NIGP 59533: Grates, Guards, and Other Protective Devices for Trees and Shrubs

NIGP 59533 Grates, Guards, and Other Protective Devices for Trees and Shrubs, an Item code, covers products and services that protect or support landscape elements in public infrastructure—primarily manhole covers, drain grates, and related protective hardware used in municipal utilities and public works, though the code name itself suggests a narrower scope around arboricultural protection. State and local governments procure these items on standing requirements contracts with as-needed ordering, as protective equipment for subsurface utility access points. The issuing bodies are primarily county public works departments and municipal utilities; Pasco County Board of County Commissioners is an active repeat buyer in this space. Work is typically sourced through IFB and standing requirements vehicles with multi-year terms and price adjustment provisions indexed to the Consumer Price Index, reflecting the commodity nature of the category.

Recent activity clusters in Florida and Georgia. Pasco County Board of County Commissioners issued IFB-KM-26-068 in April 2026 for as-needed supply of composite manhole covers, grates, ring covers, and riveted steel grating, with delivery to county public works locations; the contract runs October 1, 2026, through September 20, 2029, with two optional one-year extensions under the same pricing, and local vendor preference applies within specified match thresholds. DeKalb County issued ITB 2026-076-ITB in June 2026 for reconstruction of the DeKalb Tennis Center in Mason Mill Park, Decatur, Georgia, with a response deadline of July 13, 2026; the scope included IT and low-voltage infrastructure installation with conduit, raceways, cabling, and terminations. The code also captures arboricultural protection: the City of Jackson, Michigan posted solicitation 2026ENGINEERING023 on July 14, 2026, for furnishing, planting, and maintaining approximately 200 street trees across 15 species for fall 2026 planting, with renewal options through spring 2028, prevailing wage compliance, and liquidated damages for delays.
