UNSPSC 72141109: Viaduct construction and repair service

The building and repair of viaducts owned by others

UNSPSC 72141109 Viaduct construction and repair service is a Commodity code under which state and local governments procure infrastructure work involving above-grade structures carrying roadways, utilities, or pedestrian facilities. Recent opportunities show that the code captures a mix of bridge and viaduct replacement, rehabilitation, and safety-system installation projects across counties, cities, and transit authorities. The code's scope extends beyond standalone viaduct work to encompass comprehensive construction and improvement of elevated infrastructure systems, including detection and signage equipment, pavement treatment, drainage integration, and utility coordination. Issuing bodies include county transportation departments (Santa Clara County, Maricopa County), city public works and infrastructure divisions (Tallahassee, Louisville Metro), water and transit authorities, and special districts. Representative recent work solicited ranges from Louisville Metro's Via-Smart viaduct safety project—a federal SMART grant-funded installation of over-height-vehicle and flood-detection systems at four Jefferson County viaducts, posted March 25, 2026, with bids due April 16, 2026 via IFB—to Santa Clara County's Expressway Guardrail Replacement and Safety Barrier Improvements project, posted March 25, 2026, with bids due April 23, 2026, involving removal and replacement of guardrails, barriers, and crash cushions on expressway segments.

Geographic activity concentrates in California (Santa Clara County), Florida (Tallahassee, Broward County), Georgia (DeKalb County), Kentucky (Louisville Metro), Colorado (Boulder County), and Texas (Cibolo, Broward County), with secondary activity in Arizona, Connecticut, and South Carolina. State and local buyers are treating viaduct and bridge infrastructure as critical capital priorities, particularly where flood resilience, vehicle-strike prevention, or utility coordination features prominently in the scope. Most opportunities require prequalification with state departments of transportation or local procurement systems, submission of performance and payment bonds in the 5–100 percent range, and compliance with prevailing wage, OSHA, environmental permitting, and minority/women business enterprise participation thresholds. Contract terms typically span 45–365 calendar days with liquidated damages ranging from $250 to $2,667 per day. The code shows steady activity suitable for firms with established bonding capacity, relevant bridge or elevated-infrastructure experience, utility and traffic coordination capability, and readiness to navigate multi-phase environmental and federal permitting requirements.
