About the company
Ahtna Marine & Construction Company, LLC, operating as Cavache Dredging, is an Alaska Native Corporation-owned, SBA 8(a)-certified small disadvantaged business based in Boynton Beach, Florida, that delivers waterway maintenance dredging, harbor and inlet dredging, ecosystem restoration, and military facility repair and construction services to federal customers as a prime contractor exclusively. The company competes under 8(a) set-asides (both sole-source and competitive) and total small business set-asides across its footprint, with occasional full-and-open designations on specialized ecosystem restoration work.
Ahtna's customer concentration is heavily skewed toward the Army Corps of Engineers. The top five customer agencies account for 94% of recent awards by count; the Department of the Army Corps of Engineers Engineering District Jacksonville alone represents 8 awards with $423.7 million in combined potential value — roughly 88% of the vendor's total $483.2 million in combined potential across all awards. The remaining concentration splits among the Army Corps of Engineers Engineering District Charleston ($16 million), the broader Army Corps of Engineers ($15.6 million), the Army Corps of Engineers Finance ($13.8 million for ecosystem restoration), and the Defense Logistics Agency Energy ($12.6 million for fuel facility repair at Alaskan Air Force bases). This stark dominance by a single district office creates significant recompete and customer-concentration risk: three awards with $15.7 million combined potential value reach completion inside the next twenty-four months.
Ahtna holds a single-award indefinite delivery contract with the Army Corps of Engineers Jacksonville District, awarded July 17, 2025, with a $400 million ceiling and ultimate completion July 16, 2030. The contract authorizes task orders ranging from $1 million to $25 million for maintenance dredging of waterways, harbors, and channels within South Atlantic Division boundaries; two task orders have been placed to date. Primary capability framing spans NAICS 237990 (Other Heavy and Civil Engineering Construction), with representative work including a $13.8 million Lake Worth Lagoon Ecosystem Restoration Project contract (December 2023) for bird nesting habitat under the Continuing Authorities Program Section 1135, a $10.1 million Atlantic Intracoastal Waterway breach inlet dredging contract (March 2024) with placement at Charleston beaches, and a $7.8 million John Martin reservoir dredging contract in Colorado (June 2023) performed under the Ahtna-J.F. Brennan Joint Venture. Recent work also includes $5 million and $7.6 million 8(a) sole-source fuel facility repair contracts at Eielson Air Force Base and Eareckson Air Station, Alaska (September 2024), and a $1.4 million Air National Guard roof repair award at Great Falls, Montana (October 2024).
Ahtna Marine & Construction Company is a subsidiary of Ahtna Federal Holdings, LLC, also Alaska Native Corporation-owned and SBA-certified as 8(a) and small disadvantaged. The corporate structure includes joint venture entities with J.F. Brennan — the Ahtna-J.F. Brennan JV, Ahtna-Brennan JV LLC, and Ahtna Marine-Brennan JV LLC — that appear on contracts where heavy dredging equipment or extended performance timelines require partnering. Activity has been volatile year to year (one award in 2022, five in 2023, five in 2024, three in 2025, one in 2026 as of mid-June), reflecting lumpiness in Corps of Engineers dredging procurement cycles rather than systematic growth. With $83.2 million obligated against a $483.2 million combined potential (17% obligation rate), the pipeline carries substantial unexercised value, though $400 million of that sits in the newly awarded Jacksonville District IDIQ, which has not yet matured into a large task-order flow.
