ZENITH ENGINEERS

Client-Centric Engineering

Serving Clients Across The U.S.

Zenith Engineers Inc. is a full‑service structural engineering firm partnering with general contractors, specialty contractors, developers, manufacturers, and architects to deliver buildable solutions on active job sites. We focus on delegated design, construction engineering, and structural support for commercial, industrial, water treatment plants, wastewater treatment plants, modular, and multifamily projects, so your team can build faster and with confidence.

Zenith Engineers Inc. provides structural engineering services for commercial, industrial, multifamily, and modular projects, with a focus on the scopes contractors carry after a bid is awarded. Our team develops delegated design packages, temporary works designs, anchorage calculations, and shop drawings that account for field conditions and schedule milestones. We also support water and wastewater treatment plant projects with pipe support design and structural analysis. From proposal through construction administration, our engineering team works to respond to RFIs, review changing site conditions, and turn around revisions so crews can keep work moving and project teams can plan the next phase.

Founded in 2009, Zenith is a firm built around in-field construction engineering. Our team has grown from two engineers to forty engineering professionals who work with general contractors, specialty contractors, developers, manufacturers, and architects on projects across the country. Zenith placed No. 446 in 2018 and No. 213 in 2019 on the Inc. 5000 list of fast-growing private companies in America. As a structural engineering company, we focus on practical, buildable details, clean submittals, and responsive communication. Our growth has been driven by long-term relationships with clients who rely on our team as an extension of their own project staff.

Our engineers partner with general contractors, trade partners, developers, and manufacturers on everything from first‑time projects to large, recurring programs—always with field‑ready, code‑compliant solutions.

Our mission is to raise the construction industry’s expectations of structural design – faster submittals, constructible details, and responsive support from concept through close‑out – so projects stay on schedule and on budget.

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.

Frequently Asked Question's

Zenith Engineers Inc. focuses on commercial, industrial, water and wastewater treatment plant, modular, and multifamily projects, providing delegated design, construction engineering, and structural support for general contractors, specialty contractors, developers, manufacturers, and architects.

Through the contract documents, the engineer of record assigns design of specific components, such as stairs, railings, steel connections, or equipment anchorage, to a contractor or supplier, who engages a licensed engineer for stamped calculations. Requirements vary by jurisdiction.

Zenith follows four steps: a proposal based on the scope, a site visit when field conditions call for review, engineering of the calculations, drawings, and details, then client review and approval. Our team also provides construction administration on applicable projects.

Zenith is headquartered in Pleasanton, California, with offices in Woodland Hills and Sacramento, and serves clients across the U.S. Because engineering licensure requirements vary by state, contact our team to confirm availability for your project location.
