U.S. Extends Bidding for Fish Passage
The U.S. Army Corps of Engineers has extended the deadline for bids to perform major construction to upgrade the juvenile fish passage facility at 810-MW Lower Granite Dam on the Snake River in Washington. Bids now are due Aug. 19.
The Corps' Walla Walla District previously called for bids by Aug. 1. It requested information last year on firms able to perform the work. The Corps issued a $2.7 million contract in July to Engineered Heavy Services LLC to modify a juvenile fish collection channel at the project. Other recent actions involving fish passage include a call for a lamprey migration and passage study at Lower Granite and three other projects.
The Walla Walla District now seeks bids for the Lower Granite Juvenile Fish Facility Phase 1a. The work is to construct an upgraded fish passage system to provide additional water through enlarged 14-inch orifices. To accommodate the added flow, the Corps said concrete mining is required to enlarge the existing collection channel and the existing transportation channel.
A new section of transportation channel is to be mined through the dam to exit the downstream face of the dam. Additionally, a new transportation channel and associated systems are to be installed from the dam to the juvenile fish facility.
The work is expected to cost $25 million to $100 million.
