S -- - NOTICE OF INTENT TO NEGOTIATE A SOLE SOURCE CONTRACT WITH PATTEN ENGINEERING FOR A PASSIVE INTEGRATED TRANSPONDER (PIT) TAG INTERROGATION SYSTEM. Notice of intent to negotiate a sole source contract with Patten Engineering to design, construct, and evaluate a "flat-plate" style 134.2 kHz passive integrated transponder (PIT) tag interrogation system. System must 1) be designed to read 12mm x 2.1mm dia. International Standards Organization (ISO) based PIT tags at a vertical distance from an antenna 12" through water at a tag velocity of 3ms/s, 2) possess 4 antennas no greater than 4' x 2' x 4", each contained in its own watertight housing, and 3) each antenna must have its own tag recovery circuitry. Tag code recovery circuit must decipher tag codes up to the point of detection and digitizing into a TTL compatible signal. Patten Engineering recognized expert in field of radio frequency (RF) passive integrated transponder (PIT) tag systems since its owner developed implantable PIT tag and tag interrogation system for use in fisheries applications. Patten developed system currently deployed in the Columbia River Basin. Sources responding to this notice must indicate qualifications and experience in developing and deploying radio frequency passive integrated transponder tag systems in requests for this solicitation. Simple requests for the solicitation will not be honored. Direct requests for solicitation WASC8-494 to Randall Brown at 206-526-6226 or fax 206-526-6025. This is a simplified acquisition with an estimated value of less than $100,000.
