Dredge Constructors LLC

Dredge Constructors LLC, a woman-owned small disadvantaged business based in Sebastopol, California, manufactures and supplies specialized dredging equipment and replacement parts to the U.S. Army Corps of Engineers as a prime contractor under total small business and full-and-open set-asides. The company operates as a for-profit limited liability corporation self-certified as both a woman-owned small business and small disadvantaged business, competing across ship-building, pump manufacturing, and construction equipment categories (primary NAICS: 333914 and 336611, top PSC: G030 Miscellaneous Ship and Marine Equipment).

Dredge Constructors maintains a single-customer footprint. All twenty recent prime awards and 100% of combined potential value flow from the Department of the Army Corps of Engineers, with thirteen awards valued at $5.7 million routed through the Corps' national office and six awards ($1.3 million combined) distributed across Engineering Districts in St. Louis, St. Paul, and Philadelphia. The company has served the St. Paul District since 2016 and holds standing as a key supplier to the Corps' fleet of inland navigation dredges.

The company's capability portfolio centers on manufacturing booster pumps, hydraulic suction dredge cutterheads, pump shells, impellers, propellers, and replacement components for Corps dredging vessels. Recent representative work includes a $3.4 million definitive contract awarded July 2024 to design, manufacture, and deliver a 20-inch diesel-powered booster pump for the Dredge Goetz, capable of delivering 15,850 to 19,000 gallons per minute at pressures from 80 to 150 PSI; a $502,750 purchase order for spare parts (impellers, suction liners, hub liners, pump shells) compatible with the Vosta LMG HDP 550 hydraulic pump on the same vessel; and a $277,953 definitive contract for FY23 Vosta VL900 dredge pump parts. Older awards include a $99,880 purchase order for Dredge Jadwin propellers and a $65,210 order for a hydraulic suction dredge cutterhead with five sets of spare cutting edges.

Activity has remained modest but consistent — three awards in 2021 declining to two in 2022, recovering to four in 2024, with one award in early 2026. The recompete cliff shows minimal near-term pressure: only one award ($88,000) reaches ultimate completion within the next twenty-four months. Combined obligated dollars equal combined potential value across the portfolio ($7 million), indicating firm fixed pricing and minimal change order risk. The vendor has no subcontract footprint in the source data and operates entirely as a prime supplier, with no diversification outside the Corps of Engineers customer base.
