This document is a set of supplemental drawings for the Ice Harbor Lock and Dam Temporary Modular Powerhouse (TMP) project issued by the U.S. Army Corps of Engineers. The drawing index lists 11 supplemental drawings to the project specifications, including structural plans at various elevations (EL. 368.5, 349.5, and 286.00), transverse sections, erection bay stair details, and component details for draft tube liners and mandoors.

The supplemental drawings provide detailed construction documentation for the Ice Harbor Lock and Dam powerhouse facility. The drawings include comprehensive plans and cross-sections showing the layout of the powerhouse structure, generator bays, pipe gallery plans, and associated mechanical components. Key drawings depict the draft tube liner assembly with dimensional specifications and field weld joint details (Drawing 5846-MV-1 and 5846-ABT-1), as well as a 24"x36" mandoor frame assembly and mandoor components (Drawings 1310-FB-1, 1310-QR-1, and 1310-00-1). The technical drawings incorporate elevation markers, structural details, section views, notes regarding grinding and welding requirements, and material specifications necessary for fabrication and installation of the powerhouse equipment and structural elements. These supplemental drawings serve as reference documents supporting the main project specifications for construction and fabrication activities.
