UNSPSC 20101800: Mechanized ground support systems

UNSPSC 20101800 Mechanized ground support systems (Class) covers road construction, pavement rehabilitation, and utility relocation work that state and local transportation agencies, county governments, and cities solicit from qualified contractors. The code encompasses concrete and asphalt paving, curb and gutter installation, stormwater and sanitary sewer systems, water main and gas line relocation, erosion control, grading, traffic control devices, and roadway safety features such as guardrails and bioretention basins. Recent solicitations show active procurement across multiple issuing bodies, including city public works departments, county transportation authorities, and regional transit or infrastructure agencies. Scope typically requires general contractors and subcontractors to comply with state department of transportation standards, maintain performance and payment bonds at 100–210 percent of contract value, and meet prevailing wage, insurance, and safety requirements.

Recent activity concentrates in California and Georgia. The City of Marietta, Georgia issued an IFB (RFB 26-53444) due June 26, 2026 for roundabout construction at New Hope Road and Wylie Road, requiring GDOT certification and Georgia presence with a mandatory pre-bid conference on June 10, 2026 and 365-day completion window. Santa Clara County, California issued an ITB (ITBRDAFY260694) due May 21, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, encompassing partial depth recycling, hot mix asphalt overlay, PCC curb and sidewalk replacement, ADA improvements, bioretention basins, and traffic signal modifications with a 142 working-day completion timeline. A Sourcewell cooperative purchasing RFP (#061626) posted May 12, 2026 and due June 16, 2026 targets law enforcement equipment across multiple Washington counties and participating entities nationwide, though this opportunity appears unrelated to the road construction and pavement rehabilitation focus of the code itself.
