UNSPSC 95121621: Seawall

A form of coastal defense constructed on the inland part of a coast to reduce the effects of strong waves.

UNSPSC 95121621 Seawall, a Commodity code, encompasses the design, construction, repair, and reinforcement of waterfront seawall structures that state and local governments procure to protect shorelines, manage erosion, and support marine infrastructure. Recent solicitations show state and local buyers treating seawalls as critical coastal resilience assets paired with broader waterfront projects—dock reconstruction, floating platforms, and shoreline stabilization—rather than standalone structures. The City of Long Beach Department of Public Works solicited tieback installation and pile-cap repair for the Naples Vista del Golfo seawall under RFB R-7278 (bids due September 16, 2026), while Monroe County, Florida requested canal stabilization and erosion control adjacent to an existing seawall at the Old Marathon Tax Collector Building (quotes due July 15, 2026). Work under this code spans concrete cap repair, high-strength steel anchor tieback fabrication and installation, riprap revetment construction, lightweight cellular concrete placement, marine pile wrapping and jacket installation, and environmental compliance tied to coastal zone management and endangered-species protection. Issuing bodies include coastal cities (Long Beach, St. Pete Beach, Sarasota, Cocoa), county governments (Monroe County, Broward County), and special-purpose districts (Chatham Area Transit Authority for a ferry dock and shelter with integrated dock work, Brazos River Authority for marina loading and fishing docks). Work surfaces across Florida, California, Texas, Georgia, and South Carolina, concentrated heavily in Florida's Gulf Coast and Atlantic jurisdictions where hurricane resilience and intracoastal protection drive procurement.

Recent seawall and waterfront structure opportunities emphasize compliance with prevailing-wage requirements, environmental permitting (U.S. Army Corps of Engineers, state water management districts, coastal commissions), and marine-specialized insurance (Protection & Indemnity coverage, marine pollution liability). The City of Long Beach R-7278 bid scope required 71 tieback anchors at 29-kip design load, 55 linear feet of pile-cap crack repair, and 231 square feet of spall repair under California's 2022 Building Code and Greenbook standards, with a California Class A license and ten years of prior tieback-barge experience mandatory—a restrictive gate reflecting technical specialization in the market. Monroe County's Old Marathon Tax Collector project combined riprap placement, grout stabilization, and silt fence installation under Davis-Bacon prevailing wage (federally funded Hurricane Irma mitigation). Performance and payment bonds at 100 percent of contract value are standard; bid security ranges from 5 to 10 percent. Contract terms typically run 90 to 180 days for substantial completion, with liquidated damages of $250–$2,712 per day for delays. A subset of recent seawall work has incorporated marine construction broader than seawall-specific scope—Chatham Area Transit Authority's ferry dock award included integrated piling, concrete platforms, and shelter construction alongside dock work, signaling that UNSPSC 95121621 frequently appears in mixed-scope waterfront bids. Buyers name addenda and clarifications addressing technical requirements, pile design, stone gradation, and environmental compliance—indicating active pre-bid engagement and design-phase risk management. The code shows sustained mid-range activity across state and local jurisdictions with coastal exposure, with no standout repeat buyer but consistent demand from Florida's coastal counties and Texas waterfront authorities pursuing resilience and public-access upgrades.
