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 does not align with the recent state and local procurement activity tagged under it. The sole recent opportunity in the dataset—the City of Lavonia, Georgia's Water Treatment Plant 2026 Improvements project—involves comprehensive modifications to water treatment infrastructure, including upgrades to pump stations, mixers, settling basins, filtration units, chemical feed systems, and storage tanks. Rock bolts, which are mechanical anchoring devices used in underground mining, tunneling, and deep excavation work, do not appear in the scope of this water treatment facility upgrade. The mismatch suggests either a classification error in the opportunity posting or that this Commodity code sees minimal relevant activity in recent state and local procurement.

The Lavonia bid represents an IFB issued under sealed competitive bidding by a city-level jurisdiction, with a response deadline of May 26, 2026, and a pre-bid conference on May 7, 2026. The project is partially funded through the Georgia Environmental Finance Authority State Revolving Fund and subject to Davis-Bacon prevailing wage requirements and the Build America, Buy America Act. DBE participation goals of 4.0% for minority-owned and women-owned businesses apply. Beyond this single entry, the source provides no additional recent state and local opportunities tagged to the rock bolt code, no repeat issuing bodies, and no geographic pattern across multiple jurisdictions to characterize.
