AI Contract Overview
The Nevada National Security Site and its affiliated facilities, operated by Mission Support and Test Services, LLC under the U.S. Department of Energy, are seeking a single-vendor solution to modernize their entire legacy landline telecommunications infrastructure. This effort encompasses six major locations including the NNSS, North Las Vegas Facility, Remote Sensing Labs in Maryland and Nevada, Special Technologies Lab in California, and operations in Livermore and Los Alamos, collectively handling over 1.5 million calls annually and supporting more than 25,000 direct inward dial numbers. The contract requires the replacement of traditional circuits with modern, high-reliability transport technologies such as fiber, Ethernet, and SIP, delivered through a unified vendor platform that manages all ordering, billing, support, and service level agreements. The solution must include on-premises equipment like routers and session border controllers, with T1/PRI final handoff, full DID and toll-free number support, local and long-distance dialing, faxing capabilities, and compatibility with General Dynamics vIPer phones in secure mode. A critical requirement is the provision of a POTS replacement solution that ensures uninterrupted 24x7 operations while enabling local site survivability in the absence of public access circuits at the NNSS. The contractor must provide web-based tools for real-time status monitoring, automated or manual call redirection, spam and auto-dialed call blocking, and robust 911 emergency calling functionality with accurate location identification. Billing must be structured and itemized by location to enable clear cost allocation across multiple sites. All support functions must be based in the United States and performed by U.S. citizens. Offerors are required to demonstrate proven capability through past performance records, including any Notices of Violation, and must be registered in SAM.gov with a valid Unique Entity Identifier. Responses must confirm company size under NAICS code 517810 and include a capability statement or relevant documentation, with submissions due by May 15, 2026. Participation in this sources sought notice does not obligate MSTS to enter into any contract or provide compensation, and offers are evaluated solely at the discretion of the agency for potential future award considerations.
