Maritime & Construction Management Inc.

Maritime & Construction Management Inc., a minority-owned community development corporation headquartered in Sasebo, Nagasaki, Japan, provides ship maintenance and repair services to the U.S. Navy as a prime contractor on a full-and-open basis, with no set-aside designations across its recent federal work.

The vendor's customer footprint is singularly concentrated: the Department of the Navy's Military Sealift Command accounts for 18 of 25 awards (100% coverage by award count and by potential value) and $469 thousand of the $491 thousand combined potential value. Naval Sea Systems Command and United States Pacific Fleet Forces round out the three distinct Navy customer offices served. Work is performed in Japan, reflecting the vendor's geographic position as a regional maintenance provider for forward-deployed U.S. Navy assets. Representative recent awards include a $19,741.89 firm fixed-price purchase order awarded February 26, 2026, by Military Sealift Command for urgent ship maintenance aboard the USNS Alan Shepard — replacement of 30-inch butterfly high sea chest strainer isolation valves, machining of HTFW No. 3 pump couplings, and inspection and re-gasketing of lube oil cooler plates, with ultimate completion required by March 8, 2026. A November 2023 purchase order from Military Sealift Command for a YUK MOV valve carried a $6,736.00 ceiling value. Earlier work included June 2022 and May 2022 purchase orders for T-AO 200 port main engine exhaust stanch and engine exhaust leak repair, valued at $20,766.40 and $14,064.00 respectively.

Activity is sporadic — one award in 2021, two in 2022, two in 2023, and one in 2026 — suggesting task-order or purchase-order responsiveness rather than sustained prime incumbency. All 25 awards across the source's five-year window are prime contracts, all obligated at their ceiling values, totaling $491 thousand. The vendor's capability portfolio centers on ship building and repairing (17 awards under NAICS 336611), with secondary work in marine equipment maintenance and repair and engine/turbine component work. The vendor operates as a sole source of supply or as a regional provider for emergency and urgent maintenance rather than as a multi-award vehicle participant or scheduled supplier on government-wide agreements.
