Limited Sources Justification for Esri ArcGIS Software Maintenance

NASA is issuing a Special Notice announcing a sole-source Limited Sources Justification for FY27 Esri ArcGIS software maintenance, with responses due November 23, 2026. The notice uses no set-aside and restricts the requirement to Esri, Inc., the original developer and manufacturer of the ArcGIS platform. The attached post-award justification covers software updates, security patches, bug fixes, version upgrades, license management, lifecycle support, and direct manufacturer technical assistance across all NASA centers. It states that NASA's integrated databases, custom applications, and asset-management systems are deeply embedded in the platform. It finds that Atlas, QGIS, Mapbox, Google Maps Platform, and Maptitude cannot provide Esri's proprietary access, licensing authority, or manufacturer-level resources. It also states that migration would require security recertification, ATO processes, data migration, and retraining, at a cost of tens of millions of dollars. The justification describes a firm-fixed renewal under GSA Federal Supply Schedule Contract GS-35F-253CA, with a period of performance of October 1, 2026 through September 30, 2027. Before contract execution, Esri will submit a quotation for evaluation and negotiation to establish fair and reasonable pricing.
