Electrical and controls engineering behind reliable critical infrastructure.
Canfield Engineering & Integration is a family-owned and operated EI&C firm. We carry water, mining, industrial, and power projects from the first study through design, PLC/SCADA programming, commissioning, and on-call support — one accountable in-house team, start to finish.
Projects delivered across the Southwest

Team-driven & locally staffed · Responsive on-call support · We answer the phone, show up in the field, and stand behind our work.
One team. Concept through commissioning — and beyond.
Most facilities juggle a designer, a programmer, a panel shop, and a commissioning agent. Canfield is all of them. Because the same firm designs the facility, writes the control logic, and commissions the system, we retain deep knowledge of your standards and assets over time — fewer vendors to coordinate, less risk at startup, and a consistent EI&C approach across every site.
Assess → Design → Panel Oversight → Program → Commission → Startup → On-Call Support
