Benefits for Federal Agencies Using GWACs

How Task Order Competition Works on GWACs

  1. 1
    Agency identifies IT requirement

    The requiring agency works with their contracting office to define the scope, develop a performance work statement or statement of work, establish evaluation criteria, and determine the appropriate task order type. Requirements must fall within the GWAC scope and IT definition.

  2. 2
    Fair opportunity notice issued

    The GWAC holder receives notification of the task order competition through the contract vehicle's ordering portal. The agency must provide fair opportunity to all GWAC holders unless an exception applies, such as sole source justification for orders under certain thresholds.

  3. 3
    Contractors submit proposals

    GWAC holders interested in the work prepare and submit proposals according to the instructions provided. Task order proposals are typically shorter than full competition proposals but must still demonstrate technical capability and provide pricing.

  4. 4
    Agency evaluates and selects

    The agency evaluates proposals against stated criteria and selects the contractor offering the best value. Evaluation may consider technical approach, past performance, price, and other factors specified in the request.

  5. 5
    Task order awarded and work begins

    The winning contractor receives a task order under the GWAC and begins performance according to the terms established. The GWAC prime contract governs overall terms while the task order specifies the particular work scope and deliverables.

Strategies for Winning GWAC Task Orders

  • Monitor task order opportunities actively through GWAC portals, agency procurement forecasts, and industry intelligence sources
  • Develop modular technical content that can be quickly adapted for different task order requirements
  • Build past performance specifically relevant to common GWAC task order types in your target agencies
  • Establish competitive labor rates that meet GWAC requirements while remaining competitive for task order selection
  • Cultivate relationships with agency IT leaders and program managers to understand upcoming requirements
  • Invest in clearances and certifications commonly required for GWAC task orders in your target markets
