Interstate Drilling Services LLP

Interstate Drilling Services LLP, a woman-owned small disadvantaged business based in Grand Forks, North Dakota, provides geotechnical drilling, soil boring, and drill rig rental services to the U.S. Army Corps of Engineers as a prime contractor, operating exclusively under USACE IDIQs and delivering work across the Upper Midwest. The vendor competes on both partial and total small business set-asides and full-and-open delivery orders, with 100% of its recent award footprint concentrated in the prime posture.

The Army Corps of Engineers accounts for 98% of recent awards and substantially all dollar value. The vendor's top customer by dollar concentration is the Department of the Army Corps of Engineers St. Paul District (80 awards, $6.3 million combined potential value), which issues delivery orders for geotechnical drilling within its geographic boundaries spanning Minnesota, North Dakota, and Wisconsin. The Department of the Army Corps of Engineers Engineering District Omaha (2 awards, $543 thousand combined potential value) and Engineering District Savannah (8 awards, $100 thousand combined potential value) represent secondary volume. Recent representative work includes a $32 thousand firm fixed-price delivery order issued February 10, 2026, by the USACE St. Paul District for geotechnical drilling at the Grand Encampment dredge material placement site in Wabasha, Minnesota; a $17 thousand delivery order from September 1, 2025, for a soil boring program and cone penetrometer testing in Benedict, North Dakota; a $25 thousand partial small business set-aside delivery order from July 8, 2025, for geotechnical drilling at Orwell Dam near Fergus Falls, Minnesota; and a $26 thousand delivery order from March 4, 2025, for drilling services at the OHB Ring Levee in Horace, North Dakota under the Western Area IDIQ Option Year 1.

Interstate Drilling Services holds five primary indefinite delivery contracts with the Army Corps of Engineers. The largest is a $1.86 million partial small business set-aside single-award IDC with the USACE St. Paul District awarded January 12, 2023, running through January 31, 2026, which specifies rental of truck-mounted and all-terrain track-mounted geotechnical drilling rigs with operating personnel, soil boring and sampling using hollow stem auger and mud-rotary drilling techniques, cone penetrometer testing, subsurface exploration, and geological data collection across the St. Paul District's Western Area (within 50 miles of Fargo, North Dakota) and Eastern Area (Mississippi River corridor between Hastings, Minnesota and Guttenberg, Iowa). A $1.2 million total small business set-aside IDC awarded August 3, 2022, by the USACE covers geotechnical drilling services and equipment rental across the Midwest region through January 31, 2024. Three additional USACE IDIQs—W912ES10D0006, W912ES04D0001, W912ES15D0001, and W912ES18D0002—collectively generate 87 task orders and $1.84 million in combined potential value. The category concentration reflects the vendor's core capability: 71 awards fall under NAICS 238110 (Site Preparation Contractors), 54 under NAICS 213111 (Drilling Oil and Gas Wells), and 26 under NAICS 237990 (Other Heavy and Civil Engineering Construction). PSC coding aligns similarly, with 60 awards under equipment lease or rental for special industry machinery and 51 under natural resources conservation-other work.

Activity has remained flat to declining over the past five years—nine awards in 2022, eight in 2023, nine in 2024, six in 2025, and one in early 2026—with individual delivery order values typically ranging from $5 thousand to $132 thousand. Combined potential value across all 177 prime awards is $15.3 million, with $4.3 million obligated (28% realization), indicating that task orders are issued incrementally against standing IDIQs rather than as up-front commitments. The vendor operates exclusively as a prime contractor; no subcontract footprint is present in the source data. Work is performed at distributed locations across the Upper Midwest, with place-of-performance sites including Wabasha, Minnesota; Fargo, North Dakota; Fergus Falls, Minnesota; and Arcadia, Wisconsin, reflecting the geographic scope of the USACE St. Paul District's civil works missions in flood control, navigation, dam construction, and water resource management.
