Question 1

What is the difference between a GWAC, an IDIQ, and a GSA Schedule?

Accepted Answer

A GWAC (Government-Wide Acquisition Contract) is a pre-competed, indefinite-delivery contract that any federal agency can use for IT or services. An IDIQ (Indefinite Delivery/Indefinite Quantity) contract is similar but may be limited to one agency or a specific set of agencies. A GSA Multiple Award Schedule (MAS) is a long-term pricing agreement that allows agencies to order commercial products and services at pre-negotiated rates without a standalone competition. GWACs and IDIQs typically require a separate task order competition, while GSA schedule orders can be placed more directly.

Question 2

What are Best-In-Class (BIC) contract vehicles?

Accepted Answer

Best-In-Class (BIC) is an OMB designation for contract vehicles that meet specific criteria for strong terms and conditions, favorable pricing, reporting, and government-wide usage. BIC vehicles include GSA Schedules, OASIS+, STARS III, Polaris, SEWP V, Alliant 3, and CIO-SP4. Agencies are encouraged to use BIC vehicles first before establishing new standalone contracts, making BIC vehicle holders well-positioned across the federal market.

Question 3

Can a company hold multiple contract vehicles simultaneously?

Accepted Answer

Yes. Most federal contractors hold multiple contract vehicles to maximize their market coverage. It is common for a company to hold a GSA MAS schedule (for direct ordering), one or more GWACs (for larger, more complex task orders), and agency-specific IDIQs (for targeted market access). Holding multiple vehicles is not just permitted — it is standard practice for mid-size and large contractors.

Question 4

What is SeaPort-NxG and who can use it?

Accepted Answer

SeaPort-NxG is the Navy's primary multiple-award IDIQ contract for professional services, managed by NAVSEA. It supports engineering, IT, logistics, program management, and other professional services for all Navy and Marine Corps activities, SPAWAR, NETWARCOM, and other DoN commands. Only registered SeaPort-NxG contract holders can compete for task orders issued under the vehicle.

Question 5

What is the difference between OASIS+ Small Business and OASIS+ Unrestricted?

Accepted Answer

OASIS+ has two primary pools: Small Business (SB) and Unrestricted (UNR). The Small Business pool is restricted to companies that meet SBA small business size standards, enabling set-aside competitions. The Unrestricted pool allows any size business to compete and is used for orders that are not set aside. OASIS+ also has sub-pools for 8(a), HUBZone, SDVOSB, and WOSB companies within the small business pool.

Question 6

How does NASA SEWP V differ from the GSA IT Schedule?

Accepted Answer

NASA SEWP V is best suited for commercial IT product procurement (hardware, software, solutions), while the GSA IT Schedule covers both products and IT professional services. SEWP V is known for its very streamlined ordering process — it can be faster than running a separate competition. The GSA IT Schedule has a broader SIN structure and includes more service categories, while SEWP V has a more product-focused scope with a quicker order process.

Question 7

What is the GSA Polaris GWAC and how does it differ from STARS III?

Accepted Answer

Both Polaris and STARS III are GSA small business IT GWACs, but they differ in pool structure and scope. STARS III is structured around three IT task areas (Systems Development, IT Support, Emerging Technologies) and requires 8(a) status for the set-aside pool. Polaris is newer and has pools specifically for WOSB, SDVOSB, and HUBZone companies in addition to a general small business pool, covering a broader set of IT services including cloud, AI, and cyber.

Question 8

What is HCaTS and who manages it?

Accepted Answer

HCaTS (Human Capital and Training Solutions) is a GWAC jointly managed by GSA and OPM (Office of Personnel Management). It covers complex, integrated human capital management and training services for any federal agency. HCaTS has two pools: Pool 1 (Learning Solutions) and Pool 2 (Human Capital Strategy). It has both small business and unrestricted tracks, and is used by agencies for workforce development, leadership training, organizational development, and HR consulting.

Question 9

How does NIH CIO-SP4 compare to SEWP V?

Accepted Answer

NIH CIO-SP4 is managed by NITAAC and is primarily a services vehicle (IT services, health IT, data analytics, AI/ML), while NASA SEWP V is mainly a products vehicle. CIO-SP4 has significantly higher volume potential for services-oriented IT companies. Both are BIC-designated GWACs available to all federal agencies, but CIO-SP4's health IT focus makes it especially useful for HHS components, VA, and agencies with health IT needs.

Question 10

What is GSA Alliant 3 and when will it be available?

Accepted Answer

GSA Alliant 3 is the planned successor to GSA Alliant 2 — the government's largest IT GWAC by ceiling ($50B+). Alliant 3 will cover all IT services and solutions for unrestricted large business competition. As of 2025-2026, GSA is in the final stages of awarding Alliant 3 contracts. Companies should monitor GSA acquisition forecasts for Alliant 3 award announcements. Alliant 2 remains active through its ordering period end.

Question 11

How does SamSearch help with GWACs and contract vehicles?

Accepted Answer

SamSearch aggregates task order opportunities from all major contract vehicles — including eBuy (for GSA vehicles), SeaPort portal, SEWP, and SAM.gov — in a single dashboard. The platform sends real-time alerts when task orders matching your vehicle contracts and capabilities are issued, tracks expiring task orders for recompete opportunities, and provides spending intelligence on which agencies are most actively buying through each vehicle.

Question 12

Do I need to register in SAM.gov separately for each contract vehicle?

Accepted Answer

SAM.gov registration is required for all federal contractors regardless of the vehicle they hold. However, each GWAC and IDIQ may require separate registration in a vehicle-specific portal — for example, SEWP has its own contractor portal, SeaPort-NxG has its own ordering portal, and OASIS+ task orders flow through the GSA eBuy system. You maintain one active SAM.gov registration but must stay current in each vehicle's portal.
