NIGP 91344: Construction, Railroad

NIGP 91344 Construction, Railroad, is an Item code covering track inspections, maintenance, repairs, and specialized railroad infrastructure work that state and local governments solicit on an as-needed basis—from routine spur-track maintenance to complex bore operations under active railroad rights-of-way requiring operator coordination and specialized equipment. Recent solicitations show municipalities, counties, special districts, and regional authorities as the primary issuing bodies, with Texas, California, Florida, South Carolina, and Georgia representing the geographic breadth of current activity. The work spans routine preventive maintenance (City of Dallas's 36-month Indefinite Delivery/Indefinite Quantity track inspection agreement, RFP due November 13, 2026) through capital-intensive infrastructure projects (Greenwood Metropolitan District, South Carolina's railroad bore under CSX crossing requirements, IFB due October 27, 2026, with mandatory site visit on October 21, 2026 and 24-hour continuous jack-and-bore operations specified). Railroad protective liability insurance—$5 million per occurrence or higher—is a consistent requirement when work occurs on active rights-of-way, and performance bonds equal to 100 percent of contract value are standard.

Geographic concentration appears heaviest in California and Florida, where county transportation and utility districts regularly issue infrastructure rehabilitation work, but activity spans from the Southeast (South Carolina, Georgia) through the Southwest (Texas). Hillsborough County, Florida (ITB 26-00355 for railroad crossing dynamic envelope installation and maintenance over three years, bids due August 18, 2026, estimated value $635,500.00) and multiple Santa Clara County, California prequalification efforts for hospital seismic-compliance railroad-related components demonstrate repeat issuing-body engagement. The code sees both quick-turnaround sealed-bid work (Greenwood's 120-day substantial completion requirement) and longer-term service agreements structured as blanket purchase orders with unit-price adjustments. Contractor licensing, CSX or other railroad-operator clearance, and compliance with rail-crossing technical standards (FDOT, GDOT, California Administrative Code Chapter 6) are standard gate requirements; firms without active railroad authorization are ineligible.
