NIGP 21072: Risers and Cones, Reinforced Concrete

NIGP 21072 Risers And Cones, Reinforced Concrete is an Item code representing cast-in-place and precast reinforced concrete structural elements for infrastructure applications. State and local governments procure these materials primarily for stormwater and sanitary sewer systems, utility support installations, and heavy-load-bearing applications in public works projects. Recent solicitations show demand across detention basins with concrete box structures, precast thrust blocks for pipeline systems, precast pads and sleeves for utility equipment (transformers, EV chargers), and concrete installations at municipal facilities. The issuing bodies span major cities (Houston, Tampa, Santa Cruz), counties (Santa Clara, Orange County, Sanitation District No. 2-3), and utility authorities (Kissimmee Utility Authority). Work consistently includes structural design compliance, dimensional accuracy requirements, and integration with ancillary infrastructure such as utilities, stormwater management, and traffic systems.

Recent activity concentrates in California, Florida, and Texas. The City of Houston posted a $75 million detention basin project (CSP20260011, RFP, response due November 5, 2026) encompassing 8-foot-6-inch reinforced concrete box structures and related infrastructure. Kissimmee Utility Authority issued a rebid for precast concrete pads, sleeves, and posts (AR 26-050-JG, ITB, due August 11, 2026) across 16 line items with 476 estimated units over five years. Santa Clara County Sanitation District No. 2-3 solicited bids for sewer rehabilitation including precast concrete sanitary sewer manholes (ITB-RDA-FY27-0088, due September 17, 2026). The City of Tampa requested quotes for 40 precast concrete thrust blocks (RFQ 26-P-00541, due September 22, 2026). Municipal concrete work also appears in pavement and sidewalk projects where reinforced concrete elements are secondary to larger scope. Prevailing wage and public-works compliance requirements are standard across jurisdictions, with bond and insurance documentation routinely required.
