About this opportunity
NASA Ames Research Center issued this Limited/Sole Source Justification Notice on April 6, 2026, to extend contract 80ARC021D0001 with Millennium Engineering and Integration Services (MEIS) for Project and Engineering Support Services II (PESS II). The extension provides comprehensive engineering support services including systems engineering, design, development, fabrication, testing, software development, and operations support for critical NASA research facilities such as wind tunnels, laboratories, and test chambers, serving over 20 active NASA missions and projects. NASA justified the sole-source award based on MEIS being the only responsible source capable of performing the highly specialized work without creating unacceptable delays, supported by market research conducted in April 2025 that found two competing vendors (Black Light Consultation and Nine East Tech Services) lacked sufficient capabilities to meet the complex engineering requirements. The contract extension runs for two years from April 1, 2026 through March 31, 2028, structured as a cost-plus-fixed-fee hybrid contract with a firm-fixed-price phase-in component and cost-plus-fixed-fee contract management and technical requirement components. The extension has a maximum potential contract value of $169 million with $33.7 million remaining available under the existing IDIQ contract value, and the contracting officer determined the anticipated costs to be fair and reasonable subject to proposal analysis and negotiation.
Notice text
The purpose of this acquisition is award of an extension to contract number 80ARC021D0001 with Millennium Engineering and Integration Services (MEIS). Thecontract extension consists of one twelve-month base year and two six-month option periods for a total of two (2) years (from April 1, 2026, through March 31, 2028). NASA ARC competitively awarded contract number 80ARC021D0001 on December 14, 2020, with a period of performance effective date of January 31, 2021, through March 31, 2026. The contract is a cost-plus-fixed-fee (CPFF) hybrid contract consisting of firm-fixed price (FFP) contract line-item number (CLIN) for phase-in; and CPFF CLINs for contract management, core technical, and indefinite delivery/indefinite quantity (IDIQ) requirements. The PESS II contract provides engineering support services for NASA ARC to meet NASA’s mission goals. It includes requirements for support of the design and proposal of new mission concepts, and the design, development, manufacture, and demonstration of cost-efficient engineering products. The contract also provides support in operation of ARC’s critical state-of-the-art research facilities including research laboratories, aerospace/aeronautics facilities (e.g., airfield/hangars, wind tunnels, arc jets, and simulators), computer laboratories, ballistic ranges, general testing facilities, fabrication facilities (e.g., machine shops, metal shops, and model shops), flight/mission operations facilities, and test chambers.
The Justification for Other than Full and Open Competition (JOFOC) for this action was prepared, approved, and attached to this notice.
Awarded contract 80ARC021D0001 to unknown vendor for unknown amount on 2026-03-30.
