About the company
Seacoast Construction Inc., doing business as Seacoast Marine Construction, is a small disadvantaged business providing hydraulic and mechanical dredging, channel maintenance, and coastal ecosystem restoration services to the U.S. Army Corps of Engineers and the Department of the Army under total small business set-asides. Based in West Sayville, New York, the firm operates as a for-profit Subchapter S corporation and competes exclusively under small business set-asides across its federal footprint.
Seacoast's three recent prime contracts span maintenance dredging and coastal restoration work. The largest is a $42.984 million firm-fixed-price definitive contract awarded by the U.S. Army Corps of Engineers, Baltimore District, on August 12, 2024, for Mid-Chesapeake Bay Barren Island Restoration Phase 2, extending through October 3, 2027. This work encompasses construction of two bird islands, removal and placement of foundation materials, construction and modification of stone sill structures, installation of geotextile structures, spillway design and installation, and dredging of material from the Honga & Tar Bay Federal Navigation Channel, with performance at Fishing Creek, Maryland. Seacoast also holds a $4.169 million definitive contract from the Department of the Army, awarded May 25, 2026, for maintenance dredging of Absecon Inlet (Clam Creek) near Brigantine, New Jersey, involving hydraulic pipeline dredging of approximately 100,000 cubic yards of shoaling material with beneficial use placement at Boot Island and completion by February 19, 2027. A third contract, valued at $2.167 million and awarded August 15, 2024, covers maintenance dredging of Mattituck Harbor's federal navigation channel in New York using mechanical dredging with clamshell bucket equipment and upland disposal of approximately 11,500 cubic yards of silt and clay.
Customer concentration is tight: the Army Corps of Engineers (including its Baltimore District) and the Department of the Army account for 100% of awards and combined potential value of $49.3 million. All dollars obligated match combined potential value, indicating full funding across the three awards. Two of these three contracts — totaling $47.2 million — face ultimate completion within the next twenty-four months and represent significant recompete exposure in 2027. Seacoast operates exclusively as a prime contractor; the source carries no subcontract work.
