U.S. awards dam safety monitoring upgrade contract for Dworshak dam and hydro project in Idaho

The U.S. Army Corps of Engineers awarded Oregon-based Jensen Drilling Company a $1.94 million contract to upgrade the dam safety monitoring system at the 402-MW Dworshak dam and hydroelectric project in Idaho.

The three-unit Dworshak hydro project began generating electricity in 1973 on the Clearwater River.

The Corps’ Walla Walla District seeks an upgrade including replacement of vibrating wire sensors inside the dam, installation of new sensors and communication cabling and related hardware, upgrade or replacement of the automated data acquisition system, supply and commissioning of network-based data handling and presentation software and minor civil works.

In other news, the Corps awarded Alstom Power Inc. a $2.18 million contract to rewind main generator Unit 3 at the 810-MW Lower Granite hydroelectric project on the Snake River in Washington.
