The NDN Companies

The NDN Companies, a Jacksonville, Florida-based SBA 8(a)-certified minority-owned and women-owned small business, delivers environmental remediation, cultural resource management, archaeological surveys, and facility support services to federal agencies as a prime contractor (97% of recent awards) and subcontractor. The firm holds Subchapter S corporate status and carries self-certified small disadvantaged business and economically disadvantaged women-owned small business designations, with 8(a) certification valid through October 2028. The company operates through three named subsidiaries: NDN Otie JV LLC (minority and women-owned joint venture), The NDN Sundance JV LLC, and Ndn-Sundance JV Alliance LLC.

The NDN Companies' customer base concentrates heavily within the Army Corps of Engineers family. The top five funding entities account for 55% of recent awards by count and 75% by combined potential value, led by the Department of the Army Corps of Engineers broadly (13 awards, $17.3 million combined potential value), the Corps' Omaha District (7 awards, $10.3 million), the Corps' Mobile District (4 awards, $10.5 million), the Air Force Civil Engineer Center (8 awards, $4.3 million), and the Corps' Albuquerque District (3 awards, $3.8 million). The Department of Transportation Immediate Office of the Secretary ranks sixth by count (8 awards, $1.3 million) but is material for FAA facility remediation and demolition work. Beyond these anchors, the vendor works with 21 additional federal agencies spanning the Environmental Protection Agency, Defense Logistics Agency, National Park Service, NOAA, Bureau of Reclamation, and the Forest Service, reflecting a diversified but Army Corps-anchored footprint.

Recent representative prime awards span environmental remediation, demolition, cultural resource surveys, and facility support. NDN secured a $5.77 million 8(a) sole-source definitive contract from the Defense Enterprise Information Systems Mobile (February 2026) for Harrison County beach dune planting in Gulfport, Mississippi through August 2027. A $3.7 million modification exercised Option Year 1 of an administrative support services contract with the Army Corps of Engineers Albuquerque District at Fort Wingate, New Mexico (awarded December 2024, ultimate completion December 2025). The vendor completed two FAA facility demolition and remediation purchase orders under the Immediate Office of the Secretary: a $213,529 Total Small Business set-aside (May 2026) for demolition at MKL and BWG facilities in Tennessee and Kentucky, and a $105,433 Total Small Business set-aside (June 2026) for lead-contaminated soil excavation and disposal at Savannah Outer Marker and QYL Remote Transmitter facilities in Georgia. The Army Corps of Engineers Omaha District awarded a $719,447 delivery order (February 2024) for Thunder Butte and Lower Moreau studies. Environmental remediation and cultural resource work dominates the portfolio: 36 awards fall under NAICS Environmental Consulting Services, 11 under Remediation Services, and 8 under Other Heavy and Civil Engineering Construction; by PSC, 35 awards map to Other Environmental Services and 7 to Repair or Alteration of Dredging Facilities.

The NDN Companies holds a substantial indefinite delivery vehicle portfolio anchoring its task-order footprint. The Army Corps of Engineers Omaha District awarded a $4.5 million 8(a) sole-source single-award IDC (August 2022, extended through February 2028) for environmental, cultural resource management, facility support, and wildland fire management services at Army and Air Force installations; ten task orders totaling $4.9 million have been issued against this vehicle, including $719,447 for Thunder Butte studies, $561,253 for Buckley Space Force Base environmental and facility support, $450,743 for Iowa Army Ammunition Plant cultural support, and $492,810 for wildland fire management planning across eight Texas Air Force installations. The Army Corps of Engineers Tulsa District awarded a $6.5 million multiple-award IDIQ (September 2024 through August 2029) for cultural resource services; three task orders totaling $245,070 have been issued for Broken Bow Cultural Resource Survey ($130,818), Old Willis Cemetery archaeological fieldwork ($114,251), and minimum guarantee. The Army Corps of Engineers Mobile District holds a $4.5 million single-award IDC (September 2025 through September 2028) for Basewide Environmental Sustainment Support (BEST) encompassing Installation Restoration, Defense Environmental Restoration Program sustainment, and Restoration and Modernization support; two delivery orders totaling $260,690 have been issued for San Juan Bay Estuary benthic habitat survey ($258,190) and minimum guarantee. The Army Corps of Engineers Los Angeles District awarded a $2 million 8(a) sole-source single-award IDC (August 2024 through August 2029) for environmental remediation services. The vendor also holds a Defense Logistics Agency Disposition Services single-award 8(a) IDC ceiling $112,997 (May 2025 through May 2030) with one $14,555 delivery order issued, and a General Services Administration Federal Supply Schedule contract ceiling $1 million (May 2024 through May 2029) under Special Item Number 541620 for environmental consulting services. A U.S. Forest Service Region 8 Blanket Purchase Agreement ceiling $1 million (June 2023 through December 2025) covers archaeological support survey services in Florida national forests.

The GSA Schedule labor portfolio comprises 12 categories with hourly rates spanning $52.32 (clerical, bachelor's degree, one year experience) to $174.58 (senior project manager, bachelor's degree, ten years experience). Mid-tier positions include cultural resource specialist at $112.68 per hour, project manager I at $137.06, and site health and safety officer at $108.74. All positions require bachelor's-level education; no security-cleared roles are offered. Service categories include NEPA compliance, cultural resource assessments, Native American coordination, environmental compliance and site assessments, remediation services, wildland fire consulting, and industrial hygiene support, with worldwide place of performance spanning CONUS and OCONUS.

Recent activity shows steady engagement across 2022 through 2026, with 7 awards in 2022, 11 in 2023, 14 in 2024, 12 in 2025, and 8 recorded through June 2026. Eleven awards (combined potential value $9 million) face ultimate completion within the next twenty-four months and represent recompete exposure. Combined potential value across all 73 awards totals $62.1 million, with $30.9 million obligated (50% draw rate). The vendor subcontracts minimally — only 2 of 73 awards (3%) are sub positions — working under Mn-Bmcd SE JV as prime on environmental support and feasibility study data gathering at Naval Air Station Jacksonville's Mulberry Marina (August 2025), and under The Haskell Company on a gopher tortoise survey relating to a differing site condition at a data pathway installation (September 2024). The NDN Companies' set-aside footprint tilts toward 8(a) sole-source and total small business designations; full-and-open awards appear predominantly through Corps of Engineers IDIQ task orders and GSA Schedule ordering.
