Clark Bros Inc.

Clark Bros. Inc. (CBI) is a licensed general engineering contractor and full-service EPC (Engineering, Procurement & Construction) firm headquartered in Central California.

Since 1960, we’ve delivered complex infrastructure projects across the western United States with an emphasis on quality, safety, and client collaboration.

We specialize in heavy civil construction, high-voltage electrical infrastructure, and renewable energy projects including solar, wind, battery energy storage (BESS), and substation work.

As a nimble and privately held company, CBI offers clients a streamlined EPC experience from preconstruction through commissioning. Our in-house teams self-perform earthwork, concrete, electrical, and structural scopes, enabling greater control over schedule, safety, and cost.
