General Services Administration Releases Final OASIS+ Solicitation 

The General Services Administration (GSA) has released the final solicitations for the unrestricted, small business, 8(a), WOSB, SDVOSB, and HUBZone One Acquisition Solution for Integrated Services Plus (OASIS+) multiple agency contract (MAC). The OASIS+ MAC is the successor to the successful OASIS vehicle awarded in 2014.

Similar to the original OASIS, the goal of OASIS+ is to provide government agencies easy and efficient access to innovative services from highly qualified businesses.  GSA has designed OASIS+ to consolidate several other vehicles and create a more expansive and flexible offering.  

Key Details of OASIS+

  • Period of Performance: 10 Years
  • Number of Awardees: No limit 
  • Ceiling: Unlimited
  • Evaluation Method: Scorecard-based with credits from a combination of project experience and corporate certifications
  • On-Ramps:  GSA's goal for OASIS+ is to hold frequent on-ramping (unlike the limited on-ramping that occurred under OASIS)
  • Domains:  8 total domains (see below)
  • Minimum Awards: Awardees will be required to achieve $250k within the first five years to remain on the vehicle

OASIS+ Solicitation Schedule and Contract Families

GSA does not consider OASIS+ a direct follow-on to OASIS because it includes a wider range of services. OASIS+ will combine some offerings currently available under the OASIS, Building Maintenance and Operations (BMO), and Human Capital and Training Solutions (HCaTS) vehicles and include additional new offerings.  Companies can qualify for multiple domains based on their self-scoring submissions.  
OASIS+ includes services in the following domains. 

  1. Technical and Engineering (OASIS)
  2. Management and Advisory (OASIS)
  3. Intelligence (Expanded Scope)
  4. Research & Development (OASIS)
  5. Enterprise Solutions (Expanded scope)
  6. Facilities (BMO)
  7. Environmental (Expanded Scope)
  8. Logistics (OASIS)

GSA has also proposed additional domains to be added to OASIS+ as part of a phase 2:

  1. Financial Services (OASIS)
  2. Business Administration (Expanded Scope)
  3. Human Capital (HCaTS)
  4. Marketing & PR (Expanded Scope)
  5. Social Services (Expanded Scope)

OASIS+ will have six different contract families including:

  1. Unrestricted
  2. Total Small Business
  3. 8(a) Small Business
  4. HUBZone Small Business
  5. Service-Disabled Veteran-Owned Small Business (SDVOSB)
  6. Women-Owned Small Business

Under OASIS+ agencies will first select a contract family and then the domain within that family that meets their requirements.  Each domain has a list of available NAICS within it.


OASIS+ Likely to Become Second Largest Federal Contract Vehicle

Looking at the current OASIS, Building Maintenance and Operations (BMO), and Human Capital and Training Solutions (HCaTS) vehicles, the amount awarded each year has grown significantly, reaching $12 billion in government fiscal year 2022. More than 700 contractors were awarded more than $1 million in awards under a combination of these vehicles in 2022.

Over the last three years, OASIS was the third largest multi-award vehicle by dollars obligated behind only GSA's Multiple Award Schedule (MAS) and NASA's Solutions for Enterprise Wide Procurement V (SEWP V). Given the rapid increase in awards under OASIS and the expanded scope of OASIS+, OASIS+ may become the second largest government contracting vehicle, behind only MAS.

Subcontracting Opportunities on OASIS+

For many contractors, whether or not they obtain a seat on OASIS+ in all of their target domains and vehicle families, developing relationships with prime awardees under multiple OASIS+ families and domains may be even more critical to long-term success through the vehicle given its significant subcontracting goals. These subcontracting goals include:

  • Small Business: 50%
  • Small Disadvantaged Business: 7%
  • Woman-Owned Small Business: 7%
  • HUBZone: 3%
  • Veteran Owned Small Business: 3%
  • Service-Disabled Owned Small Business: 3%

This high level of subcontracting was seen on the previous predecessor vehicles as well, with approximately $35.1 billion subcontracted out of a total of $58.2 billion in prime awards over their lives to-date.
