About this file
These engineering design drawings are for an Upstream Tainter Gate Supply for the Navigation Lock at Ice Harbor Lock and Dam, located on the Snake River across Oregon, Washington, and Idaho. The documents specify detailed technical requirements for fabricating a large hydraulic gate structure, with a focus on trunnion hub assembly details, structural steel specifications, and precise manufacturing tolerances. Key technical specifications include using ASTM A709 F-2 Grade 50 structural steel, ASTM A668 Class D trunnion hubs, and adhering to AWS D1.5 welding standards. The fabricator must be certified under the American Institute of Steel Construction (AISC) Quality Certification Program with specific fracture control endorsements. The design drawings provide comprehensive manufacturing details, including dimensional tolerances, welding requirements, and assembly instructions for the gate's complex structural components.
The drawings are part of a U.S. Army Corps of Engineers project in the Walla Walla District, with a solicitation number W912EF26BA001 and a project date of November 2025. The technical specifications are extremely precise, with control dimensions requiring tolerances as tight as ±0.002" for certain measurements. Design codes referenced include EM 1110-2-2107 for hydraulic steel structures, AISC Steel Design Manual, and ASCE 7-22 load criteria. The documents include detailed notes on welding techniques, painting specifications (vinyl system 5-E-Z), post-weld thermal stress relief requirements, and strict guidelines for fabrication and material preparation.
