Fast, efficient, quality work that flew with high flying colors through the City Permits Department in one pass. I was impressed by them in all the ways our project worked out and hired them again for a very consequential project. Their thoroughness impressed me and my contractor ("These guys sure are covering all the bases brilliantly", he said of them). We wanted to lift up the ceiling of our kitchen and family room. Because the previous framing work was lacking and because we recently replaced our roof and installed a solar system with increased wind exposure, A1F1 explained we needed to install a big beam with a pier in concrete under the house. They provided all the drawings and calculations documentation needed for the City to approve again at first pass. Work is now under progress, and I have been at awe on how everything is working totally like clockwork. Highly recommended!

Anthony, from A1F1, took time out of his busy schedule to come out and look for almost no cost. He was on time, professional, and extremely knowledgeable. He actually advised me about another wall bordering my kitchen, and told me I could remove that wall since it wasn't load bearing. So now, I will remove 2 walls, and have a totally open floor plan. Can't say enough about the guy. If you are looking for a structural engineer, believe me, u won't get a better value.

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.

She even caught two other issues during the walkthrough that I wouldn't have noticed otherwise. I really appreciate the honesty and the extra effort. Great experience!

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.

DO NOT USE THIS COMPANY -- terrible communication and shady tactics…read more I reached out to ProStruct Engineering for a simple onsite structural evaluation at my home in Danville. They sent a 10-page contract and demanded the full $1,100 upfront the same day, before any work was even scheduled. After I signed and inquired, I asked the project manager multiple times for a firm date when the engineer could come out for the survey. Instead of giving a straightforward answer, they used clear delay tactics and kept putting me off with vague responses. When I finally decided to cancel before any site visit or report was started, their own contract (Section 5.5) clearly states I should only owe a $500 "setup fee." Yet they are now treating it as if I owe the entire $1,100. This is a classic "pay us everything first, then we'll drag our feet" operation with a heavily one-sided contract designed to trap customers. Save yourself the stress, the risk of a lien on your house, and the endless runaround. There are plenty of other licensed structural engineers in the Bay Area who actually communicate and don't play games with scheduling. Would not recommend. Proceed with extreme caution.
