Eichleay is an engineering, procurement, and construction management firm serving industrial, manufacturing, and sustainable energy facilities. Founded in 1875 and now in its fifth generation of family ownership, the firm has spent more than 150 years of technically complex projects for the process, power, and manufacturing sectors.

From its corporate office in Larkspur, California, Eichleay serves clients throughout the Bay Area, the West Coast, and beyond with full project delivery. The firm oversees multidiscipline engineering and design, procurement, and construction management in house, which prevents the coordination gaps that come from splitting a project across multiple suppliers and keeps the same team involved from concept through completion.

Eichleay focuses on fast-track work that involves many engineering disciplines at once. Clients trust the firm for detailed engineering, facility upgrades and expansions, capital project support, and hands-on construction management. Projects are organized, staffed, and managed by experienced in-house professionals rather than handed off between vendors.

With its mid-sized scale, Eichleay provides large-firm capabilities while maintaining the responsiveness and long-term client relationships of a smaller organization. A focus to safety, quality, and environmental responsibility is built into how the firm operates.

In addition to the Larkspur corporate office, Eichleay maintains locations in Orange, California, Ferndale, Washington, and Billings, Montana.
