Callan Marine LIMITED

Callan Marine LIMITED (Callan Marine, LTD. Division), a Texas-based dredging and coastal restoration contractor operating as a partnership or limited liability partnership, delivers pipeline dredging, hopper dredging, channel deepening, and beach nourishment services to the Department of the Army and U.S. Army Corps of Engineers as a prime contractor on all but one recent award. The vendor competes on unrestricted, full-and-open procurements without set-aside designation across its footprint.

Callan Marine's capability portfolio centers on heavy marine construction for federal waterway maintenance and coastal protection along the Gulf Coast and Atlantic seaboard. Recent prime awards include a $109.2 million firm fixed-price definitive contract from the Army for dredging and channel deepening of Brazos Island Harbor Phase II in Cameron County, Texas (ultimate completion June 4, 2026), with 35.6% subcontracting goals established for small businesses; a $111.8 million pipeline dredging contract for the Corpus Christi Ship Channel Upper Harbor Reach in Nueces and San Patricio Counties, Texas (ultimate completion March 19, 2026); a $47.25 million dune and beach sand fill contract from USACE for Post-Ida coastal restoration in Grand Isle, Louisiana (ultimate completion April 9, 2025); and a $33 million pipeline dredging contract from USACE for the Gulf Intracoastal Waterway Texas West Galveston Bay Barrier Island Reconstruction Project (ultimate completion June 27, 2025). More recent 2024–2025 awards include a $23.6 million maintenance dredging contract for Port Mansfield, Texas (ultimate completion January 31, 2027, with $4,200 per day liquidated damages for schedule delays) and a $6.8 million Gulf Intracoastal Waterway maintenance dredging contract in Galveston and Chambers Counties, Texas.

Customer concentration sits entirely within the Department of the Army ecosystem. The Department of the Army Corps of Engineers (10 awards, $297 million combined potential value) and the Army proper (4 awards, $251.5 million) account for most volume and dollars, supplemented by the USACE Engineering District Jacksonville (2 awards, $450 million combined potential value) and the Department of the Interior Fish and Wildlife Service (1 award, $53.7 million). The awards span multiple USACE districts (Galveston, Jacksonville) and reflect operational concentration in Texas coastal waters and Gulf waterway systems. USACE holds a published $45 million Indefinite Delivery/Indefinite Quantity contract with Callan Marine for rapid-response pipeline dredging services through the Galveston District, positioning the vendor as a standing resource for emergency or time-sensitive dredging tasking.

Callan Marine's recent activity shows concentration in 2023–2024 (four awards in 2023, three in 2024) with a single 2025 award. One award carrying $23.6 million in combined potential value faces ultimate completion in the next twenty-four months, creating immediate recompete exposure on the Port Mansfield maintenance dredging contract. The vendor maintains a sub footprint of one listed sub-award: dredging and placement of dredge material on the Houston Ship Channel Improvement Project Segment 3 as a subcontractor to McCarthy Building Companies, Inc. (awarded September 20, 2024). The portfolio reflects NAICS coding across Other Heavy and Civil Engineering Construction, with primary PSC concentration in maintenance of canals (5 awards), construction of dredging facilities (3 awards), and maintenance of dredging facilities (3 awards). Combined potential value across all eighteen awards totals $1.05 billion, with $490 million obligated to date.
