NIGP 91071: Shoring and Reinforcement Services

NIGP 91071 Shoring and Reinforcement Services, an Item code, encompasses labor, materials, and permitting for retaining walls, slope reinforcement, revetment systems, and erosion control infrastructure that state and local governments procure to stabilize embankments, restore drainage assets after weather events, and prevent site degradation. Recent solicitations show Florida state agencies and municipalities issuing ITBs and IFBs for rock gabion walls, articulating concrete block and rip-rap revetment with geotextile reinforcement, and sheet pile systems designed to meet geotechnical specifications and aesthetic preservation objectives. The Florida Department of Environmental Protection, Bureau of Design and Construction, and the City of Casselberry emerge as active buyers, with the City of Casselberry recently posting a post-hurricane erosion repair project totaling $623,345 across two locations. Issuing bodies include state environmental protection departments and city engineering offices, typically bundling shoring and reinforcement work with related site restoration, drainage reconstruction, and permits.

Florida dominates the recent activity. The Florida Department of Environmental Protection issued an IFB (BDC05-26-27) for the Madison Blue Spring Retaining Wall project with bids due October 6, 2026, specifying rock gabion wall design and requiring bidder prequalification or current state contractor licensing; Addendum No. 1, posted September 29, 2026, clarified that precast concrete substitution would not be accepted without additional engineering analysis. The City of Casselberry posted ITB 2026-1468 for the Gee Creek Erosion Control Projects on September 21, 2026, with bids due August 25, 2026 (note: the source contains a date discrepancy; the ITB posted after the stated due date), requiring five years' prior experience in similar work, geotechnical-informed slope stability design, a mandatory pre-bid conference on August 4, 2026, and substantial completion within 70 consecutive calendar days with liquidated damages of $1,609 per day. The project includes sediment removal, slope revetment and reinforcement, concrete flume construction, and site restoration at two municipal locations, with partial NRCS funding and federal procurement compliance obligations.
