D--Intent to Award
Solicitation # 140G0126Q0188
The U.S. Geological Survey intends to award a sole source purchase order to EarthScope Consortium, Inc. for the long-term archiving, curation, and dissemination of continuous Global Navigation Satellite System data generated by USGS-supported monitoring stations, with a period of performance spanning from August 1, 2026, through June 30, 2031, including four one-year option periods. This action is justified under FAR 13.106-1(b)(1) due to EarthScope Consortium’s unique status as the sole nationally recognized, USGS-approved repository for GNSS data that meets the agency’s Fundamental Science Practices requirements for trusted, discipline-appropriate data management. EarthScope operates the GAGE geophysical data facilities, which already provide scalable, production-level infrastructure, standardized workflows, and metadata frameworks used by USGS and other federal and academic partners, eliminating the need for redundant or incompatible systems. The decision follows comprehensive market research that confirmed no other entity can provide equivalent services without prohibitive cost, delay, or fragmentation of data standards. The requirement includes routine annual archiving for active stations and a single ingestion of historical data from a legacy station, with all services delivered through an existing, certified cyberinfrastructure that ensures data integrity and broad accessibility. EarthScope’s established role as the primary national hub for GNSS data, its deep integration with USGS science operations, and its proven compliance with federal data governance policies make it the only viable source for this critical function. The contracting office has determined that competition would be impractical due to the specialized technical, scientific, and infrastructure requirements, and future competitions would only be considered if new repositories are formally recognized as meeting USGS FSP standards or if the agency develops an internally managed archive of equivalent capability. Questions regarding this intent to award must be submitted to the Contract Specialist by June 29, 2026, and the action will proceed under simplified acquisition procedures without soliciting competitive bids.
