UNSPSC 22110111: Dolphin structure

A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Dolphins as the name implies are used for mooring only and for securing the vessels by using ropes. They are also commonly used near pier structures to control the transverse movement of berthing vessels.

UNSPSC 22110111 Dolphin structure is a Commodity code under which state and local governments procure marine infrastructure components, specifically structural dolphins and related mooring systems used in waterfront and maritime facilities. Based on recent solicitations, the work encompasses replacement and installation of steel pipe piles, timber support structures, and associated pier infrastructure at state parks and recreational facilities. State Parks and Recreation Commissions represent the primary issuing bodies for this code, supported by broader cooperative purchasing vehicles such as Sourcewell that aggregate law enforcement equipment and related marine or structural procurement across multiple jurisdictions, counties, and special-purpose districts.

The Washington State Parks and Recreation Commission posted a representative opportunity in March 2026 (Reid Harbor Moorage Improvements at Stuart Island State Park, IFB NWC3914R, due April 21, 2026) for the replacement of timber support dolphins with steel pipe piles as part of a broader moorage modernization project. The bid range was $2,462,796.00 to $3,010,084.00, with mandatory prevailing wage compliance and apprentice labor participation requirements under Washington state law. The in-water work window runs September 1, 2026 through February 5, 2027, and contractors must demonstrate marine construction, structural steel fabrication, and pile-driving expertise, along with environmental compliance and marine mammal monitoring capabilities. Sourcewell's cooperative RFP #061626 (posted May 12, 2026, due June 16, 2026) references law enforcement equipment but does not reflect primary activity under this Commodity code; the Stuart Island project represents the concrete procurement signal for dolphin structure work in the recent state and local market.
