DRAFT Contract Drawings.pdf

This document is a request for information from the U.S. Army Corps of Engineers regarding a turbine rehabilitation and generator rewind project at the Norfork Powerhouse. The Corps seeks industry feedback on draft specifications, drawings, and evaluation criteria by July 16, 2021 for a future construction contract solicitation. An in-person pre-solicitation site visit will be held on June 30, 2021. The project involves designing and installing new Francis turbines, improving dissolved oxygen levels, rewinding existing generators, and refurbishing associated equipment at the Norfork Powerhouse located near Salesville, Arkansas. The turbines were manufactured by S. Morgan Smith Company in 1944 and have exceeded their design life. The latest design and aerating technologies should be applied to develop aerating capability for the replacement turbines.
