UNSPSC 31161632: Rock bolt

A bolt used to support and reinforce rock for mine shaft, tunnel, underground utility pipe conduit, cutting sloping side. It is placed by drilling a hole in the rock rocks around the mine shaft and tunnel and placing the bolt on the holes.

UNSPSC 31161632 Rock bolt is a Commodity code that covers fastening hardware used in underground construction and stabilization work, though recent state and local solicitation activity under this code shows limited direct alignment with the nominal scope. The water treatment plant improvements solicitation from the City of Lavonia, Georgia, and the butterfly valve RFQ from the Eastern Municipal Water District in California represent the recent activity tagged to this code, but neither procurement involves rock bolts as a primary deliverable—the Lavonia project encompasses comprehensive water treatment facility upgrades including mixers, settling basins, filtration units, and chemical feed systems, while the EMWD RFQ seeks specialized butterfly valve hardware. State and local buyers under this code span municipal utilities and public works departments, though the recent record is too limited to characterize a clear issuing-body mix or repeat buyers.

Activity under the code appears light across recent state and local procurement. The City of Lavonia posted sealed competitive bid PE66940NONST2026000000005 for Water Treatment Plant 2026 Improvements with a response deadline of May 26, 2026, and a pre-bid conference on May 7, 2026, requiring Georgia Utility Contractor licensure and Davis-Bacon prevailing wage compliance with 4.0% DBE participation goals. The Eastern Municipal Water District in Riverside County, California, issued RFQ 3930 for Lineseal XP 36" Butterfly Valves (Class 250B) with a quote deadline of March 20, 2026, and F.O.B. Destination delivery to the EMWD Operations and Maintenance Center Warehouse in Perris. Geographic reach touches Georgia and California, but the code shows no clear pattern of recent rock bolt procurement activity among state and local buyers.
