Attachment 2 - Brand Name Justification and Approval _Redacted.pdf

This is a Single Source Justification (Simplified Acquisition) document for a federal contract action by the 356th Engineering and Installation Squadron (ETSG/CONS).

The requirement is for a 500kW XQ570 Caterpillar Generator Set, including trailer and double-walled fuel tank with 110% spill containment, to be delivered to Guam. The generator will power warehousing operations supporting INDOPACOM construction priorities while meeting specific environmental and operational constraints for Guam, including emissions standards and spill containment requirements. The Caterpillar XQ570 is the only generator model that meets the required power output specifications, environmental compliance standards, and integrated spill containment design necessary for Guam operations. The generator is commercially available and includes local authorized dealer support (Hawthorne CAT) and readily available replacement parts on Guam, minimizing lead times for mission continuity. No life cycle support or ongoing maintenance is included; the contract covers only delivery and installation.

Market research included a Sources Sought notice generating responses from 10 vendors, including several small businesses. Although other generators were considered, they either failed to meet Guam's environmental requirements, lacked local support capabilities, or did not comply with emissions standards. The solicitation will be issued as an open market, small business set-aside to maximize competition among qualified small businesses capable of supplying the specified Caterpillar generator. The contracting officer determined on April 24, 2026, that only a single source is reasonably available under FAR 13.106-1(b)(1).
