The U.S. Army Corps of Engineers (USACE), Los Angeles District, is conducting market research to identify prime contractors capable of the design-build replacement of the chiller and control system for the Vertical Wind Tunnel (VWT) at Yuma Proving Ground, Arizona. The anticipated scope of work includes developing a complete design for the new chilled water system, performing site work, procuring and installing new water-cooled chillers, and installing a new direct digital control system. The project has an estimated magnitude of construction between $1,000,000 and $5,000,000, and the anticipated period of performance is 365 days. • The project requires a design-build solution to replace an existing 450-ton chiller with a respective control system. • The new chiller system must provide reliable cooling performance under peak summer conditions and integrate with the VWT's main flight control system. • The project involves Controlled Unclassified Information (CUI) and may require compliance with Cybersecurity Maturity Model Certification (CMMC) Level 2. • The Government intends to specify a brand-name item, the iFLY / SkyVenture Tunnel Systems, for the Vertical Wind Tunnel Flight Control System.
