NIGP 91115: C.i.p., Construction/Rehabilitation, Other Than Buildings

NIGP 91115 C.i.p., Construction/Rehabilitation, Other Than Buildings is an Item code encompassing infrastructure repair, replacement, and rehabilitation work across water systems, wastewater conveyance, transportation corridors, drainage systems, utility relocation, and associated site restoration. State and local governments solicit under this code for structural rehabilitation of aging utility assets, new utility main installations, bridge repair and replacement, parking and drainage improvements, and emergency reconstruction following natural disasters. Work ranges from confined-scope pipe replacement and tank rehabilitation through multi-phase corridor improvements spanning miles of infrastructure.

Recent activity clusters in Florida (Orange County, Volusia County, Collier County), Georgia (Gwinnett County, DeKalb County, Lowndes County), and Texas (Houston, Amarillo, Lawrenceville, Lubbock, Cibolo, College Station), with additional procurement from Pennsylvania, Connecticut, Michigan, California, Kentucky, and Colorado. Issuing bodies include municipal utilities departments, county water and transportation authorities, special districts, and city public works divisions. Representative solicitations include the City of Houston's rehabilitation of water storage tanks across four facilities (IFB, bids due August 20, 2026); Gwinnett County's State Route 120 Water Main Replacement requiring approximately 9,700 linear feet of 16-inch DIP installation (IFB, bids due September 4, 2026, with mandatory pre-qualification in subsection 2, Medium); Orange County Florida's emergency bridge replacement at Wallington Drive and Egret Way (IFB, bids due July 7, 2026, estimated $6.2 million); and City of Bradenton's Love Park construction encompassing site grading, playground equipment, landscape and irrigation, and ADA compliance (IFB, bids due August 13, 2026). Pre-bid conferences, mandatory pre-qualification programs, site visits, and question windows are standard. Construction Manager-at-Risk procurements for utility plant upgrades (Texas Facilities Commission, Texas School for the Deaf Central Plant Renovation) and design-build selections for parking facilities (Greater Orlando Aviation Authority) signal willingness to use alternative delivery methods on substantial projects. Collier County and other Florida jurisdictions repeatedly post construction engineering and inspection (CEI) services solicitations, typically allocating 10–12 percent of construction cost to oversight. Prevailing wage, performance and payment bonds, insurance minimums of $1–2 million commercial general liability, and E-Verify compliance are consistent requirements. FEMA-funded disaster reconstruction work (Volusia County beach access ramps, New Smyrna Beach police boathouse) carries federal compliance burden including Davis-Bacon Act wage schedules and domestic-material preferences.
