Att. B - Dworshak Photos - Existing site & historical construction.pdf

This is an attachment file containing photographs of the existing Dworshak Dam site and historical construction documentation. The file serves as a visual reference document for the Dworshak Unit 4 expansion project, providing imagery of the current powerhouse facility, site conditions, and construction history relevant to the planned installation of a fourth generating unit and associated powerhouse structure extension at Dworshak Dam located on the Clearwater River near Ahsahka, Idaho.

The photographs document the existing site infrastructure and historical construction context that prospective contractors should review in preparation for the industry one-on-one sessions scheduled for May 4-5, 2026, with overflow sessions on May 11, 2026. This visual documentation is intended to support industry understanding of the project scope and site conditions as the U.S. Army Corps of Engineers Walla Walla District develops multiple acquisition packages for the powerhouse expansion work.
