NIGP 54586: Trowler, Concrete, Engine Driven

NIGP 54586 Trowler, Concrete, Engine Driven is an Item code covering concrete surface preparation and finishing equipment used in small-scale municipal infrastructure and facilities work. State and local governments procure under this code primarily for sidewalk replacement, concrete resurfacing, and bridge or parking surface work where engine-driven power trowels are deployed to finish fresh concrete. The issuing bodies span city development authorities, county public works departments, and municipal infrastructure agencies managing routine concrete maintenance and emergency infrastructure repairs.

Recent activity shows the City of Madison Community Development Authority soliciting concrete sidewalk removal and replacement at Gay Braxton Apartments (due July 17, 2026), and Orange County, Florida issuing an emergency bid for full bridge replacement at two locations with an estimated project cost of $6,202,246.05 (due July 7, 2026). Both opportunities are conducted as sealed-bid procurements with electronic submission requirements. Madison's scope encompasses sawcutting and removal of approximately 1,300 square feet of existing concrete, subgrade preparation, gravel base installation, new concrete placement with 4,000 PSI minimum air-entrained concrete and 4-inch thickness, broom finish, ADA-compliant slopes, and erosion control—all typical applications where power trowels finish concrete surfaces to specification. Orange County's emergency bridge replacement projects are larger in scope and dollar value but similarly require concrete finishing work as part of the structural and surface work. Geographic activity concentrates in Wisconsin and Florida in the most recent postings, with cooperative purchasing vehicles like Sourcewell expanding reach across multiple states and jurisdiction types for standardized equipment contracting.
