NIGP 91227: Construction, Irrigation System

NIGP 91227 Construction, Irrigation System (Item) encompasses installation and upgrade of irrigation infrastructure on public properties — wells, mainline pipes, control systems, landscape irrigation, and associated civil works serving agricultural, park, recreational, and municipal facilities. State and local governments use this code to procure comprehensive irrigation projects including site assessment, permitting, drilling, piping installation, equipment supply, and landscape restoration, often bundled with stormwater management, drainage improvements, or green infrastructure components. Recent solicitations show county parks departments, municipalities, water authorities, colleges, and special districts issuing RFPs, RFQs, IFBs, and ITBs for work ranging from $350,000 stock water well installations to multimillion-dollar campus-wide system replacements.

Issuing bodies span county parks and open space departments, city public services and utilities divisions, regional water authorities, public colleges, transit facilities, and state departments of water resources. Boulder County Parks and Open Space, Valencia College, the City of West Jordan, Orange County Florida, and Clackamas County appear as recent active buyers. Geographic activity concentrates in Florida (Orange County, Marion County, Brevard County drainage and irrigation work), Colorado (agricultural well development), Texas (landscape and irrigation improvements across multiple municipalities and water districts), Georgia (park and athletic facility irrigation), California (college campus upgrades, state water resources projects), Oregon (golf course systems), Arizona (sports facility irrigation), and Utah (streetscape irrigation). Recent representative opportunities include Boulder County Parks issuing RFP-300-26 for stock water well development on two agricultural leases by September 4, 2026 at $350,000; Valencia College issuing ITB 2026-23 for HDPE irrigation mainline replacements across three campuses with approximately 43,787 linear feet of pipe; City of West Jordan issuing IFB for irrigation installation and tree replacement at 4800 West by May 26, 2026; Clackamas County issuing sealed bids for Stone Creek Golf Club irrigation replacement (June 2, 2026) with engineer's estimate of $3 million to $5 million; and City of Lubbock issuing RFP 26-19455-KM for North Overton Tax Increment Finance Districts irrigation improvements with $400,000 estimated budget and 90-day completion window. Pre-bid meetings, site visits, and Q&A cycles are routine; electronic submission through county or city e-procurement portals or platforms such as Bonfire, OpenGov, and Bonfire Hub is now standard. Performance and payment bonds at 100 percent of contract value typically required; prevailing wage applies to Davis-Bacon-funded projects; local and small-business preferences appear in select jurisdictions.
