What BEI Construction does

BEI Construction, Inc. is a privately held, union-based construction services firm founded in 1988 and headquartered in Alameda, California. The company delivers end-to-end design/build and EPC services across four integrated service lines: renewable energy construction (solar PV, wind, battery energy storage systems, substations, and EV charging infrastructure), electrical construction (power distribution, system upgrades, medium voltage, transmission and distribution), civil construction (underground infrastructure, grading, directional drilling, foundations), and technology infrastructure through its BEI Connect division (structured cabling, AV, security integration, and wireless for data centers and enterprise facilities). The TierFour Training sub-brand provides BICSI certification preparation (RCDD, DCDC, OSP, NTS). As an IBEW, LIUNA, and NECA signatory contractor with multi-state licenses (California, Nevada, Arizona) and IRA compliance for federal incentive projects, BEI is qualified to bid utility-scale renewable and storage work across the Western United States.

The company's revenue model is project-based professional services delivered under lump-sum and cost-plus arrangements, priced through competitive bidding and direct negotiation per engagement. The go-to-market is enterprise field sales targeting developers, EPCs, and investor-owned utilities for utility-scale renewable energy, and targeting enterprise technology, healthcare, education, and commercial real estate clients for technology infrastructure work. More than 50% of annual revenue comes from existing client relationships, reflecting high contract retention. Customers span named enterprise logos including Engie, SOLV Energy, Energy Vault, Ameresco, Calpine, GridStor, NV Energy, PG&E, Twitter, Uber, HP, Block, NBC Universal, Stanford Health Care, and UCSF. Sister company Blymyer Engineers (17GW of solar designed) provides integrated engineering for design/build work, reinforcing the single-source delivery model. Documented operational scale includes 2GW+ of solar/storage/substation projects, 274MW/1.1GWh of Tesla Megapack BESS, 200MW+ of solar, 50+ MW of wind, and a 1 million+ work-hour safety record without a recordable incident.
