Contract Vehicles & The Hidden Market
Where The Real Federal
Work Actually Lives.
Most small businesses are taught to chase SAM.gov solicitations. The truth is that the largest, most consistent dollars in federal contracting move through long-term contract vehicles — IDIQs, MATOCs, SABER, NAVFAC — and through a subcontracting portal almost nobody outside the industry has heard of. We position our clients on both fronts.
The Vehicles That Move The Money
IDIQs, MATOCs, SABER, and NAVFAC.
A federal contract vehicle is a pre-negotiated, multi-year agreement that lets agencies issue task orders quickly without re-running a full open competition every time. If you are not on the right vehicles, you are not invited to compete for the work that flows through them — full stop.
IDIQ — Indefinite Delivery / Indefinite Quantity
The foundational federal vehicle. An IDIQ establishes a ceiling value, a base period, and a pool of qualified contractors. Individual task orders are then competed only among the awardees on that vehicle — not the open market. Getting on the right IDIQs is how mid-size federal contractors build predictable revenue.
MATOC — Multiple Award Task Order Contract
A specific class of IDIQ used heavily by USACE, NAVFAC, and the Air Force for construction, design-build, and facilities work. A MATOC pool typically holds five to fifteen contractors competing internally for task orders worth millions to hundreds of millions over the life of the vehicle.
SABER — Simplified Acquisition of Base Engineering Requirements
The Air Force's primary vehicle for installation maintenance, repair, and minor construction. SABER awardees compete for sustained, high-frequency task orders at a single base — exactly the kind of recurring revenue stream a small business needs to graduate into a real federal operator.
NAVFAC — Naval Facilities Engineering Systems Command
The Navy's facilities and engineering command, and one of the largest sources of MATOC and IDIQ work in the federal government. NAVFAC issues construction, environmental, and engineering task orders worldwide. A NAVFAC seat is one of the most valuable positions a small business contractor can hold.
Why It Matters
The Difference Between Bidding and Being Invited.
A contractor without vehicles is competing against the entire market on every solicitation. A contractor with vehicles is competing against only the other awardees on that vehicle — often three to ten companies — for work that may never appear on SAM.gov at all.
Smaller Competitive Pool
Task orders inside a vehicle are competed only among the awardees. A pool of eight contractors fighting for a $4M task order is a fundamentally different game than two hundred bidders on an open SAM.gov solicitation.
Recurring Revenue
Vehicles run five, seven, sometimes ten years. Once you are on, the task orders keep coming. This is the foundation of a federal contracting business that doesn't have to start from zero every fiscal quarter.
Past-Performance Compounding
Every task order completed on a vehicle becomes documented past performance for the next. CPARs accumulate, relationships with COs and CORs deepen, and your win rate on follow-on vehicles climbs accordingly.
The Hidden Federal Market
SubNet — The Largest Subcontracting Portal In The World.
SubNet is the SBA's federal subcontracting opportunities portal — the single largest registry of subcontracting solicitations posted by federal prime contractors anywhere on Earth. Every large prime with a federal subcontracting plan is required to post opportunities there. And the overwhelming majority of that work never appears on SAM.gov.
Required By Federal Law
Under FAR 19.7 and the Small Business Subcontracting Program, large prime contractors holding federal contracts above the threshold are required to maintain a small business subcontracting plan — and to post qualifying opportunities on SubNet. This is not optional outreach. It is regulated procurement infrastructure.
Most Of It Skips SAM.gov
Subcontracting opportunities posted on SubNet are awarded by primes, not the government directly — so they do not appear on SAM.gov. A contractor watching only SAM.gov is, by definition, blind to the largest pool of small business work in the federal market.
Where Vehicles Get Subcontracted
When a prime wins a large IDIQ, MATOC, SABER, or NAVFAC task order, much of the work gets subcontracted to small businesses. Those subcontracts are sourced through SubNet and through direct prime relationships — not through SAM.gov reposts.
Our Method
How GCAS Markets You To The Right Primes.
We don't just register you on SubNet and walk away. We treat the prime contractor community as the actual customer — because for subcontracted work, they are. We position your capabilities directly in front of the primes most likely to need them on the vehicles they already hold.
Identify The Right Primes
We map the prime contractors holding the IDIQ, MATOC, SABER, and NAVFAC vehicles relevant to your specialty — and the regions where they are actively performing. This is who actually needs to know you exist.
Build A Targeted Capabilities Package
A capabilities statement tuned for primes is not the same document you send to a contracting officer. We rebuild it for the prime audience — set-aside qualifications front and center, bonding capacity, geographic coverage, past performance on vehicles they recognize.
Direct Outreach & SubNet Positioning
We work the SubNet feed daily for matches and run direct outreach to small business liaison officers (SBLOs) at the primes we have already identified. Most of our wins for subcontract work come from being on a prime's short list before a solicitation is ever posted.
Convert Subcontracts Into Prime Position
Subcontracts build the past performance and the relationships that get you onto the next vehicle as a prime. The goal isn't to stay a sub — it's to use SubNet as the on-ramp to your own seat on an IDIQ.
Questions We Hear Often
Vehicles & SubNet FAQ.
Do I have to be a prime contractor to get on an IDIQ or MATOC?
No. Many IDIQs and MATOCs are reserved as small business set-asides — 8(a), HUBZone, WOSB, SDVOSB pools — where small businesses compete directly for prime awards on the vehicle. We help clients identify which set-aside vehicles are open for proposal, qualify for them, and submit competitive bids.
How is SubNet different from SAM.gov?
SAM.gov posts solicitations issued by the government directly. SubNet posts subcontracting opportunities issued by prime contractors who are fulfilling their federal subcontracting plans. The two portals serve different markets, and the SubNet market is significantly less crowded because most small businesses don't know to look there.
Why don't more small businesses use SubNet?
Because nobody tells them about it. SAM.gov is what every consultant, podcast, and YouTube tutorial points to. SubNet is industry knowledge — it is the portal that procurement professionals and prime small business liaison officers actually live in. We give our clients a guided seat in that world from day one.
What about NAVFAC specifically — what kind of work flows through it?
NAVFAC is the Navy's facilities and engineering command. Construction, repair, environmental remediation, design-build, utilities, mechanical, electrical, civil — virtually every trade we list on the Specialties page is procured through NAVFAC vehicles somewhere in the world. It is one of the most dollar-rich procurement commands in the federal government.
Can GCAS get me on a specific IDIQ I'm targeting?
If the IDIQ is open for proposal and you qualify, yes — that becomes a capture engagement. If the IDIQ is already awarded and closed, we pivot you to the prime contractors holding seats on it and pursue the work as a subcontractor through SubNet and direct prime outreach. Either way, the vehicle is the target.

If you are still relying on SAM.gov as your primary opportunity feed, you are missing the largest small business market in federal contracting. Let's audit your current pipeline, identify the vehicles you should be on, and put you in front of the primes who already hold them.
