GSA OASIS+ Program

The One Acquisition Solution for Integrated Services (OASIS)+ Multi-Agency Contract (MAC) is a government-wide, multiple-award, Indefinite Delivery, Indefinite Quantity (IDIQ) acquisition program for complex professional services (Non-IT) and innovative solutions from highly qualified firms on a contract vehicle designed to be the next generation Best-in-Class (BIC) contract.

OASIS+ Proposal Preparation Support

The Gormley Group (TGG) provides advisory and consulting services to assist you in capturing an OASIS+ contract. As part of this effort TGG will deliver expert direction in the development of offer materials, map services to the applicable OASIS+ Master contracts and domains, and conduct a comprehensive final review of the OASIS+ offer prior to submission. TGG will also work with you and GSA through contract award and any subsequent contract management efforts in the future.

OASIS+ Program Highlights

The OASIS+ Program will award contracts designated under the following small business socio-economic categories. In addition to the small business contract categories there is also a full unrestricted category primarily designated for large businesses. Below is the list of all available contract categories:

  • Total Small Business
  • 8(a) Small Business
  • HUBZone Small Business
  • Service-Disabled Veteran-Owned Small Business
  • Woman-Owned Small Business
  • Unrestricted

The OASIS+ program is designed to address Federal agency needs for a full range of service requirements that integrate multiple service disciplines and ancillary services/products with the flexibility for commercial and non-commercial requirements, all contract types including Cost-Reimbursement contracts, and pricing at the task order level and achieve a total solution. Additional OASIS+ program highlights include:

  • GSA identifies each award contract as a “Master” contract.
  • OASIS+ Master contracts do not have established pricing; pricing is established at the task order level.
  • OASIS+ Master contracts will have a 10-year consecutive period of performance from initial award.
  • GSA plans a continuous open season provision as part of the OASIS+ program subsequent to initial awards.
  • For companies that fall under more than one small business designation, these contractors must submit an offer for each small business Master contract individually.
  • OASIS+ will not have a total-dollar ceiling (the limit of spending for all task orders on the contract) in place.

The OASIS+ program will initially include the following eight Domains. GSA may introduce additional domains in the future. Only vendors providing the below services will be eligible for the initial OASIS+ contracts:

1. Management and Advisory Domain 5. Enterprise Solutions Domain (Unrestricted ONLY)
2. Technical and Engineering Domain 6. Environmental Domain
3. Research and Development 7. Facilities Domain
4. Intelligence Service Domain  8. Logistics Domain
