They’re the best firm I’ve ever worked with. They’re so easy to work with. I never get pushback anytime I want to make changes. They have such a good attitude about it. I never feel like I’m putting them out, or hear “This is going to cost more money”, and I appreciate that. I would recommend them to any jurisdiction.

Ethics and values come from the top. Bennett’s leadership team genuinely cares and treats every employee, partner, and client with respect. I have never felt more of a team than I do here.

BEN|EN staff is like family to each other. We are a very tight-knit group that is cohesive and productive, but we also have fun at many company-sponsored and outside events. It’s also worth noting that the company not only shows compassion to employees in times of need but also to other industry-related folks in our networks. Anonymous Employee Survey

BEN|EN’s responsiveness as well as their ability to think outside the box is what I like best about working with them. Leo was able to expedite the processes especially working with Caltrans on a federal project. He was able to call specific people and navigate those waters. That was worth its weight in gold!”

The diversity in our office comes from every single individual in our office being willing to work with people of different gender, nationality, age group, and ethnicity and has nothing to do with a mandated corporate policy, making our office a more organic setting with great people to work with.

Bennett Engineering Services worked on the design-build team for the Upper Banner project for the Nevada Irrigation District. The design-build team really listened to our concerns and was very responsive. Using the design-build delivery process functioned exceptionally well—the project has been on time and on budget.

The process was streamlined and the communication, responsiveness, and quality were excellent.  I was very pleased with the level of service. I never had to wait for a response. When the project engineer was going to be unavailable, he provided information ahead of time and had another engineer ready to respond if he couldn’t.

“A lot of firms will do plans the way they are used to, but Bennett Engineering said, “Tell us how you want the plans to look and we’ll make them the way you want them.” No one has ever asked us that! So the end product was something we were very familiar with. It looked like we did it in-house and our workers will not have any problem deciphering what the drawings mean or finding information in the future.”

The work Leo Rubio did for us with the Caltrans Relinquishment project was stellar.  He really did one-of-a-kind work.  We were able to build Streetscape Phase 1 because he got it moved right through the Commission.  The whole thing was done in 18 months.  It was amazing.

My favorite thing about working with Bennett Engineering is the level of commitment to their work product. They take pride in their work and want to see a successful project, which is very apparent from working with them on the Del Paso Boulevard project. Leo Rubio will bend over backwards to find solutions for us and think outside the box.”

Leo and his team are very responsive to us.  Leo’s knowledge of the Caltrans process has been a huge asset for our project team because he’s been able to push some things through that would often take longer.  For me, that’s a very important aspect to this project – getting through the Caltrans process – as well as his knowledge of the people up there.  It’s helped move things along.”

As the project manager of the Highland Reserve North Pump Station project, I appreciated BEN|EN’s pursuit of new and innovative solutions to hydraulic problems while staying within a limited project budget.

Bennett Engineering was the unanimous selection due largely to their breadth of municipal experience service, very positive record, and strong track record of success obtaining funding from various State and Federal agencies. Bennett Engineering provides engineering services to several agencies in Butte County, including the City of Biggs. Bennett is highly regarded by area cities and the Butte County Association of Governments and by local Caltrans staff.

It shows how private and public can work together and come up with a really successful project for the public.
