About Orion Marine Construction, Inc.
Orion Marine Construction, Inc., doing business as Misener Marine Construction, is a Tampa, Florida–based marine dredging contractor that performs pipeline cutterhead and maintenance dredging for the U.S. Army Corps of Engineers as a prime contractor on unrestricted, full-and-open procurements—98% of its recent federal awards are primes, with no set-aside designations characteristic across the portfolio.
Orion's customer base is heavily concentrated within the Army Corps of Engineers ecosystem. The top five funding agencies account for 80% of awards by count and 93% by combined potential value, dominated by the Department of the Army Corps of Engineers broadly (23 awards, $712.7 million combined potential value), the Engineering District Jacksonville (6 awards, $517.7 million), the Engineering District Fort Worth (11 awards, $97.7 million), the Engineering District Galveston (7 awards, $72 million), and the Department of the Army (4 awards, $156.4 million). This concentration reflects Orion's specialization: of 60 awards, 60 fall under NAICS 237990 (Other Heavy and Civil Engineering Construction), with service-delivery codes clustered around canal maintenance (16 awards), dredging facility construction (11 awards), and dredging facility maintenance and repair (21 awards combined). Recent representative work includes a $86.3 million firm fixed-price definitive contract awarded December 17, 2025, by the Army Corps of Engineers Galveston District for maintenance dredging at the Mouth of Colorado River, Texas, with beneficial use placement at Sargent Beach (completion October 21, 2027); a $40.3 million definitive contract awarded April 2, 2026, by the Department of the Army for maintenance dredging of the Matagorda Ship Channel in Texas (completion November 26, 2026); and a $29.3 million firm fixed-price contract awarded October 5, 2024, by the Galveston District for Corpus Christi Ship Channel maintenance dredging covering approximately 2.5 million cubic yards (completion October 10, 2025).
Orion holds a $40 million single-award indefinite delivery indefinite quantity contract with the Army Corps of Engineers New Orleans District for on-call cutterhead dredging services across the Atchafalaya Basin, Gulf Intracoastal Waterway, and miscellaneous projects (ultimate completion August 2, 2025), with two delivery orders issued to date. Award activity has remained relatively stable at four to five awards per year from 2022 through 2025, with two awards in 2026 to date. Three awards (combined potential value $134.7 million) reach ultimate completion within the next twenty-four months, creating near-term recompete exposure. Orion operates as a subsidiary of Orion Construction, LLC, a Houston, Texas–based parent entity. The vendor subcontracts as a mechanical dredging and demobilization specialist to The Dutra Group on a Tampa Harbor maintenance dredging project (awarded July 14, 2025). Combined potential value across the 64-award portfolio totals $1.67 billion, with $612 million obligated to date (37% utilization).
