What our clients say

Jorge Charneco, AIA, NCARB, President & Managing Principal
Miles Architecture
Competent. Thorough. Collaborative. These are three characteristics of ZFI Engineering. For the past 20+ years, they have been a trusted and collaborative partner. During this timeframe, the bulk of our work has been on atypical design challenges where ZFI’s ability to solve complex, technical problems has been instrumental in our ability to meet each client's mission and vision for their project. ZFI's focus on the project's best interests paired with earnest feedback has led to innovative solutions that meet our client's needs and their budgets. The relationship I have with ZFI Engineering serves as a benchmark on how I would like our firm to collaborate with all of our consultants.

Working with ZFI Engineering over many years, we have developed a great working relationship. They are readily available to answer questions, and consistently meet our - often tight - deadlines. They provide clear, concise communication surrounding our structural evaluations, along with detailed reports surrounding budget costs and prioritization of work. Simply put, they are experts in their field. I have and will recommend them 100% of the time. We look forward to many more years of working with ZFI Engineering for our structural evaluation needs.
Todd Gralla, Principal
Populous
ZFI Engineering provides high quality technical expertise in a timely manner and their knowledgeable engineers find and propose alternative solutions for challenging projects. Their communication is timely with response time in hours rather than days. We are 100% confident in their work and their engineering recommendations. I would definitely recommend ZFI Engineering.
Chris Burnett
Burnett Construction
What I really like about working with ZFI Engineering is their ability to understand the built environment. They get what works on site and are good at working through issues and solving problems. ZFI is exceptional at applying a sense of reality to projects, and they work around problems that pop up. They are professional and have a good knowledge of engineering. ZFI goes over and above to find out what the problem is and not superficially addressing the problem. I have and will continue to recommend ZFI Engineering.
Alex Jennings
Skybridge Development
When we needed a structural engineering partner for an industrial warehouse evaluation, we were introduced to ZFI—and they delivered from day one. They responded quickly and worked around our tight schedule with ease. What really sets ZFI apart is their creative problem-solving mindset. It’s never about whether something can be done, but rather how to make it happen. Their team brings a practical balance of deep expertise and common sense. They avoid over-engineering, focusing instead on smart, effective solutions that make sense in the real world. The partners are highly engaged, accessible, and responsive. Throughout the project, I saw firsthand their strong team dynamic and genuine camaraderie. ZFI is responsive, friendly, and solution-oriented—an outstanding partner that adds real value to any project.

Collaborative team players are what make projects successful. Working with ZFI is like working with an extended part of our team. They provide valuable feedback and direction during design and construction. Their outside-the-box structural solutions allow us to move forward on the project. ZFI has been extremely responsive throughout the entire project. I look forward to working with them on future projects.
