The Department of Defense, specifically the Marine Corps Installations - National Capital Region (MCI-NCR), intends to award a sole source contract to Environmental Systems Research Institute (ESRI), Inc. for the procurement of ESRI Arc Geographic Information System (GIS) mapping software and maintenance support. This acquisition is essential for the United States Training and Education Command, as the ArcGIS software is the authorized mapping tool within the Department of Defense and is uniquely compatible with the Range Managers Tool Kit (RMTK), which is critical for range management and safety protocols. The contract is valued at an undisclosed amount for the period from January 1, 2026, to December 31, 2026, and interested parties may submit capability statements to Michael Bogatyr at michael.bogatyr@usmc.mil for consideration, although this notice is not a request for competitive quotes.
