About this opportunity
The General Services Administration (GSA), Federal Acquisition Service, seeks contractors for the One Acquisition Solution for Integrated Services Plus (OASIS+) Unrestricted Indefinite-Delivery, Indefinite-Quantity (IDIQ) Multi-Agency Contract across thirteen professional service domains, with proposals due January 11, 2027 and no set-aside restrictions.
This is Amendment 0009 to solicitation 47QRCA23R0006, a continuously open solicitation supporting rolling admissions. The OASIS+ Unrestricted contract encompasses thirteen domains: Management and Advisory; Technical and Engineering; Research and Development; Intelligence Services; Enterprise Solutions; Environmental; Facilities; Logistics; Business Administration; Marketing and Public Relations; Human Capital; Financial Services; and Social Services. Offerors may propose for one or multiple domains within a single proposal submission.
Contractors must meet domain-specific qualification thresholds measured in credits (42 credits for most domains, 45 for Enterprise Solutions; 36 credits for small business set-asides), demonstrated through qualifying projects with minimum average annual dollar values ranging from $125,000 to $50,000,000 depending on the domain. All contract types are permitted at task order level: fixed-price, cost-reimbursement, time-and-materials, labor-hour, and incentive contracts. The minimum guaranteed contract award is $2,500 over the full term with no maximum dollar ceiling. A Contract Access Fee of 0.15% applies to all invoiced amounts.
Place of performance includes CONUS, OCONUS, and hostile areas. Contractors must provide labor, supervision, facilities, and materials. CONUS standardized labor categories align with Bureau of Labor Statistics Standard Occupational Classifications across four seniority levels (Junior, Journeyman, Senior, Subject Matter Expert), with direct labor hourly rates ranging from $45.80 to $213.23. All pricing includes 4.41% annual escalation over 15 contract years.
Evaluation weights technical approach and past performance; offerors must achieve qualifying project relevance, scale performance, integrated experience spanning functional areas and labor categories, management and staffing capabilities, past performance ratings exceeding 3.0 on a 5-point scale, federal experience in competitive multiple-award environments, and industry certifications (CMMI, ISO standards, CMMC). Subcontracting plans promoting small business participation are required.
Offerors must register in the OASIS+ Submission Portal (OSP) and System for Award Management (SAM.gov). Apparent awardees were notified May 12, 2026; formal awards and notices to proceed were issued on or about May 22, 2026. Contracts are available in GSA eBuy upon contractor registration in the Vendor Support Center.
Amendment 0009 (issued July 7, 2026) revised FPDS references to SAM.gov, updated Cybersecurity and Supply Chain Risk Management Plan submission requirements to 90 days after Notice to Proceed and annually by August 30, clarified IT services as ancillary support, and updated domain qualification matrices and cost/price templates. Offerors with pending offers prior to Amendment 0009 must acknowledge the amendment by July 15, 2026, or face offer ineligibility. The NAICS code is 541990, All Other Professional, Scientific, and Technical Services; PSC is R499, Support-Professional: Other.
