The National Institute of Standards and Technology (NIST) has announced its intention to negotiate a sole-source contract with Environmental Systems Research Institute Inc. (ESRI) for the procurement of ArcGIS software licenses and maintenance. This decision arises from the need for software compatibility with existing ESRI systems used by NIST's Engineering Laboratory. The specifications outline several licenses and subscriptions necessary for ongoing operations, all set to be effective from July 24, 2025, to July 23, 2026. The determination of a sole source is based on market research that identifies ESRI as the only provider capable of fulfilling NIST’s requirements. Interested parties who believe they can meet these needs are invited to respond by June 10, 2025, while all inquiries must be directed to a specified NIST representative. This notice serves as a precursor to a possible competitive procurement process, depending on any expressions of interest from other vendors.
