Government-Wide Acquisition Contract (GWAC)
A federal IDIQ contract designated by OMB for use by all federal agencies — typically for IT and technology services.
Definition
A GWAC is an IDIQ contract authorized for use across multiple federal agencies. GWACs are administered by designated Executive Agents — typically GSA, NASA, or NIH — and focus heavily on IT and technology services. Examples include GSA OASIS+ (professional services), GSA Alliant 2 (IT services), NASA SEWP (IT products), and NIH CIO-SP (IT services for health agencies).
When it applies
Winning a GWAC slot positions a vendor to compete for task orders worth tens or hundreds of millions of dollars across many agencies, often for ten years or more. The application process is highly competitive and typically requires substantial past performance, financial strength, and a teaming structure.
