DDC-4C Contracting Advantages

As a tribally-owned 8(a) certified firm, DDC-4C offers unique advantages in federal contracting. These include:

  • No dollar threshold on 8(a) sole-source/direct awards [13 CFR 124.506 (b)]. The government can award sole-source contracts up to $22M in value without justification and approval (J&A), and awards over $22M with J&A.
  • Lower Overhead and General and Administrative (G&A) costs. We can leverage the resources of our parent company, which results in more efficient operations and greater cost savings for our customers.
  • 8(a) awards to tribal-owned firms cannot be protested [13 CFR  124.517(a)]. Contract awards made to tribal-owned companies are not subject to protest.
  • Department of Defense Indian Incentive Program (IIP). This congressional-sponsored program provides a 5% rebate to federal prime contractors and subcontractors that subcontract to Indian-owned organizations.
