NIGP 30578: Surveying Instruments and Accessories: Alidades, Compasses, Levels, Theodolites, Transits, Tripods, etc. (see 305-60 for Surveyor's Measuring Equipment)

NIGP 30578 Surveying Instruments and Accessories: Alidades, Compasses, Levels, Theodolites, Transits, Tripods, Etc. is an Item code that encompasses surveying hardware, software, and field instrumentation used by state and local governments for property boundary surveys, right-of-way determinations, topographic analyses, elevation certificate preparation, and CORS (Continuous Operating Reference Station) network operations. State and local jurisdictions—primarily county governments, state departments of transportation, and municipal public works and planning departments—solicit under this code for boundary and topographic survey work on a continuing-services or task-order basis, as well as for the purchase and maintenance of proprietary surveying equipment such as Trimble GPS and CORS systems. The scope spans both labor-intensive professional surveying services with qualifications-based selection and direct-purchase solicitations for physical survey markers and instrumentation or related software licenses and maintenance contracts. Issuing bodies include county property appraiser and engineering offices, state DOTs, city public works and planning departments, and special-purpose authorities.

Monroe County, Florida posted RFQ 649 on September 24, 2026, seeking qualifications for professional surveying continuing services with responses due October 27, 2026, under which the County anticipates retaining at least three qualified firms under four-year task-order contracts with hourly rates and per-project not-to-exceed caps (construction projects capped at $250,000; study activities capped at $25,000 in professional services fees). The Illinois Department of Transportation awarded a sole-source contract to Seiler Instrument for Trimble Survey-GPS equipment maintenance and repair across all nine Districts and the Central Office for Fiscal Year 2027 valued at $1,497,317.87, and separately published a sole-source change order notice (dated September 9, 2026) for Pivot Software and CORS Software supporting Trimble Network Managed Services valued at $1.23 million under existing contract P-80386. The City of Houston posted an informal solicitation (INF 20260382, due September 18, 2026) for survey point stake markers; full details were not accessible from the source material. Recent activity is concentrated in Florida, Illinois, and Texas.
