Onaka Gumi has established itself as a primary contractor for the U.S. Department of Defense, competing successfully in open competition across multiple federal agencies without relying on socioeconomic set-asides, demonstrating its capacity to deliver complex infrastructure and logistics solutions at competitive market rates.

Onaka Gumi has demonstrated extensive federal contracting experience through hundreds of prime contract awards spanning construction, infrastructure repair, demolition, hazardous materials management, and waste disposal services. The company's past contract awards include major definitive contracts from Pacific Air Forces valued at $7.7 million and $4.5 million for concrete and steel repair work addressing environmental deterioration at military facilities, as well as smaller definitive contracts for specialized projects such as floor drain spalling repairs ($373,973) and bleacher shelter construction ($607,278) for the Marine Corps. The contractor has provided substantial environmental remediation and waste management services through numerous delivery orders from the Defense Logistics Agency Disposition Services, handling industrial waste disposal, alkaline waste, flammable materials, non-regulated liquids, compressed gas cylinders, paint materials, and sludge removal, with individual task orders ranging from thousands to over $119,000. Onaka Gumi has also executed significant infrastructure repair projects including barracks renovation at White Beach ($3.87 million), demolition of multiple facilities at White Beach ($785,746), Halsey Road repair ($1.94 million), and perimeter road repair and erosion control at Camp Gonsalves ($8.04 million), all under Navy and Marine Corps delivery orders. The company's work encompasses design-build and design-bid-build construction services, erosion control and sediment mitigation work, bridge repair and replacement, blast door replacement at munitions storage facilities, and hazardous materials abatement including asbestos removal. All awards were made through open competition with no set-aside designations, with primary funding from the U.S. Department of the Navy, Pacific Air Forces, Defense Logistics Agency Disposition Services, U.S. Army Corps of Engineers, and U.S. Marine Corps, demonstrating the breadth of its federal customer base.
