Dune Technologies LLC

Dune Technologies LLC, a Holland, Michigan–based small business sole proprietorship, manufactures and distributes specialized marine research and hydrologic instrumentation—primarily Acoustic Doppler Current Profiler (ADCP) systems, sonar equipment, and flow sensors—as a distributor and systems integrator for Teledyne Marine acoustic equipment, operating as a prime contractor on 97% of federal awards under total small business set-asides.

Dune Technologies operates across seventeen federal customer agencies with no recurring parent vehicle presence; the vendor competes predominantly on purchase orders under simplified acquisition procedures and total small business set-asides, with no GWAC, IDIQ, or BPA footprint in the source data. The company's capability portfolio is narrowly specialized: ADCP procurement and integration (RiverPro 1200 kHz and Workhorse II models), portable sonar systems (Teledyne Seabat T50-P), and flow-rate sensors for hydrologic measurement, oceanographic research, and water resource management. Representative work includes a $284,811 firm fixed-price purchase order from Naval Sea Systems Command (September 2023) for a Seabat T50-P portable sonar system with FlexMode and T-series licenses for uncrewed vehicle integration at Naval Support Activity Panama City; a $51,880 award from the Office of Naval Research (July 2023) for Workhorse II 300 kHz ADCPs; a $35,225 purchase order from the Fish and Wildlife Service Region 3 (March 2026) for a RiverPro 1200 kHz ADCP with Trimaran float vessel supporting the Sea Lamprey Control Program at the Ludington Biological Station; and a $28,430 award from the U.S. Geological Survey Columbia Environmental Research Center (August 2024) for an ADCP supporting endangered pallid sturgeon habitat research.

Customer concentration splits between volume and value. The top five customer agencies by award count account for 63% of awards, led by the U.S. Geological Survey (10 awards, $223 thousand combined potential value) and the National Oceanic and Atmospheric Administration (5 awards, $346 thousand). However, by dollars, NOAA ranks first ($346 thousand across five awards), followed by Naval Sea Systems Command ($285 thousand, one award), and USGS ($223 thousand across ten awards)—a divergence driven by the Navy's single high-value sonar order. The vendor has served the Department of the Interior, Department of Commerce, Department of Agriculture, Department of the Navy, and the Army Corps of Engineers, with NAICS concentration in Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (16 awards) and Instruments and Related Products Manufacturing for Measuring and Controlling Industrial Process Variables (12 awards).

Activity has been intermittent: one award in 2019, one in 2020, three in 2023, three in 2024, and three in 2026 year to date, with combined federal potential value of $1.4 million fully obligated. The vendor carries one named subcontract sub-award—a RiverPro 1200 kHz ADCP delivery under Atlantic Diving Supply as prime (September 2024)—representing 3% of the award footprint. Dune Technologies holds an established track record delivering advanced acoustic and sensing equipment to federal agencies since 2011 and has been selected on sole-source grounds for specialized Teledyne Marine product compatibility with existing agency systems.
