The Naval Surface Warfare Center Crane requires an annual maintenance agreement for VarioMill and VarioMetric equipment. This is a sole-source procurement intended for VarioScale, Inc., due to its ownership of proprietary data, schematics, trained personnel, and necessary parts. The performance location is not specified in the provided description. While the government intends to negotiate with one source, it will consider capability statements from other responsible sources for the purpose of potentially conducting a competitive procurement. All contractors must be registered in the System for Award Management (SAM).
