NIGP 15505: Barriers and Enclosures, Construction

NIGP 15505 Barriers and Enclosures, Construction is an Item code describing the construction and installation of permanent or temporary structural barriers, enclosures, and containment systems that state and local governments procure for site security, traffic management, environmental control, and facility protection. Recent solicitations show municipalities and special-purpose districts buying detention basin construction with reinforced concrete box structures, dumpster enclosures with masonry and metal components, fence replacement with aluminum rail systems, and traffic management equipment for supply and deployment at multiple locations.

State and local issuing bodies soliciting under this code include city procurement offices (Houston, Marietta, Brownsville, Rio Rancho, Tucson, Cibolo), county governments and boards of commissioners (Collin County, Dallas County, White County, Pinal County, Montgomery County, Hancock County Port & Harbor Commission, Harris County Flood Control District), school districts (Wilcox County Schools, Stephens County Board of Education, Jenkins County Board of Education), transit and special-purpose authorities (Charlotte Area Transit System, Tualatin Valley Fire & Rescue, Port Authority of New York and New Jersey, Atlanta Beltline Inc.), and water authorities (Macon Water Authority, City of Arlington). Recent opportunities cluster in Texas, Georgia, Florida, and Oregon. Representative recent solicitations include the City of Houston's $75 million TIRZ 17 Memorial City Area Detention Basin RFP (CSP20260011, due November 5, 2026) for underground cast-in-place concrete detention with reinforced concrete box structures and traffic infrastructure upgrades; the City of Marietta's design-build RFP for a dumpster enclosure with concrete masonry units and metal gates (PE63363NONST2027000000032, due October 22, 2026); the City of Acworth's IFB for 1,600 linear feet of aluminum 3-rail cemetery fence replacement (PE63350NONST2027000000036, due September 16, 2026); and the Port Authority of New York and New Jersey's two-year requirements contract for traffic management equipment supply and rental (BID6000003497, due October 19, 2026). Work spans detention and stormwater infrastructure, utility protection and relocation encasement, security barriers for corrections facilities and public venues, dumpster and waste containment enclosures, fence and gate systems, and specialized infrastructure installations such as drone docking stations. Activity remains steady across municipal capital improvement, facility rehabilitation, and emergency-response projects, with federal funding (FEMA Hazard Mitigation Grant Program, FDOT) present in multiple procurements and prevailing wage and compliance requirements common.
