Celebrating 38 Years of Purposeful Construction

For nearly four decades, BEI Construction has grown through innovation, long-term partnerships, and a consistent commitment to how electrical and telecom projects are designed and built.

What began as a focused electrical contractor has evolved into a diversified construction portfolio spanning solar, energy storage, wind, substations, EV charging, workforce training, fossil fuel power plants, hydropower facilities, industrial operations, and water-resource infrastructure. Each expansion reflects a deliberate response to industry needs, grounded in safety, technical excellence, and client success.

Origins and Early Expansion

BEI Construction was established in March 1988 as a focused extension of Blymyer Engineering, Inc., bringing together engineering expertise and hands-on construction delivery under one integrated model.

This relationship enabled BEI to provide comprehensive industrial and commercial solutions with a strong emphasis on electrical and telecom projects. From the beginning, close coordination between engineering and field teams shaped BEI’s approach, ensuring that projects were designed with constructability, performance, and long-term reliability in mind.

In 2003, BEI built its first solar project, marking the start of its involvement in renewable energy. While the market was still emerging, BEI recognized solar as a natural extension of its electrical expertise. Solar construction soon became a core capability, particularly for complex commercial and utility-scale projects.

As experience grew, BEI expanded into additional energy-related sectors, including wind, battery energy storage (BESS), substations, and EV charging. These capabilities allowed the company to support a broader range of renewable and power infrastructure solutions while continuing to advocate for reliable, forward-looking energy systems.

Growing with Purpose

BEI’s growth has been driven by a combination of expanding client needs and deliberate investment in people, capabilities, and long-term partnerships. As organizations scaled their operations, BEI grew alongside them, while also strengthening its expertise to support more complex energy and infrastructure projects.

Demand for BEI’s services extended beyond Northern California, driving expansion into Southern California, Arizona, and Nevada. In parallel, BEI began supporting U.S.-based clients as they expanded internationally, delivering design-build network cabling and technology infrastructure in Australia, Canada, Ireland, Norway, and Japan.

Whether supporting domestic or international work, BEI applies the same construction rigor, coordination, and performance standards. By 2024, BEI had grown to more than 200 employees, supported by 22 IBEW union partners, and transitioned into a new headquarters designed to support a larger, integrated team.

Leadership Focused on Long-Term Value

BEI’s current C-level leadership is deeply rooted in the company’s history. Each executive began as a principal in 2005, bringing a long-term perspective on the industry, the organization, and BEI’s strategic direction.

  • Dom DiMare, Chief Executive Officer: Leads long-term strategy, company culture, and partnerships with a focus on safety and sustainable growth.
  • Gary Chelini, Chief Operating Officer: Oversees operations and field execution, driving consistency, quality, and accountability across projects.
  • Natu Tuatagaloa, Chief Revenue Officer: Leads business development and client strategy, aligning growth with BEI’s technical capabilities.

Looking Ahead

Thirty-eight years after its founding, BEI continues to evolve and expand. In 2025, a partnership with Watson Electric, a woman-owned electrical contractor with more than 20 years of experience supporting utilities and public agencies across California, strengthened BEI’s technical capabilities and expanded its service portfolio.

Growth at BEI has never been about chasing trends. It has been about adding capability with intention, reinforcing the structure before building higher.

That approach positions BEI for the next chapter of energy and infrastructure construction.
