About the company
Jensen Rock & Sand Inc., a Mobridge, South Dakota–based small business, supplies gravel, sand, crushed stone, and related construction materials to federal agencies as a prime contractor (83% of recent awards), with occasional subcontract work on construction and renovation projects. The firm is a for-profit Subchapter S corporation competing in full-and-open procurements without SBA set-aside designations on most work, though recent prime awards include total small business set-asides. Primary NAICS alignment runs to highway, street, and bridge construction (6 awards) and commercial building construction (2 awards), with PSC coding concentrated in miscellaneous construction materials and mineral construction materials in bulk.
Customer concentration favors the Department of the Interior and the Department of the Army. The Department of the Army Corps of Engineers anchors the customer base with 3 awards valued at $95 thousand combined potential value, concentrated in gravel supply and delivery for recreation area maintenance — a $57.75 thousand purchase order for 1,500 tons of North Dakota Department of Transportation Class 5 gravel to the Beaver Creek Recreation Area boat ramp in Linton, North Dakota (set aside for total small businesses, August 2023) and a $36.75 thousand gravel delivery order (July 2022). The Department of the Interior Bureau of Indian Affairs Great Plains Region accounts for 3 awards with $28 thousand combined potential value. The top five customer entities account for 75% of awards, with the Department of the Interior, Bureau of Indian Affairs, and the Fish and Wildlife Service Region 6 rounding out the set.
Award activity is episodic. The vendor placed 1 award in 2018, 1 in 2022, 1 in 2023, 2 in 2024, and 1 in the first half of 2026, with combined potential value of $253 thousand across 12 total awards (prime and sub combined) but combined obligated value of $1.7 million — a signal that actual spend significantly exceeded ceiling values on executed work. One award with $20 thousand potential value reaches ultimate completion within the next twenty-four months. Jensen Rock & Sand operates via two named indefinite-delivery vehicles: IDC 140A1621D0044 and IDC W911SA24D2000, each carrying 1 task order. In its subcontractor role, the firm performs parking-lot repair and courtyard renovation work under Gana-A'yoo Construction Services JV LLC and PMR Services III LLC (awards in October 2024 and May 2024, respectively). SCI reporting shows minimal service-contract activity — a single SCI-reportable subcontract in FY2024 representing 0.4 FTEs — indicating the vendor's federal footprint consists primarily of goods supply and construction purchase orders below the SCI reporting threshold.
