USNS CESAR CHAVEZ (T-AKE 14) Mid-Term Availability (MTA)The USNS CESAR CHAVEZ (T-AKE 14) Mid-Term Availability (MTA) solicitation, numbered N6264926RL014, is a hybrid contract issued by NAVSUP Fleet Logistics Center Yokosuka for performance between December 15, 2026, and February 2, 2027, with an optional extension through February 17, 2027. Work is to be performed at the contractor’s facility within the U.S. 7th Fleet Area of Responsibility, with explicit prohibition of any performance in India. The contract combines Firm-Fixed Price (FFP) terms for the base MTA work and Time and Materials (T&M) Not-to-Exceed (NTE) CLINs for anticipated growth, with a total materials NTE ceiling of $747,274.83 and labor hours capped at 8,813. This acquisition follows the Lowest Price Technically Acceptable (LPTA) evaluation methodology, where proposals must meet minimum acceptable standards in Technical, Past Performance, and Responsibility factors to be considered, with award going solely to the lowest-priced compliant offeror. Technical evaluation focuses on understanding and executing the Work Item Package, including engineering, material control, weather contingency plans, staffing, facilities, certifications, and quality assurance systems, while past performance must be deemed acceptable or unknown—never unacceptable—based on Navy-relevant work completed within the last five years. Offerors must be actively registered in SAM.gov, possess a valid Unique Entity Identifier, and comply with a broad array of Federal Acquisition Regulation (FAR), Defense Federal Acquisition Regulation Supplement (DFARS), and Navy Marine Corps Acquisition Regulation Supplement (NMCARS) clauses, including requirements for whistleblower protections, trafficking in persons compliance, cybersecurity safeguards, hazardous waste management, and prohibitions on employment of active Navy personnel or procurement from restricted regions such as Xinjiang or entities linked to the Maduro regime. Proposals must be structured into four distinct volumes—Price, Technical, Past Performance, and Cover Page—with strict formatting rules prohibiting cross-contamination of pricing data and requiring all submissions to be in English, unpassworded, virus-scanned, and submitted via DoD SAFE if over 7MB. The solicitation mandates submission of extensive documentation via secure channels, including the Work Item Package, Contractor Price Breakdown, Quality Assurance Surveillance Plan, Contract Administration Plan, and OEM support letters, none of which are publicly available.
