NIGP 91358: Construction, Viaduct (Includes Reconstruction)

NIGP 91358 Construction, Viaduct (Includes Reconstruction) is an Item code describing state and local procurement of drainage and stormwater infrastructure improvements, erosion repairs, utility relocations, and related infrastructure reconstruction or rehabilitation work — not solely bridge or viaduct work despite the code name. Recent solicitations show municipalities, counties, and special districts buying site-grading, pipe replacement, lift stations, trail construction, and concrete improvements alongside traditional viaduct and bridge work. The City of DeBary, Florida solicited comprehensive stormwater improvements (drainage systems, curb inlets, manhole structures, trench drains) in an IFB format for approximately $233,250; the Central Florida Tourism Oversight District sought S-40 erosion repairs including steel sheet pile installation and slope stabilization via ITB; and Santa Clara County issued sealed bids for pavement rehabilitation and stormwater infrastructure work. Issuing bodies span municipal public works departments, county transportation and drainage districts, water authorities, special independent authorities (Atlanta Beltline, Georgia World Congress Center Authority), and regional medical centers performing facility infrastructure upgrades. Counties and cities dominate the recent-opportunities block, with Santa Clara County, Orange County, and Pasco County appearing multiple times.

Recent activity concentrates in Florida (DeBary, Orange County, Pasco County, Broward County), California (Santa Clara County, coastal municipalities), Georgia (Columbus, DeKalb County, Henry County), and Arizona, with additional scattered opportunities in Kentucky, Texas, and Utah. Representative recent work includes the City of DeBary's Small Scale Stormwater Improvement Project No. 4 (ITB, August 2018 due date, $233,250 estimated cost) covering reinforced concrete pipe drainage, curb inlets, and concrete driveways; Orange County's emergency bridge replacement projects (sealed bids, estimated $6.2 million and $7 million respectively, posted June 2026); and Pasco County's Runnel Drive drainage improvements (IFB, June 2026 due, approximately $1.3 million per addendum). Federal compliance overlays—Davis-Bacon prevailing wage, CDBG funding requirements, Buy America provisions, and environmental permits—appear in transportation and infrastructure work. Liquidated damages, performance and payment bonds, and insurance minimums ($1–$5 million general liability per occurrence) are standard contractual features. Local vendor preferences exist in several jurisdictions; DBE participation goals of 10 percent appear in recent Georgia and Georgia-adjacent opportunities.
