Testimonials

Zenith handled delegated design on one of our commercial builds. Submittals came back clean, the details were workable in the field, and when conditions changed they turned revisions around quickly. Easy firm to coordinate with.

David K California

enith did the code analysis and structural calcs on a treatment plant retrofit for us. Documentation was thorough and their team was responsive when inspections needed follow-up. We'd use them again on plant work.

Linda S Vernon, CA

We acquired a 1960s tilt-up portfolio across the Bay Area and needed retrofit work on eleven buildings before lease-up. Zenith handled the code analysis at acquisition, then carried the same team through full design and construction administration. Having one firm own the whole arc shortened our underwriting timeline by months and gave us defensible numbers to take to capital. They understand what developers actually need from an engineering partner.

Peter V. Santa Clara, CA

Zenith Engineering is my “to go” firm for all my engineering needs on my projects. As an Interior Designer, I always look for professionals I can partner with to deliver the best service to my clients. I know I can always rely on Zenith for their professionalism, prompt response and excellent customer service. I’ve mostly worked with Yisilayin and he is absolutely amazing!

Alina D. Castro Valley, CA

It is hard to find a good, responsive engineer. From beginning of quote to approval all through inspections, Yisilayin and zenith engineers was phenomenal! Also wanted to mention Irina the office manager, Irina was great, she coordinated everything perfectly, thank you Irina! Every small obstacle on the way was solved and corrected on the same day! The effort they make to make sure their clients are satisfied is definitely the kind of customer service you are looking for when hiring an engineer. Thank you zenith, will use you guys in the future again for sure! Highly recommended

Jonathan E. Newark, CA

SB 326 compliance was going to be a logistical mess across our twenty-eight-property portfolio. Zenith scheduled, inspected, and reported on every balcony and exterior elevated element on a timeline that worked around tenant access, and the deliverables were clean enough to hand to our boards without rework. We've kept them on retainer for ongoing structural questions across the rest of the portfolio. Yisilayin is extremely knowledgeable, polite, responsive, and very thorough. I appreciate that he looks for the best solution to every situation we encounter on a project. Irina and Julie are definitely doing a wonderful job at keeping the projects running smoothly.

Rachel T. San Francisco, CA

We brought Zenith onto a 240,000 sq ft industrial expansion where field conditions kept shifting, and they kept up. Their delegated design submittals came back clean, the details were already priced for the field, and our subs stopped flagging structural questions because Zenith was usually two steps ahead. They work like contractors who happen to be engineers — which is what we needed.

Marcus H. Portland, OR

Zenith engineered a run of modular units for us. Their drawings worked with our production sequence and the field-side details held up at install. Construction administration was hands-on when we had questions from site.
