General Overview of OASIS SB


One Acquisition Solution for Integrated Services – Small Business (OASIS SB) is designed to address agencies’ need for a full range of service requirements that integrate multiple professional service disciplines and ancillary services/products with the flexibility for all contract types and pricing at the task order level.

OASIS SB is a family of seven separate Government-wide Multiple Award, Indefinite Delivery, Indefinite Quantity (MA-IDIQ) task order contracts that span 28 North American Industry Classification System (NAICS) Codes and 6 NAICS Code Exceptions under the economic subsector 541, Professional, Scientific, and Technical Services. These contracts are collectively referred to as a single contract called “OASIS SB”. Additionally, each of the seven separate contracts are individually referred to as “Pools” within OASIS SB. APT is a prime under Pool 3 for engineering services, NAICS code 541330.

The services to be provided under OASIS SB are intended to meet the professional service mission requirements of all Federal agencies, including all organizations within the Department of Defense (DoD) and National Security Community.


The objective of OASIS SB is to provide Government agencies with total integrated solutions for a multitude of professional service based requirements on a global basis.

These professional service requirements may call for solutions that cross over multiple disciplines, include ancillary support, and require commercial and/or non-commercial items, using a variety of contract types including fixed-price (all types), cost reimbursement (all types), time and materials/labor hour, or a hybrid mix of contract types.

OASIS SB is available for use by all Federal agencies and other entities as listed in General Services Administration (GSA) Order ADM 4800.2G, Eligibility to use GSA Sources And Supply; as amended.
