NEW: GSA Releases Phase II and Continuous On-Ramping with Amendment 0008

On Jan. 13, 2026, GSA released the final RFP amendments for Phase II! This final RFP introduces five new domains, bringing the total to 13.

OASIS+ Phase II RFPs

The six final solicitations include the following set-asides and unrestricted contracts:

• Total Small Business (SB)
• SBA-Certified 8(a) SB (8[a])
• SBA-Certified HUBZone (HZ)
• SBA-Certified Service-Disabled Veteran-Owned SB (SDVOSB)
• SBA-Certified Women-Owned SB (WOSB)
• Unrestricted (UR)

Who can bid on OASIS+ Phase II?

You are in the right place if one of the following situations describes you:

1.  “New” Offerors: This describes you if you do notcurrently have an active OASIS+ contract and are looking to get one (in any domain). This group may include companies that submitted unsuccessful bids in the first round of proposal submissions.
2.  Current OASIS+ Contract Holders looking for more IDIQs, aka “Lateral Springboards”: This describes you if you were awarded an OASIS+ contract under one socio-economic IDIQ and now qualifyfor another socio-economic category. (There are six separate IDIQs under the OASIS+ program: Unrestricted, Small Business, HUBZone, Service-Disabled Veteran-Owned, 8(a), and Woman-Owned).
3.  Current Contract Holders looking for more Domains, aka “Domain Enhancement”: This describes you if you have an activeOASIS+ contract in any IDIQ and Domain(s) and you are looking to add Domains/CLINs to your IDIQ(s). Remember, under the OASIS+ program, Domains are like functional areas of expertise. Domain Enhancement applies whether you’re looking to add Phase I or Phase II Domains (more on that below), as long as you have an existing OASIS+ contract. 

We drew this out graphically, as we know it’s sometimes easier to see.

Please note, companies cannot hold more than one master contract within any IDIQ.

What’s the biggest difference in Phase I and Phase II?

The biggest change between Phase I and Phase II is that the solicitation is now operating much like a GSA Multiple Award Schedule where it is continuously open for proposals and there will be “rolling” contract awards. While there is currently no closing date for the solicitation (and thus no “due date” for proposals), it is important to note that this does not mean GSA will not amend, modify, or close the any domain or solicitation vehicle. Should this be a necessary action in the future, GSA has said that “the agency will provide public notification with sufficient advance notice.”

With no due date, you may be wondering about how long it will take GSA to make awards. What they shared with the Amendment 0008 release is that “there is no fixed timeline for award; timelines will vary based on the volume of proposals received. Proposals will generally be evaluated in the order they are received, subject to resource availability.”

What else do I need to know about OASIS+ Amendment 0008?

Beyond the shift to a continuously open solicitation, there were a few other notable updates. We’ll cover the highlights first, then dive into the five new domains.

• All offerors must acknowledge Amendment 0008 in their
• If you submitted a bid for Phase I and were unsuccessful, you will need to include a response to the debriefing letter addressing each finding in your new offer. Check out RFP Section L.5.9 Rejection of Previous Offer for more information.
• GSA issued Attachment J.P-14 Lateral Springboard Summary Sheet for existing Phase I contract holders who are requesting to be awarded IDIQs in a set-aside that they now qualify for.

• Qualifying Projects used in Phase I may be reused in Phase II – with some caveats. Projects and documentation used to qualify for Phase I may be leveraged to support Phase II if the projects meet the qualifying criteria of Phase II domains. Phase II bidders will still need to substantiate their self-scores, so providing documentation is key to supporting claims made about experience and capabilities. Supporting projects (and documentation) should be directly relevant to the specific domain(s) you’re targeting in Phase II. Note that a project is still prohibited from being used in two proposals for the same Domain and IDIQ.

• Eligibility for Phase II is not tied to participation in Phase I. You are not required to have won a Phase I IDIQ to participate in Phase II. All interested offerors who meet eligibility requirements are qualified to submit a proposal (Note: If you did win an IDIQ in Phase I, you will be permitted to re-use certain proposal artifacts if you are adding domains to that contract under the Lateral Springboard option.).

• And, of course, there are Five *NEW* Domains. This brings the total number of OASIS+ domains to 13. These domains are:
  • Technical & Engineering (T&E)
  • Research & Development (R&D)
  • Management & Advisory (M&A)
  • Environmental
  • Intelligence Services
  • Facilities Services
  • Logistics
  • Financial Services*
  • Business Administration*
  • Human Capital*
  • Marketing & PR*
  • Social Services*
  • Enterprise Solutions (Note: this domain is in the Unrestricted IDIQ only).

