UNSPSC 73152121: Machine maintenance and alignment services

Machine maintenance is the means by which mechanical assets in a facility are kept in working order. Machinery maintenance involves regular servicing of equipment, routine checks, repair work, and replacement of worn or nonfunctional parts. Alignment the act of aligning or state of being aligned especially: the proper positioning or state of adjustment of parts (as of a mechanical or electronic device) in relation to each other.

UNSPSC 73152121 Machine maintenance and alignment services is a Commodity code encompassing preventive and corrective maintenance, repair, rebuild, and overhaul work on transit buses, municipal fleet vehicles, and heavy equipment. State and local governments soliciting under this code are purchasing on-site technician services for fleet maintenance, engine and chassis system repairs, tire services, hydraulic and drivetrain work, and mid-life repower overhauls. Issuing bodies include transit authorities (Broward County Transportation Department, Jacksonville Transportation Authority, City of Albuquerque Transit Department), municipal fleet management departments (City of St. Cloud, City of Daytona Beach, Collier County), and county departments managing diverse equipment inventories (Seminole County). These solicitations typically establish vendor pools or open-end indefinite quantity contracts allowing as-needed service delivery rather than single fixed-scope awards. Vendors regularly must demonstrate three or more years of relevant experience, hold state motor vehicle repair licenses or manufacturer certifications (Cummins, Voith, Allison, ZF for transmission work), maintain Florida Department of Agriculture & Consumer Services Motor Vehicle Repair Shop Registration where applicable, and carry substantial insurance including general liability, workers' compensation, and garage keepers' liability coverage. Many solicitations include federal compliance requirements tied to Federal Transit Administration funding, including Buy America certifications, Davis-Bacon prevailing wage compliance, and DBE participation goals.
