Y1DA--CON 668-21-100 Upgrade AHUs 18-20-22 Mechanical Systems

The Department of Veterans Affairs is seeking proposals for mechanical system upgrades at the Mann-Grandstaff VA Medical Center in Spokane, Washington.

Technical requirements focus on hospital continuity through phased work and temporary equipment. A temporary air handler is required for AHU-18, and infection control barriers must be maintained. Work may need to occur after hours or on weekends to minimize noise.

Contractors must provide a temporary air handling system for AHU-18 to maintain operations. Phasing is required because of limited space for patient relocation. While the VA moves users, the contractor moves furnishings within the work area. Standard hours are 0700 to 1600, but noise-sensitive work may require evening or weekend c…
