Build with Certainty

Industrial construction presents a range of challenges—from compressed schedules and complex trade coordination to unpredictable site conditions. Off-site manufactured solutions bring that work into a controlled environment, enhancing schedule reliability, quality, and overall efficiency. When clients choose our full turnkey option, they benefit from seamless integration of planning, design, fabrication, and installation. Every build is backed by decades of deep electrical expertise for a strategic assembly. The result: fewer delays, increased productivity, minimized downtime, and greater confidence that every piece will work as intended, right from the start.

Industrial Control Panels

With over 30 years of experience building UL508a-certified industrial control panels, we can bring superior, repeatable results to your facility. Leveraging strong relationships with suppliers, these panels meet best-in-class global quality standards. Designed by professionals with deep control system expertise and built by teams with strong electrical backgrounds, every panel is engineered to not just meet code—but to perform reliably in the real world. The result is a high-quality, fully tested panel that integrates seamlessly and supports long-term system performance.

Modular Solutions

Our modular electrical houses (e-houses) offer you a plug-and-play solution to meet your power distribution needs. These pre-assembled and pre-tested modular power distribution stations offer rapid, flexible power supply in remote or hard-to-access locations and provide temporary power during short-term projects. Designed to fit into your broader system—not as an afterthought—our e-houses help you stay on schedule and fully powered, when and where you need it.
