How OASIS+ compares to OASIS Legacy

The OASIS+ family of contracts builds on the success of the OASIS and OASIS SB contracts, offering federal agencies access to highly qualified contractors for their comprehensive and complex non-IT services solutions worldwide.

Provide a single solution for complex requirements
Support multiple technical disciplines and mission spaces
Support commercial and non-commercial acquisition
Support all contract types, including hybrids and cost-reimbursement, at the task order level
Allow ancillary support components, commonly referred to as other direct costs, or ODCs, at the task order level
