South of Phoenix. Desert floor. 105°. Full send.

The CEC crew is out here doing topo survey work for a wastewater design project in the desert Southwest — GPS rovers, ground control points, drones in the air. The whole setup.

Yes, we work in Arizona. Yes, it’s hot. No, we would not have chosen June for this. (January is right there on the calendar. Just saying.)

This is for a long-time client we’ve been building with for years — the kind of relationship where you don’t have to explain the scope twice and everyone shows up knowing what needs to get done. That’s the work worth doing.

If you’re in the Phoenix area, live for this kind of field work, and want to be the guy setting ground control in the desert instead of sitting in a cubicle — we should talk.

South Dakota state Senator Sydney Davis stopped by today and place a sign in our front yard! We’ve always supported her and appreciate the good job she does being a pro growth legislator for the state of South Dakota.

Union Crossing keeps taking shape along Sioux Point Road, and CEC is proud to serve as the Engineer of Record behind this future neighborhood coming out of the ground in North Sioux City.

Always good to see design work move off the plans and into the field.

Boots Dirty or Desk Duty?

North Texas Municipal Water District | Working with ARCO/Murray

Some engineers are built for the office…
Others are built for this. 👇

Not afraid to jump in the trench--even if it is 25-ft deep!

The guy throwing the thumbs up? He’s one of ours—a young engineer and Assistant Project Manager who’s not afraid to trade the desk for the field. In fact, our foremen are already joking about stealing him for QA/QC work.

At CEC, we don’t just design it—we build it. Our engineers are wired differently. They understand how things actually go together in the real world because they’re out here living it.

If you’re the kind of person who:
✔️ Wants to see your work come to life
✔️ Doesn’t mind getting your boots dirty
✔️ Likes the idea that no two days look the same

…we should talk.

We’re growing—and always looking for:
• Project Managers
• Project Engineers

Whether you’re working somewhere else and ready for something different—or even a company owner thinking about the next chapter—we’d love to connect.

Fence went up last week… which means we’re getting close.

Final touches are going in now before we put the system into operation.

This one started like most good projects—trying to solve a problem. In this case, it was our own. Our team designed it, built it, and worked through it the same way we would for a client.

We’ll get into more detail later, but there’s more to this than just putting panels in the ground. The way you design, lay it out, and structure it financially matters. Done right, it’s not just about producing power—it’s about long-term savings and taking advantage of tax opportunities that aren’t always obvious at first glance.

We try to think that way for our clients every day… figured we should do it for ourselves too.

More soon when we flip the switch.
