About the company
Underwater Engineering Services Inc., a Fort Pierce, Florida-based subsidiary of Greenman-Pedersen Inc., provides commercial diving, marine construction, inspection, repair, and specialized underwater engineering services to federal agencies as a prime contractor (96% of recent awards), competing full-and-open without set-asides. The vendor's federal work centers on manatee protection system operations, maintenance, and repair services for the U.S. Army Corps of Engineers Jacksonville District, complemented by diving operations for the U.S. Coast Guard and marine engineering support across eight customer agencies.
Customer concentration is extreme: the Army Corps of Engineers Jacksonville District accounts for 15 awards and $15.8 million of the vendor's combined potential value — approximately 91% of the $17.3 million total across 27 prime awards. The Coast Guard has placed three small purchase orders (combined $17 thousand) for diving services at Fort Pierce, the National Park Service Southeast Region has two awards ($297 thousand), and the Department of Commerce National Institute of Standards and Technology holds one $522 thousand award. The vendor's most recent and largest prime contract is a $5.225 million firm-fixed-price definitive contract awarded March 6, 2026, by the Army Corps of Engineers Jacksonville District for Manatee Protection Systems operations and maintenance services at six lock and dam facilities in Florida, running through March 5, 2031. Earlier representative work includes a $707 thousand definitive contract (September 2024, completed August 2025) and a $184 thousand purchase order (December 2021) for MPS repair and replacement with the Army Corps of Engineers.
Activity is sparse and episodic. The vendor has received two awards in 2025 and two in 2026, compared to one in 2024 and one in 2021, with a median cycle of one to two awards per year across the past five years. The vendor holds seats on an Army Corps of Engineers indefinite delivery contract (W912EP06D0009, four task orders, $4.6 million combined potential value). Recompete exposure in the next twenty-four months is minimal — one award ($522 thousand) reaches ultimate completion inside that window. The vendor is structured as a child entity of Greenman-Pedersen Inc., a Subchapter S corporation consulting engineering firm; Service Contract Inventory data shows minimal SCI-reportable activity (one sub record, FY2022, zero FTEs on prime contracts). The vendor operates as a specialized contractor with narrow customer and capability concentration, dependent on Jacksonville District Corps work for portfolio sustainability.
