NIGP 96834: Dredging Services

NIGP 96834 Dredging Services is an Item code covering sediment and sludge removal from waterways, stormwater infrastructure, and treatment facilities through hydraulic, mechanical, and debris-clearance methods. State and local governments procure under this code to restore waterway capacity, improve water quality and stormwater function, comply with environmental permits, and address post-disaster erosion and sedimentation. Recent solicitations show Florida counties and cities (Brevard, Sarasota, Collier, Orange, Pinellas, and Seminole) dominating activity, with Georgia counties (Fayette, Liberty, Rockdale, Atkinson, DeKalb) and Texas Brazoria County also active. Issuing bodies span county natural resources departments, municipal stormwater and public works agencies, airport authorities, school districts, and water treatment plants. The Brevard County Sykes Creek Phase II project exemplifies large-scale activity: a $3.5+ million hydraulic dredging contract covering approximately 223,600 cubic yards in base bid (with optional zones totaling 128,800 additional cubic yards) including dewatering facility design, environmental permitting (USACE, FDEP, manatee and sea-turtle protection), and 1,400 calendar days to substantial completion under an ITB issued September 28, 2026.

Recent opportunities span multiple service types within the code. The City of Orlando's RFP 260204 (posted October 8, 2026) seeks as-needed hydraulic dredging services across multiple lakes with Davis-Bacon prevailing-wage compliance. The Greater Orlando Aviation Authority IFB 26-995-IFB (October 5, 2026) targets stormwater pond sediment removal at an airport with 41,500 cubic yards base bid, FAA security compliance, and a 2 percent combined Local Developing Business and Veteran Business Enterprise set-aside goal. Smaller-scope work appears regularly: the City of Casselberry ITB 2026-1468 (September 21, 2026) addresses post-hurricane erosion control with sediment removal and revetment installation at two park locations, budgeted at $623,345. Pinellas County School District RFQ 26HO032 (August 20, 2026) solicited ongoing retention-pond and ditch maintenance across multiple school sites. Water-treatment-plant lagoon dredging projects are active in Georgia—the City of Hartwell and Atkinson County both posted alum-sludge removal solicitations in June and July 2026. Geographic concentration is strongest in Florida's Gulf Coast counties and Georgia's mid-state region, with isolated activity in Texas (Brazoria County debris removal following Hurricane Beryl) and Mississippi. Davis-Bacon wage requirements apply when federal funding or disaster recovery grants are present. Performance bonds at 100 percent contract value, comprehensive general liability insurance ($1 million to $5 million per occurrence depending on project scale), and pollution liability coverage are standard requirements. Mobilization and dewatering-facility design responsibility typically falls to contractors, as does environmental permitting and compliance documentation.
