Heavy-Lift Barge Transportation and Delivery

The contract calls for the marine transportation of two massive 425-ton gate leaves from an offsite fabrication yard to McNary Dam, requiring specialized heavy-lift barge operations and comprehensive marine logistics planning. Detailed stability analysis must be conducted to ensure safe transit under varying water conditions, and coordination with port authorities is essential to manage scheduling, loading, and unloading operations within strict operational constraints. The work is scoped to include all vessel preparation, securing and bracing of the gate leaves, route planning, and compliance with federal navigation and safety regulations. The contract is classified as a subcontract under NAICS code 483110, reflecting its focus on water transportation of cargo. It is administered by the U.S. Army Engineer District Walla Walla under the Department of Defense, with performance tied to the dam’s location at ZIP code 97882. The solicitation was posted on May 1, 2026, and responses must be submitted by 10:00 PM on May 12, 2026. While there is no set-aside designation, the project demands a contractor with proven expertise in heavy-lift marine transport, complex port coordination, and the ability to deliver mission-critical infrastructure components without disruption to dam operations or environmental compliance standards.
