earthquake and volcano monitoring systems

The U.S. Geological Survey (USGS) is soliciting proposals for earthquake and volcano monitoring systems, including broadband seismometers, strong-motion sensors, data acquisition units (DAUs), accelerometers, and associated software and accessories to support the Advanced National Seismic System (ANSS), Global Seismographic Network (GSN), and USGS Volcano Program. The USGS emphasizes that the most critical specification is "Maximum Incoherent Noise" for broadband sensors rated "A+" according to the TestingSpecs2026 spreadsheet, as the GSN operates at seismically quiet sites requiring sensors with the lowest self-noise possible. Proposals will be evaluated based on five factors in declining order of importance: Technical Proposal, Equipment Testing, Past Performance, Subcontracting Plan, and Price, with award going to the responsible offeror offering the best value. Key requirements include submission of firm fixed-price proposals with pricing for all equipment categories over five years, technical specifications demonstrating compliance with TestingSpecs2026, documentation of at least three recent relevant contracts with references, and three sample units of any untested equipment delivered to the Albuquerque Seismological Laboratory (ASL) within 30 days of proposal submission. Proposals are due by May 29, 2026 at 15:00 PST, and all amendments must be acknowledged prior to submission, with the most recent amendment issued on April 9, 2026 providing technical references for testing methodologies.

This solicitation is designated for Women-Owned Small Business (WOSB) concerns, though the Government reserves the right to make multiple awards if deemed beneficial. The contract is structured as a single-award Indefinite Delivery/Indefinite Quantity (ID/IQ) agreement with an estimated five-year ordering period from August 16, 2026 through August 15, 2031, with a contract maximum of $30,000,000 and an initial order of at least $50,000 concurrent with award. Equipment must be new only, with no grey market or refurbished products accepted, and all equipment must be covered by manufacturer's warranty. Proposals must not exceed 50 one-sided pages in 12-point font and should be submitted electronically to thuot@usgs.gov in two separate PDF volumes—one for Technical Proposal and Past Performance documentation and one for pricing. The NAICS classification is 334513 (Instruments and Related Products Manufacturing) with a small business size standard of 750 employees, and no specific place of performance is designated, though equipment testing will occur at ASL with return of tested equipment to the contractor within six months.
