Working with Irvin at Prostruct Engineering was a breath of fresh air. 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.

She inspected our house as well as its architecture/design plans and then turned out a report in a few days. She then accompanied me to the city to present her findings and was instrumental in fast-tracking the whole process. The permit process is utterly new to me and one of my take-aways has been that it's critical to have a knowledgable expert who can do solid analysis and then communicate effectively with the city's Building and Planning departments -- I highly recommend her.

Vesna Obradovic did a great and affordable job reviewing our house's plans to answer some questions…read morewe had about structural walls, foundations, remodel possibilities, etc. I believe it was $200 to come by the house, where she took the time to inspect and answer all our many questions, and then after we'd gotten the house plans from the county, she also reviewed the old construction plans and made comments. Later we asked her to be the structural engineer reviewer on our house remodel, which she turned around in less than 24 hours, provided paperwork for filing for permits, etc., all for $230. Vesna was a big find -- I've been quoted structural engineering fees of $1000+ & taking weeks, for the kind of work she efficiently does in days for much less money. I'd recommend her for any residential construction reviews.

Marc examined the foundation and surrounding land conditions to determine the best options. He was already familiar with our unique ecosystem (Sand Hills area of San Lorenzo Valley), and suggested we reinforce the existing concrete slab with a perimeter foundation. Since he doesn't work with or recommend contractors, I was confident that his goal was to help his clients rather than "upsell" us or give work to his friends. We had the work done shortly after Marc's assessment, which stopped the cracks from getting worse. He's a pleasure to work with and seems to genuinely enjoy investigating and working out clients' land/foundation issues. I'd highly recommend Terra Firma for anyone who needs unbiased, expert advice from an environmental engineer.
