on time.

I want to express our gratitude for Zenith Engineers Inc. prompt, professional, and outstanding…read moreservice throughout our remodeling project. From the very beginning, we were impressed with Senthil, Ryan and other members of Zenith team's level of professionalism, prompt response, architectural knowledge and effective communication.This level of service was seamless through our entire engagement with Zenith Engineers Inc., from obtaining the building permit to successfully passing all necessary inspections by the SF Building Department. No one questions their architectural work because they are so good at what they do. We had some initial concerns after reading negative reviews, but as the project progressed, it became clear that those comments were based on personal grievances, rather than valid concerns. The team at Zenith Engineers Inc. has a high level of professional ethics and integrity. Zenith's management team had explained to us early on in the project, the strict adherence to code and compliance was paramount throughout the project. If Zenith compromises to satisfy unsatisfied clients, the building will end up being non-compliant and more importantly unsafe. We truly appreciate Zenith's commitment to quality and integrity, even if it means earning a few negative reviews along the way, which seem rather unfair to them as they are simply doing their job. I am extremely satisfied with the professional and excellent work the team at Zenith Engineers Inc. provided us and will hire them in a heartbeat for all our future structural and/or seismic engineering needs. Thank you Senthil, Ryan and the Zenith engineering team for your professionalism and support. It was our best decision to work with you and experience such high standard of professionalism, work ethic, and integrity.

After having used Zenith for multiple projects in the last few years, looks like it's finally time…read moreto look for someone else for the next one. We started using Zenith because of its responsiveness and effectiveness when it came to structural design. With them as part of our team, we were able to keep up with the City submittal and response timelines we had set. Fast forward to today, and we can't get a hold of anyone. When we do, it's always an excuse for why they didn't respond, without a resolution. We sent them the last City comments 30 days ago and have yet to get anything viable to re-submit back to the city. Given that this is a 30-unit hotel project, going with a different firm now will mean a complete re-design of the project; an absolutely painful exercise that will set us back months. Zenith knows that. So it's absolutely shameful for them to act in a way that would even suggest that our only choice is to get the entire project re-designed by another firm just to have it keep moving forward. So much for "we respond to emails within 30 minutes and always answer phone calls" as outlined on one of their online profile. Knowing how we were treated on this round of City comments and the fact that the entire company seems complacent about what they try to embody in their rhetoric, I would stay away for any future project.

We purchased an older, fixer upper and needed an engineer to look at the foundation and structural…read moresupport beams. SF Bay sent over one of their engineers whom I found to be extremely knowledgeable and presented us with options on how best to deal with the situation. We were so impressed that we hired them when it was time to do a large addition and remodel to the house. Marcus, the business owner, is an experienced engineer who really knows his trade. During the design process he worked hard to accommodate my "wish lists" that I kept adding to (yikes!). At the same time, he advised me on things I should consider in order to keep costs down. I always felt he had my interests at heart, while at the same time he was doing what was necessary to meet codes, so we could avoid problems during construction and inspections. While engineers and architects seem to be really busy these days, SF Bay's turnaround time is reasonable, and when you need something in a hurry, they try their best to accommodate. This is a top notch engineering company that charges modest and fair pricing for doing excellent work. If you are lucky enough to come across them, don't hesitate, just hire them and you will be glad you did.

Initial correspondence was very responsive and professional, and he showed up punctually. He climbed into the attic with us, assessed the situation in detail, provided us intensive education and feedback about our (old) roof, patiently answered our questions in a respectful and professional manner. Mr. Um also confirmed our own assessment of needed structural wall repair and provided us with a detailed, actionable remediation plan and a clear drawing. The recommended plan was aligned with what we expected it to be (based on our non-expert, but intensive research). In addition, Mr. Um educated us with additional finer details of what a successful repair would look like. We had follow-up questions regarding the repair plan / drawing, which Mr. Um patiently answered in detail, addressing all of our questions completely. Overall, Mr. Um's ability and willingness to go into objective detail was the key element that inspired confidence and provided peace of mind.

I was lucky to have the experience of working with Lokesh and ProStruct Engineering. Lokesh…read more(project manager) always answered quickly to all communications in a clear and responsive way. Additionally the output from the structural engineers was efficiently shown in a virtual meeting describing exactly what changes are required and they worked with the contractor to find the most cost-efficient design.

After the plans were released and payment was made Lokesh remained very responsive to requests as they come up. I would definitely use Prostruct again if I have another structural engineering project.

After dealing with a basement flood and running a fan and dehumidifier extensively I noticed…read moreseveral cracks in a support beam. It's possible that they'd been there for a long time, but I uploaded the photos to Claude and it strongly recommended getting a structural engineer to assess the damage. I put out several inquiries and ProStruct responded very quickly. I had a free phone consultation with Irvin Chua of ProStruct and he said that he could have an engineer assess the cracked beam and to look for any other sources of damage. Note, that one will need to pay upfront ($875 is their standard fee), which gave me some pause but moved forward as there didn't look to be many structural engineers with a Yelp presence. Irvin arranged for their engineer, Francis, to make a site visit. Francis was professional and confirmed that the foundation and support beams all were in good shape aside from the crack. He went over his recommended repairs and noted that a handyman could handle it and we didn't need a contractor, which saved us money. The report provided was clear and detailed and the handyman had no problems following the recommendations. Repairs are now complete and we have peace of mind that our housing support is solid again.
