NIGP 13550: Stone, Building (Except Marble)

NIGP 13550 Stone, Building (Except Marble), an Item code, encompasses aggregates and dimensional stone products that state and local governments procure for infrastructure maintenance, trail and park projects, and facility construction—ranging from crushed base and graded aggregate materials used in road and parking lot foundation work to granite rubble, cobble rock, and custom stone varieties for landscaping and erosion control. Recent solicitations show municipalities and counties purchasing stone on both routine annual supply contracts and project-specific bases, with issuing bodies including county parks departments, city public works offices, state transportation and forestry agencies, and municipal highway and capital improvement programs across a geographically dispersed market.

Activity under the code spans multiple states and issuing-body types. Bergen County, New Jersey Department of Parks posted a 24-month catalog contract for stone products in August 2026; Montgomery County, Pennsylvania Department of Assets & Infrastructure solicited prefabricated shelter installation work with faux brick exterior matching in August 2026; and the Town of Peru, Massachusetts Board of Selectmen requested dense grade products meeting MassDOT specifications via sealed bid in July 2026. The State of Utah Division of Purchasing sought 3,750 tons of cobble rock delivery to Farmington Bay Wildlife Management Area under an IFB in May 2026; DeKalb County, Georgia requested granite rubble stone on a three-year multiyear ITB basis in May 2026; and Columbus Consolidated Government awarded stone contracts to two primary and secondary vendors on an as-needed annual basis with optional renewal periods. Additional recent opportunities include the City of Brockton, Massachusetts Department of Public Works (crushed run gravel, June 2026), the Commonwealth of Massachusetts (crushed stone 3/4" and graded base material, May 2026), Boulder County Parks and Open Space Department (landscape and erosion control materials on a tiered short-list arrangement through May 2026), the Town of Dudley, Massachusetts (highway construction materials and services for FY27), and CAL FIRE Jackson Demonstration State Forest (1,500 tons of 1-inch crushed base rock delivery, May 2026). Sourcing remains active in the Northeast, Mid-Atlantic, and Western states, with repeat purchasing through annual and multiyear term contracts as the dominant acquisition vehicle.
