Definition
A Governmentwide Acquisition Contract (GWAC) is a pre-competed, multiple-award, Indefinite Delivery/Indefinite Quantity (IDIQ) contract for information technology goods and services that any federal agency can use, without having to run its own full competitive procurement process.
In simple terms, a GWAC is a pre-approved shopping platform for federal IT. The hard work of vetting vendors, negotiating terms, and ensuring compliance has already been done. Any federal agency can plug in and start buying.
Key Characteristics of a GWAC
- Pre-competed: The base contract is competed once, upfront. Vendors go through a rigorous evaluation before being awarded a spot on the GWAC.
- Multiple award: Multiple vendors are selected, creating a pool from which agencies issue individual task orders, maintaining ongoing competition.
- IDIQ structure: No guaranteed volume at the base level. Agencies place task orders as needs arise, up to the contract's ceiling value.
- IT-specific: GWACs are specifically authorized for information technology solutions, hardware, software, services, and related professional support.
- Governmentwide use: Any federal agency can use a GWAC, not just the agency that manages it.
- Best-in-Class designation: GWACs recognized by the Office of Management and Budget (OMB) as Best-in-Class (BIC) vehicles meet the highest standards for cost-effectiveness, security, and socioeconomic goals.
- Delegation of Procurement Authority (DPA): Before using a GWAC, an ordering agency must obtain a DPA from the GWAC program office, confirming its requirement falls within the contract's scope.
3 Major Parts of GWACs That Vendors Should Know
A. GSA-Managed GWACs
Alliant 3 (New, Phase I awards issued March 2026) GSA's flagship unrestricted GWAC for complex, enterprise-wide IT solutions. Designed for large-scale IT modernization, cybersecurity, cloud, and systems integration. Open to all federal agencies. 🔗 gsa.gov/alliant3
Alliant 2 (Still active) The predecessor to Alliant 3, with an $82.5 billion ceiling and ordering period through June 2028. Covers end-to-end IT solutions, including hardware, software, and services.
Polaris (Small Business GWAC) A small business set-aside GWAC with four socioeconomic pools: Small Business, HUBZone, Women-Owned Small Business (WOSB), and Service-Disabled Veteran-Owned Small Business (SDVOSB). Focused on customized IT services. 🔗 gsa.gov/polaris
8(a) STARS III Set aside exclusively for SBA-certified 8(a) businesses. Has a $50 billion program ceiling. Supports a wide range of IT services, including emerging technologies, with sole-source task order capability below certain thresholds.
VETS 2: The only GWAC set aside exclusively for Service-Disabled Veteran-Owned Small Businesses (SDVOSBs). Covers IT services and cybersecurity with a $6.1 billion ceiling through 2033.
B. NASA-Managed GWAC
SEWP (Solutions for Enterprise-Wide Procurement) is one of the most widely used GWACs in the federal government. Focused on commercial IT products, product-based services, and emerging technologies. Over 140 pre-competed prime contract holders, including more than 100 small businesses. Available to all federal agencies. 🔗 sewp.nasa.gov
C. NIH-Managed GWACs
CIO-SP3 (Chief Information Officer, Solutions and Partners 3) Managed by the NIH Information Technology Acquisition and Assessment Center (NITAAC). Covers a wide range of IT services and solutions for both civilian and DoD agencies.
The Simple Explanation
Imagine a federal agency needs to modernize its data infrastructure, improve cybersecurity, and migrate legacy systems to the cloud, all at once. Running three separate full and open competitions would take months and consume enormous staff time.
Instead, the agency taps into a GWAC like Alliant 3 or NASA SEWP. The vendors on those contracts have already been pre-qualified, the contract terms are already set, and the agency simply issues a task order against the GWAC. The entire procurement can be completed in days or weeks instead of months.
That is the core value of a GWAC, speed, compliance, and access to a pre-vetted pool of qualified IT vendors.
