About the company
Humboldt Mfg. Co, an Elgin, Illinois-based small business manufacturer, delivers specialized construction materials and soil testing equipment to federal agencies as a prime contractor under total small business set-asides, with a 110-award footprint spanning four decades and a recent trajectory of one to two awards annually since 2023.
Humboldt manufactures and sells concrete, soil, asphalt, and erosion testing apparatus—including flexural testing systems, triaxial load frames, erosion function apparatus, and modular test kits—alongside replacement parts and support services. Recent representative work includes a $127,451 firm fixed-price purchase order from CDC Pittsburgh for flexural testing equipment (August 2026), a $85,525 sole-source purchase order from the Bureau of Reclamation for an Erosion Function Apparatus using proprietary SRICOS methodology and ASTM-compliant design (August 2026, competitive after market research confirmed Humboldt as the sole commercial manufacturer of a ready-to-use flume-type soil erosion testing device), and a $168,066 purchase order from the Army Corps of Engineers Engineer Research and Development Center for a Material Testing System–U435CEI supporting construction materials evaluation (August 2023). Work spans NAICS 541890 (Other Measuring and Controlling Device Manufacturing) and PSC Laboratory Equipment and Supplies, with secondary concentration in Physical Properties Testing and Inspection.
Customer concentration is diffuse across 44 distinct federal agencies. The top five customers by award count account for 33% of awards but are fragmented: the Federal Highway Administration (11 awards, $104 thousand combined value), the Department of the Army (8 awards, $97 thousand), the Army Corps of Engineers Engineer Research and Development Center (7 awards, $533 thousand), Pacific Air Forces (5 awards, $104 thousand), and Defense Logistics Agency Aviation (5 awards, $2 thousand). By potential value, the Engineer Research and Development Center dominates with $533 thousand across 7 awards, followed by the Army Corps of Engineers Engineering District Fort Worth ($231 thousand, 2 awards) and FORSCOM ($153 thousand, 3 awards). Humboldt holds one minor subcontract position as a supplier to Atlantic Diving Supply, Inc. on a high-pressure controller component sub-award (January 2024). Combined potential value across all 110 awards totals $2.4 million, with $2.6 million obligated to date. Only two awards complete within the next twenty-four months (combined potential value $213 thousand).
