JUSTIFICATION FOR OTHER THAN FULL AND OPEN COMPETITION

(JOFOC)

FOR Test Facilities Operations, Maintenance & Engineering II (TFOME II)

NNC15BA02B

1. Federal Acquisition Regulation (FAR) 6.104-1(a)(1) – Identification of the agency and the contracting activity, and specific identification of the document as a “Justification for other than full and open competition.”
This document is a justification for other than full and open competition prepared by National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC). The procuring agency is NASA, and the contracting activity is GRC. 2. FAR 6.104-1(a)(2) – The nature and/or description of the action being approved: This justification provides the rationale for contracting by other than full and open competition to award a sole-source extension of three, one-month extension periods to contract number NNC15BA02B with HX5 Sierra, LLC (HX5 Sierra) for Test Facilities Operations, Maintenance & Engineering (TFOME II) services at NASA GRC. The current TFOME II contract period of performance, inclusive of all options, six-month extension, and previous two-month deviation, is May 1, 2015, through December 31, 2025. On September 12, 2025, NASA GRC awarded the Test Facilities Operations, Maintenance & Engineering III (TFOME III) contract, which is the follow-on contract to TFOME II. TFOME III has a two-month phase in period and its planned start date at the time of award was January 1, 2026. Phase-out of TFOME II was previously planned to be completed by December 31, 2025.
However, due to the lapse of Government funding on October 1, 2025, and the resulting Government shutdown from October 1, 2025, through November 12, 2025, the phase-out of TFOME II and the phase-in of TFOME III was postponed. The new phase-in period for TFOME III is December 1, 2025, through January 31, 2026. To account for this change to phase-in, it is anticipated the TFOME III contract’s start date will be changed from January 1, 2026, to February 1, 2026.
An extension of TFOME II is necessary to ensure continuity of testing operations at GRC until the TFOME III contract is fully implemented on the new planned start date of February 1, 2026.

This is a time only extension and the contract value will not be increased. NASA GRC is requesting the following three, one-month extension periods: •
