Electrical Engineering

Our qualified team of electrical engineers, electrical designers, CAD operators, and commercial electricians on the West Coast has designed and engineered numerous high-profile projects in California for more than 50 years.

Electrical Construction

We’ve taken thousands of projects from design to full-service electrical construction and installation since 1962. On-time and under budget, we continue to offer high-quality services for all our commercial and industrial projects, from lighting and communication systems to environmental controls and alarm systems.


Our Design Build strategy simplifies the process. We save time and money by providing a single point of responsibility for all services, which minimizes risks for the project owner, and consolidates construction schedules.
