OASIS One Acquisition Solution for Integrated Services (OASIS) - The OASIS Program is composed of multiple award indefinite delivery/indefinite quantity (MA-IDIQ) contracts. The contract consists of a base period of five (5) years with one (1) five year option period. The purpose of OASIS SB is to meet the needs of customers with complex integrated professional service based requirements who cannot use, or find difficulty using, the MAS Schedules, Government-wide Acquisition Contracts (GWACs), or other existing vehicles for a solution. Complex integrated professional services based requirements are those that:

-Involve multiple professional services disciplines;
-Involve significant IT components, but are not IT requirements;
-Involve ancillary support services and supplies (commonly referred to as Other Direct Costs - ODCs);
-Involve commercial or non commercial services, or a blend of both;
-Require consideration of all Federal Acquisition Regulation (FAR) Part 16 pricing alternatives, including fixed-price with or without incentives, cost-reimbursement (all types), Time-and Material, Labor-Hour, or combinations of these alternatives, to fairly allocate risk between the contractor and Government; and
-Require blending of all or some of the above.
