UNSPSC 81101503: Harbor or water ports engineering

UNSPSC 81101503 Harbor or water ports engineering, a Commodity code, encompasses professional consulting and engineering services for water resource planning, coastal protection, marine infrastructure design, permitting, and construction management that state and local governments procure to develop, maintain, and improve harbors, ports, marinas, waterway systems, and waterfront assets. Recent solicitations show state and local buyers contracting for water resources master plan updates, on-call coastal engineering support, marina operations and redevelopment, marine asset inspection and design, jetty and pier feasibility studies, and boat ramp improvements—work that spans design, environmental review, regulatory coordination, construction oversight, and asset management across interior waterways and ocean-adjacent shorelines.

Issuing bodies under this code include city water resources departments, county boards of commissioners, state departments of transportation, municipal utilities departments, county parks and recreation services, and water resource districts. Recent activity concentrates in the Southeast and Southwest, with recent solicitations from Beaufort County South Carolina, the City of Scottsdale Arizona, the City of Sebastian Florida, Orange County Florida, Jackson County Missouri, and the State of Utah. Representative opportunities include Beaufort County's RFQ for on-call marine and coastal engineering services (due April 7, 2026) selecting up to three qualified firms at up to $750,000 annually per consultant for marine inspections, bridge evaluation, design of docks and seawalls, dredging, hydrographic surveys, permitting coordination, and resilience planning; the City of Scottsdale's SOQ for update of its Integrated Water Resources Master Plan (due August 7, 2026); and the City of Detroit's RFP for marina operations and development at Riverside and Erma Henderson marinas (due June 15, 2026) requiring bidders to demonstrate five years of marina ownership or commercial maritime development experience and submit a twenty-year capital investment plan.
