NIGP 31870: Testing/Verifying Equipment

NIGP 31870 Testing/Verifying Equipment, an Item code, covers laboratory and field instruments used by state and local governments to measure, analyze, and validate the performance of systems, materials, and environmental conditions. Recent solicitations show state and local agencies purchasing spectrophotometers for wastewater treatment operations, underground and aboveground storage tank testing equipment, and geophysical and video logging services for water well construction—work ranging from direct equipment replacement to complex regulatory compliance testing across infrastructure and environmental programs.

Cities and special-purpose districts dominate activity under this code. The City of Tampa's Solid Waste & Environmental Program Management issued an RFQ for a Heck DR4900 Spectrophotometer (26P00372) with a response date of June 12, 2026, to replace an existing unit at the McKay Bay Waste to Energy facility. The City of Albuquerque's General Services Department Fleet Division posted an RFB (RFB2026761GSDID) due May 28, 2026, for maintenance, testing, repair, and installation services for underground and aboveground storage tanks at twelve fuel sites and three emergency generator sites across the municipality. The City of Palm Bay, Florida issued an RFP (30RFP26) due April 28, 2026, for design and construction of four production wells at the North Regional Water Treatment Plant, requiring step-drawdown testing, 8-hour constant rate discharge testing, geophysical logging with caliper, gamma ray, spontaneous potential, resistivity, acoustic, flow, fluid conductivity, and temperature sensors, and color video logging. Recent activity spans Florida, Texas, New Mexico, and other jurisdictions, with municipal infrastructure and solid waste operations as the primary drivers. Klein Independent School District in Harris County, Texas issued an RFP (#26-101) due June 5, 2026, for instructional resources and equipment across career technical education and advanced academics programs, a broader procurement category that may include testing equipment for science and technology labs.
