About the company
DDC 4C, LLC, a tribally-owned, Native American-operated 8(a)-certified small business based in Scottsdale, Arizona, operates as a prime contractor delivering environmental consulting, rangeland monitoring, archaeological assessment, natural resource management, and infrastructure services to civilian federal agencies. The company is a child entity of Dine Development Corporation, a federally recognized Indian Tribe, and holds SBA 8(a) Program certification valid through July 8, 2033, along with designations as an Indian Economic Enterprise, Indian Small Business Economic Enterprise, and self-certified small disadvantaged business. DDC 4C competes predominantly under Indian Small Business Economic Enterprise and Total Small Business set-asides, with occasional full-and-open awards; all 25 recent awards in the source are prime contracts with no subcontractor footprint.
Customer concentration is heavily tilted toward Interior Department bureaus and environmental agencies. The top five funding agencies account for 68% of award volume: the Bureau of Indian Affairs Navajo Region dominates by count (9 awards, $3.1 million combined potential value), but NASA's Shared Services Center anchors the potential-value hierarchy with 2 awards carrying $259.3 million in combined potential value. This split reflects DDC 4C's dual-track portfolio — numerous small environmental projects for BIA and Fish and Wildlife Service alongside large enterprise vehicles for NASA and Forest Service. EPA Region 7, the Indian Health Service, the Army Corps of Engineers, and the Bureau of Reclamation round out the active set. The source notes 13 distinct customer agencies served across 25 awards with a combined potential value of $330.8 million, though only $13 million has been obligated to date (4% of potential value), indicating most awards are IDVCs or BPAs early in their task-order lifecycle.
DDC 4C holds four major parent vehicles anchoring its federal footprint. The NASA Environmental Support Services (NESS) BPA, awarded May 1, 2025, carries a $225 million ceiling through April 30, 2035 and operates as an enterprise vehicle providing environmental compliance, natural resource management, habitat restoration, and facility maintenance services across NASA locations and subordinate federal agencies. A $50 million USDA Forest Service Blanket Purchase Agreement for the Land Management Integrated Resources (LMIR) program, awarded September 17, 2026, covers professional services, natural resources restoration, engineering, project management, revegetation, and road work nationwide. A GSA Federal Supply Schedule contract (CAGE 47QRAA24D006X), awarded April 23, 2024, carries a $1.5 million ceiling through April 22, 2029 and has generated six task orders (combined potential value $264.3 million) across Army Corps of Engineers, Bureau of Reclamation, and regional Interior clients. An EPA Region 7 single-award IDIC valued at $3.788 million (October 17, 2025, through November 2, 2027) supports historic resource background studies and phase surveys at Superfund sites in Kansas, Nebraska, Oklahoma, and Missouri.
Recent concrete work exemplifies the capability breadth. Four September 2026 awards from BIA Navajo Region — valued at $421,000 to $598,000 each — call for vegetation surveys and rangeland inventories across 450,000–850,000 acres in Arizona and New Mexico using double-sampling methodology, GIS analysis in ArcGIS Pro, and deliverables including technical reports and geospatial datasets. A $676,000 August 2026 contract with Fish and Wildlife Service Region 4 specifies fuel-break mastication on amphibious pontoon excavators at Pocosin Lakes National Wildlife Refuge in North Carolina, requiring specialized low-ground-pressure equipment for sensitive peat soils. A September 2026 BIA Southern Plains Region archaeological survey worth $435,000 covers 1,907 acres across Oklahoma counties with pedestrian survey, shovel testing, and ARPA permitting under Secretary of Interior professional qualification standards. A $3.3 million August 2024 Army Corps of Engineers delivery order under the GSA Schedule covers Best Management Practices maintenance and related services at Fort Liberty, North Carolina, through September 2026. The $34.3 million August 1, 2026 NASA task order represents the largest single award and reflects DDC 4C's positioning on the NESS enterprise BPA.
Activity has held steady across 2024–2026, averaging approximately 8.3 awards per year (2024: 8 | 2025: 8 | 2026: 9), with the most recent award dated September 24, 2026. Ten awards totaling $3.9 million in combined potential value reach ultimate completion within the next twenty-four months, representing a modest recompete window concentrated in small BIA rangeland and archaeological work. The GSA Schedule labor portfolio spans 23 categories priced from $59.81 per hour (administrative and clerical) to $217.95 per hour (subject matter expert with 15 years' experience), with mid-career archaeologists and GIS specialists in the $73–$119 range; all positions require high school to bachelor's education, and no security-cleared labor is offered. Service Contract Inventory data show $1.9 million in FY2025 invoiced prime revenue delivered at a flat $437.79 per hour across the SCI-reportable contracts, with approximately 33% of hours performed by subcontractors on those reportable engagements, though the corporate structure carries no named subcontractor footprint in the recent award history.
