About NIGP 13550
NIGP 13550 Stone, Building (Except Marble) is an Item code that captures state and local procurement of dimension stone, aggregate materials, and rubble for infrastructure, construction, and grounds maintenance projects. Recent solicitations show governments buying crushed stone, gravel, granite rubble, cobble rock, graded base materials, and aggregate in specified sizes for road base, dike reinforcement, trail construction, and equipment delivery. The buying bodies include state departments (California CAL FIRE, Commonwealth of Massachusetts, State of Utah), counties (DeKalb County Georgia, Pasco County Florida, Williamson County Texas, Boulder County Colorado), cities (Brockton Massachusetts, Farmington Utah, Columbus Georgia, Plant City Florida, Upton town), and special districts (Washington Suburban Sanitary Commission Maryland). Most activity clusters around routine materials procurement through sealed bids and RFQs with response windows of two to four weeks.
Geographic concentration appears heaviest in the Southeast and West—California, Georgia, and Utah dominate recent postings—with secondary activity in Massachusetts and Colorado. Representative opportunities include the State of Utah Division of Purchasing's May 2026 IFB for 3,750 tons of 3–10 inch cobble rock delivery to Farmington Bay Wildlife Management Area (due June 8, 2026); DeKalb County Georgia's June 2026 ITB for granite rubble stone under a three-year multiyear contract (due June 17, 2026); Farmington City Utah's June 2026 sealed-bid solicitation for Lower Farmington Creek Trail construction including rock steps, stairways, and retaining walls (due July 16, 2026); and Columbus Consolidated Government's June 2026 RFB for mixed stone classifications and aggregates on an annual as-needed basis with award to two primary and secondary vendors (due June 17, 2026). Unit pricing, FOB or delivery terms, and two- to three-year contract periods are standard; most buyers require sealed bids submitted through county portals or e-procurement systems.
