The Naval Air Warfare Center intends to sole source a 3-year renewal for M4 Software Maintenance to VertiGIS, LLC. While this is a non-competitive procurement, any firm believing it can fulfill the requirement may submit a capability statement via email for agency consideration within 5 days of the notice's publication. The work is associated with the China Lake, CA location. All contractors must maintain an active SAM registration, which now requires a notarized letter, and must be certified through Defense Logistics Information Services (DLIS) to access Controlled Unclassified Information.
