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.
