Great West Drilling, Inc.

Great West Drilling, Inc., a self-certified small disadvantaged business based in Fontana, California, provides drilling services, borehole instrumentation, and geotechnical investigation work to federal water management and civil-works agencies as a prime contractor (96% of recent awards) under total small business set-asides.

The vendor's customer base concentrates heavily on water infrastructure and dam safety work. The top four funding organizations account for 65% of awards by count and 92% of combined potential value: the Department of the Army Corps of Engineers Engineering District Sacramento (2 awards, $9.5 million combined potential value) leads the dollars, while the Department of the Interior Bureau of Reclamation (10 awards, $1.7 million) leads the award count. The Corps Engineering Districts Los Angeles and a broader Army Corps entity round out the active customer set. Representative prime work includes a $342,408 firm-fixed-price purchase order from the Bureau of Reclamation for the Shasta Drilling Lens project (awarded September 2024), delivering Becker Penetration Testing investigations and boreholes to support liquefaction analysis of Shasta Dam embankment materials; a $342,924 purchase order from Reclamation for 2021 Starvation Dam in-place borehole testing in Colorado (awarded September 2021); and placement under an Army Corps Indefinite Delivery Contract (W9123720D0010) for civil-works drilling. The vendor's NAICS profile centers on site preparation contracting (6 awards), testing laboratories and services (4 awards), and geophysical surveying (3 awards), with PSC codes clustering around well drilling and exploratory work, geophysical and geotechnical analysis, and quality control and inspection services. Activity is sparse and episodic — one to two awards per year in recent years, with a combined potential value of $12.9 million across 23 total awards since 1996 and only $3.5 million obligated to date. The vendor holds one subcontract role, subcontracting to Stantec Consulting Services Inc. on a FEMA-USACE Seismic Study Support drilling task in California (January 2026).
