Attachment 4 - Cascade Wind Tunnel (CWT) Photos.pdf

This document is a photographic record of the Cascade Wind Tunnel (CWT) removal project, containing 16 images documenting the facility's condition and components prior to decommissioning.

The photographs provide comprehensive visual documentation of the wind tunnel facility, including entrance hallway views, external structural elements of the main test chamber (front left side, corners, and walkways), internal components such as the middle section piping and ducting systems, interior test chamber views, and rear structural sections. Additional images detail the chiller unit (a Liebert model VH412WHAA0l with specifications including 460-volt, 3-phase, 60-hertz power requirements, serial number 693180-001, and R-22 refrigerant), its physical placement and connections to associated ductwork, and the building utility piping that requires capping. The documentation concludes with exit corridor views showing the facility's access points. The images collectively illustrate the scale, complexity, and interconnected systems of the CWT facility, including white composite structural panels, internal piping networks with yellow safety markings, test equipment with red and white coverings, control systems, and overhead ductwork arrangements. This photographic set appears designed to support the planning and execution of facility removal, demolition, or salvage operations by providing detailed visual reference of existing conditions and component locations.
