in-house gamma-counting system

The U.S. Geological Survey Pacific Coastal and Marine Science Center seeks quotations for a complete, in-house gamma-counting system, with quotations due August 24, 2026, at 5:00 PM Pacific Daylight Time. This is an open competition FAR 12 procurement for commercial products and services under NAICS 334516, Analytical Laboratory Instrument Manufacturing, with a size standard of 1,000 employees.

Delivery is to the PCMSC Marine Operations Facility in Santa Cruz, California, with an expected delivery date of August 24, 2026. The system must be new, non-portable, and configured for the facility's existing lab space, compatible with in-house 15-mm outer-diameter, 10-ml volume sample vials. Required components include a high-purity germanium well detector (1.4 keV FWHM at 122 keV and 2.3 keV FWHM at 1.33 MeV), a low-background J-type cryostat, a 25-liter cryogenic liquid nitrogen recycler with two-year warranty, a low-background lead shield with 4-inch-thick walls, a digital multi-channel analyzer with Ethernet or USB communication, and three specialized software applications (MCA emulation, detector efficiency transfer, and gamma analysis productivity software). Software must be compatible with Windows 11 and approved by the Department of the Interior for networked federal systems.

The RFQ includes three contract line items: gamma counting system, extended warranty through September 30, 2027, and installation and training services (October 1, 2026, through January 1, 2027). The vendor must provide four days of on-site installation, configuration, software setup, quality assurance testing, and user training, plus a single two-day post-installation technical support visit. Extended warranties must cover labor, materials, and return shipping for five additional years. All items must be brand new; used or refactored items are not acceptable. Vendors must register in SAM and provide their UEI number; quotations must be firm, fixed-price in U.S. dollars with FOB shipping to the delivery site. Evaluation factors include corporate experience and key personnel capability (weighted more heavily when combined), technical capability and capacity, past performance with at least three references, and price. Period of performance is 12 months from award date and may be extended for unforeseeable delays. The contracting officer is Tracy Huot (916-278-9330, tracy_huot@ios.doi.gov).