How a GWAC Works: Step by Step
- A federal agency identifies an IT need, such as cloud migration, cybersecurity, software development, etc.
- The agency obtains a Delegation of Procurement Authority (DPA) from the GWAC program office.
- The agency issues a Request for Task Order Proposals (RFTOP) or Request for Quotes (RFQ) to the GWAC vendor pool.
- Pre-qualified vendors submit proposals or quotes.
- The agency evaluates responses and awards a task order to the best value vendor.
- Work begins, often within days or weeks of the initial need being identified.
GWACs vs. GSA Schedules: What Is the Difference?
Both GWACs and GSA Multiple Award Schedules (MAS) are pre-competed vehicles available governmentwide, but they are not the same thing.
- GWACs are specifically authorized for IT solutions and require OMB designation. They involve a rigorous vendor qualification process and are structured around complex, enterprise-level requirements.
- GSA Schedules (MAS) cover a much broader range of categories, from IT to professional services to office supplies, and are generally accessed at or below schedule prices with less formal competition at the order level.
- GWACs are considered Best-in-Class vehicles; GSA Schedules are widely used but do not always carry that designation.
- For complex, large-scale IT programs, agencies increasingly prefer GWACs over Schedules because of the deeper vendor vetting and more structured competition at the task order level.
Why Vendors Should Care About GWACs
Winning a spot on a GWAC is one of the most strategically valuable moves an IT vendor can make in the federal market. Here is why:
- Access to every federal agency: A single GWAC award opens your business to procurement officers across the entire federal government, without needing to win individual agency contracts.
- Reduced competition at the order level: Once on a GWAC, you compete only against other GWAC holders, not the entire market.
- Streamlined sales cycle: Agencies can move from need identification to task order award much faster through a GWAC than through a full open competition, meaning faster revenue for vendors.
- Best-in-Class credibility: Being on a BIC GWAC signals to agencies that your company has been rigorously vetted for technical capability, past performance, and compliance.
- Small business opportunities: Several GWACs, Polaris, 8(a) STARS III, VETS 2, are specifically set aside for small businesses, giving qualifying firms a competitive advantage.

- The Contract Access Fee (CAF) for GWACs like Alliant 2 is just 0.75% of the total order value, making them cost-effective for agencies compared to running their own procurements. (Source: AFCEA)
Common Terms Associated with GWACs
GWACs and the SLED Market: What Vendors Should Know
GWACs are strictly federal vehicles, state and local governments cannot use them directly. However, there are important connections between GWACs and the SLED market that vendors should understand:
- NASA SEWP Cooperative Purchasing: In certain circumstances, state, local, and tribal agencies may be eligible to access SEWP contracts through cooperative purchasing provisions, bridging the federal and SLED markets.
- SLED equivalents: The SLED market has its own versions of GWACs, cooperative purchasing vehicles like NASPO ValuePoint, Sourcewell, and OMNIA Partners function in a very similar way: pre-competed, multiple-vendor contracts that any eligible SLED agency can use without running its own solicitation.
- Subcontracting opportunities: Even if your company is not a GWAC prime, you can participate in federal IT programs as a subcontractor to a GWAC prime holder, a common path for smaller vendors entering the federal market.
- GSA Schedule + SLED: Unlike GWACs, GSA Multiple Award Schedules do allow state and local purchasing through the Cooperative Purchasing Program, making MAS a more accessible federal vehicle for vendors targeting both federal and SLED buyers.
Quick Summary
A GWAC is a pre-competed, multi-vendor IDIQ contract for federal IT procurement that any agency can use without running its own full solicitation. Major GWACs include GSA's Alliant 3, Polaris, 8(a) STARS III, VETS 2, NASA SEWP, and NIH CIO-SP3. For IT vendors, winning a GWAC is one of the highest-value strategic moves in federal contracting, providing access to the entire federal market, reduced competition at the task order level, and Best-in-Class credibility. In the SLED market, cooperative vehicles like NASPO ValuePoint serve a similar purpose.
