About the company
DDC Construction Services LLC, doing business as DDC 4C, is a Navajo Nation-owned, tribally-owned 8(a) certified small disadvantaged business that delivers environmental consulting, forestry management, habitat restoration, and land management services to the Department of Defense and civilian agencies as a prime contractor (100% of recent awards). The company is a subsidiary of Dine Development Corporation, headquartered in Scottsdale, Arizona, and competes predominantly under 8(a) and Total Small Business set-asides on federal environmental and forestry programs.
DDC 4C's capability footprint is concentrated in endangered species habitat management, prescribed fire operations, mechanical fuel reduction, wetland delineation, cultural resources surveys, and forestry support services for military installations and federal lands. Representative prime work includes a $28.1 million single-award Indefinite Delivery Contract with the U.S. Marine Corps (awarded November 1, 2022, through November 3, 2027) for site preparation, longleaf pine seedling planting, red-cockaded woodpecker habitat improvement, wildlife management, and aquatic weed control across up to 2,000 acres annually at Camp Lejeune and Marine Corps Air Station–New River, North Carolina; a $7.5 million Army Corps of Engineers environmental support services IDC (August 1, 2021, through July 31, 2026) covering National Environmental Policy Act document preparation, biological assessments, protected species surveys, wetland delineation, and cultural resource management in North Carolina; a $6.5 million Blanket Purchase Agreement with the Forest Service Southern Region for reforestation and invasive species management; and a $4.12 million 8(a) Sole Source contract with Department of Defense headquarters (awarded September 30, 2022, through September 29, 2027) for implementation and yearly maintenance of Sikes Act Permit Sales and Recreation Management Services (SAPRMS), with Applied Sciences and Information Systems Inc. (Asis) as a major subcontractor providing recreation management software. Recent competitive and sole-source 8(a) task orders span red-cockaded woodpecker habitat restoration ($428 thousand, Department of the Army, September 2025), understory mastication across 400 acres ($390 thousand, Department of the Army, September 2025), prescribed fire operations for wildfire hazard mitigation across 2,130 acres ($225 thousand, Department of the Army, June 2026), and cultural resources surveys with wetland delineation ($190 thousand, Department of the Army, June 2024).
Customer concentration is dominated by Department of Defense field commands. The U.S. Marine Corps leads by award count (27 awards, $30 million combined potential value), followed by the Department of the Army (20 awards, $4.4 million), the Army Corps of Engineers Engineering District Wilmington (18 awards, $3.7 million), and the Forest Service Southern Region (4 awards, $6.6 million), together accounting for 78% of recent awards. A single GSA Federal Acquisition Service vehicle carries a $50 billion placeholder ceiling representing DDC 4C's participation in the 8(a) STARS III Government-Wide Acquisition Contract for IT services, though that vehicle has not generated measurable task-order activity in the source data. The top three primary indefinite delivery vehicles by task-order volume are the Marine Corps forestry IDC (34 task orders, $6.6 million), the Army Corps of Engineers environmental support IDC (18 task orders, $3.7 million), and a Forest Service BPA (3 task orders, $122 thousand).
Activity has remained relatively flat year over year at roughly 10–16 awards per year from 2022 through 2025, declining to six awards in the first seven months of 2026. Nine awards (combined potential value $5.3 million) face ultimate completion within the next twenty-four months and represent recompete exposure, primarily Camp Lejeune herbicide, habitat, and wildlife management task orders due to complete by year-end 2026 and early 2027.
DDC 4C does not appear as a subcontractor in the source data and operates exclusively as a prime contractor. The company does place subcontractors on its own work — Asis is named as a major sub on the SAPRMS recreation management contract — but the source provides limited visibility into routine sub-team composition across the broader environmental forestry and consulting portfolio. SCI-reported invoiced activity is minimal: the dataset captures $39 thousand in a single FY2022 record with no measurable FTE data, indicating that most DDC 4C work either falls below the $150,000 SCI reporting threshold, is classified, or is reported through customer agencies' own SCI filings. The median government-paid rate on the single reported SCI record ran $1,159.52 per hour, reflecting high-skill professional and technical labor, though this single data point provides limited insight into company-wide rate posture.
NAICS concentration runs to Environmental Consulting Services (44 awards) and Support Activities for Forestry (32 awards), with PSC coding dominated by Other Environmental Services (42 awards) and Natural Resources/Conservation–Land Treatment Practices (25 awards). DDC 4C's strategic positioning anchors to the Marine Corps' Camp Lejeune and MCAS–New River forestry and habitat mission in coastal North Carolina, where the company has held a single-award IDC since 2022 and issues dozens of task orders annually for threatened-species protection and land stewardship. The company's 8(a) certification and tribal ownership provide recurring access to set-aside vehicles; participation in 8(a) STARS III positions it for potential IT-services expansion beyond its current environmental and forestry core.
