GSA OASIS+ Contract Vehicle

The General Service Administration (GSA) One Acquisition Solution for Integrated Services+ (OASIS+) provides Federal Government Agencies with an in-place contract vehicle for requirements that integrate multiple professional disciplines, services, and products. Because the OASIS+ contract vehicle is already in place, the time from solicitation to award is approximately 60 days—far faster than traditional government procurement timelines. Federal Agencies such as DoD, NASA, DoT, DHS, EPA, DOE, CIA, and many others can directly contract using the OASIS+ vehicle under Delegation of Procurement Authority letters already issued by GSA. Alternatively, a Government Agency can request GSA assist in conducting the procurement.

The GSA’ OASIS+ is the largest multi-agency contract program for professional services. The OASIS+ scope covers a wide array of domains defined as: Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental, Facilities, Logistics, and Enterprise Solutions.
OASIS+ offers six Indefinite Delivery Indefinite Quantity (IDIQ) schedules:
- Total Small Business
- Women-owned Small Business
- Service Disabled Veteran-Owned Small Business
- HUBZone Small Business
- 8(a) Small Business, and
- Unrestricted
GSA OASIS+ Schedule | ES3 Contract Number |
---|---|
Total Small Business | 47QRCA25DS076 |
Women-owned Small Business | 47QRCA25DU590 |
Unrestricted | 47QRCA24DW152 |
The ordering period for each of ES3’s OASIS+ Contracts began in 2025 with a five-year base period plus one five-year option period for a total of ten years. These OASIS+ contracts can accommodate Firm Fixed Price (FFP), Cost Plus Fixed Fee (CPFF), Time and Material (T&M) and hybrid types of awards.

Unlike most Indefinite Delivery Indefinite Quantity (IDIQ) contract vehicles, teaming on OASIS+ is determined at the task order level. This gives ES3, as the OASIS+ prime contractor, total flexibility regarding teaming during the procurement process and subcontracting after task order award.
