- No HVAC or electrical system commissioning is required, but the systems must be tested, balanced, and have their controls verified.
- Wave guides may be needed for wall penetrations into the SKIFF area, which could impact the placement of the planned mini-split HVAC units.
- The base operates and maintains the existing control systems, with a local vendor as the installer.
- Duct-mate flanged construction is acceptable for sheet metal tie-ins on the new air handling units.
