About this file

Written by GovTribe AI · Dec 5, 2025

These engineering design drawings detail the specifications for an Upstream Tainter Gate Supply for the Navigation Lock at the Ice Harbor Lock and Dam, located on the Snake River across Oregon, Washington, and Idaho. The project is being managed by the U.S. Army Corps of Engineers Walla Walla District, with a contract/solicitation number W912EF26BA001 issued in November 2025. The technical drawings (sheets S-301, S-502, S-506, and S-507) provide comprehensive engineering details for gate sections, gate ribs, seal installations, and mounting components, including precise measurements, material specifications, welding requirements, and structural configurations for the tainter gate's various components such as vertical ribs, girder plates, trunnion arms, seals, and mounting brackets.

The drawings specify technical requirements for gate construction, including detailed specifications for plate thicknesses, welding types (such as Complete Joint Penetration welds), material grades, and mounting hardware. Specific design elements include upper and lower vertical ribs, intermediate ribs, holding anchor brackets, side and bottom seals, and intricate mounting configurations. The designs incorporate precise dimensional tolerances, radius measurements, and specialized mounting techniques, with notes indicating that certain components like seals and hardware are "Not in Contract" (N.I.C.), suggesting these may be procured separately. The technical drawings are signed by Julio Morelos, P.E., and dated December 4, 2025, with multiple review and revision notations.
