SF 1009 Sole Source Justification below SAT_DCF Heat Exchanger_Post_Redacted.pdf

This is a Department of Treasury SF 1009 Sole Source Justification form for an acquisition at or below the Simplified Acquisition Threshold. The requesting activity is the Bureau of Engraving and Printing, Office of Facilities Support, and the requisition number is 165842. The estimated IGCE dollar value is redacted in the document.

The procurement involves one RTB-6A-222x72 replacement tube bundle and one HXR-6A-20x116-04-AA shell-and-tube exchanger to be delivered to the Bureau of Engraving and Printing in Washington, DC. The selected vendor is Mainstream, Fluid and Air, LLC. The justification cites urgency as the basis for sole source procurement; the bureau's heat exchanger, which has been in continuous use since 1975 (approximately 32 years), has experienced major damage to its tubing that requires urgent repair. The damaged tubing prevents the HVAC system from operating efficiently, compromising cooling and heating to the bureau's manufacturing directorates and offices. Installation and repairs will be performed by a government-employed repairman from the Plumbing and Pipe Fitting Shop, with that shop assuming sole responsibility for maintenance and repairs following part installation. The contracting officer, Terry Lawrence, approved the justification on 06/26/2026, determining that the circumstances make only one brand-name or source reasonably available and preclude competition.
