About CS Marine Constructors Inc.
CS Marine Constructors Inc., a Vallejo, California–based subsidiary of Sealaska Commercial Services LLC, provides maritime infrastructure construction, repair, and floating crane services to federal agencies as a prime contractor operating exclusively under small business set-asides. The company is SBA 8(a) certified through July 22, 2030, and carries multiple federal small disadvantaged business designations including Alaskan Native Corporation Owned, Indian Economic Enterprise, and Minority Owned status. CS Marine competes 100% as a prime (137 awards across the source data with zero subcontract work) and holds a $500,000 blanket purchase agreement with the U.S. Maritime Administration for floating crane services at Suisun Bay Reserve Fleet in Benicia, California, with individual call orders capped at $38,000.
CS Marine's customer concentration tilts sharply toward the U.S. Coast Guard, which accounts for 84 of 137 awards (71% coverage) with $2.2 million in combined potential value. The Department of Transportation Maritime Administration represents the second-largest customer (2 awards, $545 thousand), followed by the Department of the Interior National Park Service, the Department of the Navy, and the Department of the Army. The NAICS profile reflects maritime and civil construction work: 29 awards fall under Other Heavy and Civil Engineering Construction, with additional awards in specialty trade contracting and mining services. Recent concrete work includes a $99,890 firm-fixed-price purchase order from the National Park Service (April 2026) for removal and disposal of a 109-foot floating dock at Hyde Street Pier in San Francisco Maritime National Historical Park, with off-site recycling and transport by barge; a $44,940 BPA call order from Maritime Administration (September 2025) for crane services lifting a 30,000-pound NAVMOOR anchor at Suisun Bay Reserve Fleet; and a $113,320 definitive contract from the National Park Service Pacific West Region (September 2022) for moorings replacement in San Francisco. The company maintains $5 million in protection and indemnity maritime coverage and operates the BPA with daylight-hours service windows (Monday through Friday, excluding federal holidays) focused on anchor retrieval and precision lifting operations.
Recent activity remains sparse: one award in 2022, two in 2025, and one in 2026. The source records $6.7 million in combined potential value against $11.2 million in actual obligated dollars across 137 awards, a signal of heavy prior obligations on Coast Guard IDCs. CS Marine places task orders against three primary Coast Guard indefinite delivery contracts (DTCG8800D623086 with 30 task orders, HSCG8806D660000 with 15 task orders, and HSCG8811DPQQ017 with 3 task orders) and a single Maritime Administration BPA for crane services. Service Contract Inventory data is minimal—one FY2024 SCI record showing 0.4 FTEs as a named subcontractor—reflecting the company's goods-and-construction orientation rather than federal service contracting above the $150,000 SCI threshold.
