What Lasar Underground Construction, Inc. does

Lasar Underground Construction, Inc. is a family-owned underground infrastructure construction company headquartered in Fresno, California, founded in 1994 by Shawn Griswold. The firm provides installation, repair, and surface restoration services for telecom, power, water, and sewer infrastructure across Central California, operating as both a prime contractor on public works projects and a subcontractor to general contractors. Its customer base includes telecommunications carriers (AT&T, Frontier, CVIN), rail authorities (California High-Speed Rail Authority, BNSF Railway), utility companies (DTE Energy, ConEdison), and municipal governments (City of Fresno, City of Clovis).

The company's core technical capabilities center on horizontal directional drilling (HDD), vacuum and hydro excavation for utility daylighting, variable-moment vibratory hammer piling for rail right-of-way work, and high-early-strength concrete mixes that reach 3,000 PSI in 24 hours. Service lines are organized around five core pillars: directional drilling (HDD), fiber and telecom builds, underground utilities (conduit, water, sewer/storm laterals, utility crossings), surface restoration, and maintenance/emergency response. Lasar self-performs the complete OSP civil scope on broadband middle-mile builds at a stated production rate of approximately 500 buried service drops per month, and has delivered more than 120 miles of fiber substructure across the Central Valley, including eight named utility relocation segments spanning Fresno, Kings, and Tulare counties for the CA High-Speed Rail program.

The business model is project-based B2B construction services with custom quote-based pricing and no publicly disclosed rates. Revenue is generated through competitive bidding on public works, direct negotiation on private contracts, and long-term maintenance agreements with telecom carriers. Lasar holds in-house regulatory credentials that reduce subcontractor dependency, including a C-31 traffic control license, an A-license for road encroachment permits, and Cal-OSHA T1 trenching certification. Pricing is quote-driven, billing follows project and multi-year contract cadences, and the company offers no self-serve or retail distribution channels. The firm is family-controlled by the Griswold and Gregory families with no disclosed external equity investors.
