Travis AFB intends to sole source the purchase of vertical carousels (megastations) from Advanced Office Systems, the only authorized retailer and servicer for the northern California region. The requirement is based on a letter of exclusivity from the original equipment manufacturer, Kardex, and using any other vendor would cause operational degradation. No budget amount or performance timeline is specified in this pre-solicitation notice. The location for performance of services is Travis Air Force Base, California. This notice indicates a non-competitive procurement opportunity for the designated sole source provider.
