NIGP 91377: Maintenance and Repair, Pipe Culvert

NIGP 91377 Maintenance and Repair, Pipe Culvert is an Item code covering the repair, rehabilitation, and replacement of culvert systems and drainage pipes serving state and local infrastructure. State and local governments procure under this code concrete and metal pipe rehabilitation (cured-in-place pipe lining, polyethylene slip lining, pipe bursting), box culvert and structural repairs, concrete pipe replacement, CCTV inspection and cleaning services, and full culvert replacement projects ranging from single-location work to multi-site statewide as-needed contracts. Recent solicitations show a mix of county engineering departments, municipal public works agencies, regional water authorities, and special districts as repeat buyers. County of San Mateo (California) issued a sealed IFB on July 17, 2026 for the Entrada Way Culvert Slip-Out Bank Stabilization Project with bids due July 23, 2026, covering 600 feet of creek stabilization and 24-inch storm drain pipe installation at an engineer's estimate of $2.249 million. Coffee County, Georgia released a sealed IFB on July 16, 2026 for Old Coffee Road culvert replacement (nine triple 6'×6'×34' culverts) with bids due July 31, 2026 and mandatory prequalification with the Georgia Department of Transportation.

Activity concentrates in Georgia, Florida, California, and Texas, with secondary participation from Oregon, Michigan, Massachusetts, and the Mountain West. Issuing bodies span county boards of commissioners, municipal public works and utilities departments, special districts (county water authorities, flood control districts), and state departments (MDOT, Oregon DOT). Prequalification requirements—state DOT prequalification, water main installation certifications, or gravity sewer contractor status—function as mandatory eligibility gates in many procurements.