It’s also important to note what did NOT change with Amendment 0008 – namely that OASIS+ will remain a professional services vehicle. GSA did not add software-related NAICS codes to any existing or new domains, reinforcing that OASIS+ will remain a vehicle primarily for professional services, not for Information Technology services/products/support. Additionally, RFP Section C.5, Services Not in Scope, provides more information on which services will NOT be permitted under OASIS+.

Here’s an overview of the contract to date:

Number of Awards by Domain (as of Oct. 6, 2025)

If you’re new to this bid, it’s vital to understand that OASIS+ is a scorecard evaluation, and there is a specific scorecard for EACH Domain. Said another way, you may not receive the same score in the Technical & Engineering Domain that you do in Research & Development because the qualifying criteria vary between the two Domains.

How to Get Ready: Tips to Help you Bid

If you followed any of our other MA-IDIQ or GWAC campaigns, the first thing we ALWAYS recommend is that you ask yourself, “Is OASIS+ the right prime contract for me?” In other words, is it a contract you can realistically manage and that your government clients can/will use? As with all IDIQs, the initial bid is the easy part. Winning work on task orders will require additional time, resources, and effort. We’d encourage a quick “time out” before you start tallying any points to ask yourself a few key qualifying questions:

• Do you have current Federal customers who are using or are likely to use OASIS+ for future acquisitions? (If you don’t know the answer to this question, contact us - our Business Analysts can help!)
• Can you manage the administrative demands of a GSA contract within your current contract support infrastructure?
• Are you willing and able to meet the marketing, minimum contracting thresholds, and participation requirements that come with a win?

Answering “No” to the questions above shouldn’t lead to an automatic “no bid.” However, it should give you pause and help you calibrate your definition of what success looks like on OASIS+. Your goal should be to stay on the contract for the long term and make it work for you, not just secure an initial award. Think through how you will manage work once you’re on the contract, and then let that plan inform your strategic bid, hiring, teaming, or business development decisions.

Another important note regarding contract management. GSA has said that they reserve “the unilateral right to off-ramp non-performing contractors” (source). There are five conditions currently spelled out on their website here. Ensure you can not only bid on the IDIQ but also meet the requirements to remain on it.  

Once you are confident that OASIS+ is a vehicle you can use and manage successfully, we recommend the following steps:

#1: Build a Qualifying Project Tracker. This doesn’t need to be complex, but think of it as a master index for any project you’re considering for OASIS+. You can download our free template here. The point of the tracker is to have a quick-look reference for your projects so that you can tell right away which projects are even considered eligible based on contract/project type, recency, and average annual value.

A tool like this can also help inform your teaming conversations. During Phase I, offerors could use qualifying relevant experience from teammates. If you get “invited” to form a team, this tracker can help you understand where you already have project coverage and where you might need it. That means you can have a very clear, data-driven conversation about what type of qualifying experience will actually enhance your score.

#2: Check on those SAM.Gov registrations and company certifications. Is anything coming due for renewal or at risk of expiring in the next six months? If you are a repeat OASIS+ bidder, has anything changed since you submitted for Phase I (e.g., now you have facility clearance or CMMC Level 2 certification)? Symphony pulls your company data from SAM.Gov, so make sure you take a look at your registrations and representations early.

#3: Register for Symphony. While we don’t encourage new bidders to start uploading files immediately, it is important to get access to the submission portal early. You’ll want access so that you can see how your company information will be organized, how your project data will be cataloged, and how building a proposal within your designated IQIQ(s) and domain(s) will actually work. Plus, you’ll need access to Symphony if you want to ask any questions! You can register using this link: Symphony Procurement Suite. Note: You can use your email address only once, and you’ll need your company’s UEI and CAGE code if you are a new user.

#4: Calculate your self-score (and if applicable, understand what went wrong). The great thing about a scorecard bid like this is that if you do your homework, you’ll know your chances of success before you even hit “Submit” on your proposal. Take some time upfront to do a self-score, and if you need help determining whether you are eligible, contact us! Whether you’re brand new to OASIS+ or are just looking to round out your contract by adding domains, we can help by reviewing your projects through the lens of a GSA evaluator. Also, if you were not successful in your initial Phase I bid, it is CRITICAL that you understand why you did not receive an award before you submit for Phase II. If you need help understanding your notice or reviewing your proposal, contact us!  Want a second set of eyes? We can help!
