This is an amendment for the OASIS+ Unrestricted IDIQ contract, which is a continuously open solicitation supporting rolling admissions for multiple service domains. There is no fixed award timeline, as it will vary based on proposal volume and resource availability. All proposals must be submitted through the OASIS+ Symphony Portal, which opened for registration and offer submission on January 12, 2026. Offerors must be registered in SAM.gov and are permitted to submit a single proposal for multiple domains. The official solicitation requirements and amendments are posted on SAM.gov, which takes precedence over all other sources.
