The Naval Facilities Engineering Systems Command Hawaii intends to award a sole-source modification to extend an existing IDIQ contract for an additional 5.5 months, from September 16, 2026 through February 28, 2027, as a temporary bridge to maintain uninterrupted services. Work will be performed at Joint Base Pearl Harbor-Hickam and other Oahu, Hawaii locations. The contract covers labor, materials, and services for operation, maintenance, and installation of critical systems including autoclaves, boilers, air compressors, liquid nitrogen systems, and wastewater treatment. Potential sources must demonstrate OEM certifications, personnel with active security clearances for immediate base access, and a mobilization plan showing full capability with zero transition gap. This notice is not a request for proposals, but the government will consider capability statements to determine if competitive procurement is warranted.
