JA_AAON Split DX AHU_Fully Signed_Redacted.pdf

This is a Justification and Approval (J&A) document for other than full and open competition, issued by the US Army Engineer District, Corps of Engineers in Louisville, KY for the AAON Split DX AHU with Condensing Natural Gas Furnace for an Indoor Small Arms Range project at Grissom Air Reserve Base (GARB), Indiana. The equipment will be included as a requirement for the construction contractor in a firm-fixed-price Design Bid Build construction contract funded with MILCON funds.

The J&A justifies sole-sourcing to AAON as the only vendor that can provide the required low-capacity DX HVAC units with condensing furnaces meeting the project's specific needs. The Indoor Small Arms Range requires 21 firing line positions and must meet DoD antiterrorism/force protection requirements. The AAON Split DX AHU was selected after LCCA evaluation as the only solution to minimize wall penetrations, reduce maintenance costs, and meet the 30% building energy reduction target. A Notice of Intent to Sole Source was posted on SAM.gov on August 19, 2024, with responses due by September 3, 2024. No responses have been received to date. The document includes certifications from the Project Architect, Project Manager, Contracting Officer, and Senior Assistant District Counsel approving the sole source justification.
