RFQ Lateral Move Irrigation System

The USDA Agricultural Research Service in Kimberly, Idaho, is requesting quotes for a lateral move sprinkler irrigation system with variable rate irrigation (VRI) controls under a Total Small Business Set-Aside, with quotes due June 26, 2026. This is a federally funded procurement restricted to small businesses under NAICS code 237110 (Water and Sewer Line and Related Structures Construction).

The primary scope covers design and installation of a hose-feed, electric-cord lateral move system on a 20-acre field (approximately 660 feet wide by 1,300 feet long, with maximum travel distance of 1,300 feet) comprising four equal-length spans. The system must include pressurized water supply from an existing 8-inch buried mainline, three-phase 480 VAC power from an irrigation pump located 480 feet south and 680 feet west of the southwest corner, sprinklers spaced at 30 to 40 inches, and variable rate controls at 80 to 110-inch spacing. Equipment specifications include Nelson Irrigation 15 psi pressure regulators, olive plate rotator sprinklers, GPS-guided controls with water-controlled solenoid valves, buried 125 psi PVC water supply risers (5-inch diameter soft hose connections), SOOW electrical cord, electrical pedestals with both 480V three-phase and 110V single-phase outlets, and remote monitoring and control via computer or smartphone. The VRI control system must support multiple stopping points and up to 10 sequential speed changes; maximum lateral travel speed is 9 to 12 feet per minute at 100% timer setting. An option is included for an identical second VRI lateral move system on an adjacent field (Field 2), with water supply available from either an extended pipeline from Field 1 or an existing 10-inch buried mainline. Contractors must verify all actual field distances during site assessment prior to design and installation. No contract value is stated.
