Attachment 5 - JnA Brand Name Cummins ISL9 Engine-redacted.pdf

This is a Justification for an Exception to Fair Opportunity or Use of Brand-Name Restriction document submitted by the 90th Contracting Squadron at F.E. Warren Air Force Base.

The justification authorizes a brand-name restriction for procurement of a Cummins ISL9 450 replacement engine for Fire Department Ladder Truck serial number 11C00445 under contracting activity 90CONS. The procurement is classified as an individual determination applicable to an operational program. The government has determined that the Cummins ISL9 450 is the only engine capable of meeting the agency's needs due to the proprietary and integrated design of the E-One P-31 ladder truck chassis. The justification cites multiple technical barriers to competition, including OEM design integration where the engine bay, drivetrain, and support systems are factory-engineered specifically for the Cummins engine's dimensions and configuration; proprietary electronics and software that communicate exclusively between the vehicle's electronic control module and the Cummins engine's ECM; and voiding of critical safety certifications from the National Fire Protection Association and Department of Transportation if a non-OEM engine were substituted. The document notes that re-engineering costs for integrating an alternative engine would exceed the cost of the specified engine. The Contracting Officer, Donna Doss (90 CONS, contact (307)773-4741), determined on April 14, 2026 that anticipated costs will be fair and reasonable based on comparison with local vendor quotes and an Independent Government Cost Estimate. The justification acknowledges that future emergency vehicle acquisitions will consider requirements for non-proprietary, standardized, and interoperable components to promote competition.
