DWA Unit 4 Project Overview - Concept Sketch.pdf

This document is a project overview for a federal infrastructure expansion initiative managed by the U.S. Army Corps of Engineers. The project scope involves expanding the generation capability of the Dworshak Dam Powerhouse by installing a fourth generating unit, designated as Main Unit 4, along with an associated powerhouse structure extension.

The document includes a photograph of the existing powerhouse facility and a conceptual schematic depicting the proposed expansion. The new concept sketch illustrates the addition of Bay 4 to the assembly bay area, with designated zones for open skeleton bays, three-phase transformer equipment (XFMR), fill and paving, and penstocks numbered 5 and 6. The visual representations demonstrate the spatial relationship between the existing powerhouse infrastructure and the planned structural modifications required to accommodate the fourth generating unit. No specific timeline, budget allocation, response deadlines, or contracting vehicle information is provided in this overview document.
