UNSPSC 20101900: Secondary rock breaking systems

UNSPSC 20101900 Secondary rock breaking systems is a Class code that state and local governments use to tag material processing and aggregate preparation work, though the recent solicitation activity under this code shows little direct alignment with the code's nominal scope. The Maryland Environmental Service's competitive sealed bid for rock and material screening and sorting at the Harford Waste Disposal Center (due June 8, 2026) represents the only recent opportunity genuinely matching secondary rock breaking or aggregate processing. The remaining opportunities in the dataset—vertical conveyance system maintenance in Tucson, law enforcement equipment through Sourcewell, roadway capacity expansion and pavement rehabilitation in Broward County and Santa Clara County, CTE and Advanced Academics resources for Klein Independent School District, and guardrail replacement and bridge construction in Santa Clara County—are unrelated to rock breaking, material screening, or quarry operations and appear to have been tagged with this code in error. The code shows minimal recent activity among state and local buyers, and the single relevant opportunity (the Maryland Environmental Service solicitation) does not establish a pattern of regular or broad-based procurement demand.

The Maryland Environmental Service solicitation is the only recent state or local opportunity supporting pursuit under this code. The agency sought competitive sealed bids to screen, sort, and relocate approximately 130,000 cubic yards of blasted rock spoils from landfill cell construction into five material categories (rock greater than 18 inches, 12-18 inch Class II Rip Rap, 6-12 inch Class I Rip Rap, 4-6 inch gabion stone, and 1.5-4 inch stone) at the Harford Waste Disposal Center in Harford County, Maryland, with work commencing by July 1, 2026 and completion by December 31, 2026. The procurement was designated as a Small Business Reserve (SBR) award with a 15 percent Minority Business Enterprise (MBE) subcontract participation goal; electronic bids were due June 8, 2026. Bidders were required to submit pricing for three bid items based on estimated material volumes and to provide Contractor's Qualification Questionnaires, equipment lists, subcontractor lists, and required certifications. A pre-bid conference was held May 12, 2026, with site visits available May 12–22, 2026. Beyond this single Maryland Environmental Service opportunity, the code does not display sufficient recent state and local activity to characterize a pattern of demand or geographic concentration.
